    The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child. The child presented with an acute onset of significant visual impairment and headache. His vision gradually improved after trans-nasal sphenoidotomy and drainage of the sinus content with return of complete normal baseline vision after 2 months. (orig.)

    Full Text Available Introduction: The sphenoid adenoid cystic carcinoma is a rare malign neoplasm, in the head and neck and when located in the paranasal sinuses, it is formed in the minor salivary glands. It grows slowly and is characterized by a large invasion of the adjacent tissues, and also has a large capacity of metastasis. The surgery associated with post-operative radiotherapy is used as treatment. Objective: To describe a case of sphenoid sinus adenoid cystic carcinoma in a male, black, 62 year patient. Case Report: N.L.B., 62 years of age, male, had bloody rhinorrhea for 6 months associated with bilateral nasal obstruction. The nasofibroscopy showed lesion of polypoid aspect in the left nasal cavity. He was submitted to biopsy and the anatomopathological exam showed adenoid cystic carcinoma and the patient was forwarded to oncology. Conclusions: The importance of conducting the differential diagnosis between chronic nasosinusal infection and nasosinusal tumors.

    Invasive fungal sinusitis is a rare condition that usually occurs in immunocompromised patients and often presents as an orbital apex syndrome. It is frequently misdiagnosed on presentation and is almost always lethal without early treatment. Retrospective case series of 14 consecutive patients with biopsy-proven invasive fungal sinusitis from four tertiary hospitals. Fourteen patients (10 men and 4 women; age range 46-82 years). Retrospective chart review of all patients presenting with invasive fungal sinusitis between 1994 and 2010 at each hospital, with a close analysis of the tempo of the disease to identify any potential window of opportunity for treatment. Demographic data, background medical history (including predisposing factors), symptoms, signs, radiological findings, histopathological findings, treatment approach and subsequent clinical course were recorded and analysed. Only one patient was correctly diagnosed at presentation. Only two patients were not diabetic or immunocompromised. The tempo was acute in two patients, subacute in nine patients and chronic in three patients. In the subacute and chronic cases, there was about 1 week of opportunity for treatment, from the time there was a complete orbital apex syndrome, and still a chance for saving the patient, to the time there was central nervous system invasion, which was invariably fatal. Only two patients survived - both had orbital exenteration, as well as antifungal drug treatment. Invasive fungal sinusitis can, rarely, occur in healthy individuals and should be suspected as a possible cause of a progressive orbital apex syndrome. © 2012 The Authors.

    Full Text Available Introduction: The sphenoid sinus is often neglected because of its difficult access. The deep position of the sphenoid sinus hinders early diagnosis of pathologies in that location. Delayed diagnosis can cause serious complications due to proximity to many important structures. Objectives: The aim of this study is to demonstrate different pathologies which can affect the sphenoid sinus and elucidate the findings. Methods: Cases of isolated sphenoid sinus lesions encountered in the neurosurgical setting which had rare pathologies are discussed. Pathologies such as Langerhans cell histiocytosis, solitary plasmacytoma, chordoma, pituitary adenoma, leiomyosarcoma, fungal infection, and mucocele which appeared primarily in sphenoid sinus are discussed along with their imaging features and pathological findings. Conclusion: Multitude of different pathologies can occur in sphenoid sinus. Detailed preoperative imaging is very helpful, but transnasal biopsy and histological study are required often for definitive diagnosis. The possible advantages of early diagnosis before spread of pathology for prognosis cannot be overemphasized.

    This review summarizes the most relevant articles from the field of neuro-ophthalmology published in the Journal of Neurology from January 2012 to July 2013. With the advent of video-oculography, several articles describe new applications for eye movement recordings as a diagnostic tool for a wide range of disorders. In myasthenia gravis, anti-Kv1.4 and anti-Lrp4 have been characterized as promising novel autoantibodies for the diagnosis of hitherto 'seronegative' myasthenia gravis. Several articles address new diagnostic and therapeutic approaches to neuromyelitis optica, which further sharpen its profile as a distinct entity. Additionally, 4-aminopyridine has become a standard therapeutic for patients with cerebellar downbeat nystagmus. Finally, revised diagnostic criteria have been proposed for chronic relapsing inflammatory optic neuropathy based on a careful literature review over the last decade.

    The sphenoidal sinus lesions, which were documented by sinus CT, were found in 32 sides of sphenoidal sinus of 19 patients seen in 14 months from January 1984 to February 1986. Sphenoiditis was frequently seen as in 17 % in the all poly-sinusitis, and sphenoidals cysts were seen in 4 side in 3 patients. The indications of the sphenoiditis by CT were thickening of the mucosa and opacificasion with soft tissue density. By sphenoid cysts, no contrast enhancement was seen and margins of the cyst wall were smooth and regular with bone erosion. Since erosion of the bone is also seen in Wegener's granulomatosis and carcinoma, the CT image of the bone erosion is not specific to either of them and does not contribute to the definitive diagnosis of malignancy.

    The neuro-ophthalmological examination constitutes one of the most refined and exact components of the clinical examination, often allowing precise diagnosis and formulation of a treatment plan even within the compass of the first visit. This chapter briefly highlights important features in the neuro-ophthalmological history and then presents detailed information on the important components of a comprehensive neuro-ophthalmological examination. Covered examination topics include visual acuity, visual field testing, color vision, external eye exam, pupils, ophthalmoscopy, and eye movements. The final section discusses ancillary tests that supplement the bedside neuro-ophthalmological examination, including formal visual field analysis, electroretinography, fluorescein angiography, ocular coherence tomography, visual-evoked potentials, neuroimaging, and quantitative eye movement recordings.

  13. Three cases of ectopic sphenoid sinus pituitary adenoma

    Directory of Open Access Journals (Sweden)

    Ernest Jan Bobeff

    2017-03-01

    Full Text Available Introduction : Ectopic sphenoid sinus pituitary adenoma is a rare tumour originating from embryologic remnants of Rathke’s pouch. Although it is considered a clinically benign neoplasm, necrosis is encountered in 25% of cases and it can invade adjacent bone structures. Aims : To establish clinical, radiological and histopathological features of ectopic sphenoid sinus pituitary adenoma. Material and methods: Analysis of three cases: two females and one man, aged 61-70. Results : One patient presented with a unilateral hearing loss, the other two with headache and vertigo. They all suffered from type 2 diabetes mellitus. Neurological examination revealed no abnormality. Radiological imaging showed a sphenoid sinus space-occupying soft-tissue lesion with bone erosion in 2 cases and empty sella in 2 patients whereas one had a normal pituitary gland. All were operated on via the transnasal approach. Total resection was achieved in one patient and subtotal in two; in two cases we observed intact sellar dura and in one intact sellar floor. Histopathology showed immunoreactivity for synaptophysin in all cases and cytokeratin in two. The Ki-67 index was less than 2%. Immunohistochemical staining demonstrated growth hormone cells in all cases whereas prolactin and adrenocorticotropin in two. The patients were discharged home in good condition with no neurological deficits. Conclusions : Ectopic sphenoid sinus pituitary adenoma should always be considered in differential diagnosis of sphenoid sinus lesion in the elderly, especially in coexistence with empty sella or type 2 diabetes mellitus. Since ectopic sphenoid sinus pituitary adenoma is a benign lesion, surgical removal is an effective treatment.

    Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78- year-old male patient who presented with right hemifacial pain, headache and toothache. CT revealed the presence of an expansile cystic mass lesion in the sphenoid sinus that showed a high signal intensity on both the T1 and T2 weighted images. This mass was later determined to be CG. The suspected etiologic mechanisms of both CG and aspergilloma of the paranasal sinuses are similar, and impaired drainage and obstruction of the ventilation of the paranasal sinuses are considered to be the causative mechanism of both diseases. Overall, the results of this study indicate that the use of MRI findings could be helpful for differentiating CG from other paranasal sinus mass lesions

    Background/aim: Isolated sphenoid sinus-derived lesions are rare and generally present with unclear symptoms. We are sharing our experience to be mindful of such lesions in differential diagnosis and to help accomplish successful treatment while avoiding revisions and complications.Materials and methods: Data from patients who underwent isolated sphenoid sinus surgeries (ISSs) were retrospectively extracted from the period of January 2005 to August 2015. Demographic data, chief complaints and presenting symptoms, imaging findings, surgical management, and results were evaluated. Results: There were 40 patients who underwent ISS. These patients had different pathologies. The chief complaint was nonspecific headache, except for cerebrospinal fluid leak patients who presented with serous rhinorrhea. Conclusion: It is critical to investigate suspicious symptoms with clinical findings and imaging techniques to avoid late diagnoses of isolated sphenoid pathologies. The transnasal approach is more minimally invasive and tissue-sparing. In our experience, we have noted that excising the inferior one-third of the superior turbinate decreases revisions. On the other hand, results show that the presence of concomitant pathology and invasive fungal disease increases the risk of revision surgery and complications.

    Neuro-ophthalmology is a medical subspecialty concerned on the nervous system diseases with ocular manifestations, this could be both sensory and motor, including ocular movements, papillary responses, and the structure changes of the brain and nervous system with ocular manifestations. Although neuro-ophthalmology in China has achieved some progress, certain problems still exist, such as the professional neuro-ophthalmology team and related academic organization are still absent in China; neuro-ophthalmology knowledge has not been popularized; the new technologies for diagnosis and treatment in neuro-ophthalmology have not been absorbed and applied; the coordination and cooperation with other related disciplines are not enough. We should actively promote the development of neuro-ophthalmology in China, including organization of a professional team of neuro-ophthalmology, popularization of neuro-ophthalmology knowledge to the ophthalmologists, development of research work in neuro-ophthalmology and the collaboration with international neuro-ophthalmologists.

    About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. The sphenoid sinuses are rarely involved. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. Thus, barotrauma could lead to serious neurologic disorders, including blindness. After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge. Therefore, information is provided, e.g. on anatomical and pathophysiological features. Divers and physicians should have in mind that occasional headache during or after diving sometimes signals serious neurological disorders like vision loss. We show that injuries can develop from both negative and positive pressures in the sinuses. Because visual recovery depends on prompt diagnosis and proper therapy, physicians like otolaryngologists, ophthalmologists and neurologists need to closely collaborate.

    Purpose : Primary sphenoid carcinoma is rare. It accounts for 0.3% of all primary paranasal sinus malignancies. Because of the rarity of sphenoid carcinoma, large series of patients with outcome and survival statistics are currently unavailable. So we followed up the 1 case of sphenoid sinus carcinoma treated in our hospital and reported the course of the disease. In a review of case reports and small series of patients, 2-year survival was 7%. Our case is alive at 29 months after diagnosis of sphenoid sinus carcinoma. Intramedullary spinal cord metastasis (ISCM) is an unusual complication of cancer. In our case rapidly progressive paraparesis and urinary retention developed at 25 months after diagnosis of sphenoid sinus carcinoma. MRI of the thoracic spines showed the intramedullary spinal cord tumor mass at T3 and T4 level with accompanying syringomyelia. Here we report a case of ISCM associated with syringomyelia which has developed after primary sphenoid sinus carcinoma with a review of literature about the clinical behavior and treatment of this lesion.

    We describe a rare case of a sphenoid sinus myxoma that was resected via an endoscopic endonasal skull base approach. We review the literature regarding these rare tumors of the paranasal sinuses. A 72-year-old woman was diagnosed with an incidental sphenoid sinus tumor and left sphenoid wing meningioma during a workup for left-sided proptosis and diplopia. Biopsies of the sphenoid wing and sphenoid sinus tumors were obtained. After undergoing surgical resection of the meningioma, the patient then underwent definitive resection of the sphenoid sinus myxoma via endoscopic endonasal skull base approach. Postoperative imaging demonstrated a gross total resection. The patient suffered postoperative thromboembolic complications due to underlying hypercoagulable state but made a complete recovery and returned to her neurologic baseline. There has been no evidence of recurrent myxoma in the sphenoid sinus 24 months after surgery. Myxomas are benign tumors derived from primitive mesenchyme. Myxomas very rarely present in the paranasal or skull base location. Complete surgical resection is the primary treatment for these tumors. The endoscopic endonasal approach is an effective technique for resecting various benign and more aggressive extradural skull base tumors. Myxomas of the sphenoid sinus are rare. The endoscopic endonasal skull base approach is an effective and minimal access technique for resection of this rare tumor of the sphenoid sinus. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Spontaneous sphenoid sinus lateral wall meningoceles are rare lesions with an unknown etiology. Endoscopic endonasal technique is a considerable route in the treatment of this condition. The aim of this paper is to report the etiology, surgical technique, and outcome in a patient repaired via endoscopic endonasal approach. A 51-year-old male patient applied with rhinorrhea started three months ago after an upper respiratory infection. There were no history of trauma or sinus operation. Biochemical analysis of the fluid was positive for beta-2-transferrin. This asypthomatic patient had undergone for repairment of lateral sphenoid sinus meningocele with endoscopic endonasal transsphenoidal approach. After endoscopic endonasal meningocele closure procedure no complications occured and a quick recovery was observed. Endoscopic endonasal approach is an effective and safe treatment modality of spontaneous lateral sphenoid sinus meningoceles and efficient in anterior skull base reconstruction.

    After sinus surgery, patients are commonly instructed to irrigate with saline irrigations with their heads over a sink and noses directed inferiorly (nose-to-floor). Although irrigations can penetrate the sinuses in this head position, no study has assessed whether sphenoid sinus penetration can be improved by irrigating with the nose directed superiorly (nose-to-ceiling). The purpose of this study was to use a validated computational fluid dynamics (CFD) model of sinus irrigations to assess the difference in sphenoid sinus delivery of irrigations after irrigating in a nose-to-floor vs nose-to-ceiling head position. Bilateral maxillary antrostomies, total ethmoidectomies, wide sphenoidotomies, and a Draf III frontal sinusotomy were performed on a single fresh cadaver head. CFD models were created from postoperative computed tomography maxillofacial scans. CFD modeling software was used to simulate a 120-mL irrigation to the left nasal cavity with the following parameters: flow rate 30 mL/second, angle of irrigation 20 degrees to the nasal floor, and either nose-to-floor or nose-to-ceiling head positioning. In the postoperative CFD models, the sphenoid sinuses were completely penetrated by the irrigation while in a nose-to-ceiling head position. However, no sphenoid sinus penetration occurred in the nose-to-floor position. Other sinuses were similarly penetrated in both head positions, although the ipsilateral maxillary sinus was less penetrated in the nose-to-ceiling position. CFD modeling demonstrated that the nose-to-ceiling head position was superior to the nose-to-floor position in delivering a 120-mL irrigation to the sphenoid sinuses. © 2017 ARS-AAOA, LLC.

    Ewing's sarcoma is a high-grade neuroectodermal primary bone tumor. This is the second primary bone tumor in children afterosteosarcoma and represents 4 to10% of cases. It can occur in all skeletal bones. However, the location at the facial bones is uncommon (1to2%) and extremely rare at the sphenoid sinus. We report the clinical results of a rare case of Ewing's sarcoma of the sphenoid with intraorbitaland intracranial extension.

    Sphenoid sinusitis is unusual in children, but when it occurs, it can lead to serious intracranial complications. We show the value of MRI in demonstrating intracranial abnormalities due to sphenoid sinus infection, particularly those involving the internal carotid arteries and cavernous sinuses. We reviewed our imaging experience of sphenoid sinusitis and found four patients with ICA narrowing who had undergone MR evaluation including conventional and diffusion imaging. MR angiography was also performed in three patients to determine the extent of ICA narrowing. Narrowing of ICA was found in the cavernous segment in all patients and in the supraclinoid segment in three. Cerebral infarction was found in two patients. In one patient the cavernous sinus showed hyperintensity on diffusion-weighted images and hypointensity on apparent diffusion coefficient map, suggesting reduced diffusion. Although infrequent in children, sphenoid sinus infection should be considered as a possible cause of intracranial infection, particularly in teenagers. Early recognition of cavernous sinus involvement and ICA narrowing may lead to prompt treatment and hence a more favorable outcome. (orig.)

    Arrested pneumatization of the sphenoid sinus is a developmental variant that is not always well recognized and is often confused with other pathologies associated with the skull base. This report describes the case of a patient referred for cone-beam computed tomography (CBCT) imaging for dental implant therapy. CBCT demonstrated a well-defined incidental lesion in the left sphenoid sinus with soft tissue-like density and sclerotic borders with internal curvilinear opacifications. The differential diagnoses included intraosseous lipoma, arrested pneumatization of the sphenoid sinus, chondrosarcoma, chondroid chordoma, and ossifying fibroma. The radiographic diagnosis of arrested pneumatization was based on the location of the lesion, its well-defined nature, the presence of internal opacifications, and lack of expansion. Gray-scale CBCT imaging of the area demonstrated values similar to fatty tissue. This case highlighted the fact that benign developmental variants associated with the skull base share similar radiographic features with more serious pathological entities.

    Although mucocele is a benign lesion, its unavoidable expansions may result in irreversible damages in adjacent organs. In spheno-ethmoid mucoceles which are extremely rare, this condition may cause more severe problems. Central diabetes insipidus, developed secondary to sphenoid sinus mucocele, was detected in a 54-year-old male patient, who underwent endoscopic sinus surgery 2 times due to nasal polyposis. Endoscopic sphenoid mucocele marsupialization was performed to the patient, but despite partial regression in the 1-year follow up, complete recovery was not observed. Copyright © 2014 Elsevier Inc.

    2015-09-01

    Paraneoplastic syndromes that affect the visual pathways and present with neuro-ophthalmologic signs or symptoms may involve the afferent or efferent systems. Afferent syndromes may involve the optic nerve or retina and, in some cases, these may be associated with systemic neurologic disease. Efferent symptoms typically affect eye movements and may involve the neuromuscular junction or involuntary eye movements. Literature review and personal clinical and research experience. Diagnosis of paraneoplastic syndromes relies on clinical and laboratory evaluations. In the appropriate clinical setting, the presence of specific antibodies may help confirm the diagnosis. In some cases, the visual pathway disturbance precedes a diagnosis of malignancy. Astute observation and selective evaluation and management are critical to establish the correct diagnosis and institute therapeutic approaches that can be sight or life saving.

    Neuro-ophthalmology is a field combining neurology and ophthalmology that studies diseases that affect the visual system and the mechanisms that control eye movement and pupil function. Imaging tests make it possible to thoroughly assess the relevant anatomy and disease of the structures that make up the visual pathway, the nerves that control eye and pupil movement, and the orbital structures themselves. This article is divided into three sections (review of the anatomy, appropriate imaging techniques, and evaluation of disease according to clinical symptoms), with the aim of providing useful tools that will enable radiologists to choose the best imaging technique for the differential diagnosis of patients' problems to reach the correct diagnosis of their disease.

    Body identification is the cornerstone of forensic investigation. It can be performed using radiographic techniques, if antemortem images are available. This study was designed to assess the value of visual comparison of the computed tomography (CT) anatomical aspects of the sphenoid sinuses, in forensic individual identification, especially if antemortem dental records, fingerprints or DNA samples are not available. This retrospective work took place in a French university hospital. The supervisor of this study randomly selected from the picture archiving and communication system (PACS), 58 patients who underwent one (16 patients) or two (42 patients) head CT in various neurological contexts. To avoid bias, those studies were prepared (anonymized, and all the head structures but the sphenoid sinuses were excluded), and used to constitute two working lists of 50 (42+8) CT studies of the sphenoid sinuses. An anatomical classification system of the sphenoid sinuses anatomical variations was created based on the anatomical and surgical literature. In these two working lists, three blinded readers had to identify, using the anatomical system and subjective visual comparison, 42 pairs of matched studies, and 16 unmatched studies. Readers were blinded from the exact numbers of matching studies. Each reader correctly identified the 42 pairs of CT with a concordance of 100% [97.5% confidence interval: 91-100%], and the 16 unmatched CT with a concordance of 100% [97.5% confidence interval: 79-100%]. Overall accuracy was 100%. Our study shows that establishing the anatomical concordance of the sphenoid sinuses by visual comparison could be used in personal identification. This easy method, based on a frequently and increasingly prescribed exam, still needs to be assessed on a postmortem cohort. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Extramedullary plasmacytomas are localized tumours formed of monoclonal plasma cells in an extra-skeletal area. They constitute approximately 3% of all neoplasms originating from plasma cells. They generally display a destructive course. When the literature in English was reviewed, only 19 cases with the primary disease localized in the sphenoid sinus were found. We present the case of a 50-year-old male patient who presented with gradually increasing visual loss over 6 weeks, whose radiological tests revealed a formation of mass in the sphenoid sinus pressing against the optic nerve and internal carotid artery. A biopsy obtained by endoscopic sinus surgery was reported to be a plasmacytoma. A diagnosis of extramedullary plasmacytoma was made after investigations for other neoplastic plasma cell conditions proved negative. Extramedullary plasmacytomas were assessed by reviewing the literature. Copyright © 2012 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

  19. The Neuro-Ophthalmology of Mitochondrial Disease

    Fraser, J. Alexander; Biousse, Valérie; Newman, Nancy J.

    2010-01-01

    Mitochondrial diseases frequently manifest neuro-ophthalmologic symptoms and signs. Because of the predilection of mitochondrial disorders to involve the optic nerves, extraocular muscles, retina, and even the retrochiasmal visual pathways, the ophthalmologist is often the first physician to be consulted. Disorders caused by mitochondrial dysfunction can result from abnormalities in either the mitochondrial DNA or in nuclear genes which encode mitochondrial proteins. Inheritance of these mutations will follow patterns specific to their somatic or mitochondrial genetics. Genotype-phenotype correlations are inconstant, and considerable overlap may occur among these syndromes. The diagnostic approach to the patient with suspected mitochondrial disease entails a detailed personal and family history, careful ophthalmic, neurologic, and systemic examination, directed investigations, and attention to potentially life-threatening sequelae. Although curative treatments for mitochondrial disorders are currently lacking, exciting research advances are being made, particularly in the area of gene therapy. Leber hereditary optic neuropathy, with its window of opportunity for timely intervention and its accessibility to directed therapy, offers a unique model to study future therapeutic interventions. Most patients and their relatives benefit from informed genetic counseling. PMID:20471050

    Visual disturbances associated with isolated sphenoid sinus inflammatory diseases (ISSIDs) are easily misdiagnosed due to the nonspecific symptoms and undetectable anatomical location. The main objective of this retrospective case series is to investigate the clinical features of visual disturbances secondary to ISSIDs. Clinical data of 23 patients with unilateral or bilateral visual disturbances secondary to ISSIDs from 2004 to 2014 with new symptoms were collected. Collected data including symptoms, signs, neuroimaging and pathologic diagnosis were analyzed. There were 14 males and 9 females, and their ages ranged from 31 to 83 years. Fifteen patients suffered blurred vision and 11 patients suffered binocular double vision, including 3 patients who had unilateral visual changes and diplopia simultaneously. Headache was observed in 18 patients, and orbit pain/ocular pain in 8 patients. Other presenting symptoms included ptosis (4 patients) and proptosis (1 patient). Only 5 patients had nasal complaints. The corrected visual acuities were between NLP to 20/20. Patients with diplopia included 5 with unilateral oculomotor nerve palsy and 6 with unilateral abducens nerve palsy. All patients performed orbital/sinus/brain radiologic examination and found responsible lesions in sphenoid sinus. All patients underwent endoscopic sinus surgery, and 9 patients were found to suffer sphenoid mucocele, 9 with fungal sinusitis, and 5 with sphenoid sinusitis. Visual disturbances improved in 6 patients, and all the patients with diplopia had a postoperative recovery. Visual disturbances resulting from ISSIDs are relatively uncommon, but it is crucial that the patient with new vision loss or diplopia and persistent headache or orbit pain be evaluated for the possibility of ISSIDs especially before corticosteroid administration.

    Ectopic acromegaly is a very rare clinical entity occurring in less than 1% of acromegalic patients. In most cases it is caused by GHRH or rarely GH-secreting neoplasms. Even rarer are ectopic pituitary adenomas located in the sphenoid sinus or nasopharynx that originate from pituitary remnants in the craniopharyngeal duct. This dissertation presents the difficulties in visualizing GH-secreting adenoma located in the sphenoid sinus. A 55-year-old man had somatic features of acromegaly for several years. MRI imaging revealed a slightly asymmetric pituitary gland (14 yen 4 mm) without focal lesions. Simultaneously, a spherical mass, 10 mm in diameter, corresponding with ectopic microadenoma was demonstrated on the upper wall of the sphenoid sinus. The serum GH level was 4.3 mg/l, IGF-1 = 615 mg/l, and a lack of GH suppression with oral glucose was proven. After preliminary treatment with a long-acting somatostatin analogue, transsphenoidal pituitary tumour removal was performed. Histopathological, electron microscopical and immunohistochemical analysis revealed densely granulated somatotropic pituitary adenoma: GH(+), PRL(-), ACTH(-), TSH(-), FSH(-), LH(-), MIB1 pituitary MRI scans, GH and IGF-1 levels 0.18 mug/l and 140 mg/l, respectively, as well as normal GH suppression with oral glucose. The careful analysis of possible pituitary embryonic malformations points out their significance for proper localization of extrapituitary adenomas.

    Headache is an extraordinarily common complaint presenting to medical practitioners in all arenas and specialties, particularly primary care physicians, neurologists, and ophthalmologists. A wide variety of headache disorders may manifest with a myriad of neuro-ophthalmologic symptoms, including orbital pain, disturbances of vision, aura, photophobia, lacrimation, conjunctival injection, ptosis, and other manifestations. The differential diagnosis in these patients is broad and includes both secondary, or symptomatic, and primary headache disorders. Awareness of the headache patterns and associated symptoms of these various disorders is essential to achieve the correct diagnosis. This paper reviews the primary headache disorders that prominently feature neuro-ophthalmologic manifestations, including migraine, the trigeminal autonomic cephalalgias, and hemicrania continua. Migraine variants with prominent neuro-ophthalmologic symptoms including aura without headache, basilar-type migraine, retinal migraine, and ophthalmoplegic migraine are also reviewed. This paper focuses particularly on the symptomatology of these primary headache disorders, but also discusses their epidemiology, clinical features, and treatment. PMID:28539781

    Lesions limited to the sphenoid sinus are relatively rare, and are obscure with respect to symptoms and physical findings. The differential diagnosis of isolated sphenoid sinus disease includes bacterial sinusitis, fungal infection, granulomatous inflammation, mucocele, and tumors. Magnetic resonance imaging (MRI) can provide information that closely reflects the composition of the tissues, sometimes permitting differentiation between pathologically distinct lesions showing similar density by computed tomography. We describe two cases involving mucocele-like lesions of the sphenoid sinus where preoperative MRI revealed a focus of hypointensity within the lesions. In both patients the sphenoid sinus was opened by a transnasal endoscopic approach, and diseased tissue corresponding to the hypointense area was removed under direct endoscopic vision. Histopathological diagnosis revealed colonies of Aspergillus in one case and necrotic granulation tissue without fungus in the other. We concluded that MRI is a crucial part of preoperative evaluation and that the transnasal endoscopic approach represents a safe and effective method for treating nonmalignant isolated sphenoid sinus disease.

    A case report is presented of a 35-year-old woman who developed a progressive right optic neuropathy while surfacing from a series of four recreational dives on the Great Barrier Reef, Queensland, Australia. The patient reported severe sudden onset blurred vision in the right eye associated with a mild headache and epistaxis on surfacing from diving. The patient had her first medical review the day after returning from her trip. At this time visual acuity in the right eye was 20/80, with left eye 20/20. There was a relative afferent pupillary defect in the right eye. A high-resolution computed tomography scan showed fluid in the right sphenoid sinus. Computed perimetry revealed patchy visual field loss in the right eye. The provisional diagnosis of sphenoidal sinus barotrauma-induced optic neuropathy was made. Over 10 days of observation, the visual acuity returned to 20/20 in the right eye and visual field changes resolved. This case highlights a very unusual cause of visual loss associated with diving.

    Sphenoid wing meningiomas (SWMs) typically are histologically benign, insidious lesions, but the propensity of these tumors for local invasion makes disease control very challenging. In this review, we assess whether the degree of resection and extent of cavernous sinus invasion affects morbidity, mortality, and recurrence in patients with SWM. A comprehensive search of the English-language literature was performed. Patients were stratified according to extent of resection and extent of cavernous sinus invasion, and tumor recurrence rate, morbidity, and mortality were analyzed. A total of 23 studies and 131 patients were included. Overall recurrence and surgical mortality rate were 11% and 2%, respectively (average follow-up = 65 months). Cranial nerve III palsy was significantly associated with incompletely versus completely resected SWMs (7 to 0%) as well as meningiomas with cavernous sinus invasion versus no sinus invasion (14 vs. 0%). No significant difference in tumor recurrence rate was noted between these groups. In conclusion, complete excision of SWMs is always recommended whenever possible, but surgeons should acknowledge that there is nonetheless a chance of recurrence and should weigh this against the risk of causing cranial nerve injuries.

    Neuro-ophthalmology, as an interdisciplinary, covers at least three disciplines- ophthalmology, neurology and neurosurgery. With limited knowledge in each discipline, doctors often make misdiagnoses for neuro-ophthalmology diseases. Therefore, it is imperative to abandon the distinction between disciplines and combine all the knowledge to diagnose and treat patients in patterns of holistic integrated medicine in order to effectively improve the diagnosis and treatment of neuro-ophthalmology.

    Basic knowledge and skills are cornerstone of the diagnosis and treatment of neuro-ophthalmology diseases in ophthalmology practice. Due to the interdisciplinary features of neuro-ophthalmology, neuro-anatomy, neuro-physiology related to eyes, neuro-image and neuro-electrodiagnosis, these should be included in the education for the ophthalmologist. Special attention should be paid to training on capability of logically thinking in neuro-ophthalmology. Multiple ways can be used for the education of ophthalmologists and neurologists for the enhancement of basic knowledge and skills of neuro-ophthalmology in China.

    A case of radionecrosis of sphenoid and temporal bones is reported. The patient received a combination of surgery, radiotherapy, and chemotherapy for his left maxillary sinus carcinoma. After the combined therapy, necrosis accompanying inflammation developed in the maxillary and temporal regions. Excision of the necrotic tissues was done, and the left ascending ramus of the mandible was resected because of persistent tumor mass at the left infratemporal fossa. Although the excision wound of the maxilla healed by epithelialization, an area of nonvital bone remained exposed in the temporal region, where progressive osteonecrosis with infection led to breakdown of the skin. The necrotic bones of the zygomatic arch and the sphenotemporal sutural region became visible through the skin defect, and computerized tomography scan revealed bone necrosis involving the inferolateral area and the base of the skull. Excision of the necrotic bone and reconstruction with sternocleidomastoid myocutaneous flap were performed.

    To show a rare case of Cushing's disease and possible cause of failed transsphenoidal surgery. We report on a 50-year-old woman suffering from ACTH-dependent Cushing's syndrome. Endocrinological work-up including low-dose/high-dose dexamethasone test (Liddle-test) and CRH test were clearly compatible with pituitary origin. Although an MRI showed no pituitary tumor, CRH-stimulated petrosal sinus sampling revealed a significant central-peripheral gradient in ACTH concentrations, rendering Cushing's disease very likely. The patient underwent transsphenoidal surgery with negative exploration of the pituitary gland. After intraoperative re-evaluation of the preoperative MRI, a "polyp" at the bottom of the sphenoid sinus was identified. The intraoperative microscopic aspect as well as instantaneous sections and cytology of a biopsy confirmed an adenoma, which was then removed. Histological analysis demonstrated an ACTH-producing pituitary adenoma adjacent to respiratory mucous membrane consisting of ciliated epithelium with submucous connective tissue. Postoperatively, ACTH concentrations were decreased and intermittent hydrocortisone substitution treatment was initiated. At the 3-month follow up, Cushing's stigmata were found to be alleviated and the hydrocortisone dosage could be reduced. Ectopic pituitary adenoma tissue causing Cushing's disease is extremely rare but a potential cause for surgical failure or re-evaluation.

  12. The human resource crisis in neuro-ophthalmology.

    Frohman, Larry P

    2008-09-01

    Neuro-ophthalmology is facing a serious human resource issue. Few are entering the subspecialty, which is perceived as being poorly compensated compared with other subspecialties of ophthalmology. The low compensation comes from the fact that 1) non-procedural encounters remain undervalued, 2) efforts that benefit other medical specialists are not counted, and 3) the relatively low expenses of neuro-ophthalmologists are not factored into compensation formulas. Mission-based budgeting, which forces academic departments to be financially accountable without the expectation of fiscal relief from medical schools or practice plans, has exacerbated the compensation issue. Solutions must come from within neuro-ophthalmology, academic departments, medical schools, and medical practice plans. They include 1) providing educational resources so that neuro-ophthalmologists need not spend so much time teaching the basics, 2) factoring into compensation the impact of neuro-ophthalmologists in teaching and on revenue generation by procedure-based specialists, 3) improving the efficiency of neuro-ophthalmologists in their consultative practices by providing ample clerical support and other measures, 4) providing contractual salary compensation by departments such as neurosurgery to recognize the contributions made by neuro-ophthalmologists, and 5) reorganizing the academic clinical effort as multidisciplinary rather than departmental.

    Neuro-ophthalmologic conditions require specialized multidisciplinary management, both medical and surgical, for patients affected by visual loss due to nervous system disease. The primary goal of this study is to define the specificity of neuro-ophthalmology within the realm of visual health. The secondary goal is to review clinical care pathways by studying the organization of management, in terms of accessibility to care and personalization of the care pathway. A field study was carried out from February to June 2015, within the ophthalmology service of the Pitié-Salpêtrière University Medical Center in Paris. A 30-minute interview with the patient before or after his or her neuro-ophthalmology consultation was performed, so as to describe the clinical care pathway. The medical records of interviewed patients were also analyzed. Seventeen care pathways (10 women and 7 men) were reviewed. The mean age at appearance of visual involvement was 44.5 years (±8.4 years). If we exclude 3 patients over 66 years and retired, 35.71% were active, 35.71% were disabled, and 28.57% were on sick leave. Ten patients (58.82%) met the criteria for admission to long-term care. The first step had been carried out by local private practitioners. The first physician seen was the general medicine physician (59%), then the private ophthalmologist on an emergency basis (17%). On average, patients went through 8 steps during their care pathway (from 6 to 10 steps) and 14 medical departments were involved. The study showed collaboration with the other services of the University Hospital Department of Vision and Disabilities (notably with the Fondation Rothschild, the Quinze-Vingts National Ophthalmology Hospital and the Fondation Sainte-Marie). In addition to rehabilitation services, health care professionals participating in the outpatient care of the patients included an orthoptist (11.7%), a psychologist (11.7%), and an optician specializing in low vision for visual aids

    Sphenoid sinus mucoceles (SSMs) are rare, benign lesions that can expand, often presenting with ocular symptoms-decreased vision, diplopia, visual field defects, proptosis, and external ophthalmoplegia. Reported cases are few, visual compromise varies, and factors affecting visual prognosis are poorly characterized. We investigate whether prompt surgical intervention (within 2 weeks of visual symptom onset) affects best-corrected visual acuity (BCVA) regained in patients with vision loss secondary to compressive SSM. We present a retrospective review of three cases and published literature to date. Our primary outcome was BCVA regained after surgical intervention; secondary outcomes included change in visual field defect and ophthalmological symptoms other than vision loss. Our three cases of SSM varied in onset, ranging from several hours to several months with patients aged from 13 to 80 years. All patients had severe vision loss to light perception (LP) or worse. Rapid neuro-imaging and urgent surgical intervention improved vision to count fingers at best. Of the two patients who underwent prompt decompression, one improved from no LP to LP and the other did not recover any vision. The patient who had visual loss for 3 months before intervention improved from LP to 20/400. Findings from our literature search, which yielded 12 cases of urgent intervention, supported the variability in visual prognosis despite prompt surgical intervention. SSMs are rare, pathologically benign lesions which can expand to cause ocular involvement. Prompt diagnosis and surgical decompression are recommended, but visual recovery may be limited even with urgent intervention.

    Miller Fisher syndrome (MFS), a variant of Guillain-Barré syndrome, is a rare disorder typically characterized by a triad of ataxia, areflexia, and ophthalmoplegia, which may have a highly variable clinical presentation. We report a case of MFS in a 45-year-old female presenting with sphenoid sinusitis and sixth nerve palsy. She underwent endoscopic sphenoid sinusotomy without improvement, had postoperative deterioration, was diagnosed with MFS, and was treated with intravenous immunoglobulin with complete response. Because of the potential severity of Guillain-Barré syndrome, great vigilance should be taken when examining sixth nerve palsies to prevent misdiagnosis and delay in treatment of the MFS variant of this disease.

    A patient surviving after a metal projectile penetrates the sphenoid sinus is unusual. Removing a foreign object from this region is challenging because of the difficult access and proximity to delicate structures. The use of navigation-guided endoscopy makes the manipulation of the surgical instruments near delicate structures safer, and the procedure is minimally invasive. A computed tomographic scan of brain showed the projectile located at the base of the left sphenoid sinus. To prevent infection and irritation and avoid secondary surgical damage, navigation-guided endoscopy was used to remove the bullet. Using the BRAINLAB navigation system, the movement of the endoscope could be followed on the screen, and the tip could be navigated into close contact with the projectile. The bullet could be located, without being visible through the endoscope, making the incision and removal of the bony wall of the sinus minimal; it was removed without complications. Intraoperative navigation of endoscopes is very useful because it enables the surgeon to correlate the visual information through the endoscope with the localization of the instruments seen on the navigation screen. Patient safety and reinforced self-confidence of surgeons are advantages of this procedure. Reduced operative time may not always occur because of a lack of experience with the navigation system. When there are no vascular or neurologic complications, a minimally invasive treatment using nasal navigation-guided endoscopic removal can limit the potential surgical damage.

    In the last decade, with the advances of optical coherence tomography (OCT) technology, different imaging protocols and analysis algorithms have been introduced to maximize the potential of this diagnostic tool in the evaluation of different eye diseases. This review aims to provide an update on these additional features, with respect to the management of a diverse range of neuro-ophthalmologic conditions. Macular ganglion cell complex (mGCC) analysis has been shown to be superior to peripapillary retinal nerve fiber layer (pRNFL) analysis in certain settings, such as differentiating Leber's hereditary optic neuropathy from functional visual loss; monitoring neurodegenerative diseases or multiple sclerosis; and predicting visual loss in nonarteritic ischemic optic neuropathy. mGCC analysis also demonstrates high correlation with perimetry and might serve as an early structural indicator of irreversible neuronal loss. Compared to pRNFL, retinal thickness analysis of the optic nerve head demonstrates better correlation with the severity of papilledema, thus enabling its possible application in detecting raised intracranial pressure, especially in the pediatric group. Upcoming research on emerging OCT technologies including OCT-angiography, enhanced depth imaging, retinal single-layer analysis and portable systems will hopefully further enhance the utility of OCT in the field. It is crucial for neuro-ophthalmologists to be updated and familiar with these newer OCT imaging protocols and to make appropriate choices for different clinical scenarios, in order to optimize the diagnostic sensitivity and specificity.

    The sphenoid sinus, out of the facial sinuses, is certainly the most neglected as far as diagnosis is concerned. The surgical approach requires a detailed anatomical knowledge, considering the serious complications resulting from injuries of vital structures adjacent to this region. Aim: the objective of our research is to evaluate the anatomic relationship of the optic nerve with the sphenoid sinus making use of the computed tomography. Study design: series report. Material and method: the authors present a retrospective analysis of 203 computed tomographies of facial sinus belonging to individuals of both sexes aged 14 and over. The examinations were evaluated observing the course of the optic nerve, obtained through the degree of its projection on the wall of the sphenoid sinus. The method used was the modified classification of Delano, evaluating the absence of bone reduction (dehiscence) of the optic nerve in the sphenoid sinus. We analysed the degree of pneumatization of the sphenoid sinus, using Hammer's classification adapted by Guerrero, apart from the pneumatization of the anterior clinoidal process and pterigoid and the presence of the Onodi cell. Results: most of the patients (78.96%) presented their optic nerve with a type 1 course. Type 2 was observed in 16.83% of the patients, type 3 in 3.47% and type 4 in 0.74%. The presence of dehiscence of the optic nerve in the wall of the sphenoid sinus was evidenced in 21.29% of the cases. Related to pneumatization, we noticed that the pre-selar type was observed in 6.44%, the post-selar type appeared in 39.11%, the selar type appeared in 54.45%, and the apneumatized type was not observed in any of the cases. The pneumatization of the anterior clinoidal process was verified in 10.64% of the cases, while the pterigoid process was apparent in 21.29% of the cases. The Onodi cell (sphenoetmoidal) was found in 7.92% of the cases. Conclusion: the presence of dehiscence of the optic nerve is related with the

    Full Text Available AIM: To analyze the characteristics of neurological ophthalmology manifestation of patients with neurosyphilis.METHODS: Retrospective and nonrandomized case analysis were used. Totally 22 cases of 39 eyes were included. They were 17 males and 5 females, aged from 34 to 65 years old. The average age were 49.6 years old. RESULTS: The optic nerve atrophy presented in 11 cases of 22 eyes. One eye of them accompanied by left eye oculomotor nerve palsy; 5 eyes in 3 cases expressed as optic neuritis acute phase; neuroretinitis appeared in 4 cases of 6 eyes; 1 case of 2 eyes expressed as chorioretinitis accompanied by optic disc edema; central retinal artery occlusion were found in 1 case of 1 eye. Argyll-Robertson pupil was as only manifestation in 2 cases of 3 eyes. In all cases, Argyll-Robertson pupil signs can be seen in 19 eyes. Treponema pallidum particle agglutination test(TPPAwere positive in all 22 cases. Syphilis rapid plasma reactin test(RPRwere positive in 19 of 21 cases. All patients underwent lumbar puncture and cerebrospinal fluid were detected for RPR, cerebrospinal fluid protein, white blood cell count. Cerebrospinal fluid RPR were positive in 13 cases. Cerebrospinal fluid protein were greater than 450mg/L in 18 cases. Cerebrospinal fluid white blood cell count were greater than 5/mm3 in 13 cases. CONCLUSION: Neurosyphilis involving neuro-ophthalmology often occurs in middle-aged men and subacute onset. Both eyes can suffered from optic nerve disease simultaneously or sequencely. A few can be expressed as other cranial nerve palsy, which may lead to misdiagnosis. Considering medical history, clinical manifestations, ophthalmic examination, serum and cerebrospinal fluid laboratory tests can improve the diagnostic rate.

    There are five possible ocular signs or complaints of a life or sight threatening neuro-ophthalmological condition: diplopia, isolated anisocoria, transient visual loss, severe pain in head or neck (with or without photophobia) and oscillopsia/nystagmus. In this review, the ocular signs and symptoms of neuro-ophthalmological emergencies are described together with their practical work-up and the risks associated with missing the diagnosis. Concerning diplopia, the associated signs pointing to a possible threatening condition are emphasized. Six focus points resuming core messages are displayed throughout this review.

    The term fibro-osseous lesion has currently grown in popularity as an overall designation for a number of rare, histologically benign head and neck lesions that are made up of bone, fibrous tissue and cementum. Cemento-ossifying fibroma is a variant of cementifying fibroma and is a fibro-osseous disease. They are usually small innocuous lesions which follow a slow benign course and are commonly seen in the skull bone rather than the sphenoid. It is rare for these tumours to attain large size, behave aggressively, destroy bone and require a radical surgery. One such rapidly growing juvenile cemento-ossifying lesion of sphenoid in our 10-year-old young patient causing proptosis and impaired vision is reported here because of its uncommon nature and its surgical dilemma. Selection of surgical approach to resect this tumour becomes difficult because it is deeply seated and needs a multidisciplinary approach.

    This work was designed to carry out the postmortem evaluation of the potential of using a multi-angle endoscope for endonasal surgical interventions on the ethmoidal and sphenoidal sinuses. The study was performed on 5 fresh cadavers (10 sides). It was shown that the range of the angles and directions of view during dissection of ethmoidal sinuses is 10-50 degrees and 360 degrees respectively. The use of an Acclarent Cyclops endoscope made it possible to visualize all walls of the sphenoidal sinus through the enlarged aperture which confirms the higher effectiveness of this instrument compared with the traditional endoscopes having the fixed angle of view of 0, 30, 45, and 70 degrees. The disadvantages of the Acclarent Cyclops endoscope are its heavier weight and a somewhat poorer quality of the screen image of the operative field.

    Full Text Available Although a metastatic presentation of an occult prostatic adenocarcinoma is not uncommon, the majority of these patients present with bone metastasis affecting the axial skeleton. Cranial metastases to the paranasal sinuses are extremely rare. A 56-year-old man presented with loss of vision and numbness of the right side of the face. Computed tomography (CT scan and cranial magnetic resonance imaging (MRI revealed a mass invading the sphenoid sinus. The patient underwent surgery to remove the lesion, and the histopathological examination suggested metastasis of an adenocarcinoma, with positive staining to prostatic specific antigen (PSA. However, serum PSA was 4 ng/mL, and the patient did not report any lower urinary tract symptoms or bone pain. Transrectal ultrasound-guided biopsy revealed prostatic adenocarcinomas with a Gleason score of 8 [4 + 4]. The subsequent treatment consisted of radiotherapy and androgen deprivation, followed by first- and second-line chemotherapy (docetaxel and cabazitaxel when the disease progressed. The patient achieved a good response with the last cycle of cabazitaxel and after a 5-year followup is currently alive. Cranial metastases of prostate adenocarcinoma are rare, and there is currently no standard treatment for these patients. Whenever possible, surgery combined with radiotherapy and hormonotherapy is the recommended option.

    It is important to identify and maintain a midline orientation during endoscopic transsphenoidal surgery (ETSS) for sellar lesions to prevent critical injury to the internal carotid artery. Therefore, the preoperative neuroradiological assessment of the bony structures in the sphenoid sinus, including the septum attachment to the sellar floor and its surrounding structures, is essential. It has been reported that the midline filum of the sellar dura can function as a useful intraoperative orientation guide during ETSS. However, the relationship between the midline dural filum and the intrasinus bony structures, such as the sellar floor, the intrasinus septation and the ossification, remains unclear and the mechanisms underlying development of the midline dural filum have also not yet been explored. This retrospective study included 160 patients undergoing ETSS to assess both the midline dural filum and the intrasinus bony structures, using video recording reviews. The intrasinus septum and the ossification in the sphenoid sinus were evaluated on the computed tomography images of the bone window. A midline dural filum was identified in 66 (41.3%) of 160 patients. Attachment of the septum to the sellar midline was found in 61 (39.4%) of 155 patients, after excluding 5 patients with the conchal type of sphenoid sinus, 55 (90.2%) of 61 patients with a septum on the midline and only 6 (6.4%) of the remaining 94 patients without a septum on the midline had a midline dural filum. The relationship between a midline dural filum and a septum on midline was statistically significant (possification extended over the midline filum. In patients with the sellar type of sphenoid sinus, 49 (36.0%) of 136 had a midline dural filum, meanwhile, 16 (84.2%) of 19 patients with the pre-sellar type (p=0.039) and all 5 patients (100%) with the choncal type harbored a midline dural filum (possification in both the pre-sellar and the conchal type of sphenoid sinus.

    Full Text Available We report a case of a 22-year-old female student nurse who presented to hospital with an acute neuro-ophthalmological syndrome characterized by papilledema, ataxia, ophthalmoplegia and headache after a single first time use of 150 mg medroxyprogesterone intramuscular injection. Clinical, laboratory, radiological and ophthalmological investigations were in keeping with the diagnosis of idiopathic intracranial hypertension but lumbar puncture did not show a raised cerebrospinal fluid pressure suggesting a forme fruste of this entity. Her neuro-ophthalmological clinical features responded well to acetazolamide and diagnostic/ therapeutic lumbar puncture. Full recovery was achieved three months after medroxyprogesterone usage. Health care providers must be aware of this adverse drug reaction.

    Neuro-ophthalmology as a specialty is underdeveloped in India. The aim of our study was to determine the spectrum and profile of patients presenting to a tertiary eye care center with neuro-ophthalmic disorders. A retrospective hospital-based study was conducted, and records of all patients seen at the neuro-ophthalmology clinic of Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India, over a 1-year period were retrieved and evaluated. Of a total of 30,111 patients referred to various specialty clinics in a span of 1 year, 1597 (5%) were referred for neuro-ophthalmology evaluation. The mean patient age was 30.8 ± 19.5 years, with a male dominance (M:F = 2.02:1). Among these patients, optic nerve disorders were noted in 63.8% (n = 1,020), cranial nerve palsy in 7% (n = 114), cortical visual impairment in 6.5% (n = 105), and others (eye/optic nerve hypophasia, blepharospasm, and optic disc drusen) in 6% (n = 95). Among the patients with optic nerve disorders, optic neuropathy without disc edema/(traumatic optic neuropathy, hereditary, tumor-related, retrobulbar neuritis, toxic, and idiopathic) was noted in 42.8% (n = 685) and optic neuropathy with disc edema (ischemic optic neuropathy, papilledema, post-papilledema optic atrophy, papillitis, neuroretinitis, and inflammatory optic neuropathy) in 20.9% (n = 335). Sixteen percent of patients (n = 263) were incorrect referrals. The neuro-ophthalmic clinic constitutes a significant referral unit in a tertiary eye care center in India. Traumatic and ischemic optic neuropathies are the most common diagnoses. Neuro-ophthalmology requires further development as a subspecialty in India to better serve the nation's population.

    Neuro-ophthalmology focuses on the diagnosis and treatment of visual disorders related to the neurological system rather than the globe itself. Being a subspecialty of both neurology and ophthalmology, it requires specialized training and expertise in diseases of the eye, brain, nerves and muscles. Commonly encountered pathologies in neuro-ophthalmology include: optic neuropathies (such as optic neuritis and ischemic optic neuropathy), visual field loss (transient, constant, unexplained), transient visual loss, unspecified visual disturbances, diplopia, abnormal eye movements, thyroid eye disease, myasthenia gravis, anisocoria, and eyelid abnormalities. The current issue of "Harefuah" is dedicated to contemporary knowledge in neuro-opthalmology, and spans from studies of neuromyelitis optica (NMO), ischemic optic neuropathies, and optic neuropathies induced by phosphodiesterase inhibitors, to the management of sight-threatening carotid-cavernous fistulas, and more. These studies emphasize the importance of an interdisciplinary treatment team consisting of a neuro-ophthalmologist, a neuro-radiologist, and sometimes, even a neuro-surgeon. Such an approach may prove to be beneficial to the patient, by optimizing follow-up and treatment decisions. This issue emphasizes how a correct and timely diagnosis is of paramount significance in patients with neuro-ophthalmological disorders.

    Meningocele and meningoencephalocele of the lateral wall of the sphenoidal sinus (LWSS) are rare lesions, crossing the borders of multiple disciplines such as ear-nose-throat, maxillofacial, and neurologic surgery. We reviewed our surgical experience to analyze the role of the endoscopic endonasal approach and consider these pathologies from different perspectives. All consecutive cases of meningocele and meningoencephalocele of LWSS operated through an endoscopic endonasal approach from 1998 to 2015 in our institutions were collected. Medical history, focusing on previous episodes of cerebrospinal fluid leak, meningitis or seizures, was considered. The outcome was assessed considering the medical condition and the postoperative neuroimaging. The series includes 23 patients (7 male, 16 female). Mean age was 52 years (26-73 years). Eleven cases were meningoencephaloceles and 12 meningoceles. A clear cerebrospinal fluid leak occurred on in 19 patients and was associated with meningitis in 3. Two were presenting a history of epilepsy. No complications were observed, but 1 case presented seizures on waking. At follow-up (mean 84 months, 4-167) each patient is in good clinical condition with no further episodes of leaking or seizures. Endoscopic endonasal surgery is a safe and effective approach for meningocele and meningoencephalocele of LWSS; it allows resection of herniated tissue and repair of the osteodural defect. The favorable clinical outcome and the possible effectiveness on seizures lead us to support this approach as first minimally invasive treatment also in presence of epilepsy, as a first low risk epilepsy surgical procedure.

    Ectopic pituitary adenomas are exceedingly rare entities that are often misdiagnosed. The resulting delay in diagnosis may be particularly concerning in the case of Cushing syndrome caused by an ectopic adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma. Although the total resection of ectopic adenomas results in rapid and durable remission, persistent Cushing syndrome is often associated with permanently damaging invasive procedures and significantly higher risk of mortality. The authors report the case of a 48-year-old man with ACTH-dependent Cushing syndrome. On the morning before surgery, his serum cortisol measured 51 μg/dl, his ACTH level was 195.7 pg/ml, and his urinary free cortisol level was 2109 μg/day. Serum cortisol was not suppressed with the administration of high-dose dexamethasone. Imaging showed separate masses in both the sphenoid sinus and the pituitary gland, complicating the diagnostic process and requiring pathological assessment of both masses. No other abnormalities were found on thoracic, abdominal, or pelvic scans. Gross-total resection of both lesions was accomplished via an endoscopic endonasal transsphenoidal approach. Pathology confirmed an ectopic ACTH pituitary adenoma of the sphenoid sinus and a Crooke hyaline change of the pituitary gland. The patient achieved stable hormonal remission without significant postoperative complications, returned to full activity within 3 months, and remained disease free nearly 1 year after tumor resection. In a systematic literature review, the authors identified 41 cases of ectopic ACTH-secreting pituitary adenomas, including 18 arising in the sphenoid sinus without direct involvement of the sella. Including the case described here, the total number of ectopic ACTH pituitary adenomas arising in the sphenoid sinus was 19, and the total number of ectopic ACTH pituitary adenomas without regard to location was 42. For the 19 patients with adenomas found in the sphenoid sinus, ages ranged

    To evaluate correlations between longitudinal changes in neuro-ophthalmologic measures and quality of life (QOL) and disability in patients with multiple sclerosis (MS), using optical coherence tomography (OCT), visual evoked potentials (VEP), and visual field examination. Fifty-four patients with relapsing-remitting MS were enrolled in this study and underwent Multiple Sclerosis Quality of Life questionnaire (54 items) (MSQOL-54) and Expanded Disability Status Scale (EDSS) evaluation, as well as complete neuro-ophthalmologic examination including visual field testing and retinal nerve fiber layer (RNFL) measurements using Cirrus and Spectralis OCT and VEP. All patients were re-evaluated at 12, 24, and 36 months. Logistical regression was performed to analyze which measures, if any, could predict QOL. Overall, RNFL thickness results at the baseline evaluation were significantly different from those at 3 years (p ≤ 0.05), but there were no differences in functional measures (visual acuity, contrast sensitivity, color vision, visual field, and VEP). A reduced MSQOL-54 score was associated with an increase in EDSS score and a decrease in both functional and structural parameters. Patients with longer MS duration presented with a lower MSQOL-54 score (reduction in QOL). Patients with progressive axonal loss as seen in RNFL results had a lower QOL and more functional disability.

    Ectopic sphenoid sinus pituitary adenoma (ESSPA) may arise from a remnant of Rathke's pouch. These tumors are frequently misdiagnosed as other neuroendocrine or epithelial neoplasms which may develop in this site (olfactory neuroblastoma, neuroendocrine carcinoma, sinonasal undifferentiated carcinoma, paraganglioma, melanoma). Thirty-two patients with ESSPA identified in patients with normal pituitary glands (intact sella turcica) were retrospectively retrieved from the consultation files of the authors' institutions. Clinical records were reviewed with follow-up obtained. An immunohistochemical panel was performed on available material. Sixteen males and 16 females, aged 2-84 years (mean, 57.1 years), presented with chronic sinusitis, headache, obstructive symptoms, and visual field defects, although several were asymptomatic (n = 6). By definition, the tumors were centered within the sphenoid sinus and demonstrated, by imaging studies or intraoperative examination, a normal sella turcica without a concurrent pituitary adenoma. A subset of tumors showed extension into the nasal cavity (n = 5) or nasopharynx (n = 9). Mean tumor size was 3.4 cm. The majority of tumors were beneath an intact respiratory epithelium (n = 22), arranged in many different patterns (solid, packets, organoid, pseudorosette-rosette, pseudopapillary, single file, glandular, trabecular, insular). Bone involvement was frequently seen (n = 21). Secretions were present (n = 16). Necrosis was noted in 8 tumors. The tumors showed a variable cellularity, with polygonal, plasmacytoid, granular, and oncocytic tumor cells. Severe pleomorphism was uncommon (n = 5). A delicate, salt-and-pepper chromatin distribution was seen. In addition, there were intranuclear cytoplasmic inclusions (n = 25) and multinucleated tumor cells (n = 18). Mitotic figures were infrequent, with a mean of 1 per 10 HPFs and a pituitary hormones included 48% reactive for 2 or more hormones (plurihormonal), and

    Recent studies have reported that drowning victims frequently have fluid accumulation in the paranasal sinuses, most notably the maxillary and sphenoid sinuses. However, in our previous study, many non-drowning victims also had fluid accumulation in the sinuses. Therefore, we evaluated the qualitative difference in fluid accumulation between drowning and non-drowning cases in the present study. Thirty-eight drowning and 73 non-drowning cases were investigated retrospectively. The fluid volume and density of each case were calculated using a DICOM workstation. The drowning cases were compared with the non-drowning cases using the Mann–Whitney U-test because the data showed non-normal distribution. The median fluid volume was 1.82 (range 0.02–11.7) ml in the drowning cases and 0.49 (0.03–8.7) ml in the non-drowning cases, and the median fluid density was 22 (−14 to 66) and 39 (−65 to 77) HU, respectively. Both volume and density differed significantly between the drowning and non-drowning cases (p = 0.001, p = 0.0007). Regarding cut-off levels in the ROC analysis, the points on the ROC curve closest (0, 1) were 1.03 ml (sensitivity 68%, specificity 68%, PPV 53%, NPV 81%) and 27.5 HU (61%, 70%, 51%, 77%). The Youden indices were 1.03 ml and 37.8 HU (84%, 51%, 47%, 86%). When the cut-off level was set at 1.03 ml and 27.5 HU, the sensitivity was 42%, specificity 45%, PPV 29% and NPV 60%. When the cut-off level was set at 1.03 ml and 37.8 HU, sensitivity was 58%, specificity 32%, PPV 31% and NPV 59%.

    Full Text Available Abstract Neuro-Behçet’s disease (NBD involves the central nervous system; peripheral nervous system involvement is not often reported. NBD is quite common in adult patients and occurs rarely during childhood and adolescence. Young patients may share symptoms and signs of NBD with other neuro-ophthalmological disorders (e.g. idiopathic intracranial hypertension; thus, making the differential diagnosis difficult. Neuroimaging is mandatory and necessary for a correct NBD diagnosis but in children radiological examinations are often difficult to perform without sedation. From 1971 to 2011, 130 patients aged ≤16 years have been reported with NBD, according to retrospective surveys, case series, and case reports. The origin of the reported cases met the well-known geographical distribution of Behçet’s disease (BD; the mean age at presentation of neurological findings was 11.8 years, with male gender prevalence (ratio, 2.9:1. We considered in detail the neuro-ophthalmological features of the 53 cases whose neuroimaging alterations were described with an assigned radiological pattern of the disease (parenchymal: 14 cases, non-parechymal: 35 cases, and mixed: 4 cases. In 19/53 patients (36%, neuro-ophthalmological symptoms anticipated any pathognomonic sign for a BD diagnosis, or only occasional aphtae were recalled by the patients. Family history was positive in 17% of subjects. Headache was reported in 75% of the patients; in those presenting with cerebral vascular involvement, headache was combined to other symptoms of intracranial hypertension. Papilledema was the most frequently reported ophthalmological finding, followed by posterior uveitis. Treatment consisted of systemic steroids in 93% of patients, often combined with other immunosuppressive drugs (especially colchicine and azathioprine. Clinical recovery or improvement was documented in the large majority of patients. Nine subjects had definitive alterations, and one died. Based on our

    The radiological features of the main tumors and pseudotumors of the sphenoid bone with CT and MRI are described in detail. The lesions are classified as tumors and pseudotumors of the sphenoid bone and sphenoid sinus and as neighboring tumors and pseudotumors with secondary sphenoid invasion. Metastases, chondromas, fibrous dysplasia, myelomas, plasmocytomas and chordomas are the most frequent sphenoid lesions. Tumors and pseudotumors of the sphenoid sinus mainly include mucoceles and cholesterin granulomas. Neighboring tumors are of intracranial origin (pituitary adenoma, meningioma, aneurysm) or originate in the nasopharynx (nasopharyngeal fibroma, malignant tumors) or the nasosinusal cavities (inverted papillomas, invasive aspergillosis, malignant tumors). The radiological features do no always allow diagnosing the tumoral type. However, the merits of CT and, even more, of MRI for an accurate assessment of extension is indisputable.

    Objective Neuro-imaging studies are frequently ordered to investigate neuro-ophthalmic symptoms. When misused these studies are expensive and time-consuming. This study aimed to describe the type and frequency of neuro-imaging errors in patients referred to an academic neuro-ophthalmology service and to measure how frequently these neuro-imaging studies were re-interpreted. Design Prospective cohort study Participants 84 consecutive patients referred to an academic neuro-ophthalmology practice Methods From November 2009 through July 2010 we prospectively enrolled 84 consecutive new patients who had received a neuro-imaging study in the last 12 months specifically in evaluation of their presenting neuro-ophthalmic symptoms. Participants then underwent a complete neuro-ophthalmic evaluation followed by a review of prior neuro-imaging. Questions regarding appropriateness of the most recent imaging, concordance of radiological interpretation, and re-evaluation of referring diagnoses were answered by the attending physician. Main Outcome Measures 1. The frequency and types of errors committed in the utilization of neuro-imaging. 2. The frequency of re-interpretation of pre-referral neuro-imaging studies following neuro-ophthalmic history and examination. Results Most study participants (84.5%; 71/84) underwent magnetic resonance imaging (MRI) prior to referral; 15.5% (13/84) underwent only computed tomography (CT). The rate of sub-optimal neuro-imaging studies was 38.1% (32/84). The three most common reasons for sub-optimal studies were incomplete area of imaging (34.4%; 11/32), wrong study type (28.1%; 9/32), and poor image quality (21.9%; 7/32). 24 of 84 subjects (28.6%) required additional neuro-imaging. We agreed with the radiology interpretation of the prior neuro-imaging studies in the majority (77.4%; 65/84) of patients. The most common anatomic locations for discordance in interpretation were the intraorbital optic nerve (35%; 7/20) and the brainstem (20%; 4

    A retrospective cohort study of patients with tuberculum sellae meningioma (TSM)-associated sphenoidal pneumosinus dilatans (PSD) over a recent epoch was evaluated using a propensity-matched morphometric analysis. A total of 38 patients with TSM and sphenoidal PSD were identified and matched by age and sex to 32 patients without tumors (controls). Overall, no significant difference between test and control groups was noted in sphenoid sinus size or other parameters; however, significantly greater mean distances from the posterior margin of the planum sphenoidale to the diaphragma sella (0.76 ± 0.23 vs. 1.03 ± 0.27, respectively; P = 0.0001) and angle between the planum sphenoidale to anterior face of sella turcica (113.41 ± 10.58 vs. 123.21 ± 12.55, respectively; P = 0.001) were seen in patients with TSM and PSD, suggestive of a selective expansion of the tuberculum sellae region. TSM/sphenoid sinus morphologies were divided into 3 types (A, B, and C) based on the extent of tumor and sinus morphology. There was progressive increase in tumor volume and anteroposterior sinus diameter from sphenoidal PSD types A-C, which influenced selection of surgical approach. This study suggests that TSM-associated sphenoidal PSD leads to more selective splaying of the tuberculum sellae region rather than cumulative increase in sinus volume. This may lead to operative corridor expansion for endonasal access to TSM associated with sphenoidal PSD. A radiologic classification scheme for sphenoidal PSD associated with TSM is suggested that may aid surgical decision-making. Copyright © 2017 Elsevier Inc. All rights reserved.

    Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any treatment modalities related to the sphenoid sinus. To evaluate the effect of Onodi cells on the frequency of sphenoiditis. A retrospective analysis was performed in 618 adult patients who underwent high-resolution computed tomography between January 2013 and January 2015. The prevalence of Onodi cells and sphenoiditis was evaluated. Whether the presence of Onodi cells leads to an increase in the prevalence of sphenoiditis was investigated. Onodi cell positivity was observed in 326 of 618 patients and its prevalence was found to be 52.7%. In the study group, 60.3% (n=73) were ipsilaterally (n=21) or bilaterally (n=52) Onodi-positive, whereas 39.7% (n=48) were Onodi-negative (n=35) or only contralaterally Onodi-positive (n=13). Of the control group, 48.3% (n=240) were Onodi-positive and 51.7% (n=257) were Onodi negative. The co-existence of Onodi cells ipsilaterally was observed to increase the identification of sphenoiditis 1.5-fold, and this finding was statistically significant (p<0.05). The prevalence of sphenoiditis appears to be higher in patients with Onodi cells. However, it is not possible to state that Onodi cells are the single factor that causes this disease. Further studies are needed to investigate contributing factors related to sphenoiditis. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    Full Text Available The myxoid variant of chondrosarcoma is usually seen in soft tissues where it is known as chordoid sarcoma or parachordoma. Rarely, it involves bone and when it does, cranial bones are the preferred location. This tumor is frequently amalgamated with the chondroid variant of chordoma, especially when the lesion occurs in the sphenoid bone/spheno-occipital region, because of their similar clinical presentations, anatomical locations, radiological findings, and mistaken histopathological features. It is essential to distinguish myxoid chondrosarcoma from the chondroid variant of chordoma, because of the different treatment protocol and prognostic importance. We present such a location-based diagnostic dilemma, solved successfully with ancillary immunohistochemistry.

    The purpose of this study was to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). The author examined the extent and the recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus (67.9%), posterior ethmoid sinus (48.9%), frontal sinus (42.0%) and sphenoid sinus (41.4%). The characteristic features of CT images of the sinusitis were sinus opacification (22.4%), mucoperiosteal thickening (34.3%), and polyposis (2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babbel's classification. They were 1) infundibular (13.0%), 2) ostiomeatal unit (67.4%), 3)sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns (18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus, both posterior sinuses were 11.4%, 66.8%, 6.3%, respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%, 79.2%, 45.1% respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess 5.2%. The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns and the proximity of the important structures to the posterior paranasal sinuses.

    Skull base architecture is tough to understand because of its 3D complex shape and its numerous foramen, reliefs or joints. It is especially true for the sphenoid bone whom central location hinged with most of skull base components is unique. Recently, technological progress has led to develop new pedagogical tools. This way, we bought a new real-time three-dimensional insight of the sphenoid bone that could be useful for the teacher, the student and the surgeon. High-definition photography was taken all around an isolated dry skull base bone prepared with Beauchêne's technique. Pictures were then computed to provide an overview with rotation and magnification on demand. From anterior, posterior, lateral or oblique views and from in out looks, anatomical landmarks and subtleties were described step by step. Thus, the sella turcica, the optic canal, the superior orbital fissure, the sphenoid sinus, the vidian canal, pterygoid plates and all foramen were clearly placed relative to the others at each face of the sphenoid bone. In addition to be the first report of the 360 Photography tool, perspectives are promising as the development of a real-time interactive tridimensional space featuring the sphenoid bone. It allows to turn around the sphenoid bone and to better understand its own special shape, numerous foramen, neurovascular contents and anatomical relationships. This new technological tool may further apply for surgical planning and mostly for strengthening a basic anatomical knowledge firstly introduced.

    Full Text Available Mucocele é uma lesão benigna cística dos seios paranasais, apresentando crescimento lento. É composta de material mucoso ou raramente mucopurulento, ocorrendo com frequência nos seios frontal e maxilar, podendo ser múltiplas, e causar erosão óssea. As mucoceles localizadas no seio esfenoidal (MSE ou região posterior do seio etmoidal são raras, correspondendo a 1% dos casos de mucocele. Relatamos casos de MSE espontâneas submetidas a tratamento neurocirúrgico pela via transnasal transesfenoidal com uso do endoscópio.Mucoceles are benign, slowly expansive, mucous-filled cystic lesions that arise in the paranasal sinuses. They most commonly occur in the frontal and ethmoid sinuses and are rarely in the sphenoid sinus. The incidence of sphenoid sinus mucoceles is about 1% of paranasal sinus mucoceles. Almost 200 cases of sphenoidal and or intraselar mucoceles have been reported since the first description by Berg in 1889. Sphenoid sinus mucoceles result from accumulation of secretions due to obstruction of the draining sinus osteum. Clinical manifestations are dependent on the direction of the expansion toward adjacent structures, and are therefore variable. The diagnosis is based on CT and MRI. The neurosurgical treatment was marsupialization of the lesion under endoscopic vision by transseptal approach. We report two cases of sphenoidal mucoceles.

    To evaluate the MR findings of septic thrombosis of the cavernous sinus. Eleven MR images of six patients with septic cavernous sinus thrombosis obtained over a five-year period and proven clinically or radiologically were retrospectively reviewed. The contour and enhancement pattern of the cavernous sinus, changes in the internal carotid artery, orbit, pituitary gland and sphenoid sinus, and intracranial abnormalities were analyzed and compared with the findings of follow-up studies. In all six patients, contrast study revealed asymmetrical enlargement of the ipsilateral cavernous sinus and multiple irregular filling defects within it. Narrowing of the cavernous portion of the ipsilateral internal carotid artery was noted in five patients, upward displacement of the ipsilateral internal carotid artery in four, ipsilateral proptosis with engorgement of the superior ophthalmic vein in two, pituitary enlargement in five, and inflammatory change in the sphenoid sinus in six. Associated intracranial abnormalities included edema and enhancement in the meninx, temporal lobe, or pons adjacent to the cavernous sinus in four patients, hydrocephalus in one, and cerebral infarction in one. Follow-up MR imaging indicated that the extent of asymmetrical enlargement of the cavernous sinus, filling defects within it, as seen on contrast study, and enlarged pituitary glands had all decreased, without significant interval change. MR imaging is useful in the diagnosis of septic cavernous sinus thrombosis. Asymmetrical enlargement of the cavernous sinus, multiple irregular filling defect within it, as seen on contrast study, and changes in the internal carotid artery are characteristic findings.

    Recent reports have detailed common computed tomography (CT) findings in drowning victims, most notably fluid accumulation in the maxillary and sphenoidal sinuses. This CT finding could help forensic doctors to diagnose drowning. This study retrospectively investigated 151 subjects: 39 drowning and 112 non-drowning cases. Pearson's chi-square tests demonstrated that fluid accumulation in the maxillary or sphenoidal sinuses was associated significantly with drowning (p = 0.0001). The sensitivity of the drowning diagnosis was 97%, specificity was 35%, accuracy was 51%, positive predictive value was 34% and negative predictive value was 98%. Drowning was significantly associated with fluid accumulation in the maxillary and sphenoidal sinuses, but the specificity and positive predictive value of the drowning diagnosis were poor. Although the presence of fluid in the maxillary and sphenoidal sinuses cannot be used to diagnose drowning, the absence of the fluid can be used to virtually exclude drowning.

    Full Text Available Introduction: Chondroblastoma is an uncommon cartilaginous benign neoplasm, highly destructive, which specifically appears in the epiphysis of long bones in young patients. Its occurrence is extremely rare in the cranial base, normally occurring in the temporal bone. Objective: To describe a rare case in a patient presenting with a sphenoid bone chondroblastoma that invaded the middle cranial cavity, submitted to a successful surgical resection, without recurrence after 2 years. Case Report: W.J.S, 37 years old, male, forwarded to the otorhinolaryngology service with persistent and strong otalgia for 3 months. He had normal otoscopy and without visible tumorations. The computerized tomography confirmed tumor mass in the left infra-temporal cavity, invading the middle cranial cavity. The biopsy suggested giant cells tumor. After wide resection by frontal approach via orbitozygomatic osteotomy. During the surgery, we confirmed tomographic statements and didn't find temporal bone involvement. The histopathological exam confirmed chondroblastoma. After 18 months after the surgery, he doesn't present with complaints, without motor, sensitive deficits or of cranial nerves and without recurrence tomographic signals. Conclusion: The importance of differential diagnosis of chondroblastoma is remarkable in the cranial base lesions and its therapeutic approach, whose objective must always be the major possible resection with the maximum function conservation.

    2015-01-01

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    2017-11-01

    In this report, the authors present an unusual case of a 10-year-old child who suffered a severe headache and rhinorrhea that occurred as a result of fencing foil sports injury via trans-nasal-trans-sphenoidal (TNTS) pathway. Following trauma, the child had shown neurological symptoms such a pupil dilatation, change in consciousness and mild hemiparesia. Imaging demonstrated destruction of bone structures including posterior wall of sphenoid sinus and antero-superior part of sella turcica, and also a contusion at right thalamic region. For treatment of rhinorrhea lumbar drainage system (LDS) had planted in order to relieve cerebrospinal fluid (CSF) leakage. After the treatment, the patient had fully recovered without any need of further surgical intervention. CSF leakage had prevented and neurological symptoms were completely treated. This case represents the first report of brain injury via TNTS pathway in a sports practice. Diagnosis, clinic follow-up and treatment options of this rare accidental sports injury are discussed.

    Full Text Available Introduction: The osteomas are osseous lesions with slow and asymptomatic growth that most of the times is a finding in radiological exams requested for other reason. It's the most common benign neoplasm of the paranasal sinuses. The osteomas are located mainly in the frontal sinus (57% to 80%, followed by the ethmoidal sinuses (20%, maxillary sinuses and rarely in the sphenoid sinus. It has a discreet predominance in the male sex 1.5 and its incidence is higher in the 3rd and 4th decades of life. The treatment is surgical no matter the size. Objective: To describe a case of giant osteoma of the ethmoidal sinus including a brief literature review. Case Report: JDA, male, 33 years old, presented with a right constant nasal obstruction for 01 year. Upon exam, he presented with facial asymmetry with lateralization of the right ocular globe. The computed tomography of the paranasal sinuses showed a lesion with density of soft parts occupying partially the right nasal cavity, ethmoid sinus and right maxillary. The patient was submitted to surgery with full exeresis of the lesion. The anatomopathological exam confirmed osteoma. The patient evolved without evidences of the lesion recurrence. Final Comments: The osteomas in the ethmoidal sinus, irrespectively of the size and due to the risk of complications, must be operated.

    2012-12-01

    Full Text Available Thrombosis of the cerebral veins and sinuses is an infrequent cerebrovascular disorder. Because the highly variable symptoms, recent neuroimaging plays a key role in the diagnosis. Abducens nerve palsy as a focal neurological deficit is a rare clinical manifestation in these patients. We present two cases with sudden onset of diplopia and headache. Case 1: A 3-year old girl with B cell lymphoblastic leukemia developed bilateral abducens deficit and bilateral optic disc edema after treatment including L-asparaginase. Thrombosis of the right jugular vein, sagittal and right sigmoid sinuses was visualized on magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Symptoms gradually resolved after treatment with enoxiparine and MRV demonstrated recanalization.Case 2: A 75-year old female with medical history of arterial hypertension presented with headache and sudden left abduction deficit. Computerized tomography (CT scan was normal. MRI and MRV revealed aging brain and disruption of venous flow at the left internal jugular vein, suspecting thrombosis. Extracranial colour duplex sonography and CT angiography proved haemodinamic equivalent of left internal jugular vein thrombosis due to sclerotic pathology of aortic arch.Our first case illustrates the role of improved neuroimaging techniques as the best method for diagnosis of cerebral veins and sinuses thrombosis, presenting with abducens nerve palsy. With second case the potential neuroimaging pitfalls concerning the accurate diagnosis of these cerebrovascular disorders with neuro-ophthalmologic manifestation are discussed.

    2014-01-01

    Full Text Available Esthesioneuroblastoma (ENB-also known as olfactory neuroblastoma-originates primarily from the olfactory epithelium in the roof of the nasal cavity. We present here the 7 th reported case of ENB arising from the sphenoidal sinus. We undertook a review of the case notes from the time of initial presentation and literature review of this topic. A 55-year-old male presented with a 3-year history of unilateral progressive nasal obstruction, epistaxis, difficult nasal-breathing, facial pain, frontal headache and blood-tinged discharge. Nasal examination revealed a glistening mass in right nasal cavity. Endoscopy-assisted transnasal excision was performed. Histologically, tumor was identified as small round cell tumor and confirmed by immunohistochemistry to be olfactory neuroblastoma (negative leucocyte common antigen, positive neurone specific enolase. Sphenoidal ENB is rare in the literature, and this presentation is the 7 th reported case; in addition, surgical treatment is very challenging, and non-surgical treatment is used most commonly.

    2016-10-01

    Cavernous sinus thrombosis is a rare but serious complication of sphenoid aspergillosis. The rarity of this pathology makes its diagnostic very difficult on a clinical, biological and radiological sense. The authors present a case of cavernous sinus thrombosis with ipsilateral internal carotid artery thrombosis secondary to a non-invasive sphenoid aspergillosis in an immunocompetent host, responsible of a cavernous syndrome associated to a Claude Bernard Horner syndrome. One year after surgery, the patient is still asymptomatic without recurrence. Diagnostic modalities are detailed and several management of this pathology are compared. Surgery is essential in a diagnostic and therapeutic sense. There is no evidence of the interest of adjuvant therapies such as antibiotic and anticoagulation. Concerning the antifungal treatment, the attitude towards a non-invasive sphenoid aspergillosis in an immunocompetent host is unclear. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The incidence of fungal sinusitis is subjected to significant geographical variation. Basically, invasive and non-invasive fungal sinusitis is distinguished. Invasive fungal sinusitis is observed mainly in immunocompromised hosts. The diagnopsis is based on positive fungus detection combined with characteristic clinical features. The treatment of invasive fungal sinusitis is based on surgical debridement and systemic antifungal therapy. Non-invasive fungal sinusitis is either treated with surgery alone or surgery combined with systemic steroid therapy. The majority of studies showed no benefit of postoperative antimycotic medical treatment in patients with non-invasive fungal sinusitis. © Georg Thieme Verlag KG Stuttgart · New York.

    Since an accurate description on the pathophysiology of the nasal cavity and paranasal sinus (PNS) was established, a detailed evaluation of their anatomic and pathologic status, especially of the ostiomeatal unit, has become important, and computed tomography (CT) has increasingly been used for evaluating chronic sinusitis. This study was undertaken to assess the value of CT in chronic or recurrent paranasal sinusitis and to ascertain the theory of rhinogenic origin as the pathophysiologic basis of sinusitis. We retrospectively analyzed the PNS CT findings of 108 patients with chronic or recurrent sinusitis. The CT scan were obtained in thin-section (3mm or 5mm) coronal and axial planes after contrast medium administration. With respect to the location of the sinusitis, the anterior ethmoid sinus was involved in 98 (91%), maxillary sinus in 93 (86%), frontal sinus in 60 (56%), posterior ethmoid sinus in 35 (32%), and sphenoid sinus in 32 cases (30%). CT finding of the sinusitis consisted of sinus opacification (74%), mucoperiosteal thickening (69%), mucosal enhancement (36%), air-fluid level (18%), and bony wall thickening (11%). Complications included retention cysts (29%), mucoceles (8%), and orbital cellulitis (1%). Obstruction of the ostiomeatal unit was noted in 104 cases (96%), which were composed of inflammatory process, nasal polyps, concha bullosae, inverting papillomas, paradoxic middle turbinates, severe septal deviations, and large ethmoidal bulla. Of the 17 cases with a past history of Caldwell-Luc operation, 15 cases showed obstruction of the ostiomeatal units. We concluded the CT was a very useful modality for evaluating chronic or recurrent sinusitis and for demonstrating the finely detailed pathologic anatomy of the nasal cavity and paranasal sinuses.

    Full Text Available Objective. We aim to describe the first case in the literature of allergic fungal sinusitis (AFS presenting with hyperprolactinemia due to compression of the pituitary gland. Case Presentation. A 37-year-old female presented with bilateral galactorrhea and occipital headaches of several weeks. Workup revealed elevated prolactin of 94.4, negative pregnancy test, and normal thyroid function. MRI and CT demonstrated a 5.0 × 2.7 × 2.5 cm heterogeneous expansile mass in the right sphenoid sinus with no pituitary adenoma as originally suspected. Patient was placed on cabergoline for symptomatic control until definitive treatment. Results. The patient underwent right endoscopic sphenoidotomy, which revealed nasal polyps and fungal debris in the sphenoid sinus, consistent with AFS. There was bony erosion of the sella and clivus. Pathology and microbiology were consistent with allergic fungal sinusitis caused by Curvularia species. Prolactin levels normalized four weeks after surgery with resolution of symptoms. Conclusion. Functional endoscopic sinus surgery alone was able to reverse the patient’s pituitary dysfunction. To our knowledge, this is the first case of AFS presenting as hyperprolactinemia due to pituitary compression.

    We report two patients with abnormal development of the lesser wing of the sphenoid bone, globe, optic nerve and cerebral hemisphere without stigmata of neurofibromatosis type 1. The lesser wing of the sphenoid bone was abnormally formed and was not ossified ipsilateral to the dysmorphic eye and underdeveloped cerebral hemisphere. Maldevelopment of the sphenoid wing may interfere with the normal closure of the optic vesicle and normal growth of encephalic structures, possibly by disturbing developmental tissue interactions. These patients may exhibit a type of restricted primary sphenoid dysplasia, while the sphenoid dysplasia of neurofibromatosis type 1 may be secondary to orbital or ocular neurofibromas and other factors associated with that disease.

    Full Text Available Background: En plaque sphenoid wing meningioma is morphological unique in comparison with other intracranial meningiomas, characterized by a carpet-like usually small soft tissue component which invade the dura and extensively involve the bone specially the sphenoid wing and orbit causing significant hyperostosis. Patients & Methods: A retrospective analysis of the clinical data, neuro-radiological features, and operative techniques of eighteen patients underwent transcranio-orbital approach sphenoid wing meningioma presented with proptosis during the period from September 2011 to April 2014 in the neurosurgery department, Mansoura University. Patients age ranged from 38 years to 54 years and there was sex males and twelve females. Chief complaints were progressive proptosis and visual acuity deficits. All patients were operated up on using a fronto-temporal approach with orbital decompression. The extent of tumor resection and postoperative complications were investigated. Results: Total removal was achieved in fourteen cases (77.8% over a mean follow-up period of 36 months. Pathological examination showed that twelve patients (66.67% were meningothelial meningiomas. After surgery, proptosis improved in all patients, visual acuity improved in fifteen patients (83.3%. Cerebrospinal fluid leakage was found in one patient. There were no operation-related deaths or other significant complications. Four patients had residual tumor (22.2%; two of them underwent surgical re-attack of the tumor and the other two cases were sent for gamma knife radio-surgery. Conclusions: Sphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are characterized by the associated bony hyperostosis that gives them a distinct radiological appearance. The bony hyperostosis is of neoplastic nature and is responsible for many of the clinical manifestation of such tumors and hence should be totally drilled to achieve cure and avoid recurrence.

Sphenoid dysplasia is one of the characteristics of this syndrome and it occurs in 5-10% of the cases; further, abnormalities of the sphenoid wings are often considered pathognomonic. However, complete agenesis of a sphenoid wing is very rare. We report here on an unusual case of neurofibromatosis type 1 disease with the associated absence of a sphenoid wing that was diagnosed by using multidetector computed tomography.

    Ramazanova, L Sh

    2010-01-01

    Palinopsy or perseveration of a pre-seen image is impaired visual perception as preservation or repeated occurrence of a visual image of an object after its disappearance from the field of vision. Patients with palinopsy are rather frequently encountered in neurological practice; however, they may first visit an ophthalmologist in some cases. The author describes a few cases in which palinopsy was the first manifestation of cerebral arteriovenous malformation, ischemic stroke, and multiple sclerosis, as well as a case of visual perseverations while using narcotic drugs. The correct evaluation of a patient's status and the determination of the scope of additional studies are of great importance in this situation.

    2008-01-01

    Introduction Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting less than 4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, additional malaise and fever. It affects 1−5% of the adult population each year in Europe. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with clinically diagnosed acute sinusitis, and with radiologically or bacteriologically confirmed acute sinusitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides, different doses [amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides], long-course regimens), antihistamines, cephalosporins or macrolides, decongestants (xylometazoline, phenylephrine, pseudoephedrine), doxycycline, saline nasal washes, steam inhalation, and topical corticosteroids (intra-nasal).

    OBJECTIVE Exposure of the cavernous sinus is technically challenging. The most common surgical approaches use well-known variations of the standard frontotemporal craniotomy. In this paper the authors describe a novel ventral route that enters the lateral wall of the cavernous sinus through an interdural corridor that includes the removal of the greater sphenoid wing via a purely endoscopic transorbital pathway. METHODS Five human cadaveric heads (10 sides) were dissected at the Laboratory of Surgical NeuroAnatomy of the University of Barcelona. To expose the lateral wall of the cavernous sinus, a superior eyelid endoscopic transorbital approach was performed and the anterior portion of the greater sphenoid wing was removed. The meningo-orbital band was exposed as the key starting point for revealing the cavernous sinus and its contents in a minimally invasive interdural fashion. RESULTS This endoscopic transorbital approach, with partial removal of the greater sphenoid wing followed by a "natural" ventral interdural dissection of the meningo-orbital band, allowed exposure of the entire lateral wall of the cavernous sinus up to the plexiform portion of the trigeminal root and the petrous bone posteriorly and the foramen spinosum, with the middle meningeal artery, laterally. CONCLUSIONS The purely endoscopic transorbital approach through the meningo-orbital band provides a direct view of the cavernous sinus through a simple and rapid means of access. Indeed, this interdural pathway lies in the same sagittal plane as the lateral wall of the cavernous sinus. Advantages include a favorable angle of attack, minimal brain retraction, and the possibility for dissection through the interdural space without entering the neurovascular compartment of the cavernous sinus. Surgical series are needed to demonstrate any clinical advantages and disadvantages of this novel route.

    Full Text Available Background: Imaging abnormalities in the paranasal sinuses are regularly noted as incidental findings on MRI, however, little is known about their prevalence in the Iranian population. The purpose of this study was to classify these findings in the paranasal sinuses as seen on MRI and to investigate the prevalence, according to site and type of paranasal abnormality. Methods: In this cross-sectional study, the T2-weighted axial MRI of 256 patients with diseases unrelated to their paranasal sinuses were reviewed between May 2002 and June 2003. The findings were categorized according to the anatomic location and the imaging characteristics of the abnormality. The abnormalities recorded included total sinus opacification, mucoperiosteal thickening >5mm, air fluid levels and retention cysts or polyps. Unilateral or bilateral involvement and septal deviation were also noted. A sinus was considered normal if it was fully aerated and no soft-tissue density was apparent within the cavity. Results: Among our cases, 111 (43.5% were male and 145 (56.5% were female. Of these patients, abnormalities in one or more of the sinus groups were found in 110 subjects (42.9%, 55.5% of which were male and 44.5% were female (P=0.001. Maxillary sinus abnormalities were observed in 66.4% of the patients, while ethmoid sinus abnormalities were found in 63.6%. Of the ethmoid abnormalities, 21% were found in the anterior section, 9% in the middle ethmoid, and 8% in the posterior ethmoid. The most common abnormality found was mucosal thickening. Among our cases, 23.4% had septal deviation, which was significantly higher among those with sinusitis (29% versus 19.1%; P<0.01. Of those patients with sinus involvement, 16% were involved in the sphenoid sinus and 5% in the frontal sinus. The results obtained from the patients with sinus abnormality revealed that 85% suffered from cough, nasal obstruction, runny nose, facial pain and post nasal discharge and 24% had been diagnosed

    Aneurysmal bone cyst is a benign tumor that can affect all bones in the body. It rarely affects the base of the skull. It is usually located at the level of the long bones. We report the clinical case of a 44-year old man treated for a mass in the basisphenoid wrongly diagnosed as invasive prolactin-producing macroadenoma for which he was put under dopamine agonists over a period of 9 months. We adjusted the diagnosis by suggesting aneurysmal bone cyst in the sphenoid bone on the basis of its almost pathognomonic radiological aspect on MRI.

  9. Spontaneous sphenoid lateral recess cerebrospinal fluid leaks arise from intracranial hypertension, not Sternberg's canal.

    Spontaneous cerebrospinal fluid (CSF) leaks/encephaloceles are proven to be associated with intracranial hypertension by objective measurements of CSF pressure during or following endoscopic repair. A common area of involvement is a pneumatized lateral recess of the sphenoid (LRS) sinus, where prolonged intracranial pressures lead to arachnoid pits and subsequent development of skull-base defects. Even though the LRS is never present at birth, a "congenital" cause of these leaks due to a persistent Sternberg's (lateral craniopharyngeal) canal continues to be erroneously perpetuated in the literature. The objective of this study was to eliminate the myths defining these leaks as congenital in nature. Evaluation of LRS CSF leaks present within a multiinstitutional case series was performed. Data regarding demographics, body mass index (BMI), radiologic evaluation of intracranial hypertension, and direct intracranial pressure measurements (when available) were collected. Data evaluation identified 77 LRS CSF leaks in 59 patients (mean age 52 years). Obesity was present in 83% of individuals (mean BMI 36) and 81% were females. Radiologic evidence of intracranial hypertension (eg, empty sella, dilated optic nerve sheaths, and scalloped/attenuated bone) was present on 96% of preoperative computed tomography (CT) and/or magnetic resonance imaging (MRI) scans. Opening or postsurgical lumbar drain or ventriculostomy pressure measurements were elevated in 95% of patients (mean 27.7; range, 9-50 cmH2 O). This study provides objective evidence that LRS CSF leaks are secondary to erosions from intracranial hypertension and refutes the myth regarding a congenital origin from Sternberg's canal. © 2014 ARS-AAOA, LLC.

    The one-piece orbitozygomatic (OZ) approach is traditionally based on the McCarty keyhole. Here, we present the use of the sphenoid ridge keyhole and its possible advantages as a keyhole for the one-piece OZ approach. Using transillumination technique the osteology of the sphenoid ridge was examined on 20 anatomical dry skull specimens. The results were applied to one-piece OZ approaches performed on freshly frozen cadaver heads. We defined the center of the sphenoid ridge keyhole as a superficial projection on the lateral skull surface of the most anterior and thickest part of the sphenoid ridge. It was located 22 mm (standard deviation [SD], 0.22 mm) from the superior temporal line; 10.7 mm (SD, 0.08 mm) posterior and 7.1 mm (SD, 0.22 mm) inferior to the frontozygomatic suture. The sphenoid ridge burr hole provides exposure of frontal, temporal dura as well as periorbita, which is essential for the later bone cuts. There is direct access to removal of the thickest (sphenoidal) part of the orbital roof, after which the paper-thin (frontal) part of the orbital roof is easily fractured. The sphenoid ridge is an easily identifiable landmark on the lateral skull surface, located below the usual placement of the McCarty keyhole, with comparative exposure.

    This plain language summary serves as an overview in explaining sinusitis (pronounced sign-you-side-tis). The purpose of this plain language summary is to provide patients with standard language explaining their condition in an easy-to-read format. This summary applies to those 18 years of age or older with sinusitis. The summary is featured as an FAQ (frequently asked question) format. The summary addresses how to manage and treat sinusitis symptoms. Adult sinusitis is often called a sinus infection. A healthcare provider may refer to a sinus infection as rhinosinusitis (pronounced rhi-no-sign-you-side-tis). This includes the nose as well as the sinuses in the name. A sinus infection is the swelling of the sinuses and nasal cavity.The summary is based on the published 2015 "Clinical Practice Guideline: Adult Sinusitis." The evidence-based guideline includes research to support more effective diagnosis and treatment of adult sinus infections. The guideline was developed as a quality improvement opportunity for managing sinus infections by creating clear recommendations to use in medical practice. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Full Text Available Purpose: The purpose of this study was to defining the prevalence, size of incidence of different anatomical variations of the paranasal sinus (PNS and nasal cavity among Sudanese patients and efficacy of CT scan in disease determination. Introduction: Disease of the PNS is a global public health problem, with the only treatment option available being endoscopic surgery. Previous studies have suggested that anatomical variations of the PNS are common in different populations; however, there is little information available to verify this. Hence, the objective of the present study was to determine the prevalence of different anatomical variations of the PNS and nasal cavity among Sudanese patients who were referred by ear, nose, and throat (ENT surgeons for a computed tomography (CT-aided study. Methodology: The total number of patients eligible for the study was 557; of these, 51 were excluded, 317 were in the study group, and 189 were controls. The CT images were carefully reviewed and discussed with the involvement of consultant radiologists, an anatomist, and an otolaryngologist. Results: Our results showed that there was extensive pneumatization of the frontal sinus (FS in 37% of cases, a rudimentary FS in 11%, and absence of the FS in 12%. In addition, the Keros classification showed the FS to be normal in 55%, type I in 27%, type II in 10%, type III in 6%, and type IV in only 2% of patients. A large ethmoid bulla (EB was found in 43% of patients, but the remaining 57% had a normal ethmoid sinus. Posterior ethmoid cells showed extensive pneumatization unilaterally in 5%, and bilaterally in 3% of patients; 92% were normal. Extensive pneumatization of the sphenoid was seen in 49% of patients, while the remaining 51% had a normal sphenoid. The sphenoid septum was attached bilaterally to the internal carotid artery in 6% and unilaterally in 21% of patients. A septate sphenoid sinus (more than one septum was found in 33% of patients; the

    Intraosseous arachnoid cysts are rare and difficult to diagnose. The purpose of this study was to describe the clinical and radiological semiology of petrous and sphenoid arachnoid cysts and to propose a specific management strategy. This was a retrospective, descriptive study of patients with arachnoid cysts, which utilized CT, MRI, and the patients' medical histories. Ten patients were included in this study. On CT, the lesions were lytic with bony delineation. On MRI, the lesions exhibited the same signals as cerebrospinal fluid and were not enhanced after contrast. On fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted sequences, the arachnoid cysts' signal disappeared, which is a key feature for eliminating the diagnosis of cholesteatoma. Two patients underwent surgery because of misdiagnosis, either with a meningocele or a cholesteatoma. MRI FLAIR and diffusion-weighted sequences, together with osseous CT scans, help to distinguish arachnoid cysts from meningoceles and avoid unnecessary surgeries with potential complications. © 2014 Wiley Periodicals, Inc.

    AIM: Sinus X-rays are still frequently used in the evaluation of paranasal sinusitis. Many radiology departments nowadays provide the referring doctors with a single Waters' projection. Our purpose was to evaluate the diagnostic accuracy of a single Waters' view vs high resolution computed tomography (CT) in the diagnosis of paranasal sinusitis. SUBJECTS AND METHODS: A total of 134 patients with suspected paranasal sinusitis underwent a Waters' view X-ray and high resolution CT on the same day. The radiographs were evaluated independently by nine experienced radiologists, who observed each sinus separately. Sensitivity, specificity, accuracy, positive and negative predictive values were calculated for each sinus and for each observer, using the CT findings as a 'gold standard'. RESULTS: The weighted mean sensitivity for diagnosis of any abnormality in the maxillary sinus was 67.7%, specificity 87.6%, accuracy 78.6%, positive predictive value 82.5% and negative predictive value 76.9%. For this sinus the variation between observers was small, however, the sensitivity for diagnosis of any disease in the frontal and ethmoid sinuses varied widely between observers (range 1.9-54.0% and 0-58.9%, respectively). The sensitivity for the sphenoid sinus was very low (range 0-3.8%), even in radiographs which seemed to demonstrate it well. CONCLUSION: The Waters' view has its limits in the diagnosis of sinusitis of the maxillary sinuses and its contribution for diagnosing lesions in the remaining sinuses is very poor. Whenever access to CT is available, a low dose high-resolution CT study of the paranasal sinuses is highly recommended. Konen, E. (2000)

    Septic thrombosis of the cavernous sinus (STCS) is an uncommon and potentially lethal disease. Sphenoid and ethmoid sinusitis followed by facial cutaneous infections represents the most common aetiologies, with Staphylococcus aureus as the main responsible organism followed by the Streptococcus pneumoniae. Although all infectious foci of the head and neck area can potentially spread to the cavernous sinus, STCS from oral infection is an exceptionally rare occurrence. We report the unusual case of a patient who presented with an acute STCS secondary to a generalized Streptococcus milleri periodontitis. This case highlights the importance of systematically performing a detailed examination of the oral cavity in patients presenting with intracranial infections caused by uncommon pathogens such as the Streptococcus milleri group.

    Cavernous sinus thrombophlebitis (CST) is a rare and life-threatening disease without prompt diagnosis and treatment. Two cases of fulminant superior ophthalmic vein (SOV) and CST caused by maxillary periodontitis and sphenoid sinusitis are described. A 65-year-old woman presented with right proptosis, headache, and fever. A 74-year-old woman presented with left periorbital swelling. In both patients, MRI with gadolinium showed expansion of the bilateral cavernous sinus and diffuse dilatation of the SOV with non-enhancement of central thrombus, which indicated CST. The condition was complicated by brain abscess, meningitis, and ischemic stroke. These conditions were improved by antibiotic treatment, but one patient underwent exenteration of the orbit due to orbital rupture during hospitalization.

    To evaluate incidentally observed thickened mucosa of paranasal sinuses on brain MRI of patients without evidence of sinusitis. We reviewed brain MRI of 82 adults aged over 20; 45 were males and 37 were females. Brain axial MRI was obtained from the hard palate with 8mm thickness and 2mm gap. The mucosal thickness of incidentally observed paranasal sinuses seen on brain MRI was measured at the mostly thickened portion by T2- and T1-weighted images. The mean mucosal thickness at the most thickened portion of paranasal sinuses, regardless of their location was 3.5mm with S.D. of 1.5mm. The mucosal thickening was observed more commonly in maxillary (79 patients, mean 3.0mm, S.D. 1.4mm) and ethmoid sinuses (80 patients, mean 2.7mm, S.D. 1.1mm) than in sphenoid (39 patients, mean 1.6mm, S.D. 1.4mm) or frontal sinuses (38 patients, mean 1.9mm, S.D. 1.4mm). Mucosal thickening of up to 6.5mm was a common finding on brain MRI of patients without evidence of sinusitis; accuracy was 95%.

    2013-11-01

    Chronic sinusitis is a common disease that encompasses a number of syndromes that are characterized by sinonasal mucosal inflammation. Chronic sinusitis can be defined as two or more of the following symptoms lasting for more than 12 consecutive weeks: discolored rhinorrhea, postnasal drip, nasal obstruction, facial pressure or pain, or decreased sense of smell. Chronic sinusitis is further classified as chronic sinusitis with polyposis, chronic sinusitis without polyposis, or allergic fungal sinusitis using physical examination, and histologic and radiographic findings. Treatment methods for chronic sinusitis are based upon categorization of the disease and include oral and inhaled corticosteroids, nasal saline irrigations, and antibiotics in selected patients. Understanding the various forms of chronic sinusitis and managing and ruling out comorbidities are key to successful management of this common disorder.

    Maxillary sinus hypoplasia is rare, with an estimated prevalence of 1-5%. Out of the CT scans performed in sinusal patients between March 1998 and June 1999, we report on 4 isolated maxillary sinus hypoplasia, 4 maxillary sinus hypoplasia associated to concha bullosa, and 10 isolated conchae bullosas. All cases were evaluated by nasosinusal endoscopy and CT scan. Size, location and uni/bilateral presentation of concha bullosa is correlated to maxillary sinus hypoplasia presence, specially with regards to uncinate process presence, medial or lateral retraction. The pathogenesis of maxillary sinus hypoplasia is reviewed, and its relation to concha bullosa, evaluating how this could explain some cases of the so called chronic maxillary sinus atelectasia, as an acquired and progressive variant of maxillary sinus hypoplasia in adults.

    2012-01-01

    Full Text Available Endoscopic endonasal trans-sphenoid surgery (EETS is increasingly used for pituitary lesions. Pre-operative CT and MRI scans and peroperative endoscopic visualization can provide useful anatomical information. EETS is indicated in sellar, suprasellar, intraventricular, retro-infundibular, and invasive tumors. Recurrent and residual lesions, pituitary apoplexy and empty sella syndrome can be managed by EETS. Modern neuronavigation techniques, ultrasonic aspirators, ultrasonic bone curette can add to the safety. The binostril approach provides a wider working area. High definition camera is much superior to three-chip camera. Most of the recent reports favor EETS in terms of safety, quality of life and tumor resection, hospital stay, better endocrinological, and visual outcome as compared to the microscopic technique. Nasal symptoms, blood loss, operating time are less in EETS. Various naso-septal flaps and other techniques of CSF leak repair could help reduce complications. Complications can be further reduced after achieving the learning curve, good understanding of limitations with proper patient selection. Use of neuronavigation, proper post-operative care of endocrine function, establishing pituitary center of excellence and more focused residency and endoscopic fellowship training could improve results. The faster and safe transition from microscopic to EETS can be done by the team concept of neurosurgeon/otolaryngologist, attending hands on cadaveric dissection, practice on models, and observation of live surgeries. Conversion to a microscopic or endoscopic-assisted approach may be required in selected patients. Multi-modality treatment could be required in giant and invasive tumors. EETS appears to be a better surgical option in most pituitary adenoma.

    To evaluate the utility of computed tomography (CT) as the technique of choice in the diagnosis and study of the extension of paranasal sinus mucoceles and to assess the role of magnetic resonance (MR) imaging. We carried out a retrospective study of 57 paranasal sinus mucoceles in 56 patients who had been diagnosed and treated from 1977 to 1997. Forth-eight patients had been examined by CT and, of these, six had also undergone MR imaging. Eight patients had only plain X-rays. Most of the mucoceles (73,2%) were located in frontal or frontal-ethmoidal sinus, followed by maxillary sinus (21.5%), the sphenoid sinus was the least frequent sites (5.3%). Of the 49 mucoceles (bilateral in one case) diagnosed by CT, 27 (56.25%) presented expansion and bone destruction, 16 (33,3%) showed only expansion and 6(12%) showed no clear evidence of expansion. Thirty extended to the orbit, four to the endocranium, two to the soft tissues of the forehead and one to the pterygomaxillary fissure and the sphenoidal ridge in one, involvement of both orbits in two and pyomucocele in another. The CT findings were characteristic in nearly every case: well-defined mass, low attenuation (high attenuation when the secretions were very thick), expansive and unenhanced by contrast agents. CT is the technique of choice for the diagnosis of mucocele and to assess their extension and the degree of bone involvement. The utilization of MR imaging facilities the definition of the interface between intracranial and intraorbital structures. (Author) 25 refs.

  14. [Re-evaluation of using acupuncture needle as sphenoidal electrode in temporal lobe epilepsy].

    Chu, Nai-Shin

    2009-06-01

    In 1965, Feng of the Peking Union Hospital published an article entitled "Innovation in electroencephalography: the use of acupuncture needles as sphenoidal electrodes". It was a preliminary report, but surprisingly EEG records in the figures did not show definite spikes or sharp waves in the sphenoidal leads. In 1983, Feng and his colleagues reported a summary of 2,000 cases studied with acupuncture needle sphenoidal electrodes. This time, spikes or sharp waves were shown in EEG recordings. However, cases studied were several "paroxysmal disorders", including psychomotor seizure (155 cases), generalized seizure (765 cases), epileptic cephalgia (101 cases), syncope (104 cases), abdominal epilepsy (24 cases), encephalopathy (135 cases), brain tumor (32 cases), hemiplegia of unknown cause (43 cases), psychosis (34 cases), and others (607 cases). Therefore, there were many unknown cases and many cases that were not related to temporal lobe epilepsy. Surprisingly, the increase in detection by acupuncture needle electrode was higher for hemiplegia of unknown cause, brain tumors, and encephalopathies than for the temporal lobe epilepsy. Furthermore, the issue of no insulation of the acupuncture needle was not addressed. Therefore, we began in 1988 to reinvestigate the usefulness of uninsulated acupuncture needles as sphenoidal electrodes. We also compared the efficacy of anterior temporal electrodes (T1, T2) with those of acupuncture needle and EMG needle. Our results showed that when compared to the routine EEG recordings, acupuncture needle sphenoidal electrodes increased the yield of detecting anterior temporal spikes from 41% to 70%. Our data further showed that when compared to the EMG needle recordings, acupuncture needle recordings had the same detection rate, but the spike amplitude was slightly smaller (129 microv vs. 135 microv). Interestingly, we also found that anterior temporal surface electrode recordings were nearly as good as those of acupuncture needle

  15. Ophthalmic complications of endoscopic sinus surgery

    Directory of Open Access Journals (Sweden)

    Malgorzata Seredyka-Burduk

    Full Text Available Abstract Introduction: The proximity of the paranasal sinuses to the orbit and its contents allows the occurence of injuries in both primary or revision surgery. The majority of orbital complications are minor. The major complications are seen in 0.01-2.25% and some of them can be serious, leading to permanent dysfunction. Objective: The aim of this study was to determine the risk and type of ophthalmic complications among patients operated due to a chronic rhinosinusitis. Methods: This is a retrospective study of 1658 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with or without polyps or mucocele. Surgeries were performed under general anesthesia in all cases and consisted of polyps' removal, followed by middle metal antrostomy, partial or complete ethmoidectomy, frontal recess surgery and sphenoid surgery if necessary. The ophthalmic complications were classified according to type, frequency and clinical findings. Results: In our material 32.68% of the patients required revision surgery and only 10.1% had been previously operated in our Department. Overall complications occurred in 11 patients (0.66%. Minor complications were observed in 5 patients (0.3% with the most frequent being periorbital ecchymosis with or without emphysema. Major complications were observed in one patient (0.06% and were related to a lacrimal duct injury. Severe complications occurred in 5 cases (0.3%, with 2 cases and referred to a retroorbital hematoma, optic nerve injury (2 cases and one case of extraocular muscle injury. Conclusions: Orbital complications of endoscopic nasal surgery are rare. The incidence of serious complications, causing permanent disabilities is less than 0.3%. The most important parameters responsible for complications are extension of the disease, previous endoscopic surgery and coexisting anticoagulant treatment.

    The detailed radiological study of the anatomy of the nasal cavities and paranasal sinus is essential prior to endoscopic sinus surgery since, on the one hand, it discloses the extent of the disease and, on the other hand, it aids in the detection of the numerous anatomic variants, some of which are of great interest to the endoscopic as the lack of preoperative knowledge of them may increase the risk of complications. the objective of the present report is to review these variants, stressing those that may be associated with a greater surgical risk. Although coronal computed tomography is the technique of choice for pre endoscopy examination, certain structures and anatomic variants are better viewed in axial images. These exceptions include anterior and posterior walls of the frontal sinuses, the anatomic relationships between posterior ethmoid complex and the sphenoid sinus, the relationships between the sphenoid sinus and the optic nerve, and the detection of Onodi cells. Thus, we recommend that the radiological examination include both coronal and axial images. (Author) 16 refs.

    Full Text Available Mycetoma is a chronic suppurative infection involving the skin, subcutaneous tissue and bone. The hallmark of mycetoma is tumefaction, draining sinuses and the presence of microcolonies called grains. Sinuses develop in all patients with mycetoma within a year of the appearance of the lesion. The following case is reported as no sinuses had developed despite the presence of the lesion for 9 years, posing a diagnostic dilemma.

    2014-01-01

    Full Text Available Sinonasal actinomycosis should be suspected when a patient with chronic sinusitis does not respond to medical therapy or has a history of facial trauma, dental disease, cancer, immunodeficiency, long-term steroid therapy, diabetes, or malnutrition. Radiological evaluation with computed tomography and magnetic resonance imaging are important in differential diagnosis, evaluating the extent of disease, and understanding clinical symptoms. Endoscopic sinus surgery associated with long-term intravenous antibiotic therapy is the gold standard for treatment of sinonasal actinomycosis. We report an unusual case of abducens nerve palsy resulting from invasive sinonasal actinomycosis in a patient with an abnormally enlarged sphenoid sinus. A review of the current literature highlighting clinical presentation, radiological findings, and treatment of this uncommon complication is also presented.

    Mast cell tumors are found in most organs and tissues with variable biologic behavior in dogs. This case illustrates the clinical and magnetic resonance imaging (MRI) findings in a dog with disseminated mast cell tumor infiltrating the sphenoid bones. A 6-year-old male neutered Greyhound presented with a 3-day history of acute onset of blindness. General physical examination was normal. Neurological examination revealed mildly disorientated mental status, absent menace response in both eyes, bilaterally decreased vestibulo-oculocephalic reflexes and absent direct and consensual pupillary light reflex in both eyes. An electroretinogram indicated normal retinal function in both eyes. A lesion involving the middle and rostral cranial fossa was suspected. Hematology and serum biochemistry were normal except decreased urea (1.2 mmol/L). MRI of the head revealed heterogeneous signal intensity of the sphenoid bones on T2-weighted images and loss of their normal internal architecture. Cerebrospinal fluid analysis was normal. Abdominal ultrasound revealed hepatosplenomegaly and mesenteric lymphadenopathy. Fine needle aspirates were taken from the jejunal lymph nodes and the spleen. Results were consistent with disseminated mast cell tumor. The owner declined any treatment and the dog was euthanatized. Postmortem examination confirmed disseminated mast cell tumor affecting multiple organs, including the sphenoid bones. To our knowledge, this is the first case describing MRI features of disseminated mast cell tumor affecting the sphenoid bones and causing acute onset of blindness in a dog.

    To report the first case of bilateral cavernous sinus thromboses and bilateral intraorbital abscesses secondary to Streptococcus milleri. Single interventional case report. The findings of the ophthalmic evaluation, radiographic imaging, medical and surgical intervention, specimen cultures, and clinical course were analyzed. A 17-year-old female had bilateral proptosis, decreased vision in the left eye, and altered mental status at presentation. An orbital compartment syndrome developed in the left eye and purulent material was present after lateral canthotomy, suggestive of an intraorbital abscess. Magnetic resonance imaging (MRI) scans revealed bilateral cavernous sinus thromboses, and subsequent computed tomographic (CT) scans revealed bilateral intraorbital abscesses in the setting of acute ethmoid and sphenoid sinusitis. Antibiotic treatment and surgical drainage of the orbital abscess and sinuses was performed, and specimen cultures revealed S. milleri. After surgery, the patient experienced hearing loss and a right internal capsule infarct, in addition to complete vision loss in the left eye. A second intraorbital abscess developed in the right eye and was drained surgically. The vision remained 20/20. Streptococcus milleri is a virulent organism with a propensity to form abscesses in multiple areas of the body and should be considered as a possible etiologic agent in abscess formation of the orbit and cavernous sinus thrombosis.

    Objective: To determine the CT and MR imaging features of ossifying fibroma with aneurysmal bone cyst of the paranasal sinus. Materials and methods: We retrospectively reviewed 15 patients with histopathology-proven ossifying fibromas with aneurysmal bone cysts in the paranasal sinus. All 15 patients underwent CT and MR imaging. The following imaging features were reviewed: location, shape, margin, CT findings, and MR imaging appearances and time-intensity curve of dynamic contrast-enhanced MR imaging. Results: Ossifying fibromas occurred in the maxillary sinus in one patient, sphenoid sinus in 2, frontal sinus in 3, frontoethmoid sinuses in 3, and ethmoid sinus in 6 patients. Ossifying fibromas showed an elliptic-shape and aneurysmal bone cysts revealed a multicystic appearance, with well-demarcated margins. On unenhanced CT, ossifying fibromas appeared isodense to gray matter with scattered calcifications in nine, ground-glass appearance in 6 patients and aneurysmal bone cysts showed mixed density. Ossifying fibromas appeared isointense to gray matter in 12 and slightly hypointense in three patients on T1-weighted images, and isointense in 4 and hypointense in eleven patients on T2-weighted images, with moderate or marked enhancement after administration of contrast material. The time-intensity curves of eight ossifying fibromas exhibited a rapidly enhancing and rapid washout pattern. The intracystic components of aneurysmal bone cysts showed heterogeneous signal intensity on MR images, with fluid-fluid levels identified clearly by T2-weighted images, without enhancement. The periphery and septa of aneurysmal bone cysts appeared isointense on MR images, with marked enhancement. Conclusions: Fluid-fluid levels within an elliptic-shape mass with scattered calcifications or ground-glass appearance is highly suggestive of this complicated entity in the paranasal sinus.

    Full Text Available Neurofibromatosis (NF with sphenoid wing dysplasia is a rare clinical entity. Herewith, we present a case of NF with sphenoid wing dysplasia which presented with pulsatile progressive proptosis. Other ocular symptoms or visual disturbances were absent. Diagnosis of the condition was not easy and the management was a challenging task which needed multidisciplinary approach as there were ocular, neurological, orthopedic, and dermatological manifestations. With neurosurgical intervention, reconstruction of the sphenoid wing was possible. Proptosis was corrected without any disturbance of vision.

    A primary intraosseous cavernous hemangioma located at the sphenoid bone with extensive involvement of the orbital roof and the lateral wall of the orbit is very rare. A 48-year-old woman presented with progressive right exophthalmos and diplopia. CT showed a bony mass lesion in the right sphenoid bone extending to the orbital bone. MRI showed an abnormal lesion in the sphenoid bone, which was heterogeneously enhanced with gadolinium. All of the abnormal bone was surgically removed, and histological examination confirmed a cavernous angioma. We also present a brief clinical and radiological review of seven previously reported cases.

    Feng, Y K; Hsu, C C; Kuo, T H

    1981-01-01

    This paper describes the use of acupuncture needles as sphenoidal electrodes in the EEG studies of 648 patients. Among 87 cases of suspected psychomotor epilepsy, as compared with conventional electrodes, use of the improved sphenoidal electrodes could raise the incidence of abnormal findings by 25%. Among 327 cases of generalised epilepsy they raise the incidence of abnormalities by 3% only but they were helpful in the differentiation between primary and secondary epilepsy. In 129 cases of non-convulsive disorders the improved sphenoidal electrodes helped in giving a more definite diagnosis in brain tumours, organic encephalopathies, psychoses, hemiplegias of unknown cause, syncope, epileptic cephalgia, vertigo and abdominal epilepsy. Our 17 years experience has shown that the use of acupuncture needles as sphenoidal electrodes is simple, safe, reliable and good for routine use.

    The aim of this study was to evaluate the frequency of anatomical variation in nasal cavity and paranasal sinuses by comparing a unilateral cleft lip and palate (UCLP) group with a non-syndromic control group using cone beam computed tomography (CBCT). This study included 24 UCLP patients in the UCLP group and 24 non-syndromic patients in the control group. Coronal CBCT images were taken in all patients and were evaluated for anatomical variation. The measurements obtained in this study were analysed using chi-square and Fisher's exact tests to compare the two groups statistically. In the UCLP group, there were statistically lower frequencies of pterygoid process pneumatisation (p<0.05), higher wing pneumatisation (p<0.05), and sphenoid sinus over pneumatisation (p<0.05), and statistically higher frequencies of anterior nasal septal deviation (p<0.05) compared to the control group. A higher incidence of anterior nasal septal deviation was found in UCLP patients compared to the patients in the control group. It is likely that for this reason, UCLP patients might be predisposed to sinusitis. In UCLP patients, the incidence of neurovascular structures in the sphenoid sinus was lower than that in non-syndromic control patients (Tab. 1, Fig. 6, Ref. 33).

    An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case. (orig.)

    2014-08-01

    BACKGROUNd: We report a case of allergic fungal sinusitis (AFS) involving the lacrimal sac and review the current English literature. A literature search for AFS involving the lacrimal sac revealed two reports with only one of the two cases demonstrating histological evidence of fungal elements. This is just the third such case and only the second reported case with histopathologic confirmation of fungal elements by Gomori methenamine silver (GMS) stain. A PubMed database search was performed using combinations of the following key words: allergic fungal sinusitis, lacrimal sac, nasolacrimal duct, ophthalmology, epiphora, orbit. A 70-year-old white man with a history of chronic conjunctivitis and nasal polyps presenting with chronic epiphora was found to have dacryostenosis on the left side. A CT scan of the orbits revealed mucoperiosteal thickening completely obliterating the frontal, ethmoid and sphenoid sinuses. A left external dacryocystorhinostomy (DCR) was performed and the lacrimal sac contents were studied histopathologically. Microscopic examination of the lacrimal sac contents disclosed allergic mucin with laminated aggregates of eosinophils in various stages of degeneration, Charcot-Leyden crystals and rare noninvasive fungal hyphae confirming the diagnosis of AFS. Fungal elements stained positively with Gomori methenamine silver stain. Although rarely reported, AFS can affect the lacrimal sac. AFS should be suspected in patients with a history of recurrent refractory sinusitis, recurrent dacryocystitis and nasal polyposis. Early diagnosis is important for adequate treatment and prevention of recurrence.

    Adhesion formation and ostial stenosis are common causes of surgical failure after endoscopic sinus surgery (ESS). Postoperative topical steroid application has been shown to improve wound healing. Chitosan-dextran gel (CD gel) is an effective hemostatic nasal dressing. This study aims to determine the effect of the addition of budesonide to CD gel on postoperative ostial stenosis and adhesion formation following ESS. This prospective, blinded, randomized controlled trial was conducted between October 2012 and April 2015. Thirty-six patients over 18 years undergoing ESS were randomized to receive either: no treatment, CD gel, CD gel with 1 mg/ 2 mL budesonide, or topical steroid cream to their left or right sinuses (different treatment each side). Each sinus ostium and endoscopic features of wound healing was measured intraoperation, and 2 weeks, 3 months, and 12 months postoperation. Data was analyzed using the analysis of variance (ANOVA) and post hoc Tukey honestly significant difference (HSD) tests. There was a significant reduction in stenosis within all 3 sinuses ostia sites when CD + budesonide was compared to control, with the greatest effect seen at 12 months: The mean ± standard deviation (SD) percentage of baseline areas at 12 months were 76% ± 6.2% vs 37% ± 23.5%, 76% ± 6.3% vs 52% ± 4.9%, and 83% ± 6.5% vs 58% ± 5.0% (all p < 0.05), for CD + budesonide compared to control in the frontal, sphenoid, and maxillary sinuses, respectively. The incidence of adhesions was 4% in the CD + budesonide group compared to 15% in the control group. This study has shown that CD gel, when combined with topical budesonide solution, improves long-term sinus ostial patency and prevents ostial stenosis post-ESS. © 2017 ARS-AAOA, LLC.

    Nasal tuberculosis is very rare but much rarer is tuberculosis of paranasal sinuses. It involves especially the maxillary sinus and is usually unilateral. We report an unusual case of tuberculosis of frontal and maxillary sinus in a 68 years old male, who presented with a swelling above left medial canthus, with no other eye or nasal complaints. Clinical and radiological findings on our initial evaluation suggested that the patient had left frontal mucocoele with bilateral maxillary haziness. Diagnosis was established on FNAC report and subsequent Ziehl - Neelsen staining of nasal swabs and tuberculin skin test. Later chest x-ray examination was suggestive of pulmonary tuberculosis, which was the primary cause. Patient responded well to antituberculosis drug therapy.

  4. Maxillary sinus augmentation

    Full Text Available Placing dental implants in the maxillary posterior region can be both challenging and un-nerving for a regular implant dentist who is not well versed with advanced surgical procedures. It is vital for a general dentist to understand the fundamentals of bone grafting the maxillary sinus if he/she is really committed to providing the best health care for their patients. The dental practice is seeing an increasing group of patients who are living longer, and this group of older baby boomers often has an edentulous posterior maxilla either unilateral or bilateral. When edentulous, the posterior maxilla more likely has diminished bone height, which does not allow for the placement of dental implants without creating additional bone. Through grafting the maxillary sinus, bone of ideal quality can be created (allowing for placement of dental implants, which offer many advantages over other tooth replacement modalities. The sinus graft offers the dental patient a predictable procedure of regenerating lost osseous structure in the posterior maxilla. This offers the patient many advantages for long-term success. If dentists understand these concepts, they can better educate their patients and guide them to have the procedure performed. This article outlines bone grafting of the maxillary sinus for the purpose of placing dental implants. This review will help the readers to understand the intricacies of sinus augmentation. They can relate their patient's condition with the available literature and chalk out the best treatment plan for the patient, especially by using indirect sinus augmentation procedures which are less invasive and highly successful if done using prescribed technique.

    1980-06-01

    A case report and discussion of cutaneous odontogenic sinus tracts, frequently encountered but often misdiagnosed and mistreated, are presented. Awareness that periapical dental abscesses are the most common etiologic factor of cutaneous sinus tracts involving the face and neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. These lesions are often misinterpreted as chronic, resistant to therapy, pyogenic nodules, or granulomas. A high degree of suspicion is required for making the correct diagnosis, and dental roentgenographic studies should routinely be obtained in all such lesions. Permanent healing cannot be achieved unless the original site of infection is located and eradicated.

    Vossough, Arastoo; Vorona, Gregory A.; Beslow, Lauren A.; Ichord, Rebecca N.; Licht, Daniel J.

    2015-01-01

    Objective: To describe clinical characteristics, imaging findings, morbidity, and mortality in a single-center cohort of 12 pediatric cavernous sinus thrombosis cases and to review all cases available in recent English literature. Methods: Clinical data and radiographic studies on 12 cases from our institution were analyzed retrospectively. A literature search and review was conducted, with additional cases pooled with the new cohort for an aggregate analysis. Results: Twelve cases of cavernous sinus thrombosis in children from the Children's Hospital of Philadelphia between January 1, 2000, and December 31, 2013, were reviewed. All patients survived to discharge; 3 of 12 (25%) experienced neurologic morbidity. Contrast-enhanced MRI and contrast-enhanced head CT were 100% sensitive for detecting cavernous sinus thrombosis, while noncontrast time-of-flight magnetic resonance venography (TOF MRV) and noncontrast head CT were 0% sensitive. Literature review produced an additional 40 cases, and the aggregate mortality rate was 4 of 52 (8%) and morbidity rate was 10 of 40 (25%). Outcomes did not vary by treatment or with unilateral vs bilateral cavernous sinus involvement. There was a trend toward worse outcomes with fungal infections. Conclusion: Our case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed. PMID:26231260

  13. A simultaneous comparison of acupuncture needle and insulated needle sphenoidal electrodes for detection of anterior temporal spikes.

    Science.gov (United States)

    Chu, N S

    1992-01-01

    Uninsulated acupuncture needles have been used as sphenoidal electrodes, but the issue of insulation has not been adequately addressed. In this report, acupuncture needles and insulated needle sphenoidal electrodes were simultaneously used to compare the rate of spike detection, spike amplitude and distribution of maximal spikes from eight spike foci in seven patients with temporal lobe epilepsy. When compared to the insulated needle electrode, the acupuncture needle electrode was equally effective in spike detection, but spike amplitudes tended to be smaller and maximal spikes were less frequently encountered. Thus, insulation has an influence on the spikes recorded by the acupuncture needle sphenoidal electrode. However, the overall effect appears to be not sufficiently different from the insulated needle electrode for the purpose of detecting anterior temporal spikes in outpatient EEG recordings for the diagnosis of temporal lobe epilepsy.

  14. Endovascular angioplasty before resection of a sphenoidal meningioma with vascular encasement.

    Science.gov (United States)

    Chivoret, N; Fontaine, D; Lachaud, S; Chau, Y; Sedat, J

    2011-09-01

    We describe a case of sphenoid wing meningioma presenting with cerebral infarction due to extended vascular encasement in which endovascular angioplasty was performed before surgery to avoid perioperative ischemia. A severe stenosis involved the intracranial internal carotid artery and the proximal segments of the middle and anterior cerebral arteries. Endovascular dilatation was followed by complete surgical resection. Preoperative mild aphasia and hemiparesia resolved completely after surgery. Endovascular angioplasty of arterial trunks and their branches can be proposed before the resection of skull base meningiomas encasing these arteries to decrease the risk of perioperative brain ischemia related to their surgical manipulation or vasospasm.

    Prevalence of sinusitis on sinus computed tomography (CT) in asthmatic patients and efficacy of intranasal corticosteroid treatment on asthmatic symptoms in asthmatic patients with rhinosinusitis on sinus CT is unclear. Sinus CT of asthmatic patients were evaluated using the Lund-Mackay system (LMS). Intranasal corticosteroid treatment (mometasone furoate) was newly added to symptomatic asthmatic patients with rhinosinusitis treated without intranasal corticosteroids, and the findings of the Asthma Control Test (ACT), Asthma Control Questionnaire in 5 items (ACQ5), spirometry, and sinus CT were evaluated before and 3 months after additional intranasal corticosteroid treatment. In a total of 160 asthmatic patients, rhinosinusitis and maxillary, ethmoidal, sphenoidal, and frontal sinusitis were observed in 75.0%, 70.0%, 53.1%, 33.1%, and 28.8%, respectively. Nasal symptoms and rhinophonia were observed in 81.9% and 72.5%, respectively, and patients with nasal symptoms and those with rhinophonia both showed significantly higher LMS scores in each sinus. Chronic rhinosinusitis (CRS) was observed in 66.9%, and these patients had significantly more severe asthma than the patients without CRS. In patients with CRS, patients with rhinophonia showed significantly higher LMS scores than those without rhinophonia. ACT, ACQ5, and the value of the forced expiratory volume in 1 second (FEV1) all significantly improved 3 months after the additive intranasal corticosteroid treatment in 24 patients, despite the fact that their LMS scores remained unchanged. Additive intranasal corticosteroid treatment may be an effective treatment option for symptomatic asthmatic patients with rhinosinusitis. © 2015 ARS-AAOA, LLC.

    Full Text Available Background: Endoscopic sinus surgery has been used for diagnosis and treatment of chronic inflammatory diseases of paranasal sinuses since recent years. Materials and Methods: In this study 104 patients with chronic sinusitis (with or without polyps which were managed with endoscopic sinus surgery (ESS were followed for 6 to 24 months after surgery (24 patients refused to continue follow up and the recovery rate of symptoms were evaluated. Results: The effectiveness of this therapy is statistically approved and the most important symptom which diminished was nasal obstruction (from 95 percent to 18.5 percent, the least important symptom which diminished was anosmia (from 57 percent to 21 percent. Conclusion: This study confirmed the efficacy of functional endoscopic sinus surgery in improvement of chronic sinusitis symptoms.

    Purpose: Misdiagnosis of 'sinusitis' is still frequent in children, although mucosal swelling in the paranasal sinuses of children has been reported as a common incidental finding. Recent radiological publications on the problem are rare. We prospectively evaluated the mucosal thickening in the paranasal sinuses and mastoid cells of children who underwent MRI of the head for reasons other than sinusitis or mastoiditis. Materials and Methods: 147 patients, 0.2 - 22.7 years, median 8.9. Axial and sagittal T2 TSE images were evaluated by two experienced pediatric radiologists. Categories for the degree of mucosal swelling were for the maxillary, frontal and sphenoid sinuses: no swelling, minor: < 5 mm, or major: {>=} 5 mm; for ethmoid cells and mastoid cells: not present, minor: {<=} 50 % of cells, or major: > 50 %. Results: 61 % of children had one or more salient findings in their paranasal sinuses or mastoid cells. 48 % had mucosal swelling in their paranasal cavities, 25 % in their mastoid cells. The prevalence was higher among children less than 10 years of age (60 % and 42 %) and among children with current upper respiratory tract infection (71 % and 35 %). There was no correlation to a history of headache, snoring, asthma and allergies, or to gender or place of residence. Conclusion: Mucosal swelling in paranasal sinuses and in mastoid cells is a frequent incidental finding in children. Even major mucosal swelling in a paranasal sinus is not necessarily a sign of infection. In radiological reports the terms 'sinusitis' and 'mastoiditis' should therefore be used with great caution. The initiation of treatment should be based on clinical symptoms and not on radiological abnormalities alone. (orig.)

    We assessed the morphological and radiological characteristics of ethmomaxillary sinus (EMS), which is an enlarged posterior ethmoidal air cell occupying the superior portion of the maxillary sinus while draining into superior meatus. This study is based on 1450 patients submitted to CT examination of the paranasal sinuses between 1998 and 2002. Sequential CT scans were obtained in the coronal plane in all the patients with 2.5- to 5-mm section thickness and were evaluated for EMS. The diagnosis of EMS was made when there was a posterior ethmoidal cell occupying the superior part of the maxillary sinus while draining to the superior meatus. When EMS was diagnosed, the morphology of the septum between the and maxillary sinus, and width of the superior meatus, were noted. The EMS was found in 10 of 1450 (0.7%) patients. The coexisting anatomic variations were concha bullosa (50%), upper concha pneumatization (20%), maxillary sinus hypoplasia (20%), uncinate bulla (10%), hypertrophied inferior concha (10%), paradoxic middle concha (10%), and septate maxillary sinus (10%). There was no relation between EMS and sinus disease. The EMS is a rare anatomic variation and does not appear to be associated with sinusitis. The EMS is not a well-studied anatomic variation, and the literature is lacking adequate information about this anatomic variation. This study performed in a large series of patients will possibly contribute to better understanding of this particular anomaly. (orig.)

    Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation.

    "Headache and fever" is a common presentation to the urgent care and emergency department setting and can have many etiologies. We present a case of a 10-year-old girl who presented with headache and fever and was found to have intracranial extension of sinusitis despite lack of typical sinus or chronic upper respiratory tract infection symptoms. This case illustrates the need in the emergency department or urgent care to keep a broad differential diagnosis for pediatric headache, especially when initial interventions are unsuccessful. We also review the epidemiology of pediatric sinusitis, age at sinus development, and associated intracranial complications.

    Progressive multifocal leukoencephalopathy (PML) is a severe often fatal opportunistic infection of the central nervous system caused by reactivation of a ubiquitous polyoma virus, JC virus. Although typically characterized by multifocal asymmetric subcortical white matter lesions, it may be monofocal and affect the cortical gray matter. Among the broad spectrum of clinical manifestations that occurs with PML, visual complaints are common. Combination of representative personally observed cases of PML and comprehensive review of case series of PML from 1958 through 2014. Neuro-ophthalmic signs and symptoms were reported in approximately 20%-50% of patients with PML and can be the presenting manifestation in half of these. A majority of these presentations occur from damage to cerebral visual pathways resulting in visual field defects, cortical blindness, and other disorders of visual association. Given the decreased frequency of infratentorial and cerebellar involvement, ocular motility disorders are less common. Visual complaints occur in patients with PML and are often the presenting sign. Awareness of this condition is helpful in avoiding unnecessary delays in the diagnosis of PML and management of the underlying condition. Recent guidelines have established criteria for diagnosis of PML in the high-risk patient population and strategies to mitigate the risk in these populations.

  7. Neuro-Ophthalmology: Transitioning From Old to New Models of Health Care Delivery.

    Science.gov (United States)

    Frohman, Larry P

    2017-06-01

    In contradiction to fundamental laws of supply and demand, 2 decades of payment policies have led to some medical specialties experiencing declines in both manpower and reimbursement. This paradox has resulted in increasingly long wait times to see some specialists, some specialties becoming less attractive to potential trainees, and a dearth of new trainees entering these fields. Evolving models of health care delivery hold the promise of increasing patient access to most providers and may diminish costs and improve outcomes for most patients/conditions. However, patients who need care in understaffed fields may, in the future, be unable to quickly access a specialist with the requisite expertise. Impeding the sickest and most complex patients from seeing physicians with appropriate expertise may lead to increased costs and deleterious outcomes-consequences contrary to the goals of health care reform. To ensure appropriate access for these patients requires 2 conditions: 1. Compensation models that do not discourage trainees from pursuing nonprocedural specialties, and 2. A care delivery model that expediently identifies and routes these patients to the appropriate specialist.

  8. Abnormal head oscillations in neuro-ophthalmology and neuro-otology

    Shaikh, Aasef G.

    2016-01-01

    Purpose This paper describes the clinical phenomenology and contemporary pathophysiology of concurrent oscillations of the eyes and the head that are present in neurological conditions with diverse etiologies. Recent findings One classic example is spasmus nutans in which the eye oscillations are the primary pathology while head nodding is thought to be an operant conditional response that suppresses the eye oscillations to facilitate clear vision. The second example is a combination of head tremor and inadequate compensatory eye movements due to vestibular hypofunction leading to the illusion of pendular nystagmus – hence the condition is called pseudonystagmus. Cerebellar degeneration in ataxia-telangiectasia or synchronized spontaneous discharge from the inferior olive and cerebellum in the syndrome of ocular palatal tremor with dystonia are examples of eye and head oscillations due to the impairment in cerebellar outflow. Infantile nystagmus syndrome also presents with eye and head oscillations, but here the relationship between the two types of oscillations differs among patients and is still unclear. Summary The clinical features and putative pathophysiology of diverse disorders of the eyes and head that produce unwanted oscillations are reviewed and some analogies between eye and head oscillations are suggested. Key clinical pearls that are essential to separate these disorders at the bedside are also emphasized. PMID:26641814

    2012-11-01

    To review the literature on early visual manifestations of subacute sclerosing panencephalitis (SSPE) with regard to two patients who had visual problems preceding the onset of neurological symptoms. One patient had cortical visual disturbances and the other had visual loss due to retinal pigment epithelial changes. SSPE is a chronic encephalitis characterized by a history of measles infection and a progressive disease of the central nervous system that still occurs frequently in countries with insufficient measles immunization. Visual manifestations can occur as a result of involvement of the pathways that lead from the retina to the occipital cortex during the course of the disease, but are rare as a presenting sign. Fundus changes, especially macular retinitis and macular pigment disturbances, appear to be the most common ocular manifestations of SSPE. Ophthalmologists must be aware that SSPE can knock their door with ocular findings of SSPE, months or years before the onset of neurological symptoms.

    Full Text Available Background: There is an increase in the incidence of traumatic optic neuropathy (TON due to increasing urbanization and rapid spurt in the number of motor vehicles on the road. Despite early presentation and ease of diagnosis the visual outcomes in TON are still limited. There is also significant confusion about the timing, dose and efficacy of steroid treatment in its management. Purpose: To provide a clinical update of the pros and cons of steroid therapy for TON. Design: The paper is a retrospective review of the currently available literature in the English language indexed in PubMed. Methods: A PubMed search was conducted by the authors using the following terms: Traumatic optic neuropathy, megadose, steroids, methylprednisolone. Relevant original articles, review articles, and case reports related to the topic of discussion were evaluated and discussed in the paper. Results: There is no prospective randomized control trial evaluating the effect of steroids in TON. There are varying reports on the effect of steroid therapy from significant improvement to no difference compared to observation. Conclusion: The decision to give steroids to patients with TON has to be on an individual case to case basis and must involve informed consent from the patient. There are documented advantages and disadvantages of steroid therapy and a prospective, randomized, controlled trial is necessary comparing steroids, surgery and observation before definitive management can be evolved.

    On the basis of strong research evidence, the pathogenesis of sinusitis involves 3 key factors: sinusostia obstruction, ciliary dysfunction, and thickening of sinus secretions. On the basis of studies of the microbiology of otitis media, H influenzae is playing an increasingly important role in the etiology of sinusitis, exceeding that of S pneumoniae in some areas, and b-lactamase production by H influenzae is increasing in respiratory isolates in the United States. On the basis of some research evidence and consensus,the presentation of acute bacterial sinusitis conforms to 1 of 3 predicable patterns; persistent, severe, and worsening symptoms. On the basis of some research evidence and consensus,the diagnosis of sinusitis should be made by applying strict clinical criteria. This approach will select children with upper respiratory infection symptoms who are most likely to benefit from an antibiotic. On the basis of some research evidence and consensus,imaging is not indicated routinely in the diagnosis of sinusitis. Computed tomography or magnetic resonance imaging provides useful information when complications of sinusitis are suspected. On the basis of some research evidence and consensus,amoxicillin-clavulanate should be considered asa first-line agent for the treatment of sinusitis.

    Acute invasive fungal sinusitis is the most aggressive form of fungal sinusitis and can be fatal, especially in patients who are immunosuppressed. Early diagnosis and intervention are crucial and potentially lifesaving, so primary care providers must maintain a high index of suspicion for this disease. Patients may need to be admitted to the hospital for IV antifungal therapy and surgical debridement.

    Myxoma is a slow growing, benign neoplasm, which pathogenesis still remains disputed. The lesion has well-defined borders but a true capsule is absent. Because of that myxoma can be locally invasive causing bone destruction. A change is mainly observed among persons between 20-30 years of age and is very uncommon in the pediatric population. Most myxomas are observed in myocardium, but rarely may also manifest in the head and neck region. In the paper we describe an unusual case of myxoma of maxillary sinus in a female infant. Diagnostic challenges, treatment, outcome, post-operative follow-up are discussed as well as a review of the literature in order to present many features of this rare pathology. © 2016 MEDPRESS.

    Full Text Available The purpose: to prove diagnostic capabilities of modern radiation techniques in odontogenic maxillary sinusitis. Material and methods: The study involved 546 patients with sinusitis. The following methods have been used: X-ray of the paranasal sinuses, contrast maxillary sinus radiography, contact intraoral radiographs, orthopantomography, computer tomography and magnetic resonance imaging. Results. In 7,9% of cases the presence of odontogenic sinusitis has been established, in 92,1 % rhinogenous sinusitis has been revealed. The work provides information about the effectiveness of various radiation techniques in the diagnosis of odontogenic sinusitis. Conclusion. For suspected odontogenic sinusitis, treatment of choice includes the combined use of X-ray of the paranasal sinuses in the mentoanterior projection and contact intraoral radiographs of «causal teeth». Computer tomography is the most informative additional method to clarify the diagnosis of odontogenic sinusitis.

    The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.

    2004-12-01

    Acute paranasal sinus infection in children is often diagnosed clinically without the need for radiographic confirmation. Most cases have a favorable outcome following appropriate antibiotic therapy. A small percentage of cases where symptoms and signs are persistent or severe will require emergent imaging to rule out complications related to local spread of disease intraorbitally or intracranially. A strong index of suspicion is required in such cases, and cross-sectional imaging evaluation with CT and MRI should include axial and coronal images of the paranasal sinuses and, where appropriate, the orbits and brain (with attention to the cavernous sinus). There is no role for plain radiography in the evaluation of the complications of acute sinusitis in the pediatric patient. (orig.)

  9. Presurgical evaluation for partial epilepsy: Relative contributions of chronic depth-electrode recordings versus FDG-PET and scalp-sphenoidal ictal EEG

    Engel, J. Jr.; Henry, T.R.; Risinger, M.W.; Mazziotta, J.C.; Sutherling, W.W.; Levesque, M.F.; Phelps, M.E.

    1990-11-01

    One hundred fifty-three patients with medically refractory partial epilepsy underwent chronic stereotactic depth-electrode EEG (SEEG) evaluations after being studied by positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) and scalp-sphenoidal EEG telemetry. We carried out retrospective standardized reviews of local cerebral metabolism and scalp-sphenoidal ictal onsets to determine when SEEG recordings revealed additional useful information. FDG-PET localization was misleading in only 3 patients with temporal lobe SEEG ictal onsets for whom extratemporal or contralateral hypometabolism could be attributed to obvious nonepileptic structural defects. Two patients with predominantly temporal hypometabolism may have had frontal epileptogenic regions, but ultimate localization remains uncertain. Scalp-sphenoidal ictal onsets were misleading in 5 patients. For 37 patients with congruent focal scalp-sphenoidal ictal onsets and temporal hypometabolic zones, SEEG recordings never demonstrated extratemporal or contralateral epileptogenic regions; however, 3 of these patients had nondiagnostic SEEG evaluations. The results of subsequent subdural grid recordings indicated that at least 1 of these patients may have been denied beneficial surgery as a result of an equivocal SEEG evaluation. Weighing risks and benefits, it is concluded that anterior temporal lobectomy is justified without chronic intracranial recording when specific criteria for focal scalp-sphenoidal ictal EEG onsets are met, localized hypometabolism predominantly involves the same temporal lobe, and no other conflicting information has been obtained from additional tests of focal functional deficit, structural imaging, or seizure semiology.

    Full Text Available Silent sinus syndrome (SSS is a rare entity that is associated with spontaneous, painless, unilateral enophthalmos and hypoglobus resulting from downward bowing of the orbital floor in the absence of any symptomatic sinonasal disease. The diagnosis is suspected clinically, but it is confirmed radiologically by its characteristic imaging features that include maxillary sinus outlet obstruction, sinus opacification and sinus volume loss caused by inward retraction of the sinus walls. The purpose of this article is to acquaint the reader with the clinical and imaging features of the SSS, along with a brief discussion about its pathogenesis and treatment, which is relatively unknown among oral and maxillofacial radiologists.

    Full Text Available Background. Mucocoele is histopathologically benign, cystic change of paranasal sinuses filled with mucoid contents, which with its growth is pressuring and destroying local bone walls. In only 3% of the cases it can be localized in maxillary sinuses. Etiology is unknown. Pyocoele develops by secondary infection. Case report. The male patient was 21 years old. His symptoms were runny nose with thick contents and heavy breathing on the right side of the nose, headaches, as well as the swelling of the right cheek. During clinical examination, the expansive change was found. It was completely closing the right side of the nose cavity. Computerized tomography (CT of paranasal cavities showed excessive expansion of the right maxillary sinus, with very thinned walls, while the cavity was filled with liquid. After antibiotics therapy, the radical operation of the right maxillary sinus was performed, based on Caldwell Luc method. The frontal wall was found to be extremely convex and thinned, while the medial wall was with dehiscention. The cystic change was extirpated. Mucocoele was proved by pathohistologic findings. Its wall was about 2 mm thick and it showed squamous metaplasia in the large part of the mucocoela epithel. In the submucosa fibrosis and inflammatory infiltrate was present. Postoperative follow-up was under control. Clinically and radiographycaly, six months after therapy, the patient does not have troubles. Conclusion. The rare localization of the mucocoeles in maxillary sinus can be explained with the width of the maxillary ostia. Infected mucocoeles, expanded to the local anatomical structures, should be operated on with classic radical surgical operation. .

  17. Allergic fungal sinusitis causing nasolacrimal duct obstruction.

    Kim, Charles; Kacker, Ashutosh; Chee, Ru-Ik; Lelli, Gary J

    2013-04-01

    Allergic fungal sinusitis is thought to represent a chronic autoimmune reaction directed against fungal elements within the sinuses, and is commonly seen in individuals with a history of chronic sinusitis that is refractory to medical therapy. The authors present a case of allergic fungal sinusitis involving the lacrimal drainage system. A 54-year-old woman initially presented with recurrent erythema and induration of the left nasolacrimal sac due to dacryocystitis, which was unresponsive to treatment with topical and systemic antibiotics. Radiological evaluation demonstrated the presence of multiple soft tissue masses along the medial canthi. During subsequent endoscopic dacryocystorhinostomy, significant amounts of allergic mucin were found within the sinuses and marked eosinophilia was present within tissue obtained from the lacrimal sac, findings highly suggestive of allergic fungal sinusitis. A diagnosis of allergic fungal sinusitis should be considered in patients presenting with epiphora in the appropriate clinical context. However, involvement of the lacrimal drainage system is an exceedingly unusual presentation.

    Background and Purpose Aneurysmal bone cysts (ABCs) rarely involve the cranium and have seldom been reported in pregnancy. Clinical Presentation We describe a case of a 28-year-old woman who presented at 37 weeks of gestation with 3 months of gradually worsening vision, 10 months of proptosis, and restricted ocular motility on the left. Brain imaging revealed a multicystic enhancing mass measuring 5.9 × 5.3 × 3.7 cm, centered on the cribriform plate on the left, extending into the anterior cranial fossa superiorly as well as the left nasal cavity, maxillary, sphenoid, and frontal sinuses. Her clinical course is described in detail; 3-month postoperative imaging demonstrated no residual mass. Conclusion A literature review revealed five previous cases of ABCs associated with pregnancy. We report a rare case of a giant ABC of fibrous dysplasia involving the paranasal sinuses and anterior cranial fossa. We postulate on the possible influence of pregnancy on the clinical course.

    The objective of this study was to comparatively evaluate 3 different sinus lift tools, namely umbrella-shaped sinus lift curette YSL-04, our recently designed probe-improved sinus lift curettes, and our newly invented elevator 014, using our previous developed goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time. Goat ex vivo models for direct visualizing the effectiveness of detaching sinus mucosa in real time were generated according to our previously developed protocol. The effectiveness for each tool was evaluated through the length of sinus mucosa detached in mesial and distal directions or buccal and palatal directions, and the space volume created by detaching maxillary sinus mucosa in mesial, distal, buccal and palatal directions. The results showed that all 3 sinus lift tools could transcrestally detach the maxillary sinus mucosa and create extra space under the elevated sinus floor on the goat ex vivo sinus models. Moreover, our newly invented elevator 014 had advantages over the other 2 in term of the capability to detach the sinus mucosa. Our newly invented elevator 014 might be a promising tool for detaching maxillary sinus mucosa in transcrestal maxillary sinus floor elevation.

  20. Anatomical aspects of sinus floor elevations.

    van den Bergh, J P; ten Bruggenkate, C M; Disch, F J; Tuinzing, D B

    2000-06-01

    Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizontal position. The new elevated sinus floor, together with the inner maxillary mucosa, will create a space that can be filled with graft material. Sinus lift procedures depend greatly on fragile structures and anatomical variations. The variety of anatomical modalities in shape of the inner aspect of the maxillary sinus defines the surgical approach. Conditions such as sinus floor convolutions, sinus septum, transient mucosa swelling and narrow sinus may form a (usually relative) contra-indication for sinus floor elevation. Absolute contra-indications are maxillary sinus diseases (tumors) and destructive former sinus surgery (like the Caldwell-Luc operation). The lateral sinus wall is usually a thin bone plate, which is easily penetrated with rotating or sharp instruments. The fragile Schneiderian membrane plays an important role for the containment of the bonegraft. The surgical procedure of preparing the trap door and luxating it, together with the preparation of the sinus mucosa, may cause a mucosa tear. Usually, when these perforations are not too large, they will fold together when turning the trap door inward and upward, or they can be glued with a fibrin sealant, or they can be covered with a resorbable membrane. If the perforation is too large, a cortico-spongious block graft can be considered. However, in most cases the sinus floor elevation will be deleted. Perforations may also occur due to irregularities in the sinus floor or even due to immediate contact of sinus mucosa with oral mucosa. Obstruction of the antro-nasal foramen is, due to its high location, not a

    2013-12-02

    Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school. We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis in adults and children. We searched CENTRAL 2013, Issue 4, MEDLINE (January 1966 to May week 2, 2013), EMBASE (1990 to May 2013) and bibliographies of included studies. Randomised controlled trials (RCTs) comparing INCS treatment to placebo or no intervention in adults and children with acute sinusitis. Acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work. Two review authors independently extracted data, assessed trial quality and resolved discrepancies by consensus. No new trials were found for inclusion in this update. Four studies involving 1943 participants with acute sinusitis met our inclusion criteria. The trials were well-designed and double-blind and studied INCS versus placebo or no intervention for 15 or 21 days. The rates of loss to follow-up were 7%, 11%, 41% and 10%. When we combined the results from the three trials included in the meta-analysis, participants receiving INCS were more likely to experience resolution or improvement in symptoms than those receiving placebo (73% versus 66.4%; risk ratio (RR) 1.11; 95% confidence interval (CI) 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement of symptoms or complete relief: for mometasone furoate 400 µg versus 200 µg (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and

    2012-06-01

    Purpose: To investigate the clinical features, prognostic factors, and toxicity of treatment for unresectable carcinomas of the nasal cavity and paranasal sinus (NCPS) treated with proton beam therapy (PBT). Methods and Materials: Seventeen patients (13 men, 4 women) with unresectable carcinomas of the NCPS who underwent PBT at University of Tsukuba between 2001 and 2007 were analyzed. The patients' median age was 62 years (range, 30-83 years). The tumors were located in the nasal cavity in 3 patients, the frontal sinus in 1, the ethmoid sinus in 9, and the maxillary sinus in 4. The clinical stage was Stage IVA in 5 cases, IVB in 10, and recurrent in 2. The tumors were deemed unresectable for medical reasons in 16 patients and because of refusal at a previous hospital 4 months earlier in 1 patient. All the patients received PBT irradiation dose of 22-82.5 GyE and a total of 72.4-89.6 GyE over 30-64 fractions (median 78 GyE over 36 fractions) with X-ray, with attention not exceeding the delivery of 50 GyE to the optic chiasm and brainstem. Results: The overall survival rate was 47.1% at 2 years and 15.7% at 5 years, and the local control rate was 35.0% at 2 years and 17.5% at 5 years. Invasion of the frontal or sphenoid sinus was a prognostic factor for overall survival or local control. Late toxicity of more than Grade 3 was found in 2 patients (brain necrosis in 1 and ipsilateral blindness in 1); however, no mortal adverse effects were observed. Conclusion: Proton beam therapy enabled a reduced irradiation dose to the optic chiasm and brainstem, enabling the safe treatment of unresectable carcinomas in the NCPS. Superior or posterior extension of the tumor influenced patient outcome.

    To use cross-sectional imaging (helical computed tomography (CT)) combined with conventional anatomical dissection to define the normal anatomy of the nasal cavity and bony cavitations of the koala skull. Helical CT scans of the heads of nine adult animals were obtained using a multislice scanner acquiring thin slices reconstructed in the transverse, sagittal and dorsal planes. Subsequent anatomical dissection permitted confirmation of correct identification and further delineation of bony and air-filled structures visible in axial and multiplanar reformatted CT images. The nasal cavity was relatively simple, with little scrolling of nasal conchae, but bony cavitations were complex and extensive. A rostral maxillary recess and ventral conchal, caudal maxillary, frontal and sphenoidal paranasal sinuses were identified and characterised. Extensive temporal bone cavitation was shown to be related to a large epitympanic recess. The detailed anatomical data provided are applicable to future functional and comparative anatomical studies, as well as providing a preliminary atlas for clinical investigation of conditions such as cryptococcal rhinosinusitis, a condition more common in the koala than in many other species. © 2013 Australian Veterinary Association.

Scans were performed before and after each delivery with a portable CT machine (Xoran xCAT), and blinded assessments were made for distribution to individual sinuses. Total sinus distribution was greater post-ESS (P squeeze bottle > pressurized spray (P spray solutions in un-operated sinuses provide little more than nasal cavity distribution. Use of squeeze bottle/neti pot post-ESS offers a greatly enhanced ability to deliver solutions to the paranasal sinuses.

    A 55-year-old male patient was referred to our clinic with signs and symptoms of recurring sinusitis after a right maxillary sinus floor augmentation for implantological purposes. Investigations showed an antibiotic-resistant ethmoidomaxillary sinusitis resulting from bone graft infection and displacement of previously inserted xenograft material into the maxillary sinus. The patient thus underwent a surgical procedure combining nasal endoscopy and oral surgery in order to remove the infected graft and restore sinusal drainage. The procedure was apparently successful but sinusitis relapsed after surgery and persisted despite 2 weeks of antibiotic therapy and local medications. A CT scan showed persistence of grafting fragments in the maxillary sinus. A new surgical procedure was scheduled while a more accurate endoscopic local medication was performed. Six hours after the treatment, the patient spontaneously expelled the fragments and promptly recovered. The patient successfully underwent another maxillary sinus floor augmentation procedure 6 months later. PMID:23234824

    Infections due to the Mycobacterium tuberculosis of the head and neck region mainly affect the cervical lymph nodes. We report a rare case of paranasal sinus tuberculosis. The patient presented as an emergency with right-sided headache and epiphora. Clinical, radiological and laboratory results yielded a diagnosis of acute exacerbated chronic sinusitis with meningeal affection resulting from transmigration. Histological and molecular investigations confirmed mycobacterial infection of the paranasal sinuses.

    Are oral or parenteral corticosteroids associated with improved clinical outcomes in patients with acute sinusitis compared with placebo or nonsteroidal anti-inflammatory drugs (NSAIDs)? Oral corticosteroids combined with antibiotics may be associated with modest benefit for short-term relief of symptoms in adults with severe symptoms of acute sinusitis compared with antibiotics alone. Oral corticosteroids as monotherapy are not associated with improved clinical outcomes in adults with clinically diagnosed acute sinusitis.

    For well over 100 years, it has been appreciated that maxillary dental infections can cause sinusitis. This insight has been largely overlooked with the advent of functional endoscopic sinus surgery (ESS) and its emphasis on the osteomeatal complex. We review several recent case series and reviews of odontogenic sinusitis that characterize and discuss emerging diagnostic modalities in odontogenic sinusitis. In recent publications on odontogenic sinusitis, up to 40% of chronic bacterial maxillary sinus infections are attributed to a dental source, which is far higher than the previously reported incidence of 10%. Plain dental films and dental evaluations frequently fail to detect maxillary dental infection that can be causing odontogenic sinusitis. However, sinus computed tomography (CT) or Cone Beam Volumetric CT (CBVCT) are far more successful in identifying dental disease causing sinusitis. The microbial pathogens of odontogenic sinusitis remain unchanged from earlier reviews; however, the clinical findings in odontogenic sinusitis are better described in recent reviews. Successful treatment of odontogenic sinusitis requires management of the odontogenic source and may require concomitant or subsequent sinus surgery. Odontogenic sinusitis is frequently recalcitrant to medical therapy and usually requires treatment of the dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent ESS is required. Evaluation of all patients with persistent chronic rhinosinusitis (CRS) should include inspection of the maxillary teeth on CT scan for evidence of periapical lucencies. Unilateral recalcitrant disease associated with foul smelling drainage is especially characteristic of odontogenic sinusitis. High-resolution CT scans and CBVCT can assist in identifying dental disease.

    Acute sinusitis is the inflammation and swelling of the nasal and paranasal mucous membranes and is a common reason for patients to seek primary care consultations. The related impairment of daily functioning and quality of life is attributable to symptoms such as facial pain and nasal congestion. To assess the effects of systemic corticosteroids on clinical response rates and to determine adverse effects and relapse rates of systemic corticosteroids compared to placebo or standard clinical care in children and adults with acute sinusitis. We searched CENTRAL (2014, Issue 1), MEDLINE (1966 to February week 1, 2014) and EMBASE (January 2009 to February 2014). Randomised controlled trials (RCTs) comparing systemic corticosteroids to placebo or standard clinical care for patients with acute sinusitis. Two review authors independently assessed the methodological quality of the trials and extracted data. Five RCTs with a total of 1193 adult participants met our inclusion criteria. We judged methodological quality to be moderate in four trials and high in one trial. Acute sinusitis was defined clinically in all trials. However, the three trials performed in ear, nose and throat (ENT) outpatient clinics also used radiological assessment as part of their inclusion criteria. All participants were assigned to either oral corticosteroids (prednisone 24 mg to 80 mg daily or betamethasone 1 mg daily) or the control treatment (placebo in four trials and non-steroidal anti-inflammatory drugs (NSAIDs) in one trial). In four trials antibiotics were prescribed in addition to oral corticosteroids or control treatment, while one trial investigated the effects of oral corticosteroids as a monotherapy.When combining data from the five trials, participants treated with oral corticosteroids were more likely to have short-term resolution or improvement of symptoms than those receiving the control treatment: at days three to seven (risk ratio (RR) 1.3, 95% confidence interval (CI) 1.1 to 1

    The aim of this study was to assess the presence of an occipital sinus in both children and adults, and to detail its main associated anatomical characteristics. One hundred of patients' MRI (3D T1 EG) between 0 and 86 years old were studied, in sagittal and axial sections, with the software DxMM. Occipital sinus length, perimeter, and cerebellar falx length measurements were performed with the software's tools. Forty-three percent of patients had an occipital sinus (average perimeter was 3.02 mm, average length was 19.85 mm), and 23.26% of these patients had a cerebellar falx, 30.23% of these patients had one vein or more draining into the occipital sinus. Sixty-two percent of children had an occipital sinus (average perimeter was 2.87 mm, average length was 21.63 mm), and 29.03% of them had a cerebellar falx. Twenty-four percent of adults had an occipital sinus (average perimeter was 3.4mm, average length was 15.28 mm), and 8.33% of them had a cerebellar falx. This work highlights a link between the age and the occipital sinus existence. The perimeter of this sinus seems to be superior for adults, but its length seems to be superior for children. A cerebellar falx with the occipital sinus was found more frequently for children. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Allergic fungal sinusitis (AFS) is a subtype of eosinophilic chronic rhinosinusitis (CRS) characterized by type I hypersensitivity, nasal polyposis, characteristic computed tomography scan findings, eosinophilic mucus, and the presence of fungus on surgical specimens without evidence of tissue invasion. This refractory subtype of CRS is of the great interest in the pediatric population, given the relatively early age of onset and the difficulty in managing AFS through commercially available medical regimens. Almost universally, a diagnosis of AFS requires operative intervention. Postoperative adjuvant medical therapy is a mainstay in the treatment paradigm of pediatric AFS. Copyright © 2012 Elsevier Inc.

    An aberrant sinus anatomy or pathology can influence the sinus lift technique if it is encountered during surgical exposure. The purpose of the present study was to determine the prevalence of sinus disease and variations of normal anatomy among edentulous patients prior to sinus augmentation. 120 patients attending a private surgical practice (53 women and 67 men, with a mean age of 62.02 years, ranging between 34 and 81 years old) for whom treatment was planned for sinus augmentation were evaluated--medical history, radiographic and clinical examinations. Computerized tomograms (CT) and 3D reconstructions from 240 sinuses were analyzed using Dental CT. Abnormalities were diagnosed in 74.2% of cases. Mucosal thickening was the most prevalent abnormality (68.3%), followed by retention cysts (15.8%) and opacification (9.2%). The diagnosed conditions included mucosal thickening, chronic sinusitis, sinus cysts and polyps. The prevalence of one or more septa per sinus was found to be 30%. Males present pathology more often than females (p=.028). No statistical correlation could be found between age and pathology (p>0.05) No significant differences in age or gender between patients with and without sinus septum were found (p>0.05). The results reinforce the importance of thorough history taking and clinical and radiographic assessment prior to performing sinus augmentation, to prevent the probability of complications.

    This study aimed to evaluate the clinical significance of maxillary sinus hypoplasia and isolated agenesis of the uncinate process in sinusitis aetiology. Three patients with isolated agenesis of the uncinate process and 27 patients with 43 maxillary sinus hypoplasia variations were recruited. The frequencies of sinusitis episodes and radiological findings were compared between patient subgroups. In all, 23 type I maxillary sinus hypoplasia, 13 type II maxillary sinus hypoplasia and 7 type III maxillary sinus hypoplasia variations were detected. Patients with isolated agenesis of the uncinate process underwent antibiotic treatment an average of 7 times per year, whereas those with types I, II and III maxillary sinus hypoplasia were treated 1.57, 3.22, and 5.75 times per year, respectively, over a 5-year period. The antibiotic treatment frequency for patients with isolated agenesis of the uncinate process was significantly higher than for those with types I and II maxillary sinus hypoplasia. Isolated agenesis of the uncinate process seems to play a stronger role than types I and II maxillary sinus hypoplasia in the pathophysiology of chronic sinusitis.

    To determine the prevalence,location, and distribution of sinus tracts in patients referred for endodontic consultation. This cohort study included 1,119 subjects referred for endodontic consultation, 108 of whom presented with sinus tracts. Following clinical and radiographic examination, the diameter of the rarifying osteitis lesion on the radiograph was measured and the path and origin of the sinus tracts determined. Signs and symptoms, tooth site,buccal/lingual location, and diameter were recorded. Data were statistically analyzed using Pearson chi-square test. Sinus tracts originated mainly from maxillary teeth (63.1%); only 38.9% originated from mandibular teeth. Chronic periapical abscess was the most prevalent diagnosed origin (71.0%). Broken restorations were highly associated with the presence of sinus tracts (53.0%). The most frequent site of orifices was buccal(82.4%), followed by lingual or palatal (12.0%). Orifices on the lingual aspect of the gingiva were observed in mandibularmolars. There was an 86.8% correlation between the occurrence of an apically located sinus tract and apical rarifying osteitis(P<.01). Sinus tract in the lingual or palatal aspect of the gingiva is relatively common. Practitioners should look for signs of sinus tract during routine examination

    Extreme bone resorption in posterior maxilla may lead to absence of part of the sinus floor. This phenomenon has been termed sinus floor bone failure, and may compromise sinus floor augmentation. The present article aims to evaluate risk factors related to sinus floor bone failures and to evaluate the influence of these failures in sinus floor augmentation outcomes in patients with severely atrophic posterior maxilla. In this case-control study, patients were selected among those referred for sinus floor augmentation. Only patients presenting a ridge bone height of less than 3 mm were included. Cases were defined as presenting sinus floor bone failure, whereas controls did not present any interruption in the sinus floor bone. Information collected included clinical dental records and computed tomographic assessment of sinus width, septa, and schneiderian membrane. Risk estimates for sinus floor bone failures were calculated as adjusted odds ratios (AORs) with 95% confidence intervals (CIs) using conditional logistic regression analyses. A p value under 0.05 was considered statistically significant. In addition, sinus floor augmentation outcomes of both groups were also assessed. In all, 23 cases and 58 controls were included in the study. Sinus floor bone failures were significantly associated with the number of missing posterior teeth (AOR 3.67; 95% CI 0.86 to 15.63; p = .046) and a history of periodontitis (AOR 6.39; 95% CI 1.86 to 21.95; p = .002). Of the total, 15 cases and 27 controls underwent sinus floor augmentation. Schneiderian membrane perforation occurred during the surgery of two cases and of one control. No implants were lost during a mean postsurgical follow-up of 20 months. The number of missing posterior teeth and a history of periodontitis may be considered as risk factors for sinus floor bone failures. © 2013 Wiley Periodicals, Inc.

    Objectives: Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior ethmoidal sinusitis. Study Design: This is a retrospective cohort study performed on 55 patients diagnosed of odontogenic sinusitis and treated surgically by functional endoscopic sinus surgery. Results: This study showed that 52.7% of odontogenic maxillary sinusitis spreads to anterior ethmoid, causing added anterior ethmoid sinusitis. We found that 92.3% of the odontogenic maxillary sinusitis (who underwent middle meatal antrostomy) and 96.5% of the odontogenic maxillary sinusitis extended to the anterior ethmoid (treated with middle meatal antrostomy and anterior ethmoidectomy) were cured. Conclusions: Ethmoid involvement is frequent in maxillary odontogenic sinusitis. The ethmoid involvement does not worsen the results of “functional endoscopic sinus surgery” applied to the odontogenic sinusitis. Key words:Odontogenic maxillary sinusitis, ethmoiditis, functional endoscopic sinus surgery. PMID:24608208

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. © 2016 The authors.

    Purpose The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. Materials and Methods A retrospective chart analysis was completed on twenty-seven patients with odontogenic sinusitis. They were all treated at Kangbuk Samsung Hospital between February 2006 and August 2008. The study protocol and informed consent forms were approved by the institutional review boards for human beings at Kangbuk Samsung Hospital. Results Ten patients (37.0%) had dental implant related complications and 8 (29.6%) had dental extraction related complications. Unilateral purulent nasal discharge was the most common symptom (66.7%). The therapeutic modality included transnasal endoscopic sinus surgery in 19 (70.4%) patients, and a Caldwell-Luc operation in two (7.4%) patients. Conclusion In our study, there was no significant difference in the incidence between genders. The average age of the patients was 42.9 years. The incidence was highest in the fourth decade. There were no significant differences between the symptoms of odontogenic sinusitis and that of other types of sinusitis. However, almost all of the patients with odontogenic sinusitis had unilateral symptoms. Iatrogenic causes, which include dental implants and dental extractions, were the most common etiologic factors related to the development of odontogenic sinusitis. Therefore, a preoperative consultation between a rhinologist and a dentist prior to the dental procedure should be able to reduce the incidence of odontogenic sinusitis. PMID:20879062

    2007-01-01

    Thrombophlebitis of dura venous sinuses is a rare intracranial complication of otitis media, which may be sometimes accompanied by symptoms or sepsis. Anatomical conditions and early diagnosis of this vascular complication determine the treatment modality. Aim of this study was the assessment of diagnostics and treatment of venous sinuses thrombophlebitis in acute and chronic otitis media considering anatomy and the venous sinuses and status of coagulation system. Otogenic thrombophlebitis may occur in lateral, transverse, upper and lower petrosal sinuses, and rarely in cavernous. In some cases thrombophlebitis proces may expand into brain or emissary mastoid veins. Lateral sinus thrombophlebitis in chronic otitis media usually appears clinically as septic fever, earache, and increasing neurologic signs. In acute otitis media when thrombophlebitis develops the patient complains about headache, high fever and visual acquity. Diagnosis of venous sinus thrombophlebitis is based on clinical signs, radiological imaging (CT scan, MRI), bacteriological examinations and laboratory biochemical tests. Contrast enhanced CT scan shows "delta sign". Septic thrombophlebitis sinus sigmoidei is caused by mixed bacterial flora. Surgical treatment in cases with septic thrombus consists of radical modiffied ear operation and lateral sinus exposure. Thrombectomy and jugular vein ligation is performed when sepsis or thrombus is present. Mastoidectomy and tympanic cavity drainage is performed in cases with lateral sinus thrombosis in acute mastoiditis. Intravenous antibiotics therapy should be continued for 2 weeks. Anticoagulants should be given taking into consideration parameters of coagulation system and the type of thrombus. Treatment results of venous sinuses thrombophlebitis are good if they are not accompanied by other intracranial complications.

    The frequency of maxillary sinusitis of dental origin (MSDO) is under estimated. The medical and surgical treatment has improved thanks to endoscopic guidance. We report our experience and strategy in the treatment of MSDO. Twenty-two patients presenting with MSDO were treated between 1998 and 2008. The results were evaluated on clinical, functional, sinusal, and odontologic signs. MSDO accounted for 16% of surgically managed sinusitis. CT was performed in 95% of cases. The etiologies were apical leakage in seven patients, migration of a tooth or root during extraction, or presence of ectopic tooth in the sinus in nine patients, a cyst in three patients, and oroantral communication in three patients. Surgery was performed after antibiotic and NSAID treatment. The first surgical step was the treatment of the odontogenic source. The second step was sinus drainage by endoscopic treatment in 64%, Caldwell-Luc in 23%, and drainage by oroantral communication enlarged then closed in the same operative time in 13%. The follow up ranged from 3 months to 10 years. Early postoperative superinfection was observed in two patients. Two patients presented with recurrent sinusitis. The postoperative sequels were hyposmia in three patients, dental pulpotomy, and trigeminal neuralgia in five patients treated by Caldwell-Luc surgery. Nasal endoscopy has improved the surgical management of MSDO. It makes curettage and exclusion of sinus cavities obsolete. It is reliable and has a low rate of complications. The best treatment remains prevention. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Full Text Available ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01. RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006 between the tooth roots in diseased maxillary sinuses (6.09% and those in normal sinuses (3.43%. The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001. Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.

  20. [Conservative therapy of chronic sinusitis].

    2012-01-01

    The chronic rhinosinusitis is defined as chronic inflammation of the nose and nasal sinuses, with or without nasal polyps. Patients suffering from chronic rhinosinusitis report about nasal obstruction and secretion, olfactory impairment, head and facial pain. These symptoms cause also considerable impact on quality of life. Therefore, an adequate rhinological diagnostics as well as therapies are essential. This paper reviews the pharmacologic and non-pharmacologic therapy of chronic rhinosinusitis. First choice of therapy should be topical glucocorticoids. The application of glucocorticoids causes anti-inflammatory and certain curative effects. Hypertonic salt solutions improve nasal symptoms. Long-term therapy with oral macrolides might improve median to severe symptoms of chronic rhinosinusitis without nasal polyps. An additional therapy with antihistamines is possible in patients with an allergy. Adaptive desensitization in patients suffering from analgesic-intolerance associating among other with nasal polyps is currently the single causal therapy. Therefore, frequency of endonasal revision surgery is reduced after desensitization.

  1. A Rational Approach to Sinus Augmentation: The Low Window Sinus Lift

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique that also exploits the guided surgery approach for design and preparation of a lateral window for sinus augmentation, the Low Window Sinus Lift. To illustrate the use of this approach, a case is presented in which the 50-year-old patient had the left maxillary first molar extracted, followed two months later by sinus augmentation and placement of three implants. One year after delivery of the definitive prosthesis, all three implants were successful, and the prosthesis was fully functional. Controlled studies should be undertaken to assess whether this technique provides significant advantages compared to other sinus augmentation approaches.

    Objective: Our aim was to determine whether inward or outward movement of the secretions in the paranasal sinuses due to nose blowing after nasal decongestion has any effect on the paranasal sinus computed tomography (CT) images in patients with sinusitis and to asses whether nose blowing may result in misdiagnosis or overdiagnosis in radiological evaluation of sinusitis. Materials and methods: Twenty-four patients with chronic sinusitis were evaluated in an academic tertiary care hospital and data were collected prospectively. After coronal sinus computed tomography scans were performed at 100 mA setting which was half the value of the standard radiation dose suggested by the manufacturer, topical decongestion was applied to each nostril followed by nose blowing 10 min later. Sinus CT scans were then repeated at the same setting. We evaluated the mucosal thickness of medial, lateral, superior and inferior maxillary and frontal sinus walls and the maximal thickness in anterior ethmoidal cells. The measurements prior to and following nose blowing were compared with Wilcoxon signed ranks test. The obtained images were also staged using Lund-McKay staging system separately and the scores were compared with Student's t-test. Results: We observed a tendency towards reduction in mucosal thickness after nose blowing. There were statistically significant differences between maxillary sinus inferior wall and frontal sinus inferior wall mucosal thickness values prior to and after nose blowing. The difference however was very small, about 0.5 mm in magnitude and Lund-McKay score did not change in any of the patients after nose blowing. Conclusion: Nose blowing and topical nasal decongestion does not have any effect on the diagnostic accuracy of sinus CT in chronic sinusitis patients.

    The procedure of crestal maxillary sinus floor elevation presents a great challenge to the field of implant dentistry. Due to the limited visualization in this procedure, the effectiveness of detaching sinus mucosa could not be assessed in real time. We recently developed an ex vivo goat sinus model by cutting the goat residual skulls along four lines determined from computerized tomography (CT) scans, extracting the maxillary premolar or molar teeth, and preparing implant socket in the maxilla. The generated ex vivo goat sinus models exposed the maxilla and the whole maxillary sinus mucosa, thus enabling real-time observation of detaching maxillary sinus mucosa via directly visualizing the working situation of sinus lift tool in the models and directly measuring the length of detached mucosa and space volume generated under the elevated sinus mucosa. One commercially available umbrella-shaped sinus lift curette was used to detach the maxillary sinus mucosa to evaluate the effectiveness of the ex vivo goat sinus models. The results showed that this curette could detach the sinus mucosa 3.75 mm in length in the mesiodistal direction and 2.81 mm in the buccal-palatal direction. Moreover, a space volume of 52.7 μl could be created under the elevated sinus mucosa in the goat ex vivo models. All the experimental results suggested that this ex vivo goat sinus model might be useful in the evaluation of improved or newly designed sinus lift tools for elevating the maxillary sinus mucosa via the crestal approach.

    This study was performed to compare paranasal sinus tomosynthesis with computed tomography (CT) imaging as a radiologic tool to evaluate the paranasal sinuses, using measurement of the soft tissue thickness of the maxillary sinus. A total of 114 patients with sinusitis who underwent both paranasal sinus digital tomosynthesis (DT) and CT were enrolled in this retrospective study. Two observers independently assessed soft tissue thickness in both maxillary sinus chambers using both DT and CT images. The mean difference in soft tissue thickness measured by each observer was −0.31 mm on CT and 0.15 mm on DT. The mean differences in soft tissue thickness measured with DT and CT were −0.15 by observer 1 and −0.31 by observer 2. Evaluation of the agreement in measurement of soft tissue thickness in the maxillary sinus using DT and CT showed a high intraclass correlation, with the 95% limit of agreement ranging from −3.36 mm to 3.06 mm [intraclass correlation coefficient (ICC), 0.994: p<0.01] for observer 1 and from −5.56 mm to 4.95 mm (ICC, 0.984: p<0.01) for observer 2. As an imaging tool, DT is comparable to CT for assessing the soft tissue thickness of maxillary sinuses in patients with sinusitis.

    Allergic fungal sinusitis (AFS) is a form of fungal disease that has recently been considered a distinct clinicopathologic entity. Other forms of fungal sinusitis include acute-fulminant (invasive), chronic indolent (invasive) and mycetoma (non-invasive). Objectives were to assess the presentation and to describe the diagnostic techniques for allergic fungal sinusitis in our setup. Descriptive study was conducted in the Department of ENT and Head & Neck Surgery, Khyber Medical College and Khyber Teaching Hospital, Peshawar from January 2002 to April 2008. Twenty-three cases of allergic fungal sinusitis (ASF) were selected for the study. Data like, name, age, sex, address, clinical features, labs (Eosinophil count) and imaging studies (CT and/or MRI) were recorded, including the pre- and postoperative treatment, operative findings and postoperative results, recurrence of disease were also recorded. Surgical procedures were performed on all cases followed by medical treatment. Study revealed that AFS is a disease of younger age, mainly occurring in 2nd & 3rd decade of life, with male to female ratio 1:1.3. Allergic rhinitis (91%) and nasal polyposis (91%) were important associated factors. Nasal obstruction (96%), nasal discharge (91%), post-nasal discharge (87%) and unilateral multi sinus extension were important clinical features. Increased eosinophil count and increased IgE level was found in 78% cases. Histopathological analysis showed fungal hyphae in all cases and aspergillus was predominant organism on culture. Orbital erosion was seen in 78% and skull base erosion was observed in 9%. Recurrence of disease was seen in nine cases. Allergic fungal sinusitis (AFS) is a disease of young immunocompetent adults. Nasal obstruction, nasal discharge, nasal allergy and proptosis were the most common presentations. Initial diagnosis of allergic fungal sinusitis requires high index of suspicion in patients presenting with chronic rhinosinusitis, such cases should be

    To evaluate the clinical application of a full model-based iterative reconstruction (MBIR) algorithm in the ultra-low-dose paranasal sinus CT imaging of children. In the first phase, 16 low-dose CT dacryocystography (DCG) (80 kV/64 mAs) scans were reconstructed with MBIR and filtered back-projection (FBP) to demonstrate noise reduction capability of MBIR. MBIR images were also compared with the images of 21 standard-dose paranasal sinus patients reconstructed with adaptive statistical iterative reconstruction (ASIR) algorithm. In the second phase, 14 pediatric tumors patients (images with ASIR in the initial scan) who came for follow-up paranasal sinus CT scan were prospectively enrolled with reduced radiation and MBIR algorithm. In both study phases, image noise and the contrast noise ratio (CNR) of sphenoid was measured; and subjective image quality was evaluated. CTDIvol and DLP were recorded, and effective dose calculated. The CTDIvol value for the DCG group was 63.9% lower than the standard-dose sinus group (1.09 ± 0.01 mGy vs. 3.02 ± 0.35 mGy). Compared with the ASIR reconstruction in the standard-dose sinus patient group, images with MBIR in the ultra-low-dose DCG group had 39.9% lower noise (9.5 ± 0.8HU vs. 15.8 ± 3.3HU) and 63.6% higher CNR (14.4 ± 4.7 vs. 8.8 ± 2.2), with similar subjective image quality score. For the tumor patients, 65.5% dose reduction was achieved. Subjective quality scores were similar between the initial and follow-up scans. Objective noise was significantly lower for the follow-up group. MBIR provided equal or better image quality with significantly reduced radiation dose in paranasal sinus CT imaging of pediatric patients compared with standard-dose CT with ASIR algorithm.

    Tissue-engineered bone grafts represent an appealing alternative for maxillary sinus augmentation because they eliminate the significant drawbacks associated with extra- and intraoral bone-harvesting procedures. In the present case series, we document the outcomes of sinus augmentation surgery using tissue-engineered bone grafts. Three patients requiring bilateral sinus augmentation received tissue-engineered bone grafts combined with xenograft prior to implant placement. Implants were placed and loaded 6 and 12 months postaugmentation, respectively. Radiographs were taken and clinical examinations were performed preoperatively and at 4, 6, 12, and 18 months postaugmentation. Biopsies were obtained at 4 and 6 months postaugmentation. Standardized orthopantomograms were used to measure the posterior maxilla bone height. None of the patients experienced untoward complications during or following the therapeutic procedures. Ten implants were inserted into the augmented sinuses and loaded. Biopsies revealed a lack of inflammation or pathology; newly formed fibrous bone with osteoblastic activity and xenograft particles was evident. Compared to 4 months postaugmentation, augmented tissue was more mature at 6 months. The postoperative (18 months) bone height in augmented areas was significantly greater than the preoperative height (P bone height. Sinus augmentation using tissue-engineered bone grafts was successful in all three cases, permitting the subsequent insertion and loading of dental implants. The present cases demonstrated the feasibility of using engineered bone for sinus augmentation. Controlled clinical trials will be required to evaluate this new and evolving treatment modality.

    2017-06-01

    Silent sinus syndrome is an unusual cause of progressive enophthalmos and hypoglobus due to atelectasia of the maxillary sinus associated with osteolysis of the orbital floor. This syndrome is classically idiopathic, but the term is also used to describe traumatic or iatrogenic (surgical orbital decompression) cases. We report the case of a 33-year-old man who presented with a left orbital trauma without functional disorder. Computed tomography (CT) scan revealed a nondisplaced fracture of the left orbital floor. No surgical indication was made. Three months later, the patient presented with progressive enophthalmos. CT revealed a complete lysis of the left orbital floor and a left maxillary sinus atelectasia. The original nondisplaced fracture of the orbital floor was not responsible for enophthalmos but the associated fracture of the left uncinate process that induced the closure of the left maxillary sinus infundibulum. This induced in turn hypoventilation of the sinus and a left orbital floor lysis. Treatment consisted in surgical opening of the maxillary sinus ostium and reconstruction of the orbital floor.

    The purpose of this study was to determine the prevalence of sinus opacification among dental paediatric patients. Two hundred and eight Cone Beam Computed Tomography (CBCT) scans of dental patients under the age of 18 were reviewed for sinus opacification. Patients with any sinus-related signs or symptoms were excluded. The overall prevalence of sinus opacification was 48.1%. The ethmoid (28.4%) and maxillary (27.8%) sinuses were most frequently affected. There were no statistically significant differences for both age and gender. The high prevalence of sinus opacification in asymptomatic children emphasizes the necessity of clinical correlation.

    Accumulating evidence supports a role for inflammation in psychiatric illness, and the onset or exacerbation of psychiatric symptoms may follow non-CNS infections. Here, we provide the first detailed description of obsessive-compulsive and related psychiatric symptoms arising concurrently with sinusitis. We reviewed the charts of 150 consecutive patients evaluated in our Pediatric Acute-onset Neuropsychiatric Syndromes clinic for documented sinusitis as defined by the American Academy of Pediatrics guidelines. Sinusitis treatments, sinonasal imaging, and neuropsychiatric symptoms before, during, and after sinusitis onset were noted. Patients were included in the final review if they had a clear diagnosis of isolated sinusitis (without concurrent illness and/or immunodeficiency), and were evaluated during an episode of sinusitis. 10/150 (6.6%) patients had isolated sinusitis at the time of their neuropsychiatric deterioration. Eight patients received antibiotics to treat sinusitis, three of whom also received sinus surgery. Neuropsychiatric symptoms improved in all eight patients concurrent with resolution of sinusitis per parent report and clinician assessment. One patient did not follow through with recommended sinus surgery or antibiotics and her psychiatric symptoms persisted. One patient was lost to follow-up. Improvement of psychiatric symptoms correlated with resolution of sinus disease in this retrospective study. Identification, treatment, and resolution of underlying infections, including sinusitis, may have the potential to change the trajectory of some neuropsychiatric illnesses. Randomized clinical trials are needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Mammals present different types of spleen. In the past, attempts have been made to define characteristics for a classification of this organ, but the evolutionary process that has led to the splenic types of modern mammals has been poorly investigated. This review categorizes all mammalian spleens studied so far, synthesizing several earlier classification principles and updating them in the light of recent research. The main qualitative features are the type of circulation (closed, open or both and the nature of the venous vessels in the splenic cords (venules or sinuses. The main quantitative feature is the proportion between red and white pulp. Moreover, a phylogeny of this organ is proposed: from a ‘primitive type’ with closed circulation (characteristic of monotremes, insectivores and tree shrews, the spleen has evolved into an ‘archetypal type’ with open circulation (peculiar to mice, gerbils, bats and marsupials. It has subsequently diversified into different models: blood-storing spleens (ungulates and carnivores and defensive spleens (Old World monkeys and the majority of rodents.

    Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group. CT vascular studies of patients with idiopathic intracranial hypertension with pulsatile tinnitus (n = 42), without pulsatile tinnitus (n = 37), and controls (n = 75) were independently reviewed for the presence of severe transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence according to published criteria. The prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence in patients with idiopathic intracranial hypertension with pulsatile tinnitus was compared with that in the nonpulsatile tinnitus idiopathic intracranial hypertension group and the control group. Further comparisons included differing degrees of transverse sinus stenosis (50% and 75%), laterality of transverse sinus stenosis/sigmoid sinus diverticulum/dehiscence, and ipsilateral transverse sinus stenosis combined with sigmoid sinus diverticulum/dehiscence. Severe bilateral transverse sinus stenoses were more frequent in patients with idiopathic intracranial hypertension than in controls (P intracranial hypertension group. Sigmoid sinus dehiscence (right- or left-sided) was also more common in patients with idiopathic intracranial hypertension compared with controls (P = .01), but there was no significant association with pulsatile tinnitus within the idiopathic intracranial hypertension group. While our data corroborate previous studies demonstrating increased prevalence of sigmoid sinus diverticulum/dehiscence and transverse sinus stenosis in

    A compromised overview of surgical techniques regarding the nose (functional) and para nasal sinus inflammation surgical treatment is exposed in this article. The nasal septum is within the focus for function, form and stability for the nasal structure (especially for tip and back of the nose) and for success of a rhinoplasty. An important role play the lower nasal turbinates regulating nasal air flow and thus having a great effect after turbinate surgery (submucosal resection and lateral fracturing).The endonasal endoscopy is of utmost importance for diagnosis, therapy and detection of recurrence. In severe cases of nasal polyps, functional endoscopic sinus surgery (FESS) remains the ultimate therapy. However, the indication to operate will be carried out after exhaustion of medical treatment. The most important recurrent prophylaxis for rhino sinusitis and nasal polyps is an appropriate post operative nasal care. © Georg Thieme Verlag KG Stuttgart · New York.

The total cure rate was 81.82%, effective rate was 92.73%. The mean period of epithelization after operation was 13.2 weeks. No serious complication occurred. The treatment efficacy can be greatly improved by the normative combined therapy which include the standard and orderly perioperative treatment ,the overall shape and nasalization of nasal cavity, postoperative follow-up and clearing cav ity after ESS.

  6. Miller Fisher syndrome with sinus arrest

    Full Text Available Dysautonomia in Guillain-Barre syndrome (GBS rarely causes serious cardiovascular complications, such as sinus arrest. Miller Fisher syndrome (MFS is recognized as a variant of GBS. There have been few reports regarding the association between MFS and dysautonomia. We describe a case of a 68-year-old man with ophthalmoplegia, bulbar palsy, truncal ataxia, and areflexia. He was diagnosed with MFS because he exhibited the classical clinical triad and had elevated serum anti- GQ1b immunoglobulin G levels. A magnetic resonance imaging scan of his head was normal. His 24-hour Holter recording showed sinus arrest. He was treated with intravenous immunoglobulin, whereupon his symptoms gradually improved. This included the sinus arrest, which was considered a symptom of dysautonomia in MFS. Therefore, clinicians should be mindful of dysautonomia not only in GBS patients, but also in cases of MFS.

    We describe an interactive, intraoperative imaging-guided method for performing endoscopic sinus surgery (ESS) within a vertically open MR system. The procedure was performed with intraoperative imaging using a 0.5-T magnet with a 56-cm vertical gap. Interactive control of imaging planes was accomplished by optical tracking with two infrared light-emitting diodes mounted on an aspirator probe. The probe's position defined the location of the orthogonal imaging planes. Twelve patients with varying degrees of sinus disease underwent ESS with MR imaging guidance. Patients had acute and chronic sinusitis, nasal polyposis causing airway obstruction, or tumor requiring tissue biopsy. All procedures were performed with the patients under general anesthesia. The integration of endoscopy with optical tracking and intraoperative interactive imaging allowed localization of anatomic landmarks during ESS. No complications were encountered.

    Chronic sinusitis is one of the most common otolaryngological diagnoses. Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis can easily be misdiagnosed and treated as chronic sinusitis, causing continuing harm. To better identify and characterise these two subgroups of patients, who may suffer from a systemic disease requiring multidisciplinary treatment and prolonged follow up. A retrospective, longitudinal study of all patients diagnosed with allergic fungal sinusitis or eosinophilic mucin rhinosinusitis within one otolaryngology department over a 15-year period. Thirty-four patients were identified, 26 with eosinophilic mucin rhinosinusitis and 8 with allergic fungal sinusitis. Orbital involvement at diagnosis was commoner in allergic fungal sinusitis patients (50 per cent) than eosinophilic mucin rhinosinusitis patients (7.7 per cent; p sinusitis patients. Allergic fungal sinusitis and eosinophilic mucin rhinosinusitis have the same clinical presentation but different clinical courses. The role of fungus and the ability to confirm its presence are still problematic issues, and additional studies are required.

    Moore, Brandon; Dasi, Lakshmi Prasad

    2014-07-01

    The aortic sinus vortex is a classical flow structure of significant importance to aortic valve dynamics and the initiation and progression of calcific aortic valve disease. We characterize the spatiotemporal characteristics of aortic sinus vortex dynamics in relation to the viscosity of blood analog solution as well as heart rate. High-resolution time-resolved (2 kHz) particle image velocimetry was conducted to capture 2D particle streak videos and 2D instantaneous velocity and streamlines along the sinus midplane using a physiological but rigid aorta model fitted with a porcine bioprosthetic heart valve. Blood analog fluids used include a water-glycerin mixture and saline to elucidate the sensitivity of vortex dynamics to viscosity. Experiments were conducted to record 10 heart beats for each combination of blood analog and heart rate condition. Results show that the topological characteristics of the velocity field vary in timescales as revealed using time bin-averaged vectors and corresponding instantaneous streamlines. There exist small timescale vortices and a large timescale main vortex. A key flow structure observed is the counter vortex at the upstream end of the sinus adjacent to the base (lower half) of the leaflet. The spatiotemporal complexity of vortex dynamics is shown to be profoundly influenced by strong leaflet flutter during systole with a peak frequency of 200 Hz and peak amplitude of 4 mm observed in the saline case. While fluid viscosity influences the length and timescales as well as the introduction of leaflet flutter, heart rate influences the formation of counter vortex at the upstream end of the sinus. Higher heart rates are shown to reduce the strength of the counter vortex that can greatly influence the directionality and strength of shear stresses along the base of the leaflet. This study demonstrates the impact of heart rate and blood analog viscosity on aortic sinus hemodynamics.

  12. Evolution of the paranasal sinuses' anatomy through the ages

    2013-01-01

    Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was first to describe the maxillary sinus. PMID:24386595

    Full Text Available Carotid sinus hypersensitivity is a common cause of fainting and falls in the elderly, and can be diagnosed by carotid sinus massage. We present a 67-year-old diabetic man who was admitted with hyperglycemia. During thyroid examination, clouding of consciousness occurred with unilateral palpation. Asystole was documented for 4.8 seconds and suspected for 7 seconds upon carotid sinus massage. A cardioverter defibrillator was implanted. Carotid sinus hypersensitivity should be kept in mind when examining diabetic patients.

    Objective Intubation is a risk factor for nosocomial sinusitis in adult intensive care patients. Sinusitis in intubated adults can be an occult cause of fever. In children nasal intubation may be associated with a greater risk of sinusitis. No pediatric study has determined the incidence of nosocomial sinusitis in the pediatric intensive care unit (PICU) setting. We hypothesized that within a subset of patients who had head CT imaging: (1) the incidence of sinusitis in PICU patients exceeds the incidence in non-PICU patients; (2) the incidence of sinusitis is greater in PICU patients with a tube (nasotracheal, nasogastric, orotracheal, or orogastric); and (3) nasal tubes confer an increased risk for sinusitis compared to oral tubes. Design Retrospective chart review Setting Independent not-for-profit pediatric healthcare system Patients PICU and non-PICU (inpatients hospitalized on medical-surgical wards) patients referred for head CT Interventions None Measurements and Main Results CT images were evaluated for the presence of a tube and sinusitis. Images were scored using the Lund-MacKay (LM) staging system. Sinusitis was defined as a LM score >3.5. 596 patients were studied; 395 (66.3%) PICU. 197 (50%) PICU versus 69 (34.3%) non-PICU patients had sinusitis (p sinusitis versus 88/248 (35.9%) of those without a tube present (p sinusitis based on tube location (p=0.218). Younger age or the presence of a tube increased the probability of sinusitis (p sinus disease had evidence of sinusitis. This finding raises the concern that sinusitis in PICU patients is common and likely should be considered in the differential diagnosis of fever in PICU patients. PMID:21283043

    As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism. But this kind of sinus

    Radicular cysts (RCs) are the most common inflammatory jaw cystic lesions that occur infected and necrotic in teeth pulps. They account for more than 50% of all odontogenic cysts. Radicular cysts cause slowly progressive painless swelling. There are no symptoms until they become large. Enucleating the cyst is recommended with primary treatment. Here we describe a patient with a large RC with maxillary sinus involvement who underwent an endonasal endoscopic approach for complete resection. In conclusion, the endonasal endoscopic approach should be kept in mind for the resection of RC with maxillary sinus involvement because of its minimally invasive characteristics.

    Inappropriate sinus tachycardia (IST) is a clinical syndrome lacking formal diagnostic criteria. It is generally defined as an elevated resting heart rate (HR; >90-100 bpm) with an exaggerated response to physical or emotional stress and a clearly sinus mechanism. Clinical manifestations are broad from a complete lack of symptoms to incapacitating incessant tachycardia. Now understood to be relatively prevalent, it is observed to have a generally benign prognosis, though symptoms may persist for years. Whether IST is a single discrete entity or a heterogeneous condition with overlap to other syndromes such as postural orthostatic tachycardia syndrome remains a matter of debate.

    The purpose of this study is to describe the clinical and histopathological features, management and outcome of a series of patients with simultaneous occurrence of invasive and non-invasive fungal sinusitis (mixed fungal sinusitis). The histopathological records of patients with fungal sinusitis seen over the last 6 years were reviewed. The clinical, histopathological, treatment and follow up details of all cases with mixed fungal sinusitis were noted. Six cases of mixed fungal sinusitis with concurrent occurrence of chronic granulomatous fungal sinusitis and allergic fungal sinusitis (AFS) were seen during the study period. Most (83.3 %) had bilateral disease. All patients had undergone prior endoscopic sinus surgery at least once within the previous 2 years. Histopathological features showed predominance of invasive disease in half the patients. Except for one patient who did not report for follow up, all patients with predominant chronic granulomatous fungal sinusitis received systemic antifungal therapy and inhaled steroids. Those with predominant features of AFS received oral and inhaled steroids. Five patients with mixed fungal sinusitis who had follow up ranging from 6 months to 5 years were disease free following treatment. Mixed fungal sinusitis should be recognized by the surgeon and pathologist as a separate category of fungal sinusitis whose treatment depends on accurate histological diagnosis. A good outcome may be expected with appropriate therapy.

    Full Text Available Introduction & Objective: Because of widespread use of Functional Endoscopic Sinus Surgery (FESS technique and basic role of coronal CT- Scan in understanding of normal drainage route of Para-nasal sinuses, identifying the major patterns of inflammatory sinonasal disease and accompanied anatomical variations is crucial for appropriate preoperative surgical planning. The purpose of this study was to determine the incidence of major inflammatory patterns and accompanied anatomical variations in patients with chronic inflammatory sinonasal disease that underwent FESS in different hospitals of Hamadan during 2000- 2004.Materials & Methods: This prospective descriptive study was carried out on coronal CT- Scans of 385 patients with chronic inflammatory sinonasal disease that underwent FESS. Patients with clinical signs of chromic rhinosinusitis were diagnosed by otolaryngologist and after 3- 6 weeks of medical therapy if appropriate clinical response were not achieved, coronal and if needed axial CT-Scan were taken from them. CT-Scans were taken mainly in bone and intermediate windows and if soft tissue masses except than polyposis were suspected soft tissue windows were taken too. CT-Scans were reported by radiologist and inflammatory patterns and accompanied anatomical variations with clinical and demographic information were analyzed. Results: In 385 cases major inflammatory pattern included: infundibular 11.1%, osteomeatal unit 37.6%, sphenoethmidal recess 21.2%, sinonasal polyposis 18.9% and sporadic 24.4% . These patterns were seen solely or as a combinations and so total percent was more than 100%. Three major obstructive patterns were seen in 70.1% of cases. In 73.2% of cases accompanied anatomical variation including septal deviation (50.6%, concha bullosa (28.5%, extensive pneumatization of sphenoid sinus (17.9%, paradoxic middle turbinate (16.1%, Haller cell (15.5%, giant bulla ethmoidalis (10.3%, athelectatic uncinate process (8.8%, Agger

    Full Text Available Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation. Conclusion. Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery.

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Sick sinus syndrome (SSS) is a dysfunction of sinoatrial node resulting in symptomatic bradycardia or sinus pauses causing decreased cardiac output with cerebral hypoperfusion and usually presents as syncope, presyncope or fatigue. The occurrence of a seizure is very rare. A 69-year-old man suffered two episodes of generalised tonic-clonic seizures. MRI and electroencephalogram failed to reveal the cause of seizures. In the emergency room, he experienced presyncope simultaneous to bradycardia and sinus pauses. He was stabilised with atropine and dopamine infusion and underwent definitive therapy with a permanent dual-chamber pacemaker with complete symptom resolution. Diagnostic confounders include convulsive syncope and ictal bradycardia. Syncope may be accompanied by myoclonic jerks (convulsive syncope), but postictal confusion is absent. Bradycardia may be seen during the postictal period (ictal bradycardia syndrome), but protracted sinus dysfunction is not present. Hypoperfusion due to significant SSS triggered seizures in this patient who may have an underlying predisposition. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Dermal sinus tracts are remnants of incomplete neural tube closure. Dermal sinus tracts in the spine range from asymptomatic pits to tracts with significant disease. Congenital spinal dermal sinus tract can produce significant morbidity if not adequately managed. Spinal subdural abscess caused by the spread of an infection within the dermal sinus tract is rare in children. We now described a 3-year-old male who presented with extensive spinal subdural abscess resulting from dermal sinus tract that was low-lying in the sacral area.

    Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

    Evaluation of outcome of pilonidal sinus excision using a radiofrequency device and comparing its results with excision and open granulation procedure. Patients with sacro-coccygeal pilonidal sinus disease (n=44) were randomly assigned to undergo either a wide excision and healing by open granulation procedure [WEG] (n=23) or a radiofrequency sinus excision [RSE] (n=21). An Ellman radiofrequency generator was used for RSE. Intra- and postoperative events and outcome data were evaluated and analyzed by Student's unpaired t test and chi(2) test. The significant differences in the two groups WEG and RSE were as follows: mean hospital stay (47 vs. 10 h, p< 0.05), period off work (29 vs. 8 days, p< 0.05), mean analgesic requirement (39 vs. 15 tablets, p< 0.05), time for complete wound healing (84 vs. 49 days, p< 0.05). At the mean follow-up of 30 months, 2 patients from the wide excision and open granulation group and one patient from the radiofrequency sinus excision group developed recurrence. These findings suggest that sinus excision with radiofrequency is a simple and swift procedure. It needs a short hospital stay and is associated with less postoperative pain and early resumption to work. As compared to excision and healing by granulation technique, the radiofrequency sinus excision procedure achieves faster wound healing and a better outcome. Copyright (c) 2005 S. Karger AG, Basel.

    The National Physicians Alliance (NPA)-initiated a project titled "Promoting Good Stewardship in Clinical Practice" to develop a list of the "Top 5" activities in primary care, where changes in practice could lead simultaneously to higher quality care and better use of finite clinical resources. The treatment of acute mild to moderate sinusitis was selected for the "Top 5" list because it is a common clinical problem. Evidence supports avoiding antibiotics early in the course of the illness, and doing so could markedly reduce costs. We reviewed the results of meta-analyses of randomized controlled trials published in the past 10 years comparing antibiotic treatment with placebo and summarized the evidence regarding the benefits, harms, and costs of antibiotic treatment of acute mild to moderate sinusitis. Sinusitis is one of the most common diagnoses in primary care, accounting for 20 million visits annually in the United States and 15% to 21% of annual antibiotic prescriptions. In randomized controlled trials, cure or improvement 7 to 15 days after beginning treatment was statistically significantly more common among patients assigned to antibiotics compared with placebo, but the differences were small, ranging from a 7% to 14% higher rate of improvement with antibiotics. The rate of complications and recurrence did not differ between those treated with antibiotics and placebo. Adverse effects, primarily diarrhea, were 80% more common in the antibiotic compared with the placebo groups. In addition to adverse effects, overuse of antibiotics can also harm population health by increasing rates of antibiotic resistance Antibiotics should not be prescribed for mild to moderate sinusitis within the first week of the illness. Avoiding antibiotics for acute sinusitis could reduce antibiotic adverse effects, antibiotic resistance, and the cost of health care.

    The almost simultaneous introduction of nasal endoscopy and CT imaging led to better understanding of normal and pathologic function of the paranasal sinuses. Diagnosis and treatment of many paranasal sius diseases improved considerably. Endoscopy and CT are not concurrential; they are complementary, but they have specific strengths and weaknesses, as well as specific indicatons and consideratons. Staging systems for chronic sinusitis are currently used based on CT findings and response to medical therapy. Functional endoscopic sinus surgery (FESS) has become the standard procedure for most surgical cases of chronic sinusitis. Indications for FESS have enlarged beyond chronic sinus problems and even beyond the borders of the sinuses. Functional endoscopic sinus surgery aims to gain maximal result (restoring normal function) with minimal trauma and morbidity. (orig.)

    We report an unusual case of a displaced maxillary molar and associated dentigerous cyst within the maxillary sinus in an adolescent presenting as recurrent sinusitis. Although a rare cause of sinusitis in children, dentigerous cysts should be included in the differential diagnosis for causes of persistent or recurrent sinusitis in this age group. This report provides further evidence for obtaining imaging studies when managing pediatric sinusitis that does not respond to standard antibiotic therapy. We discuss management options for these lesions including the differential diagnoses and need for follow-up. (orig.)

    Full Text Available Severe cardiovascular responses in the form of tachycardia and hypertension following nasal speculum insertion occur during sublabial rhinoseptal trans-sphenoid approach for resection of small pituitary tumours. We compare the effects of preoperative administration of clonidine (α-2 agonist and atenolol (α-blocker over haemodynamic response, caused by speculum insertion during trans-sphenoid pituitary resection. We enrolled 66 patients in age range 18-65 years, of ASA I-II, and of either sex undergoing elective sublabial rhinoseptal trans-sphenoidal hypophysectomy. Group I (control received placebo, group II (clonidine received tablet clonidine 5 μg/kg, and group III (atenolol received tablet atenolol 0.5 mg/kg. The heart rate increased on speculum insertion and 5 and 10 minutes following speculum insertion as compared to the pre-speculum values in the control group, while no change in the heart rate was observed in other groups (P<0.05. There was a rise in the mean arterial pressure during and 5, 10, and 15 minutes after nasal speculum insertion in the control group, whereas it was not seen in other groups (P<0.05. We therefore suggest that oral clonidine and oral atenolol (given 2 hours prior to surgery is an equally effective and safe method of attenuating haemodynamic response caused by nasal speculum insertion during trans-sphenoid pituitary resection.

    Full Text Available In maxillary sinusitis pathogenesis researchers paid much attention to the role of paranasal sinuses, sinus drainage dysfunctions, mucocyliary transport system disorders in cases of damage of sinuses mucous membranes. Pathohistological, immunohistochemical and morphometric studies of mucosa were conducted. However, to evaluate the local inflammatory response in cases of chronic sinusitis and improvement of individual therapy for the patients, the immunohistochemical studies of the composition of inflammatory immunocyte infiltrates of paranasal sinus mucosa and adenoid vegetations bioptate would be reasonable. The aim of the research was to study the immunohistochemical content of immunocyte infiltrates of paranasal sinuses adenomatous polyps in biopsy samples of patients suffering from chronic sinusitis. Materials and Methods. Paranasal sinuses adenomatous polyps removed during surgery of 22 patients suffering from chronic maxillary sinusitis were studied. Immunohistochemical studies of paraffin sections of the removed polyps were performed using appropriate primary antibodies and visualization systems DAKO EnVision+ System (DAKO, Denmark. Results. During microscopic investigation of paranasal sinuses adenomatous polyps of the patients suffering from chronic sinusitis, moderate and severe immunocyte infiltration of polyp stroma sometimes with focal follicular structures was presented. Immunohistochemical investigation of the cellular composition of these infiltrates proved the presence of CD8+ T-killer cells, CD4+ T-helper cells, CD68+ macrophages as well as single plasma cells. The irregularity of these cells markers expression was determined in dependence of the severity of inflammatory cell infiltration. Conclusions. In the patients with chronic maxillary polyp sinusitis with mild and moderate immunocyte infiltration of paranasal sinus mucosa, among immune cells the CD4+ T-lymphocytes occupied the most relative area in polyp stroma, plasma

    Full Text Available Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review. Previous meta-analysis showed that survival rates of implants placed in grafted maxillary sinuses had similar survival rates whether autogenous, allogenous, or alloplastic grafts were used. This paper aims to review scientific data on the direct sinus elevation technique without use of any grafting material, volume of new bone formed, and also mechanism behind this technique. Articles were searched from 1997 to October 2014 in PubMed, Google Scholar, and Cochrane CENTRAL. The study eligibility criteria were (1 direct sinus lift procedure without any graft material during implant placement and (2 human or animal studies with a minimum follow-up of 6 months or more. Two authors independently scrutinized the literature and if any controversy was raised, third author's opinion was sought to arrive at a mutual consensus for including the study in the review. Due to the heterogeneity across all studies in all study designs, the data were not pooled and a meta-analysis was not performed. Taking into consideration all factors reviewed in this regard along with the outcomes, the direct sinus lift technique without grafting can be suggested as a viable treatment option keeping in mind the limitations involved. The average bone gain was seen across all studies ranging from 2.37 to 10 mm and with an implant survival rate ranging from 79

    Several experimental studies have shown osteitis after the onset of sinusitis, supporting the idea that bone involvement could participate in the dissemination and perpetuation of this inflammatory disease. However, procedures commonly performed for the induction of sinusitis, such as antrostomies, can trigger sinusitis by themselves. To evaluate osteitis in an animal model of sinusitis that does not violate the sinus directly and verify whether this is limited to the induction side, or if it affects the contralateral side. Experimental study in which sinusitis was produced by inserting an obstructing sponge into the nasal cavity of 20 rabbits. After defined intervals, the animals were euthanized and maxillary sinus samples were removed for semi-quantitative histological analysis of mucosa and bone. Signs of bone and mucosal inflammation were observed, affecting both the induction and contralateral sides. Statistical analysis showed correlation between the intensity of osteitis on both sides, but not between mucosal and bone inflammation on the same side, supporting the theory that inflammation can spread through bone structures, regardless of mucosal inflammation. This study demonstrated that in an animal model of sinusitis that does not disturb the sinus directly osteitis occurs in the affected sinus and that it also affects the contralateral side.

    Chronic sinusitis is one of the most common presenting complaints of all doctor visits in the United States and Europe, with more than 13% of people affected in any given year. This disease has a wide range of impact on communities. Patients with recurrent or chronic sinusitis report a deteriorative sense of general health and vitality, when compared to general population. In our Department we perform about 600 functional endoscopic sinus surgeries (FESS) per year. Chronic rhinosinusitis represents a spectrum of inflammatory and infectious processes concurrently affecting the nose and paranasal sinuses. Among chronic paranasal sinusitis one must single out paranasal sinusitis with and without polyps. In the paranasal sinusitis patomechanism the blockage of natural ostium plays one of the most important roles. The closure of sinus proper ventilation passages leads to the triggering of many pathological occurrences within mucous membrane of this region. The treatment of paranasal sinusitis is diversified and involves a surgical procedure as well as anti-inflammatory and antiallergic drugs (medications) and mucolytics. Its purpose is to clear the nose through the elimination of bacterial infection, liquidating and removal of lying discharge and the restoration of the proper muco-ciliary transportation, and through this the improvement of local condition and faster recovery. In this work the usage of carboxycysteine to treat paranasal sinus conditions has been presented. Copyright © 2012 Polish Otolaryngology Society. Published by Elsevier Urban & Partner Sp. z.o.o.

    Full Text Available Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococcus aureus growth and the child improved with intravenous cloxacillin therapy. This case is presented due to the rarity of its presentation in this age group and for awareness to consider this entity in children having fever and peri-orbital swelling.

    Full Text Available Lateral sinus thrombosis (LST is usually occurs as a complication of middle ear infection .The involvement of lateral sinus during the course of ear infection was a well known complication in preantibiotic days .The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment. Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.

    2009-03-01

    The role of fungi in chronic rhinosinusitis (CRS) is not clear. Fungi can be detected in the nose and paranasal sinuses of virtually all CRS patients; however, they also appear to be present in healthy controls. Various theories attempt to explain the mechanisms by which fungi can exert an effect on sinus mucosa in susceptible individuals. Further studies are necessary to clarify the role of fungi in CRS, which fungal organisms (if any) are pathogenic, and what exactly characterizes the immunologic response to fungi that may result in the development of disease. However, in the absence of convincing immunologic data and evidence of clinical improvement of CRS after antifungal therapy, the case against the fungus remains unproven.

    Mold pathogens are a leading cause of chronic rhinosinusitis. Successful isolation of mold on culture is helpful in establishing a diagnosis and guiding therapy. Though mucolytic agents are commonly used in European countries, they are not part of everyday use in North America. In this case-control prospective study, we investigated the yield of fungal culture before and after treatment of sinus aspirates with the mucolytic agent dithiothreitol in a United States hospital. Over a 5-month period during 2011-2012, 359 sinus aspirates from 294 patients with symptoms suspicious for chronic sinusitis or allergic fungal sinusitis were collected. Aspirates were cultured on fungal medium before and after treatment with dithiothreitol. Of the 359 pairs of cultures, 62 (17.3%) demonstrated mold growth on at least 1 of the plates, 9 (14.5%) of which grew more than 1 species of mold. A total of 75 molds were identified, 41 (54.7%) of which were successfully cultured only when the mucus was pretreated with dithiothreitol (p sinus cultures after pretreatment of samples with dithiothreitol.

    Background: We report the recovery of ophthalmoplegia in 11 patients with cavernous sinus dural arteriovenous fistula (CSDAVF) after sinus packing at follow-up. Methods: Of 18 patients with CSDAVF treated with transvenous cavernous sinus packing between August 2002 and December 2007 at Beijing Tiantan Hospital, there were 9 patients with initial CNIII or CNVI dysfunction and 2 patients with CNVI dysfunction immediately after cavernous sinus packing selected and reevaluated. Results: Of 11 patients with CNIII or CNVI palsy, recovery was complete in 10. In 1 patient, complete CNVI palsy was unchanged because the CSDAVF was not cured. There were 6 men and 5 women with a mean age of 52.9 years. In 5 patients, CNVI palsy was associated with chemosis, proptosis and pulsatile tinnitus. Timing of treatment after onset of symptoms was from 4 to 35 days in 9 patients. All CSDAVFs were Barrow type D. Mean follow-up after treatment was 17.7 months (range, 2-54 months). Conclusion: CSDAVF-induced CNIII or CNVI palsies can be cured after cavernous sinus packing transvenously in most patients.

    Sinus Aestuum is the only known location on the Moon where orbital data have detected Fe-and/or Cr-spinel. We analyzed Moon Mineralogy Mapper (M3) visible to near-infrared data of the largest and strongest spinel signatures and determined that these locations always correspond to impact craters. M3 spectra show that at least three types of spinels may be present, all of which exhibit a strong and broad absorption at 2100 nm, and also one of the following: (1) a narrow 700-750 nm absorption, (2) a broad 600-900 nm absorption, or (3) both a weaker 700 nm and stronger 1000 nm absorption. All the spinel detections occur on either larger highland massifs that make up Sinus Aestuum east and west or smaller highland kīpukas and buried highlands within the mare. Almost all of the spinel signatures occur within the mapped pyroclastic dark mantle deposit (DMD). The strong correlation between spinel and DMD distribution on the highlands at Sinus Aestuum is best explained if the spinels were emplaced during the same explosive eruption(s) that deposited the pyroclastics in the Sinus Aestuum DMD. Our observations are most consistent with models of melt-rock reactions in the anorthositic lunar crust that produce contaminated (high-Al) regions within a volcanic dike or magmatic reservoir that was capable of erupting pyroclastic glass beads containing pleonaste spinel [Mg,Fe]Al2O4. Over billions of years, this surface layer of spinels and pyroclastics became heterogeneously mixed into and partially buried within the highland regolith where younger impact craters may sometimes expose it.

    McCaffrey, T V; McDonald, T J

    1983-10-01

    Sarcoidosis is a chronic systemic disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs. The records of 2319 patients with the diagnosis of sarcoidosis were reviewed to determine the incidence of nasal involvement. Seventeen patients or approximately 1% of the patients with sarcoidosis had histologically proven nasal mucosa involvement. These patients had symptoms of nasal crusting, congestion, epistaxis, pain, or anosmia. The clinical findings in these patients included friable nasal mucosa, nasal polyps, or a characteristic submucosal nodularity. Most patients also had abnormal sinus roentgenograms with either thickening of the sinus mucosa or opacification of the sinuses. Biopsy of the nasal mucosa shows typical non-caseating granulomas, but care must be exercised to exclude other causes of granulomatous inflammation of the nasal mucosa including tuberculosis, fungal infections, and other idiopathic granulomatous diseases such as Wegener's granulomatosis and Churg-Strauss syndrome. The treatment of nasal sarcoidosis has consisted of systemic steroids and in some cases topical beclomethasone dipropionate.

    Since typical inflammatory responses may be diminished in children following bone marrow transplant (BMT), computed tomography (CT) imaging of the sinuses has been increasingly ordered to diagnose sinusitis in this group. The objective of this study was to determine the association between clinical sinusitis symptoms and sinus opacification on CT scans in post BMT versus immunocompetent children. Our sample was comprised of 64 post BMT and 86 immunocompetent children with sinus CT scans. CT sinus opacification was scored using the modified Lund–Mackay staging system. The relationship between clinical sinusitis symptoms (rhinorrhea, nasal congestion, cough, headache, and facial pain) and opacification was compared for the two groups. The severity of sinus opacification in the BMT group was significantly higher compared to the immunocompetent group. In combined patient groups the odds ratio (OR) for moderate/severe sinusitis was significantly elevated for rhinorrhea (OR=3.00; 95% confidence interval [CI], 1.27–7.12), cough (OR=2.80; 95% CI, 1.22–6.42), and having either rhinorrhea, nasal congestion, or cough (OR= 4.76; 95% CI, 1.71–13.24). While the immunocompetent group had a greater number of sinusitis symptoms compared to the post BMT group, both groups had a significant increase in the severity on CT with increasing number of symptoms. Conclusion In post BMT patients, our data demonstrated higher odds of moderate/severe sinusitis on CT scans associated with rhinorrhea, cough or nasal congestion. These finding suggest that in post BMT children, detailed sinus history may still play a vital role in the diagnosis of sinusitis. PMID:21904829

    Gorlin syndrome is an autosomal dominant disorder linked to PTCH1 mutation, identified by a collection of clinical and radiologic signs. We describe the case of a family in which father and son fulfilled clear cut diagnostic criteria for Gorlin syndrome including multiple basal cell carcinomas, keratocystic odontogenic tumors, atypical skeletal anomalies and a novel PTCH1 germline mutation (c.1041delAA). Craniofacial and other skeletal anomalies displayed at 3D and helical CT scan were: macrocephaly, positional plagiocephaly, skull base and sphenoid asymmetry, bifidity of multiple ribs and giant multilocular odontogenic jaw cysts. Extensive multilamellar calcifications were found in falx cerebri, tentorium, falx cerebelli and in the atlanto-occipital ligament. The inclusion of bifid ribs as a novel major criteri may be useful for the recognition and characterization of misdiagnosed cases.

    In the period 1983 to 1985, 66 patients presented to six Japanese university hospitals with squamous cell carcinoma of the maxillary sinus. Using self-administered questionnaires, a case-control study was conducted to examine history of nasal diseases, occupational exposures, and other possible risk factors for this disease. For each patient, two controls were selected from the general population, matched to the patient by sex, age (+/- 5 years), and district of residence. A history of chronic sinusitis was associated with a 2.3-fold increase in risk (p = 0.05). A high relative risk was also observed in males with an occupational history of woodworking or joinery, particularly when these jobs involved sanding or lathing practices (RR = 7.5, p = 0.02). No association between cigarette smoking and maxillary sinus cancer was observed in this study and no evidence was found that indoor air pollution in the home is involved in cancer development.

    Context: Maxillary sinusitis is an important issue in dentistry and maxillofacial surgery. This study aims to present a systematic review of etiologies and treatments of odontogenic maxillary sinusitis. Evidence Acquisition: An electronic database search was performed based on related MeSH keywords. Articles published between January 2001 and December 2014 was selected according to the inclusion criteria. The information extracted from various studies was categorized in various tables. Results: The study selected 19 studies. In most studies, oroantral fistula (OAF) was the most common etiology of odontogenic sinusitis. Alpha-hemolytic streptococcus was the most common flora in sinusitis with dental origin. The literature shows that the Caldwell-Luc approach may be the best method for treating sinusitis in cases of displaced teeth. Conclusions: OAF is a common cause of odontogenic maxillary sinusitis and may easily be treated by endoscopy and fistula closure. Maxillofacial surgeons and dentists should consider this problem to avoid misdiagnosis and prevent complications. PMID:26756016

    2011-10-01

    Full Text Available Mucoceles of the paranasal sinuses are slowly growing, epithelium-lined cystic lesions with sterile content. When the mucocele content becomes infected with a bacterial super-infection, the lesion is defined as mucopyocele. Mucoceles or mucopyoceles are commonly located in the frontal and anterior ethmoidal sinuses and can manifest with ocular signs and symptoms, mostly proptosis. In this report, we demonstrate a case of bilateral ethmoidal mucopyocele in a 53-year-old female who presented with reduced vision, diplopia, and proptosis. Computed tomography (CT scanning of the paranasal sinuses revealed cystic lesions filling the maxillary sinuses and anterior ethmoidal cells bilaterally and causing erosion in the walls of the sinuses. After marsupialization of the mucopyoceles was performed by endoscopic sinus surgery, the symptoms of the patient recovered rapidly. (Turk J Ophthalmol 2011; 41: 354-6

We also included an in-depth literature review. Methods: We retrospectively reviewed the medical files of 51 patients from January 2008 to January 2014. The records were evaluated for age, gender, type of orbital complications, symptoms, predisposing factors, imaging studies, medical and surgical management, culture results, and follow-up information. SPSS version 15.0 software (Statistical Analysis, The Statistical Package for Social Sciences Inc, Chicago, IL was used for the statistical analysis. Results: Fifty-one patients met the criteria, with available medical records, for the study (29 male, 22 female. Thirty-two (62.7% were diagnosed with preseptal cellulitis and 19 (37.3% with postseptal cellulitis. After a detailed evaluation, 15 were diagnosed with a subperiosteal abscess (SPA, and 4 were diagnosed with orbital cellulitis. The age and gender was similar for the two groups. Five patients with medial SPA were treated with endoscopic sinus surgery, one patient with inferior SPA was treated with external surgery, and six patients with other localizations were treated with a combination of endoscopic sinus surgery and external surgery. All patients presented with periorbital erythema and edema. The length of hospitalization and duration of symptoms were similar in both groups. Visual acuity was between 1/10 to 10/10 (mean 7/10 and statistically significant for preseptal and postseptal cellulitis groups (p<0.001. All patients received intravenous antibiotics upon the first day of admission. Conclusion: Orbital complications of acute sinusitis required intensive follow-up and a multidisciplinary approach. A contrast-enhanced paranasal sinus computerized tomography (CT scan can detect the extent of the infection. An initial trial of intravenosus (IV antibiotics may be appropriate when

    Various sinus augmentation procedures, using bone substitutes, have been used to place dental implants in the atrophic posterior maxilla. The aim of this article is to evaluate the possibility of new bone formation in the maxillary sinus without a bone graft. Ten patients without significant sinus pathosis were selected for this study. The bony window was prepared in the lateral wall using the ultrasonic piezoelectric bone surgery device (Surgybone, Silfradent srl, Sofia, Italy). The sinus membrane was elevated superiorly and implants were placed simultaneously to maintain the space under the sinus membrane for new bone formation. As the methods of sealing the lateral access window of the sinus, patients were divided into 2 groups. Nonresorbable membrane was used to seal the lateral access window of the maxillary sinus after implant placement in 5 cases (group A). Replaceable bony window was used to seal the lateral wall of the sinus in another 5 cases (group B). Computed tomograms were taken immediately before and after surgery, at the uncovering of the implant, and after a 6 month healing period. A bone biopsy was taken on the previous bony window area to evaluate new bone formation. A total of 21 implants in lengths of 10 to 15 mm (mean, 13 mm) were placed, with an average residual bone height of 5 mm (range, 1-9 mm). All implants remained stable during the study period in clinical evaluations. New bone formation and new sinus floors were found in radiographic and histologic evaluations. The human study showed the capacity of new bone formation in the maxillary sinus with membrane elevation only and simultaneous implant placement beyond the original sinus floor. New bone formation without additional bone graft in the maxillary sinus is revealed from the clinical, radiographic, and histologic results, but furthermore long-term studies are needed to confirm this.

    Low-grade osteosarcomas of the paranasal sinus are extremely rare. Most reported cases of maxillary sinus osteosarcoma are high-grade. We present a 51-year-old man with a low-grade osteosarcoma which was histologically difficult to diagnose in isolation since it had bland features. The presence of an aggressive destructive lesion on imaging influenced the final pathological diagnosis as often appears to be the case with this rare tumor.

    The CT scores and scoring for improvement based on them, which we proposed previously, is a simple and highly reproducible method of evaluation of sinus units before and after an operation for chronic sinusitis. We compared this evaluation method with the results of quantitative assay and showed its advantages and disadvantages. The subjects were 258 sinuses in patients who underwent endonasal sinus surgery (ESS) in the department of otolaryngology, Kyoto Prefectural University of Medicine Hospital from April 1996 to April 1997. The subjects were evaluated according to the following 4 grades negligible shadow in the paranasal sinus CT scored 0, less than 50% shadow scored 1, more than 50% of shadow scored 2, and mostly filled with shadow scored 3. Furthermore, the preoperative and postoperative CT scores were compared and the rate of improvement was rated in the following 3 grades: score 0 for unchanged or aggravated subjects, score 1 for subjects showing improved CT score by 1 grade, and score 2 for those showing improved CT score by 2 grades or a postoperative CT score of 0. Quantitative image analysis was input into a personal computer and the ratio occupied by the shadow was calculated, as the shadow ratio. While some discrepancies were seen in parts in the comparison of the quantitative image analysis and CT scores as the former captures minute shadows, a positive correlation was obtained overall. Attention is needed to accurately evaluate small paranasal sinuses such as the frontal sinus, and small amounts of shadow, which are areas where errors may occur. A satisfactory correlation was obtained between the score for the improvement rate and the difference in the shadow ratios before and after surgery. The CT scores and the scores for the improvement rate showed no difference from the results of other evaluation methods reported in the past, and evaluation of similar precision was possible. It was thought that this simple evaluation method of CT findings in

    Streptococcus pneumoniae is a major cause of pneumonia and sinusitis. Pneumonia kills >1 million children annually, and sinusitis is a potentially serious pediatric disease that increases the risk of orbital and intracranial complications. Although pneumococcal conjugate vaccine (PCV) is effective against invasive pneumococcal disease, its effectiveness against pneumonia is less consistent, and its effect on sinusitis is not known. We compared hospitalization rates due to sinusitis, pneumonia, and empyema before and after sequential introduction of PCV7 and PCV13. All children 0 to sinusitis, pneumonia, or empyema in Stockholm County, Sweden, from 2003 to 2012 were included in a population-based study of hospital registry data on hospitalizations due to sinusitis, pneumonia, or empyema. Trend analysis, incidence rates, and rate ratios (RRs) were calculated comparing July 2003 to June 2007 with July 2008 to June 2012, excluding the year of PCV7 introduction. Hospitalizations for sinusitis decreased significantly in children aged 0 to sinusitis and pneumonia in children aged 0 to sinusitis and 19% lower risk of hospitalization for pneumonia in children aged 0 to <2 years, in a comparison of 4 years before and 4 years after vaccine introduction.

    Sinusitis is one of the most common diagnoses among adults in ambulatory care, accounting for 15% to 21% of all adult outpatient antibiotic prescriptions. However, the role of antibiotics for sinusitis is controversial. To assess the effects of antibiotics in adults with acute maxillary sinusitis by comparing antibiotics with placebo, antibiotics from different classes and the side effects of different treatments. We searched CENTRAL 2013, Issue 2, MEDLINE (1946 to March week 3, 2013), EMBASE (1974 to March 2013), SIGLE (OpenSIGLE, later OpenGrey (accessed 15 January 2013)), reference lists of the identified trials and systematic reviews of placebo-controlled studies. We also searched for ongoing trials via ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP). We imposed no language or publication restrictions. Randomised controlled trials (RCTs) comparing antibiotics with placebo or antibiotics from different classes for acute maxillary sinusitis in adults. We included trials with clinically diagnosed acute sinusitis, confirmed or not by imaging or bacterial culture. Two review authors independently screened search results, extracted data and assessed trial quality. We calculated risk ratios (RRs) for differences between intervention and control groups in whether the treatment failed or not. All measures are presented with 95% confidence intervals (CIs). We conducted the meta-analyses using either the fixed-effect or random-effects model. In meta-analyses of the placebo-controlled studies, we combined data across antibiotic classes. Primary outcomes were clinical failure rates at 7 to 15 days and 16 to 60 days follow-up. We used GRADEpro to assess the quality of the evidence. We included 63 studies in this updated review; nine placebo-controlled studies involving 1915 participants (seven of the studies clearly conducted in primary care settings) and 54 studies comparing different classes of antibiotics (10 different comparisons

    Chondrosarcomas are malignant tumors of the cartilage that rarely involve the sinonasal region. Here, we describe a case of histologically verified naso-sinus chondrosarcoma in a 40-year-old female presenting with nasal stuffiness and anosmia. The tumor presented on computed tomography (CT) as an expanding soft tissue mass with bone destruction and pressure erosion. The magnetic resonance images (MRI) of the tumor demonstrated high signals on T2-weighted images with nodular and papillary enhancement along the periphery on T1-weighted images with contrast enhancement. The presence of these typical imaging features should be very helpful in diagnosing chondrosarcoma involving the sinonasal region.

    The aim of this clinical investigation was to evaluate the clinical and radiologic outcomes of a single-step surgical procedure that includes functional endoscopic sinus surgery (FESS) and maxillary sinus elevation by the lateral window approach in patients with reversible contraindications to sinus elevation. Thirty-eight patients with insufficient bone height in the posterior maxilla caused by pneumatization of the sinus and with reversible ear-nose-throat (ENT) contraindications to sinus elevation were recruited for this investigation between January 2010 and January 2012. All patients were treated in a single session under general anesthesia for a total of 69 consecutive sinus augmentations. FESS was performed by an ENT specialist, and an oral surgeon carried out sinus elevation through the lateral window approach. Particulate xenograft was used beneath the sinus membrane. Intraoperative and postoperative complications (eg, membrane tears, rhinosinusitis, graft infection or loss) were reported. Nasal endoscopies were performed at 7, 14, and 30 days and 3 months after treatment. After a healing period of 6 months, 137 implants were inserted. Computed tomography scans were performed after 6 months and 1 year. Intraoperative membrane perforation occurred in only one case. No implant failures were recorded during the follow-up period. Radiologic and clinical findings showed the resolution of ENT disease and good bone graft integration after 1 year. A relapse of mucosal thickening observed in some patients did not influence the graft healing. Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

    2017-10-27

    Odontogenic causes of sinusitis are frequently missed; clinicians often overlook odontogenic disease whenever examining individuals with symptomatic rhinosinusitis. Conventional treatments for chronic rhinosinusitis (CRS) will often fail in odontogenic sinusitis. There have been several recent developments in the understanding of mechanisms, diagnosis, and treatment of odontogenic sinusitis, and clinicians should be aware of these advances to best treat this patient population. The majority of odontogenic disease is caused by periodontitis and iatrogenesis. Notably, dental pain or dental hypersensitivity is very commonly absent in odontogenic sinusitis, and symptoms are very similar to those seen in CRS overall. Unilaterality of nasal obstruction and foul nasal drainage are most suggestive of odontogenic sinusitis, but computed tomography is the gold standard for diagnosis. Conventional panoramic radiographs are very poorly suited to rule out odontogenic sinusitis, and cannot be relied on to identify disease. There does not appear to be an optimal sequence of treatment for odontogenic sinusitis; the dental source should be addressed and ESS is frequently also necessary to alleviate symptoms. Odontogenic sinusitis has distinct pathophysiology, diagnostic considerations, microbiology, and treatment strategies whenever compared with chronic rhinosinusitis. Clinicians who can accurately identify odontogenic sources can increase efficacy of medical and surgical treatments and improve patient outcomes.

    In everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results. We couldn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate. CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis. (author)

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean{+-}SD; 19.72{+-}0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study. (orig.)

    2014-08-01

    Cavernous sinus angioleiomyoma (ALM) is extremely rare. Only three cases have been reported to be cavernous sinus ALM, and very few reports described characteristic findings for intracranial ALMs in detail. We report a new case of cavernous sinus ALM, with detailed information on the clinical presentation, radiology, pathology, and surgical approach. A 52-year-old woman had a 6-month history of right eye discomfort. Magnetic resonance imaging showed a right cavernous sinus tumor with heterogenous blush enhancement. Enhanced computed tomography scans and angiography showed small nodular enhancement in the tumor. Complete tumor resection was achieved via an extradural temporopolar approach. ALM was identified based on histologic examination. Intracranial ALMs are different from the ALMs that occur in the extremities based on our review of the literature. Intracranial ALMs appear more frequently in men than women. The cavernous type was the most common pathologically, and they occur often in the epiperidural location. Because cavernous sinus ALM occurs in the interdural space, an epidural approach should be selected. Therefore, it is important to include cavernous sinus ALM into a differential diagnosis of a cavernous sinus tumor. The blush enhancement and nodular enhancement within this lesion may be useful to distinguish cavernous sinus ALM from other differential diagnoses.

    Aspergilloma of the paranasal sinus is a non-invasive form of aspergillosis, most often in the maxillary sinus. This case presents an 86-year-old female with aspergilloma of the left maxillary sinus. The patient's chief complaint was intermittent pain on the left maxillary first premolar area. A radiopacification of the left maxillary sinus was observed on the panoramic radiograph. Cone-beam computed tomography revealed complete radiopacification of the left maxillary sinus and scattered multiple radiopaque mass inside the lesion. Biopsy was performed under local anesthesia. On microscopic examination, numerous fungal hyphae, which branch at acute angle, were observed. The diagnosis was made as an aspergilloma based on the histopathologic examination.

    2014-01-01

    Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

    We present a case of angiographically confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an iso signal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

    The most common reason of orbital infections is sinusitis. Orbital complications of sinusitis are mostly seen in children. Loss of vision and intracranial infections are among the complications of sinusitis. Prompt diagnosis and treatment is very important in the management of orbital complications. The orbital complication can be in the form of cellulitis or abscess. A retrospective review of 26 pediatric patients with orbital complications due to sinusitis was presented in this study. Of 26 patients, there were 13 cases of preseptal cellulitis, 2 cases of orbital cellulitis, and 11 cases of subperiosteal abscess. We grouped the preseptal and orbital cellulites in one category and the subperiosteal abscess in the other. All patients in the cellulitis group recovered by medical treatment. All the patients were treated by surgical drainage. Early diagnosis and appropriate treatment method are vital for the treatment of orbital complications secondary to sinusitis.

    2013-01-01

    People with cystic fibrosis (CF) sinus disease have developmental sinus abnormalities with airway bacterial infection, inflammation, impaired mucociliary clearance and thick obstructive mucus. The pathophysiology of airway disease in CF is not completely understood, and current treatments in CF sinus disease ameliorate symptoms but do not provide a cure. This manuscript reviews the history of CF, its manifestations in sinus disease, and the potential impact and relationship of CF on the upper and lower airway. We discuss recent discoveries in the pathophysiology of CF using the CF porcine animal model and exciting treatments that address the primary gene defect that may translate into improved outcomes in CF and non-CF sinusitis in humans.

    Carotid cavernous sinus fistulas are abnormal communications between the carotid system and the cavernous sinus. Several classification schemes have described carotid cavernous sinus fistulas according to etiology, hemodynamic features, or the angiographic arterial architecture. Increased pressure within the cavernous sinus appears to be the main factor in pathophysiology. The clinical features are related to size, exact location, and duration of the fistula, adequacy and route of venous drainage and the presence of arterial/venous collaterals. Noninvasive imaging (computed tomography, magnetic resonance, computed tomography angiography, magnetic resonance angiography, Doppler) is often used in the initial work-up of a possible carotid cavernous sinus fistulas. Cerebral angiography is the gold standard for the definitive diagnosis, classification, and planning of treatment for these lesions. The endovascular approach has evolved as the mainstay therapy for definitive treatment in situations including clinical emergencies. Conservative treatment, surgery and radiosurgery constitute other management options for these lesions. PMID:23671750

    Full Text Available In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster–Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis. The risk factors found on evaluation were Vitamin B12 deficiency and hyperhomocysteinemia. On optic fundus examination, she had swollen optic disc on the right side with normal fundus on the left side, confirmed with the orbital ultrasound B-scan and optic coherence tomography. Her magnetic resonance imaging showed features of raised intracranial pressure with thrombosis of the superior sagittal and bilateral lateral sinus thrombosis. She was treated with anticoagulation (heparin followed by oral anticoagulants, antiedema measures, and vitamin supplementation for hyperhomocysteinemia. She improved over time and was asymptomatic during follow-up. We discuss the possible mechanisms described in the literature for unilateral papilledema. This report highlights the need for carefully performing bilateral fundus examination so as not to miss the vision or life-threatening causes of a headache.

    Allergic fungal sinusitis (AFS) is a condition that has an allergic basis caused by exposure to fungi in the sinonasal tract leading to chronic inflammation. Despite standard treatment modalities, which typically include surgery and medical management of allergies, patients still have a high rate of recurrence. Subcutaneous immunotherapy (SCIT) has been used as adjuvant treatment for AFS. Evidence exists to support the use of sublingual immunotherapy (SLIT) as a safe and efficacious method of treating allergies, but no studies have assessed the utility of SLIT in the management of allergic fungal sinusitis. A record review of cases of AFS that are currently or previously treated with sublingual immunotherapy from 2007 to 2011 was performed. Parameters of interest included serum IgE levels, changes in symptoms, Lund-McKay scores, decreased sensitization to fungal allergens associated with AFS, and serum IgE levels. Ten patients with diagnosed AFS were treated with SLIT. No adverse effects related to the use of SLIT therapy were identified. Decreases in subjective complaints, exam findings, Lund-McKay scores, and serum IgE levels were observed. Thus, sublingual immunotherapy appears to be a safe adjunct to the management of AFS that may improve patient outcomes. © The Author(s) 2015.

    2009-04-15

    Background: The optimization of radiological examinations is important in order to reduce unnecessary patient radiation exposure. Purpose: To perform a comprehensive optimization process for paranasal sinus radiography at Mikkeli Central Hospital (Finland). Material and Methods: Patients with suspicion of acute sinusitis were imaged with a Kodak computed radiography (CR) system (n=20) and with a Philips digital radiography (DR) system (n=30) using focus-detector distances (FDDs) of 110 cm, 150 cm, or 200 cm. Patients' radiation exposure was determined in terms of entrance surface dose and dose-area product. Furthermore, an anatomical phantom was used for the estimation of point doses inside the head. Clinical image quality was evaluated by an experienced radiologist, and physical image quality was evaluated from the digital radiography phantom. Results: Patient doses were significantly lower and image quality better with the DR system compared to the CR system. The differences in patient dose and physical image quality were small with varying FDD. Clinical image quality of the DR system was lowest with FDD of 200 cm. Further, imaging with FDD of 150 cm was technically easier for the technologist to perform than with FDD of 110 cm. Conclusion: After optimization, it was recommended that the DR system with FDD of 150 cm should always be used at Mikkeli Central Hospital. We recommend this kind of comprehensive approach in all optimization processes of radiological examinations.

    This hundred and sixteen patients with carcinoma of the maxillary sinus received primary therapy consisting of external beam irradiation alone or in combination with surgery and/or chemotherapy at the Department of Radiology, Tokyo Medical and Dental University Hospital, between 1953 and 1982. In our institution, methods of treating cancer of the maxillary sinus have been changed from time to time and showed different control rates and clinical courses. An actuarial 10-year survival rate of 21% has been obtained by the megavoltage irradiation alone as well as 34% actuarial 10-year survival rate by megavoltage irradiation with surgery. After the introduction of conservative surgery followed by conventional trimodal combination therapy, the local control rate has been improved. The amount of functional, cosmetic, and brain damages have been remarkably decreased by this mode of therapy. The actuarial five year survival rate was 67%. In addition, along with the improvement of the local control rate, the control of nodal and distant organ metastases have been emerging as one of the important contributions to the prognosis of this disease.

    A balloon has been developed that completely fills the choana, preventing water from leaking into the pharynx even when the water is entering into the nasal cavity at a rate of 1000 ml per minute. The balloon enables endoscopic sinus surgery (ESS) to be safely performed in "flowing water". This surgical technique is similar to that used in transurethral resections of the prostate because the tip of the endoscope is kept clean, and blood, debris and resected tissues are continuously removed by the water flow. In addition, the water pressure helps to suppress bleeding. This technique enables ESS to be performed with greater ease and efficiency. We have performed ESS in flowing water on 38 patients with chronic sinusitis under local anaesthesia. No complications, such as water leakage into the pharynx, were encountered, and only a few patients felt discomfort from the insertion of the balloon. Even if the balloon had burst, an emergency could have been easily prevented by withdrawing the endoscope from the nasal cavity and stopping the flow of water. Ultrasonography (USG) was used to examine the water-filled nasal cavity during surgery (SSD-2000 and Micro Tip Radial (ASU-101); Aloka, Ltd., Japan). Using USG, the middle turbinate, the inferior turbinate and the nasal septum could be visualized in a single coronal image. When the sensor was in the posterior ethmoid sinus, the orbit and its optic nerve could also be visualized. Since this surgery is performed under local anesthesia, eye movements can rapidly alter the position of the optic nerve. Thus, visualization of the optic nerve's exact position is extremely important. Unfortunately, USG is not very useful for localizing structures and guiding the surgeon to distant tumors or cysts located behind thick bones, since ultrasound can not penetrate hard masses or bones. In this situation, navigation systems are more reliable than USG. Nevertheless, USG is often useful for depicting surgical sites, especially during a

    We present the largest reported cohort of carotid cavernous aneurysms (CCA), comparing the neuro-ophthalmic presentation, complications, and outcome with and without endovascular treatment. Retrospective review of 185 patients with 206 CCAs examined between 1980 and 2001 at a tertiary neuro-ophthalmology and neurovascular service. Patients' symptoms and findings at presentation were recorded and compared with those at outcome. The effect of treatment on outcome and on complication rate was analyzed using the chi test, multivariate analysis of covariance, model-selection log-linear analysis, and multinomial logistic regression. Long-term follow-up was available for 189 of 206 CCAs. Seventy-four CCAs underwent treatment (endovascular, 67 [91%]; surgical treatment, 6 [9%]), and 115 were followed for an average of 4 years, two of which required later treatment. Treatment reduced the incidence and severity of pain, even after adjusting for the severity of initial pain (F(1,192 = 9.59, P = 0.002). Treatment did not significantly affect the patient's final diplopia after adjusting for their initial diplopia (F(1, 182 = 2.01, P = 0.158). Statistical examination revealed that the treated group had a higher proportion of neurological and visual complications than people who were not treated (2(2). = 25.26, P = 0.0003). Endovascular treatment of carotid cavernous aneurysms leads to a significantly higher rate of pain resolution compared with untreated patients, even after adjusting for initial pain severity. Diplopia may not resolve after treatment. The results of this study underscore our approach indicating treatment only in cases of debilitating pain, visual loss from compression, or diplopia in primary gaze or in patients with risk factors for major complications such as pre-existing coagulopathy or sphenoid sinus erosion.

    Objective Three-dimensional anatomical appreciation of the matrix of the cavernous sinus is one of the crucial necessities for a better understanding of tissue patterning and various disorders in the sinus. The purpose of this study was to reveal configuration of fibrous and adipose components in the cavernous sinus and their relationship with the cranial nerves and vessels in the sinus and meningeal sinus wall. Materials and Methods Nineteen cadavers (8 females and 11 males; age range, 54–89 years; mean age, 75 years) were prepared as transverse (6 sets), coronal (3 sets) and sagittal (10 sets) plastinated sections that were examined at both macroscopic and microscopic levels. Results Two types of the web-like fibrous networks were identified and localized in the cavernous sinus. A dural trabecular network constituted a skeleton-frame in the sinus and contributed to the sleeves of intracavernous cranial nerves III, IV, V1, V2 and VI. A fine trabecular network, or adipose tissue, was the matrix of the sinus and was mainly distributed along the medial side of the intracavernous cranial nerves, forming a dumbbell-shaped adipose zone in the sinus. Conclusions This study revealed the nature, fine architecture and localization of the fine and dural trabecular networks in the cavernous sinus and their relationship with intracavernous cranial nerves and vessels. The results may be valuable for better understanding of tissue patterning in the cranial base and better evaluation of intracavernous disorders, e.g. the growth direction and extent of intracavernous tumors.

    Diagnosing sinusitis remains a challenge for primary care physicians. There is a need for a simple, office-based technique to aid in the diagnosis of sinusitis without the cost and radiation risk of conventional radiologic imaging. We designed a low-cost near-infrared (NIR) device to transilluminate the maxillary sinuses. The use of NIR light allows for greater interrogation of deep-tissue structures as compared to visible light. NIR imaging of 21 patients was performed and compared with computed tomography (CT) scans. Individual maxillary sinuses were scored on a scale from 0 to 2 based on their degree of aeration present on CT and similarly based on the NIR signal penetration into the maxilla on NIR images. Our results showed that air-filled and fluid/tissue-filled spaces can be reasonably distinguished by their differing NIR signal penetration patterns, with average NIR imaging scores for fluid-filled maxillary sinuses (0.93+/-0.78, n=29) significantly lower than those for normal maxillary sinuses (1.62+/-0.57, n=13) (p=0.003). NIR imaging of the sinuses is a simple, safe, and cost-effective modality that can potentially aid in the diagnosis of sinusitis. Long-term, significant device refinement and large clinical trials will be needed to determine the diagnostic accuracy of this technique.

    Neurofibromatosis type 1 (NF1) is a common, autosomal dominant tumor-predisposition disorder that arises secondary to mutations in the tumor suppressor gene NF1. Cephalometry is an inexpensive, readily available and non-invasive technique that is under-utilized in studying the NF1 craniofacial phenotype. An analysis of NF1 cephalometry was first published by Heervä et al. in 2011. We expand here on that first investigation with a larger cohort of adult and pediatric patients affected with NF1 and sought objective insight into the NF1 facies, said to feature hypertelorism and a broad nasal base, from cephalometric analysis. We obtained cephalograms from 101 patients with NF1 (78 adults and 23 children) from two NF1 protocols at the National Institutes of Health. Each subject had an age-, gender- and ethnicity-matched control. We used Dolphin software to make the cephalometric measurements. We assessed the normality of differences between paired samples using the Shapiro-Wilk test and evaluated the significance of mean differences using paired t-tests and adjusted for multiple testing. We explored the relationship between the cephalometric measurements and height, head circumference and interpupillary distance. In this dataset of American whites with NF1, we confirmed in a modestly larger sample many of the findings found by Heerva et al. in an NF1 Finnish cohort. We found a shorter maxilla, mandible, cranial base, (especially anteriorly, p = 0.0001) and diminished facial height in adults, but not children, with NF1. Only one adult exhibited hypertelorism. The cephalometric differences in adults arise in part from cranial base shortening and thus result in a shorter face, mid-face hypoplasia, reduced facial projection, smaller jaw, and increased braincase globularity. In addition, we suggest that NF1 sphenoid bone shortening, a common event, is consistent with an intrinsic NF1 bone cell defect, which renders the bone more vulnerable to a random "second hit" in

    The cholesterol granuloma is well known in the middle ear, in the mastoid antrum and the air cells of temporal bone, mostly related to a chronic infectious process. There are other localizations such as the pleura, lung, pericardium, kidneys, arterial wall, nerves, brain, testicles, lymphatic ganglion and in the paranasals sinuses. Its localization in the mediofacial area is very unfrequent, having only been described 44 cases up to the year 2002. We present a 42 year-old patient, who required surgical treatment because of a increase in the volume of area her left facial of one month's old. It resulted to be secundary to an expansion of the maxilar sinus, such as seen on the computerized tomography carried out on the patient. The diagnosis was cholesterol granuloma, performed, through the anatomo-pathology study. We review the litterature on this subject and analyse the possible etiologic cause of this lesion, its clinic, diagnostic methodology and treatment.

    INTRODUCTION: The aim was to present a case report of a full-length extrusion of an obturator's core carrier into the maxillary sinus, causing clinical symptoms from the nose region with differential diagnostics aspects, which, in turn, led to several surgical treatments of the nostrils before...... diagnosis and correct endodontic retreatment of a maxillary right first molar. A 36-year-old man presented in 2012 with complaints from the right nostril region. Medical treatment with antibiotics and surgical procedures because of nasal stenosis resulted only in partial improvement. Five years earlier......, a root canal treatment was performed on the maxillary right first molar. Intraoral radiographs revealed 10-mm overfilling of root filling material into the maxillary sinus from the palatal root of tooth #3. METHODS: Before surgical removal of the excess root filling material, orthograde revision...

  18. Evolution of the Sinus Venosus from Fish to Human

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available The sinus venosus, the cardiac chamber upstream of the (right atrium, is a severely underinvestigated structure. Yet, its myocardium harbors the cardiac pacemaker in all vertebrates. In human, ectopic pacemaking and subsequent pathologies may originate from sinus venosus-derived myocardium surrounding the coronary sinus and the superior caval vein. In ectothermic vertebrates, i.e., fishes, amphibians and reptiles, the sinus venosus aids atrial filling by contracting prior to the atrium (atria. This is facilitated by the sinuatrial delay of approximately the same duration as the atrioventricular delay, which facilitates atrial filling of the ventricles. In mammals, the sinuatrial delay is lost, and the sinus venosus-derived myocardium persists as an extensive myocardial sheet surrounding the caval veins, which is activated in synchrony with the myocardium of the atria. The caval vein myocardium is hardly of significance in the healthy formed heart, but we suggest that the sinus venosus functions as a chamber during development when cardiac output, heart rate, blood pressure and architecture is much more like that of ectothermic vertebrates. The remodeling of the sinus venosus in mammals may be an adaptation associated with the high heart rates necessary for postnatal endothermy. If so, the endothermic birds should exhibit a similar remodeling as mammals, which remains to be investigated.

    Despite the importance of the morphology of the sinus of Valsalva in the behavior of heart valves and the proper irrigation of coronary arteries, the study of these sinuses from medical imaging is still limited to manual radii measurements. This paper aims to present an automatic method to measure the sinuses of Valsalva on medical images, more specifically on cine MRI and Xray CT. This paper introduces an enhanced method to automatically localize and extract each sinus of Valsalva edge and its relevant points. Compared to classical active contours, this new image approach enhances the edge extraction of the Sinus of Valsalva. Our process not only allows image segmentation but also a complex study of the considered region including morphological classification, metrological characterization, valve tracking and 2D modeling. The method was successfully used on single or multiplane cine MRI and aortic CT angiographies. The localization is robust and the proposed edge extractor is more efficient than the state-of-the-art methods (average success rate for MRI examinations=84% ± 24%, average success rate for CT examinations=89% ± 11%). Moreover, deduced measurements are close to manual ones. The software produces accurate measurements of the sinuses of Valsalva. The robustness and the reproducibility of results will help for a better understanding of sinus of Valsalva pathologies and constitutes a first step to the design of complex prostheses adapted to each patient.

    We demonstrate a novel nonintrusive technique based on tunable diode laser absorption spectroscopy to investigate human sinuses in vivo. The technique relies on the fact that free gases have spectral imprints that are about 10.000 times sharper than spectral structures of the surrounding tissue. Two gases are detected; molecular oxygen at 760 nm and water vapor at 935 nm. Light is launched fiber optically into the tissue in close proximity to the particular maxillary sinus under study. When investigating the frontal sinuses, the fiber is positioned onto the caudal part of the frontal bone. Multiply scattered light in both cases is detected externally by a handheld probe. Molecular oxygen is detected in the maxillary sinuses on 11 volunteers, of which one had constantly recurring sinus problems. Significant oxygen absorption imprint differences can be observed between different volunteers and also left-right asymmetries. Water vapor can also be detected, and by normalizing the oxygen signal on the water vapor signal, the sinus oxygen concentration can be assessed. Gas exchange between the sinuses and the nasal cavity is also successfully demonstrated by flushing nitrogen through the nostril. Advantages over current ventilation assessment methods using ionizing radiation are pointed out.

    Full Text Available Background. Thyroidectomy is one of the most frequently performed surgical procedures worldwide. Despite technical advances and high experience of thyroidectomy of specialized centers, it is still burdened by a significant rate of postoperative complications. Among them, the skin sinus formation is an extremely rare postthyroidectomy complication. Here, we first report the incidence of the skin sinus formation after thyroidectomy to identify the causes for skin sinus formation after thyroidectomy and to discuss its prevention and treatment options. Methods. A retrospective analysis was carried out of patients who underwent excision operation of fistula for postthyroidectomy skin sinus formation. Data were retrieved from medical records department of the Affiliated Hospital of Inner Mongolia Medical University. Results. Of the 5,686 patients who underwent thyroid surgery, only 5 patients (0.088% had developed skin sinus formation. All 5 patients successfully underwent complete excision of fistula. Conclusion. Infection, foreign body, thyroid surgery procedure, combined disease, and iatrogenic factors may be related with skin sinus formation after thyroidectomy. To reduce the recurrence of postoperative infections and sinus formation, intra- and postoperative compliance with aseptic processing, intraoperative use absorbable surgical suture/ligature, repeated irrigation and drainage, and postoperative administration of anti-inflammatory treatment are to be followed.

    The objective is to determine the appropriate duration of postoperative macrolide therapy for chronic rhinosinusitis to obtain a favourable outcome with endoscopic sinus surgery (ESS). The effectiveness of postoperative macrolide treatment was examined in patients with chronic rhinosinusitis who underwent ESS, by comparing 3-month (44 patients) and 6-month administration (66 patients) of clarithromycin (CAM) (200mg/day). Evaluation was made based on subjective symptoms and endoscopic findings at 3, 6 and 12 months after surgery. Seventeen (3-month CAM group) and 22 (6-month CAM group) subjects were able to be followed up to 12 months after surgery. No difference in effectiveness was observed between the groups until 6 months after surgery, but the 6-month treatment group showed significantly higher disappearance rates and significantly lower visual analogue scale (VAS) scores in the subjective symptoms of rhinorrhea and postnasal drip at 12 months after surgery. The positive finding rate of postnasal drip by endoscopic examination was also significantly lower in the 6-month treatment group at 12 months after surgery. These changes over time indicated gradual deterioration after discontinuation of CAM treatment in the 3-month treatment group, whereas a small improvement was observed after discontinuation in the 6-month treatment group. The results indicate that chronic sinusitis patients with rhinorrhea or postnasal drip should be treated with macrolides for 6 months after surgery in order to improve the long-term outcome of endoscopic sinus surgery.

A cutaneous sinus tract of odontogenic origin is a pathway through the alveolar bone that typically begins at the apex of an infected tooth or of an infected portion of the dental alveolus and empties infected material (pus through the skin. Where as the more common finding of an oral fistula is a pathway from the apical periodontal area of a tooth to the surface of the oral mucous membrane, permitting the discharge of suppurative material. Diagnosis, etiology and treatment are discussed with reference to patient history, clinical examinations, imaging, and treatment perspectives.Keywords: dental abscess, fistula, cutaneous sinus tract, odotogenic infection

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

  5. Oroantral communication as an osteotome sinus elevation complication.

    The sinus elevation procedure is a predictable technique to allow for placement of dental implants in the posterior maxilla when the height of the alveolar ridge is limited. The sinus elevation can be performed by various techniques. In the crestal approach, bone graft is utilized to hydraulically elevate the sinus membrane through an osteotomy prepared in the alveolar crest. The implant can be placed either immediately or at a later surgery. This is a case report of an oroantral communication that developed as a complication to a sinus elevation surgery performed with the crestal approach. A 54-year-old female patient presented for dental implant treatment. The patient reported sleep apnea and smoking. Full-thickness flap was reflected in the posterior maxilla and using trephines, an osteotomy was prepared, 1 mm short of the sinus. The trephined core of bone was pushed into the sinus using osteotomes. Particulate bone graft was introduced through the osteotomy to elevate the sinus membrane, and a collagen membrane was used over the bone graft. Six days after surgery, the patient returned to the clinic with an oroantral communication. The patient reported that she was using a positive-pressure breathing mask at night because of sleep apnea. A flap was extended to the tuberosity area and was rotated palatally to achieve closure. The use of the pressure breathing mask was discontinued. The oroantral communication was successfully closed. Relatively few complications have been reported using the osteotome sinus elevation technique. The use of a positive pressure mask may have complicated a sinus elevation surgery. Other factors that may have contributed to this complication include smoking and delayed healing of the area.

    Full Text Available A 41-year-old female with a history of uterine cancer and Celiac and Raynaud’s Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile. We present the first documented case of nitroglycerin sublingual therapy to successfully treat ophthalmic artery vasospasm following FESS. Nitroglycerin sublingual therapy is a promising treatment for ophthalmic vasospasm secondary to its ability to cross the blood-ocular barrier, its rapid onset of action, and its ability to promote relaxation of vascular smooth muscle.

    2015-01-01

    Chronic rhinosinusitis (CRS) is estimated to affect over 35 million people. However, not all patients with the diagnosis respond to standard medical and surgical treatments. Although there are a variety of reasons a patient may be refractory to therapy, one possible etiology is the presence of an underlying immunodeficiency. This review will focus on the description, recognition, and treatment of several antibody deficiencies associated with CRS, including common variable immunodeficiency (CVID), selective IgA deficiency, IgG subclass deficiency, and specific antibody deficiency (SAD). The diagnosis of antibody deficiency in patients with CRS is important because of the large clinical implications it can have on sinus disease management. CVID is treated with immunoglobulin replacement, whereas SAD may be managed symptomatically and sometimes with prophylactic antibiotics and/or immunoglobulin replacement.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Odontogenic cutaneous sinus tracts are often misdiagnosed, and they lead to facial wounds and scarring. Therefore, we must be aware of the possibility of this condition. A dental origin must be considered for chronic ulcers involving the cheek, chin and submental areas. The clinical course of this patient suggests two important clinical issues for prompt diagnosis. First, physical examination, including palpation and probing, are helpful for exploration of sinus tracts. Second, computed tomography is useful to detect the sinus tract and affected teeth. Computed tomography provides radiographic evidence of the relationship between the tooth and cutaneous region, and it may be superior to radiography.

    2016-09-01

    Full Text Available The dural venous sinus thrombosis is a benign disease, representing about 1% of cerebral vascular events. In some cases the development of the disease increased intracranial pressure or symptomatic epilepsy. The development towards a dural venous sinus thrombosis is rare, but is a condition to be considered before the development of ischemic vascular events and a history of recent head trauma. Intracranial hematomas or skull fractures can lead to the establishment of obstructive pathology of the dural venous sinuses. The knowledge of this entity is necessary for the critical care staff and neurosurgery staff.

    Full Text Available Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT and also cone beam computed tomography (CBCT are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported.

    Full Text Available Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It is very important to recognize the early signs of cavernous thrombosis. Treatment for septic cavernous sinus thrombosis is controversial but early use of empirical antibiotics is imperative.

    2004-07-01

    Purpose: To create a more effective method of demonstrating complex subject matter in ophthalmology with the use of high end, 3-D, computer aided animation and interactive multimedia technologies. Specifically, to explore the possibilities of demonstrating the complex nature of the neuroophthalmological basics of the human oculomotor system in a clear and non confusing way, and to demonstrate new forms of retinal surgery in a manner that makes the procedures easier to understand for other retinal surgeons. Methods and Materials: Using Reflektions 4.3, Monzoom Pro 4.5, Cinema 4D XL 5.03, Cinema 4D XL 8 Studio Bundle, Mediator 4.0, Mediator Pro 5.03, Fujitsu-Siemens Pentium III and IV, Gericom Webgine laptop, M.G.I. Video Wave 1.0 and 5, Micrografix Picture Publisher 6.0 and 8, Amorphium 1.0, and Blobs for Windows, we created 3-D animations showing the origin, insertion, course, main direction of pull, and auxiliary direction of pull of the six extra-ocular eye muscles. We created 3-D animations that (a) show the intra-cranial path of the relevant oculomotor cranial nerves and which muscles are supplied by them, (b) show which muscles are active in each of the ten lines of sight, (c) demonstrate the various malfunctions of oculomotor systems, as well as (d) show the surgical techniques and the challenges in radial optic neurotomies and subretinal surgeries. Most of the 3-D animations were integrated in interactive multimedia teaching programs. Their effectiveness was compared to conventional teaching methods in a comparative study performed at the University of Vienna. We also performed a survey to examine the response of students being taught with the interactive programs. We are currently in the process of placing most of the animations in an interactive web site in order to make them freely available to everyone who is interested. Results: Although learning how to use complex 3-D computer animation and multimedia authoring software can be very time consuming and frustrating, we found that once the programs are mastered they can be used to create 3-D animations that drastically improve the quality of medical demonstrations. The comparative study showed a significant advantage of using these technologies over conventional teaching methods. The feedback from medical students, doctors, and retinal surgeons was overwhelmingly positive. A strong interest was expressed to have more subjects and techniques demonstrated in this fashion. Conclusion: 3-D computer technologies should be used in the demonstration of all complex medical subjects. More effort and resources need to be given to the development of these technologies that can improve the understanding of medicine for students, doctors, and patients alike.

    Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT). Seventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement. Maxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology. Based on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.

    Idiopathic bronchiectasis is closely associated with chronic rhino-sinusitis. It can effectively control bronchiectasic symptoms to treat chronic rhino-sinusitis by FESS in the cases with bronchiectasis and chronic rhino-sinusitis. To explore the effect of functional endoscopic sinus surgery (FESS) on the treatment of bronchiectasis combined with chronic rhino-sinusitis. In this study, a total of 161 cases with bronchiectasis and chronic rhino-sinusitis were divided into medication group and operation group according to the therapeutic method for chronic rhino-sinusitis selected by them. For the treatment of chronic rhino-sinusitis, the cases in the operation group received FESS, but in the medication group cases took drugs alone. The score of clinical symptoms for bronchiectasis, forced expiratory volume in one second (FEV1), SNOT-22 score, and Lund-Mackay score were evaluated for all cases before and after treatment, respectively, and then the value changes in the score of clinical symptoms, FEV1, SNOT-22 score, and Lund-Mackay score between both time points were calculated. The frequency of acute exacerbation for bronchiectasis was also recorded within the 6-month follow-up. In this study, 58.9% of cases with bronchiectasis had chronic rhino-sinusitis. Follow-up lasted 6 months. Compared with pre-therapy, post-therapy score of clinical symptoms, SNOT-22 score, and Lund-Mackay score were all significantly decreased (all p therapy FEV1 failed to significantly improve (p > 0.05) in both groups. During the 6-month follow-up, the frequency of acute exacerbation was significantly less in the operation group than in the medication group (p therapy FEV1 between the two groups (p > 0.05).

    To evaluate the value of panoramic radiography in diagnosing maxillary sinus inflammation. A total of 214 maxillary sinuses from 114 panoramic radiographs were assessed in this study. Two independent experienced oral radiologists evaluated the images in random order for sinus inflammation. Using Cone beam CT images as the gold standard, the sensitivity and specificity of panoramic radiography were calculated, and inter- and intraobserver agreement for panoramic interpretation were obtained. The mean sensitivity and specificity of panoramic radiography were 81.0% and 85.6%, respectively. The weighted kappas for inter- and intraobserver agreement of panoramic radiography were 0.56 and 0.60, respectively. Panoramic radiography is a reasonably accurate method for diagnosing maxillary sinus inflammation and can be used for screening. However, additional examinations should be considered in patients with potentially significant pathology.

    2014-06-01

    Cavernous sinus syndrome is characterised by internal and external ophthalmoplegia and sensory deficits over the head due to combined deficits of the three cranial nerves (CNs) responsible for the eye movements and pupil function (CN III, IV, VI) and at least one branch of the trigeminal nerve (CN V). It has rarely been described in cats and may occur secondarily to inflammatory, infectious or neoplastic lesions within the region of the cavernous sinus on the ventral aspect of the calvarium. This report describes the clinical and magnetic resonance imaging findings in a 14-year-old domestic shorthair cat with neurological deficits compatible with cavernous sinus syndrome caused by presumptive extranodal lymphoma. Treatment with chemotherapy resulted in clinical and imaging remission. Identification of the neurological deficits in cavernous sinus syndrome allows accurate neuroanatomical localisation in order to target diagnostic imaging studies. © ISFM and AAFP 2013.

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

    Full Text Available Objective. The aim of our study was to try to determine the possible environmental risk factors for noninvasive fungal sinusitis in Egyptian patients. Methods. This is a prospective epidemiological case control study on the environmental risk factors of noninvasive fungal sinusitis. It included 60 patients and 100 age and sex matched controls. Results. There was a statistically significant relation between apartment floor, surface area, exposure to dust, exposure to cockroaches, poor air conditioning, and fungal sinusitis. Yet, no statistical significance was found between allergy related occupations, exposure to animals or plants, although their percentages were higher among cases, smoking, and urban or rural residence. Conclusion. We suggest that for patients with noninvasive fungal sinusitis a change in their living environment must be implied with better exposure to sunlight, larger well ventilated homes, proper cleaning of dust and cockroach extermination, and if possible the judicious use of air conditioners.

    Acute sinusitis is a common childhood illness. If it is overlooked or undertreated, suppurative and intracranial complications may develop. Amoxicillin has traditionally been the antibiotic of choice for treatment of acute sinusitis. However, the efficacy of amoxicillin has been reduced because of the emergence of bacteria producing b-lactamase and altered penicillin-binding proteins. This study compares the effectiveness of 10, 15, and 20 days of ceftibuten therapy with 14 days of erythromycin-sulfisoxazole therapy in treating acute sinusitis. The results indicate that both treatment regimens are effective in treating acute sinusitis (96% clinical response for erythromycin-sulfisoxazole vs 92% for a 10- or 15-day course of ceftibuten vs 100% for a 20-day course of ceftibuten). Longer treatment periods may be more effective in resolving the acute illness.

    Objective To design and assess the quality of a novel lateral retrocanthal endoscopic approach to the lateral cavernous sinus. Design Computer modeling software was used to optimize the geometry of the surgical pathway, which was confirmed on cadaver specimens. We calculated trajectories and surgically accessible areas to the middle fossa while applying a constraint on the amount of soft tissue retraction. Setting Virtual computer model to simulate the surgical approach and cadaver laboratory. Participants The authors. Main Outcome Measures Adequate surgical access to the lateral cavernous sinus and adjacent regions as determined by operations on the cadaver specimens. Additionally, geometric limitations were imposed as determined by the model so that retraction on soft tissue structures was maintained at a clinically safe distance. Results Our calculations revealed adequate access to the lateral cavernous sinus, Meckel cave, orbital apex, and middle fossa floor. Cadaveric testing revealed sufficient access to these areas using cavernous sinus. PMID:24498584

    We evaluated, by CFD simulation, effects of accessory ostium (AO) on maxillary sinus ventilation. A three-dimensional nasal model was constructed from an adult CT scan with two left maxillary AOs (sinus I) and one right AO (sinus II), then compared to an identical control model with all AOs sealed (sinuses III and IV). Transient simulations of quiet inspiration and expiration at 15 L/min, and nasal blow at 48 L/min, were calculated for both models using low-Reynolds-number turbulent analysis. At low flows, ventilation rates in sinuses with AOs (I ≈ 0.46 L/min, II ≈ 0.54 L/min), were both more than a magnitude higher than sinuses without AOs (II I ≈ 0.019 L/min, IV ≈ 0.020 L/min). Absence of AO almost completely prevented sinus ventilation. Increased ventilation of sinuses with AOs is complex. Under high flow conditions mimicking nose blowing, in sinuses II, III, and IV, the sinus flow rate increased. In contrast, the airflow direction through sinus I reversed between inspiration and expiration, while it remained almost constant throughout the respiration cycle in sinus II. CFD simulation demonstrated that AOs markedly increase maxillary sinus airflow rates and alter sinus air circulation patterns. Whether these airflow changes impact maxillary sinus physiology or pathophysiology is unknown. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available Background: Cerebral venous-sinus thrombosis is an uncommon form but important cause of stroke, especially in young-aged women. Methods: We performed a retrospective descriptive-analytical study in which 124 patients with cerebral venous-sinus thrombosis, who referred to Nemazee Hospital, Shiraz University of Medical Sciences from January 2000 to March 2008, were included, and their demographic, etiologic, radiological and prognostic characteristics were evaluated. Results: The patients' mean age was 34.01±10.25. Eighty seven (70.16% were women and 37 (29.83% were men. The most frequent clinical manifestations were headache, papilledema and seizures. Fifty seven (65.51% women took oral contraceptive pills. Twenty of 57 women (35.08% took the pill longer than one month to be able to fast in Ramadan or perform the Hajj ceremonies. In the mean time they developed cerebral venous-sinus thrombosis. Superior sagital sinus, with or without lateral sinuses, was the most involved area (70.96%. High mortality and morbidity rates (14.51% and 35.48%, respectively were found in patients. Poor prognostic factors at the time of admission were stupor and coma (P=0.001 and evidence of hemorrhage in primary CT scan (P=0.005. Conclusion: Taking oral contraceptive pills was a main factor associated with cerebral venous-sinus thrombosis. Clinical manifestations, prognostic factors, common involved sinuses and image findings of this study were similar to those of other studies. Health care policy makers should design a plan to warn susceptible women of the risk of cerebral venous-sinus thrombosis, and to educate them the ways to prevent it

    Nasal irrigation is widely used in treating sinonasal diseases. Not only does it remove static secretions and promote mucociliary clearance, but, in chronic rhinosinusitis, nasal flush is also a potential route for topical drug administration into paranasal sinuses. A clinical study was conducted to investigate how well nasal irrigation could reach paranasal sinuses with the ostiomeatal units blocked in chronic rhinosinusitis. This study was performed to (1) assess the ability of a nasal douche and spray to deliver a solution into the paranasal sinuses in chronic rhinosinusitis and (2) compare the performance of the two techniques. Fourteen patients, with bilateral chronic rhinosinusitis, underwent nasal irrigation with 140 mg/mL of iodinated contrast solution by 40 mL of douching using an irrigation syringe in one side, and 10 mL of spraying in the other side. A computed tomography scan was undertaken for each patient to determine the volume and the distribution of staining in the nose and paranasal sinuses. Only two patients had any staining, with a small amount present in a total of three maxillary sinuses (0.10 mL, 0.04 mL, and 0.13 mL). The mean volumes of paranasal sinus staining by nasal douche and nasal spray were 0.0093 and 0.01 mL, respectively. We found that the two techniques had a similar performance. Both of them delivered only a small amount of the solution, if any, into the sinuses (with a mean difference of -0.0007 mL; 95% CI, -0.02-0.02 mL; p = 0.94). Nasal douche and spray is not effective in delivering a nasal irrigation solution into paranasal sinuses in chronic rhinosinusitis.
