Sample records for ptosis nasal speech

  1. Speech nasality and nasometry in cleft lip and palate

    Directory of Open Access Journals (Sweden)

    Fabiane Rodrigues Larangeira

    Full Text Available ABSTRACT INTRODUCTION: Perceptual evaluation is considered the gold standard to evaluate speech nasality. Several procedures are used to collect and analyze perceptual data, which makes it susceptible to errors. Therefore, there has been an increasing desire to find methods that can improve the assessment. OBJECTIVE: To describe and compare the results of speech nasality obtained by assessments of live speech, the Test of Hypernasality (THYPER, assessments of audio recorded speech, and nasometry. METHODS: A retrospective study consisting of 331 patients with operated unilateral cleft lip and palate. Speech nasality was assessed by four methods of assessment: live perceptual judgement, THYPER, audio-recorded speech sample judgement by multiple judges, and nasometry. All data were collected from medical records of patients, with the exception of the speech sample recording assessment, which was carried out by multiple judges. RESULTS: The results showed that the highest percentages of absence of hypernasality were obtained from judgements performed live and from the THYPER, with equal results between them (79%. Lower percentages were obtained from the recordings by judges (66% and from nasometry (57%. CONCLUSION: The best results among the four speech nasality evaluation methods were obtained for the ones performed live (live nasality judgement by a speech pathologist and THYPER.

    Nasality is a very important characteristic of several languages, European Portuguese being one of them. This paper addresses the challenge of nasality detection in surface electromyography (EMG) based speech interfaces. We explore the existence of useful information about the velum movement and also assess if muscles deeper down in the face and neck region can be measured using surface electrodes, and the best electrode location to do so. The procedure we adopted uses Real-Time Magnetic Resonance Imaging (RT-MRI), collected from a set of speakers, providing a method to interpret EMG data. By ensuring compatible data recording conditions, and proper time alignment between the EMG and the RT-MRI data, we are able to accurately estimate the time when the velum moves and the type of movement when a nasal vowel occurs. The combination of these two sources revealed interesting and distinct characteristics in the EMG signal when a nasal vowel is uttered, which motivated a classification experiment. Overall results of this experiment provide evidence that it is possible to detect velum movement using sensors positioned below the ear, between mastoid process and the mandible, in the upper neck region. In a frame-based classification scenario, error rates as low as 32.5% for all speakers and 23.4% for the best speaker have been achieved, for nasal vowel detection. This outcome stands as an encouraging result, fostering the grounds for deeper exploration of the proposed approach as a promising route to the development of an EMG-based speech interface for languages with strong nasal characteristics.

    Aponeurotic defects and disinsertion of the levator aponeurosis are responsible for acquired involutional ptosis. The typical clinical findings in aponeurotic defects are high or moderate ptosis, good to excellent levator function, thinning of the eyelid above the tarsus, high to absent lid crease, and normal Müller's muscle function. The purpose of the treatment is to repair the defect or to advance the aponeurosis on the tarsus. This surgery can be done via the anterior approach with aponeurotic surgery or via the posterior approach with Müller's muscle conjunctival resection. In all cases, upper lid blepharoplasty is down.

    (1) To define normative nasalance data for Dutch language with "the NasalView System", and obtain a reference for normality when nasality is evaluated in children. (2) To investigate the minimal number of required speech tasks for a reliable nasalance measurement. 55 children (30 normal and 25 velopharyngeal insufficient), aged between 4 and 11 were included. All children had to read or repeat two Dutch passages ((one with a normal amount of nasal consonants (normal passage) and one with none (nonnasal passage)). Further, one normal and one velopharyngeal insufficient subject read a passage in repetition to test the NasalViews reproducibility: (1) For both passages, group means (GM) and standard deviations (S.D.) were used to compute "pathological nasalance boundaries" [GM +/- (2 x S.D.)], in combination with the coefficient of variation (CV), sensitivity, specificity and positive predictive values. (2) With ANOVA all sentences within each passage were tested for significant differences in nasalance. (1) The pathological boundaries were 28.6-41.4% (GM: 35.0) and 21.4-34.7% (GM: 28.1), for the normal and nonnasal passage, respectively. For the normal passage a sensitivity of 96%, a specificity of 93% and a positive predictive value of 92% was computed. For the nonnasal passage these parameters were 96, 95 and 96%, respectively. Intra subject CVs of 3.6% (normal subject) and 1.5% (VI subject) showed good reproducibility of measurements. (2) Within the normal passage only the third sentence was significantly different in nasalance, compared to the entire passage (31.2% versus 35.0%). Within the nonnasal passage the second and fifth sentences were significantly different (23.8 and 24.8% versus 28.1%). However, the individual nonsignificantly different sentences showed a higher variation in nasalance compared to the entire passages. The NasalView System seems to be reliable and quantifies valid nasalance values when nasality is evaluated. Within both passages high

    2007-01-01

    Previous research has found that "similar" sounds interact in phonological nasal consonant harmony, wherein certain consonants become nasals when the word contains a nasal (e.g., Kikongo: /-kun-idi/ [right arrow] [-kun-ini] "planted"). Across languages, stops and approximants are chiefly affected, especially voiced consonants and ones that match…

    The objective of the current study was to analyze the effects of rhinoseptoplasty on internal nasal dimensions and speech resonance of individuals with unilateral cleft lip and palate, estimated by acoustic rhinometry and nasometry, respectively. Twenty-one individuals (aged 15-46 years) with previously repaired unilateral cleft lip and palate were analyzed before (PRE), and 6 to 9 (POST1) and 12 to 18 months (POST2) after surgery. Acoustic rhinometry was used to measure the cross-sectional areas (CSAs) of segments corresponding to the nasal valve (CSA1), anterior portion (CSA2), and posterior portion (CSA3) of the lower turbinate, and the volumes at the nasal valve (V1) and turbinate (V2) regions at cleft and noncleft sides, before and after nasal decongestion with a topical vasoconstrictor. Nasometry was used to evaluate speech nasalance during the reading of a set of sentences containing nasal sounds and other devoid of nasal sounds. At the cleft side, before nasal decongestion, there was a significant increase (P nasalance values at PRE, POST1, and POST2 were not different from each other in both oral and nasal sentences. The measurement of CSAs and volumes by acoustic rhinometry revealed that rhinoseptoplasty provided, in most cases analyzed, a significant increase in nasal patency, without concomitant changes in speech resonance, as estimated by nasalance assessment.

    Velopharyngeal incompetence is known as a contributing factor to speech disorders. Suwaki et al. reported that nasal speaking valve (NSV) could improve dysarthria by regulating nasal emission utilising one-way valve. However, disease or condition which would be susceptible to treatment by NSV has not been clarified yet. This study aimed to evaluate the effect of NSV by questionnaire survey using ready-made NSV. Subjects were recruited through the internet bulletin, and NSV survey set was sent to the applicant. Sixty-six participants, who agreed to participate in this study, used NSV and mailed back the questionnaire which included self-evaluation and third-party evaluation of speech intelligibility. Statistical analysis revealed that the use of NSV resulted in significant speech intelligibility improvement in both self-evaluation and third-party evaluation (P effect of NSV on self-evaluation of speech intelligibility could be observed in cerebrovascular disease and neurodegenerative disease (P speech intelligibility by shutting up nostrils by fingers, and the significant effect of NSV on both self-evaluation and third-party evaluation of speech intelligibility was observed (P effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.

    2001-02-01

    The purpose of this study was to determine the effects of vowel height and vocal intensity on the magnitude of anticipatory nasal airflow in normal speakers when producing vowel-nasal-vowel (VNV) sequences. Measurements of nasal and oral airflow were obtained from 15 men and 12 women with normal speech during production of the VNV sequences /ini/ and /ana/ at low, medium, and high intensity levels. Ratios of nasal to oral-plus-nasal airflow were calculated for the initial vowel of both utterances at each of the intensity levels. Analysis of variance (ANOVA) procedures indicated a significant main effect of intensity level and a significant vowel-by-sex interaction effect (p vowel type. Female speakers exhibited greater airflow ratios during production of /ini/ than during productions of /ana/. Their airflow ratios were also greater during production of /ini/ than were those of male speakers. The results suggest that vocal intensity may affect velopharyngeal (VP) function in an assimilative nasal phonetic context. The results further suggest that anticipatory nasal airflow may be determined by the configuration of the oral cavity to a greater extent in women than in men. Theoretical and clinical implications are discussed.

    Voice low tone to high tone ratio (VLHR) is defined as the power ratio of a voice spectrum with a specific cut-off frequency. Previous studies have shown that there are significant correlations between VLHR and nasalance and hypernasality ratings in vowels. The correlation was investigated in this study using connected speech material. The Zoo Passage, the Rainbow Passage, the English Nasal Sentences, the Mandarin Nonnasal Sentences, and the Mandarin Nasal Sentences were used to acquire VLHRs, nasalance scores, and perceptual judgments of nasality. Each passage was recorded twice for averaging, and the cut-off frequencies from 200 Hz to 1200 Hz were used to survey for the presence of optimal correlations with VLHR. Participants : Ten native Mandarin speakers with an English learning history of over 8 years were enrolled. Main outcome measures : VLHRs, nasalance scores, and hypernasality ratings. The correlations of VLHR with nasalance (rho  =  .76, p connected speech show that these approaches have a potential value in terms of basic and clinical application.

    Full Text Available Desde hace varios años observamos un hecho que ocurre tras la infiltración grasa de la mama, y que es la ptosis o caída de la mama que tiene lugar 2 o 3 meses después de la intervención. Intentamos explicar este fenómeno por la ruptura y elongación de los ligamentos suspensorios de Cooper que tendrá consecuencias directas en los resultados. Este hecho produce una mayor ptosis en la mama madura, pero por el contrario supone un buen resultado en la mama tuberosa, ya que la ptosis provocada es la causa del relleno del polo inferior, principal problema de este tipo de mama. Consideramos en este artículo la técnica de lipoestructura mamaria y la elección del tipo de cánula a utilizar para la infiltración. Mostramos 2 ejemplos prácticos y un cuadro resumen de las indicaciones de la técnica. Tras años de experiencia en lipoestructura mamaria, pensamos que no es una técnica aplicable en todos los casos y que para obtener buenos resultados con ella es imprescindible elegir la mejor indicación para cada paciente.

    Science.gov (United States)

    Morax, S; Baudoin, F; Hurbli, T

    1995-12-01

    Post-traumatic ptosis may be classified as follows: ptosis occurring during lid avulsion, ptosis associated with fractures of the orbital roof and with foreign bodies, post-contusional ptosis, cicatricial ptosis, neurogenic ptosis and post-surgical ptosis. The patient must be thoroughly examined, including examination of the eye-ball, extra-ocular muscles, eyelid and evaluation of upper eyelid levator function and orbital and facial examination. The various surgical methods proposed include levator muscle surgery, aponeurotic surgery, Müller's muscle surgery and frontalis suspension surgery. Surgical indications and choice of surgical method essentially depend on the anatomo-clinical forms. The general rule is to operate under local anesthesia to obtain better control of the muscular function. Some cases are simple to treat such as post-contusional ptosis with good levator function which allows functional surgery with excellent static and dynamic results. Other relatively simple cases with non functional levators may only be treated on a static basis. Last but not least are more difficult cases in which levator function is difficult to evaluate pre-operatively because of severe fibrosis. The aim in such cases is to explore the eyelid by an anterior approach under local anesthesia and to propose either muscular surgery or a frontalis suspension according to the anatomical and functional status of the levator muscle.

    Sporadic inclusion body myositis is the most commonly acquired type of idiopathic inflammatory myopathy in people aged 50 and above. There is early weakness and atrophy of forearms and quadriceps and a third of patients also have mild facial weakness. Extraocular muscles are not affected and ptosis is rarely seen. The authors describe a unique case in which inclusion body myositis presented with early mid face weakness and atrophy resulting in unilateral lagophthalmus, and ptosis, which have not been documented before. This case is not only unique in its presentation but also emphasizes the importance of considering differential diagnoses and conservative measures before contemplating surgery.

    To evaluate the corneal topography and the topographic changes after ptosis surgery on patients affected by congenital and acquired blepharoptosis. Twenty eyes of 17 patients affected by acquired and congenital ptosis underwent surgical correction through anterior levator complex tightening. Computerized tomography (Syrius Sistem; CSO) was used to analyze any change in corneal astigmatism (CYL), simulated keratometry, anterior corneal symmetry index front, apical keratometry front, and central corneal thickness. Visual acuity, margin reflex distance, and levator function were also measured. After surgical ptosis repair, corneal topography demonstrated a reduction in average keratometry of 0.15 ± 0.47 diopters (D) and in corneal astigmatism of 0.26 ± 1.12 D. Significant differences were found in apical keratometry front (-1.84 ± 1.76 D) and in best-corrected visual acuity (-0.18 ± 0.06 logMAR) in the postoperative examinations. Central corneal thickness did not show significant differences between preoperative and postoperative examinations. Postoperative topographic maps showed a reduction of symmetry index front (0.10 ± 0.64 D). Eyelid ptosis modifies anterior corneal surface inducing refractive errors and modifying corneal astigmatism in patients, thus affecting the quality of vision. The surgical correction of blepharoptosis induces anterior corneal surface modification, restoring corneal symmetry and regular corneal astigmatism. Postoperative corneal topography showed normal corneal contours.

    Congenital ptosis is a rare condition characterized by lower positioning of the upper eyelid that is present at birth and is a clinical condition that is persistent if not treated. It may be unilateral or bilateral and may be associated with other ocular disorders or systemic conditions, including Marcus Gunn, Horner, and Duane syndromes. It is a benign condition but causes functional, cosmetic, and psychological problems in children. However, not all patients need to undergo surgery, and usually only patients at risk of amblyopia need a prompt surgical correction, while in other cases, surgery can be postponed. The grade of ptosis, the eyelid function, and the amblyopic risk are the parameters that affect the ophthalmologist’s decision on timing of surgery and the surgical technique to be used. In fact, there are several types of surgical techniques to correct a congenital ptosis, although very often more than one is needed to obtain an acceptable result. This paper reviews the causes of congenital ptosis and associated diseases. Particular emphasis is given to surgical management and different procedures available to correct the upper eyelid anomaly and avoid permanent damage to visual function. PMID:28280295

    Institute of Scientific and Technical Information of China (English)

    李国俊; 杨军

    2011-01-01

    In the continuous flow of speech in Mandarin, it is generally accepted that the coda of -n is easily changed into the coda of -m because the liaison is affected by post-labial consonants: b, p, m in the assimilation of nasal codas. In fact, the codas in the syllables of alveolar nasal compound vowels in the speech flow are unstable. By this instability and the impact of co-articulation, the nasal Codas tend to appear reverse assimilation before a plosive, nasal coda losing before the fricative consonants and vowels, and nasal coda losing when a nasal syllable happens in a sentence or a sententiallike sentence. This paper aims to verify by the experiments to show that the nasal codas tend to appear reverse assimilation before a plosive and nasal coda losing when a nasal syllable happens in a sentence or a sentential-like sentence.%在普通话的连续语流中,鼻韵尾的同化现象得到普遍认可的是,在日常口语中,因连读时受后唇音声母b,p、m的影响,-n韵尾容易变成-m韵尾.事实上,前鼻音音节的韵尾在语流中是不稳定的,受这种不稳定状态及协同发音的影响,韵尾容易出现塞音前的逆同化现象,也容易出现连读时在擦音和零声母前的脱落,以及前鼻音音节处于句末或类句末①的脱落情况.本文在前人的基础上,通过实验验证语流中前鼻音节韵尾容易出现塞音前的逆同化及句末或类句末的脱落现象.

    Hutters, B; Brøndsted, K

    1992-01-01

    There is a need for clinical methods which give more direct information about the behaviour of the velopharyngeal mechanism in natural speech than do the examination methods normally applied to patients suffering from velopharyngeal insufficiency. One possibility is the recording of nasal airflow in order to detect nasal emission of air. The purpose of the present study is to examine the qualities and the characteristics of a simple and cheap nasal anemometer. As this type of flowmeter is considered less reliable than most other flowmeters, its limitations must be clearly understood and accounted for in drawing conclusions. Therefore, nasal airflow in speech obtained with this flowmeter is discussed in relation to nasal airflow obtained by the more reliable pneumotachograph and in relation to nasal airflow data found in the literature. The tests made here suggest that, at least for the type of speech material and measurements used in the present study, reliable nasal airflow data can be obtained by the anemometer.

    2015-01-01

    To compare axial globe length between affected and unaffected sides in patients with unilateral congenital ptosis. This prospective observational study included 37 patients (age range: 7 months to 58 years). The axial globe length, margin reflex distance-1 (MRD-1), and refractive power were measured. The axial globe length difference was calculated by subtracting the axial globe length on the unaffected side from that of the affected side. The relationships among axial globe length differences, MRD-1 on the affected sides, and patient ages were analyzed using multiple regression analysis. No significant differences were found in the axial globe length between sides (P = .677). The axial globe length difference was 0.17 ± 0.30 mm (mean ± standard deviation), and two patients (5.4%), aged 32 to 57 years, showed axial globe length more than 0.67 mm longer (corresponding to a refractive power of 2 diopters) on the affected side compared to the unaffected side. The multiple regression model between axial globe length difference, patient age, and MRD-1 on the affected sides was less appropriate (YAGL = 0.003XAGE-0.048XMRD-1 +0.112; r = 0.338; adjusted r2 = 0.062; P = .127). The cylindrical power was greater on the affected side (P = .046), although the spherical power was not different between sides (P = .657). No significant difference was identified in the axial globe length between sides, and only 5% of non-pediatric patients showed an axial globe length more than 0.67 mm longer on the affected side. Congenital ptosis may have little effect on axial globe length elongation, and the risk of axial myopia-induced anisometropic amblyopia may be low in patients with unilateral congenital ptosis.

    In patients with a repaired cleft palate, nasality is typically diagnosed by speech language pathologists. In addition, there are various instruments to objectively diagnose nasalance. To explore the potential of nasalance measurements after cleft palate repair by NasalView(®), we correlated perceptual nasality and instrumentally measured nasalance of eight speech items and determined the relationship between sensitivity and specificity of the nasalance measures by receiver-operating characteristics (ROC) analyses and AUC (area under the curve) computation for each single test item and specific item groups. We recruited patients with a primarily repaired cleft palate receiving speech therapy during follow-up. During a single day visit, perceptive and instrumental assessments were obtained in 36 patients and analyzed. The individual perceptual nasality was assigned to one of four categories; the corresponding instrumental nasalance measures for the eight specific speech items were expressed on a metric scale (1-100). With reference to the perceptual diagnoses, we observed 3 nasal and one oral test item with high sensitivity. However, the specificity of the nasality indicating measures was rather low. The four best speech items with the highest sensitivity provided scores ranging from 96.43 to 100%, while the averaged sensitivity of all eight items was below 90%. We conclude that perceptive evaluation of nasality remains state of the art. For clinical follow-up, instrumental nasalance assessment can objectively document subtle changes by analysis of four speech items only. Further studies are warranted to determine the applicability of instrumental nasalance measures in the clinical routine, using discriminative items only.

    A noncosmetic blepharoplasty with levator tuck was planned to repair a congenital ptosis presumed to be caused by levator maldevelopment. During surgery a mass was found in the lid, revealing the ptosis to be mechanical in nature. Biopsy and subsequent pathological exam revealed this to be a plexiform neurofibroma in a reportedly undiagnosed patient.

    This report describes the rare case of a 27-year-old female patient with conversion disorder who presented unilateral ptosis with ipsilateral muscle spasm of orbicular oculi. The co-existing of ptosis and muscle spasm of orbicular oculi indicates that, in accord with prior reports, the overactivity of orbicular oculi is essential in psychogenic pseudoptosis. The co-existing of unilateral ptosis and ipsilateral muscle spasm of orbicular oculi in the present case leads us to the conclusion that the overactivity of orbicular oculi is essential in psychogenic pseudoptosis.

    2012-02-01

    Full Text Available Abstract Introduction The application of lidocaine to the nasal mucosal area corresponding to the sphenopalatine fossa has been shown to be effective at extinguishing pain attacks in patients with a cluster headache. In this report, the effectiveness of local administration of lidocaine on cluster headache attacks as a symptomatic treatment of this disorder is discussed. Cases presentation A 22-year-old Turkish man presented with a five-year history of severe, repeated, unilateral periorbital pain and headache, diagnosed as a typical cluster headache. He suffered from rhinorrhea, lacrimation and ptosis during headaches. He had tried several unsuccessful daily medications. We applied a cotton tip with lidocaine hydrochloride into his left nostril for 10 minutes. The ptosis responded to the treatment and the intensity of his headache decreased. Conclusion Intranasal lidocaine is a useful treatment for the acute management of a cluster headache. Intranasal lidocaine blocks the neural transmission of the sphenopalatine ganglion, which contributes to the trigeminal nerve as well as containing both parasympathetic and sympathetic fibers.

    Hypothyroidism can cause a variety of signs and symptoms of the neuromuscular system. However, ptosis in a patient with hypothyroidism is very rare. We report here on a case of central hypothyroidism that was due to Sheehan's syndrome and it manifested as bilateral ptosis in a 51-yr-old woman. She complained of exertional dyspnea and weakness. About 25-yr ago, she had a history of severe postpartum vaginal bleeding. The laboratory studies demonstrated hypopituitarism with secondary hypothyroidism. The ptosis was improved by replacement of thyroid hormone. Hypothyroidism should be considered in the differential diagnosis of patients who manifest with ptosis and that prompt replacement of hormone can lead to a complete recovery.

    Patients with gland hyperplasia as well as thickening and redundancy of nasal skin who receive treatment that addresses only the support structures generally suffer from lack of definition of the nasal tip. We report on a case in which this problem was treated by redefinition of the nasal dorsum and tip through resection of the redundant skin. The surgical approach involved open rhinoplasty with a columella-alar incision, wide dissection of the dorsum filling, caudal traction, and resection of excess tissue. This method enabled reshaping of the nasal dorsum and tip by readjustment of the cutaneous covering of the osteocartilaginous structures.

    Full Text Available An upper lid eccrine hidrocystoma presenting as early childhood progressive ptosis is very rare. We present a 9-year-old female child with droopy right upper lid since birth and progressive increase in symptoms. She had right upper lid ptosis (marginal reflex distance 1 of −1 mm with fair levator function (8 mm and abnormal cystic change on the conjunctival side. Computerized tomography imaging delineated the well-defined cystic lesion with homogeneous cavity with no contrast enhancement. Following the cyst excision, a giant eccrine hidrocystoma measuring 25 mm × 15 mm was removed, the largest reported in pediatric eyes. The case demonstrates the possibility of giant lid eccrine hidrocystomas presenting as progressive ptosis at a pediatric age and the need for early surgical intervention to prevent amblyopia.

    Twenty cases of severe progressive ophthalmoplegia (Myopathic ptosis) with significant ptosis were treated by various procedures, including levator resection with blepharoplasty or frontalis suspension using temporalis fascia. Surgical indications were generally limited to cases with poor or absent levator function. The results are analysed after an average follow-up of 6 months. The particular problems concerning surgery of myopathic ptosis are discussed.

    Because of the great variety of congenital ptosis and surgical procedures, the choice of a definite surgical protocol is rather difficult. The author reports here three surgical techniques which have been used for over 5 years. The levator muscle resection with upper lid fold reconstruction via a skin approach is still the preferred technique in most cases. The main problem is to determine the magnitude of muscle resection which is directly related to the levator function. Frontalis suspension with autogenous fascia-lata or synthetic materials as Goretex is performed in case of levator resection failure: non-functioning muscle, muscular dysfunction as in the Marcus Gunn syndrome. The conjunctiva-Müller's muscle excision avoiding overcorrection is indicated in cases of minor congenital ptosis with good muscular function and positive response to topical 10% epinephrine drops.

    2013-12-01

    Full Text Available Nasality is the common problem in subjects with repaired / unrepaired cleft palate, which affects the speech intelligibility. Nasal resonance is not only seen in disordered speech, even normal speech also consist some amount of nasality. Example: Among the Indian languages, Malayalam has got more nasal resonance than any other languages. Nasality can be assessed by subjective as well as objective methods. Perceptual judgment of nasality is done using various rating scales. These rating scales have used different rating points ranging from five point scale to nine point scales. The judges for these rating scales were from trained speech pathologists to clients themselves. Since this is a subjective task, standard data / normative data cannot be established due to many disadvantages associated with this method. Hence, standard objective methods are essential to assess the velopharyngeal dysfunction and to provide guidelines for suitable rehabilitation method.

    The purpose of this study was to determine whether there are dialectal and gender related differences in nasalance of main Mandarin vowels and three sentences in 400 Chinese normal adults. The mean nasalance score difference for dialect and gender was significant (p nasalance scores show that Chongqing > Beijing > Shanghai > Guangzhou for the nasal sentence, oro-nasal sentence, /a/, /i/ and /u/. In addition, the average nasalance scores of females were higher than those of males for all speech materials in all dialects. The clinical significance of this study can be helpful in making nasalance clinical decisions for Chinese people with cleft palate, hearing disorders and dysarthria with resonance disorders. It also shows the theoretical and socio-cultural features for linguists considering dialects and gender.

    In patients with cleft lip and palate (CLP), the assessment of velopharyngeal morphology and function and the quantitative analysis of perceptual consequences of velopharyngeal insufficiency are of major importance regarding the effective planning of velopharyngoplasties for speech improvement. The NasalView, a new instrument for the objective assessment of rhinophonia, is presented. The NasalView measures nasalance, the relative sound pressure level of the nasal signal in speech, expressed as a percentage. In order to evaluate the effectiveness of the computerised measurement of nasalance, 156 patients with surgically treated CLP were examined. The NasalView differentiated with high sensitivity and specificity between patients with normal nasal resonance and patients with varying degrees of hypernasality. To illustrate the importance of the NasalView for making the decision for a velopharyngoplasty, a single case is presented.

    2011-12-01

    Full Text Available The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI is an alternative treatment for patients with conditions that preclude surgery and for those individuals with a hypofunctional velopharynx (HV with a poor prognosis for the surgical repair of VPI. Understanding the role and measuring the outcome of prosthetic treatment of velopharyngeal dysfunction requires the use of tools that allow for documenting pre- and post-treatment outcomes. Experimental openings in speech bulbs have been used for simulating VPI in studies documenting changes in aerodynamic, acoustic and kinematics aspects of speech associated with the use of palatal prosthetic devices. The use of nasometry to document changes in speech associated with experimental openings in speech bulbs, however, has not been described in the literature. Objective: This single-subject study investigated nasalance and nasality at the presence of experimental openings drilled through the speech bulb of a patient with HV. Material and Methods: Nasometric recordings of the word "pato" were obtained under 4 velopharyngeal conditions: no-opening (control condition, no speech bulb, speech bulb with a 20 mm² opening, and speech bulb with 30 mm² opening. Five speech-language pathologists performed auditory-perceptual ratings while the subject read an oral passage under all conditions. Results: Kruskal-Wallis test showed significant difference among conditions (p=0.0002, with Scheffé post hoc test indicating difference from the no-opening condition. Conclusion: The changes in nasalance observed after drilling holes of known sizes in a speech bulb suggest that nasometry reflect changes in transfer of sound energy related to different sizes of velopharyngeal opening.

    A set of 7 word tests with different number of nasal phonemes was prepared. These tests are adjusted to technical possibilities of nasal resonance examination by means of own construction apparatus. The VII-th test consisting only oral speech sounds appeared to be most important for estimating physiological nasal resonance characteristic for the Polish language and gave individual timbre of the voice. For Polish language these resonance rate is 15.2%. It is useful as reference data to evaluate patients with pathological nasal resonance. The VII-th test together with the V-th one which contain 6.3% of nasal consonants, and the VI-th with 33.3% of them were used for detailed evaluation of nasal resonance.

    The purpose of this study was to evaluate nasalance measures in German-speaking patients with different types of repaired cleft lip and palate and to find out if significant nasalance gender differences exist in the different cleft groups. A total of 125 German-speaking cleft patients (74 male and 51 female) were included in this study: 18 patients with isolated unilateral cleft lip (UCL; mean age: 13.00 +/- 2.03 years), 66 patients with complete unilateral cleft lip and palate (UCLP; mean age: 14.80 +/- 3.45 years), 25 patients with isolated cleft palate (CP; mean age: 14.60 +/- 3.48 years), and 16 patients with complete bilateral cleft lip and palate (BCLP; mean age: 14.30 +/- 3.61 years). Nasalance data were collected and computed using the NasalView hardware/software system (Fa. Tiger Electronics, Seattle, WA). Speech stimuli according to a modified Heidelberg Rhinophonia Assessment Form (sustained vowels "a," "e," "i," "o," and "u"; oral and nasal sentences; and three oral-nasal reading passages) were used to obtain nasalance scores. Nasalance distance and ratio were also calculated for the oral and nasal sentences and for one of the oral-nasal reading passages. Unpaired t tests showed no significant gender nasalance differences in each cleft group. Analysis of variance showed no significant differences in mean nasalance distance and ratio. For the nasal sentence, a significant difference (P = 0.032) in mean nasalance scores was found between the UCL and UCLP groups.

    To evaluate the safety and efficacy of the protective ptosis created by botulinum neurotoxin type-A in lagophthalmos cases due to peripheral facial paralysis. Protective ptosis was induced by 7.5 U botulinum neurotoxin type-A injection into levator muscles in 15 patients with peripheral facial paralysis and lagophthalmos. Its efficacy and safety were evaluated prospectively. Complete ophthalmological examinations were performed before and after injections; interpalpebral fissure, upper eyelid margin reflex distance, and levator muscle function were measured. In control visits, degree and duration of ptosis and side effects of the drug were evaluated. The mean age of the patients was 55 ± 14.28 years (22-78 years). Ptosis created by botulinum neurotoxin type-A injection was severe in 12 patients (80%), moderate in 2 patients (13.3%), and mild in 1 patient (6.7%). The effect of botulinum neurotoxin type-A began in 2.33 ± 1.44 days and peaked in 5.73 ± 2.63 days. No patient needed a second injection. The mean duration for ptosis was 10.53 ± 2.89 weeks. After development of ptosis, statistically significant improvement in corneal symptoms (p lagophthalmos, protective ptosis created by botulinum neurotoxin type-A injection into the levator muscle is a reliable and effective technique for the protection of the ocular surface and treatment of existing corneal complications. It represents an alternative treatment modality in cases requiring surgery.

A 36-year-old nurse was referred to our eye clinic with unilateral mydriasis and ptosis in the right eye 3 days after botulinum toxin injection for a cosmetic procedure. Botulinum toxin was applied to her eye by a doctor at her hospital who was not an ophthalmologist. She was treated with topical apraclonidine 0.5% ophthalmic solution. Her ptosis decreased to 2 mm with apraclonidine and her visual axis improved. Mydriasis was present for 3 weeks and then disappeared. Mild ptosis continued for 3 months, then resolved completely. Patients seeking treatment with botulinum toxin A for cosmetic purposes should be warned about the possibility of ptosis and mydriasis after injection. If these side effects are seen, the patient must be referred to an ophthalmologist for appropriate management. Keywords: botulinum toxin, mydriasis, ptosis

    Full Text Available One of the first signs of facial ageing appears in the forehead, with the descent of the lateral part of the brow. This is a troubling condition for all patients and elevation of the lateral part of the brow becomes a more and more frequent demand. The authors present their experience in 350 consecutive cases of direct eyebrow lift ("butterfly wing" incision alone or in combination with rhytidectomy and/or blepharoplasty. The majority of the patients were female (90%. The age ranged from 43 to 85 years. Eighty per cent of the cases were performed simultaneously with rhytidectomy and blepharoplasty, 16% were performed in association with blepharoplasty and eyebrow lift alone represented 4%. The most common complication was epidermal cyst (3.4% and suture dehiscence (2%. The "butterfly wing" incision provides a useful alternative to correction of eyebrow ptosis. Indication for surgery is dependent more on the ageing signs than on the patient′s chronological age. The final results are consistently very gratifying to the patient and to the plastic surgeon alike.

    Full Text Available The Goldilocks mastectomy is a method that uses redundant mastectomy flap tissue alone to create a breast mound in female American patients with macromastia. Goldilocks mastectomy was performed for obese Japanese females with breast ptosis, and its indications were considered for Japanese female patients. This report presents the results of five patients who underwent Goldilocks mastectomy, including one with bilateral breast cancer. The average age of the patients was 72 years (range: 67–76 years. The body mass index (BMI was more than 25 in all the cases. Four patients had invasive ductal carcinoma, and one patient had noninvasive ductal carcinoma of bilateral breasts. The cosmetic results were found to be good in two cases [a patient with bilateral breast cancer and a severely obese patient (BMI = 39]. The cosmetic results in the other three cases were poor. Although the reconstructed breast size was small, this procedure resulted in better cosmetic results than what would be achieved with the usual method of mastectomy for Japanese patients with bilateral breast cancer and severely obese Japanese patients.

    Full Text Available Context: Velopharyngeal dysfunction (VPD is one of the associated condition reported in individuals with repaired cleft lip and palate (RCLP leading to hypernasality. Nasality can be assessed by nasometer through nasalance values. But, mean nasalance values (N found to be overlapping between individuals with RCLP and normals. To overcome these limitations Nasalance Distance (ND and Nasalance Ratio (NR are derived based on nasalance range. Aims: The study is aimed to evaluate, correlate and compare acoustical (N, ND & NR and perceptual measures of nasality between the children with RCLP and control group. Settings and Design: Institutional setup and standard group comparison design Methods and Material: The study included fifteen children with RCLP ranging from 6 to 11 years and the control group consists of age and gender matched 15 typically developing children. Four point standard rating scale was used to rate the hypernasality by three speech language pathologists (SLP’s and Nasometer was used to measure the mean and derived nasalance scores for vowels and sentences in Kannada. Statistical analysis: SPSS, Cronbach’s Alpha test, multivariate analysis and Pearson’s product movement correlation were used to analyze the data. Results: Significant increase in the mean nasalance value and NR was seen in children with RCLP than the control group, whereas ND was contrary. ND was highly correlated with perceived nasality than N. The NR of sentences shows high negative correlation. Conclusions: The measures based on range of nasalance can be adapted to the routine clinical examinations for better correlation with perceived nasality.

    Previous studies have found that the velum in speech production may not only serve as a binary switch with on-off states for nasal and non-nasal sounds, but also partially alter the acoustic characteristics of non-nasalized sounds. The present study investigated the unique functions of the velum in the production of non-nasalized sounds by using morphological, mechanical, and acoustical measurements. Magnetic resonance imaging movies obtained from three Japanese speakers were used to measure the behaviors of the velum and dynamic changes in the pseudo-volume of the pharyngeal cavity during utterances of voiced stops and vowels. The measurements revealed no significant enlargements in the supraglottal cavity as subjects uttered voiced stops. It is found that the velum thickness varied across utterances in a way that depended on vowels, but not on consonants. The mechanical and acoustical observations in the study suggested that the velum is actively controlled to augment the voice bars of voiced stops, and nostril-radiated sound is one of the most important sources for voice bars, just as is laryngeal wall vibration. This study also proposed a two-layer diaphragm model that simulates transvelar coupling during the production of non-nasalized speech sounds. The simulation demonstrated that the model accurately represented the basic velar functions involved in speech production.

    Twenty seven frontalis sling procedures were performed with use of autogenous fascia-lata. The choice of this procedure was performed sometimes at the first stage for severe ptosis with poor levator function: isolated congenital ptosis, blepharophimosis syndrome, Marcus Gunn Jaw-Winking ptosis, ptosis with severe myopathy, some traumatic ptosis. This procedure was also performed in a second stage after failure of the useful procedures (levator resection) and after verification that the levator was not exploitable. Sometimes the choice of the procedure is done during the exploration of the eyelid and the levator because there is not always "parallelism" between the levator function and his anatomy. So operative technique must always be performed by a complete anterior palpebral approach, the surgeon can passed the suspensory material from the tarsus to the roof of the orbit, just anterior to the levator aponeurosis, and then out above the eyebrow. The pulley this created by the periosteum of the superior orbital margin prevents vertical traction lines. The skin crease is created with sutures which pick up the tarsus and the lid retractors. If, during the explorations the levator is "exploitable", a super maximum levator resection will be performed at the first stage, the frontalis suspension will be maintained in case of failure of the levator resection.

    Blepharophimosis-ptosis-epicanthus inversus syndrome (OMIM #U10100) is a rare autosomal-dominant disorder in which an eyelid malformation is associated (type I) or not (type H) with premature ovarian failure in the affected female. It is invariably characterized by 4 major features: (1) bilaterally shortened horizontal palpebral fissure (blepharophimosis); (2) severe impairment of the superior palpebral levator (ptosis); (3) a vertical skin fold arising from the lower eyelid, which inserts medially in the upper lid (epicanthus inversus) and (4) an increased inner can-thal distance with a normal outer canthal distance (telecanthus). The mutations causing this disorder are found in the FOXL2 gene, a forkhead transcription factor, located in 3q23. Although many patients with blepharophimosis-ptosis-epicanthus inversus syndrome have an affected parent, a conspicuous number of sporadic cases also have been reported. We describe here a sporadic case with a mutation in the FOXL2 gene that was well characterized both clinically and molecularly.

    To determine the age at onset of amblyopia, the response to occlusion therapy, and the association with systemic disorders in children with congenital eyelid ptosis. Retrospective chart review of children seen at Seattle Children's Hospital with moderate or severe congenital ptosis. Assessments were longitudinal visual acuity development using objective methods, definition of ptosis severity by eyelid margin to pupillary light reflex distance (margin reflex distance [MRD]), age at amblyopia diagnosis, correlation between amblyopia and MRD, and associated systemic disorders. Eighty-four children with moderate-to-severe congenital ptosis met inclusion criteria; the mean longitudinal follow-up was 49.1 months. Fifteen (18%) of these children had amblyopia, of which 9 had deprivation amblyopia (mean age 17.3 months ± 11.2) and 6 had anisometropic or strabismic amblyopia (mean age 60 months ± 11.8). Eleven (73%) of the children with amblyopia were successfully treated with occlusion therapy. Amblyopia was not correlated with MRD. A systemic disorder was identified in 29 (35%) of the children, the most common being genetic, chromosomal, or neurologic conditions. Patients with systemic disorders and developmental delay have significantly lower visual acuity bilaterally compared with patients without systemic disorders (P ≤ .003). Using longitudinal and objective visual acuity assessments, the incidence of amblyopia was 18% in children with moderate to severe congenital ptosis. Visual deprivation was the predominant risk factor that was reliably distinguished by its earlier onset in young children. The best indicator of amblyopia in children is visual acuity rather than MRD measurements. Systemic disorders are frequent in children with moderate to severe congenital ptosis.

    2011-01-01

    Purpose To test the hypothesis that posterior approach ptosis surgery, with or without blepharoplasty, can improve the cosmetic appearance of the eyelid. Methods In a retrospective, observational, consecutive case cohort study, 261 patients who had posterior approach upper eyelid ptosis surgery with or without concurrent blepharoplasty performed by one surgeon, between 1997 and 2009, were reviewed. Patients were included if they had symmetric eyelid position within 1.5 mm at 3 months after surgery. Outcome measures were subjective grading of eyelid margin contour, millimeters of tarsal platform show (TPS), and millimeters of eyebrow fat span (BFS). Paired preoperative and postoperative standardized photographs were viewed in masked fashion by three experts. Results One hundred and forty patients (55 men, 85 women, mean age 70 years, range 20–93) who underwent 233 posterior approach procedures for correction of upper eyelid ptosis had postoperative eyelid symmetry within 1.5 mm. Concurrent blepharoplasty was performed in 67 cases. Eyelid contour scores were significantly improved following surgery (P=.009). Ptosis surgery, without blepharoplasty, decreased the TPS, from 6.1±2.5 mm to 4.8±2.0 mm (P<.001). Patients who underwent concurrent blepharoplasty had a statistically insignificant increase of TPS from 4.0±3.5 mm to 4.3±3.6 mm, had a decrease of BFS from 20.8±6.3 mm to 17.7±6.4 mm (P=.001), and showed similar BFS symmetry postoperatively, compared to patients who had ptosis surgery only. Conclusions Posterior approach surgery alone was often successful in controlling TPS: it shortened the TPS. Blepharoplasty combined with posterior approach ptosis surgery tended to lengthen the TPS and shorten the BFS. PMID:22253486

    A case of an 87-year-old woman with a history of Graves disease presenting with a 5-year history of severe ptosis and very poor levator function of the left side is presented. MRI revealed marked enlargement of all extraocular muscles and significant enlargement of the left levator muscle. Given the patient's age and atypical presentation of thyroid eye disease (TED), she was taken to the operating room for biopsy and ptosis repair with frontalis suspension. Histopathological analysis revealed chronic inflammation and fibrosis consistent with Graves disease.

    Vincristine is used in the treatment of leukemias, solid tumors, and lymphomas. A case of a 2-year-old boy undergoing treatment for leukemia who developed sudden onset bilateral ptosis and ophthalmoplegia along with generalized neuropathy due to vincristine's neurotoxic effects is presented. He was successfully treated with pyridoxine and pyridostigmine. The possible mechanisms of action and the treatment for vincristine-induced neuropathy are discussed. Prompt treatment and close follow-up is needed, especially in children because prolonged ptosis and motility restriction may have a profound effect on a child's visual function.

    Full Text Available Anterior nasal spine fractures are a quite rare type of nasal bone fractures. Associated cervical spine injuries are more dangerous than the nasal bone fracture. A case of the anterior nasal spine fracture, in a 18-year-old male was presented. Fracture of the anterior nasal spine, should be considered in the differential diagnosis of the midface injuries and also accompanying cervical spine injury should not be ignored.

    Objective : To compare nasal ram pressure (NRP) data with perceptual speech assessments in young children following palatoplasty. Design and Setting : NRP monitoring, a noninvasive technique using a two-pronged nasal cannula that detects nasal airflow during speech, was performed on patients 12 months following palatoplasty in our Craniofacial Center. Patients : Eighteen English-speaking nonsyndromic patients, aged 21 to 28 months, without hearing or language deficits, underwent NRP testing. Main Outcome Measured : During NRP measurement, the number of oral stop consonants produced spontaneously or following prompts was recorded. Stops were considered produced with velopharyngeal closure if NRP demonstrated no nasal airflow. The percentage of closed stops as measured by NRP was compared to the clinical assessment by craniofacial team speech-language pathologists. Results : Eight patients achieved 100% stop closure. Four patients obtained 90% to 96% stop closure. Three patients had stop closure of 85%, 78%, and 50%. Three patients had 0% stop closure; two of these patients subsequently underwent secondary palatal surgery. No significant clinical speech deficits were noted in patients with >90% closure. No association with defect size or cleft type was identified. Conclusions : NRP monitoring is well-tolerated in young children following palatoplasty. Achieving velopharyngeal (VP) closure for >90% of stops is associated with a clinical assessment of adequate speech and VP function. Postoperative NRP testing may serve as a useful adjunct to clinical speech evaluation for early identification of children who require more intensive speech therapy or secondary palatal surgery.

    Cytophagic histiocytic panniculitis (CHP) is a rare form of nodular panniculitis that may progress to panniculitis-like T-cell lymphoma. We report a case of CHP that first manifested as bilateral ptosis, which is the first reported case of this presentation. A 25-year-old woman without medical history was referred to the neurology department of our hospital for evaluation of bilateral ptosis. Three months previously, she suddenly complained of bilateral ptosis without apparent cause. Simultaneously, non-painful tender subcutaneous nodules and eschar-like skin lesions were observed on her extremities and trunk. A diagnosis of CHP was made based on skin biopsy from the left thigh showing lobular panniculitis, vasculitis, and adiponecrosis, with infiltration of inflammatory cells, including lymphocytes, histiocytes, and phagocytic histiocytes. Her condition continued to worsen with corticosteroid and immunosuppressive agent (thalidomide) treatment. Significant improvement was noticed after three cycles of chemotherapy of THP-COP (pirarubicin, cyclophosphamide, vincristine, and prednisolone). CHP is a rare condition whose clinical presentation may include bilateral ptosis and biopsy is required for diagnosis of CHP.

    Submandibular gland ptosis is a common impediment to obtaining superior surgical aesthetic results in neck lift surgery. Techniques for suspending the submandibular gland have been proposed, but these procedures have the drawbacks of disturbing the floor of the mouth mucosa and periosteum. We present an approach of submandibular gland suspension for the treatment of gland ptosis by employing a platysma and hyoid bone fascia cradle. Our technique was performed on cadaveric models. The platysma muscle and hyoid bone cradle for submandibular gland ptosis was created on the left side of the neck in two cadavers. A submental incision with sharp dissection was performed to raise a supraplatysmal flap. A subplatysmal plane was developed until the submandibular gland was identified. Sutures were used to pexy the platysma to the hyoid bone periosteum and deep cervical fascia, tightening the overlying muscle and in turn elevating the submandibular gland. Submandibular gland ptosis must be corrected in order to achieve exemplary aesthetic results. Our approach of creating a cradle with the platysma and hyoid bone avoids the potential complications of previously described sling procedures, while still maintaining the integrity of the gland and surrounding tissues.

    Full Text Available Aim: To evaluate the effect of hollow bulb obturator prosthesis on articulation and nasalance in maxillectomy patients. Materials and Methods: A total of 10 patients, who were to undergo maxillectomy, falling under Aramany classes I and II, with normal speech and hearing pattern were selected for the study. They were provided with definitive maxillary obturators after complete healing of the defect. The patients were asked to wear the obturator for six weeks and speech analysis was done to measure changes in articulation and nasalance at four different stages of treatment, namely, preoperative, postoperative (after complete healing, that is, 3-4 months after surgery, after 24 hours, and after six weeks of providing the obturators. Articulation was measured objectively for distortion, addition, substitution, and omission by a speech pathologist, and nasalance was measured by Dr. Speech software. Results: The statistical comparison of preoperative and six weeks post rehabilitation levels showed insignificance in articulation and nasalance. Comparison of post surgery complete healing with six weeks after rehabilitation showed significant differences in both nasalance and articulation. Conclusion: Providing an obturator improves the speech closer to presurgical levels of articulation and there is improvement in nasality also.

  4. Nasal packing and stenting

    Weber, Rainer K.

    2009-01-01

    Full Text Available Nasal packs are indispensable in ENT practice. This study reviews current indications, effectiveness and risks of nasal packs and stents. In endoscopic surgery, nasal packs should always have smooth surfaces to minimize mucosal damage, improve wound healing and increase patient comfort. Functional endoscopic endonasal sinus surgery allows the use of modern nasal packs, since pressure is no longer required. So called hemostatic/resorbable materials are a first step in this direction. However, they may lead to adhesions and foreign body reactions in mucosal membranes. Simple occlusion is an effective method for creating a moist milieu for improved wound healing and avoiding dryness. Stenting of the frontal sinus is recommended if surgery fails to produce a wide, physiologically shaped drainage path that is sufficiently covered by intact tissue.

Patients and methods: A prospective comparative randomized single-center study enrolled 110 patients with bilateral congenital ptosis. One group (n=55 underwent AFLS and the second group (n=55 underwent GTS. Exclusion criteria were good levator function, absent Bell’s phenomenon, and abnormal ocular motility. Follow-up period was 2 years. Functional outcome was measured from digital photos by analysis of upper eyelid margin position relative to the superior limbus and classified as very good (<3 mm, good (3–5 mm, poor (>5 mm, and recurrent. Aesthetic outcome was assessed in terms of lid contour, symmetry of eyelid height, and lid crease presence. Complications were also reported. Results: Failure rate (recurrence and complications was less in AFLS (P=0.035. Symmetrical lid height and good contour were more frequently attained by AFLS (P=0.007 and 0.047, respectively. However, the frequency of very good, good, poor, recurrence, lagopthalmos, ectropion, infection, and formed lid crease individually showed no statistically significant difference (P=0.252, 0.482, 1, 0.489, 0.438, 1, 0.618, and 0.506, respectively. Conclusion: AFLS is a better choice in surgery for patients with bilateral congenital ptosis because it has fewer complications and a lesser recurrence rate than GTS.

    2016-08-01

    Full Text Available Dorsal nasal gouty tophus are rare occurrences with limited documentation. Here we report a male patient who has a history of poorly controlled gouty arthritis. He had nasal obstruction with an enlarging mass over his left nasal ridge for the past three years. Image studies revealed a nasal bone defect underneath the nasal lesion. The firm mass was excised and confirmed to be of gouty origin. The nasal bone defect was repaired with a titanium mesh plate to prevent nasal depression. He has fully recovered with no more nasal obstruction or recurrence of nasal tophus. The case report illustrates a common illness, gout, with a rare clinical manifestation leading to a common symptom, nasal obstruction. It demonstrates the importance of a detailed history, a thorough physical examination and most important of all, an extensive differential diagnosis in our clinical practice.

Congestion can also be caused by physical obstruction of nasal passages and/or modulation of sensory perception. Mucosal inflammation underlies many of the specific and interrelated factors that contribute to nasal congestion, as well as other symptoms of both allergic rhinitis and rhinosinusitis. A wide range of biologically active agents (eg, histamine, tumor necrosis factor-α, interleukins, cell adhesion molecules and cell types contribute to inflammation, which can manifest as venous engorgement, increased nasal secretions and tissue swelling/edema, ultimately leading to impaired airflow and the sensation of nasal congestion. Inflammation-induced changes in the properties of sensory afferents (eg, expression of peptides and receptors that innervate the nose can also contribute to altered sensory perception, which may result in a subjective feeling of congestion. Increased understanding of the mechanisms underlying inflammation can facilitate improved treatment selection and the development of new therapies for congestion.Keywords: allergic rhinitis, congestion, obstruction, pathophysiology, rhinosinusitis

    Structured Abstract Objectives To describe the perceptual speech outcomes from the Cleft Care UK (CCUK) study and compare them to the 1998 Clinical Standards Advisory Group (CSAG) audit. Setting and sample population A cross-sectional study of 248 children born with complete unilateral cleft lip and palate, between 1 April 2005 and 31 March 2007 who underwent speech assessment. Materials and methods Centre-based specialist speech and language therapists (SLT) took speech audio–video recordings according to nationally agreed guidelines. Two independent listeners undertook the perceptual analysis using the CAPS-A Audit tool. Intra- and inter-rater reliability were tested. Results For each speech parameter of intelligibility/distinctiveness, hypernasality, palatal/palatalization, backed to velar/uvular, glottal, weak and nasalized consonants, and nasal realizations, there was strong evidence that speech outcomes were better in the CCUK children compared to CSAG children. The parameters which did not show improvement were nasal emission, nasal turbulence, hyponasality and lateral/lateralization. Conclusion These results suggest that centralization of cleft care into high volume centres has resulted in improvements in UK speech outcomes in five-year-olds with unilateral cleft lip and palate. This may be associated with the development of a specialized workforce. Nevertheless, there still remains a group of children with significant difficulties at school entry. PMID:26567854

    Full Text Available Introduction. Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone - solitary osseous plasmacytoma, or in soft tissue - extramedullary plasmacytoma (EMP. EMP represents less than 1% of all head and neck malignancies. Case report. We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive difficulty in breathing through the nose and frequent heavy epistaxis on the right side. Nasal endoscopy showed dark red, soft, polypoid tumor in the last third of the right nasal cavity arising from the nasal septum. The biopsy showed that it was plasmacytoma. Bence Jones protein in the urine, serum electrophoresis, bone marrow biopsy, skeletal survey and other screening tests failed to detect multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely removed via an endoscopic approach, and then, 4 week later, radiotherapy was conducted with a radiation dose of 50 Gray. No recurrence was noted in a 3-year follow- up period. Conclusion. EMP of the nasal cavity, being rare and having long natural history, represents a diagnostic and therapeutic challenge for any ear, nose and throat surgeon. Depending on the resectability of the lesion, a combined therapy is the accepted treatment.

    We prospectively compared 120 patients who underwent either phacoemulsification or extracapsular cataract (ECCE) surgery to establish the incidence of postoperative ptosis between the two techniques. Of the 120 patients, 60 underwent ECCE (unpublished data 1989) and 60 had phacoemulsification. Data was collected prospectively on upper and lower margin reflex distance, upper lid skin crease and levator function, preoperatively and 6 weeks postoperatively. Photographs were taken pre and postoperatively and examined by a blinded observer. At 6 weeks, ptosis was present in 18% of ECCE patients compared with 0% in the phacoemulsification group. By changing from ECCE to phacoemulsification the incidence of postoperative ptosis has reduced. The possibility to induce postoperative ptosis remains, potential mechanisms are discussed.

    The purpose of this study was to collect nasalance scores for normal Korean-speaking children and adults and to determine whether age, vowel contexts, and stimulus length influence nasalance scores. Fifty-seven children aged 4-6 years and 17 adults participated in the study. Mean nasalance scores were obtained for eight sentences devoid of nasal consonants divided into the vowel/a/and/i/contexts; the sentences consisted of 4, 8, 16, and 31 syllables. All subjects were asked to repeat the speech stimuli twice after the examiner. The headset of the nasometer was replaced between the first and second recordings. An average value of the nasalance scores from the two recordings for each stimulus was calculated and used in the statistical analysis as a representative measure for each subject. Mean and standard deviations of nasalance scores were obtained for each speech stimulus and each age group. The statistical analysis indicated significant effects of age and vowel context and a significant interaction between age and the vowel context on nasalance scores. However, the effect of stimulus length on nasalance scores was not significant. All speakers had higher nasalance scores for the vowel/i/contexts than for the vowel/a/contexts. Adults had higher nasalance scores compared to children in both vowel contexts. These normal nasalance values from Korean-speaking children aged 4-6 years will provide important reference information for resonance assessment of children with cleft palate who have been considered for secondary palatal surgery. The results of the study suggest that subjects' age and the vowel content of speech stimuli should be carefully considered when interpreting the nasalance scores.

    Nasal obstruction can be due to internal and external valve problems that can be seen before and after rhinoplasty. The main scope of this article is to concentrate on surgical solutions to these problems. To overcome nasal obstruction at the internal valve, spreader grafts, spreader flaps, upper lateral splay graft, butterfly graft, flaring suture, M-plasty, Z-plasty, and suspension sutures have been described. The management of the external valve problems is possible by using lateral crural dissection and repositioning, lateral crural strut grafts, alar battens, lateral crural turn-in flap, alar rim grafts, and various other methods. It is not easy to decide which techniques would work best in every case. After a thorough examination and analysis, the underlying cause of the nasal obstruction can be understood, and one or multiple procedures can be chosen according to each individual problem.

    1984-01-01

    Aponeurotic defects and disinsertion of the levator aponeurosis are responsible for many cases of acquired ptosis. The typical clinical findings in aponeurotic defects are: history of prior orbital swelling, injury, ocular surgery, blepharochalasis; good to excellent levator function, thinning of the eyelid above the tarsus, high to absent lid crease, and normal Müller's muscle function. The purpose of the treatment is to repair a defect or advance the aponeurosis onto the tarsus. Levator aponeurosis surgery was used to treat 18 upper eyelids with acquired ptosis. Local anesthesia and surgery from an anterior approach were used in all cases. The advantages of this technique are: The lid height is determined by asking the patient to look in various fields of gaze. A blepharoplasty can be performed when necessary. The lid crease is formed. The exposition of the levator aponeurosis disinsertion is easier to recognize.

    Blepharophimosis ptosis epicanthus inversus syndrome (BPES) is a complex eyelid malformation characterized by the classical tetrad of blepharophimosis, telecanthus, ptosis, and epicanthus inversus. It has been reported to be associated with other ocular anomalies such as euryblepharon, strabismus, nystagmus, amblyopia, microphthalmos, lacrimal drainage apparatus abnormality, extra ocular muscle abnormalities, microcornea, trabecular dysgenesis, optic nerve hypoplasias, and colobomas of the optic disk. We describe a case of BPES with Axenfeld-Rieger syndrome, a neurocristopathy characterized by maldevelopment of the anterior segment with predisposition to development of glaucoma. Interestingly, both syndromes are caused by mutations in the same class of genes, namely the winged-helix/forked transcription factors (FOX) involved in a variety of developmental processes.

    To investigate the application of combining mastopexy and triple-plane breast augmentation in correction of breast ptosis and atrophy. Peri-areolar incision was performed to finish the fascia and dermal suspension to correct the breast ptosis. The implant was inserted under the pectoralis major muscle through lateral lower border of the gland and a "X" shape full thickness incision was made on the pectoralis major muscle according to the new position of nipple-areolar complex. 14 patients received combined mastopexy and triple-plane breast augmentation to correct breast atrophy and mastopexy simultaneously. All the patients were regularly followed for 6-12 months. No patients suffered severe complication and the results were satisfied. "Triple-plane" breast augmentation could be safely performed with peri-areolar mastopexy with minor injury. The technique could help to ensure the balance between the gland, nipple-areolar complex and the implant.

    Chronic Inflammatory Demyelinating Polyneuropathy is an autoimmune disease with progressive and relapsing courses. The main clinical presentations are diffuse deep tendon hyporeflexia or areflexia and symmetric proximal-distal muscles weakness. Myasthenia gravis is also an immune mediated disease with fluctuating ocular and bulbar symptoms and sometimes weakness. Although both myasthenia gravis and chronic inflammatory demyelinating polyneuropathy are immune mediated disorders, clinical presentations are obviously different in the two diseases. Herein, we will report a case of chronic inflammatory demyelinating polyneuropathy who presented with isolated unilateral ptosis. Initially, the patient was managed as ocular type of myasthenia gravis, but after progression to general limb weakness and areflexia, the diagnosis of chronic inflammatory demyelinating polyneuropathy was made. Although unilateral ptosis is a typical feature of myasthenia gravis, it may be seen as the first presentation of chronic inflammatory demyelinating polyneuropathy as well which mimics myasthenia gravis disease.

    2011-03-01

    The purposes of the study were to compare the temporal characteristics of nasalization between speakers with cleft palate with or without cleft lip and normal adult speakers and to investigate the relationship between acoustic temporal measures and perceived nasality. Fifteen speakers with cleft palate with or without cleft lip and 15 speakers without cleft palate aged 13 to 45 years participated in this study. Two listeners judged the degree of nasality in speakers with cleft palate with or without cleft lip. Two distinct acoustic energies derived from the mouth and nose were recorded simultaneously while speakers were producing the speech tasks /pimip/, /pamap/, and /pumup/. Absolute and proportional measures related to nasalization duration were obtained. Speakers with cleft palate with or without cleft lip exhibited more extensive acoustic nasalization in the time domain than did speakers without cleft palate with or without cleft lip. Speakers without cleft palate with or without cleft lip showed larger nasalization-duration ratios in the high vowel contexts than in the low vowel context. Speakers with cleft palate with or without cleft lip did not exhibit distinct differences in nasalization-duration ratios among the vowel contexts. The acoustic measurements reflecting temporal patterns of oral-nasal acoustic impedance were related to the perception of hypernasality. These results suggest that the speakers with cleft palate with or without cleft lip showed longer duration of acoustic nasalization than speakers without cleft palate with or without cleft lip. Temporal characteristics of acoustic nasalization grew longer as the degree of perceived hypernasality increased. The positive correlation between temporal measures of acoustic nasalization and degree of perceived nasality suggests that temporal measures of nasalization would provide supplementary diagnostic information in relation to the degree of hypernasality.

    Severe congenital ptosis is commonly associated with poor levator function. This study compares the functional and cosmetic outcomes of open versus closed frontalis sling using Gore-Tex in the treatment of such conditions. Randomized interventional comparative case series of 20 eyes of 13 patients with severe congenital ptosis with levator excursion Gore-Tex string sutures either through a skin crease incision (group 1) or supraciliary incisions (group II). Mean age was 5.10 ± 3.10 years in group I and 7.30 ± 4.47 years in group II. Ptosis was unilateral in six patients and bilateral in seven patients. Following surgery, there was a statistically significant improvement in the palpebral fissure width (PFW) and marginal reflex distance (MRD) in both groups (p value 0.001) with better functional outcome in group II (closed approach). The cosmetic results were better in group I (open approach). The mean operative time in group II was 18.1 ± 2.4 min, which was significantly shorter than group I (30.2 ± 3.1 min). No recurrence or grave complications were encountered during follow-up. Gore-Tex is a useful sling material for correction of severe congenital ptosis due to poor frontalis action. Open transcrease approach is recommended in absence of lid crease whereas closed approach is better used in cases with preserved crease due to its superior functional outcome.

De los 10 casos, 7 fueron bilaterales y 3 unilaterales. En todos ellos la función del elevador se situaba entre 4 y 8 mm y el grado de ptosis fue mayor de 4 mm con disminución del campo visual en la mirada directa. La técnica quirúrgica incluyó un abordaje cutáneo mediante la incisión horizontal de Blefaroplastia superior, la exposición amplia del músculo elevador y su aponeurosis, respetando las bolsas grasas orbiculares y separándolo de la conjuntiva palpebral. En todos los casos se obtuvo corrección de las ptosis. El grado de asimetría fue inferior a 0,3 cm. Un caso presentó en el postoperatorio inmediato dehiscencia de la sutura en su lado medial y tuvo que ser reintervenido a los 10 días. El edema palpebral postoperatorio se resolvió a partir del 2º día postoperatorio desapareciendo hacia el día 8º y permitiendo una valoración fiable en dicha fecha. El grado de satisfacción de los paciente fue bueno o muy bueno y el campo visual fue completo en todos los pacientes Las técnicas clásicas y sus modificaciones para la corrección de los casos de ptosis siguen teniendo validez. Con esta modificación que respeta la conjuntiva palpebral ocular se evita añadir morbilidad al proceso quirúrgico.

    Nasal polyps are smooth outgrowths assuming a shape of grapes, formed from the nasal mucosa, limiting air flow by projecting into a lumen of a nasal cavity. Up to now the surgical resection is the best method of their treatment, but etiology and pathogenesis of the nasal polyps is not yet fully established. The aim of the study was the assessment of the selected lysosomal exoglycosidases activity in the nasal polyps. In this study the activity of β-galactosidase, α-mannosidase and α-fucosidase was determined in the tissue of the nasal polyps obtained from 40 patients (10F, 30M) and control tissues derived from mucosa of lower nasal conchas obtained during mucotomy from 20 patients (10F, 10M). We observed significant lower values of GAL, FUC and tendency to decrease of MAN and GLU concentration in nasal polyps (P) in comparison to control healthy nasal mucosa (C). In nasal polyp tissue (P) no differences of GAL, MAN and FUC specific activity in comparison to control mucosa (C) were found. Our research supports bioelectrical theory of the nasal polyps pathogenesis and directs attention at research on glycoconjugates and glycosidases of the nasal mucosa extracellular matrix.

    A 12-year-old boy had problems with his speech due to a defect in the soft palate. This defect was caused by the surgical removal of a synovial sarcoma. Testing with a nasometer revealed hypernasality above normal values. Given the size and severity of the defect in the soft palate, the possibility of improving the speech with speech therapy was limited. At a centre for special dentistry an attempt was made with a prosthetic construction to improve the performance of the palate and, in that way, the speech. This construction consisted of a denture with an obturator attached to it. With it, an effective closure of the palate could be achieved. New measurements with acoustic nasometry showed scores within the normal values. The nasality in the speech largely disappeared. The obturator is an effective and relatively easy solution for palatal insufficiency resulting from surgical resection. Intrusive reconstructive surgery can be avoided in this way.

    Hypernasality is one of the most detrimental speech disturbances that lead to declines of speech intelligibility. Velopharyngeal inadequacy, which is associated with anatomic defects such as cleft palate or neuromuscular disorders that affect velopharygneal function, is the primary cause of hypernasality. A simulation study by Rong and Kuehn [J. Speech Lang. Hear. Res. 55(5), 1438-1448 (2012)] demonstrated that properly adjusted oropharyngeal articulation can reduce nasality for vowels synthesized with an articulatory model [Mermelstein, J. Acoust. Soc. Am. 53(4), 1070-1082 (1973)]. In this study, a speaker-adaptive articulatory model was developed to simulate speaker-customized oropharyngeal articulatory adaptation to compensate for the acoustic effects of nasalization on /a/, /i/, and /u/. The results demonstrated that (1) the oropharyngeal articulatory adaptation effectively counteracted the effects of nasalization on the second lowest formant frequency (F2) and partially compensated for the effects of nasalization on vowel space (e.g., shifting and constriction of vowel space) and (2) the articulatory adaptation strategies generated by the speaker-adaptive model might be more efficacious for counteracting the acoustic effects of nasalization compared to the adaptation strategies generated by the standard articulatory model in Rong and Kuehn. The findings of this study indicated the potential of using oropharyngeal articulatory adaptation as a means to correct maladaptive articulatory behaviors and to reduce nasality.

    Many patients with cleft palate deformities worldwide receive treatment at a later age than is recommended for normal speech to develop. The outcomes after late palate repairs in terms of speech and quality of life (QOL) still remain largely unstudied. In the current study, questionnaires were used to assess the patients' perception of speech and QOL before and after primary palate repair. All of the patients were operated at a cleft center in northeast India and had a cleft palate with a normal lip or with a cleft lip that had been previously repaired. A total of 134 patients (7-35 years) were interviewed preoperatively and 46 patients (7-32 years) were assessed in the postoperative survey. The survey showed that scores based on the speech handicap index, concerning speech and speech-related QOL, did not improve postoperatively. In fact, the questionnaires indicated that the speech became more unpredictable (P after surgery. A total of 78% of the patients were still satisfied with the surgery and all of the patients reported that their self-confidence had improved after the operation. Thus, the majority of interviewed patients who underwent late primary palate repair were satisfied with the surgery. At the same time, speech and speech-related QOL did not improve according to the speech handicap index-based survey. Speech predictability may even become worse and nasal regurgitation may increase after late palate repair, according to these results.

    A case of mycotic bovine nasal granuloma in a 10 year-old Jersey cow, produced by Drechslera halodes is presented. Histopathological sections showed abundant hyaline and pigmented extra and intracellular fungal structures together with a polymorphic cellular granuloma formed by neutrophils, lymphocytes, plasmocytes, histiocytes and giant cells of the Langhans type. It is the first case of mycotic bovine nasal granuloma recognized in Uruguay although this disease seems to be frequent according to the opinion of veterinarian specialists.

    Full Text Available Introduction: To evaluate the cosmetic results and recurrence of unilateral frontalis sling surgery using a silicone rod compared with autogenous fascia lata in cases of simple congenital ptosis. Methods: This is a retrospective comparative study of 59 patients who underwent a frontalis sling operation for congenital ptosis. Patients were divided into two groups according to the sling material used; an autogeneous fascia lata (fl group (n = 24 and a silicone rod group (sl (n = 35. Cosmetic results and recurrence rates were compared between these 2 groups. The cosmetic results of the frontalis sling operation were assessed as good, fair, or poor based on the difference between the Margin Reflex Distance of both eyelids and graded as good if the difference in two eyes was ≤1mm and poor if it was 2mm or more. Recurrence was defined as the conversion of the cosmetic result from good or fair to poor category. Results: At postoperative day seven and 30, MRD of both the groups were good but on three months follow-up MRD of silicon rod group dropped, however it was not statistically significant .Lid contour was good in both the groups, however, lid symmetry was poor in two cases of fascia lata at three months follow-up. Repeat surgery for poor outcome was done in 8.6% of cases in silicon rod and 8.3% of fascia lata group. Conclusions: The frontalis sling operation using either a silicone rod or autogenous fascia lata showed equally good cosmetic results and lower recurrence rate at three months follow up. Keywords: congenital ptosis; fascia lata; frontalis sling surgery; margin reflex distance; silicone rod.

  7. Diplopia and variable ptosis as the sole initial findings in a case of orbital plasmacytoma and multiple myeloma.

    Plasmacytomas are monoclonal plasma cell tumors. They represent 3% of all orbital tumors. We present an unusual case of orbital plasmacytoma and advanced multiple myeloma where the sole presenting symptoms were those of diplopia and ptosis. Clinical examination revealed right hypertropia and variable left upper lid ptosis but no proptosis. The visual acuity and the rest of the ocular examination were normal in both eyes. An MRI scan of the brain and orbits revealed a frontal bone lesion consistent with a plasmacytoma. A bone marrow biopsy showed a light chain multiple myeloma with free lambda light chains. Although the literature reports diplopia and ptosis as being clinical features of orbital plasmacytomas, to our knowledge this is the first reported case where these symptoms were the only presenting features, despite widespread disease.

    Full Text Available Os fonoaudiólogos que atuam no campo da Motricidade Orofacial atendem com frequência, pacientes com obstrução nasal; entretanto, nem sempre o acesso ao profissional responsável pelo diagnóstico otorrinolaringológico é fácil. O Peak Nasal Inspiratory Flow é um instrumento barato, de fácil manuseio, amplamente citado na literatura internacional, que tem por objetivo avaliar a patência nasal. O objetivo do presente estudo foi realizar uma revisão da literatura acerca do Peak Nasal Inspiratory Flow, fornecendo subsídios para reflexões acerca de seu emprego nos distúrbios miofuncionais orofaciais e cervicais. Para tanto, foi realizada uma revisão da literatura nas bases de dados Medline, Cochrane Library, LILACS e SciELO empregando-se os descritores peak, inspiratory, nasal e flow. O Peak Nasal Inspiratory Flow mostrou-se uma técnica simples, barata, validada e com boa reprodutibilidade. Parece, portanto, tratar-se de um instrumento útil para avaliação da patência nasal, apesar de algumas limitações, fornecendo dados complementares ao diagnóstico miofuncional orofacial e cervical. Entretanto, estudos clínicos precisam ser conduzidos para que se comprove ou refute a hipótese.The speech-language pathologists that work in the Orofacial Myology field frequently have patients with nasal obstruction; however, the access to the professional responsible for the diagnosis can be difficult at times.

    Speech is the predominant means of communication between human beings and since the invention of the telephone by Alexander Graham Bell in 1876, speech services have remained to be the core service in almost all telecommunication systems. Original analog methods of telephony had the disadvantage of speech signal getting corrupted by noise, cross-talk and distortion Long haul transmissions which use repeaters to compensate for the loss in signal strength on transmission links also increase the associated noise and distortion. On the other hand digital transmission is relatively immune to noise, cross-talk and distortion primarily because of the capability to faithfully regenerate digital signal at each repeater purely based on a binary decision. Hence end-to-end performance of the digital link essentially becomes independent of the length and operating frequency bands of the link Hence from a transmission point of view digital transmission has been the preferred approach due to its higher immunity to noise. The need to carry digital speech became extremely important from a service provision point of view as well. Modem requirements have introduced the need for robust, flexible and secure services that can carry a multitude of signal types (such as voice, data and video) without a fundamental change in infrastructure. Such a requirement could not have been easily met without the advent of digital transmission systems, thereby requiring speech to be coded digitally. The term Speech Coding is often referred to techniques that represent or code speech signals either directly as a waveform or as a set of parameters by analyzing the speech signal. In either case, the codes are transmitted to the distant end where speech is reconstructed or synthesized using the received set of codes. A more generic term that is applicable to these techniques that is often interchangeably used with speech coding is the term voice coding. This term is more generic in the sense that the

    Full Text Available Snakebite is an environmental hazard associated with a significant morbidity and mortality. Two main types of toxicity occur due to snakebite, namely vasculotoxicity and neurotoxicity. Neurotoxic snakebites present mainly with bilateral ptosis with dilated pupils and/or difficulty in breathing. Jatropha curcas belongs to the family Euphorbiaceae and is commonly referred to as " Ratanjyot" in Gujarati. It has got many medicinal uses such as anticancerous properties and bio-oil. There are very few cases of its toxicity in adults. Toxicity from it causes meiosis, vomiting, diarrhea, etc., We will hereby discuss one such patient who consumed J. curcas seeds intentionally, became drowsy and accidentally got bit by a snake, and then, the patient started having bilateral ptosis, but with normal-sized pupils. There is no case reported yet in the literature mentioning the combined toxicity of snakebite and J. curcas, so we thought to publish this first case report of its kind in the world, thus discussing its diagnosis, symptoms, and treatment modalities.

    Fernando Passos Rocha

    Full Text Available CONTEXT: Congenital deformities of the anterior thoracic wall are characterized by unusual development of the costal cartilages. All these medical conditions are frequently associated with a variety of breast deformities. Several surgical techniques have been described for correcting them, going from sternochondroplasty to, nowadays, minimally invasive techniques and silicone prosthesis implantation. CASE REPORT: The present article reports the case of a young female patient who presented bilateral mammary ptosis and moderate pectus excavatum that caused a protrusion between the eighth and the tenth ribs and consequent esthetic disharmony. The proposed surgical treatment included not only subglandular breast implants of polyurethane, but also resection of part of the rib cartilage and a bone segment from the eighth, ninth and tenth ribs by means of a single submammary incision in order to make the scar minimally visible. Correction through a single incision benefited the patient and provided an excellent esthetic result. CONCLUSIONS: The techniques used to repair bilateral mammary ptosis and pectus excavatum by plastic and thoracic surgery teams, respectively, have been shown to be efficient for correcting both deformities. An excellent esthetic and functional result was obtained, with consequent reestablishment of the patient's self-esteem.

Study subjects Patients with congenital ptosis, aged 18 years or younger, during the period under study (2005–2011) at the Singapore National Eye Centre. Methods Review of case records for functional and cosmetic outcome measures after frontalis suspension surgery using either SRs or autologous FL. Results A total of 18 patients were studied (14 eyelids had FL, 16 eyelids had SRs) with mean ages of 7.1 (range 5–12) and 7.2 (range 4–18) years for the FL and SR groups, respectively. Mean follow-up period was 41.6 (range 11.2–77.9) and 48.6 (16.1–87.4) months, respectively. Patients in the FL group had better functional and cosmetic results compared to those in silicone group, with no recurrence of ptosis. More complications were experienced by patients in the SR group. Conclusion Autologous FL for frontalis suspension remains an excellent choice for (and should be considered as useful surgical armamentarium for) repair of severe congenital ptosis. PMID:27695282

    A women's breast is a sex-specific and aesthetic bodily attribute. It is suggested that breast morphology signals maturity, health, and fecundity. The perception of a woman's attractiveness and age depends on various cues, such as breast size or areola pigmentation. Conducted in Poland and Papua, the current study investigated how breast attractiveness, and the further estimate of a woman's age based on her breast's appearance, is affected by the occurrence of breast ptosis (ie, sagginess, droopiness). In the Polish sample, 57 women and 50 men (N = 107) were presented with sketches of breasts manipulated to represent different stages of ptosis based on two different breast ptosis classifications. The participants were asked to rate the breast attractiveness and age of the woman whose breasts were depicted in each sketch. In Papua, 45 men aged 20 to 75 years took part in the study, which was conducted using only one of the classifications of breast ptosis. Regardless of the classification used, the results showed that the assessed attractiveness of the breasts decreased as the estimated age increased with respect to the more ptotic breasts depicted in the sketches. The results for Papuan raters were the same as for the Polish sample. Breast ptosis may be yet another physical trait that affects the perception and preferences of a potential sexual partner. The consistency in ratings between Polish and Papuan raters suggests that the tendency to assess ptotic breasts with aging and a loss of attractiveness is cross-culturally universal. © 2017 Wiley Periodicals, Inc.

    Full Text Available Congenital ptosis (CP represents a significant reconstructive problem Numerous studies have not yet provided full and satisfactory results. In this study, we have presented our experience in the surgical treatment of 108 patients by the use of Son Ye Guang's modified method - frontal muscle transposition. A total of 108 patients with CP were surgically treated at the Clinic for Plastic Surgery and Burns of the Military Medical Academy in the period 1991-2000. Unilateral ptosis was operated in 85 patients, and bilateral in 23 patients. CP was more frequently found in males (58.34% than in females (41.66%. The youngest patient was only 5.5 years old, and the oldest was 42, the average age was 21.3 years. All patients were operated on by the same surgeon, and were monitored monthly during the first six months and then twice a year for the next 3 years. Postoperative results were evaluated after 6 months: the action of raising the eyelids was compared to the full amplitude of movement of the eye on the healthy side. The closure of the eyelids and the symmetry of the palpebral fissure in a steady horizontal view was also assessed. The action of the opening as well as closure of the eyelids in full amplitude was obtained in all operated patients. Asymmetry of the palpebral fissure in a steady horizontal view up to 1 mm did not require additional correction. In 9 cases, asymmetry of the palpebral fissure greater than 1 mm was subsequently corrected. The advantages of this surgical method compared to the other, previously described techniques, were emphasized in the conclusion. The main advantage was the elimination of postoperative lagophthalmos, which represented the problem in all previously used methods.

    Larson, P L; Hamlet, S L

    1987-10-01

    Nasal coarticulation in phonetically controlled nonsense syllables was investigated in four normal adult speakers. Nasalization was determined using the ratio of a nasal accelerometer signal amplitude to airborn microphone signal amplitude. Measurements of nasalization were made at the midpoint of vowels and at a constant time from the nasal consonant. Nasal acoustical coupling was greater for high vowels than for low vowels in all consonant contexts. Nasalization was also greater for vowels between two nasal consonants than for vowels between a nasal consonant and a fricative or stop. Results for progressive versus regressive assimilation depended on the measurement strategy. For within-vowel measurements made a constant time from the nasal consonant, prenasal vowels showed greater nasalization than postnasal vowels. This nasal accelerometric technique shows promise for clinical assessment of articulatory details of velar function.

    Anne Birgitta Nilsen

    2014-12-01

    Full Text Available The manifesto of the Norwegian terrorist Anders Behring Breivik is based on the “Eurabia” conspiracy theory. This theory is a key starting point for hate speech amongst many right-wing extremists in Europe, but also has ramifications beyond these environments. In brief, proponents of the Eurabia theory claim that Muslims are occupying Europe and destroying Western culture, with the assistance of the EU and European governments. By contrast, members of Al-Qaeda and other extreme Islamists promote the conspiracy theory “the Crusade” in their hate speech directed against the West. Proponents of the latter theory argue that the West is leading a crusade to eradicate Islam and Muslims, a crusade that is similarly facilitated by their governments. This article presents analyses of texts written by right-wing extremists and Muslim extremists in an effort to shed light on how hate speech promulgates conspiracy theories in order to spread hatred and intolerance.The aim of the article is to contribute to a more thorough understanding of hate speech’s nature by applying rhetorical analysis. Rhetorical analysis is chosen because it offers a means of understanding the persuasive power of speech. It is thus a suitable tool to describe how hate speech works to convince and persuade. The concepts from rhetorical theory used in this article are ethos, logos and pathos. The concept of ethos is used to pinpoint factors that contributed to Osama bin Laden's impact, namely factors that lent credibility to his promotion of the conspiracy theory of the Crusade. In particular, Bin Laden projected common sense, good morals and good will towards his audience. He seemed to have coherent and relevant arguments; he appeared to possess moral credibility; and his use of language demonstrated that he wanted the best for his audience.The concept of pathos is used to define hate speech, since hate speech targets its audience's emotions. In hate speech it is the

    Full Text Available Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical and complementary investigation of vascular leiomyoma in the nasal cavity. Resumed Report We present the case of a 49-year-old woman diagnosed with vascular leiomyoma in the nasal cavity, which manifested mainly with nasal obstruction. During investigation, computer tomography was not diagnostic, the cytologic study was not conclusive, and according to the biopsy, it was a squamous papilloma. Conclusion We suggest that the technical difficulty in obtaining an adequate amount of material for preoperative biopsy, associated with the topography of the lesion in the vestibular nasal region, may have contributed to changing the postoperative diagnosis. Thus, pathologic study of the surgical fragment is the more accurate method for diagnosis.

    Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical and complementary investigation of vascular leiomyoma in the nasal cavity. Resumed Report We present the case of a 49-year-old woman diagnosed with vascular leiomyoma in the nasal cavity, which manifested mainly with nasal obstruction. During investigation, computer tomography was not diagnostic, the cytologic study was not conclusive, and according to the biopsy, it was a squamous papilloma. Conclusion We suggest that the technical difficulty in obtaining an adequate amount of material for preoperative biopsy, associated with the topography of the lesion in the vestibular nasal region, may have contributed to changing the postoperative diagnosis. Thus, pathologic study of the surgical fragment is the more accurate method for diagnosis. PMID:25992133

    The aim of this study was to develop and validate the first ever speech-specific perceptual speech-evaluation tool for patients with head and neck cancer. Five speech parameters (intelligibility, articulation, speech rate, nasality, and asthenia) and overall grade were included and evaluated. Speech samples of 117 subjects were recorded on electroglottograph equipment using a standard protocol and were independently judged and rated by 3 experienced speech and language therapists and re-rated 12 weeks apart. Among patients the Cronbach's alpha (α) coefficients for internal consistency for connected speech were 0.89, whereas for single words the α coefficients ranged between 0.80 and 0.84. The Spearman's correlation coefficients for intra-rater reliability for connected speech and words varied between 0.30 and 0.90 and 0.49 and 0.76, respectively, whereas for inter-rater reliability the coefficients ranged between 0.53 and 0.99 and 0.56 and 0.99, respectively. For construct validity, the Spearman's correlation coefficient ranged between 0.41 and 0.55. The London Speech Evaluation (LSE) scale demonstrated a high reliability and validity in our cohort of patients with head and neck cancer. surgery. Copyright © 2011 Wiley Periodicals, Inc.

    We live in a noisy world! In all applications (telecommunications, hands-free communications, recording, human-machine interfaces, etc.) that require at least one microphone, the signal of interest is usually contaminated by noise and reverberation. As a result, the microphone signal has to be ""cleaned"" with digital signal processing tools before it is played out, transmitted, or stored.This book is about speech enhancement. Different well-known and state-of-the-art methods for noise reduction, with one or multiple microphones, are discussed. By speech enhancement, we mean not only noise red

    The purpose of this study is to describe the speech characteristics in an English-speaking Ugandan boy of 4.5 years who has a rare paramedian craniofacial cleft (unilateral lip, alveolar, palatal, nasal and maxillary cleft, and associated hypertelorism). Closure of the lip together with the closure of the hard and soft palate (one-stage palatal closure) was performed at the age of 5 months. Objective as well as subjective speech assessment techniques were used. The speech samples were perceptually judged for articulation, intelligibility and nasality. The Nasometer was used for the objective measurement of the nasalance values. The most striking communication problems in this child with the rare craniofacial cleft are an incomplete phonetic inventory, a severely impaired speech intelligibility with the presence of very severe hypernasality, mild nasal emission, phonetic disorders (omission of several consonants, decreased intraoral pressure in explosives, insufficient frication of fricatives and the use of a middorsum palatal stop) and phonological disorders (deletion of initial and final consonants and consonant clusters). The increased objective nasalance values are in agreement with the presence of the audible nasality disorders. The results revealed that several phonetic and phonological articulation disorders together with a decreased speech intelligibility and resonance disorders are present in the child with a rare craniofacial cleft. To what extent a secondary surgery for velopharyngeal insufficiency, combined with speech therapy, will improve speech intelligibility, articulation and resonance characteristics is a subject for further research. The results of such analyses may ultimately serve as a starting point for specific surgical and logopedic treatment that addresses the specific needs of children with rare facial clefts.

    Twenty cases of nasal bone fractures were evaluated as to the types of fractures based upon HRCT findings. Conventional X-Ray films for nasal bones were analyzed and compared with HRCT findings. Nasal bone fractures were classified into lateral and frontal fractures. HRCT images were evaluated in three planes including upper, middle and lower portions of the nasal bone. Fractures favored males of teens. Lateral fracture gave rise to the fractures of the nasal bone opposite to the external force, loosening of the ipsilateral nasomaxillary sutures and fractures of the frontal process of the maxilla. Conventional X-Ray films were reevaluated after HRCT evaluation and indications of nasal bone fractures were determined. In addition to the discontinuity of the nasal dorsum, fracture lines parallel to and beneath the nasal dorsum and indistinct fracture lines along the nasomaxillary sutures are the indication of nasal bone fractures by conventional X-Ray films.

    Introduction. The objective of this investigation was to evaluate the reliability and validity of the NasalView system as a screening tool for hypernasality within the scope of a routine diagnostic procedure in cleft lip and palate patients. Material and Methods. In a collective of 95 patients with cleft and lip palate ranging from 4 to 25 years of age, hypernasality was exploited perceptually, patients were classified in four degrees, and nasalance was measured objectively with the NasalView system. Speech stimuli existed in one nasal and one nonnasal sentence; nasalance ratio and distance were calculated. Results. The test-retest error was within a range of 2%. Sensitivity ranged from 83.3% to 91.1% for the nonnasal sentence, from 70% to 78.4% for nasalance ratio and from 68.1% to 81.1% for nasalance distance. Specifity ranged from 87% to 93.1% for the nonnasal sentence, from 69.6% to 97.5% for nasalance ratio, and from 70.7% to 73.9% for nasalance distance. Conclusions. With a quick and gentle screening procedure, it is easily possible to identify hypernasal patients by an objective diagnostic tool of hypernasality, the NasalView system, with good reliability and validity.

    BACKGROUND: The velopharyngeal sphincter (VPS) plays the main role in speech formation. The cleft palate, due to the damage of the soft palate, leads to dysfunction of the velopharyngeal sphincter thus causing speech disorder. AIM: To establish a link between the nasal air escape and the perceptual symptoms in the speech of patients with cleft palate or cleft lip and palate using auditory-visual perceptual procedures for determining the influence the velopharyngeal dysfunction has on speech. MATERIAL AND METHODS: Twenty patients with speech disorders, out of which 10 have cleft palate or cleft lip and palate (experimental group), participated in the perceptual assessment by means of Czermak mirror fogging test for assessing the nasal air escape and Pittsburgh Weighted Speech Scale (PWSS) for assessing the probable nature of the velopharyngeal sphincter. RESULTS: The respondents with a considerable nasal air escape have a higher velopharyngeal inability, that is, probably incompetent nature of the velopharyngeal sphincter. There is a strong correlation between the nasal air escape and the probable nature of the velopharyngeal sphincter (the coefficient of linear correlation r = 0.9756). The calculated p-value is p = 0.000002. CONCLUSION: The perceptual speech symptoms and the nasal air escape provide unique insight into the state and role the velopharyngeal sphincter has in speech.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    There are several methodology based on voice analysis to evaluate nasal airway. Here we introduce a new quantitative index based on voice spectrum analysis to evaluate nasal obstruction. Ten subjects of nasal blockage were instructed to produced the sustained consonant-vowel syllable /m partial partial differential/ at comfortable levels of speech for at least 5 seconds. After nasal decongestant treatment, the second voice sample was collected. Sound spectrum was obtained by the algorithm of fast Fourier transform and the fundamental frequency (F0) was calculated by the method of autocorrelation. Voice low tone to high tone ratio (VLHR) was defined as the division of low frequency power (LFP) into high frequency power (HFP) of the sound power spectrum and was finally expressed in decibels. The cut-off frequency was the product of F0 and square root of (4 x 5). The VLHR after nasal decongestant treatment increased significantly as compared with that before treatment (P < 0.01). VLHR is a new index derived from sound spectral analysis and that may detect the changes in frequency characteristics of voice during treatment for nasal obstruction. The index is quantitative, non-invasive, and potentially useful for basic researches and clinical applications.

    2009-01-01

    This study investigated the effects of altered fundamental frequency (F0) on nasalance levels of the vowels /i/ and /a/ produced by adults without cleft palate within a controlled sound pressure level (SPL) range. A prospective group design with convenience sampling from the University of North Carolina at Chapel Hill was used. 20 men and 20 women participated, aged 18 to 55 years. All were native English speakers with normal speech and language skills and adequate velopharyngeal function. The outcome measures were percentage nasalance obtained from the Nasometer 6200 (KayPentax) headset and the Computerized Speech Lab Model 4400 (CSL, KayPentax) during vowel production while speakers (1) targeted an SPL range of 75 to 85 dB and (2) targeted the SPL plus F0 range of 165 to 175 Hz. A significant univariate effect was found for the vowels /i/ and /a/ in the targeted SPL condition such that /i/ was produced with higher nasalance than /a/. A significant univariate effect was also found during production of /a/ in the targeted SPL plus F0 condition such that men produced /a/ with higher nasalance than women did. SPL appears to largely account for percentage nasalance differences between the vowels /i/ and /a/ produced by adult male and female speakers. Increased F0 by male speakers appears to influence percentage nasalance during production of the vowel /a/. Clinical implications in regard to assessment of hypernasality are discussed.

    Hypernasality is associated with various diseases and interferes with speech intelligibility. A recently developed quantitative index called voice low tone to high tone ratio (VLHR) was used to estimate nasalization. The voice spectrum is divided into low-frequency power (LFP) and high-frequency power (HFP) by a specific cutoff frequency (600 Hz). VLHR is defined as the division of LFP into HFP and is expressed in decibels. Voice signals of the sustained vowel [a :] and its nasalization in eight subjects with hypernasality were collected for analysis of nasalance and VLHR. The correlation of VLHR with nasalance scores was significant (r = 0.76, p < 0.01), and so was the correlation between VLHR and perceptual hypernasality scores (r = 0.80, p < 0.01). Simultaneous recordings of nasal airflow temperature with a thermistor and voice signals in another 8 healthy subjects showed a significant correlation between temperature rate of nasal airflow and VLHR (r = 0.76, p < 0.01), as well. We conclude that VLHR may become a potential quantitative index of hypernasal speech and can be applied in either basic or clinical studies.

    The frontalis suspension technique is the surgical method of choice in patients with ptosis and a levator function of 4 mm or less. Several types of materials have been used, including Gore-Tex(®), which has been used successfully as a frontalis sling material since 1986. Recently, a Gore-Tex sheet (wider than a sling or strip) suspension was reported. This paper reports the results of 27 eyes from 20 patients with congenital ptosis treated using the frontalis suspension technique with the newly developed Gore-Tex Most Versatile Patch (MVP) sheet. All patients underwent surgery between April 2007 and September 2011 and were followed up for at least one year. The average follow-up duration was 18 months, with a range of 12-36 months. The average patient age was 45 (5-85) years, and the group included 11 males and nine females. Thirteen cases demonstrated ptosis in one eye, and seven cases involved both eyes. The patients were divided by age into a younger group and an older group. All ptosis procedures were performed using the Gore-Tex MVP sheet. The implant was normally 7 mm wide for adults and 5 mm wide for children. The implantation method was the same as that used for the sheet shape fascia. In all patients, satisfactory functional results were observed at the 6-month follow-up examination. Eyelid opening heights were also obtained. The average marginal reflex distance (MRD) was -0.5 mm preoperatively, which improved to +1.9 mm after surgery. After one year, average MRD was +1.6 mm. MRD attenuation was more frequent in the younger group. There were no cases requiring redo surgery and only one case of exposure.

    2015-01-01

    Background: Patients with moderate to severe ptosis are often considered poor candidates for nipple-sparing mastectomy. This results from the perceived risk of nipple necrosis and/or the inability of the reconstructive surgeon to reliably and effectively reposition the nipple-areola complex on the breast mound after mastectomy. Methods: A retrospective review identified patients with grade II/III ptosis who underwent nipple-sparing mastectomy with immediate perforator flap reconstruction and subsequently underwent a mastopexy procedure. The mastopexies included complete, full-thickness periareolar incisions with peripheral undermining around the nipple-areola complex to allow for full transposition of the nipple-areola complex relative to the surrounding skin envelope. Results: Seventy patients with 116 nipple-sparing mastectomies met inclusion criteria. The most common complications were minor incisional dehiscence (7.7 percent) and variable degrees of necrosis in the preserved breast skin (3.4 percent) after the initial mastectomy. There were no cases of nipple-areola complex necrosis following the secondary mastopexy. Conclusions: The authors demonstrate that full mastopexy, including a complete full-thickness periareolar incision and nipple-areola complex repositioning on the breast mound, can be safely performed after nipple-sparing mastectomy and perforator flap breast reconstruction. The underlying flap provides adequate vascular ingrowth to support the perfusion of the nipple-areola complex despite complete incisional interruption of the surrounding cutaneous blood supply. These findings may allow for inclusion of women with moderate to severe ptosis in the candidate pool for nipple-sparing mastectomy if oncologic criteria are otherwise met. These findings also represent a significant potential advantage of autogenous reconstruction over implant reconstruction in women with breast ptosis who desire nipple-sparing mastectomy.

    Background Blepharophimosis ptosis epicanthus inversus syndrome (BPES) is a rare congenital ophthalmic disorder,characterized by congenital eyelid malformation including bilateral ptosis, shortening of the horizontal eyelid fissure,epicanthus inversus, and increased distance between the inner canthi. In this research, we studied the histological structure and ultrastructure of medial canthal ligament of patients with BPES.Methods Thirty patients with BPES who received plastic surgery at the Zhongshan Ophthalmic Center from March 2006 to January 2008 were studied. There were 17 males and 13 females with an average age of (8.73±3.37) years (3-31 years). The medial canthal ligaments of patients were collected during the plastic surgery to analyze the histological structure by hematoxylin and eosin (HE), Congo red, van Gieson's (VG), Masson trichrome and aldehyde-fuchsin staining. The ultrastructures of the medial canthal ligaments were also analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Fifteen samples of medial canthal ligament from healthy persons with an average age of (9.02±3.12) years (6-30 years) were collected as a control group.Results Morphological and histological study showed that the medial canthal ligaments of BPES patients were composed of collagen fibers, a few elastic fibers and striated muscles. The collagen fibers assemblies were disorganized and the fibrous connective tissues were undergoing hyaline degeneration. The karyopycnosis of fibroblasts was located among the collagen fibrils and the numbers of fibroblasts were decreased. Ultrastructural study with SEM showed that the collagen fibers were larger than normal, irregular and loose. Parts of the collagen fibers were broken and had a coarse surface. Ultrastructural study with TEM showed that the fibroblasts had less cytoplasm, fewer organelles and the nucleus displayed pyknosis.Conclusions The medial canthal ligament in BPES patients is composed

    Ubiquitination plays a crucial role in neurodevelopment as exemplified by Angelman syndrome, which is caused by genetic alterations of the ubiquitin ligase-encoding UBE3A gene. Although the function of UBE3A has been widely studied, little is known about its paralog UBE3B. By using exome and capillary sequencing, we here identify biallelic UBE3B mutations in four patients from three unrelated families presenting an autosomal-recessive blepharophimosis-ptosis-intellectual-disability syndrome characterized by developmental delay, growth retardation with a small head circumference, facial dysmorphisms, and low cholesterol levels. UBE3B encodes an uncharacterized E3 ubiquitin ligase. The identified UBE3B variants include one frameshift and two splice-site mutations as well as a missense substitution affecting the highly conserved HECT domain. Disruption of mouse Ube3b leads to reduced viability and recapitulates key aspects of the human disorder, such as reduced weight and brain size and a downregulation of cholesterol synthesis. We establish that the probable Caenorhabditis elegans ortholog of UBE3B, oxi-1, functions in the ubiquitin/proteasome system in vivo and is especially required under oxidative stress conditions. Our data reveal the pleiotropic effects of UBE3B deficiency and reinforce the physiological importance of ubiquitination in neuronal development and function in mammals.

All ptosis procedures were performed using the Gore-Tex MVP sheet. The implant was normally 7 mm wide for adults and 5 mm wide for children. The implantation method was the same as that used for the sheet shape fascia.Results: In all patients, satisfactory functional results were observed at the 6-month follow-up examination. Eyelid opening heights were also obtained. The average marginal reflex distance (MRD was -0.5 mm preoperatively, which improved to +1.9 mm after surgery. After one year, average MRD was +1.6 mm. MRD attenuation was more frequent in the younger group. There were no cases requiring redo surgery and only one case of exposure.Keywords: polytetrafluoroethylene, Gore-Tex®, frontalis suspension, congenital ptosis, recurrence

    A nasal anemometer is a useful tool for speech therapists in their assessment of treatment effectiveness. This work is the second part of a research scheme which describes how the system is compatible with the use of an IBM PC-AT microcomputer using a suitable analogue-to-digital convertor. This enables the system to perform signal processing and to display, draw, and calculate a numerical 'figure of merit' using Kendall's tau nonparametric correlation.

  1. Does Post Septoplasty Nasal Packing Reduce Complications?

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not.Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

    This is the first report describing the use and pharmacological characterization of nasal patency by both pressure rhinometry and acoustic rhinometry (AcR) in an experimental cat model of nasal congestion. In pressure rhinometry studies, aerosolized compound 48/80 (0.1-3.0%), a mast cell liberator...... histamine (0.1-1.0%) on nasal geometry were similar to compound 48/80. We conclude that the cat is a useful model for evaluating the pharmacological actions of potential nasal decongestants.

    Full Text Available Nasal intubation technique was first described in 1902 by Kuhn. The others pioneering the nasal intubation techniques were Macewen, Rosenberg, Meltzer and Auer, and Elsberg. It is the most common method used for giving anesthesia in oral surgeries as it provides a good field for surgeons to operate. The anatomy behind nasal intubation is necessary to know as it gives an idea about the pathway of the endotracheal tube and complications encountered during nasotracheal intubation. Various techniques can be used to intubate the patient by nasal route and all of them have their own associated complications which are discussed in this article. Various complications may arise while doing nasotracheal intubation but a thorough knowledge of the anatomy and physics behind the procedure can help reduce such complications and manage appropriately. It is important for an anesthesiologist to be well versed with the basics of nasotracheal intubation and advances in the techniques. A thorough knowledge of the anatomy and the advent of newer devices have abolished the negative effect of blindness of the procedure.

Patient history and assessment of nasal symptoms are essential components of diagnosis, providing an initial evaluation that may be adequate to rule out serious conditions. However, current congestion medications are not always fully effective. Thus, if symptoms do not respond adequately to therapy, or symptoms suggestive of more serious conditions are present, specialized assessments may be needed. Various techniques are available for diagnosing patients, including those used chiefly by primary care clinicians and those requiring the expertise of otolaryngologists, allergists, and other specialists. Endoscopy remains a mainstay for evaluating nasal blockage and its causes, while modalities such as peak nasal inspiratory flow and acoustic rhinometry are evolving to provide easy-to-use, noninvasive procedures that are sensitive enough to measure small but clinically important abnormalities and therapeutic changes. Several imaging modalities are available to the specialist for severe or unusual cases, as are specialized diagnostic procedures that measure adjunctive features of congestion, such as impaired mucociliary function.Keywords: allergic rhinitis, congestion, diagnosis, obstruction, rhinosinusitis

    Full Text Available Introduction: Schwannomas are benign tumors that arise from Schwann cells peripheral nerves sheath. About 25-45% occur in the head and neck and only 4% of these tumors involve the sinunasal tract.Objective: To provide, through a clinic case and lecture review, the clinical and radiopatology findings of a bening and unusual tumors, as are the Nasal schwannomas. Case Report: We report a case of a young woman with nasal schwannoma, who complain of left nasal obstruction and rhinorrhea, which after subsequent imaging studies, surgical and pathology analisis, diagnosis was found. Sustained a favorable clinical evolution.Results and Discussion: The clinic and radiologic findings are nonspecific, depend upon the location or size of the tumor and subsequent involvement of surrounding structures, but generally present as a mass with less agressive behavior. The elective treatment is surgery, confirming this disease by microscopic and immunohistochemistry studies.Conclusion: Given these aspects must be considered nasal schwannomas within the differential diagnosis of a tumor with less aggressive behavior, clinical-radiological, because implies good results for the patient and unusual recurrence after surgery.

    Full Text Available Nasal glomangiopericytoma is rare. The immunophenotype is heterogeneous, more frequently smooth-muscle-actin and CD34-positive. We report expression patterns for several vascular-related proteins such as CD99, CD146, Bcl2, and WT1 as well as for treatment-related proteins such as mTOR and EGFR in a nasal glomangiopericytoma. The patient (woman, 86 years presented with a left nasal tumefaction. The resected specimen (1.5-cm showed a glomangiopericytoma. Tumor cells expressed smooth-muscle-actin, CD31, CD34, and progesterone receptor. They also expressed the vascular-cell-related proteins Bcl2, CD99, CD146, and WT1, as well as mTOR and EGFR. Nasal glomangiopericytomas show immunohistochemical heterogeneity for vascular-related markers, suggesting a possible extensive pericytic differentiation. The expression of potential targets for drug treatments such as mTOR and EGFR may impact on the clinical follow-up of these tumors occurring at advanced ages, which may require complex surgery.

    Full Text Available A 23-year-old lady presented with a slowly progressing firm mass on the nasal dorsum since 8 months. Her biochemical, haematological and collagen vascular disease screening tests were normal. Radiographs of the nasal bones showed a subcutaneous calcifying lesion with no evidence of nasal bone erosion. A diagnosis of idiopathic calcinosis cutis (ICC was made. The mass was excised and soft tissue defect was augmented with silicone prosthesis. The histopathology with the haematoxylin and eosin staining and von Kossa stain confirmed the diagnosis of calcinosis cutis. This is an unusual presentation of ICC involving the nasal dorsum requiring surgery and nasal dorsal augmentation with silicone prosthesis.

    Phonology is traditionally seen as the discipline that concerns itself with the building blocks of linguistic messages. It is the study of the structure of sound inventories of languages and of the participation of sounds in rules or processes. Phonetics, in contrast, concerns speech sounds as produced and perceived. Two extreme positions on the relationship between phonological messages and phonetic realizations are represented in the literature. One holds that the primary home for linguistic symbols, including phonological ones, is the human mind, itself housed in the human brain. The second holds that their primary home is the human vocal tract.

    Full Text Available Background: Transverse nasal groove is a condition of cosmetic concern which awaits due recognition and has been widely described as a shallow groove that extends transversely over the dorsum of nose. However, we observed variations in the clinical presentations of this entity, hitherto undescribed in literature. Aims: We conducted a clinicoepidemiological study of transverse nasal lesions in patients attending our outpatient department. Methods: We conducted a prospective observational study. We screened all patients attending our out-patient department for presence of transverse nasal lesions, signs of any dermatosis and associated other skin conditions. Results: One hundred patients were recruited in the study. Females (80% predominated over males. Most patients were of 15-45 years age group (70%. Majority of the transverse nasal lesions were classical transverse nasal groove (39% and others included transverse nasal line (28%, strip (28%, ridge (4% and loop (1%. Seborrhoeic diathesis was the most common condition associated with transverse nasal lesion. Conclusions: Occurrence of transverse nasal line, strip, ridge and loop, in addition to classical transverse nasal groove implies that latter is actually a subset of transverse nasal lesions. Common association of this entity with seborrheic dermatitis, seborrhea and dandruff raises a possibility of whether transverse nasal lesion is a manifestation of seborrheic diathesis.

  14. Three novel FOXL2 gene mutations in Chinese patients with blepharophimosis-ptosis-epicanthus inversus syndrome

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES, OMIM # 110100) is a rare autosomal dominant disorder affecting the eyelid and ovarian development. When co-occurred together, it is type I and when only the eyelid abnormalities are present, it is type II. Both types had been mapped to the same locus 3q23 on the basis of cytogenetic rearrangements 1-3 and linkage analyses. 4-6 Subsequently, haploinsufficiency of the FOXL2 gene (OMIM# 605597) was identified as the cause for both types. 7 This FOXL2 gene is a small gene consisting of a single exon of 2.7 kb. It belongs to the family of winged helix/forkhead transcription factors. The predicted protein of 376 amino acids contains the characteristic 100 amino acids (from amino acid position 52 to 152) DNA binding forkhead domain. Downstream of the forkhead is an alanine rich domain, consisting of 14 alanines (from amino acid position 221 to 234). This protein has been shown to express in the developing mouse eyelids, in both the fetal and adult ovarian follicular and stromal cells. 7, 8 Since the identification of the gene, increasing number of mutations are being described. Recently, a database (http://medgen.ugent.be/foxl2/) has been created to facilitate tracking of all the known FOXL2 intragenic mutations and variants. 9 Whether it is type I or II BPES depends on the FOXL2 genotype plus other unknown mechanism because for the same genotype, there is inter and intra-familial phenotypic variability.10 Furthermore, FOXL2 mutation might be associated with non-syndromic premature ovarian failure. In this work, we screened for FOXL2 mutations in our Chinese patients using multiplex ligation-dependent probe amplification (MLPA) and direct sequencing techniques.

  16. Associations between speech features and phenotypic severity in Treacher Collins syndrome

    Science.gov (United States)

    2014-01-01

    Background Treacher Collins syndrome (TCS, OMIM 154500) is a rare congenital disorder of craniofacial development. Characteristic hypoplastic malformations of the ears, zygomatic arch, mandible and pharynx have been described in detail. However, reports on the impact of these malformations on speech are few. Exploring speech features and investigating if speech function is related to phenotypic severity are essential for optimizing follow-up and treatment. Methods Articulation, nasal resonance, voice and intelligibility were examined in 19 individuals (5–74 years, median 34 years) divided into three groups comprising children 5–10 years (n = 4), adolescents 11–18 years (n = 4) and adults 29 years and older (n = 11). A speech composite score (0–6) was calculated to reflect the variability of speech deviations. TCS severity scores of phenotypic expression and total scores of Nordic Orofacial Test-Screening (NOT-S) measuring orofacial dysfunction were used in analyses of correlation with speech characteristics (speech composite scores). Results Children and adolescents presented with significantly higher speech composite scores (median 4, range 1–6) than adults (median 1, range 0–5). Nearly all children and adolescents (6/8) displayed speech deviations of articulation, nasal resonance and voice, while only three adults were identified with multiple speech aberrations. The variability of speech dysfunction in TCS was exhibited by individual combinations of speech deviations in 13/19 participants. The speech composite scores correlated with TCS severity scores and NOT-S total scores. Speech composite scores higher than 4 were associated with cleft palate. The percent of intelligible words in connected speech was significantly lower in children and adolescents (median 77%, range 31–99) than in adults (98%, range 93–100). Intelligibility of speech among the children was markedly inconsistent and clearly affecting the understandability

  18. Smart polymers in nasal drug delivery

    Directory of Open Access Journals (Sweden)

    Ankita Chonkar

    2015-01-01

    Full Text Available Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from the nose before complete absorption through nasal mucosa. Therefore, mucoadhesive polymeric approach can be successfully used to enhance the retention of the drug on nasal mucosal surface. Here, some of the aspects of the stimuli responsive polymers have been discussed which possess liquid state at the room temperature and in response to nasal temperature, pH and ions present in mucous, can undergo in situ gelation in nasal cavity. In this review, several temperature responsive, pH responsive and ion responsive polymers used in nasal delivery, their gelling mechanisms have been discussed. Smart polymers not only able to enhance the retention of the drug in nasal cavity but also provide controlled release, ease of administration, enhanced permeation of the drug and protection of the drug from mucosal enzymes. Thus smart polymeric approach can be effectively used for nasal delivery of peptide drugs, central nervous system dugs and hormones.

    Objectives : (1) To compare oral pressure and nasal airflow in 3- to 5-year-olds versus older children and adults; (2) to describe stability of these measures in 3- to 5-year-olds at two recording times; and (3) to report participation rates of 3- to 5-year-olds for the aerodynamic protocol. Design : Prospective, nonrandomized, convenience samples in four age groups. Setting : University clinic. Participants : A total of 105 individuals without cleft palate and with normal speech for their age who were 3 to 5 (n  =  45), 7 to 9 (n  =  20), 11 to 13 (n  =  20), or 20 to 30 years old (n  =  20). All had normal nasal resonance and absence of nasally obstructive conditions on the testing day. Main Outcome Measures : Oral pressure and nasal airflow on /p/ and /m/ in syllable series and the word "hamper." Results : Oral pressure was significantly higher on /p/ for 3- to 5-year-olds versus the two oldest groups. Nasal airflow on /p/ occurred infrequently across groups. Oral pressure on /m/ was significantly higher for 3- to 5-year-olds versus adults. Nasal airflow on /m/ increased significantly with age. Oral pressure and nasal flow did not differ at two measurement times for the 3- to 5-year-olds. Of the 3- to 5-year-olds, 88% completed the protocol. Conclusions : Oral pressure decreased on /p/ and nasal airflow increased on /m/ from early childhood into adulthood. Nasal air escape on /p/ occurred rarely for speakers of any age; when it did occur, the magnitude was limited. Most preschool-aged children should be able to complete a velopharyngeal aerodynamic protocol, and measures are stable even for these young speakers.

    Full Text Available Objective. Short-term nasal forms following primary lip repair were compared between presurgical nasal molding and control groups. Aim. To compare nasal symmetry between patients that had nasal molding and lip repair with those that had only lip repair. Design. Retrospective case-control study Patients. Complete unilateral CL+P patients had basilar and frontal photographs at two time points: (1 initial (2 postsurgical. 28 nasal molding patients and 14 control patients were included. Intervention. Presurgical nasal molding was performed prior to primary lip repair in intervention group. No nasal molding was performed in control group. Hypothesis. Nasal molding combined with lip surgery repair according to the Millard procedure provides superior nasal symmetry than surgery alone for nostril height-width ratios and alar groove ratios. Statistics. Shapiro-Wilk test of normality and Student’s -tests. Results. A statistically significant difference was found for postsurgical nostril height-width ratio (<.05. No other statistically significant differences were found. Conclusions. Nasal molding and surgery resulted in more symmetrical nostril height-width ratios than surgery alone. Alar groove ratios were not statistically significantly different between groups perhaps because application of nasal molding was not early enough; postsurgical nasal splints were not utilized; overcorrection was not performed for nasal molding.

    Rehabilitation of speech is tantamount to closure of defect in cases with velopharyngeal insufficiency. Often the importance of speech therapy is sidelined during the fabrication of obturators. Usually the speech part is taken up only at a later stage and is relegated entirely to a speech therapist without the active involvement of the prosthodontist. The article suggests a protocol for speech therapy in such cases to be done in unison with a prosthodontist.

    Full Text Available Among all the possible complications of aesthetic rhinoplasty, a rare one is the development of cystic masses on the nasal dorsum: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients had undergone aesthetic rhinoplasty in the past (26 years ago and 14 years ago, resp.. Both cystic masses were removed via a direct open approach and nasal reconstruction was performed successfully with autologous vomer bone. The pathologic investigations showed a foreign body inclusion cyst associated with latex rubber in the first case and a sequestration of a mucosal-lined nasal bone was not removed at the time of primary rhinoplasty in the second case. A brief review of the literature focuses on the pathophysiology and treatment options for nasal dorsal cysts following aesthetic rhinoplasty.

    Various case reports on nasal myiasis written during the 1990s and 2000s state that nasal myiasis, which is known as peenash among South Asian natives, is a form of divine punishment in Hindu mythology, but do not provide citations from Hindu scriptures that would suggest this interpretation. This paper aims to discuss the phenomenon of peenash in a historical context by examining medical literature written during the nineteenth and early twentieth centuries, to identify Hindu texts contributing to the belief of some Hindus that nasal myiasis is a form of divine punishment, and to provide an overview of contemporary treatment for and management of nasal myiasis.

    The purpose of this study was to identify and compare the temporal characteristics of nasalization in relation to (1) languages, (2) vowel contexts, and (3) age groups. Two distinct acoustic energies from the mouth and nose were recorded during speech production (/pamap, pimip, pumup/) using two microphones to obtain the absolute and proportional measurements on the acoustic temporal characteristics of nasalization. Twenty-eight normal adults (14 American English and 14 Korean speakers) and 28 normal children (14 American English and 14 Korean speakers) participated in this study. In both languages, adults showed shorter duration of nasalization than children within all three vowel contexts. The high vowel context revealed longer duration of nasalization than the low vowel context in both languages. There was no significant difference of temporal characteristics of nasalization between American English and Korean. Nasalization showed different timing characteristics between children and adults across vowel contexts. The results are discussed in association with developmental coarticulation and the relationship between acoustic consequences of articulatory events and vowel height.

    Nasal airway obstruction (NAO) is a common health problem with 340,000 patients undergoing surgery annually in the United States. Traditionally, otolaryngologists have focused on airspace cross-sectional areas and nasal resistance to airflow as objective measures of nasal patency, but neither of these variables correlated consistently with patients' symptoms. Given that the sensation of nasal airflow is also associated with mucosal cooling (i.e., heat loss) during inspiration, we investigated the correlation between the sensation of nasal obstruction and mucosal cooling in 10 patients before and after NAO surgery. Three-dimensional models of the nasal anatomy were created based on pre- and post-surgery computed tomography scans. Computational fluid dynamics (CFD) simulations were conducted to quantify nasal resistance and mucosal cooling. Patient-reported symptoms were measured by a visual analog scale and the Nasal Obstruction Symptom Evaluation (NOSE), a disease-specific quality of life questionnaire. Our results revealed that the subjective sensation of nasal obstruction correlated with both nasal resistance and heat loss, but the strongest correlation was between the NOSE score and the nasal surface area where heat flux exceeds 50 W /m2 . In conclusion, a significant post-operative increase in mucosal cooling correlates well with patients' perception of better nasal patency after NAO surgery.

    The velopharyngoplasty performed using the popular Sanvenero-Rosselli method improves the speech quality of patients with cleft palate suffering from persistent velopharyngeal insufficiency despite successful closure of the hard and soft palates. However, often a relatively narrow pharyngeal bridge results due to healing not only by granulation and scar contraction, but also due to the insertion of the inferior tip of the flap into a narrow bed. Elevation of two velar flaps with nasal mucosa to cover the exposed muscular undersurface of the pharyngeal flap produces a broader recipient bed into which the pharyngeal flap can be spread. The speech quality of 27 patients treated with this modified method (group B) was compared with that of 27 patients without this modification (group A). Eight weeks after velopharyngoplasty (followed by uneventful wound healing) the speech quality of group B was significantly better than that of group A (pvelum is an important modification of velopharyngoplasty for the improvement of speech quality.

    Numbered nasal discs were successfully used in studies requiring large numbers of individually marked waterfowl. The procedure for constructing these discs is outlined. Blue-winged teal (Anas discors) with 5/8-inch discs, and canvasback (Aythya valisineria) and redhead (A. americana) with 3/4-inch discs can be individually identified up to 50 and 80 yards, respectively, with a gunstock-mounted, 20-power spotting scope. The particular value of these markers is their durability, the number of combinations possible, and the apparent absence of behavioral or mortality influence among such species as the blue-winged teal.

    Objectives The current study aims to summarize breast anthropomorphic measurement features in Chinese patients with breast diseases and to investigate their potential correlations with demographic factors. Materials and methods Fifteen breast anthropomorphic parameters of 605 Chinese female patients were collected prospectively. Breast ptosis status was scaled by two methods and breast volume was calculated according to a modified formula of BREAST-V. Results Among 1210 breasts, the average breast volume was 340.0±109.1 ml (91.8–919.2 ml). The distance from the nipple to the inframammary fold was 7.5±1.6 cm in the standing position. The width of the breast base was 14.3±1.4 cm (8.5–23.5 cm). The incidence of breast ptosis was 22.8% (274/1204), of which 37 (23.5%) and 79 (31.7%) women had severe ptosis assessed by different criteria. Increased height (OR[odds ratio] = 1.500, Pcosmetic and reconstructive breast surgery decisions. Post-menopausal status, increased BMI, and breastfeeding for more than six months were independent risk factors for both increased breast volume and breast ptosis. PMID:28192525

    Full Text Available Background: The nasal index determination is one of the most commonly used anthropometric parameters in classifying human races. There are few reports in medical literature concerning nasal index that specifically address particular Egyptian populations. The objective of this study was to determine the normal parameters of external nose (width, height and nasal index in Egyptians. Methods: The study was conducted randomly on healthy Egyptian subjects of both sexes. Nasal height and width were measured using vernier caliper. Then, nasal index was determined for each subject. The obtained data were subjected to statistical analysis. Results: A total of 290 subjects, 144 males and 146 females, aged 1 month– 65 years, were enrolled in the study. The study showed the existence of sexual dimorphism in nasal morphology, appearing after the age 20 years. The mean nasal index in the investigated adults was 68.01; in males and females was 71.46 and 64.56, respectively. Conclusions: The dominant nasal type in Egyptians was in-between mesorrhine "medium" and leptorrhine "narrow" nose. Forensic and anthropological research, as well as cosmetic and reconstructive surgery may benefit from age- and sex- based data of the study.

    Full Text Available Introduction: Rhinoscleroma, a rare nasal granulomatous disease, is caused by Klebsiella rhinoscleromatis. The nose is the primary occurrence region. Nasal non-Hodgkin lymphoma is a rare cancer, and could be of T or B type. The rhinoscleroma and the nasal non-Hodgkin lymphoma present with nasal obstruction as the main symptom, and are part of the nasal granulomatosis differential diagnosis. Objective: To report the association of rhinoscleroma and non-Hodgkin lymphoma in the same patient, by remarking the importance of the nasal granulomatosis' differential diagnosis. Case Report: A forty-nine year old female patient that appeared with a one-month progressive nasal obstruction. Rhinoscopy showed papillomatous feature lesion in left middle meatus. The immunohistochemical analysis confirmed rhinoscleroma. The patient was duly treated with total remission of the lesion. Ten months after, she returned with the same symptoms, but the histologic study confirmed non-Hodgkin lymphoma. Final Comments: Both pathologies may cause more severe nasal symptoms and complications. The early diagnostic enables the choice for the right treatment and contributes for the prognosis. The immunohistochemical study was essential for the diagnostic differentiation.

    Provide a descriptive analysis of children admitted to a tertiary care pediatric emergency department (PED) for a nasal foreign body (NFB) and describe the current knowledge and management of such accidents. A retrospective study was conducted from January 2003 to May 2008, including all patients aged less than 15 years admitted for a NFB. The data collected were age, sex, geographic origin, time and day of admission, duration in PED, duration of NFB insertion, nostril location, symptoms and clinical signs, prehospital extraction attempts, facial x-ray, extraction mode, referral to an ENT specialist, progression, and complications. For statistical analysis, the data were entered in Microsoft Excel spreadsheets. The data were analyzed with StatView 5.1 (SAS Institute) and EpiInfo 6.04fr (VF, ENSP Epiconcept). In the descriptive analysis, the data are presented as mean values with standard deviation, median with extreme values or with 95% confidence intervals where appropriate, unless otherwise indicated. To compare qualitative variables, a chi(2) test (Mantel-Haenszel) was used and the two-tailed Fisher exact test if the expected value was 5 or less. Statistical significance was set at pChildren aged less than 4 years accounted for 71% of the studied population. The mean age was 3.5+/-1.6 years (range, 1.4-13 years). The majority of accidents occurred at home (95%). The length of time spent in the PED was 78+/-57 min. The NFB duration of insertion was unknown in one-quarter of cases, present for less than 4 h in 65% of cases. No symptoms were described in most cases (88%). When symptoms were described, bleeding, pain or nasal discomfort, and foul nasal odor were the principal symptoms. The right nostril was the predominant location (60%). This difference tended to disappear in the group of children aged less than 4 years. Five children had bilateral NFB. Nonorganic compounds accounted for 80% of the NFB: plastic beads or balls (39%), plastic or toy parts (20

    Holocephalans (chimaeras) are a group of marine fishes comprising three families: the Callorhinchidae (callorhinchid fishes), the Rhinochimaeridae (rhinochimaerid fishes) and the Chimaeridae (chimaerid fishes). We have used X-ray microcomputed tomography and magnetic resonance imaging to characterise in detail the nasal anatomy of three species of chimaerid fishes: Chimaera monstrosa, C. phantasma and Hydrolagus colliei. We have shown that the nasal chamber of these three species is linked to the external environment by an incurrent channel and to the oral cavity by an excurrent channel via an oral groove. A protrusion of variable morphology is present on the medial wall of the incurrent channel in all three species, but is absent in members of the two other holocephalan families that we inspected. A third nasal channel, the lateral channel, functionally connects the incurrent nostril to the oral cavity, by-passing the nasal chamber. From anatomical reconstructions, we have proposed a model for the circulation of water, and therefore the transport of odorant, in the chimaerid nasal region. In this model, water could flow through the nasal region via the nasal chamber or the lateral channel. In either case, the direction of flow could be reversed. Circulation through the entire nasal region is likely to be driven primarily by the respiratory pump. We have identified several anatomical features that may segregate, distribute, facilitate and regulate flow in the nasal region and have considered the consequences of flow reversal. The non-sensory cilia lining the olfactory sensory channels appear to be mucus-propelling, suggesting that these cilia have a common protective role in cartilaginous fishes (sharks, rays and chimaeras). The nasal region of chimaerid fishes shows at least two adaptations to a benthic lifestyle, and suggests good olfactory sensitivity, with secondary folding enhancing the hypothetical flat sensory surface area by up to 70%.

    Full Text Available It has recently been shown that vascular endothelial growth factor (VEGF enhances vascular permeability and that mast cells produce VEGF, suggesting the involvement of VEGF in allergic diseases. In the present study we quantitatively analyzed VEGF in the nasal lavage fluid of patients with nasal allergy. We performed nasal antigen challenge with Japanese cedar pollen antigen in 10 healthy adult volunteers and in 10 cedar pollen IgE-positive patients with nasal allergy. In all patients with nasal allergy, VEGF and histamine levels in the nasal lavage fluid reached a peak 30 min after antigen challenge, then returned to prechallenge values 2 h after antigen challenge. In these patients, the histamine level increased three-fold, while the VEGF level increased 10-fold. However, in all healthy adult volunteers, VEGF and histamine levels did not increase. A stronger correlation was noted between the ratio of decreased nasal cavity volume and the ratio of increased VEGF levels (R = 0.823; P < 0.001 than between the ratio of nasal cavity volume and the ratio of increased histamine levels (R = 0.660; P < 0.01. These results suggest that VEGF may contribute to the pathogenesis of nasal obstruction in the early phase of nasal allergy as a new factor involved in increasing vascular permeability.

    Facial paralysis resulting from leprosy has a serious impact on the entire face especially in the areas innervated by the facial nerves. In particular, lagophthalmos in patients with leprosy causes exposure keratitis, corneal, and conjunctival dryness, which can progress to blindness and disfigurement. Recently, we conducted 4 different temporalis muscle transfer (TMT) methods over the last 4 years to reduce ptosis. The methods used included Brown-McDowell, McCord-Codner, modified Gillies-Anderson, and modified Gillies. Seventy-five TMT operations in 60 patients were performed between 2011 and 2014. The mean age was 70.1. Fifteen patients had bilateral TMT procedures. As a result, ptosis appeared in 14(18.7%) of 75 TMT procedures for 4 years. To prevent or correct this complication, the following 4 technical refinements have simplified the surgery and yield better surgical outcomes. First, an increase in the length of the temporalis muscle flap to approximately 8 cm with a parallel course to the lateral canthus will reduce oblique pull. Second, the width of the fascia sling in the upper eyelid is narrowed (3-4 mm) to reduce weight on the eyelid. Third, the fascia sling in the upper lid should not be located along the full length of the upper lid but terminate 3.5 cm medial to lateral canthal tendon and in other words, should not be tied at the medial canthal tendon to reduce tension and weight. Lastly, the fascia sling in the eyelid should be located shallow (probably in subdermal layer) and as near as possible to the lid margin to prevent any functional disturbance in levator aponeurosis.

    2013-12-01

    Spinocerebellar ataxias (SCAs) are a heterogeneous group of autosomal dominant cerebellar ataxias clinically characterized by progressive ataxia, dysarthria and a range of other concomitant neurological symptoms. Only a few studies include detailed characterization of speech symptoms in SCA. Speech symptoms in SCA resemble ataxic dysarthria but symptoms related to phonation may be more prominent. One study to date has shown an association between differences in speech and voice symptoms related to genotype. More studies of speech and voice phenotypes are motivated, to possibly aid in clinical diagnosis. In addition, instrumental speech analysis has been demonstrated to be a reliable measure that may be used to monitor disease progression or therapy outcomes in possible future pharmacological treatments. Intervention by speech and language pathologists should go beyond assessment. Clinical guidelines for management of speech, communication and swallowing need to be developed for individuals with progressive cerebellar ataxia.

    Chronic rhinosinusitis with nasal polyposis (NP) represents an invalidating disorder that causes mainly nasal blockage and loss of smell. The aim of this study is to investigate correlations between individual subjective and objective parameters of stable NP disease. 65 NP patients scored their sinonasal symptoms on a visual analogue scale (VAS) and questionnaires (SNOT-22 and SF-36). Peak nasal inspiratory flow (PNIF) measurement, Sniffinatm Sticks (SS) smell test, blood analysis for eosinophilia, total IgE and culture for Staphylococcus aureus (SA) were performed. VAS scores for nasal blockage correlated with the SNOT-22 and SF-36 scores, which was not observed for VAS of other symptoms. VAS scores for nasal blockage correlated well with PNIF values as well as VAS scores for smell dysfunction and SS results (both psmell reduction (psmell reduction in NP disease. Nasal blockage is the only symptom that correlates well with NP size and SNOT-22 scores, whereas smell reduction correlates with blood eosinophilia.

    A friction force is generated when moving air contacts the nasal walls, referred to as wall shear stress. This interaction facilitates heat and mass transfer between the mucosa and air, i.e., air-conditioning. The objective of this research was to study the distribution of wall shear stress within the nasal cavity to identify areas that contribute significantly to air-conditioning within the nasal cavity. Three-dimensional computational models of the nasal airways of five healthy subjects (three male and two female subjects) were constructed from nasal CT scans. Numerical simulations of nasal airflow were conducted using the commercial computational fluid dynamics code Fluent 6 (Ansys, Inc., Canonsburg, PA). Wall shear stress was derived from the numerical simulation. Air-conditioning was simulated to confirm the relationship with wall shear stress. Nasal airflow simulations predicted high wall shear stress along the anterior aspect of the inferior turbinate, the anteroinferior aspect of the middle turbinate, and within Little's area. The airflow simulations indicate that the inferior and middle turbinates and Little's area on the anterior nasal septum contribute significantly to nasal air-conditioning. The concentration of wall shear stress within Little's area indicates a desiccating and potentially traumatic effect of inhaled air that may explain the predilection for spontaneous epistaxis at this site.

    Nasal geometries and temperature of the nasal mucosa are the primary factors affecting nasal air conditioning. Data on intranasal air conditioning after provoking the trigeminal nerve with a cold stimulus simulating the effects of an arctic condition is still missing. The objective was to investigate the influence of skin cooling face masks on nasal air conditioning, mucosal temperature and nasal geometry. Standardized in vivo measurements of intranasal air temperature, humidity and mucosal temperature were performed in 55 healthy subjects at defined detection sites before and after wearing a cooling face mask. Measurements of skin temperature, rhinomanometry and acoustic rhinometry were accomplished. After wearing the face mask the facial skin temperature was significantly reduced. Intranasal air temperature did not change. Absolute humidity and mucosal temperature increased significantly. The acoustic rhinometric results showed a significant increase of the volumes and the cross-sectional areas. There was no change in nasal airflow. Nasal mucosal temperature, humidity of inhaled air, and volume of the anterior nose increased after application of a cold face mask. The response is mediated by the trigeminal nerve. Increased mucosal temperatures as well as changes in nasal geometries seem to guarantee sufficient steady intranasal nasal air conditioning.

  17. Perceiving nasal patency through mucosal cooling rather than air temperature or nasal resistance.

    Directory of Open Access Journals (Sweden)

    Kai Zhao

    Full Text Available Adequate perception of nasal airflow (i.e., nasal patency is an important consideration for patients with nasal sinus diseases. The perception of a lack of nasal patency becomes the primary symptom that drives these patients to seek medical treatment. However, clinical assessment of nasal patency remains a challenge because we lack objective measurements that correlate well with what patients perceive. The current study examined factors that may influence perceived patency, including air temperature, humidity, mucosal cooling, nasal resistance, and trigeminal sensitivity. Forty-four healthy subjects rated nasal patency while sampling air from three facial exposure boxes that were ventilated with untreated room air, cold air, and dry air, respectively. In all conditions, air temperature and relative humidity inside each box were recorded with sensors connected to a computer. Nasal resistance and minimum airway cross-sectional area (MCA were measured using rhinomanometry and acoustic rhinometry, respectively. General trigeminal sensitivity was assessed through lateralization thresholds to butanol. No significant correlation was found between perceived patency and nasal resistance or MCA. In contrast, air temperature, humidity, and butanol threshold combined significantly contributed to the ratings of patency, with mucosal cooling (heat loss being the most heavily weighted predictor. Air humidity significantly influences perceived patency, suggesting that mucosal cooling rather than air temperature alone provides the trigeminal sensation that results in perception of patency. The dynamic cooling between the airstream and the mucosal wall may be quantified experimentally or computationally and could potentially lead to a new clinical evaluation tool.

    Full Text Available Abstract Background Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. Case presentation We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eighteen month old Nigerian female who presented with a history of noisy breathing associated with recurrent rhinorrhea since birth. Physical examination revealed obstruction of the right nasal cavity by a pale fleshy mass. She underwent a total surgical excision and to date, after thirty one months follow-up, she is free from recurrence. Conclusion The prognosis for benign teratoma of the nasal septum is good following total surgical excision.

    H1 antihistamines constitute one of the main references for the treatment of allergic rhinitis. Classically, these drugs have been considered effective in controlling sneezing, rhinorrhea and itching, though they have not been regarded as particularly effective in application to nasal obstruction. The most recent studies, involving second-generation H1 antihistamines (desloratadine, fexofenadine, levocetirizine, rupatadine), have shown these drugs to offer effects upon nasal obstruction significantly superior to those of placebo. The present review examines the effect of bilastine, a new, potent and highly specific H1 antihistamine without sedative effects or cardiac toxicity, upon nasal obstruction. The analysis of the data from the different clinical trials indicates that in patients with allergic rhinitis, the effect of bilastine upon nasal obstruction is superior to that of placebo and similar to that of other second-generation H1 antihistamines, manifesting within 24 hours after the start of treatment.

    Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

  4. Development of the cetacean nasal skull.

    The adaptation of cetaceans to aquatic life habits is reflected, in their nasal region, in three marked changes from the original relations found in land mammals. These changes include (1) the loss of the sense of smell, (2) translocation of the nostrils from the tip of the rostrum to the vertex of the head, and (3) elongation of the anterior head to form a rostrum protruding far towards anterior. The morphogenetic processes taking place during embryogenesis of the nasal skull play a decisive part in the development of all these changes. The lateral parts of the embryonic nasal capsule, encompassing the nasal passages, change their position from horizontal to vertical. At the same time, the structures of the original nasal floor (the solum nasi) are shifted in front of the nasal passages towards the rostrum. The structures of the original nasal roof (the tectum nasi) and of the nasal side wall (the paries nasi) are translocated behind the nasal passages towards the neurocranium. The medial nasal septum (the septum nasi) mostly loses its connection to the nasal passages and is produced into a point protruding far towards anterior. The transformed embryonic nasal skull of the Cetacea can be divided into three sections: 1. The median structures. These include the cartilaginous structures, viz., the rostrum nasi, the septum interorbitale and the spina mesethmoidalis, which are accompanied by the dermal bones, the vomer and the praemaxillare. In adult cetaceans the rostrum nasi is mostly preserved as a robust cartilage of the skull, which may possibly serve as a sound transmitting structure of the sonar system, or it may be responsible for the sensing of water streams and vibrations. 2. The posterior side wall structures. These include the following cartilaginous structures that are mostly heavily reduced or mutually fused: the cupula nasi anterior, the tectum nasi, the lamina cribrosa, the paries nasi, the commissura orbitonasalis, the cupula nasi posterior, the

    Full Text Available Abstract The possibility of producing local hyposensitization by administering allergens via mucosal routes was envisaged at the beginning of 1900, and local nasal immunotherapy has been extensively studied since the 1970s. Presently, there are 21 randomized controlled trials being conducted with the most common allergens, consistently showing the clinical efficacy of local nasal immunotherapy for rhinitis. Other advantages are that it has an optimal safety profile and can be self-administered at home by the patient. Moreover, there are several data from animal models and from humans that confirm the immunomodulatory effect of intranasally administered antigens. On the other hand, local nasal immunotherapy seems to be effective only on rhinitis symptoms and requires a particular technique of administration. For these reasons, its clinical use is progressively declining in favour of the sublingual route although nasal immunotherapy is validated in official documents and remains a viable alternative to injection.

    During the past 2 decades, tuberculosis--both pulmonary and extrapulmonary--has re-emerged as a major health problem worldwide. Nasal tuberculosis--either primary or secondary to pulmonary tuberculosis or facial lupus--is rare, but it should be considered in the differential diagnosis of nasal granulomas. We describe a case of primary nasal tuberculosis in an adult male who presented with a polypoid lesion in one nasal cavity. The diagnosis was based on histopathology and the patient's successful response to antituberculous drug treatment. Given the rising incidence of tuberculosis, it is prudent that otolaryngologists remain cognizant of this infection as a potential cause of unusual lesions in the head and neck.

  7. Numerical simulation and nasal air-conditioning

    2010-01-01

    Full Text Available Heating and humidification of the respiratory air are the main functions of the nasal airways in addition to cleansing and olfaction. Optimal nasal air conditioning is mandatory for an ideal pulmonary gas exchange in order to avoid desiccation and adhesion of the alveolar capillary bed. The complex three-dimensional anatomical structure of the nose makes it impossible to perform detailed in vivo studies on intranasal heating and humidification within the entire nasal airways applying various technical set-ups. The main problem of in vivo temperature and humidity measurements is a poor spatial and time resolution. Therefore, in vivo measurements are feasible only to a restricted extent, solely providing single temperature values as the complete nose is not entirely accessible. Therefore, data on the overall performance of the nose are only based on one single measurement within each nasal segment. In vivo measurements within the entire nose are not feasible. These serious technical issues concerning in vivo measurements led to a large number of numerical simulation projects in the last few years providing novel information about the complex functions of the nasal airways. In general, numerical simulations merely calculate predictions in a computational model, e.g. a realistic nose model, depending on the setting of the boundary conditions. Therefore, numerical simulations achieve only approximations of a possible real situation. The aim of this review is the synopsis of the technical expertise on the field of in vivo nasal air conditioning, the novel information of numerical simulations and the current state of knowledge on the influence of nasal and sinus surgery on nasal air conditioning.

    Articulation is the result of speech organs and it means clean, clear and distinct pronunciation of voices in words. A prospective study included 24 children between 5 and 15 years of age, of both sexes. All children were monolingual, Serbian being their native language. The quality of articulation was tested with Triage articulation test. Neither omission nor distortion of plosives was observed in any of them, whereas substitution of plosives occurred in 12% of patients. Omission of affricates was not observed in any of the subjects, but substitution and distortion occurred in 29%, and 76% of subjects, respectively. Omission of fricatives was found in 29% subjects, substitution in 52%, and distortion in 82% of subjects. Omission and distortion of nasals was not recorded in any of the subjects, and substitution occurred in 6% of children. Omission of laterals was observed in 6%, substitution in 46% and distortion in 52% of subjects with articulation disorders. Discussion and Articulation disorders were observed not only in children diagnosed with dyslalia but in those with dysphasia and stuttering as well. Children with speech disorders articulate vowels best, then nasals and plosives. Articulation of fricatives and laterals was found to be most severely deviated, including all three disorders, i.e. substitution, omission and distortion. Spasms of speech muscles and vegetative reactions were also observed in this study, but only in children with stuttering.

    Parkinson's disease (PD) is associated with neuropathological changes in olfactory and gastrointestinal tissues, and PD patients frequently suffer from hyposmia, hyposalivation, and dysphagia. Since hyposmia and gastrointestinal dysfunction are frequently premotor symptoms, it has been speculated that an external, for example microbial, agent could trigger the pathologic process in the corresponding organs, subsequently spreading to the central nervous system. We recently showed evidence for compositional differences between the fecal microbiota of PD patients and control subjects. In this study, our objective was to explore a possible connection between nasal and oral microbiota and PD. We compared the oral and nasal bacterial communities of PD patients (oral: n = 72, nasal: n = 69) and control subjects (oral: n = 76, nasal: n = 67) using a 16S rRNA gene amplicon sequencing approach. Oral and nasal microbiota differed markedly from each other, with no notable similarity within subjects. Oral microbiota of PD patients and control subjects had differences in beta diversity and abundances of individual bacterial taxa. An increase in the abundance of opportunistic oral pathogens was detected in males, both with and without PD. Our data did not reveal convincing differences between the nasal microbiota of control subjects and PD patients. The oral microbiome deserves additional research regarding its connection to PD and its biomarker potential. The higher abundance of oral pathogens in men underlines the importance of monitoring and promoting male dental health. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. Trans-oral endoscopic partial adenoidectomy does not worsen the speech after cleft palate repair

    Directory of Open Access Journals (Sweden)

    Mosaad Abdel-Aziz

    Full Text Available ABSTRACT INTRODUCTION: Adenoid hypertrophy may play a role in velopharyngeal closure especially in patients with palatal abnormality; adenoidectomy may lead to velopharyngeal insufficiency and hyper nasal speech. Patients with cleft palate even after repair should not undergo adenoidectomy unless absolutely needed, and in such situations, conservative or partial adenoidectomy is performed to avoid the occurrence of velopharyngeal insufficiency. Trans-oral endoscopic adenoidectomy enables the surgeon to inspect the velopharyngeal valve during the procedure. OBJECTIVE: The aim of this study was to assess the effect of transoral endoscopic partial adenoidectomy on the speech of children with repaired cleft palate. METHODS: Twenty children with repaired cleft palate underwent transoral endoscopic partial adenoidectomy to relieve their airway obstruction. The procedure was completely visualized with the use of a 70° 4 mm nasal endoscope; the upper part of the adenoid was removed using adenoid curette and St. Claire Thompson forceps, while the lower part was retained to maintain the velopharyngeal competence. Preoperative and postoperative evaluation of speech was performed, subjectively by auditory perceptual assessment, and objectively by nasometric assessment. RESULTS: Speech was not adversely affected after surgery. The difference between preoperative and postoperative auditory perceptual assessment and nasalance scores for nasal and oral sentences was insignificant (p = 0.231, 0.442, 0.118 respectively. CONCLUSIONS: Transoral endoscopic partial adenoidectomy is a safe method; it does not worsen the speech of repaired cleft palate patients. It enables the surgeon to strictly inspect the velopharyngeal valve during the procedure with better determination of the adenoidal part that may contribute in velopharyngeal closure.

    consonantal articulations by the simultaneous occurrence of an oral closure and a nasal airflow release. Airflow release through the nasal cavity appears to be the primary feature of nasal consonants, which facilitates coarticulatory processes such as place assimilation in pre-consonantal contexts (e.g. velarization before velar stops. The present study investigates the allophonic phonetic features of nasal + velar stop coarticulation in Spanish and Catalan. More specifically, we assessed the effects of speech rate, stress, morphological boundaries and the voicing and articulatory tension of the following stop. Electropalatographic analyses (WinEPG were conducted on 4 repetitions of several nasal + velar stop sequences produced by 3 speakers of Spanish and 3 speakers of Catalan. The results reveal the importance of the factors investigated, in particular the voicing and articulatory tension of the following vowel. It was also shown that a slow speech rate led to hyperarticulation and the consequent frequent loss of place assimilation present in faster speech styles. These findings and the presence of certain types of partial assimilation suggest that this type of coarticulation should be treated as a gradient rather than a categorical process.

  1. Feature extraction and models for speech: An overview

    Science.gov (United States)

    Schroeder, Manfred

    2002-11-01

    Modeling of speech has a long history, beginning with Count von Kempelens 1770 mechanical speaking machine. Even then human vowel production was seen as resulting from a source (the vocal chords) driving a physically separate resonator (the vocal tract). Homer Dudley's 1928 frequency-channel vocoder and many of its descendants are based on the same successful source-filter paradigm. For linguistic studies as well as practical applications in speech recognition, compression, and synthesis (see M. R. Schroeder, Computer Speech), the extant models require the (often difficult) extraction of numerous parameters such as the fundamental and formant frequencies and various linguistic distinctive features. Some of these difficulties were obviated by the introduction of linear predictive coding (LPC) in 1967 in which the filter part is an all-pole filter, reflecting the fact that for non-nasalized vowels the vocal tract is well approximated by an all-pole transfer function. In the now ubiquitous code-excited linear prediction (CELP), the source-part is replaced by a code book which (together with a perceptual error criterion) permits speech compression to very low bit rates at high speech quality for the Internet and cell phones.

    2009-12-01

    Full Text Available People with a defective velopharyngeal mechanism speak with abnormal nasal resonance (hypernasal speech. Voice analysis methods for hypernasality detection commonly use vowels and nasalized vowels. However to obtain a more general assessment of this abnormality it is necessary to analyze stops and fricatives. This study describes a method with high generalization capability for hypernasality detection analyzing unvoiced Spanish stop consonants. The importance of phoneme-by-phoneme analysis is shown, in contrast with whole word parametrization which includes irrelevant segments from the classification point of view. Parameters that correlate the imprints of Velopharyngeal Incompetence (VPI over voiceless stop consonants were used in the feature estimation stage. Classification was carried out using a Support Vector Machine (SVM, including the Rademacher complexity model with the aim of increasing the generalization capability. Performances of 95.2% and 92.7% were obtained in the processing and verification stages for a repeated cross-validation classifier evaluation.

    Background The symptoms of allergic rhinitis (AR) greatly affect the quality of life (QoL) in the patients with AR. The correlations of nasal response to leukotriene D4 (LTD4) and histamine nasal provocation with health related QoL in AR are not clear. Objective To evaluate the correlations of nasal response to LTD4 and histamine nasal challenge with QoL in AR. Methods Patients randomly underwent LTD4 and histamine nasal challenge tests, completed the rhinoconjunctivitis quality of life questionnaire (RQoLQ), and rating the symptom severity score (total symptom score 4, TSS4) in the previous week. The correlations between nasal challenge tests induced nasal responses and QoL in RQoLQ were analyzed. Results A total of 25 eligible AR patients enrolled and finished both LTD4 and histamine nasal challenge and completed the questionnaire of RQoLQ. Histamine nasal challenge induced sneezing, increased nasal resistant were correlated with most of the dimensions (general, practical, nasal, eye problems, and quality of sleep, p < 0.05), while LTD4 nasal challenge induced sneeze, increased nasal resistant only correlated with nasal and ocular problems. On the contrary, the severity of the sneeze assessed by TSS4, was not correlated with QoL, while the severity of rhinorrhea, congestion, and nasal pruritus were correlated with nasal and practical problems, and nasal congestion was also correlated with ocular problems (r = 0.60, p = 0.01). Conclusion LTD4 and histamine nasal challenge induced nasal responses were correlated with different clinical symptoms severity and QoL, which can be used as a good diagnosis and evaluation methods for the management of AR.

  8. Nasal meatus plasty: a contribution to plastic reconstruction of the nasal valve during midfacial degloving

    Directory of Open Access Journals (Sweden)

    Lorenz, Kai J.

    2014-05-01

    Full Text Available Midfacial degloving is a proven method for easily accessing the midface, the nasal pyramid, the maxillary and ethmoidal sinuses, the orbits, as well as the anterior skull base. Indications for this method of access mainly include tumour resections in the area of the midface, the septum, the maxillary sinus, the paranasal to the sphenoidal sinus as well as the clivus. In addition, this method of access allows for the exposure of the bony structures of the midface in the event of extensive fractures.In general, this method of access combines an incision in the oral vestibule and circular incisions in the nasal vestibule area in order to release the nasal pyramid.After removing the facial wall of the maxillary sinus, extensive exposure of the surgical site is possible.One disadvantage of this method of access is the difficult reconstruction of the nasal valve area, which often leads to cicatricial stenoses and difficulties with breathing through the nose. Furthermore, wound healing problems and osteoradionecrosis in the area of the lateral margin of the anterior nasal aperture after replantation of the facial wall of the maxillary sinus have been described, because in this area sufficient soft tissue coverage cannot be ensured when a conventional technique is used.We describe a soft tissue flap pedicled in the cranial and caudal directions in the nasal valve area which makes both the reconstruction of the nasal vestibule and sufficient soft tissue coverage of the anterior nasal aperture possible.

  11. Triclosan promotes Staphylococcus aureus nasal colonization.

    Syed, Adnan K; Ghosh, Sudeshna; Love, Nancy G; Boles, Blaise R

    2014-04-08

    The biocide triclosan is used in many personal care products, including toothpastes, soaps, clothing, and medical equipment. Consequently, it is present as a contaminant in the environment and has been detected in some human fluids, including serum, urine, and milk. Staphylococcus aureus is an opportunistic pathogen that colonizes the noses and throats of approximately 30% of the population. Colonization with S. aureus is known to be a risk factor for several types of infection. Here we demonstrate that triclosan is commonly found in the nasal secretions of healthy adults and the presence of triclosan trends positively with nasal colonization by S. aureus. We demonstrate that triclosan can promote the binding of S. aureus to host proteins such as collagen, fibronectin, and keratin, as well as inanimate surfaces such as plastic and glass. Lastly, triclosan-exposed rats are more susceptible to nasal colonization with S. aureus. These data reveal a novel factor that influences the ability of S. aureus to bind surfaces and alters S. aureus nasal colonization. IMPORTANCE Triclosan has been used as a biocide for over 40 years, but the broader effects that it has on the human microbiome have not been investigated. We demonstrate that triclosan is present in nasal secretions of a large portion of a test population and its presence correlates with Staphylococcus aureus nasal colonization. Triclosan also promotes the binding of S. aureus to human proteins and increases the susceptibility of rats to nasal colonization by S. aureus. These findings are significant because S. aureus colonization is a known risk factor for the development of several types of infections. Our data demonstrate the unintended consequences of unregulated triclosan use and contribute to the growing body of research demonstrating inadvertent effects of triclosan on the environment and human health.

    Full Text Available Problem statement: In speech communication, speech coding aims at preserving the speech quality with lower coding bitrate. When considering the communication environment, various types of noises deteriorates the speech quality. The expressive speech with different speaking styles may cause different speech quality with the same coding method. Approach: This research proposed a study of speech compression for noise-corrupted Thai expressive speech by using two coding methods of CS-ACELP and MP-CELP. The speech material included a hundredmale speech utterances and a hundred female speech utterances. Four speaking styles included enjoyable, sad, angry and reading styles. Five sentences of Thai speech were chosen. Three types of noises were included (train, car and air conditioner. Five levels of each type of noise were varied from 0-20 dB. The subjective test of mean opinion score was exploited in the evaluation process. Results: The experimental results showed that CS-ACELP gave the better speech quality than that of MP-CELP at all three bitrates of 6000, 8600-12600 bps. When considering the levels of noise, the 20-dB noise gave the best speech quality, while 0-dB noise gave the worst speech quality. When considering the speech gender, female speech gave the better results than that of male speech. When considering the types of noise, the air-conditioner noise gave the best speech quality, while the train noise gave the worst speech quality. Conclusion: From the study, it can be seen that coding methods, types of noise, levels of noise, speech gender influence on the coding speech quality.

    Full Text Available Current methods for nasal spray formulations have been elementary evaluating the dripping characteristics of a formulation and have not assessed the behavior of the nasal formulation in the presence of varying types of mucus depending on the indication or diseased state. This research investigated the effects of nasal mucus on the dripping behavior of nasal formulations and focused on developing an improved in vitro analytical test method that is more physiologically relevant in characterizing nasal formulation dripping behavior. Method development was performed using simulated nasal mucus preparations for both healthy and diseased states as coatings for the dripping experiment representing a wide range of viscosity. Factors evaluated during development of this in vitro test method included amount of mucus, application of mucus, drying times, and compatibility of the mucus on a C18 Thin Layer Chromatography (TLC substrate. The dripping behavior of nasal formulations containing a range of 1% Avicel to 3.5% Avicel was assessed by actuating the nasal spray on a perpendicular TLC plate coated with either healthy or diseased simulated nasal mucus. After actuation of the nasal spray, the dripping of the formulation on the coated TLC plate was measured after the plate was repositioned vertically. The method that was developed generated reproducible results on the dripping behavior of nasal formulations and provided critical information about the compatibility of the formulation with the nasal mucus for different diseased states, aiding in nasal spray formulation development and physical characterization of the nasal spray.

    Background The purpose of this work was to determine the effectiveness and possible complications encountered with bilateral fascia lata lid suspension used to correct blepharoptosis in patients with Kearns-Sayre syndrome. Methods This was a retrospective study of seven patients with Kearns-Sayre syndrome who had a minimum of 1 year of follow-up. A bilateral fascia lata sling was used to correct the ptosis. Preoperative and postoperative measurements of the vertical lid fissure width (VFW) and marginal reflex distance (MRD) were performed. The Student’s t-test was used to analyze the results. Results The mean preoperative VFW and MRD measurements were 4±2.45 mm and 0.14±0.92 mm, respectively. The mean postoperative VFW and MRD measurements were 7.71±1.85 mm, and 2.86±1.69 mm, respectively. All preoperative and postoperative values were considered to be statistically significant (Plagophthalmos, and one patient developed corneal ulceration and scarring due to corneal exposure and a weak Bell’s phenomenon. Conclusion The surgical technique described to correct the blepharoptosis found in patients with Kearns-Sayre syndrome was found to be efficient and relatively safe. The correction should be conservative to decrease the risk of postoperative corneal damage that occurred in one patient. PMID:25565765

    The aim of this study is to report on speech outcomes following surgery for velopharyngeal insufficiency (VPI) on a broad spectrum of patients without a cleft palate. Inclusion criteria included patients without a cleft palate operated on by a single surgeon (JKW) over a 10-year period and postoperative speech evaluation within 1 year. All patients underwent a sphincter pharyngoplasty. The main outcome measures were perceptual speech assessment using a 6-point scale (1 = none or normal, 6 = severe); velopharyngeal function (VPF) (1 = adequate, 2 = marginal, 3 =  dequate); and quantitative nasalance score. Forty children (mean age 7.5 y) were included. Eight unique conditions were identified; the most common was 22q deletion syndromes (27.5%). All patients had a deep nasopharynx, mean nasopharyngeal depth >0.67. Two novel cases are presented in each child with mosaic Trisomy 14 and ring chromosome 18 abnormality. Of all patients, 87.5% improved their postoperative hypernasality score. Preoperatively, all patients had either marginal or inadequate VPF (2 or 3). Postoperatively, 90% of patients (n = 36) achieved adequate velar function, the remainder did not improve at the first postoperative evaluation. Intelligibility and audible nasal emissions improved in between 57% and 65% of patients. Articulation proficiency was the only perceptual rating not to improve initially, but then did so on the most recent postoperative speech evaluation. This study demonstrates successful speech outcomes in a diverse group of patients. It also increases awareness of noncleft VPI amenable to surgical correction.

The sEPSM applies the signal-tonoise ratio in the envelope domain (SNRenv), which was demonstrated...... to successfully predict speech intelligibility in conditions with nonlinearly processed noisy speech, such as processing with spectral subtraction. Moreover, a multiresolution version (mr-sEPSM) was demonstrated to account for speech intelligibility in various conditions with stationary and fluctuating...... from computational auditory scene analysis and further support the hypothesis that the SNRenv is a powerful metric for speech intelligibility prediction....

  9. Silver nasal sprays: misleading Internet marketing.

    Gaslin, Michael T; Rubin, Cory; Pribitkin, Edmund A

    2008-04-01

    Long-term use of silver-containing products is associated with a permanent bluish-gray discoloration of the skin known as argyria, but they remain widely available despite several measures by the FDA to regulate them. Several recent case reports have described the occurrence of argyria as a result of using these "natural" products. We used the five most common Internet search engines to find Web sites providing information on silver-containing nasal sprays. Of 49 Web sites analyzed, only 2 (4%) mentioned argyria as a possible complication, although 30 (61%) did caution against long-term use. Eight sites (16%) made specific claims about the health benefits of the product. All 49 sites (100%) provided direct or indirect links to buy silver-containing nasal sprays. We conclude that information about silver-containing nasal sprays on the Internet is misleading and inaccurate. Therefore, otolaryngologists should be aware of the misinformation their patients may be receiving about these products.

    2010-01-01

    The recommendation to change breathing patterns from the mouth to the nose can have a significantly positive impact upon the general well being of the individual. We classify nasal and mouth breathing by using an acoustic sensor and intelligent signal processing techniques. The overall purpose is to investigate the possibility of identifying the differences in patterns between nasal and mouth breathing in order to integrate this information into a decision support system which will form the basis of a patient monitoring and motivational feedback system to recommend the change from mouth to nasal breathing. Our findings show that the breath pattern can be discriminated in certain places of the body both by visual spectrum analysis and with a Back Propagation neural network classifier. The sound file recoded from the sensor placed on the hollow in the neck shows the most promising accuracy which is as high as 90%.

  11. Nasal birth trauma: a review of appropriate treatment.

    Cashman, E C

    2012-02-01

    The aetiology of nasal deformity has frequently included birth trauma. There is no consensus in the literature as to whether nasal surgery, in the form of closed reduction, is indicated in neonates. The majority of studies in the literature that advocate intervention have inadequate followup periods and there is a paucity of evidence for the adverse effects of conservative management. This case highlights the therapeutic dilemma posed by such nasal injuries in the neonate and, to the best of the authors\\' knowledge, at the time of writing, represents the earliest reported case in the literature of nasal deformity in the neonate. The term nasal deformity is used to denote deformity of the nasal pyramid, soft tissue, and septum. Three main aspects of neonatal nasal deformity are addressed including, firstly, if nasal deformity at birth needs to be addressed, secondly, if left unaltered, what the long-term effects are and, finally, if intervention alters the normal course of midfacial development.

    2010-06-01

    Full Text Available This paper presented phonetic evidence to resolve the transcription disagreement concerning the syllable-final nasal shift in the variety of Mandarin spoken in Taiwan. Although three judges agreed that the rhyme /iŋ/ underwent a sound change, they perceived the nasal coda shift differently. Two of them transcribed it as a modification from /iŋ/ to /in/, whereas the other asserted that the velar nasal disappears with its preceding vowel nasalized. In order to resolve this transcription conflict, this study analyzed the acoustic attributes of the speculative sound alterations in question, including /in/, /iŋ/, /i/ and /ĩ/. The phonetic analysis indicated that the Taiwanese participants did not nasalize the preceding vowel deleting the nasal coda but tended to pronounce the post-vocalic velar nasal as its dental counterpart. This study concluded by discussing the implications of the synchronic variation for the theories of the nasal coda shift in Chinese dialects.

    Full Text Available O condrossarcoma é uma neoplasia maligna proveniente de tecido cartilaginoso, cuja incidência em região de cabeça e pescoço é rara. É mais freqüente em pacientes do sexo masculino, entre a terceira e quarta décadas, e na face localiza-se no seio e osso maxilar, sendo raro no septo nasal. Esse relato descreve o caso de uma paciente do sexo feminino, de 13 anos de idade, que apresentava queixa de deformidade facial em região malar direita acompanhada de dores esporádicas. Ao exame físico apresentava um abaulamento de aproximadamente 3 cm de diâmetro em região malar esquerda, não sendo notada nenhuma alteração à rinoscopia anterior. Foram realizadas tomografia computadorizada (TC de seios paranasais, ressonância magnética de face e biópsia da lesão para estudo anatomopatológico, que inicialmente sugeria o diagnóstico de condroma. Após a exérese da massa, a paciente evoluiu com recidiva da lesão em apenas 5 meses. Diante deste fato surpreendente, foi requisitada a revisão da lâmina que evidenciou Condrossarcoma tipo I. Nova cirurgia foi realizada, visando a remoção do tumor, com tratamento radioterápico complementar. Atualmente, a paciente se encontra em acompanhamento ambulatorial, sem queixas álgicas e sem sinas de recidiva. Os condrossarcomas são tumores malignos de crescimento lento, mas localmente agressivos, tendo grande propensão a recidivas. A conduta é preferencialmente cirúrgica, uma vez que são pouco radiossensíveis e a quimioterapia é meramente paliativa. O objetivo deste estudo é apresentar um caso de condrossarcoma em seio maxilar, etmóide, esfenóide e septo, discutindo o quadro clínico, diagnóstico, fatores prognósticos e conduta.

With better understanding of the anatomy of the unilateral cleft lip and nasal deformities, primary correction of the nasal deformity at the time of lip repair, critical evaluation of short and long-term results following various treatment protocols, and constant striving for perfection in both aesthetics and function, we have been able to design improved treatment strategies and more accurate surgical techniques so as to achieve overall superior and long-lasting results. In this review article, we present our protocols and experience for functional and aesthetic correction of secondary unilateral cleft lip nasal deformities and a retrospective review of 219 consecutive patients treated at our Craniofacial Centre for correction of secondary unilateral cleft lip nasal deformities. The protocols used in the treatment of 219 consecutive patients at our Craniofacial Centre for correction of secondary unilateral cleft lip nasal deformities were reviewed. In addition, analysis of the most recent 51 consecutive patients who underwent complete clinical and functional evaluation with rhinomanometry followed by correction of the cleft lip nasal deformity was performed. A variety of time-honoured techniques of rhinoplasty were applied in the correction of the residual deformities to achieve symmetry, aesthetic balance, and functional correction of the nose. Follow-up ranged from 5-11 years. Analysis of the data revealed that 39 patients (76.47% had significant functional and aesthetic improvement; seven patients (13.07% had significant aesthetic improvement but a modest functional improvement; and five patients (9.8% required additional surgery to improve their appearance and had no functional improvement. Further analysis demonstrated that five out of seven patients in the second group had pharyngeal flaps in place that were primarily

    Larvae causing obligatory myiasis are numerous and they may affect cutaneous and subcutaneous tissues, wounds, nasopharyngeal cavities (nasal bots), internal organs and the digestive tract (bots) of domestic and wild animals and humans as well. Nasal bots belong to the Family Oestridae, Subfamily Oestrinae, which includes several important genera: Oestrus, Kirkioestrus, and Gedoelstia infecting Artiodactyla (except Cervidae) in Africa and Eurasia, Cephenemyia and Pharyngomyia infecting Cervidae, Rhinoestrus infecting horses, Cephalopina infecting camels, Pharyngobolus infecting African elephants, and Tracheomyia infecting Australian kangaroos. Nasal bots are widespread in Mediterranean and tropical areas and in affected animals they induce sneezing and nasal discharge which may become caked with dust making breathing very difficult. The aforementioned species of larvae are host-specific but sometimes the may be deposited in human eyes inducing a painful opthalmomyiasis of short duration. The first fascinating trait of these parasites is the very efficient morphological and biological adaptations to parasitism they show either as larvae or as adults, in order to facilitate their survival and search for a suitable host. Nasal bots have reached different degrees of complexity in their life cycles. Indeed, while for some species (e.g., Oestrus ovis, Rhinoestrus usbekistanicus) larvae are injected by flies directly into nostrils and develop in the sinuses before being ejected for external pupation, some other species migrate from eyes to blood before returning to nasal cavities either through the ethmoid bone (Gedoelstia hässleri) or via lungs and bronchi (Gedoelstia cristata). Moreover, larvae are very well-adapted to their environment being able to undergo through hypobiosis either inside or outside the host, according to the climatic environmental conditions and seasonality. The second fascinating trait of nasal bots is related to host behavioural and immune

    English speech has a very long history and always attached importance of people highly. People usually give a speech in economic activities, political forums and academic reports to express their opinions to investigate or persuade others. English speech plays a rather important role in English literature. The distinct theme of speech should attribute to the rhetoric. It discusses parallelism, repetition and rhetorical question in English speech, aiming to help people appreciate better the charm of them.

    Background: As a non-injection route for immunotherapy, local nasal immunotherapy has been examined in allergic rhinitis patients. However, it is unclear how the immunotherapy affects sneezing, biphasic nasal blockage and nasal hyperresponsiveness. Thus, we evaluated the therapeutic effects of nasal immunotherapy on the symptoms of guinea pig allergic rhinitis. Additionally, we also evaluated whether the immunotherapy relieved pollen-induced allergic conjunctivitis. Methods: Sensitized ani...

    2015-04-01

    Full Text Available Congenital nasal pyriform aperture stenosis (CNPAS is a rare cause of nasal airway obstruction that clinically mimics choanal atresia in a neonate. The differentiation between the two is very important as the management of the two conditions is different. Timely recognition is important to prevent fatal outcome. CNPAS may present as an isolated condition or with associated craniofacial anomalies. Despite typical findings of CNPAS being present on cross-sectional imaging, this condition is commonly overlooked, probably because of a lack of familiarity with the normal morphological features of the nasal cavity in infants and also owing to a lack of awareness of this rare entity. Here we report a case of CNPAS with pre- and post-surgical CT images and the complication that occurred owing to nasal stenting.

  19. Visual speech form influences the speed of auditory speech processing.

    Paris, Tim; Kim, Jeesun; Davis, Chris

    2013-09-01

    An important property of visual speech (movements of the lips and mouth) is that it generally begins before auditory speech. Research using brain-based paradigms has demonstrated that seeing visual speech speeds up the activation of the listener's auditory cortex but it is not clear whether these observed neural processes link to behaviour. It was hypothesized that the very early portion of visual speech (occurring before auditory speech) will allow listeners to predict the following auditory event and so facilitate the speed of speech perception. This was tested in the current behavioural experiments. Further, we tested whether the salience of the visual speech played a role in this speech facilitation effect (Experiment 1). We also determined the relative contributions that visual form (what) and temporal (when) cues made (Experiment 2). The results showed that visual speech cues facilitated response times and that this was based on form rather than temporal cues. Copyright © 2013 Elsevier Inc. All rights reserved.

    Effective communication between staff members is key to patient safety in hospitals. A variety of patient care activities including admittance, evaluation, and treatment rely on oral communication. Surprisingly, published information on speech intelligibility in hospitals is extremely limited. In this study, speech intelligibility measurements and occupant evaluations were conducted in 20 units of five different U.S. hospitals. A variety of unit types and locations were studied. Results show that overall, no unit had "good" intelligibility based on the speech intelligibility index (SII > 0.75) and several locations found to have "poor" intelligibility (SII speech intelligibility across a variety of hospitals and unit types, offers some evidence of the positive impact of absorption on intelligibility, and identifies areas for future research.

    Full Text Available Abstract Background There are few studies of the effects of nasal snuff and environmental factors on the risk of nasal cancer. This study aimed to investigate the impact of using nasal snuff and of other risk factors on the risk of nasal cancer in German men. Methods A population-based case–control study was conducted in the German Federal States of Bavaria and Baden-Württemberg. Tumor registries and ear, nose and throat departments provided access to patients born in 1926 or later. Results Telephone interviews were conducted with 427 cases (mean age 62.1 years and 2.401 population-based controls (mean age 60.8 years. Ever-use of nasal snuff was associated with an odds ratio (OR for nasal cancer of 1.45 (95% confidence interval [CI] 0.88–2.38 in the total study population, whereas OR in smokers was 2.01 (95% CI 1.00-4.02 and in never smokers was 1.10 (95% CI 0.43–2.80. The OR in ever-smokers vs. never-smokers was 1.60 (95% CI 1.24–2.07, with an OR of 1.06 (95% CI 1.05–1.07 per pack-year smoked, and the risk was significantly decreased after quitting smoking. Exposure to hardwood dust for at least 1 year resulted in an OR of 2.33 (95% CI 1.40–3.91 in the total population, which was further increased in never-smokers (OR 4.89, 95% CI 1.92–12.49 in analyses stratified by smoking status. The OR for nasal cancer after exposure to organic solvents for at least 1 year was 1.53 (1.17–2.01. Ever-use of nasal sprays/nasal lavage for at least 1 month rendered an OR of 1.59 (1.04–2.44. The OR after use of insecticides in homes was 1.48 (95% CI 1.04–2.11. Conclusions Smoking and exposure to hardwood dust were confirmed as risk factors for nasal carcinoma. There is evidence that exposure to organic solvents, and in-house use of insecticides could represent novel risk factors. Exposure to asbestos and use of nasal snuff were risk factors in smokers only.

    1995-07-01

    The problems of automatic recognition of and synthesis of multistyle speech have become important topics of research in recent years. This paper reports an extensive investigation of the variations that occur in the glottal excitation of eleven commonly encountered speech styles. Glottal waveforms were extracted from utterances of non-nasalized vowels for two speakers for each of the eleven speaking styles. The extracted waveforms were parametrized into four duration-related and two slope-related values. Using these six parameters, the glottal waveforms from the eleven styles of speech were analyzed both qualitatively and quantitatively. The glottal waveforms from each style speech were analyzed both qualitatively and quantitatively. The glottal waveforms from each style of speech have been shown to be significantly and identifiably different from all other styles, thereby confirming the importance of the glottal waveform in conveying speech style information and in causing speech waveform variations. The degree of variation in styled glottal waveforms has been shown to be consistent when trained on one speaker and compared with another.

  8. Speech therapy for errors secondary to cleft palate and velopharyngeal dysfunction.

    Kummer, Ann W

    2011-05-01

    Individuals with a history of cleft lip/palate or velopharyngeal dysfunction may demonstrate any combination of speech sound errors, hypernasality, and nasal emission. Speech sound distortion can also occur due to other structural anomalies, including malocclusion. Whenever there are structural anomalies, speech can be affected by obligatory distortions or compensatory errors. Obligatory distortions (including hypernasality due to velopharyngeal insufficiency) are caused by abnormal structure and not by abnormal function. Therefore, surgery or other forms of physical management are needed for correction. In contrast, speech therapy is indicated for compensatory articulation productions where articulation placement is changed in response to the abnormal structure. Speech therapy is much more effective if it is done after normalization of the structure. When speech therapy is appropriate, the techniques involve methods to change articulation placement using standard articulation therapy principles. Oral-motor exercises, including the use of blowing and sucking, are never indicated to improve velopharyngeal function. The purpose of this article is to provide information regarding when speech therapy is appropriate for individuals with a history of cleft palate or other structural anomalies and when physical management is needed. In addition, some specific therapy techniques are offered for the elimination of common compensatory articulation productions.

  9. Nasal Functional Evaluation Using Nasal Endoscopy, Acoustic Rhinometry, and Rhinomanometry on Nasal Airway-Obstructed Patients after Endoscopic Septoplasty, Corrective Rhinoplasty, and Internal Nasal Valve Surgery

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Objective: Rhinoplasty is a very common surgical procedure that is performed throughout the world as well as in our country for aesthetic concerns, nasal obstruction, or both. However, functional results still remain subjective, and compared to the vast number of operations, studies about functional results in the literature are very limited. The aim of this study is to evaluate respiratory functions after corrective rhinoplasty and to find the benefits both numerically and statistically. Material and Methods: Thirty patients who were admitted to our department with nasal obstruction based on the statements of the patients were included in the study. Patients who were admitted only for aesthetic considerations were excluded from the study. These patients were preoperatively evaluated with radiographic and endoscopic imaging; preoperative nasal resistance and nasal airway cross-sectional area values were measured and recorded with acoustic rhinometry and rhinomanometry devices. Then, patients were operated by open rhinoplasty technique, and measurements were repeated at three months and one year postoperative follow-ups. Results: As a result of measurements made with rhinomanometry one year after the surgery, a decrease in resistance value was observed in 20 patients, and an increase in minimal cross-sectional area measured with acoustic rhinometry was observed in 24 patients. The values measured by both methods were found to be statistically significant. Conclusion: As a result of our study, we advocate performing both functional and aesthetic rhinoplasty operations instead of functional or aesthetic purposes alone.

    2013-06-01

    Full Text Available Despite of improved survival of premature infants, the incidence of long term pulmonary complications, mostly associated with ventilation-induced lung injury, remains high. Non invasive ventilation (NIV is able to reduce the adverse effects of mechanical ventilation. Although nasal continuous positive airway pressure (NCPAP is an effective mode of NIV, traumatic nasal complications and intolerance of the nasal interface are common. Recently high flow nasal cannula (HFNC is emerging as an efficient, better tolerated form of NIV, allowing better access to the baby’s face, which may improve nursing, feeding and bonding. The aim of this review is to discuss the available evidence of effectiveness and safety of HFNC in preterm newborns with respiratory distress syndrome (RDS. It is known that distending pressure generated by HFNC increases with increasing flow rate and decreasing infant size and varies according to the amount of leaks by nose and mouth. The effects of HFNC on lung mechanics, its clinical efficacy and safety are still insufficiently investigated. In conclusion, there is a growing evidence of the feasibility of HFNC as an alternative mode of NIV. However, further larger randomized trials are required, before being able to recommend HFNC in the treatment of moderate respiratory distress of preterm infants.

    To determine the frequency of staphylococcal nasal carriage of health care workers (HCWs) and antimicrobial susceptibility profile of the isolates for appropriate decolonization therapy. An observational study. The study was conducted at Holy Family Hospital, Rawalpindi, during the period from May 2007 to April 2008. Nasal swabs from anterior nares of HCWs were cultured and identified as Staphylococcus aureus, coagulasenegative staphylococci (CoNS), methicillin-resistant S. aureus (MRSA), methicillin-resistant CoNS (MRCoNS) by using standard methods. Antimicrobial susceptibility testing was performed on Muller Hinton Agar using disc diffusion method. Of the 468 HCWs, 213 (45.5%) participants were men and 255 (54.5%) were women. Eighty five (18.2%) were nasal carriers of S. aureus, 07 (1.5%) for MRSA, 343 (73.3%) for CoNS and 10 (2.1%) for MRCoNS. The highest carriage rate for S. aureus was in midwives (30%) followed by maintenance staff (28.6%), security guards (25%), technicians (23.5%), staff nurses (22.7%) and 90% of S. aureus and CoNS were susceptible to amikacin, gentamicin and fluoroquinolones tested. Fluoroquinolones, preferably oral levofloxacin in combination with topical gentamicin ointment, in places like Pakistan where mupirocin is not routinely available, can be used for decolonization of nasal staphylococcal carriage.

    1991-03-01

    Nasal structural reconstruction is a formidable task in cases where there is loss of support to both the nasal dorsum and tip. A multitude of surgical approaches and materials have been used for the correction of the saddle-nose deformity with varying degrees of success. Articulated irradiated rib cartilage inserted through an external rhinoplasty approach was used to reconstruct nasal deformities in 18 patients over a 6-year period. Simultaneous use of a midline forehead flap to reconstruct the overlying soft tissue was required in four cases. Follow-up ranged from 1 to 6 years (mean, 2.8 years). Results were rewarding in most cases with marked improvement in nasal support and airway. Revision and/or replacement secondary to trauma or warping of the graft was required in four cases. None of the patients exhibited infection, extrusion, or noticeable resorption. A description of the surgical technique, review of all the cases, and recommendation for continued use of this graft material are discussed.

    We tested four normosmics and four anosmics in detection thresholds for six terpenes commonly found indoors: cumene, p-cymene, delta-3-carene, linalool, 1,8-cineole and geraniol. Normosmics provided odor thresholds and anosmics provided nasal pungency thresholds. All subjects provided nasal localization (i.e., right/left nostril) and eye irritation thresholds. Each type of threshold was measured eight times per subject-stimulus combination. Stimuli were presented from squeeze bottles in a two-alternative forced-choice procedure via an ascending method of limits. Odor thresholds ranged between 0.1 and 1.0 parts per million (ppm, by volume). Nasal pungency thresholds lay about three orders of magnitude above odor thresholds. Nasal localization and eye irritation thresholds did not differ between normosmics and anosmics, and fell close to nasal pungency thresholds. Olfactory thresholds could be obtained for all stimuli in all repetitions using the criterion of five correct choices in a row. Trigeminal thresholds (i.e., pungency, localization and eye irritation) could be obtained on all repetitions only for some terpenes using that same criterion. Carene and cineol produced nasal pungency and eye irritation on all repetitions. None of the terpenes could be localized on all repetitions, but cineol was localized a higher percentage of instances than were the other stimuli. At the other extreme, geraniol failed to evoke any of the three trigeminal responses in most instances. Overall, the results indicate that the three trigeminal thresholds produce a uniform view of the potency of these terpenes, with nasal pungency and eye irritation being slightly more sensitive than nasal localization. Furthermore, application of a previously derived linear solvation energy relationship to the results reinforced the view that physicochemical properties can predict the chemesthetic impact of volatile organic compounds.

    2016-09-01

    In this paper, we present the results of coblation nasal septal swell body (NSB) reduction for the treatment of nasal obstruction in patients with abnormally thickened NSB. The study design was a retrospective clinical series conducted at a single tertiary medical center. Eight patients underwent coblation NSB reduction. Pre-operative and post-operative nasal functions were evaluated by acoustic rhinometry and subjective symptom scales. We also analyzed pre-operative CT scan images and nasal endoscopic findings. The mean maximal NSB width was 16.4 ± 2.2 mm on pre-operative coronal CT scan images. The mean visual analog scale score for nasal obstruction was decreased from preoperative 7.63 ± 0.99 points to 3.88 ± 0.92 points (postoperative 3 months), 4.16 ± 0.78 points (postoperative 6 months), and 4.63 ± 0.69 points (postoperative 1 year). Six out of the eight patients were satisfied with the clinical outcome at 1 year after the procedure. To the best of our knowledge, coblation NSB reduction has not yet been reported in the medical literature. Our results show that it can be an effective treatment modality for nasal valve narrowing in patients with abnormally thickened NSB.

    Skeletal anterior open bite (AOB) or apertognathism is characterized by the absence of contact of the anterior teeth and affects articulation parameters, chewing, biting and voice quality. The treatment of AOB consists of orthognatic surgical procedures. The aim of this study was to evaluate the effects of treatment on voice quality, articulation and nasality in speech with respect to skeletal changes. The study was prospective; 15 patients with AOB were evaluated before and after surgery. Lateral cephalometric x-ray parameters (facial angle, interincisal distance, Wits appraisal) were measured to determine skeletal changes. Before surgery, nine patients still had articulation disorders despite speech therapy during childhood. The voice quality parameters were determined by acoustic analysis of the vowel sound /a/ (fundamental frequency-F0, jitter, shimmer). Spectral analysis of vowels /a/, /e/, /i/, /o/, /u/ was carried out by determining the mean frequency of the first (F1) and second (F2) formants. Nasality in speech was expressed as the ratio between the nasal and the oral sound energies during speech samples. After surgery, normalizations of facial skeletal parameters were observed in all patients, but no statistically significant changes in articulation and voice quality parameters occurred despite subjective observations of easier articulation. Any deterioration in velopharyngeal insufficiency was absent in all of the patients. In conclusion, the surgical treatment of skeletal AOB does not lead to deterioration in voice, resonance and articulation qualities. Despite surgical correction of the unfavourable skeletal situation of the speech apparatus, the pre-existing articulation disorder cannot improve without professional intervention.

  2. Nasal surgery in patients with systemic disorders

    Directory of Open Access Journals (Sweden)

    Sachse, Florian

    2010-01-01

    Full Text Available Multisystemic disorders represent a heterogenous group of diseases which can primarily manifest at the nose and paranasal sinuses as limited disease or secondarily as part of systemic involvement. Rhinologists therefore play an important role in the diagnostic but also therapeutic process. Although therapy of multisystemic disorders is primary systemic, additional rhinosurgery may become necessary. The spectrum of procedures consists of sinus surgery, surgery of the orbit and lacrimal duct, septorhinoplasty and closure of nasal septal perforation. Since the prevalence of most systemic diseases is very rare, recommendations are based on the analysis of single case reports and case series with a limited number of patients only. Although data is still limited, experiences published so far have shown that autologous cartilage or bone grafts can be used in nasal reconstruction of deformities caused by tuberculosis, leprosy, Wegener’s granulomatosis, sarcoidosis and relapsing polychondritis. Experiences gained from these diseases support the concept that well-established techniques of septorhinoplasty can be used in systemic diseases as well. However, a state of remission is an essential condition before considering any rhinosurgery in these patients. Even under these circumstances revision surgery has to be expected more frequently compared to the typical collective of patients undergoing septorhinoplasty. In addition, experiences gained from saddle nose reconstruction may in part be of value for the treatment of nasal septal perforations since implantation of cartilage grafts often represents an essential step in multilayer techniques of closure of nasal septal perforations. Aside from the treatment of orbital complications sinus surgery has been proven beneficial in reducing nasal symptoms and increasing quality of life in patients refractory to systemic treatment.

    Submicroscopic duplications along the long arm of the X-chromosome with known phenotypic consequences are relatively rare events. The clinical features resulting from such duplications are various, though they often include intellectual disability, microcephaly, short stature, hypotonia, hypogonadism and feeding difficulties. Female carriers are often phenotypically normal or show a similar but milder phenotype, as in most cases the X-chromosome harbouring the duplication is subject to inactivation. Xq28, which includes MECP2 is the major locus for submicroscopic X-chromosome duplications, whereas duplications in Xq25 and Xq26 have been reported in only a few cases. Using genome-wide array platforms we identified overlapping interstitial Xq25q26 duplications ranging from 0.2 to 4.76 Mb in eight unrelated families with in total five affected males and seven affected females. All affected males shared a common phenotype with intrauterine- and postnatal growth retardation and feeding difficulties in childhood. Three had microcephaly and two out of five suffered from epilepsy. In addition, three males had a distinct facial appearance with congenital bilateral ptosis and large protruding ears and two of them showed a cleft palate. The affected females had various clinical symptoms similar to that of the males with congenital bilateral ptosis in three families as most remarkable feature. Comparison of the gene content of the individual duplications with the respective phenotypes suggested three critical regions with candidate genes (AIFM1, RAB33A, GPC3 and IGSF1) for the common phenotypes, including candidate loci for congenital bilateral ptosis, small head circumference, short stature, genital and digital defects.

    Neurinoma grows in the modulated nerve with Schwann cells, and is observed for all positions of the body. It is comparatively rare for neurinoma to grow in the nasal cavity and paranasal sinuses, however. We report a case of neurinoma of the nasal septum. A 24-year-old man seen for nasal obstruction was found in anterior rhinoscopy to have a tumor of the bilateral nasal cavity. Computed tomography (CT) showed a soft tissue density mass in the anterior part of the nasal cavity. Because we suspected neurinoma from biopsy, we resected the tumor by Denker's operation under general anesthesia. We found that it originated from the nasal septum. Histopathological findings of the tumor indicated an Antoni A type neurinoma. After surgery, cartilago costalis was transplanted the plastic surgery to correct the defect in the nasal septum. The post operative course was good and no signs of recurrence were seen. This is the 19th case found in the literature.

    Full Text Available Introduction: Patients with dentofacial deformities may benefit from orthognathic surgery in the maxilla. Maxillary osteotomy may include procedures in the bone, cartilaginous, and soft tissues of the nose, leading to shape alterations. Objective: To evaluate the anatomic alterations of the nasal region in patients undergoing a Le Fort I osteotomy for advancement or superior impaction. Methods: This is a clinical prospective study. Twenty-one patients were evaluated during the preand postoperative periods. The positioning of the nasal tip and the modification of the nasal base were evaluated. Results: The results showed that the nasal tip was superiorly positioned in 85% of the cases, advanced in 80%, rotated in 80%, and there was a wide nasal base in 95%, resulting in esthetic improvement. Conclusions: Surgeries of maxillary advancement and superior reposition tend to cause elevation and advancement of the nasal tip, as well as enlargement of the nasal base.

    With the current worldwide workforce shortage of Speech-Language Pathologists, new and innovative ways of delivering therapy to children with speech sound disorders are needed. Computer-based speech therapy may be an effective and viable means of addressing service access issues for children with speech sound disorders. To evaluate the efficacy of computer-based speech therapy programs for children with speech sound disorders. Studies reporting the efficacy of computer-based speech therapy programs were identified via a systematic, computerised database search. Key study characteristics, results, main findings and details of computer-based speech therapy programs were extracted. The methodological quality was evaluated using a structured critical appraisal tool. 14 studies were identified and a total of 11 computer-based speech therapy programs were evaluated. The results showed that computer-based speech therapy is associated with positive clinical changes for some children with speech sound disorders. There is a need for collaborative research between computer engineers and clinicians, particularly during the design and development of computer-based speech therapy programs. Evaluation using rigorous experimental designs is required to understand the benefits of computer-based speech therapy. The reader will be able to 1) discuss how computerbased speech therapy has the potential to improve service access for children with speech sound disorders, 2) explain the ways in which computer-based speech therapy programs may enhance traditional tabletop therapy and 3) compare the features of computer-based speech therapy programs designed for different client populations.

    Full Text Available Background Pathogens in the nasal cavity during nasal surgery could lead to a systemicinfectious condition, such as bacteremia, nosocomial infection, or toxic shock syndrome.However, there is no research about the prevalence of nasal carriage in patients with nasalbone fracture.Methods This was a prospective, double-blind, randomized study about the rate of nasalcarriage in 200 patients with nasal bone fracture in Korea. Nasal secretions were taken fromboth the middle nasal meatus and colonized. All analyses were carried out using SPSS software.Results Pathogens were identified in 178 of the 200 cases. Coagulase-negative staphylococci(CNS were the most cultured bacteria in 127 (66.84% of the 190 total patients after excluding10 cases of contaminated samples, and methicillin-resistant coagulase-negative staphylococci(MRCNS were found in 48 (25.26%. Staphylococcus aureus was the second mostidentified pathogen, found in 36 (18.95%, followed by 7 cases (3.68% of methicillin-resistantStaphylococcus aureus (MRSA. The prevalence rate of MRSA in the females was higher thanthat in the males (RR=4.70; 95% CI, 1.09-20.18, but other demographic factors had no effecton the prevalence rate of MRSA and MRCNS.Conclusions The prevalence rate of these pathogens in patients with nasal bone fracture inKorea was similar to other reports. However, few studies have addressed the prevalence rateof CNS and MRCNS in accordance with risk factors or the change in prevalence according tospecific prophylaxis against infectious complications.

    There is no doubt that perceptual speech assessment and instrumental examination could provide different diagnostic information on patients with cleft palate (CP), but not all patients simultaneously need the 2 examinations. So the purposes of this study were to explore a simple and effective evaluation method to assess velopharyngeal function and to investigate speech traits that affect the diagnosis of velopharyngeal function in patients with CP. The investigators implemented a retrospective study, and 247 postoperative patients with CP were selected, including 155 boys and 92 girls, with a mean (SD) age of 13 years and 2 months (7 years and 7 months). All of these patients were assessed by perceptual speech evaluation and nasopharyngoscopy after surgery, and the result was divided into velopharyngeal closure (VPC), velopharyngeal insufficiency, and marginal VPC. The number of diagnostic consistency patients was 170 (VPC, 51 patients; velopharyngeal insufficiency, 115 patients; marginal VPC, 4 patients), and the consistent ratio was 68.83%. There was no significant difference between perceptual speech assessment and nasopharyngoscopy. Furthermore, the difference in distribution of hypernasality between the consistent group and the inconsistent group was significant. In addition, the correlation analysis indicated that surgical age, hypernasality, nasal emission, and compensatory articulation were correlated with the velopharyngeal function (P velopharyngeal function. Much more attention should be paid to the surgical age, the alteration of hypernasality, nasal emission, and compensatory articulation during CP therapy.

    Palatal integrity is essential for useful speech, deglutition, good oral hygiene, and prevention of nasal regurgitation. Maxillary defects after tumor extirpation, therefore, can have serious functional and cosmetic implications. Given the often disappointing results obtained with local and regional pedicled flaps for maxillary reconstruction, a variety of microvascular free flaps have been utilized in recent years, including the rectus abdominis, fibular, radial forearm, and latissimus dorsi flaps. Experience with these techniques has been documented in a limited number of case reports. We describe our single-stage approach to maxillary and nasal floor reconstruction with the double skin-paddle rectus abdominis musculocutaneous free flap. A series of five patients is presented; six of these immediate free flap reconstructions were performed for defects resulting from tumor resection. A vertical rectus abdominis musculocutaneous free flap was used in all cases, designing two separate skin paddles to accommodate the measured maxillary and nasal floor deficiencies. Anastomoses of the deep inferior epigastric artery and vena comitans were performed end-to-end to the facial artery and vein, respectively. In addition, orbital floor reconstruction with calvarial bone grafts or titanium mesh was performed in all five patients. Separation of the oral and nasal cavities was maintained postoperatively. No intraoperative complications, perioperative mortalities, flap losses, instances of skin paddle necrosis, hematomas, or oronasal fistulae were observed. One patient required bedside drainage of a surgical site abscess that resolved without adverse sequelae. Over the past 4 years, the double skin-paddle rectus abdominis musculocutaneous free flap has provided reliable results at our institution for single-stage reconstruction of maxillary and nasal floor defects. This reconstructive technique should be considered a viable method that can alleviate the functional and cosmetic

  5. Denial Denied: Freedom of Speech

    Full Text Available Free speech is a widely held principle. This is in some ways surprising, since formal and informal censorship of speech is widespread, and rather different issues seem to arise depending on whether the censorship concerns who speaks, what content is spoken or how it is spoken. I argue that despite these facts, free speech can indeed be seen as a unitary principle. On my analysis, the core of the free speech principle is the denial of the denial of speech, whether to a speaker, to a proposition, or to a mode of expression. Underlying free speech is the principle of freedom of association, according to which speech is both a precondition of future association (e.g. as a medium for negotiation and a mode of association in its own right. I conclude by applying this account briefly to two contentious issues: hate speech and pornography.

    2014-01-01

    Full Text Available The correction of cleft lip nasal deformity is challenging and there have been numerous methods described in the literature with little demonstrated technical superiority of one over another. The common clinical issues associated with cleft lip nasal deformity are its lack of symmetry, alar collapse on the affected side, obtuse nasal labial angle, short nasal length, loss of tip definition, and altered columella show among others. We carried out augmentation of cleft lip rhinoplasties with rib graft in 16 patients over the one-year study period. Each of these patients was reviewed and given questionnaire before and after surgery to evaluate their response on the outcome to the approach. Preoperatively, nasal asymmetry is the main complaint (14/16, 87.5% among our series of patients. Postoperatively, 12 (75% patients out of the 16 reported significant improvement in their nasal symmetry with the other four marginal. All patients reported excellent nasal projection postoperatively with good nasal tip definition. Our series of patients reported overall good satisfaction outcome and will recommend this procedure to other patients with cleft lip nasal deformity. In conclusion, augmentation of cleft lip rhinoplasty can be employed to achieve perceivable and satisfactory outcome in patients with cleft lip nasal deformity.

    Full Text Available Wide field fundus imaging is needed to diagnose, treat, and follow-up patients with retinal pathology. This is more applicable for pediatric patients as repeated evaluation is a challenge. The presently available imaging machines though provide high definition images, but carry the obvious disadvantages of either being costly or bulky or sometimes both, which limits its usage only to large centers. We hereby report a technique of fundus imaging using a nasal endoscope coupled with viscoelastic. A regular nasal endoscope with viscoelastic coupling was placed on the cornea to image the fundus of infants under general anesthesia. Wide angle fundus images of various fundus pathologies in infants could be obtained easily with readily available instruments and without the much financial investment for the institutes.

  9. Saline Nasal Irrigation for Upper Respiratory Conditions

    Science.gov (United States)

    2009-01-01

    Acute and chronic upper respiratory conditions are common and expensive disorders with enormous impact on patient quality of life and society at large. Saline nasal irrigation (SNI), a therapy with roots in Ayurvedic medicine that bathes the nasal mucosa with in spray or liquid saline, has been used as adjunctive care for upper respiratory conditions. In liquid form, SNI has been found to be effective adjunctive care by the Cochrane Collaboration for symptoms associated with chronic rhinosinusitis. Less conclusive clinical trial evidence supports its use in spray and liquid forms as adjunctive treatment for mild-to-moderate allergic rhinitis and acute upper respiratory infections. Consensus or expert opinion recommendations exist for SNI as a treatment for a variety of other conditions including rhinitis of pregnancy. SNI appears safe; side effects are minimal and transient. It can be recommended by clinicians to interested patients with a range of upper respiratory conditions in the context of patient education and printed instructional handouts. PMID:19904896

    2016-05-01

    Full Text Available Septoplasty is one of the most commonly performed surgeries in rhinology to relieve nasal obstruction of patients with distortion in the midline cartilage or septum of the nose to relieve nasal obstruction of patient and findings consistent with nasal endoscopy. The anterior nasal packing routinely done following septoplasty is usually conventional and not evidence based. The purpose of nasal packing is to obtain haemostasis, enhance opposition of septal flaps, avoid septal haematoma formation, close the dead space, avoid synechiae formation, provide support to septal cartilage and prevent its displacement. OBJECTIVE This study intends to evaluate the effects of nasal packing on surgical success and related complications in septoplasty. MATERIALS AND METHODS The present clinical prospective and randomised study was carried out on patients attending Otorhinolaryngology Department of Santhiram Medical College & General Hospital between March 2012 and March 2015. Patients undergoing septoplasty were randomised either to receive anterior nasal packing or to not receive nasal packing postoperatively. RESULTS Levels of pain experienced by patients with nasal packing postoperatively during the initial 24 hours postoperatively and during the removal of the pack were significantly more. Post-operative headache, epiphora, swallowing discomfort and sleep disturbance were more in patients with nasal packing and statistically (p.05. Septal haematoma, adhesions and local infections in both groups were statistically insignificant (p>.05. CONCLUSION Septoplasty enhances the standard of living of patients with septal deviation and nasal obstruction. Our study results suggest that nasal packing after septoplasty is not obligatory. Nasal packing causes considerably more pain and complications, and it should be reserved only for those who have bleeding predisposition.

    A syndrome encompassing postnatal onset of short stature, widow's peak, ptosis, posteriorly angulated ears, and limitation of forearm supination is reported in a boy and his mother. The boy has not yet experienced dislocation of patella or other joint anomaly except for limitation of supination of the forearms. On the other hand, the mother has a milder limitation of supination only on the left arm and is devoid of ptosis. Their condition is reminiscent of that described in the family reported by Kapur et al. [1989: Am. J. Med. Genet. 33: 357-363.], which showed an X-linked dominant mode of inheritance. DNA study on our family using an intragenic polymorphism of the Aarskog syndrome (FGD1) gene and four other adjacent markers convincingly excludes the possibility that their condition could be caused by a mutation of the FGD1 gene. Our family and the family reported by Kapur et al. may suggest segregation of a novel X-linked dominant condition.

    The present study was aimed to investigate the effects of DNS on the structure of nasal cavity. The paranasal sinus coronal view CT of 108 patients with DNS and 129 hospitalized patients without DNS was retrospectively analyzed. The transverse diameter of nasal cavity (a), transverse diameter of nasal cavity and paranasal sinus (b), angle between maxillary and palatal bone, interalveolar distance, and maxillary rotation distance were measured. The ratio of a/b in experimental group was 0.367 ± 0.006 which was significantly (P = 0.0023) less than that in control group (0.391 ± 0.005). For the angle between maxillary and palatal bone, there was no significant difference found between DNS and control group for both right and left sides. The interalveolar distance was 40.75 mm in experimental group, and 38.8 mm in control (P = 0.0002). For the maxillary rotation distance, findings were considered as significant (P DNS affects the development of nasal cavity and paranasal sinus, as well as increases the interalveolar distance and maxillary rotation distance. These influences may be caused by the alteration of airflow inside the nasal cavities.

Se practicó examen clínico y biopsia de la neoplasia visible en la cavidad nasal izquierda. La ubicación y extensión del tumor fue determinada mediante tomografía computarizada de cabeza y cuello. Se realizaron análisis histopatológico e inmunohistoquímico (IHQ del tejido tumoral. La tomografía computarizada evidenció una masa con densidad de tejido blando de 10 cm de longitud x 3.5 cm de diámetro y escasa captación de medio de contraste, que comprometía en su totalidad la cavidad nasal derecha y parte de la porción posterior de la coana izquierda. El análisis histopatológico reveló numerosas células redondas pleomórficas con poco citoplasma, rodeadas por trama escasa de tejido conectivo y bajo índice mitótico. En el examen IHQ la muestra fue negativa a los antígenos CD3 y CD20 para linfocitos T y B, respectivamente. Los hallazgos clínicos y de la tomografía computarizada, así como los resultados del análisis histopatológico del tejido tumoral, fueron compatibles con un plasmocitoma extramedular nasal de bajo grado de malignidad.

    Various authors have pointed out that humans can become quite adept at deriving phonetic transcriptions from speech spectrograms (as good as 90percent accuracy at the phoneme level). The authors describe an expert system which attempts to simulate this performance. The speech spectrogram expert (spex) is actually a society made up of three experts: a 2-dimensional vision expert, an acoustic-phonetic expert, and a phonetics expert. The visual reasoning expert finds important visual features of the spectrogram. The acoustic-phonetic expert reasons about how visual features relates to phonemes, and about how phonemes change visually in different contexts. The phonetics expert reasons about allowable phoneme sequences and transformations, and deduces an english spelling for phoneme strings. The speech spectrogram expert is highly interactive, allowing users to investigate hypotheses and edit rules. 10 references.

  18. RECOGNISING SPEECH ACTS

    Directory of Open Access Journals (Sweden)

    Phyllis Kaburise

    2012-09-01

    Full Text Available Speech Act Theory (SAT, a theory in pragmatics, is an attempt to describe what happens during linguistic interactions. Inherent within SAT is the idea that language forms and intentions are relatively formulaic and that there is a direct correspondence between sentence forms (for example, in terms of structure and lexicon and the function or meaning of an utterance. The contention offered in this paper is that when such a correspondence does not exist, as in indirect speech utterances, this creates challenges for English second language speakers and may result in miscommunication. This arises because indirect speech acts allow speakers to employ various pragmatic devices such as inference, implicature, presuppositions and context clues to transmit their messages. Such devices, operating within the non-literal level of language competence, may pose challenges for ESL learners.

    2015-01-01

    Surgical resection of soft palate due to cancer affects the effective functioning of the velopharyngeal mechanism (speech and deglutition). With the loss of speech intelligibility, hyper resonance in voice and impaired function of swallowing (due to nasal regurgitation), there is a depreciation in the quality of life of such an individual. In a multidisciplinary setup, the role of a prosthodontist has been described to rehabilitate such patients by fabrication of speech aid prosthesis. The design and method of fabrication of the prosthesis are simple and easy to perform. The use of prosthesis, together with training (of speech) by a speech pathologist resulted in improvement in speech. Furthermore, an improvement in swallowing had been noted, resulting in an improved nutritional intake and general well-being of an individual. The take-home message is that in the treatment of oral cancer, feasible, and rapid rehabilitation should be endeavored in order to make the patient socially more acceptable. The onus lies on the prosthodontist to practise the same in a rapid manner before the moral of the patient becomes low due to the associated stigma of cancer.

  8. The Usefulness of Nasal Packing with Vaseline Gauze and Airway Silicone Splint after Closed Reduction of Nasal Bone Fracture

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available BackgroundPacking after closed reduction of a nasal bone fracture causes inconvenient nasal obstruction in patients. We packed the superior meatus with Vaseline gauze to support the nasal bone, and packed the middle nasal meatus with a Doyle Combo Splint consisting of an airway tube, a silastic sheet, and an expandable sponge to reduce the inconvenience. In addition, we aimed to objectively identify whether this method not only enables nasal respiration but also sufficiently supports the reduced nasal bone.MethodsNasal ventilation was measured via spirometry 1 day before surgery and compared to 1 day after surgery. To compare support of the reduced nasal bone by the 2 methods, 2 plastic surgeons assessed the displacementon X-rays taken after the surgery and after removing the packing. The extent of nasal obstruction, dry mouth, sleep disturbance, headache, and swallowing difficulty were compared with visual analog scales (VAS on a pre-discharge survey.ResultsIn the experimental group, the nasal respiration volume 1 day after surgery remained at 71.3%±6.84% on average compared to 1 day prior to surgery. Support of the reduced bone in the experimental group (2.80±0.4 was not significantly different from the control group (2.88±0.33. The VAS scores for all survey items were lower in the experimental group than in the control group, where a lower score indicated a lower level of inconvenience.ConclusionsThe nasal cavity packing described here maintained objective measures of nasal respiration and supported the reduced bone similar to conventional methods. Maintaining nasal respiration reduced the inconvenience to patients, which demonstrates that this packing method is useful.

    Full Text Available The nasal polyposis is a chronic inflammatory process of the nasal mucosa. Although it is rare in children, there may be also association with cystic fibrosis and primary ciliary dyskinesia. About 50% of primary ciliary dyskinesia patients develop situs inversus and it is known as Kartagener's syndrome. The Kartagener's sydrome is a rare autosomal recessive disorder characterized by sinusitis, bronchiectasis, situs inversus. Clinically, patients present to the otolaryngologist with nasal obstruction. We as pediatricians, should consider nasal polyposis as a rare cause of nasal obstruction in children. In the presence of recurrent upper and lower respiratory tract infections accompanying nasal polyposis, Kartagener's syndrome must be kept in mind as a rare reason.

  14. Speech transmission index from running speech: A neural network approach

    Science.gov (United States)

    Li, F. F.; Cox, T. J.

    2003-04-01

    Speech transmission index (STI) is an important objective parameter concerning speech intelligibility for sound transmission channels. It is normally measured with specific test signals to ensure high accuracy and good repeatability. Measurement with running speech was previously proposed, but accuracy is compromised and hence applications limited. A new approach that uses artificial neural networks to accurately extract the STI from received running speech is developed in this paper. Neural networks are trained on a large set of transmitted speech examples with prior knowledge of the transmission channels' STIs. The networks perform complicated nonlinear function mappings and spectral feature memorization to enable accurate objective parameter extraction from transmitted speech. Validations via simulations demonstrate the feasibility of this new method on a one-net-one-speech extract basis. In this case, accuracy is comparable with normal measurement methods. This provides an alternative to standard measurement techniques, and it is intended that the neural network method can facilitate occupied room acoustic measurements.

    Background: The management of chronic rhinosinusitis with nasal polyposis (CRSwNP) involves both surgical and medical approaches, and remains a controversial subject. Objective: The objective of this prospective, randomized, controlled trial was to compare the medical and surgical treatments of CRSwNP in terms of their effect on the nasal congestion index (NCI). Methods: Forty-eight patients with CRSwNP were randomized either to medical or surgical therapy. Pretreatment and 3- and 6-month posttreatment assessments of the visual analog scale score, the 20-Item Sino-Nasal Outcome Test, saccharine clearance time, nasal endoscopy, and NCI measurement with acoustic rhinometry were performed. Forty-one subjects were included in the analysis. Results: Both the medical and surgical interventions for CRSwNP resulted in significant improvement in the visual analog scale score, 20-Item Sino-Nasal Outcome Test, saccharine clearance time, and nasal endoscopic examination scores. There was no difference between the two groups in terms of the percentage change from baseline for any of the parameters at the 6-month posttreatment assessment. NCI showed no significant difference from baseline. Similarly, no significant difference was found between the medical and surgical groups in terms of their effect on the NCI (p > 0.05). Conclusion: Because NCI does not correlate with standard subjective measures in outcomes for this group of patients, it cannot be used as an outcome measurement of treatment of subjects with CRSwNP. Results of this prospective randomized study did not find any additional benefit of surgical therapy over medical therapy in subjects with CRSwNP.

    Continuous positive airway pressure (CPAP) with nasal devices (nCPAP) is widely used in the respiratory management of newborns. The present study aimed to compare the incidence of nasal trauma secondary to nasal continuous positive airway pressure (nCPAP) protected with or without hydrocolloid dressing in preterm infants. This prospective controlled study was performed in the neonatal intensive care unit (NICU) of the Children's Hospital of Hunan Province from March 1, 2010 to June 31, 2010. A total of 65 infants, 46 males and 19 females, were recruited in this study. Their average gestational age was 32.6 weeks (range 28-37 weeks). The infants were randomly divided into clinical trial group (group A, n=33) and control group (group B, n=32). Paraffin oil was smeared around the nostrils before inserting prongs in group B; the infants in group A were covered on the infant's nostrils surface with hydrocolloid dressing (hydrocolloid dressing, 1.8 mm thick, 90029T, 3M Company, Minnesota, USA) with a size of 2-3 cm cutting two holes adapted to the nose and nostrils. The nostrils of those infants were inspected daily during nCPAP support until they were weaned off nCPAP. Nine infants (2 in group A and 7 in group B) developed nasal injury during nCPAP support. The Chi-square test revealed that there was a statistically significant difference (P=0.01) in the incidence of nasal injury between groups A and B. The study demonstrated that hydrocolloid dressing significantly decreased the incidence and the severity of nasal injury.

    The purpose of this paper is to describe the outcome of muscle-building therapy for nasal muscles in cases of nasal valve stenosis or collapse. The present study was performed to investigate the best way to combine transcutaneous and intranasal surface electromyography (sEMG) biofeedback training of muscles involved in nasal valve function with a home exercise program and electric stimulation of nasal muscles. A randomized pilot study of 3 groups of patients (n1=12, n2=12, n3=10; total 34 patients) presenting with symptoms of obstructed nasal breathing was conducted. All selected patients demonstrated nasal valve stenosis with a positive Cottler maneuver and clinically evident nasal valve collapse. Follow-up ranged from 8 to 12 months. Treatment for Group 1 included transcutaneous and intranasal electric stimulation of nasal muscles only. Treatment for Group 2 included biofeedback training and home exercise program of specific nasal movements, and treatment for Group 3 included surface and intranasal EMG biofeedback assisted specific strategies for nasal muscle education, home exercises and electric stimulation. All patients in these groups exhibited subjective improvement. For Group 3, in 80% the improvement was proved objectively; for Group 2, in 75% the improvement was proved objectively; for Group 1, in 58,33% the improvement was proved objectively. We found no significant difference between the results in Groups 3 and 2 and poorer results in Group 1. Relieve of nasal valve stenosis and collapse can be achieved with a complex muscle-building therapy as described. It helps a significant cohort of patients with symptoms of obstructed nasal breathing to avoid surgical intervention. Electric stimulation of the muscles does not contribute significantly in achieving of good results.

Conversational speech samples from seven speakers were evaluated for the frequency and types of disfluencies and speech rate. The centenarian speakers had a disfluency rate similar to that reported for 70-, 80-, and early 90-year-olds. The types of disfluencies observed also were similar to those reported for younger elderly speakers (primarily whole word/phrase, or formulative fluency breaks). Finally, the speech rate data for the current group of speakers supports prior literature reports of a slower rate with advancing age, but extends the finding to centenarians. As a result of this activity, participants will be able to: (1) describe the frequency of disfluency breaks and the types of disfluencies exhibited by centenarian speakers, (2) describe the mean and range of speaking rates in centenarians, and (3) compare the present findings for centenarians to the fluency and speaking rate characteristics reported in the literature.

    Led by the federal government, the payers of health care are enacting policies designed to base provider reimbursement on the quality of care they render. This study evaluated and compared patient experiences and satisfaction with nasal decolonization with either nasal povidone-iodine (PI) or nasal mupirocin ointment (MO). A total of 1903 patients were randomized to undergo preoperative nasal decolonization with either nasal MO or PI solution. All randomized patients were also given 2% chlorhexidine gluconate topical wipes. Patients were interviewed prior to discharge to assess adverse events and patient experience with their assigned preoperative antiseptic protocol. Of the 1903 randomized patients, 1679 (88.1%) were interviewed prior to discharge. Of patients receiving PI, 3.4% reported an unpleasant or very unpleasant experience, compared with 38.8% of those using nasal MO (P.05). Being recruited as an active participant in surgical site infection prevention was a positive experience for 87.2% of MO patients and 86.3% of PI patients (P=.652). Those assigned to receive PI solution preoperatively reported significantly fewer adverse events than the nasal MO group (P<.01). Preoperative nasal decolonization with either nasal PI or MO was considered somewhat or very helpful by more than two-thirds of patients. Copyright 2014, SLACK Incorporated.

    Changes of nasal dimensions can influence the air-conditioning capacity of the nose because of alterations of airflow patterns. The goal of this study was to evaluate the correlation between intranasal temperature and humidity values and nasal dimensions, assessed by means of acoustic rhinometry. Eighty healthy volunteers (40 men and 40 women; median age, 51 years; range, 20-84 years) were enrolled in the study. In total, 160 nasal cavities were examined. All volunteers underwent a standardized acoustic rhinometry. Additionally, intranasal air temperature and humidity measurements at defined intranasal detection sites within the anterior nasal segment were performed. There was no statistically significant difference between the right and left side of the nose regarding air temperature, absolute humidity, and acoustic rhinometric values. A negative correlation was established between the rhinometric nasal volumes/minimal cross-sectional areas and air temperature and absolute humidity values at the three intranasal detection sites. According to our results, nasal volumes and cross- sectional areas relevantly influence nasal air conditioning. A healthy nasal cavity with smaller volumes and cross-sectional areas seems to present a more effective air-conditioning function than a too "wide" open nose because of changes in airflow patterns. This observation should be considered as a limitation for overly extensive nasal surgery especially of the turbinates.

    Full Text Available The recent advancement of nasal drug delivery systems has increased enormously and is gaining significant importance. Intranasal therapy has been an accepted form of treatment in the Ayurvedic system of Indian Medicine. The non-invasive delivery of nasal drug delivery systems made to exploit for the development of successful treatment. The advantages, disadvantages, mechanism of action and application of nasal drug delivery system in local delivery, systematic delivery, nasal vaccines and CNS delivery are explained lucidly. The relevant aspects of biological, physicochemical and pharmaceutical factors of nasal cavity that must be considered during the process of discovery and development of new drugs for nasal delivery as well as in their incorporation into appropriate nasal pharmaceutical formulations are also discussed. Nasal route is more suitable for those drugs which cannot be administered orally due to gastric degradation or hepatic first pass metabolism of the drug. Intranasal drug delivery is found much promising route for administration of peptides and protein drugs. Much has been investigated and much more are to be investigated for the recent advancement of nasal drug delivery systems.

    The aim of this study is to investigate nasal and paranasal signs and symptoms of the primary Sjogren`s syndrome patients and compare them with healthy controls. Seventy-seven (7 M, 70 F) primary Sjogren`s syndrome patients and 77 healthy controls were included in the study. Anterior rhinoscopy, nasal endoscopy, 5 component smell discrimination test, nasal clearance analysis with saccharin test and electrorhinomanometer were performed. Nasal crusting was present in 31 and 24 individuals in patient and control groups, respectively. Sinusitis was present in 2 and 1 individuals in patient and control groups, respectively. Nasal polyposis was present in 7 and 1 individuals in patient and control groups, respectively. These differences were not statistically different. Although there were some findings in a few patients, nasal findings were insignificant and mild even in patients with severe oral or ocular findings. Rhinomanometry, nasal clearance determination or smell discrimination tests have very little value in the diagnosis or management of primary Sjogren`s syndrome. Nasal polyposis was higher in the patient group, though it did not reach a significant level. Nasal glandular involvement is mild and insignificant in primary Sjogren`s syndrome.

    Speakers frequently have specific intentions that they want others to recognize (Grice, 1957). These specific intentions can be viewed as speech acts (Searle, 1969), and I argue that they play a role in long-term memory for conversation utterances. Five experiments were conducted to examine this idea. Participants in all experiments read scenarios ending with either a target utterance that performed a specific speech act (brag, beg, etc.) or a carefully matched control. Participants were more likely to falsely recall and recognize speech act verbs after having read the speech act version than after having read the control version, and the speech act verbs served as better recall cues for the speech act utterances than for the controls. Experiment 5 documented individual differences in the encoding of speech act verbs. The results suggest that people recognize and retain the actions that people perform with their utterances and that this is one of the organizing principles of conversation memory.

    Kunche, Prajna

    2016-01-01

    This book serves as a basic reference for those interested in the application of metaheuristics to speech enhancement. The major goal of the book is to explain the basic concepts of optimization methods and their use in heuristic optimization in speech enhancement to scientists, practicing engineers, and academic researchers in speech processing. The authors discuss why it has been a challenging problem for researchers to develop new enhancement algorithms that aid in the quality and intelligibility of degraded speech. They present powerful optimization methods to speech enhancement that can help to solve the noise reduction problems. Readers will be able to understand the fundamentals of speech processing as well as the optimization techniques, how the speech enhancement algorithms are implemented by utilizing optimization methods, and will be given the tools to develop new algorithms. The authors also provide a comprehensive literature survey regarding the topic.

    The current study was undertaken to investigate the impact of speech motor issues on the speech intelligibility of children with moderate to severe speech sound disorders (SSD) within the context of the PROMPT intervention approach. The word-level Children's Speech Intelligibility Measure (CSIM), the sentence-level Beginner's Intelligibility Test (BIT) and tests of speech motor control and articulation proficiency were administered to 12 children (3:11 to 6:7 years) before and after PROMPT therapy. PROMPT treatment was provided for 45 min twice a week for 8 weeks. Twenty-four naïve adult listeners aged 22-46 years judged the intelligibility of the words and sentences. For CSIM, each time a recorded word was played to the listeners they were asked to look at a list of 12 words (multiple-choice format) and circle the word while for BIT sentences, the listeners were asked to write down everything they heard. Words correctly circled (CSIM) or transcribed (BIT) were averaged across three naïve judges to calculate percentage speech intelligibility. Speech intelligibility at both the word and sentence level was significantly correlated with speech motor control, but not articulatory proficiency. Further, the severity of speech motor planning and sequencing issues may potentially be a limiting factor in connected speech intelligibility and highlights the need to target these issues early and directly in treatment. The reader will be able to: (1) outline the advantages and disadvantages of using word- and sentence-level speech intelligibility tests; (2) describe the impact of speech motor control and articulatory proficiency on speech intelligibility; and (3) describe how speech motor control and speech intelligibility data may provide critical information to aid treatment planning.

    Full Text Available Background and Aim : Nasalization of a vowel refers to the addition of nasal resonance to the vocal tract transfer function. Also, vowel nasalization occurs because of coarticulation. Coupling of the nasal resonating space to the oropharyngeal cavity alters the vocal tract formants in complex ways. The purpose of this study was to investigate the effect of nasalization on /a/ vowel formants in before and after nasal consonant.Methods: In current cross-sectional study, voice samples of 60 normal children ranging the age of four-nine years were investigated. Participants were asked to repeat / ʔ ama/ three times and vowel /a/ after presentation of an auditory model. Then, obtained samples were analyzed using Praat 5.3.13 . Average of F0, F1, F2 and F3 were calculated for /a/ comes before and after /m/ in production of / ʔ ama/ over three trials.Results: There were statistically significant differences of F1, F2 and F3 between / a/ which proceeds nasal consonant and /a/ follows nasal consonant , the before nasal consonant /a/ versus single /a/ and the after nasal consonant /a/ versus single /a/ (p=0.001 for all.Conclusion : F1, F2 and F3 in /a/ before nasal consonant affected by anticipatory nasal coarticulation and in /a/ after nasal consonant affected by carry-over nasal coarticulation . This study showed nasal coarticulation and nasalization result in decreasing F1, F2 and F3 in /a/ vowel.

Systematic study of congestion has largely considered it as a component of a disease state. Conditions associated with congestion include nasal polyposis, obstructive sleep apnea, and anatomic variation; however, most information on the burden of congestion comes from studies of allergic rhinitis and rhinosinusitis, diseases of which congestion is the major symptom. Congestion can be caused by other rhinologic conditions, such as non-allergic rhinitis, viral or bacterial rhinitis, and vasomotor rhinitis. Allergic rhinitis affects as much as one quarter of the population worldwide and imposes a significant economic burden. Additionally, allergic rhinitis significantly impairs quality of life; congestion causes allergic rhinitis sufferers decreased daytime productivity at work or school and reduces night-time sleep time and quality. Annually, rhinosinusitis affects tens of millions of Americans and leads to approximately $6 billion in overall health care expenditures; it has been found to be one of the most costly physical conditions for US employers. Given the high prevalence and significant social and economic burden of nasal congestion, this symptom should be a key consideration in treating patients with rhinologic disease, and there continues to be a significant unmet medical need for effective treatment options for this condition.Keywords: allergic rhinitis, congestion, epidemiology, obstruction, rhinosinusitis

    2017-03-01

    Nasal tip mechanical stability is important for functional and cosmetic nasal airway surgery. Palpation of the nasal tip provides information on tip strength to the surgeon, though it is a purely subjective assessment. Providing a means to simulate nasal tip deformation with a validated model can offer a more objective approach in understanding the mechanics and nuances of the nasal tip support and eventual nasal mechanics as a whole. Herein we present validation of a finite element (FE) model of the nose using physical measurements recorded using an ABS plastic-silicone nasal phantom. Three-dimensional photogrammetry was used to capture the geometry of the phantom at rest and while under steady state load. The silicone used to make the phantom was mechanically tested and characterized using a linear elastic constitutive model. Surface point clouds of the silicone and FE model were compared for both the loaded and unloaded state. The average Hausdorff distance between actual measurements and FE simulations across the nose were 0.39 ± 1.04 mm and deviated up to 2 mm at the outermost boundaries of the model. FE simulation and measurements were in near complete agreement in the immediate vicinity of the nasal tip with millimeter accuracy. We have demonstrated validation of a two-component nasal FE model, which could be used to model more complex modes of deformation where direct measurement may be challenging. This is the first step in developing a nasal model to simulate nasal mechanics and ultimately the interaction between geometry and airflow.

The congenital condition is caused by a neural-tube defect attributable to an interaction among several genes and environmental factors. Anterior encephalocele is a rare entity and its incidence varies depending on the geographic area. We report the case of a newborn with a tumour protruding through the fronto-nasal region with a central pedunculated polypoid formation, in addition to the presence of bilateral cleft lip and palate. Surgical treatment was decided after consulting the Neurosurgery Department. This case report is interesting due to the rarity of this entity.

  13. Indexing cortical entrainment to natural speech at the phonemic level: Methodological considerations for applied research.

    Di Liberto, Giovanni M; Lalor, Edmund C

    2017-02-27

    Speech is central to human life. As such, any delay or impairment in receptive speech processing can have a profoundly negative impact on the social and professional life of a person. Thus, being able to assess the integrity of speech processing in different populations is an important goal. Current standardized assessment is mostly based on psychometric measures that do not capture the full extent of a person's speech processing abilities and that are difficult to administer in some subjects groups. A potential alternative to these tests would be to derive "direct", objective measures of speech processing from cortical activity. One such approach was recently introduced and showed that it is possible to use electroencephalography (EEG) to index cortical processing at the level of phonemes from responses to continuous natural speech. However, a large amount of data was required for such analyses. This limits the usefulness of this approach for assessing speech processing in particular cohorts for whom data collection is difficult. Here, we used EEG data from 10 subjects to assess whether measures reflecting phoneme-level processing could be reliably obtained using only 10 min of recording time from each subject. This was done successfully using a generic modeling approach wherein the data from a training group composed of 9 subjects were combined to derive robust predictions of the EEG signal for new subjects. This allowed the derivation of indices of cortical activity at the level of phonemes and the disambiguation of responses to specific phonetic features (e.g., stop, plosive, and nasal consonants) with limited data. This objective approach has the potential to complement psychometric measures of speech processing in a wide variety of subjects.

  14. Sensorimotor Interactions in Speech Learning

    Douglas M Shiller

    2011-10-01

    Full Text Available Auditory input is essential for normal speech development and plays a key role in speech production throughout the life span. In traditional models, auditory input plays two critical roles: 1 establishing the acoustic correlates of speech sounds that serve, in part, as the targets of speech production, and 2 as a source of feedback about a talker's own speech outcomes. This talk will focus on both of these roles, describing a series of studies that examine the capacity of children and adults to adapt to real-time manipulations of auditory feedback during speech production. In one study, we examined sensory and motor adaptation to a manipulation of auditory feedback during production of the fricative “s”. In contrast to prior accounts, adaptive changes were observed not only in speech motor output but also in subjects' perception of the sound. In a second study, speech adaptation was examined following a period of auditory–perceptual training targeting the perception of vowels. The perceptual training was found to systematically improve subjects' motor adaptation response to altered auditory feedback during speech production. The results of both studies support the idea that perceptual and motor processes are tightly coupled in speech production learning, and that the degree and nature of this coupling may change with development.

    Full Text Available Background: Nasal continuous positive airway pressure (NCPAP is an effective method of ventilation in newborns with respiratory distress syndrome (RDS. Using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive NCPAP. This study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal skin integrity in preterm newborns who receive NCPAP.Materials and Methods: A Randomized Controlled Trial was used to conduct the study. A cohort of 110 preterm newborns with a gestational age (GA of 25 to 36 weeks, receiving nasal continuous positive airway pressure (NCPAP for RDS in the neonatal intensive care unit of a university teaching hospital were selected to perform the study. They were randomly assigned to a protocolized nasal skin care (group A or to a group receiving the routine care (group B. Nasal skin integrity of the preterm neonates, were measured on a daily basis for 10 days using the Neonatal Skin Condition Scale (NSCS 24 hours after placement of NCPAPs in both groups.Results: Each intervention and control group included 55 neonates. 65.50% of neonates in the control group and 47.30% of neonates in the intervention group were male. Repeated measures analysis showed thatNSCS scores were significantly lower in intervention group receiving nasal skin care in accordance with the protocol than the control group receiving the routine nasal skin care (P=0.000. Conclusion: In this study, the protocolized care reduced nasal skin breakdown in the preterm newborns receiving NCPAP. Therefore, it can be used as an effective method in nasal skin care in neonates who are treated by NCPAP.

    External nasal splinting is performed routinely after nasal bone fracture reductions, osteotomies, and rhinoplasties. Materials commonly used include plaster of Paris (POP), thermoplastic splints, self-adhesive padded aluminium splints, and Orthoplast, among many others. The disadvantages of these materials are described in this paper, and polyvinyl siloxane is recommended as an effective and more readily available alternative material to counter these pitfalls.

    Solcoseryl is a biological agent, which accelerates the healing tissue procedure. This influence was studied during the nasal septum surgery. In 25 patients the postoperational nasal plug was inserted with the Solcoseryl and in 10 (control) with the paraffin. The cytologic verifications were performed before and after the surgery. In the solcoseryl group the mucosa regeneration procedure was accelerated and the inflammation reduced.

    The nasal mucosa, the first tissue of contact for inhaled xenobiotics, possesses substantial enobiotic-metabolizing capacti. Enzymes of the nasal cavity may metabolize xenobiotics to innocuous, more water-soluble compounds that are eliminated from the body, or they may bioactivate them to toxic metabolites. These toxic metabolites may find to cellular macromolecules in the nasal cavity or be transported to other parts of the body where they may react. Nasal carcinogenesis in rodents often results from bioactivation of xenobiotics. The increased incidences of nasal tumors associated with certain occupations suggest that xenobiotic bioactivation may be important in human nasal cancer etiology, as well. The increasing popularity of the nose as a route of drug administration makes information concerning nasal drug metabolism and disposition vital to accomplish therapeutic goals. For these reasons, the study of xenobiotic-met abolizing capacity of the nasal cavity is an important area of health-related research. In the present study, we have confirmed the presence of CYP2A6 mRNA in human respiratory mucosa.

    Turbinectomy, although a common procedure, is often accused of having a negative impact in all nasal functions. This study is the first in vivo study that evaluates objectively the effect of partial turbinectomy on nasal air-conditioning capacity. In total, 57 patients with prior partial inferior turbinectomy and 28 healthy controls were examined. Intranasal temperature and humidity values were measured at the level of the head of inferior and middle turbinate. Nasal patency was evaluated by means of acoustic rhinometry. The clinical assessment was completed with nasal endoscopy and the Nasal Obstruction Symptom Evaluation questionnaire for subjective evaluation of nasal patency. Significant changes of temperature were found in both detection sites with 13% reduced heating capacity of the air at the level of the inferior and 19% at the level of the middle turbinate, respectively. No similar results were found for humidity measurements. No correlations were found between air-conditioning values and acoustic rhinometry results for both study groups. Nasal endoscopy revealed normal healing in all patients. No major complications were reported by the patients. Their subjective ratings of nasal obstruction were similar to healthy controls. Partial turbinectomy seems to have a negative impact on intranasal air heating but not to humidification. This effect has no impact on clinical condition and subjective perception of surgical outcome.

    We describe the approach to linguistic variation taken by the Motorola speech synthesizer. A pan-dialectal pronunciation dictionary is described, which serves as the training data for a neural network based letter-to-sound converter. Subsequent to dictionary retrieval or letter-to-sound generation, pronunciations are submitted a neural network based postlexical module. The postlexical module has been trained on aligned dictionary pronunciations and hand-labeled narrow phonetic transcriptions. This architecture permits the learning of individual postlexical variation, and can be retrained for each speaker whose voice is being modeled for synthesis. Learning variation in this way can result in greater naturalness for the synthetic speech that is produced by the system.

    Background: Recovery of Bell`s phenomenon after levator resection is unpredicatable. Delayed recovery can result in vision threatening corneal complications. Aim: To study the variability of Bell’s phenomenon and time taken for its recovery following levator resection for blepharoptosis and to correlate it with the amount of resection. Methods: A prospective observational study was conducted on 32 eyes of 32 patients diagnosed as unilateral simple congenital blepharoptosis who underwent levator resection at a tertiary care center between July 2013 and May 2015. Patients were followed up for 5 months and correction of ptosis, type of Bell`s, duration of Bell`s recovery and complications were noted. Results: The study group ranged from 16-25 years with 15:17 male: female ratio. There were 9 mild, 16 moderate and 7 severe ptosis. Satisfactory correction was achieved in all cases. Good Bell`s recovery occurred in 13 eyes on first post-op day, in 2-14 days in 19 eyes and 28 days in 1 eye. Inverse Bell`s was noted along with lid oedema and ecchymosis in 2 patients. Large resections (23-26mm) were associated with poor Bell`s on the first postoperative day (p=0.027, Fisher`s exact test). However, the duration required for recovery of Bell`s phenomenon did not show any significant difference with the amount of resection. (p=0.248, Mann Whitney test). Larger resections resulted in greater lagophthalmos (correlation=0.830, p<0.0001). Patients with recovery of Bell`s delayed for more than 7 days were associated with greater number of complications (p=0.001 Fisher`s Exact Test). Conclusion: Close monitoring for Bell`s recovery is required following levator resection. PMID:28584563

    The aim of this multicenter clinical field study was to assess the benefits of the new Freedom 24 sound processor for cochlear implant (CI) users implanted with the Nucleus 24 cochlear implant system. The study included 48 postlingually profoundly deaf experienced CI users who demonstrated speech comprehension performance with their current speech processor on the Oldenburg sentence test (OLSA) in quiet conditions of at least 80% correct scores and who were able to perform adaptive speech threshold testing using the OLSA in noisy conditions. Following baseline measures of speech comprehension performance with their current speech processor, subjects were upgraded to the Freedom 24 speech processor. After a take-home trial period of at least 2 weeks, subject performance was evaluated by measuring the speech reception threshold with the Freiburg multisyllabic word test and speech intelligibility with the Freiburg monosyllabic word test at 50 dB and 70 dB in the sound field. The results demonstrated highly significant benefits for speech comprehension with the new speech processor. Significant benefits for speech comprehension were also demonstrated with the new speech processor when tested in competing background noise.In contrast, use of the Abbreviated Profile of Hearing Aid Benefit (APHAB) did not prove to be a suitably sensitive assessment tool for comparative subjective self-assessment of hearing benefits with each processor. Use of the preprocessing algorithm known as adaptive dynamic range optimization (ADRO) in the Freedom 24 led to additional improvements over the standard upgrade map for speech comprehension in quiet and showed equivalent performance in noise. Through use of the preprocessing beam-forming algorithm BEAM, subjects demonstrated a highly significant improved signal-to-noise ratio for speech comprehension thresholds (i.e., signal-to-noise ratio for 50% speech comprehension scores) when tested with an adaptive procedure using the Oldenburg

    Event-related potentials (ERPs) were recorded during a picture naming task of simple and complex words in children with typical speech and with childhood apraxia of speech (CAS). Results reveal reduced amplitude prior to speaking complex (multisyllabic) words relative to simple (monosyllabic) words for the CAS group over the right hemisphere during a time window thought to reflect phonological encoding of word forms. Group differences were also observed prior to production of spoken tokens regardless of word complexity during a time window just prior to speech onset (thought to reflect motor planning/programming). Results suggest differences in pre-speech neurolinguistic processes.

    Newman, S P; Morén, P F; Clarke, S W

    1987-02-01

    The intranasal distribution of aerosol from a metered dose inhaler has been assessed using a radiotracer technique. Inhalers were prepared by adding 99Tcm-labelled Teflon particles (simulating the drug particles) to chlorofluorocarbon propellants, and scans of the head (and chest) taken with a gamma camera. Ten healthy subjects (age range 19-29 years) each performed two radioaerosol studies with the inhaler held in two different ways: either in a single position (vial pointing upwards) or in two positions (vial pointing upwards and then tilted by 30 degrees in the sagittal plane). The vast majority of the dose (82.5 +/- 2.8 (mean +/- SEM) per cent and 80.7 +/- 3.1 per cent respectively for one-position and two-position studies) was deposited on a single localized area in the anterior one-third of the nose, the initial distribution pattern being identical for each study. No significant radioaerosol was detected in the lungs. Only 18.0 +/- 4.7 per cent and 15.4 +/- 4.1 per cent of the dose had been removed by mucociliary action after 30 minutes, and it is probable that the remainder had not penetrated initially beyond the vestibule. Since the deposition pattern was highly localized and more than half the dose probably failed to reach the turbinates it is possible that the overall effect of nasal MDIs is suboptimal for the treatment of generalized nasal disorders.

    Full Text Available We report a rare case of nasal glial heterotopia in an adult. After the surgery, frontal lobe cerebral hemorrhage developed. A 58-year-old man had unilateral nasal obstruction that progressed for one year. He had been treated for hypertension, chronic heart failure, and cerebral infarction with aspirin and warfarin. A computed tomography scan showed that the tumor occupied the right nasal cavity and the sinuses with small defect in the cribriform plate. The tumor was removed totally with endoscopy. After the operation, the patient developed convulsions and frontal lobe cerebral hemorrhage. The hemorrhage site was located near a defect in the cribriform plate. Nasal glial heterotopia is a rare developmental abnormality, particularly rare in adult. Only few cases were reported. We could not find any report of adult nasal glial heterotopias that developed cerebral hemorrhage as a complication of the surgery.

    Full Text Available O objetivo deste artigo é mostrar que o português possui dois processos de nasalização que, em níveis fonológicos separados, lexical e pós-lexical, originam, respectivamente, o ditongo e a vogal nasal. Na formação do ditongo, o efeito da estabilidade é o ponto essencial como é a assimilação para a vogal nasal.The aim of this paper is to show that Portuguese has two processes of nasalization, operantig in separate levels, the lexical one that originates the diphthong and the postlexical that originates the nasal vowel. In the formation of the diphthong, the stability effect, a local condition, is the fundamental point as the assimilation is, as spreading, for the nasal vowel.

    Autism is referred to as cerebral lateralization abnormality. In this study, the possible relationships among handedness, eyedness and nasal cycle in autism have been investigated. Thirty-seven children with autism and 20 controls were included in the study. The patient group included 27 boys and 10 girls who ranged in age from 5 to 20 years. For hand preference, hand used to write and throw a ball was accepted as dominant hand. For eye preference or dominance, eye used to look through keyhole of a door was accepted as dominant eye. Nasal dominance was assessed by a method of measuring the nasal airflow. The rates of left-handedness and left-eyedness were higher in children with autism compared to normal populations. A majority of children with autism had left nasal dominance. Autism and early language impairment may be associated with left handedness, eyedness and nasal dominance.

    The clinical features of localized nasal rosacea have not been described in detail. This study was designed to analyze the subtypes and severity of localized nasal rosacea. Our present study included 30 patients with localized nasal rosacea. The erythematotelangiectatic subtype (13/30, 43.3%) was the most common type, followed by the phymatous subtype (9/30, 30%). The duration of rosacea was shorter and the severity of localized nasal rosacea was lower in the erythematotelangiectatic subtype cases compared with the patients with mixed or phymatous subtypes. Almost all of the papulopustular eruptions or phymatous lesions were associated with erythematotelangiectatic lesions. These findings suggest that the erythematotelangiectatic subtype may be considered the initial phase of localized nasal rosacea.

    To assess speech outcomes after anterior maxillary distraction (AMD) in patients with cleft-related maxillary hypoplasia. Fifty-eight patients at least 10 years old with cleft-related maxillary hypoplasia were included in this study irrespective of gender, type of cleft lip and palate, and amount of required advancement. AMD was carried out in all patients using a tooth-borne palatal distractor by a single oral and maxillofacial surgeon. Perceptual speech assessment was performed by 2 speech language pathologists preoperatively, before placement of the distractor device, and 6 months postoperatively using the scoring system of Perkins et al (Plast Reconstr Surg 116:72, 2005); the system evaluates velopharyngeal insufficiency (VPI), resonance, nasal air emission, articulation errors, and intelligibility. The data obtained were tabulated and subjected to statistical analysis using Wilcoxon signed rank test. A P value less than .05 was considered significant. Eight patients were lost to follow-up. At 6-month follow-up, improvements of 62% (n = 31), 64% (n = 32), 50% (n = 25), 68% (n = 34), and 70% (n = 35) in VPI, resonance, nasal air emission, articulation, and intelligibility, respectively, were observed, with worsening of all parameters in 1 patient (2%). The results for all tested parameters were highly significant (P ≤ .001). AMD offers a substantial improvement in speech for all 5 parameters of perceptual speech assessment.

    Full Text Available Introduction: This contribution presents the results of a research focused on speech therapy in kindergartens. This research was realized in Zlín Region. It explains how speech therapy prevention is realized in kindergartens, determines the educational qualifications of teachers for this activity and verifies the quality of the applied methodologies in the daily program of kindergartens. Methods: The empirical part of the study was conducted through a qualitative research. For data collection, we used participant observation. We analyzed the research data and presented them verbally, using frequency tables and graphs, which were subsequently interpreted. Results: In this research, 71% of the teachers completed a course of speech therapy prevention, 28% of the teachers received pedagogical training and just 1% of the teachers are clinical speech pathologists. In spite of this, the research data show that, in most of kindergartens, the aim of speech therapy prevention is performed in order to correct deficiencies in speech and voice. The content of speech therapy prevention is implemented in this direction. Discussion: Awareness of the teachers’/parents’ regarding speech therapy prevention in kindergartens. Limitations: This research was implemented in autumn of 2016 in Zlín Region. Research data cannot be generalized to the entire population. We have the ambition to expand this research to other regions next year. Conclusions: Results show that both forms of speech therapy prevention - individual and group - are used. It is also often a combination of both. The aim of the individual forms is, in most cases, to prepare a child for cooperation during voice correction. The research also confirmed that most teachers do not have sufficient education in speech therapy. Most of them completed a course of speech therapy as primary prevention educators. The results also show that teachers spend a lot of time by speech therapy prevention in

    1997-01-01

    Full Text Available Although there is wide variation in the prevalence of nasal allergies internationally, the extent to which this is due to variation in etiological factors is not known. The purpose of the present study was to define the relative importance of atopy and other risk factors for nasal allergies, including hayfever, among young adults in Melbourne. The subjects were participants in the second phase of the European Community Respiratory Health Survey; 876 adults between 20 and 45 years of age completed a detailed respiratory questionnaire, 745 had skin prick testing with common aeroallergens and 675 underwent methacholine challenge. Total and allergen-specific IgE levels were measured in 701 and 693 subjects by radioimmunoassay and RAST, respectively. Nasal allergies, including hayfever, were reported by 47.5% of randomly selected participants. Females, non- smokers, subjects with a family history of allergies, those with current asthma, a history of eczema and nasal symptoms induced by dust, pollen or food were significantly more likely to have nasal allergies. Oral antihistamines had been used by 45.7% of those reporting nasal allergies and 12.4% had received allergen immunotherapy. The risk of nasal allergies, including hayfever, was increased 6.1-fold by atopy, particularly by positive skin tests to outdoor allergens such as Birch, Timothy grass, plantain, olive, Cladosporium and Rye grass pollen. Total serum IgE was significantly higher in subjects reporting nasal allergies than in those who did not report such allergies. There were significant trends in the prevalence of nasal allergies with increasing titers of specific IgE directed against all allergens tested. In conclusion, the significant independent risk factors for nasal allergies, including hayfever, in young adults were atopy, particularly sensitization to Timothy grass, house dust mites and plantain, current asthma, not smoking, a history of eczema and female gender.

Recent studies suggested that the allergen load presents seasonal modifications, giving rise to seasonal variation in nasal inflammation and symptoms. The aim of this study was to evaluate by nasal cytology whether nasal inflammation in mite-allergic patients changes with the seasons of the year. Methods: The study included 16 patients (seven males and nine females, mean age 38.1 years with persistent AR caused by monosensitization to HDMs. Nasal cytology was performed in all patients once monthly for 1 year. Results: Nasal cytology showed that the cells most commonly detected in the nasal mucosa were neutrophils. During the period from October to April, a peak in the number of neutrophils and also the presence of significant numbers of eosinophils, mast cells, and lymphocytes/plasma cells were found, which shows the occurrence of more intense inflammation during these months. Conclusion: Nasal cytology provides useful data in detecting nasal inflammation and its association with the clinical stage of AR. The seasonal variations in nasal cytology are likely to be induced by the fluctuations in the HDM allergen that have been uncovered in recent investigations. Keywords: allergens

In two cases, the bleeding was resolved in this way, instead eight cases needed of subperiosteal cauterization of sphenopalatine artery by Dessi bipolar forceps (MicroFrance(®)). 4 of these 8 patients evidenced a remarkable bleeding removing nasal packing (Hb before-nasal packing = 15 ± 0.69 versus Hb after-nasal packing = 13.3 ± 0.81; t student = 2.94; p value = 0.025). These four patients showed a deviation of the nasal septum ipsilateral to epistaxis, and according our experience, a traumatism of sphenopalatine area can be caused by Merocel(®) nasal packing in this condition. During follow-up, no recurrences of nasal bleeding have been observed in such patients. Nasal packing must be considered if posterior epistaxis is severe, but always taking into account the specific anatomy of patient and in particular septal spurs that can further compromise sphenopalatine artery. In our experience, the endoscopic endonasal cauterization of the sphenopalatine branches represented a safe and effective procedure.

    In this study, the effects of nasal drug delivery device and the spray nozzle orientation on sprayed droplets deposition in a realistic human nasal cavity were numerically studied. Prior to performing the numerical investigation, an in-house designed automated actuation system representing mean adults actuation force was developed to produce realistic spray plume. Then, the spray plume development was filmed by high speed photography system, and spray characteristics such as spray cone angle, break-up length, and average droplet velocity were obtained through off-line image analysis. Continuing studies utilizing those experimental data as boundary conditions were applied in the following numerical spray simulations using a commercially available nasal spray device, which was inserted into a realistic adult nasal passage with external facial features. Through varying the particle releasing direction, the deposition fractions of selected particle sizes on the main nasal passage for targeted drug delivery were compared. The results demonstrated that the middle spray direction showed superior spray efficiency compared with upper or lower directions, and the 10µm agents were the most suitable particle size as the majority of sprayed agents can be delivered to the targeted area, the main passage. This study elaborates a comprehensive approach to better understand nasal spray mechanism and evaluate its performance for existing nasal delivery practices. Results of this study can assist the pharmaceutical industry to improve the current design of nasal drug delivery device and ultimately benefit more patients through optimized medications delivery.

    An in vitro human nasal model was developed as a tool to study the local tolerability of nasal powder forms using excised nasal mucosa in a diffusion chamber. The suitability of this model was tested using Sandostatin (SMS) an octapeptide analog of somatostatin, as a reference drug enhanced by Avicel (microcrystalline cellulose) or lactose (100 mesh). The standard nasal spray vehicle was taken as a harmless control and 1% chenodeoxycholate (CDC) as a harmful control in terms of local tolerability. The extent of peptide permeation was determined by measuring SMS concentration in the receiving chamber. The labeling of SMS was detected by immunoperoxidase staining on cross sections. The local tolerability for all tested forms was assessed by histopathological examination and scanning electron microscopy. The apparent permeation coefficient allowed us to rank the absorption of the tested drug forms as Avicel > spray = lactose > 1%CDC. For all formulations, SMS was detected in the epithelium. No changes of the nasal mucosa could be observed with Avicel, lactose or nasal spray vehicle in the presence or absence of SMS. 1%CDC with or without drug showed an immediate destruction of the nasal epithelium. The validation of this in vitro model using human nasal mucosa will be further discussed as a tool for assessing the local tolerability of intranasally applied test substances.

    Two options exist for restoring structure and function after maxillectomy. Prosthodontic rehabilitation requires that an obturator be constructed to address the oronasal communication that exists after resection of the maxilla. Surgical reconstruction of the defect is another option, often accomplished with the use of bone-containing flaps. To determine whether prosthetic rehabilitation or surgical reconstruction of the maxilla provides better speech and facial aesthetic outcomes after maxillectomy. Fifty-nine patients in three groups were included: 23 patients with maxillary obturators, 16 patients with maxillary reconstruction, and 20 patients without any maxillary defects but who were diagnosed with nasopharyngeal cancer and who served as a control group. Using digitized photographs, facial attractiveness was rated on a 10-point scale by eight judges who were blinded to treatment group. Speech outcomes included nasalance, velopharyngeal orifice opening, and speech intelligibility. There were no significant between-group differences found for facial attractiveness ratings. However, patients in either group who had involvement of the orbital rim or the orbital rim and zygoma were rated as significantly less attractive than those without such involvement. With respect to speech outcomes, the control group (ie, nasopharynx) had smaller velopharyngeal orifice areas than the obturator group; however, this was not clinically significant as scores in both groups were within normal limits. In conclusion, this study found no differences between surgical reconstruction or prosthodontic intervention of maxillary defects when facial attractiveness was assessed by naive raters and speech outcomes were assessed using objective measurements.

    2009-12-01

    Assistive speech-enabled systems are proposed to help both French and English speaking persons with various speech disorders. The proposed assistive systems use automatic speech recognition (ASR) and speech synthesis in order to enhance the quality of communication. These systems aim at improving the intelligibility of pathologic speech making it as natural as possible and close to the original voice of the speaker. The resynthesized utterances use new basic units, a new concatenating algorithm and a grafting technique to correct the poorly pronounced phonemes. The ASR responses are uttered by the new speech synthesis system in order to convey an intelligible message to listeners. Experiments involving four American speakers with severe dysarthria and two Acadian French speakers with sound substitution disorders (SSDs) are carried out to demonstrate the efficiency of the proposed methods. An improvement of the Perceptual Evaluation of the Speech Quality (PESQ) value of 5% and more than 20% is achieved by the speech synthesis systems that deal with SSD and dysarthria, respectively.

    Full Text Available Being a component of socio-cultural interaction discourse constitutes a sophisticated cohesion of language form, meaning and performance, i.e. communicative event or act. Cohesion with event and performance let us treat discourse as a certain lifeform, appealing both to communicative interaction and pragmatic environment using the methodology of studies of E. Benveniste, M. Foucault, I. Kecskes, J.R. Searle et al. In linguistics and other fields of humanitarian knowledge the notion of discourse facilitates the integration of studies in humanities. Principles of integration, incorporation into broad humanitarian context reveal some topics of discourse-speech act-utterance interaction which leads to substantive solutions of a number of linguistic topics, in particular, that of an utterance. Logicians determine utterance through proposition; linguists - through sentence, while speech act theory does it by means of illocutionary act. Integrated in a discourse or its part, utterance makes up their integral constituents although not unique ones. In relation to speech acts, utterance happens to be the unique definitional domain synchronically modelling and denoting speech act by means of propositional content. The goal of the research is to show the conditions of interaction and correlation of discourse, speech act and utterance as linguistic constructions, reveal some similarities and differences of their characteristics and prove the importance of the constructive role of utterance as a minimal unit of speech production. Discourse-speech act-utterance correlation supports the utterance role of a discrete unit within syntactic continuum, facing both language and speech: still, it belongs exclusively neither to language nor speech, but specifies their interaction in course of speech activity exposing simultaneously its nature of an ‘atom of discourse’ and creating the definitional domain of a speech act.

    Nasal delivery has become a growing area of interest for drug administration as a consequence of several practical advantages, such as ease of administration and non-invasiveness. Moreover, the avoidance of hepatic first-pass metabolism and rapid and efficient absorption across the permeable nasal mucosa offer a promising alternative to other traditional administration routes, such as oral or parenteral delivery. In fact, nasal delivery has been proposed for a number of applications, including local, systemic, direct nose-to-brain and mucosal vaccine delivery. Nanoemulsions, due to their stability, small droplet size and optimal solubilization properties, represent a versatile formulation approach suitable for several administration routes. Nanoemulsions demonstrated great potential in nasal drug delivery, increasing the absorption and the bioavailability of many drugs for systemic and nose-to-brain delivery. Furthermore, they act as an active component, i.e. an adjuvant, in nasal mucosal vaccinations, displaying the ability to induce robust mucosal immunity, high serum antibodies titres and a cellular immune response avoiding inflammatory response. Interestingly, nanoemulsions have not been proposed for the treatment of local ailments of the nose. Despite the promising results in vitro and in vitro, the application of nanoemulsions for nasal delivery in humans appears mainly hindered by the lack of detailed toxicology studies to determine the effect of these formulations on the nasal mucosa and cilia and the lack of extensive clinical trials.

    Full Text Available Over the past few decades, advances in the in situ gel technologies have spurred development in manymedical and biomedical applications including controlled drug delivery. Many novel in situ gel baseddelivery matrices have been designed and fabricated to fulfill the ever increasing needs of thepharmaceutical and medical fields. In situ gelling systems are liquid at room temperature but undergogelation when in contact with body fluids or change in pH. In situ gel forming drug delivery is a type ofmucoadhesive drug delivery system. The formation of gel depends on factors like temperaturemodulation, pH change, presence of ions and ultraviolet irradiation from which the drug gets released ina sustained and controlled manner. Nasal delivery is a promising drug delivery option where commondrug administrations such as intravenous, intramuscular or oral are inapplicable. Recently, it has beenshown that many drugs have better bioavailability by nasal route than the oral route. This has beenattributed to rich vasculature and a highly permeable structure of the nasal mucosa coupled withavoidance of hepatic first-pass elimination, gut wall metabolism and/or destruction in thegastrointestinal tract. The physiology of the nose presents obstacles but offers a promising route for noninvasivesystemic delivery of numerous therapies and debatably drug delivery route to the brain. Thusthis review focuses on nasal drug delivery, various aspects of nasal anatomy and physiology, nasal drugabsorption mechanisms, various nasal drug delivery systems and their applications in drug delivery.

    Full Text Available Introduction Sense of smell is susceptible to various changes, both in physiological and in numerous pathological conditions. Of quantitative disorders of smell, hyposmia and anosmia are quite common, whereas of qualitative disorders parosmia is most frequent. The aim of this paper was to examine impact of bilateral nasal polyposis on olfactory function. Material and methods The research was carried out at the Nose, Ear and Throat Clinic in Novi Sad. It included 80 examinees, 40 (20 male, 20 female with bilateral nasal polyposis, while 40 examinees belonged to the control group (20 male, 20 female without symptoms of nasal polyposes. Fortunato-Niccolini olfactometer was used for this examination. Results and discussion In patients with bilateral nasal polyposis the average perception threshold values for examined odors were 15.50 ccm of odorous air, while in the control group they were 10,20 ccm of odorous air. The average identification threshold values for examined odors in patients with bilateral nasal polyposis were 18.80 ccm of odorous air, while in the control group they were 13.55 ccm of scented air. T-test showed that values of both tresholds were statistically significantly higher (p< 0,01 in patients with bilateral nasal polyposis in relation to the control group. Conclusion Olfactory deficit in patients with bilateral nasal polyposis is explained by difficult or impossible passage of odors into the olfactory region.

    2011-09-01

    Mycobacterium fortuitum, a rapidly growing non-tuberculous atypical mycobacterium, is commonly found in soil and water. This organism generally causes skin, bone, and soft tissue infections following local trauma or surgical procedures, and in immunodeficient patients. The case reported here is, to our knowledge, the first published report of M. fortuitum nasal infection. The authors report the case of a 3-year-old girl with intranasal tumour-like swelling associated with cervical lymph nodes due to M. fortuitum infection. A combination of radical surgical debridement and prolonged therapy with several antimicrobial agents was required to completely eradicate the infection. This case report indicates that non-tuberculous mycobacterial infections should be considered after failure of conventional antibiotic therapy or when classical microbiological tests fail to identify the pathogen responsible for sinonasal and cervical infections.

    Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature.

    2010-07-01

    This clinical randomized controlled trial was performed to compare the effects of distraction osteogenesis (DO) and conventional orthognathic surgery (CO) on velopharyngeal function and speech outcomes in cleft lip and palate (CLP) patients. Twenty-one CLP patients who required maxillary advancement ranging from 4 to 10 mm were recruited and randomly assigned to either CO or DO. Evaluation of resonance and nasal emission, nasoendoscopic velopharyngeal assessment and nasometry were performed preoperatively and at a minimum of two postoperative times: 3-8 months (mean 4 months) and 12-29 months (mean 17 months). Results showed no significant differences in speech and velopharyngeal function changes between the two groups. No correlation was found between the amount of advancement and the outcome measures. It was concluded that DO has no advantage over CO for the purpose of preventing velopharyngeal incompetence and speech disturbance in moderate cleft maxillary advancement.

    Although there is a strong correlation between oral/oro-nasal breathing and apnoea/hypopnoea index in patients with obstructive sleep apnoea and normal nasal resistance at wakefulness, it remains unknown whether the pharmacological prevention of potential nasal obstruction during sleep could decrease oral/oro-nasal breathing and increase nasal breathing and subsequently decrease the apnoea/hypopnoea index. This study evaluated the effect of a combination of a nasal decongestant with corticosteroid on breathing route pattern and apnoea/hypopnoea index. 21 patients with obstructive sleep apnoea (mean apnoea/hypopnoea index 31.1 events per hour) and normal nasal resistance at wakefulness were enrolled in a randomised crossover trial of 1 weeks' treatment with nasal tramazoline and dexamethasone compared with 1 weeks' treatment with nasal placebo. At the start and end of each treatment period, patients underwent nasal resistance measurement and overnight polysomnography with attendant measurement of breathing route pattern. Nasal tramazoline with dexamethasone was associated with decrease in oral/oro-nasal breathing epochs and concomitant increase in nasal breathing epochs, and mean decrease of apnoea/hypopnoea index by 21%. The change in nasal breathing epochs was inversely related to the change in apnoea/hypopnoea index (Rs=0.78; pnasal tramazoline with dexamethasone in OSA patients with normal nasal resistance at wakefulness can restore the preponderance of nasal breathing epochs and modestly improve apnoea/hypopnoea index.

    Healthy humans normally breathe through their nose even though its complex geometry imposes a significantly higher resistance in comparison with mouth breathing. The major functional roles of nasal breathing are defense against infiltrating particles and conditioning of the inspired air to nearly alveolar conditions in order to maintain the internal milieu of the lung. The state-of-the-art of the existing knowledge on nasal air-conditioning will be discussed in this review, including in vivo measurements in humans and computational studies on nasal air-conditioning capacity. Areas where further studies will improve our understanding and may help medical diagnosis and intervention in pathological states will be introduced.

    The recommendation to change breathing patterns from the mouth to the nose can have a significantly positive impact upon the general well being of the individual. We classify nasal and mouth breathing by using an acoustic sensor and intelligent signal processing techniques. The overall purpose is to investigate the possibility of identifying the differences in patterns between nasal and mouth breathing in order to integrate this information into a decision support system which will form the basis of a patient monitoring and motivational feedback system to recommend the change from mouth to nasal breathing.

    Full Text Available Compressing the speech reduces the data storage requirements, leading to reducing the time of transmitting the digitized speech over long-haul links like internet. To obtain best performance in speech compression, wavelet transforms require filters that combine a number of desirable properties, such as orthogonality and symmetry.The MCT bases functions are derived from GHM bases function using 2D linear convolution .The fast computation algorithm methods introduced here added desirable features to the current transform. We further assess the performance of the MCT in speech compression application. This paper discusses the effect of using DWT and MCT (one and two dimension on speech compression. DWT and MCT performances in terms of compression ratio (CR, mean square error (MSE and peak signal to noise ratio (PSNR are assessed. Computer simulation results indicate that the two dimensions MCT offer a better compression ratio, MSE and PSNR than DWT.
