    To investigate the therapeutic effect of alar rotation flap for severe alar retraction. Patients with severely retracted alar underwent ala reconstruction using alar rotation flaps and autogenous cartilage batten grafts. First, costal cartilage was used to reshape the nasal tip and nasal dorsum. Then cartilage patch was used to extend and thicken the retracted alar. Then the alar rotation flap was transferred to correct retracted alar. Fourteen patients with severe alar retraction underwent alar reconstruction with alar rotation flap and alar batten grafts. The alar retraction was corrected in all cases, with improvements functionally and aesthetically. No recurrence of alar retraction was noted. The incision healed with acceptable cosmetic results, with obvious scar in only one patient (one side). The alar rotation flap is an effective and reliable surgical option to correct severe alar retraction. Scar can be kept inconspicuous by precise placement of the incision within the junction of the ala and the nasal dorsum, following principles of the aesthetic nasal subunits.

    The alar rim plays an important role in nasal harmony. Alar rim flaws are common following the initial rhinoplasty. Classification of the deformities helps with diagnosis and successful surgical correction. Diagnosis of the deformity requires careful observation of the computerized or life-sized photographs. Techniques for treatment of these deformities can easily be learned with attention to detail. Copyright © 2016 Elsevier Inc. All rights reserved.

    A postmortem study of craniocerebral traumas of varying severity was done to determine the pattern of injury of the alar ligaments. It was found that in the entire group of patients (n = 30) the alar ligaments were ruptured or suffused with blood 11 times. No close relationship was found between the massive nature of the cranial trauma and the severity of the injury of the alar ligaments. In some cases the alar ligaments were not at all involved even though the skull had suffered extensive osseous lesions, whereas on the other hand the ligaments were injured even though only soft parts had been involved (e.g., haematoma or dehiscent wounds of the scalp). Ruptures of the alar ligaments were typically involved in extended ruptures of the ligamentous apparatus (see Figure 6a involving the ligamentum apicis dentis, ligamentum transversum atlantis, m.atlanto-occipitalis anterior, m.tectoria, m.atlanto-axialis anterior et posterior). In some cases the pattern of injury of the alar ligaments was found to be decisive in enabling reconstruction of the course of the accident. Damage to the alar ligaments near the dens axis represent rotation injuries. On the other hand, insertion tears out of the condyli occipitales must be related to a lateral thrust tendency in indirect fracture of the skull (bursting fracture). Within this overall framework a new mechanism of fracture of the condylus occipitalis is described. As a matter of principle, the alar ligaments can become involved in consequence of rotation, traction and compression of the cranium.

    Nasal widening is commonly associated to maxillary osteotomies, but it is only partially dependent on the amount of skeletal movement. Techniques for controlling lateralization of the ala, including the alar base cinch technique, originally described by Millard, have been well reported by Collins and Epker and later modified by others. In this article, authors report the effect of a new alar cinch suture technique on a sample of 32 patients. PMID:21187940

    The effect of different rhinoplasty maneuvers on alar retraction remains to be elucidated. To determine the etiology and treatment of alar retraction based on a series of specific rhinoplasty maneuvers. Retrospective review of a single surgeon's rhinoplasty digital photo database, examining preoperative alar retraction from January 1, 2002, to December 31, 2005, in 520 patients. Patients with more than 1 mm of alar retraction on preoperative photographs were identified. Postoperative photographs were examined to determine the effect of specific rhinoplasty maneuvers on the position of the alar margin; these maneuvers included cephalic trim, cephalic positioning of the lower lateral cartilage, composite grafts, alar rim grafts, alar batten grafts, and overlay of the lower lateral cartilage. Tertiary care academic health center. Forty-five patients with alar retraction met inclusion criteria, resulting in 63 nasal halves with alar retraction. Intraoperative findings, postoperative results. Forty-seven percent of the patients (n = 21) had prior surgery; 47% also had cephalically positioned lower lateral cartilages. Among patients with less than 4 mm of cartilage width at the outset, 46% of those who received supportive grafts achieved target correction vs only 7% for patients who did not undergo supportive cartilage grafting. In patients who underwent more than 4 mm of cephalic trim, those who received supportive grafts achieved 46% of target correction vs 11% among those who did not. Ninety-five percent of composite grafts, 69% of alar strut grafts, 47% of alar rim grafts, 43% of vertical lobule division, and 12% of alar batten grafts achieved their target correction values. Alar retraction is a highly complex problem. It can be seen de novo and is associated with cephalically positioned lower lateral cartilages. Structurally supportive grafting-including composite grafts, alar strut grafts, alar rim grafts, vertical lobule division, and alar batten grafts

    The purpose of this study was to review the dynamics and frequency of the use of the alar rim graft. The recorded intraoperative information for the purpose of rhinoplasty research was reviewed to investigate the frequency of the use of alar rim grafts. Intraoperative observations were also made while inserting the alar rim graft to identify the changes that occur in the structures that could be influenced by placement of this graft. The data were tabulated in an Excel file and analyzed. Of the 1427 patients who underwent nose reconstruction or rhinoplasty in this study, 565 (39.56 percent) received alar rim grafts. This included 73 primary nose reconstructions, 20 secondary nose reconstructions, two revision nose reconstructions, 304 primary rhinoplasties, 107 secondary rhinoplasties, 43 revision operations following primary rhinoplasties, and seven revision operations following secondary rhinoplasties. However, when 100 more recent consecutive cases were reviewed, 88 percent of primary rhinoplasty patients and 67 percent of secondary rhinoplasty patients received alar rim grafts. The observed dynamic changes after insertion of each graft included (1) correction of the concavity of the ala, (2) caudal advancement of the alar rim, (3) elongation of nostril, and (4) widening of the nostril. The majority of patients who undergo rhinoplasty would benefit from the alar rim graft, and this study demonstrates a steady increase in its use. Placement of an alar rim graft results in elongation of the short nostril, correction of the alar concavity, widening of the nostril, and slight caudal transposition of the alar rim.

    There are four layers of ligamentous stabilizers at the cranio-cervical junction and the second layer is comprised of the apical and paired alar ligaments. The purpose of this study is to establish the tensile strength of the alar ligaments for better understanding the implications that can arise from trauma and other pathologies in the craniocervical region. Nineteen sides from ten fresh frozen adult cadaveric Caucasian heads were used in this study. The specimens were derived from six males and four females, and the age of the cadavers at death ranged from 67 to 90-years-old to measure the tensile strength, a tensile testing machine (M2-200, Mark-10 corporation, USA) was used in this study. The force (N) necessary until failure for all alar ligaments ranged from 87 to 346 N with a mean of 186.9±69.7 N. There was a significant difference when comparing tensile strength between males and females. Further studies will be needed to determine their importance as secondary stabilizers and measure their ability to support similar forces when subject to rotation and lateral bending forces, as well as with flexion-extension.

    2016-08-01

    The purpose of this article is to further explore the techniques available for alar base reduction by a recent review in this topic, focusing in the current advances in the field, in a clear and readable format. Among the numerous techniques available, the management of cases with wide nasal base and alar flaring remains limited to three options: cinching sutures to pull in the alae together; or to use alar base excisions that remove tissue from the alar lobule to decrease flare and from inside the nostril to decrease width; and flap advancement. Surgical modification of the nasal base is not a routine part of rhinoplasty and should be performed in a conservative manner to prevent complications like nasal stenosis. Moreover, this maneuver should always be the last one in rhinoplasty, as alar base modifications cannot be properly assessed until all other steps have been carried out. VIDEO ABSTRACT.

    The nasal ala plays an important role in the aesthetic appearance of the nose. Repairing the nasal alar defect, especially full-thickness alar defect, is one of the difficulties of plastic surgeons. In this article, a new surgical method is introduced about repairing full-thickness alar defect with free auricular composite flaps and local nasal alar rotation and advancement tissue flaps. We retrospectively reviewed 6 patients with a diagnosis of full-thickness alar defect between 2010 and 2013. All of them accepted this new surgical method. The patients were followed up for 6 to 12 months. The method used local nasal alar rotation and advancement tissue flap to form new nasal rim and made the defect of nasal rim shift to alar groove region. After that, we harvested free auricular composite flap to repair the new defect. All patients attained relatively symmetrical nostrils with a natural, smooth, integrated alar rim and inconspicuous scars. All the reconstructed nasal alae were aesthetically satisfactory. Slight atrophy of grafts was observed in all patients. The shape of the donor ear changed a little. Two patients experienced hyperpigmentation change and one patient presented slight hypertrophic scar in the suture site. No other complications were observed. This simple method not only reconstructed almost normal nasal alar rims and alar grooves but also improved the survival rate of the composite grafts without any free edges. This method also changed the traditional free auricular tissue flap location from the nasal alar rim to the upper alar groove region, which would help achieve more aesthetic appearance. This new method is a creative and useful technique for the repair of full-thickness alar defect.

    Identifying the cause of alar retraction is essential for proper correction of this deformity. In secondary surgery, aimed primarily at cephalic orientation and medialization of the lateral crus, corrections involving spreading and lateralization of the lateral crus can achieve a more horizontal orientation. In their clinic, the authors have practiced the use of an alar spreader graft to support the spread of the lateral crus. For the lateral crus to move freely without any resistance, it is critical to release the nasal hinge and pyriform ligament. A frontal view of the alar notching and the direction of the lateral crus are highly important factors needed to determine the cause of alar retraction. This report describes a new classification system for alar retractions viewed from the front to aid in determining the cause of the retraction and the surgical management. From March 2008 to July 2010, 31 alar retractions were corrected using alar spreader grafts for patients showing clear alar retractions in frontal views. Satisfactory results without severe complications were obtained in 30 cases, with undercorrection in only 1 case. The alar cartilage was completely released to facilitate lateralization and caudal mobilization. An alar spreader graft then was used to support the lateral crus until a biologic scar cast was formed. The use of alar spreader grafts to correct alar retractions provided consistently good results. The attempt also was made to enhance the treatment strategy based on this classification system derived from frontal views of alar retraction.

  12. Anterior septal deviation and contralateral alar collapse.

    2011-01-01

    Septal deviation is often found in conjunction with other pathological conditions that adversely affect nasal patency. Anterior septal deviation, together with contralateral alar collapse, is a relatively rare type of anatomical and functional incompetence. In our experience, it can often be resolved with septoplasty, without the necessity of surgery involving the external valve. The aim of this paper was to verify this hypothesis prospectively. Twelve patients with anterior septal deviation and simultaneous alar collapse on the opposite side were prospectively enrolled in the study. Subjective assessment of nasal patency was made on post-operative day 1, and again 6 months after surgery, using a subjective evaluation of nasal breathing. The width of the nostril (alar-columellar distance) on the side with the alar collapse was measured during inspiration pre-operatively, 1 day after surgery and again 6 months after surgery. Immediately after surgery, all patients reported improved or excellent nasal breathing on the side of the original septal deviation. On the collapsed side, one patient reported no change in condition. With the exception of one patient, all measurements showed some degree of improvement in the extension of the alar-columellar distance. The average benefit 6 months after surgery was an improvement of 4.54 mm. In our group of patients (anterior septal deviation and simultaneous contralateral alar collapse and no obvious structural changes of the alar cartilage) we found septoplasty to be entirely suitable and we recommend it as the treatment of choice in such cases.

    To evaluate the role of creating an alar-based advancement flap in narrowing the nasal base and correcting excessive alar flare. Case series with chart review. This is a retrospective record review study. The study included 35 cases presenting with a wide nasal base and excessive alar flaring. The surgical procedure combined the alar base reduction with alar flare excision by creating a single laterally based alar flap. Any caudal septal deformities and any nasal tip modification procedures were corrected before the nasal base narrowing. The mean follow-up period was 23 months. The mean alar flap narrowing was 6.3 mm, whereas the mean width of sill narrowing was 2.9 mm. This single laterally based advancement alar flap resulted in a more conservative external resection, thus avoiding alar wedge overresection or blunting of the alar-facial crease. No cases of postoperative bleeding, infection, or keloid were encountered, and the external alar wedge excision healed with no apparent scar that was hidden in the depth of the alar-facial crease. The risk of notching of the alar rim at the sill incision is reduced by adopting a 2-layer closure of the vestibular floor. The alar base advancement flap is an effective technique in narrowing both the nasal base and excessive alar flare. It adopts a single skin excision to correct the 2 deformities while commonly feared complications were avoided.

    To prospectively analyze the amount of alar flare, factors contributing to alar flare and efficacy of cinch suture as an adjunctive procedure for alar flare reduction. Thirty adult patients with vertical maxillary excess, who underwent Le Fort 1 impaction, were divided into 2 groups of 15 each. Alar cinch was performed as an adjunct procedure in group 2 patients and results were compared to group 1 which was the control group. Measurements were made on the patients and on 1:1 standardized photographs. Group 2 showed a near pre-operative alar position compared to group 1. The alar flare resulting from every millimeter of impaction was significantly less in group 2 compared to group 1. Alar cinch suture restores the normal alar width by preventing the lateral drift of the naso-labial muscle and thereby reducing the postoperative nasal flare significantly.

    Surgical refinement of the wide nasal tip is challenging. Achieving an attractive, slender, and functional tip complex without destabilizing the lower nasal sidewall or deforming the contracture-prone alar rim is a formidable task. Excisional refinement techniques that rely upon incremental weakening of wide lower lateral cartilages (LLC) often destabilize the tip complex and distort tip contour. Initial destabilization of the LLC is usually further exacerbated by "shrink-wrap" contracture, which often leads to progressive cephalic retraction of the alar margin. The result is a misshapen tip complex accentuated by a conspicuous and highly objectionable nostril deformity that is often very difficult to treat. The "articulated" alar rim graft (AARG) is a modification of the conventional rim graft that improves treatment of secondary alar rim deformities, including postsurgical alar retraction (PSAR). Unlike the conventional alar rim graft, the AARG is sutured to the underlying tip complex to provide direct stationary support to the alar margin, thereby enhancing graft efficacy. When used in conjunction with a well-designed septal extension graft (SEG) to stabilize the central tip complex, lateral crural tensioning (LCT) to tighten the lower nasal sidewalls and minimize soft-tissue laxity, and lysis of scar adhesions to unfurl the retracted and scarred nasal lining, the AARG can eliminate PSAR in a majority of patients. The AARG is also highly effective for prophylaxis against alar retraction and in the treatment of most other contour abnormalities involving the alar margin. Moreover, the AARG requires comparatively little graft material, and complications are rare. We present a retrospective series of 47 consecutive patients treated with the triad of AARG, SEG, and LCT for prophylaxis and/or treatment of alar rim deformities. Outcomes were favorable in nearly all patients, and no complications were observed. We conclude the AARG is a simple and effective method for

    Alar rim deformities such as retraction, notching, collapse, and asymmetry are common problems in rhinoplasty patients. Although alar rim deformities may be improved through rhinoplasty, this area is prone to late changes because of scarring of the soft triangles and a paucity of native structural support. The purpose of this study was to analyze the effect of alar contour grafts on primary rhinoplasty. Fifty consecutive primary rhinoplasty patients with preoperative and postoperative photographs who received alar contour grafts were evaluated for alar aesthetics; 50 consecutive primary rhinoplasty patients without such grafts served as controls. Differences among alar retraction, notching, collapse, and asymmetry from anterior, lateral, and basal views were evaluated. Follow-up ranged from 1 to 4 years and was graded on a four-point scale. The average difference between the two groups' aggregate preoperative scores was 0.21 (p = 0.24). The average preoperative and postoperative scores in the nongraft group were significant for worsening retraction, notching, and collapse but insignificant for asymmetry. The preoperative and postoperative scores for the graft group were insignificant for retraction but improved significantly for notching, collapse, and asymmetry. Postoperatively, the aggregate average of the scores in the nongroup was 0.32 points worse (p Alar contour grafts have a clear and important impact on cosmetic results of primary rhinoplasty. Use of alar contour grafts has been shown to improve aesthetics, whereas there is a worsening of the measured parameters postoperatively without use of these grafts. Therapeutic, III.

  18. Bilateral alar cartilage reduction rhinoplasty allows primary repair of alar defects in the bulbous nose.

    Plastic surgeons have many reconstructive options for lower nasal skin defects, but given the unique aesthetic features of nasal skin the best source for reconstruction is nasal skin itself, when sufficient quantity exists. The purpose of this study is to determine the outcome of bilateral alar cartilage reduction rhinoplasty in combination with a nasal flap to facilitate immediate reconstruction of defects of the nasal tip, soft triangle and alar margin. This prospective study analyzed the aesthetic outcome after reconstruction with bilateral alar cartilage reduction rhinoplasty to reduce the nasal rim and create an excess of skin sufficient to facilitate immediate reconstruction of defects of the nasal tip, soft triangle and alar margin. All wounds healed primarily and patient satisfaction was achieved. Bilateral alar cartilage reduction rhinoplasty allows single-stage reconstruction of defects of the nasal tip, soft triangle, and medial alar rim in the bulbous nose. By placing incisions along the borders of the aesthetic subunits, this novel approach to primary reconstruction of the nasal tip, soft triangle, and medial alar rim provides skin with a superior color and texture match, maintains a satisfactory contour of the nasal rim, and optimizes the likelihood of good scar quality.

    2013-08-01

    Congenital deficiencies of the alar cartilages are rare and often visible at birth but can occasionally present later. The authors review the anatomical development and discuss the incidence and treatment of congenital defects within the alar cartilages seen in rhinoplasty cases. The charts of 869 consecutive patients who underwent open rhinoplasty were retrospectively reviewed, and 8 cases of congenital defects of the alar cartilage within the middle crura were identified. Intraoperative photographs were taken of the alar deformities, and each patient underwent surgical correction. To simplify analysis, a classification of the defects was developed. A division was a cleft in the continuity of the alar cartilage with the 2 ends separate. A gap was a true absence of cartilage ranging from 1 to 4 mm, which can be accurately assessed in unilateral cases. A segmental loss was a defect greater than 4 mm. The 8 cases of deformity could be classified as 4 divisions, 3 gaps, and 1 segmental loss. None of the patients had a history of prior nasal trauma or nasal surgery. Six patients were women and 2 patients were men. In all cases, adequate projection and stability were achieved with a columellar strut. Asymmetry was minimized through concealer or tip grafts. There were no complications. Surgeons performing rhinoplasty surgery will encounter and should be prepared to deal with unexpected congenital defects of the alar cartilage. These defects within the middle crura will require stabilization with a columellar strut and, often, coverage with a concealer tip graft. We speculate that the cause of these defects is a disruption of the hedgehog signals that may arrest the condensation or block the differentiation of the underlying neural crest cells.

    Rhinoplasty surgeons routinely excise or incise the lateral crura despite nostril rim retraction, bossa, and collapse. Given recent emphasis on preserving the lateral crura, a review of the lateral crura's anatomy is warranted. The authors quantify specific anatomical aspects of the lateral crura in cadavers and clinical patients. This was a 2-part investigation, consisting of a prospective clinical measurement study of 40 consecutive rhinoplasty patients (all women) and 20 fresh cadaver dissections (13 males, 1 female). In the clinical phase, the alar cartilages were photographed intraoperatively and alar position (ie, orientation), axis, and width were measured. Cadaver dissections concentrated on parts of the lateral crura (alar cartilages and alar ring) that were inaccessible clinically. Average clinical patient age was 28 years (range, 14-51 years). Average cadaver age was 74 (range, 57-88 years). Clinically, the distance of the lateral crura from the mid-nostril point averaged 5.9 mm, and the cephalic orientation averaged 43.6 degrees. The most frequent configuration of the axis was smooth-straight in the horizontal axis and a cephalic border higher than the caudal border in the vertical axis. Maximal lateral crura width averaged 10.1 mm. In the cadavers, average lateral crural dimensions were 23.4 mm long, 6.4 mm wide at the domal notch, 11.1 mm wide at the so-designated turning point (TP), and 0.5 mm thickness. The accessory cartilage chain was present in all dissections. The lateral crura-alar ring was present in all dissections as a circular ring continuing around toward the anterior nasal spine but not abutting the pyriform. The lateral crura (1) begins at the domal notch and ends at the accessory cartilages, (2) exhibits a distinct TP from the caudal border, (3) has distinct horizontal and vertical vectors, and (4) should have a caudal border higher than the cephalic border. Alar malposition may be associated with position, orientation, or configuration.

    1987-03-01

    Nineteen upper cervical spine specimens were dissected to examine the macroscopic and functional anatomy of alar ligaments. They are on both sides, symmetrically placed, approximately 10-13 mm long and elliptical in cross-section 3 X 6 mm in diameter. The fiber orientation is dependent on the height of dens axis, mostly in the cranial caudal direction. In 12 specimens there was a ligamentous connection between dens and lateral mass of the atlas as a part of the alar ligament. In 2 specimens anterior atlanto-dental ligament was identified. The computerized tomographic (CT) images can clearly show alar ligaments in axial, coronal, and sagittal planes. The ligaments limit the axial rotation in the occipito-atlanto-axial complex (to the right by left alar and vice versa) as well as in side bending. The ligament is most stretched, and consequently most vulnerable, when the head is rotated and in addition flexed. This mechanism, common in whiplash injuries, could lead to irreversible overstretching or rupture of the ligaments especially as the ligaments consist of mainly collagen fibers.

    2007-01-01

    To evaluate the role of the combined alar base excision technique in narrowing the nasal base and correcting excessive alar flare. The study included 60 cases presenting with a wide nasal base and excessive alar flaring. The surgical procedure combined an external alar wedge resection with an internal vestibular floor excision. All cases were followed up for a mean of 32 (range, 12-144) months. Nasal tip modification and correction of any preexisting caudal septal deformities were always completed before the nasal base narrowing. The mean width of the external alar wedge excised was 7.2 (range, 4-11) mm, whereas the mean width of the sill excision was 3.1 (range, 2-7) mm. Completing the internal excision first resulted in a more conservative external resection, thus avoiding any blunting of the alar-facial crease. No cases of postoperative bleeding, infection, or keloid formation were encountered, and the external alar wedge excision healed with an inconspicuous scar that was well hidden in the depth of the alar-facial crease. Finally, the risk of notching of the alar rim, which can occur at the junction of the external and internal excisions, was significantly reduced by adopting a 2-layered closure of the vestibular floor (P = .01). The combined alar base excision resulted in effective narrowing of the nasal base with elimination of excessive alar flare. Commonly feared complications, such as blunting of the alar-facial crease or notching of the alar rim, were avoided by using simple modifications in the technique of excision and closure.

The authors report a new case and review the literature, morbid anatomy, and pathogenesis of this rare injury. The patient in their case, a 9-year-old girl, fell head first from a height of 5 feet off the ground. She presented with neck pain, a leftward head tilt, and severe limitation of right rotation, extension, and right lateral flexion of the neck. Plain radiographs and CT revealed no fracture but a shift of the dens toward the right lateral mass of C-1. Magnetic resonance imaging of the cervical spine showed signal hyperintensity within the left dens-atlas space on both T1- and T2-weighted sequences and interruption of the expected dark signal representing the left alar ligament, suggestive of its rupture. After 12 weeks of immobilization in a Guilford brace, MRI showed lessened dens deviation, and the patient attained full and painless neck motion. Including the patient in this case, the 7 patients with this injury were between 5 and 21 years old, sustained the injury in traffic accidents or falls, presented with marked neck pain, and were treated with external immobilization. All patients had good clinical outcome. The mechanism of injury is hyperflexion with rotation. Isolated unilateral alar ligament rupture is a diagnosis made by excluding associated fracture, dislocation, or disruption of other major ligamentous structures in the craniovertebral junction. CT and MRI are essential in establishing the diagnosis. External immobilization is adequate treatment.

    A boomerang-shaped alar base excision is described to narrow the nasal base and correct the excessive alar flare. The boomerang excision combined the external alar wedge resection with an internal vestibular floor excision. The internal excision was inclined 30 to 45 degrees laterally to form the inner limb of the boomerang. The study included 46 patients presenting with wide nasal base and excessive alar flaring. All cases were followed for a mean period of 18 months (range, 8 to 36 months). The laterally oriented vestibular floor excision allowed for maximum preservation of the natural curvature of the alar rim where it meets the nostril floor and upon its closure resulted in a considerable medialization of alar lobule, which significantly reduced the amount of alar flare and the amount of external alar excision needed. This external alar excision measured, on average, 3.8 mm (range, 2 to 8 mm), which is significantly less than that needed when a standard vertical internal excision was used ( P < 0.0001). Such conservative external excisions eliminated the risk of obliterating the natural alar-facial crease, which did not occur in any of our cases. No cases of postoperative bleeding, infection, or vestibular stenosis were encountered. Keloid or hypertrophic scar formation was not encountered; however, dermabrasion of the scars was needed in three (6.5%) cases to eliminate apparent suture track marks. The boomerang alar base excision proved to be a safe and effective technique for narrowing the nasal base and elimination of the excessive flaring and resulted in a natural, well-proportioned nasal base with no obvious scarring. © Thieme Medical Publishers.

    The alar lobule, alar margin, and soft triangle facet are receiving more attention in the literature as critical elements to address both preoperatively and during rhinoplasty. We have found that the use of the articulated alar rim graft (AARG) corrects deficiencies in these areas as well as provides mechanical stability to the external valve. In this article, we describe indications for AARG, describe in detail the procedure for AARG placement, and highlight the transformation AARGs can achieve in two illustrated case studies.

    Alar vertical discrepancy including alar base has been viewed as one of the most challenging reconstructive problems in rhinoplasty. The authors have created a simple technique that consistently gives aesthetically acceptable results. The authors have designed the seesaw technique to correct alar discrepancy (type 1 to 3). Type 1 has been used in 14 patients, type 2 has been used in three patients, and type 3 has been used in seven patients. Alar discrepancy was corrected satisfactorily in all cases, with good cosmetic outcome. One case required scar revision and another case required revision for overcorrection; satisfactory results were ultimately achieved in both cases. This new technique is quite easy to design and is effective in the correction of alar discrepancy. It yields good postoperative results along with satisfactory aesthetic outcomes.

    The purpose of this systematic review is to evaluate the efficacy of a new modified alar base cinch suture by comparing it with the commonly used classic alar base suture after LeFort I osteotomy. A comprehensive search strategy was performed to include interventional studies involving the comparisons of alar base suturing methods after LeFort I osteotomy. Data analyses were conducted using the random-effects model. Three studies with 146 participants undergoing LeFort I maxillary osteotomy were included in this review. The results showed that, compared with the classic method, both modified transseptal alar base suture and modified reinsertion sutures significantly decreased postoperative alar and alar base widening. The modified alar base cinch suture was more effective than the classic alar base suture in maintaining preoperative alar and alar base width after LeFort I osteotomy. Copyright © 2014 Elsevier Inc.

    Resecting the cephalic component of the lateral crus in an attempt to reduce tip bulbosity has the potential to aggravate and/or cause alar retraction. It is a more serious problem for those patients who exhibit borderline alar retraction. Fourteen primary rhinoplasty patients with borderline alar/columellar relationships for alar retraction formed the study. They did not warrant frank treatment of alar retraction but did exhibit tip bulbosity. An "island" of cephalic lateral crus was developed by an intercartilaginous incision and another 6 mm cephalic to the caudal border of the lateral crus. One or more mattress sutures were placed in the main body of the lateral crus to stiffen and straighten it. The "island" of cephalic crus was then slipped under the main body of the lateral crus. At 11 months to 2(1/2) years, 13 of the 14 patients demonstrated no significant change in their preoperative alar/columellar relationships. Bulbosity was corrected in all patients. One patient, however, required a revision using an alar contour rim graft. The mean preoperative alar-nostril axis measurement was 1.48 mm (range, 1.3 to 1.9 mm) in contrast to a mean postoperative measurement of 1.71 mm (range, 1.5 to 2.2 mm). A one-tailed paired t test indicated no statistically significant difference between preoperative and postoperative values. The cephalic part of the lateral crus can act as a lateral crural strut to maintain the ala in a more caudal position. The technique is useful for borderline alar retraction and when lengthening the short nose for which there is a need to preserve side wall length.

    2017-09-01

    Distraction osteogenesis with a rigid external distractor is a widely accepted treatment for midfacial hypoplasia. In this study, the authors introduce the utilization of alar pinning with the external halo distractor for maxillary advancement, in place of an oral splint. A retrospective chart review was conducted of 7 patients who successfully underwent distraction osteogenesis using the alar pinning technique. Midfacial hypoplasia was secondary to Crouzon syndrome (n = 4), Apert syndrome (n = 1), Pfeiffer syndrome (n = 1), or bacterial meningitis (n = 1). Three patients were managed with monobloc osteotomies, 2 with Le Fort III osteotomies, 1 with Le Fort III osteotomy and frontoorbital advancement, and 1 with Le Fort I osteotomy alone. Patient charts were analyzed for postoperative course and complications relating to the alar pins. Two patients had minor complications specifically related to the alar pins. One patient had concern for a mild skin infection at a pin site that resolved with oral antibiotics. The other patient had loosening of an alar pin, which did not require operative management. Retrospective chart review indicated that all patients were pleased with their results from the distraction, and no patients opted for further advancement. Utilization of alar pin sites for external distraction is a feasible and reasonable option for treatment of midfacial hypoplasia involving a Le Fort osteotomy or monobloc procedure. Fixation sites within the alar crease minimize the visibility of pin site scars and eliminate the need for a custom-made oral splint, which prevents usage of the upper dentition and frequently requires consulting a dentist or orthodontist for fabrication. Alar pinning with an external halo distraction system for management of midfacial hypoplasia has minimal complications and is an alternative to using a custom-made oral splint.

    The morphology of the alar ligaments has been inconsistently described, particularly with regard to the existence of an atlantal portion. Despite these inconsistencies, these descriptions have been used to develop physical tests for the integrity of these ligaments in patients with cervical spine problems. The purpose of this study was to describe the detailed macrostructure of the alar ligaments. The alar ligaments of 11 cervical spine specimens from embalmed adult cadavers were examined by fine dissection. A detailed description of the macrostructure of these ligaments and their attachment sites was recorded. Measurements were performed with respect to ligament dimensions and relations with selected bony landmarks. No atlantal portion of the alar ligament was viewed in any specimen. The attachment of the ligaments on the odontoid process occurred on its lateral and posterolateral aspects, frequently below the level of the apex. The occipital attachment was on the medial surface of the occipital condyles in close proximity to the atlanto-occipital joints. The orientation of the ligaments was primarily horizontal. The presence of transverse bands extending occiput to occiput with minimal or no attachment to the odontoid process was a common variant. The absence of findings with respect to the atlantal portion of the alar ligament suggests that it may be considered an anatomical variant, not an essential component for stability of the craniocervical complex. These findings may inform the use and interpretation of clinical tests for alar ligament integrity.

    The nasal ala is an attractive site for pulse oximetry because of perfusion by branches of the external and internal carotid arteries. We evaluated the accuracy of a novel pulse oximetry sensor custom designed for the nasal ala. After IRB approval, healthy non-smoking subjects [n=12; aged 28 (23-41) yr; 6M/6F] breathed hypoxic mixtures of fresh gas by a facemask to achieve oxyhaemoglobin saturations of 70-100% measured by traditional co-oximetry from radial artery samples. Concurrent alar and finger pulse oximetry values were measured using probes designed for these sites. Data were analysed using the Bland-Altman method for multiple observations per subject. Bias, precision, and accuracy root mean square error (ARMS) over a range of 70-100% were significantly better for the alar probe compared with a standard finger probe. The mean bias for the alar and finger probes was 0.73% and 1.90% (Palar and finger probes, respectively. The within/between-subject variation for the alar and finger probes were 1.14/1.57% and 1.87/1.47%, respectively. The limits of agreement were 3.96/-2.50% and 5.48/-1.68% for the alar and finger probes, respectively. Nasal alar pulse oximetry is feasible and demonstrates accurate pulse oximetry values over a range of 70-100%. The alar probe demonstrated greater accuracy compared with a conventional finger pulse oximeter. © The Author [2014].

    2001-11-01

    To describe an alar cartilage-modifying technique aimed at decreasing nasal tip projection in cases with overdeveloped alar cartilages and to compare it with other deprojection techniques used to correct such deformity. Selected case series. University and private practice settings in Alexandria, Egypt. Twenty patients presenting for rhinoplasty who had overprojected nasal tips primarily due to overdeveloped alar cartilages. All cases were primary cases except for one patient, who had undergone 2 previous rhinoplasties. An external rhinoplasty approach was used to set back the alar cartilages by shortening their medial and lateral crura. The choice of performing a high or low setback depended on the preexisting lobule-to-columella ratio. Following the setback, the alar cartilages were reconstructed in a fashion that increased the strength and stability of the tip complex. Subjective evaluation included clinical examination, analysis of preoperative and postoperative photographs, and patient satisfaction. Objective evaluation of nasal tip projection, using the Goode ratio and the nasofacial angle, was performed preoperatively and repeated at least 6 months postoperatively. A low setback was performed in 16 cases (80%) and a high setback in 4 (20%). The mean follow-up period was 18 months (range, 6-36 months). The technique effectively deprojected the nasal tip as evidenced by the considerable postoperative decrease in values of the Goode ratio and the nasofacial angle. No complications were encountered and no revision surgical procedures were required. The alar setback technique has many advantages; it results in precise predictable amounts of deprojection, controls the degree of tip rotation, preserves the natural contour of the nasal tip, respects the tip support mechanisms, increases the strength and stability of nasal tip complex, preserves or restores the normal lobule-to-columella proportion, and does not lead to alar flaring. However, the technique requires

    Autopsy findings of ligaments of the upper cervical spine were compared with magnetic resonance imaging (MRI) findings. Ligaments were clearly shown as hypointensity on T1-weighted images and proton density images. Transverse images were useful in diagnosing alar and transverse atlantal ligament injuries. When there is a bilateral difference in the alar ligaments, ruptured ligament is suspected. Transverse ligament rupture was shown on interrupted hypointensity and as hyperintensity. MRI was capable of diagnosing alar ligament rupture in 8 of 11 patients, and transverse ligament rupture in all 3 patients. In 2 patients having Jefferson's fracture and injuried atlanoaxial subluxation encountered in the clinical practice, transverse ligament rupture was similarly observed as that in autopsy cases on MR images. Hyperintensity in the transverse ligament rupture area was seen even one year after injury. Injured transverse ligament was seen as swollen hyperintensity on sagittal images; and the hyperintensity was gradually decreased with the process of healing. (N.K.).

    Combined sill and alar excision is a useful procedure for correcting a wide nasal base and flared alar lobules. However, the aesthetic outcomes of this technique remain poorly reported. To evaluate the aesthetic outcomes of combined sill and alar excision in Asian patients undergoing rhinoplasty. A retrospective cohort study of 73 consecutive patients who underwent combined sill and alar excision from March 1, 2004, to January 31, 2013, was conducted at a tertiary referral hospital in Korea. Combined sill and alar excision. Changes in the ratio of the interalar distance to intercanthal distance and frequencies of alar flaring, nostril symmetry, and nostril shape, as measured by reviewing photographs taken before and after the surgery. Among the 73 patients (50 men and 23 women; mean [SD] age, 36.5 [12.3] years) the mean (SD) ratio of interalar distance to intercanthal distance changed significantly from 1.07 (0.11) to 1.04 (0.08) (P alar flaring, 45 (75%) no longer had flaring after the procedure. The frequency of nostril symmetry increased from 38 patients (52%) to 46 (63%) (P alar deformity (1 patient [1%]), unsatisfactory correction of asymmetrical nostrils (1 [1%]), and unsatisfactory correction of alar flaring (2 [3%]). Combined sill and alar excision was a useful technique with a low complication rate for correcting wide alar base, alar flaring, nostril asymmetry, and nostril shape. 4.

    Among the various types of alar deformations in Asians, alar retraction not only has the highest occurrence rate, but is also very complicated to treat because the ala is supported only by cartilage and its soft tissue envelope cannot be easily stretched. As patients' knowledge of aesthetic procedures is becoming more extensive due to increased information dissemination through various media, doctors must give more accurate, logical explanations of the procedures to be performed and their anticipated results, with an emphasis on relevant anatomical features, accurate diagnoses, detailed classifications, and various appropriate methods of surgery.

    This study assesses the efficacy of alar suspension sutures in the management of nasal valve collapse causing nasal obstruction. These sutures are inserted between the vestibular skin and lateral crura and hitched to the periosteum of the medial inferior orbital margin; this is a variation of the alar (change everywhere) suspension suture technique. A retrospective review of patients who underwent alar suspension suture insertion between January 2009 and December 2010 in the management of nasal obstruction was undertaken. Symptoms of nasal obstruction were assessed using the Visual Analogue Scale (VAS) and peak inspiratory flow rate (PIFR). This was measured preprocedure and repeated at 3, 6, and 12 months postoperatively. A total of 35 patients were identified, and 26 were included in the study; 90% of patients were satisfied with the outcome of surgery, supported by improvement in the VAS and PIFR scores. The mean difference in VAS preprocedure and postprocedure was 4.97 (P value = 0.00), and the average improvement in PIFR was 25.5 L/min (P value = 0.00). Our study shows a significant improvement in patient's symptoms following insertion of alar suspension sutures. It is, therefore, a reliable, safe, and effective technique in treating nasal obstruction secondary to nasal valve collapse. © The Author(s) 2015.

    2014-12-01

    Alar rim contour and alar rim grafts have become essential components of rhinoplasty. Ideally, grafts of the nose should be anatomical in shape. So doing might make grafts of the alar rim more robust. The authors considered doing that by applying the graft as a continuous extension of the lateral crus. Twelve patients (two men and 10 women) constituted the study group (seven primary and five secondary cases). Of those, there were five concave rims, two concave rims with rim retraction, two boxy tips, and three cephalically oriented lateral crura. Surgical technique included the following: (1) an open approach was used; (2) a marginal incision that ignored the caudal margin of the lateral crus (the incision went straight posteriorly to a point 5 to 6 mm from the rim margin) was used; (3) a triangular graft was made to cover the exposed vestibular skin; (4) it was secured end to end to the caudal border of the lateral crus; and (5) the poster end was allowed to sit in a small subcutaneous pocket. Follow-up was 11 to 19 months. All 12 patients exhibited good rims as judged by a blinded panel. Rim retraction was not fully corrected in one patient, but no further treatment was required. One patient did require a secondary small rim graft for residual rim concavity. The concept of grafting the alar rim is strongly supported by the authors' results. The modifications the authors applied by designing the graft to be anatomical in shape has been a technical help.

    Various authors have described the morphology of the alar ligaments; however, there are no reports of a cadaveric study focusing on their attachments onto the dens. The purpose of this study was to use fresh cadaveric specimens to describe in detail different attachment patterns of the alar ligaments onto the dens. This study used 22 sides from 11 fresh frozen cadaveric heads. Specimens were obtained from 8 men and 3 women who were 67-99 years old at death. Dissection of the exact attachment of the alar ligaments onto the dens was observed from posterior, superior, and anterior views under the surgical microscope. From a posterior view, 6 alar ligaments passed over the tip of the dens, and 16 alar ligaments attached onto the posterolateral part of the dens; the right and left ligaments had no continuity. From a superior view, the alar ligament was classified in 2 ways: depending on the covered area of the dens (entirely or posterior two thirds) and continuity of the alar ligament (transversely, separately, or combination). Fourteen alar ligaments covered the posterior two thirds of the dens. From an anterior view, in 1 specimen, the alar ligament extended to the anterior surface of the dens. Wide posterolateral anchoring to the dens coupled with the nearly horizontal trajectory explains the biomechanical advantage of the alar ligaments in undertaking a stabilizing function in limiting head rotation that would otherwise be ineffective in the case of weaker attachments or a more vertical orientation.

    To present the aesthetic and functional outcomes of nasal alar reconstruction in Asian patients and to propose a working surgical algorithm. Seventeen patients underwent nasal alar reconstruction at a university-based facial plastic surgery practice from March 1, 1998, through February 28, 2010. The male-female ratio was 10:7, with a median age of 59 years (range, 34-78 years), and the mean follow-up duration was 64 months. The defect was mostly caused by basal cell carcinoma resection (14 of 17 [82%]), followed by the resection of squamous cell carcinoma, trauma, and excision of a previous scar. The mean defect size was 1.71 cm (range, 1-4 cm). The full-thickness defects were noted for 8 patients, whereas 9 had partial-thickness defects. The choice of reconstruction method was primarily based on the size and depth of the surgical defect. Most of the defects 1 to 2 cm in diameter needed nasolabial flaps (10 of 17 [59%]), whereas full-thickness defects larger than 2 cm needed forehead flaps (3 of 17 [18%]) to reconstruct the external defect. Smaller defects less than 1 cm were reconstructed with composite grafts (2 of 17 [12%]), a bilobed flap (1 of 17 [6%]), or primary closure (1 of 17 [6%]). Seven of 8 full-thickness defects had the internal nasal lining reconstructed using a septal mucoperichondrial flap, and 1 case was reconstructed using a cutaneous turn-in flap. Reinforcement cartilage graft was used in 8 patients. No flap failure occurred except in 1 case, in which necrosis of the internal lining flap caused contraction of the external flap with resultant alar rim elevation. An elevation of the alar margin and alar groove blunting occurred in 3 cases. No functional problems emerged. Subjective surgical outcome on a 4-point satisfaction scale revealed that 5 patients (29%) were much satisfied, 10 patients (59%) were satisfied, 1 patient (6%) was fairly satisfied, and 1 patient (6%) was dissatisfied. The choice of reconstruction method of nasal alar defect in

    Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. Standard photographs are performed in the face and lateral views with forward gaze in the repose and maximum smile. Nasal length, alar base, and alar flaring were measured on the prints of the photographs. To decrease possible errors in the size of the printed photographs, middle face height from glabella to ANS was measured in the lateral view and the interpupil distance in the face view to standardize the measurements. Fifty cases were enrolled in this study. In 39 cases (78%), the nasal length was increased during smile. Forty-six cases (92%) had an increase in alar base diameter during smile. Alar flaring during smile increased in 48 cases (96%). Nasal length and alar base changes during smiling were not significantly correlated. Nasal length and alar flaring changes during smiling were not significantly related too. On the other hand, alar base and alar flaring changes during smile showed correlation. Alar base and alar flaring changes during smile were not significantly different in hyperactive and non-hyperactive cases. Nasal length change during smiling and hypertrophy of the medial fascicles of depressor septi nasi were not related to alar base or alar flaring change during smile.

    In this article, we will examine a case of cutaneous angiomyolipoma in the right nasal alar base area of a 36-year-old man. Generally, angiomyolipoma occurs in the kidney and, histologically, has features that are similar to cutaneous angiomyolipoma: smooth muscle cells, mature adipose cells, and a convoluted thick-walled blood vessel. Clinically, renal angiomyolipoma is related to tuberous sclerosis, but cutaneous angiomyolipomas occur very rarely, with a total of only 23 cases documented in the literature, with 39% (9/23) of those cases occurring in the ear or surrounding areas. In particular, the abundance of blood vessels inside a cutaneous angiomyolipoma produces good enhancement on computed tomographic image, making it easy for the tumor to be mistaken for a vascular tumor. In this particular case, we will report about a previously unheard case of cutaneous angiomyolipoma occurring in the nasal alar base that was mistaken for a vascular tumor.

    Cervical spine trauma most commonly involves the lower parts in adults. In children lesions of the cervical spine can predominantly be found in the region of C1/C2 including ligament injuries at this level. However such injuries are difficult to detect and only few data are available concerning therapy and prognosis of atlantoxial ligament lesions. We report on two children suffering from isolated rupture of the alar ligaments. Both injuries were proven by magnetic resonance imaging which is recommended as the resource of choice for the evaluation of the cervical spine soft tissues in children. Although the biomechanic properties of the alar ligaments remain unclear non-operative treatment for the rupture of these ligaments seems to be adequate. In order to avoid neurologic symptoms or long term complications an immediate diagnosis is indispensable.

    Ligament disruptions at the craniovertebral junction are typically associated with atlantoaxial rotatory dislocation during upper cervical spine injuries and require external orthoses or surgical stabilization. Only in few patients isolated ruptures of the alar ligament have been reported. Here we present a further case, in which the diagnosis was initially obscured by a misleading clinical symptomatology but finally established six month following the trauma, demonstrating the value of contrast-enhanced high resolution 3 Tesla magnetic resonance imaging in identifying this particular lesion.

    An observational study of variations in the appearance of the alar ligament on magnetic resonance imaging (MRI) and the normal range of lateral flexion and rotation of the atlas was performed to validate some of the premises underlying the use of MRI for the detection of injuries to the alar ligament. Fifteen healthy volunteers were included. Three sets of coronal proton-density images, and axial T2-weighted images of the craniovertebral junction, were obtained at 0.5 T with the neck in neutral position and laterally flexed (coronal proton density) or rotated (axial T2). Five of the subjects also underwent imaging at 1.5 T. The scans were independently examined twice by two radiologists. The presence of alar ligaments was recorded and a three-point scale used to grade the extent of hyperintensity exhibited by the structures: the ligament were graded as 2 and 3 if, respectively, less or more of its cross-section was hyperintense, whereas grade 1 represented a hypointense ligament. The effect of lateral flexion on image quality was assessed. Concordance analysis of the data were performed before and after dichotomising the data on grading. The atlanto-axial angle and rotation of the atlas were measured. The magnitude of movement to right was normalised to that to the left to give, respectively, the flexion index and the rotation index. The alar ligaments were most reliably seen on coronal proton-density scans, with a Maxwell's RE of 0.96 as compared with 0.46 for sagittal images. Flexion of the neck improved definition of the ligaments in only rare instances. (orig.)

    2012-09-01

    The correction of alar webbing in unilateral cleft lip nose deformity is challenging because of progressive distortions in the alar web region during the period of growth. Alar webbing is a persistent universal deformity in both the primary and secondary cleft lip noses. The purpose of this article is to study the alar web deformity in adult patients with unilateral cleft lip noses. Twenty-five patients aged 13 years and older presenting with unilateral cleft nasal deformity were included. Preoperative and postoperative measurements of the nose, along with detailed intraoperative recording of the deformed anatomy, were done. Preoperative magnetic resonance imaging was also done in selected cases. Transcolumellar open rhinoplasty was performed in all the cases, and nasal septal straightening with centralization was done. Cleft alar base augmentation was done using bone graft to restore symmetry of the nasal tripod. Both the cleft and noncleft alar cartilages were extensively mobilized from the skin and mucosal sides. The overgrown and caudally slumped cleft-side alar cartilage was resected caudally and was then resuspended in a symmetrical position with the noncleft alar cartilage. A midline-strut septal cartilage extension graft was used to restore the tip aesthetics. The skin overlying the alar web was in-rolled after semilunar cartilage resection, and skin excision was also done to restore symmetry with the opposite vestibule. The remaining secondary cleft nasal and lip deformities were corrected depending upon the specific presenting pathologic abnormality. The cleft alar cartilage was found to be caudally displaced in all the cases. The caudal border of the lateral crus was prolapsing in the cavity of the vestibule on the superomedial aspect and was tenting the skin in the area of the weak triangle, producing the characteristic alar web deformity. In the study group, the maximum width of the cleft alar cartilage at the level of the lateral crus was increased by

    Alar cartilage malposition is a common anatomic variation in which the axis of the lateral crus lies cephalically and may be parallel to the cephalic septum. Malposition of the lateral crura may produce inward collapse of the alae that is observable on deep inspiration. The authors performed the alar rim flap technique to treat patients with alar malposition and assessed functional and aesthetic outcomes. Twelve patients who underwent primary open rhinoplasty with the alar rim flap technique were evaluated in a prospective study. A 2- or 3-mm caudal portion of the lateral crus was elevated from the underlying mucosa, pulled caudally, and extended with a cartilage graft. This extension of the alar rim flap was placed through the pyriform aperture for additional support. Patients completed pre- and postoperative questionnaires addressing nasal obstruction and underwent paranasal computed tomography. Patients received follow-up for an average of 16 months (range, 8-27 months). Patients with alar cartilage malposition and external valve insufficiency experienced aesthetic and functional improvements after rhinoplasty with the alar rim flap technique. No patients developed alar rim collapse or flap displacement. The alar rim flap technique is effective for the correction of malpositioned lateral crura and external valve insufficiency. Because this technique does not damage the scroll area, disruption of the internal valve area is avoided. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    2015-12-01

    To determine whether identification and incorporation of the pyriform ligament in the alar cinch results in decreased alar base widening compared with standard alar cinch techniques. This was a retrospective case series and the sample was composed of patients undergoing Le Fort I osteotomy. Intraoperatively, the pyriform ligament was identified and incorporated in the alar cinch suture. Greatest alar width (GAW) measured immediately after closure was compared with GAW measured at least 5 months postoperatively. The change in alar base width was compared with that reported in the literature using other alar cinch techniques. Two case examples are reported. The sample was composed of 15 patients (mean age, 27.1 yr; 27% female). The mean postoperative change in GAW was 1.0 ± 0.6 mm (2.59 ± 1.59%). Postoperative change in alar base width reported in the literature ranged from 0.5 to 10.8%. The pyriform ligament is easily identified during exposure of the maxilla and pyriform aperture and can be used to control widening of the alar base after Le Fort I osteotomy.

    The objective of this study was to show the use and effectiveness of nasal alar rim flap on the correction of unilateral cleft lip nasal deformity. Thirty-one patients (age range, 10-29 years; mean, 15.1 years; 14 male and 17 female patients) with unilateral cleft lip underwent rhinoplasty surgery using alar rim flap. The excessive skin of nasal alar was marked, then a skin flap was raised. This flap can be transferred medially (type 1) or laterally (type 2) to narrow the nostril or to augment the nasal sill and, of course, to correct the alar web deformity. Preoperative and postoperative photographs were measured for photogrammetric analysis in 16 patients. The alar rim flap used in patients with unilateral cleft lip made the nostrils more symmetrical. The nostril sill was augmented with flap type 1. The alar base width was narrowed with flap type 2 (P = 0.03). The alar web deformity was corrected. The alar rim flap could be an ideal treatment option for correction of alar web deformity in patients of unilateral cleft lip.

    There are many scaffold materials of repairing nasal alar cartilage defects. Auricuiar cartilage was used extensively in terms of its abundant tissues, good elasticity, little donor-site malformation, good plasticity etc. The authors dissected auricular cartilage and nasal alar cartilage, measured cartilage's morphous data and found some similar territories with nasal alar cartilage in the structure of auricular cartilage. An anatomical study was performed using 10 adult cadavers acquired through Plastic Surgery Hospital, Peking Union Medical College, Beijing, China. Seven male and three female cadav-ers were included in the study. Harvest 20 auricular cartilage specimens and 20 nasal alar cartilage specimens. Then, Computed Tomography Scan on the auricular cartilage and nasal alar cartilage were performed. The datas were imported into mimics and three-dimensional reconstructions of the auricular cartilage and nasal alar cartilage were carried on. Parts of the auricular cartilage, such as conchal fossa, tragus, intertragic notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are ana-tomically similar to nasal alar cartilage. This study reports the anatomy of auricular cartilage and nasal alar cartilage, found some territories in the auricular cartilage, such as conchal fossa, tragus, intertragic notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are anatomically similar to nasal alar cartilage. This research provides the anatomical basis that auricular cartilage was used to repair the nasal cartilage defect.

    Post-traumatic changes of the alar ligaments have been proposed to be the cause of chronic pain in patients after whiplash injury of the cervical spine. In addition to an asymmetric dens position, widening of the atlantodental distance to more than 12 mm can be an indirect sign of an alar ligament rupture. CT is recommended for detection of a avulsion fracture of the occipital condyle. Isolated ruptures of the alar ligaments are best visualized on MRI. In patients with chronic impairments after whiplash injuries changes of the alar ligaments on MRI must be differentiated from normal variants in healthy individuals.

    The purpose of this study is to observe the affection of different clinical surgeries on alar nasal cartilages' growth and development. The experimental results can provide some theory basis for clinical surgeries. Twenty-eight New Zealand immature rabbits were used in this study, and divided into normal control group, hidden dissection group and cutting off alar nasal cartilages group randomly, which included 4,12 and 12 rabbits, separately. Arc incision were made on the mucous membrane of nasal cavity,and then dissect the alar nasal cartilages hidden or cut off the alar nasal cartilages, separately. The growth and development of the alar cartilage were observed at different stages after the surgery using histological and immuno-histochemical methods. Four weeks, eight weeks, twelve weeks and sixteen weeks after surgery, there were no significant differences in the indexes of chondrocytes between hidden dissection group and control group. In cutting off alar nasal cartilages group, fiber tissue were observed in the vacancy left after being cut off cartilages, and even mucous membrane tissue could be seen in some slices. There is no adverse influence on the growth and development of the alar cartilage after being hidden dissected. Contrarily, the restoring capability of transparent cartilage cannot counteract the injury resulted form the surgery after the alar nasal cartilages being cut off.

    This study aims to delineate the morphology, integrity, and distribution of the alar fascia using dissection and E12 sheet plastination. This is the first study that employs E12 sheet plastination to investigate the alar fascia and its adjacent potential spaces. Twenty-nine manual dissections and 3 sets of E12 sheet plastinations were used to examine the posterior pharyngeal region for the architecture and distribution of the alar fascia. Specimens were examined from the inferior nuchal line to C6. The alar fascia originated as a well-defined midline structure at the level of C1 and could be identified down to C6. There was no evidence of the alar fascia between the inferior nuchal line and the base of the skull. Notably, the alar fascia permitted resistance to manual traction. E12 sheet plastination allowed for visualization of the alar fascia's superior attachments within the deep cervical region. Resistance to traction suggests that the alar fascia may be more than just a loose fibroareolar matrix. The findings in this study suggest an alternative point of entry into the danger space. Understanding the continuity of this fascial layer is critically important with regard to the pathophysiology of deep neck space infections. © The Author(s) 2015.

    The alar ligaments are one of the primary ligamentous structures contributing to craniovertebral stability. The purpose of this study is to clarify the morphology of the alar ligament using fresh cadaveric specimens. Twenty-two fresh frozen cadaveric alar ligaments were used in this study. The occiput, C1 and C2 were removed en bloc from each specimen and various measurements and observations, including variations, were documented. The angle formed by both alar ligaments was measured in a neutral position (149±24.19°), as well as during forced flexion (134.18±27.08°) and extension (163.81±24.54°). The current cadaveric evaluation offers an interesting window into better understanding the anatomy of the alar ligaments. Copyright © 2017 Elsevier Inc. All rights reserved.

Some authors accuse posttraumatic changes of alar ligaments to be causative for consequential disturbances. Review of recent studies on biomechanics, anatomical and clinical MR imaging. Biomechanical experiments can not induce according injuries of alar ligaments. Although MRI provides excellent visualization of alar ligaments, the range of normal variants is high. Biomechanical studies give no evidence of alar ligament involvement in whiplash disease. Using MRI, signal alterations of alar ligaments can hardly be differentiated from common normal variants. Functional MRI provides no diagnostic yield.

    Orthognathic surgery has an influence on the overlying soft tissues of the translated bony maxillomandibular complex. Improvements in both function and facial appearance are the goals of surgery. However, unwanted changes to the soft tissues, especially in the nose region, frequently occur. The most common secondary change in the nasolabial region is widening of the alar base. Various surgical techniques have been developed to minimize this effect. The purpose of this study was to evaluate the changes in the nasal region due to orthognathic surgery, especially the alar width and nasal volume, using combined cone beam computed tomography (CBCT) and three-dimensional (3D) stereophotogrammetry datasets. Twenty-six patients who underwent a Le Fort I advancement osteotomy between 2006 and 2013 were included. From 2006 to 2010, no alar base cinch sutures were performed. From 2010 onwards, alar base cinch sutures were used. Preoperative and postoperative documentation consisted of 3D stereophotogrammetry and CBCT scans. 3D measurements were performed on the combined datasets, and the alar base width and nose volume were analyzed. No difference in alar base width or nose volume was observed between patients who had undergone an alar cinch and those who had not. Postoperatively the nose widened and the volume increased in both groups. Copyright © 2016 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

    The aim of this study was to see the histological nature of the alar web and to introduce a featheredged rolled-in flap to reduce the alar web.On a cadaver, the perpendicular section of the alar web revealed a thickened dermis portion on both the skin side and the nasal side distal to the alar cartilage. According to histological results, we thought the thinning and rolling in of the distal margin of the end of the open rhinoplasty incision could reduce the alar web. An open rhinoplasty incision was made just distal to the hair-bearing vestibular skin and a V-Y shape incision created at the alar base. After the cartilage work, the skin of the distal end of the flap was featheredged to a 0.5-mm thickness. The distal margin was rolled in and sutured to the nasal lining. A bolster dressing was applied using a 4-0 nylon suture.Thirteen patients (8 males, 5 females) were operated on, and 8 patients were followed up for more than 12 months. Their preoperative and postoperative worm's eye views were compared. Four anthropometric distances were measured preoperatively and postoperatively. The columellar length increased significantly after the operation (P = 0.001 [independent 2-sample t test]) on the cleft side. Preoperatively, the alar width was significantly greater (P = 0.02 [paired-samples t test]) on the cleft side (0.17 ± 0.03 of an intercanthal distance) than the noncleft side (0.14 ± 0.03). After the operations, they became similar (0.16 ± 0.03 on cleft side, 0.16 ± 0.04 on the noncleft side; P = 1.00 [paired-samples t test]).We think this featheredged rolling-in flap might be a good method for the correction of an alar web since this technique increased the columellar length and decreased the alar width on the cleft side.

    Congenital anatomic deformities or acquired weakness of the lateral crura of the lower lateral cartilages after rhinoplasty could cause alar rim deformities. As lower lateral cartilages are the structural cornerstone of the ala and tip support, deformities and weakness of the alar cartilages might lead to both functional and esthetic problems. In this article, we are introducing sliding alar cartilage flap as a new technique to reshape and support nasal tip. One hundred sixty consecutive patients between 18 and 55 years of age (mean age: 27.51) were included in the study between January 2007 and May 2008. Of the total number of patients 60 were male and 100 of them were female. None of the patients had rhinoplasty procedure including lower lateral cartilage excision previously. Sliding alar cartilage technique was used in an open rhinoplasty approach to shape the nasal tip in all patients. This technique necessitates about 2 to 3 minutes for suturing and undermining the alar cartilages. The follow-up period was between 4 and 18 months. In no patients any revision related to the sliding alar cartilage technique was required. Revision was applied in 3 patients due to thick nasal tip skin and in one patient due to unpleasant columellar scar. In this article, we are presenting the "sliding alar cartilage flap" as a new technique for creating natural looking nasal tip. This technique shapes and supports nasal tip by spontaneous sliding of the cephalic portion of the lower lateral cartilage beneath the caudal alar cartilage, with minimal manipulation, without any cartilage resection, or cartilage grafting.

    While allowing the greatest range of axial rotation of the entire spine with 40° to each side, gradual restraint at the extremes of motion by the alar ligaments is of vital importance. In order for the ligaments to facilitate a gradual transition from the neutral to the elastic zone, a complex interaction of axial rotation and vertical translation via the biconvex articular surfaces is essential. The aim of this investigation is to establish a geometrical model of the intricate interaction of the alar ligaments and vertical translatory motion of C1/C2 in axial rotation. Bilateral alar ligaments including the odontoid process and condylar bony entheses were removed from six adult cadavers aged 65-89 years within 48 h of death. All specimens were judged to be free of abnormalities with the exception of non-specific degenerative changes. Dimensions of the odontoid process and alar ligaments were measured. Graphical multiplanar reconstruction of atlanto-axial rotation was done in the transverse and frontal planes for the neutral position and for rotation to 40° with vertical translation of 3 mm. The necessary fibre elongation of the alar ligaments in the setting with and without vertical translation of the atlas was calculated. The mean diameter of the odontoid process in the sagittal plane was 10.6 mm (SD 1.1). The longest fibre length was measured from the posterior border of the odontoid enthesis to the posterior border of the condylar enthesis with an average of 13.2 mm (SD 2.5) and the shortest between the lateral (anterior) border odontoid enthesis and the anterior condylar enthesis with an average of 8.2 mm (SD 2.2). In graphical multiplanar reconstruction of atlanto-axial rotation to 40° without vertical translation of C1/C2, theoretical alar fibre elongation reaches 27.1% for the longest fibres, which is incompatible with the collagenous structure of the alar ligaments.

    To describe various techniques, including alar base reduction, alar flaring reduction, and alar hooding reduction and present a decision-making treatment algorithm and quantifiable guidelines for soft-tissue excision, along with scar outcomes from a single-surgeon practice. The soft tissue of the nasal tip, ala, and nostrils is important in overall nasal tip dynamics. Excisional alar contouring is an essential part of many successful cosmetic rhinoplasty outcomes. The various soft-tissue excision techniques are described in detail and an algorithm is provided. Quantitative analysis of excision parameters was performed using statistical analysis. Finally, qualitative scar analysis was performed and scar outcomes were statistically derived. Seventy-four patients were female and 26 were male. Of the procedures reviewed, 47% involved alar soft-tissue excision. Alar base reduction was performed in 46 patients (46%). Alar flare reduction was performed in 16 patients (16%). Alar hooding reduction was performed in 2 patients (2%). Mean scar outcome scores ranged from 0.55 to 0.69. Alar soft-tissue techniques are often necessary to achieve a balanced outcome and superior results when performing rhinoplasty surgery. Therefore, they should be an integral part of every rhinoplasty evaluation and surgical plan as indicated.

    The aim of this prospective study was to analyze the efficacy of a new alar base cinch suture by comparing it with the commonly used cinch suture described by Schendel and Delaire in Dr. William Bell's book. Thirty-five patients submitted to maxillary impaction and/or advancements of ≥ 3 mm were randomly divided into 2 groups. Group 1 received an extra oral alar base cinch suture, and patients from group 2 received the classic intraoral suture. Alar and alar base width were measured before and after surgery in digital photographs, with the patient's head in a submental oblique view. Data were reported as means and standard deviations, and difference between groups were determined using Welch t test. A P value of alar base widening was 1.38 mm in group 1 and 2.5 mm in group 2, and mean alar widening was 1.40 mm in group 1 and 2.31 mm in group 2. The difference was statistically significant (P alar base cinch suture was more effective in maintaining preoperative Alar and alar base width compared with classic intraoral nasal suture.

    Soft tissue changes secondary to Maxillary orthognathic surgery are many fold. The alar flare is one among them, which affects the appearance of the patient. Cinch suture has been used to prevent alar flare; but the presence of anaesthetic tube hinders cinching. So, the study was aimed to assess an efficacy of modified nasal to oral tube switch technique for modified alar cinching to prevent alar flare after orthognathic and nasal corrective surgeries. Patients were randomly allocated in each group, who underwent modified alar base cinching with and without nasal to oral tube switch. Changes in alar base width, upper lip length was measured with Digital Vernier Caliper and nasolabial angle (Cotg-Sn-Ls) on lateral cephalogram at 1st, 3rd, 6th, and 12th months after surgery. The time taken and ease of tube switch were noted. The data obtained were tabulated and interpreted using a test of significance. Study results showed no statistical significant difference in perinasal soft changes among both groups. But tube switch appears to be beneficial to prevent alar flare. Modified alar base cinching was performed effectively in patients with a modified tube switch technique. It increased positive results in comparison with non-shift. The technique of tube switch used is effective in prevention of alar flare. Because of small sample size and limited period of follow up, our study suggests multi centre, randomized studies to know the technical difficulties of tube switch for cinching and aesthetic results with varying anaesthetist and the surgeon's experience.

    In many cases, Asians' noses are shorter; their nasal tips have a bulbous shape and typically lack the projection. To correct these problems, we completely dissected the alar cartilage in a three-dimensional manner by which the alar cartilage could be repositioned. Thus, no external force was exerted to the alar cartilage. For approximately 4 years, a total of 502 patients were treated with this surgical method. Using the open rhinoplasty, the alar cartilage was dissected in such a manner that it should be completely isolated from the skin, nasal mucosa, and upper lateral cartilage in 3 layers. Thereafter, using various nasal tip plasty techniques, the alar cartilage was reshaped and then repositioned. Patients were followed up for a mean period of 18 months. Then, the degree of subjective satisfaction of patients was analyzed with the use of 4-point visual analog scale scores. On the assessment of the degree of subjective satisfaction of patients, of a total of 502 patients, 87% responded as "very satisfactory" or "satisfactory." Through an analysis of the photographs taken before and after surgery, in patients with a short nose, the current surgical procedure was effective in extending the length of nose without the septal extension graft. The nasolabial angle was ideally expressed. Through meticulous cartilage manipulation, the tip projection improved and a bulbous shape of the nasal tip was resolved. In an aesthetic rhinoplasty for Asians, if plastic surgery of the nasal tip should be performed using a three-dimensional dissection of the alar cartilage, it would be helpful for surgeons to effectively and freely manipulate the alar cartilage according to their plans.

    Evaluation of alar traumatic injuries by using MR imaging is frequently performed. This study investigates the variability of morphology and signal intensity of alar ligaments in healthy volunteers so that pathology can be more accurately defined. Fifty healthy volunteers were examined on a 1.5T MR imaging scanner with 2-mm PD-weighted sequences in 3 planes. Delineation of the alar ligaments in 3 planes and signal-intensity characteristics on sagittal planes were analyzed by using a 4-point grading scale. Variability of courses and morphologic characteristics were described. Delineation of alar ligaments was best viewed in the coronal plane, followed by the sagittal and axial planes. In the sagittal view, 6.5% of alar ligaments appeared homogeneously dark. Hyperintense signal intensity in up to one-third of the cross-sectional area was present in 33% of cases; in up to two-thirds of the cross-sectional area, in 45% of cases; and in more than two-thirds of the cross-sectional area, in 15% of cases. Of alar ligaments, 58.5% ascended laterally, 40.5% ran horizontally, and 1% descended laterally. The cross-sectional area was round in 41.5%, oval in 51.5%, and winglike in 6.5%. On 1.5T MR imaging, the alar ligaments can be delineated best in the coronal and sagittal planes. Our data indicate a remarkable variability of morphology and course as well as signal intensity. This finding is contradictory to former publications assigning such alterations exclusively to patients with trauma.

    The aim of this study was to evaluate the accuracy of three-dimensional (3D) soft tissue simulation of nose width changes following bimaxillary osteotomies and to identify patient- and surgery-related factors that may affect the accuracy of simulation. Sixty patients (mean age 26 years) who underwent bimaxillary osteotomies participated in this study. Cone beam computed tomography scans were acquired preoperatively and at 1-year postoperative. The 3D hard and soft tissue rendered preoperative and postoperative virtual head models were superimposed, after which the maxilla and mandible were segmented and aligned to the postoperative position. The postoperative changes in alar width were simulated using a mass tensor model (MTM)-based algorithm and compared with the postoperative outcome. 3D cephalometric analyses were used to quantify the simulation error. The postoperative alar width was increased by 1.6±1.1mm and the mean error between the 3D simulation and the actual postoperative alar width was 1.0±0.9mm. The predictability was not correlated to factors such as age, sex, alar cinch suture, VY closure, maxillary advancement, or a history of surgically assisted rapid maxillary expansion. The MTM-based simulation model of postoperative alar width change was found to be reasonably accurate, although there is room for further improvement.

    Patients perceive the pulling of a nasal splints as the most feared and stressful part of nasal surgery. Even the incisions made for alar base surgery can partly or entirely dehisce. So, we have been using modified Doyle silicone splints. We compared the modified Doyle silicone splints with conventional Doyle silicone splint. Included in the study were 64 patients undergoing alar base surgery together with open septorhinoplasty. Group 1 (n = 32) patients received a conventional Doyle intranasal silicone splint and group 2 (n = 32) received modified splint that we call a hemi-split Doyle splint. The pain felt by the patients during the removal of the splints was recorded according to the visual analogue scale (VAS). On days two and four postoperatively, the nasal stuffiness score (NOSE) was recorded. On day four postoperatively an intranasal examination was conducted to establish if dehiscence had occurred on the alar base incision line. In group 2, the pain scores during splints removal were significantly lower than those in group 1. Whereas no dehiscence on the alar base incision line was observed after tampon removal in group 2, the incision dehisced in eight patients in group 1. The NOSE scores on postoperative days two and four showed no difference between the groups. The hemi-split Doyle splint causes less pain during removal and particularly does not lead to dehiscence of incisions made during alar base surgery in rhinoplasty patients.

    To compare effects of secondary cleft procedures on alar base position and nostril morphology. Retrospective review. Multidisciplinary cleft clinic at tertiary center. Seventy consecutive patients with unilateral clefts were grouped according to secondary procedure. Alveolar bone graft versus total lip takedown with anatomic muscle repair versus single-stage total lip with cleft septorhinoplasty (nose-lip) versus rhinoplasty alone. Anthropometric measurements were recorded from pre- and postoperative photographs. Ratios of cleft to noncleft side were compared within and across groups pre- and postoperatively using parametric and nonparametric tests. Within the bone graft group, no differences were seen postoperatively in alar base position in long-term follow-up. The total lip group demonstrated greater symmetry at the alar base (P alar base support (P alar base symmetry on worm's-eye view (P Alar base asymmetry in patients with unilateral clefts may be related to soft tissue deficiency and was not affected by alveolar bone grafting. Total lip takedown with anatomic muscle reapproximation was associated with increased alar base symmetry and vertical lip dimension on cleft to noncleft side. Greatest symmetry at the alar base was seen following single-stage nose-lip reconstruction, which may be an effective technique for correcting the secondary cleft lip nasal deformity.

    During forensic facial reconstruction, facial features may be predicted based on the parameters of the skull. This study evaluated the relationships between alar cartilage and piriform aperture and nose morphology and facial typology. Ninety-six cone beam computed tomography images of Brazilian subjects (49 males and 47 females) were used in this study. OsiriX software was used to perform the following measurements: nasal width, distance between alar base insertion points, lower width of the piriform aperture, and upper width of the piriform aperture. Nasal width was associated with the lower width of the piriform aperture, sex, skeletal vertical pattern of the face, and age. The current study contributes to the improvement of forensic facial guides by identifying the relationships between the alar cartilages and characteristics of the biological profile of members of a population that has been little studied thus far. © 2017 American Academy of Forensic Sciences.

    Nasal vestibular stenosis can result in a challenging cosmetic deformity, for which a variety of techniques have been described, including scar excision and replacement with local flaps, composite or cartilage grafts, with or without stents. We describe the Z-plasty technique to widen the alar base and assess patient satisfaction from the surgery. A retrospective review of patients who underwent Z-plasty to the alar subunit for nasal vestibular stenosis over a 4-year period was conducted. Demographic data and patient satisfaction were evaluated using pre- and postoperative visual analog scores and Rhinoplasty Outcome Evaluation questionnaires. Eight patients underwent the procedure, and all confirmed significant improvement in their esthetic outcome. We describe our Z-plasty technique to the alar base and review patient satisfaction.

    The D0 values for AlH 2 and AlAr are computed using the coupled cluster approach in conjunction with large basis sets. Basis set superposition and spin-orbit effects are accounted for, as they are significant due to the small binding energy. The computed dissociation energy ( D0) for AlAr is 114 cm -1, which is 93% of the experimental value (122.4 cm -1). Our best estimate for the AlH 2 binding energy is 38 ± 26 cm -1.

    Injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. One of the most common materials used is hyaluronic acid (HA) that is safe and temporary filler for soft tissue augmentation. We present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following HA injection to the nasolabial folds. She suffered from pain, necrosis, infection, and alar loss that finally required a reconstructive surgery for cosmetic appearance of the nose. The case highlights the importance of proper injection technique by an anesthesiologist, as well as the need for immediate recognition and treatment of vascular occlusion. PMID:25606480

    Langer, Martin F.; Roldán, J. Camilo

    2017-01-01

    Background: The ala of the nose is vascularized by a dense net of perforators originating from the lateral nasal artery or the angular artery. These vessels reach the ala in a cascade fashion from the alar groove/lateral nasal wall. Based on these vessels, a V/Y flap can be dissected with a wide range of mobility. Materials and Methods: Nineteen patients underwent reconstruction of the nose by means of a V/Y-alar-perforator flap alone or in combination with a myocutaneous rotation flap from the lateral nasal wall and/or from the nasal dorsum for reconstruction of defects at the nasal tip, ala of the nose, and/or lateral nasal wall. All patients were followed up 8 months after surgery in average. Results: There was no prolonged congestion or any tissue loss. All patients presented postoperatively with excellent aesthetic results, and no nasal distortion was observed. Conclusion: The V/Y-alar-perforator flap alone or in combination with a myocutaneous rotation flap proved to be a reliable tool in the armamentarium for reconstruction of nasal tip and alar defects providing good aesthetic results.

    Congenital isolated alar defects are extremely rare, occurring in approximately 1 in 20,000 to 40,000 live births. The patients are presented here of 2 pediatric patients operated on for congenital isolated alar defect. The reconstruction of congenital isolated alar defects was made in a 3-layered fashion. The skin defects were covered using the Mutaf triangular closure technique in which 2 cutaneous local flaps are designed in an unequal Z-plasty manner. Conchal cartilage graft was used between the skin and mucosal closure to replace the missing part of the lower lateral cartilage in these patients. The early results were promising in Patient 1, but sufficient improvement was detected in the alar cartilage postoperative follow-up period in Patient 2. Hence, this patient required revision 1 to 2 years postoperatively. This technique provides excellent aesthetic and functional results, except for this problem in Tessier 2 cleft patients. The use of the Stair step flap technique with Mutaf triangle closure technique achieved cosmetically and functionally excellent results in the reconstruction and repair of a large, irregular, narrow cleft, in the inadequate rotation of the lateral part of the lower lateral cartilage. However, because of this problem, evaluation of the long-term follow-up of patients is necessary.

    The aim of this study was to clarify the morphology and topography of the dilator naris vestibularis, dilator naris anterior, and alar part of the nasalis. Anatomical variations in the topographic relationships are also described to provide critical data for understanding nasal muscular functions. Anatomical and histological examinations were performed on 40 specimens of embalmed Korean adult cadavers. The dilator naris vestibularis muscle (named by the present authors) was located between the external and vestibular skin of the alar lobule. The muscle fibers radiated along the dome-shaped nasal vestibule. The dilator naris anterior muscle originated from the frontal surfaces of the lateral half of the lateral crus and the accessory alar cartilage adjacent to the lateral crus. The extent of the lower insertion of the dilator naris anterior muscle was at the alar groove. The alar part of the nasalis originated with the transverse part of nasalis from the maxilla. It ascended to attach to the alar crease and the adjacent deep surface of external skin of the alar lobule. These findings may provide anatomical knowledge required to understand the structure and function of these nasal muscles such as during rhinoplasty or other surgery of the face.

    Rupture of the alar and transverse ligaments due to whiplash injury can lead to upper cervical spine instability and subsequent neurological deterioration. The purpose of this study was to evaluate the normal anatomical variability of the alar ligaments in asymptomatic individuals with 3-T magnetic resonance imaging (MRI) and to compare the findings with standard 1.5-T examinations. Thirty-six participants underwent 3-T and 1.5-T MRIs. Magnetic resonance imaging findings were analyzed by classifying the alar ligaments with regard to the features detectability, signal intensity compared with muscle tissue, homogeneity, shape, spatial orientation, and symmetry. Delineation of the alar ligaments was significantly better on 3-T images, which were subjectively preferred for evaluation. The alar ligaments showed great variability. In the majority of participants, the alar ligaments were hypointense to muscle tissue, inhomogeneous, and different in shape and orientation. A statistically significantly higher number of ligaments appeared symmetric on 3-T imaging, indicating that 1.5-T imaging may underestimate the proportion of patients with normal, symmetric ligaments. This study demonstrates that high-field 3-T MRI provides better visualization of the alar ligaments compared with 1.5-T MRI. The higher signal-to-noise ratio allows detection of small signal changes. A great interindividual variety of the MRI morphology of the alar ligaments was found in participants with no history of neck trauma. Further studies with more participants are necessary to evaluate alar ligament pathologies in patients with a history of whiplash injury. Copyright 2012, SLACK Incorporated.

    The purpose of this study was to investigate the effects of alar base cinch suture in Le Fort I osteotomy in mandibular prognathism with and without asymmetry. Forty patients who underwent Le Fort I osteotomy were divided into an asymmetry group and a symmetry group (n = 20 each). Computed tomography (CT) was taken in all patients before and 1 year after surgery. The CT-3D volume rendering data with Aquarius Net (TeraRecon, Foster City, CA, USA) was reconstructed and the soft tissue was measured as follows, the distance between the bilateral alar base (Alar base width), the distance between the bilateral alar (Alar width), the angles between the FH plane and the line between the bilateral alar base (Alar base angle), the angle between the FH plane and the line between the bilateral alar (Alar angle), the angle between the FH plane and the line between the bilateral corners of the mouth (Lip angle), and the angle between the perpendicular line to the FH plane and the Philtrum (Philtrum angle). Significant differences were observed in the Alar width (P = 0.0448), the Alar angle (P = 0.0044), the Lip angle (P alar base cinch suture could prevent increases in the alar base width in both groups and help to improve the angle of soft tissue in the asymmetry group, although alar width significantly increases after surgery.

    The patterns of expression of a set of conserved developmental regulatory transcription factors and neuronal markers were analyzed in the alar hypothalamus of Xenopus laevis throughout development. Combined immunohistochemical and in situ hybridization techniques were used for the identification of subdivisions and their boundaries. The alar hypothalamus was located rostral to the diencephalon in the secondary prosencephalon and represents the rostral continuation of the alar territories of the diencephalon and brainstem, according to the prosomeric model. It is composed of the supraoptoparaventricular (dorsal) and the suprachiasmatic (ventral) regions, and limits dorsally with the preoptic region, caudally with the prethalamic eminence and the prethalamus, and ventrally with the basal hypothalamus. The supraoptoparaventricular area is defined by the orthopedia (Otp) expression and is subdivided into rostral and caudal portions, on the basis of the Nkx2.2 expression only in the rostral portion. This region is the source of many neuroendocrine cells, primarily located in the rostral subdivision. The suprachiasmatic region is characterized by Dll4/Isl1 expression, and was also subdivided into rostral and caudal portions, based on the expression of Nkx2.1/Nkx2.2 and Lhx1/7 exclusively in the rostral portion. Both alar regions are mainly connected with subpallial areas strongly implicated in the limbic system and show robust intrahypothalamic connections. Caudally, both regions project to brainstem centers and spinal cord. All these data support that in terms of topology, molecular specification, and connectivity the subdivisions of the anuran alar hypothalamus possess many features shared with their counterparts in amniotes, likely controlling similar reflexes, responses, and behaviors.

    Cephalically malpositioned lateral crura are a frequent cause of alar rim retraction during both primary and revision rhinoplasty. To demonstrate the efficacy of lateral crural repositioning as an isolated maneuver as and combined with adjunctive grafts for lowering the alar rim. From August through December 2014, we retrospectively reviewed the cases of 54 patients (102 hemi-noses) who had lateral crural repositioning performed by the same surgeon between 2007 and 2013. Only patients with standardized photographs taken preoperatively and at least 6 months postoperatively were included in the study. All primary and revision cases were completed via an open rhinoplasty approach and had lateral crural repositioning performed. Preoperative and postoperative photographs were compared using Adobe Photoshop CS via a modified Gunter technique to measure the degree of alar rim retraction on lateral views. The change in angle was then calculated, and statistical analysis conducted using a paired t test. A total of 54 patients (102 hemi-noses) met inclusion criteria; 42 (79%) were women, and the average patient age was 41.3 years. Forty-five (83%) of the cases were revision rhinoplasties, and the average time to obtaining postoperative photographs was 11.3 months. The mean (SD) anterior nostril apex angles preoperatively (31.3° [8.9°]) and postoperatively (24.5° [6.8°]) indicated a net decrease of 6.8° (P alar rim and/or composite grafts), we saw a similar result comparing preoperative (31.1° [8.2°]) and postoperative (24.5° [6.7°]) angles, with a net decrease of 6.6° degrees (P alar rim. Our data suggest that when combined with lateral crural repositioning, the addition of adjunctive grafts does not add significantly to the rim-lowering effect. 3.

    The hypothalamus is an important physiologic center of the vertebrate brain involved in the elaboration of individual and species survival responses. To better understand the ancestral organization of the alar hypothalamus we revisit previous data on ScOtp, ScDlx2/5, ScTbr1, ScNkx2.1 expression and Pax6 immunoreactivity jointly with new data on ScNeurog2, ScLhx9, ScLhx5, and ScNkx2.8 expression, in addition to immunoreactivity to serotonin (5-HT) and doublecortin (DCX) in the catshark Scyliorhinus canicula, a key species for this purpose since cartilaginous fishes are basal representatives of gnathostomes (jawed vertebrates). Our study revealed a complex genoarchitecture for the chondrichthyan alar hypothalamus. We identified terminal (rostral) and peduncular (caudal) subdivisions in the prosomeric paraventricular and subparaventricular areas (TPa/PPa and TSPa/PSPa, respectively) evidenced by the expression pattern of developmental genes like ScLhx5 (TPa) and immunoreactivity against Pax6 (PSPa) and 5-HT (PPa and PSPa). Dorso-ventral subdivisions were only evidenced in the SPa (SPaD, SPaV; respectively) by means of Pax6 and ScNkx2.8 (respectively). Interestingly, ScNkx2.8 expression overlaps over the alar-basal boundary, as Nkx2.2 does in other vertebrates. Our results reveal evidences for the existence of different groups of tangentially migrated cells expressing ScOtp, Pax6, and ScDlx2. The genoarchitectonic comparative analysis suggests alternative interpretations of the rostral-most alar plate in prosomeric terms and reveals a conserved molecular background for the vertebrate alar hypothalamus likely acquired before/during the agnathan-gnathostome transition, on which Otp, Pax6, Lhx5, and Neurog2 are expressed in the Pa while Dlx and Nkx2.2/Nkx2.8 are expressed in the SPa.

    The aim of this prospective randomized control trial was to analyse the efficacy of a new trans-septal alar base cinch suture in controlling alar width in patients undergoing maxillary intrusion and setback by comparing it with the traditional cinch suture. Statistical evaluation was carried out in 62 of 76 patients. Group I (31 patients) received the traditional alar base cinch suture, and group II (31 patients) received the alar base cinch suture with an anchoring bite taken through the nasal septum 10mm behind its anterior edge. In both groups the accurate identification of alar fibroareolar tissue was facilitated by an 18 gauge green needle passed extra orally. Alar base width was measured before and 6 months after surgery using Vernier callipers. Preoperative alar base width for group I was 29.76 mm (1.901SD) and for group II 29.79 mm (3.141SD); the postoperative values were 32.42 mm (1.858SD) and 29.94 mm (2.568SD), respectively. Mean alar base widening was 2.661 mm (0.800SD) in group I and 0.145 mm (2.050) in group II. The difference in alar widening was statistically significant (palar cinch suture offers better control of alar base architecture in maxillary intrusion and setback.

    To investigate the technique and its effect of combined nasolabial flap and free auricular composite flap for full-thickness nasal alar defect. From March 2010 to March 2013, 9 patients with full-thickness nasal alar defects were treated with combined nasolabial flaps and free auricular composite flaps. Composite auricular flap was used as inner lining and cartilage framework. The nasolabial flap at the same side was used as outer lining. All the patients were followed up for 6-18 months (average, 12 months). All the 9 composite auricular flaps survived completely. Epidermal necrosis happened at the distal end of 1 nasolabial flap. Alar rim was almost normal and symmetric nose was achieved in 6 cases. The arc and the thickness of the alar rim was not enough in 3 cases, resulting in asymmetric appearance. The survival area of auricular composite flap can be enlarged with nasolabial flap. The auricular helix edge can be reserved to reconstruct nasal alar rim with smooth and natural arc. Large full-thickness nasal alar defedts can be reconstructed with combined nasolabial flaps and free auricular composite flaps.

    Nasolabial flaps have been widely used for nasal reconstruction. However, transposition of the nasolabial flap to lower nasal defects may be challenging because of functional and aesthetic concerns. The upper part of the alar crease joins with the nasolabial fold seamlessly, forming the nasolabial-alar crease line, which provides a natural strategy for easy concealment of the surgical scar. In this article, we would like to introduce a method for transferring a nasolabial flap along the nasolabial-alar crease to reconstruct lower nasal defects. Incision was made along the nasolabial-alar crease, and the nasolabial flap was transferred for lower nasal reconstruction in 9 patients. Subcutaneously based nasolabial flaps were designed, and undermining of the superolateral skin was made along the nasolabial-alar crease to obtain a robust subcutaneously based pedicle, so as to readily achieve flap transposition without tension and concealment of the subcutaneous pedicle. The nasolabial fold could be reproduced by closing the donor site. Lower nasal defects were successfully repaired with nasolabial flap in 9 patients. Good nasal contour and appropriate symmetry of the reconstructed nasolabial fold were achieved, and there were no conspicuous scars in the 9 cases. The natural nasolabial-alar crease can serve as a useful incision line to facilitate the nasolabial flap transposition for lower nasal reconstruction while minimizing the scar.

    Spectra of jet-cooled AlAr and AlKr have been collected over the range from 31 000 cm-1 to the ionization limit, using the technique of resonant two-photon ionization spectroscopy with mass spectrometric detection. Adiabatic ionization potentials have been accurately measured for both molecules, and have been estimated for AlAr2 and AlAr3. The spin-orbit splittings in the X 2Π ground state have been determined for both AlAr and AlKr, and ground-state bond strengths have been accurately measured as D0[AlAr, X1 2Π1/2(3p)] =122.4±4 cm-1 and D0[27Al 84Kr, X1 2Π1/2(3p)] =194.7±0.8 cm-1. These values have also been combined with the measured ionization potentials to derive D0(Al+-Ar)=982.3± 5 cm-1 and D0(Al+-Kr)=1528.5±2 cm-1.

    Ligamentous calcification of the cervical spine has been reported in the yellow ligament, anterior and posterior longitudinal ligaments and interspinous ligament. Calcification in the upper cervical spine is rare, although some cases with calcification of the transverse ligament of the atlas have been reported. Two patients with calcification of the alar ligament with an unusual clinical presentation and course are described. Examination by tomography and computed tomography (CT) showed calcification of the alar ligament and the transverse ligament of the atlas. CT documented decreased calcification as symptoms resolved. There may be a role for CT in the search for calcifications in the upper cervical spine in patients presenting with neck pain and pharyngodynia if radiographs are normal. (orig.)

    Ligament disruptions at the craniovertebral junction are typically associated with atlantoaxial rotatory dislocation during upper cervical spine injuries and require external orthoses or surgical stabilization. Only in few patients isolated ruptures of the alar ligament have been reported. Here we present a further case, in which the diagnosis was initially obscured by a misleading clinical symptomatology but finally established six month following the trauma, demonstrating the value of contrast-enhanced high resolution 3 Tesla magnetic resonance imaging in identifying this particular lesion.

    To many surgeons, nasal airway obstruction is synonymous with either septal deviation or inferior turbinate hypertrophy. The role of internal and external nasal valves is often less known by surgeons even if it is crucial in nasal breathing and strongly interrelated with esthetic of the middle third of the nose and alar wall. Therefore, precise examination of the two valves and conservative surgery should help to avoid many functional and esthetic problems. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    The droopy tip is a common nasal deformity in which the tip is inferiorly rotated. Five hundred consecutive rhinoplasty cases were studied to assess the incidence and causes of the droopy tip deformity and to evaluate the role of three alar cartilage-modifying techniques--lateral crural steal, lateral crural overlay, and tongue in groove--in correcting such a deformity. The external rhinoplasty approach was used in all cases. Only one of the three alar cartilage-modifying techniques was used in each case, and the degree of tip rotation and projection was measured both preoperatively and postoperatively. The incidence of droopy tip was 72 percent, and the use of an alar cartilage-modifying technique was required in 85 percent of these cases to achieve the desired degree of rotation. The main causes of droopy tip included inferiorly oriented alar cartilages (85 percent), overdeveloped scrolls of upper lateral cartilages (73 percent), high anterior septal angle (65 percent), and thick skin of the nasal lobule (56 percent). The lateral crural steal technique increased nasal tip rotation and projection, the lateral crural overlay technique increased tip rotation and decreased tip projection, and the tongue-in-groove technique increased tip rotation without significantly changing the amount of projection. The lateral crural overlay technique resulted in the highest degrees of rotation, followed by the lateral crural steal and finally the tongue-in-groove technique. According to these results, the lateral crural steal technique is best indicated in cases with droopy underprojected nasal tip, the lateral crural overlay technique in cases of droopy overprojected nasal tip, and the tongue-in-groove technique in cases where the droopy nasal tip is associated with an adequate amount of projection.

    The repair of full-thickness nasal alar defects presents difficulties because of their complex 3-dimensional structure. Reconstructions using inappropriate methods may lead to asymmetries and dissatisfying functional results. In this study, our aim was to present the repairs of full-thickness alar defects performed using cartilage-supported nasolabial perforator flaps. Eight patients who presented to our clinic between January 2011 and April 2014 with full-thickness defects in the alar wings were included in this study. The nasolabial perforator flap was prepared on the basis of the closest perforator to the defect area and in a way to include 2 to 3 mm of subcutaneous adipose tissue. The medial section of the flap was adapted to form the nasal lining. In the 7 patients in whom cartilage support was used, the cartilage graft was obtained from the septum nasi. After the cartilage was placed on the flap, the lateral section of the flap was folded over the medial section and the defect was repaired. In 1 patient in whom cartilage support was not required, the flap was folded over itself before the repair was performed. The flap donor area was primarily repaired. No detachment around the suture lines, infection, venous insufficiency in the flap, or partial or total flap losses were observed in any of the patients. Retraction developed in 1 patient in whom no cartilage support was used. No retraction was observed in any of the patients in whom cartilage support was used. The results were functionally and esthetically satisfying in all the patients. The greatest advantage of perforator-based nasolabial flaps is the greater mobilization achieved in comparison with the other nasolabial flaps. Thus, full-thickness defects can be repaired in 1 session in some patients, no revision is required around the flap pedicle, and much less donor area morbidity occurs. Nasal alar reconstructions performed using this type of flap lead to both esthetically and functionally satisfying

    The aim of our study was to investigate the 5-year outcomes of children with neuromuscular scoliosis treated with sacral-alar-iliac screws. We reviewed clinical and radiographic records of patients ≤18 years old treated by 1 pediatric orthopaedic surgeon for neuromuscular scoliosis with spinal fusion using sacral-alar-iliac pelvic anchors. Thirty-eight patients, with a minimum 5-year radiographic follow-up (6.0 ± 1.2 years), were studied. Mean patient age was 13 ± 2.0 years and 47% were female. The mean number of levels fused was 18 ± 0.7. The diagnosis was cerebral palsy in 66% of patients. Between the preoperative period and final follow-up there was a mean 79% correction of the major coronal curve (85° to 18°) and 57% correction of the pelvic obliquity (16° to 7°). Patients maintained correction of mean pelvic obliquity from the early postoperative period (6°) to final follow-up (7°). Preoperatively, 76% of patients had pelvic obliquity of >10°compared with 26% after surgery. There were no cases of neurologic or vascular complications or pseudarthrosis. Radiographs revealed bilateral sacral-alar-iliac screw lucency in 8 patients; 4 of these patients had deep wound infections, and the other 4 were asymptomatic. Unilateral screw fracture was found in 1 patient with an 8-mm screw diameter (1.3%, 1 of 76 screws); the patient was observed and remained asymptomatic. There were no cases of set screw displacement, screw back-out, or rod dislodgement. Sacral-alar-iliac screws are safe and effective pelvic anchors for use in children with neuromuscular scoliosis.

    Mistranslation arising from confusion of serine for alanine by alanyl-tRNA synthetases (AlaRSs) has profound functional consequences. Throughout evolution, two editing checkpoints prevent disease-causing mistranslation from confusing glycine or serine for alanine at the active site of AlaRS. In both bacteria and mice, Ser poses a bigger challenge than Gly. One checkpoint is the AlaRS editing centre, and the other is from widely distributed AlaXps-free-standing, genome-encoded editing proteins that clear Ser-tRNA(Ala). The paradox of misincorporating both a smaller (glycine) and a larger (serine) amino acid suggests a deep conflict for nature-designed AlaRS. Here we show the chemical basis for this conflict. Nine crystal structures, together with kinetic and mutational analysis, provided snapshots of adenylate formation for each amino acid. An inherent dilemma is posed by constraints of a structural design that pins down the alpha-amino group of the bound amino acid by using an acidic residue. This design, dating back more than 3 billion years, creates a serendipitous interaction with the serine OH that is difficult to avoid. Apparently because no better architecture for the recognition of alanine could be found, the serine misactivation problem was solved through free-standing AlaXps, which appeared contemporaneously with early AlaRSs. The results reveal unconventional problems and solutions arising from the historical design of the protein synthesis machinery.

    Surgical reconstruction of cartilaginous defects remains a major challenge. In the current study, we aimed to identify an imaging strategy for the development of patient-specific constructs that aid in the reconstruction of nasal deformities. Magnetic Resonance Imaging (MRI) was performed on a human cadaver head to find the optimal MRI sequence for nasal cartilage. This sequence was subsequently used on a volunteer. Images of both were assessed by three independent researchers to determine measurement error and total segmentation time. Three dimensionally (3D) reconstructed alar cartilage was then additively manufactured. Validity was assessed by comparing manually segmented MR images to the gold standard (micro-CT). Manual segmentation allowed delineation of the nasal cartilages. Inter- and intra-observer agreement was acceptable in the cadaver (coefficient of variation 4.6-12.5%), but less in the volunteer (coefficient of variation 0.6-21.9%). Segmentation times did not differ between observers (cadaver P = 0.36; volunteer P = 0.6). The lateral crus of the alar cartilage was consistently identified by all observers, whereas part of the medial crus was consistently missed. This study suggests that MRI is a feasible imaging modality for the development of 3D alar constructs for patient-specific reconstruction.

    Repositioning the medial crura cephalically onto the caudal septum (tongue-in-groove; TIG) allows alteration of the columella, ala, and nasal tip to address alar-columellar disproportion as seen from the lateral view. To date, quantitative analysis of nostril dimension, alar-columellar relationship, and nasal tip changes following the TIG rhinoplasty technique have not been described. The present study aims to evaluate post-operative lateral morphometric changes following TIG. Pre- and post-operative lateral views of a series of consecutive patients who underwent TIG rhinoplasty were produced from 3D images at multiple time points (≤2 weeks, 4-10 weeks, and >10 weeks post-operatively) for analysis. The 3D images were converted to 2D and set to scale. Exposed lateral nostril area, alar-columellar disproportion (divided into superior and inferior heights), nasolabial angle, nostril height, and nostril length were calculated and statistically analyzed using a pairwise t test. A P ≤ 0.05 was considered statistically significant. Ninety-four lateral views were analyzed from 20 patients (16 females; median age: 31.8). One patient had a history of current tobacco cigarette use. Lateral nostril area decreased at all time points post-operatively, in a statistically significant fashion. Alar-columellar disproportion was reduced following TIG at all time points. The nasolabial angle significantly increased post-operatively at ≤2 weeks, 4-10 weeks, and >10, all in a statistically significant fashion. Nostril height and nostril length decreased at all post-operative time points. Morphometric analysis reveals reduction in alar-columellar disproportion and lateral nostril shows following TIG rhinoplasty. Tip rotation, as a function of nasolabial angle, also increased. These results provide quantitative substantiation for qualitative descriptions attributed to the TIG technique. Future studies will focus on area and volumetric measurements, and assessment of long

    Among the many secondary deformities in cleft-lip nose, the alar-columella web is unsightly and is a recurrent deformity. The purpose of this article is to revisit the correction of alar web deformity in patients with cleft-lip nasal deformities and to introduce our web graft technique. Thirteen patients with alar webbing underwent surgery between June 2012 and February 2013. The age range of the patients at the time of surgery was 14-29 years. An open rhinoplasty incision, including a reverse-U incision, was made and cartilage work was performed. After the cleft side was equalized with the dome angle of the healthy side, we used contralateral alar or auricular cartilage grafts as a stiff batten to stabilize the converted web skin. The web graft was fixed to the cleft-side web skin's inner side with at least three sutures to maintain the tucking of the vestibular skin. The follow-up period ranged from 1 to 20 months. The postoperative frontal and basal views showed that the nostrils and columella had better shape. Most patients demonstrated correction of the drooping alar rim and satisfactory symmetry of the nostrils. A web graft supports the vestibular lining of the reverse-U incision and increases the strength of the new concavity of the tucked skin. We expect that a long-lasting concave web contour could be achieved with this technique.

    Background Among the various methods for correcting nasal deformity, the composite graft is suitable for the inner and outer reconstruction of the nose in a single stage. In this article, we present our technique for reconstructing the ala and columella using the auricular chondrocutaneous composite graft. Methods From 2004 to 2011, 15 cases of alar and 2 cases of columellar reconstruction employing the chondrocutaneous composite graft were studied, all followed up for 3 to 24 months (average, 13.5 months). All of the patients were reviewed retrospectively for the demographics, graft size, selection of the donor site and outcomes including morbidity and complications. Results The reasons for the deformity were burn scar (n=7), traumatic scar (n=4), smallpox scar (n=4), basal cell carcinoma defect (n=1), and scar contracture (n=1) from implant induced infection. In 5 cases of nostril stricture and 6 cases of alar defect and notching, composite grafts from the helix were used (8.9×12.5 mm). In 4 cases of retracted ala, grafts from the posterior surface of the concha were matched (5×15 mm). For the reconstruction of the columella, we harvested the graft from the posterior scapha (9×13.5 mm). Except one case with partial necrosis and delayed healing due to smoking, the grafts were successful in all of the cases and there was no deformity of the donor site. Conclusions An alar and columellar defect can be reconstructed successfully with a relatively large composite graft without donor site morbidity. The selection of the donor site should be individualized according to the 3-dimensional configuration of the defect. PMID:22872834

    Composite grafts for nasal reconstruction have been around for over a century but the opinion on its virtues and failings keeps vacillating with a huge difference on the safe size of the graft for transfer. Alar margin and columellar defects are more distinct than dorsal nasal defects in greater difficulty in ensuring a good aesthetic outcome. We report our series of 19 consecutive patients in whom a composite graft was used to reconstruct a defect of alar margin (8 patients), alar base (7 patients) or columella (4 patients). Patient ages ranged from 3-35 years with 5 males and 14 females. The grafts to alar margin and base ranged 0.6-1 cm in width, while grafts to columella were 0.7-1.2 cm. The maximum dimension of the graft in this series was 0.9 mm x 10 mm. Composite grafts were sculpted to be two layered (skin + cartilage), three layered wedges (skin + cartilage + skin) or their combination (two layered in a portion and three layered in another portion). All grafts were cooled in postoperative period for three days by applying an indigenous ice pack of surgical glove. The follow up ranged from 3-9 months with an average of 4.5 months. All of our 19 composite grafts survived completely but they all shrank by a small percentage of their bulk. Eleven patients rated the outcome between 90-95% improvement. We noticed that composite grafts tended to show varied pigmentation in our patients, akin to split skin grafts. In our opinion, most critical to graft survival is its size and the ratio of the marginal raw area to the graft bulk. We recommend that graft width should not exceed 1 cm to ensure complete survival even though larger sized grafts have been reported to survive. We recommend cooling of the graft and justify it on the analogy of 'warm ischemia time' for a replantation, especially in warmer climes like ours in India. We have outlined several considerations in the technique, with an analysis of differing opinions that should facilitate a surgeon in making an

    The cause and clinical relevance of upper neck ligament high signal intensity on MR imaging in WAD are controversial. The purpose of this study was to explore changes in the signal intensity of the alar and transverse ligaments during the first year after a whiplash injury. Dedicated high-resolution upper neck proton attenuation-weighted MR imaging was performed on 91 patients from an inception WAD1-2 cohort, both in the acute phase and 12 months after whiplash injury, and on 52 controls (noninjured patients with chronic neck pain). Two blinded radiologists independently graded alar and transverse ligament high signal intensity 0-3, compared initial and follow-up images to assess alterations in grading, and solved any disagreement in consensus. The Fisher exact test was used to compare proportions. Alar and transverse ligament grading was unchanged from the initial to the follow-up images. The only exceptions were 1 alar ligament changing from 0 to 1 and 1 ligament from 1 to 0. The prevalence of grades 2-3 high signal intensity in WAD was thus identical in the acute phase and after 12 months, and it did not differ from the prevalence in noninjured neck pain controls (alar ligaments 33.0% versus 46.2%, P = .151; transverse ligament 24.2% versus 23.1%, P = 1.000). Alar and transverse ligament high signal intensity in patients with WAD1-2 observed within the first year after injury cannot be explained by the trauma. Dedicated upper neck MR imaging cannot be recommended as a routine examination in these patients.

    Knowing the operation plan is important for rhinoplasty surgeons to prevent unpredictable results. To investigate the frequency of alar base resection in patients with different skin thickness who underwent lateral crural repositioning and lateral crural strut graft and to evaluate the results in the context of the current literature. This retrospective case series study included 621 patients who underwent primary open septorhinoplasty by the same surgeon between January 1, 2012, and June 30, 2015. From the surgical notes, operation type (lateral crural repositioning [LCrep] with lateral crural strut grafting [LCSG] and with or without alar base resection) and skin type were recorded. Study participants' skin types were determined intraoperatively and divided into 3 groups: (1) thick skin (the tip definition was limited by skin thickness and subcutaneous tissue), (2) thin skin (the tip cartilage was visible and could be observed despite overlying soft tissue and skin), and (3) normal skin (the tip cartilage during the procedure had no effect on the tip definition). Of the 621 patients in the study, 95 (15.3%) were men and 526 (84.7%) were women. Lateral crural repositioning with LCSG was performed in 319 surgical procedures (51.4%), and alar base reduction was performed in 329 (53.0%). The rate of alar base resection differed significantly on the basis of whether LCrep with LCSG was performed (odds ratio [OR], 1.82; 95% CI, 1.32-2.50; P alar base resection associated with LCrep with LCSG (OR, 2.034; 95% CI, 0.912-4.539; P = .08). In patients with thick skin, a significant difference in the frequency of alar base resection was associated with the application of LCrep with LCSG (OR, 1.995; 95% CI, 1.228-3.241; P = .005). In patients with normal skin, LCrep with LCSG had no significant association with the frequency of alar base resection (OR, 1.557; 95% CI, 0.930-2.607; P = .09). The necessity of alar base reduction after LCrep with LCSG is greater in

    During the formation of brain nuclei, the vertebrate neural tube is partitioned into distinct embryonic divisions. In this study, the expression of three members of the cadherin family of adhesion molecules (cadherin-6B, cadherin-7, and R-cadherin) was mapped to study the differentiation of gray matter in the division so that diencephalic alar plate of chicken embryos from embryonic day 3 (E3) to E10. At early stages of development (E3-E4), each cadherin is expressed in restricted regions of the diencephalic wall of the neural tube. The borders of some of the expression domains coincide with divisional boundaries. As the mantle layer is formed and increases in thickness from E4 to E8, morphologically discernible aggregates of cells appear that express the three cadherins differentially. These aggregates represent the anlagen of specific diencephalic brain nuclei, e.g., the lateroanterior nucleus, the ventral geniculate nucleus, the nucleus rotundus, the perirotundic area, the principal precommissural nucleus, and the lateral spiriform nucleus. Most of the cadherin-expressing diencephalic nuclei studied in this work apparently derive from a single embryonic division and remain there. The divisional boundaries are replaced gradually by the borders of cadherin-expressing brain nuclei. The current results support the idea that cadherins confer differential adhesiveness to developing structures of gray matter in the diencephalic alar plate. Moreover, they suggest that each cadherin plays a role in the formation of specific brain nuclei within the diencephalic divisions.

    Pinched nasal point can be arising as congenital malformation or as results of unsuccessfully surgery. The nasal valve alteration due to this problem is not only an esthetic problem but also a functional one because can modify the nasal airflow. Several surgical techniques were proposed in literature, we proposed our. The purpose of the study is the evaluation of nose airway flow using our flip-flap technique for correction of pinched nasal tip. This is a retrospective study conducted on twelve patients. Tip cartilages were remodeled by means of autologous alar cartilage grafting. The patients underwent a rhinomanometry pre and post-surgery to evaluate the results, and they performed a self-survey to evaluate their degree of satisfaction in term of airflow sensation improvement. Rhinomanometry showed improved nasal air flow (range from 25% to 75%) in all patients. No significant differences were showed between unilateral and bilateral alar malformation (p=0.49). Patient's satisfaction reached the 87.5%. Our analysis on the combined results (rhinomanometry and surveys) showed that this technique leads to improvement of nasal flow in patients affected by pinched nasal tip in all cases.

    2002-01-01

    Full Text Available Patients with unilateral cleft lip display characteristic nasal changes that are independent of the degree of deformity. Defenders of the intrinsic theory consider these deformities to be due to embryogenic alterations of the alar nasal cartilages. Those that propose the extrinsic theory defend the thesis that the deformity is due to disorganization of the perioral muscles deformed by the cleft. The purpose of this study is to contribute histological evidence to help clarify the issue. PATIENTS AND METHODS: Specimens of the lateral portion of both the healthy and the cleft side of the alar cartilages were obtained from 18 patients. These uniformly cut specimens were stained by hematoxylin and eosin. Samples from 2 patients were excluded due to imperfections. The same pathologist examined all the slides. He was unaware of the origins of the specimens; he counted the number of chondrocytes and quantified the cartilage matrixes. RESULTS: All data was analyzed statistically, and no significant statistical differences were apparent, either in the number of chondrocytes or the cartilage matrix between the healthy side and the cleft side. DISCUSSION: These results apparently support the group that defend the extrinsic theory; nevertheless, the doubt about the composition of the cartilage matrix remains, not only concerning the glycosaminoglycans that compose them, but also regarding elastin and collagen and its linkages that can cause different degrees of collagen consistency.

    In the evolution of cleft lip repair, there have been continuous attempts to minimize local trauma and to improve lip and nasal appearances. In order to obtain an aesthetically balanced development of midface, the primary surgical correction of the nasolabial area is of paramount importance. In this study, the importance of a back-cut extending cephalically above the inferior turbinate at the mucocutaneous junction which elevates the nostril floor on the cleft side for the purpose of achieving symmetry of the alar bases are analyzed by pre and postoperative photographic anthropometry. This study comprised of fifty cases of the unilateral complete cleft lip. At the time of surgery, the patient age ranged from 3-9 months. The surgeries, performed by a single surgeon, employed the standard Millard technique, incorporating Mohler modifications of lip repair. Anthropometric analysis revealed that the preoperative mean difference between the normal side and the cleft side was 0.2056 with a standard deviation of 0.133. In the postoperative analysis, the mean difference was reduced to 0.0174 with a standard deviation of 0.141. The paired t-test showed that the p-value is alar base symmetry during primary surgery.

    To explore the application of alar thin expanded cervical flap with pedicle in anterior neck for large scars on middle and lower face. From February 2000 to July 2013, 26 patients with scars on the middle and lower face were treated with the alar thin expanded cervical flaps with pedicle in anterior neck. After the skin of anterior neck was expanded by implanting skin expanders, alar thin expanded cervical flap with pedicle in anterior neck was obtained with size of 163-275 cm(2). Then the scars on the middle and lower face with the size of 135-196 cm(2) were excised, with the area of excision allowing full coverage of the expanded flap. The flap was rotated and advanced to the middle and lower face, and the incision was closed in layers. The 26 patients were followed up for 2 to 24 months. Twenty-one flaps survived, with good appearance and function. Four flaps showed venous retardation at distal part, and only one flap showed necrosis of the right edge. They were healed by free skin grafting. The alar thin expanded cervical flap not only makes maximum use of expanded flap on the premise of ensuring blood supply, but also guarantees good color, texture, and contour of face and neck.

    The repair of cleft lips has an important place in plastic and reconstructive surgery. In the treatment of these deformities, the aim was to restore the normal lip morphology in the cleft area as well as repairing any coexisting nasal deformities. Various methods are in use for this purpose. One of the most commonly employed surgical methods is Millard repair. However, this method may lead to additional scarring in the alar base on the cleft side subsequent to the incision. In this study, the results obtained from a group who have been applied alar base incisions during the modified Millard repair are compared to a group who have undergone intranasal wide dissections.The patients enrolled in the study were randomized into 2 groups. The first group were applied the modified Millard repair. In the second group, the rotation, advancement, and C-flaps were prepared according to Millard surgical repair technique; however, instead of an alar base and nasofacial groove incision on the cleft side, a nasal and maxillary supraperiosteal wide dissection was made through the incision in the mucosa of the nostril.The intranasal dissection performed during the study was observed to provide the targeted outcome and a more satisfactory cosmetic result through the modified Millard repair. In conclusion, the authors are of the opinion that the limited alar base incision and the wide supraperiosteal dissection performed in patients with cleft lips is an alternative method that can be employed in a wide range of patients.

    Reconstruction of defects straddling the alar groove presents the dual challenges of resurfacing the nasal sidewall and alar subunits while simultaneously recreating the alar groove. The wave flap (WF) is a modified, medially based, nasal sidewall rotation flap that uses locally recruited tissue from the nasal sidewall to facilitate color and texture match and permit camouflage of scars. To detail a surgical repair for defects in the horizontally oriented middle third of the alar groove. This retrospective case series describes a technique for repair of defects involving the alar groove. Using postoperative photographs, outcomes were assessed by blinded noninvestigator dermatologist raters using the Observer Scar Assessment Scale. Between February 2012 and June 2013, 10 patients were reconstructed using a WF design. Subjective assessment of scar vascularity, pigment, pliability, relief, and thickness by 3 independent reviewers yielded an overall cosmesis score of 11.1 (out of 50). No complications were noted. The WF provides an excellent reconstructive option for Mohs defects of the middle third of the alar groove by recruiting local tissue and permitting maximum scar camouflage. A well-designed and executed WF provides cosmetically exceptional results for defects of the alar groove.

    In full-thickness defects of the nasal alar rim, to achieve projection and maintain airway patency, cartilage graft is frequently needed. However, cartilage graft presents a challenge in considerations such as appropriate donor site, skeletal shape and size, and healing of the donor area. To avoid these demerits, we tried primary closure of alar rim defects by also making the contralateral normal ala smaller. We treated two patients who had a full-thickness nasal alar defect after tumor excision. Cartilage graft was considered for the reconstruction. However, their alar rims were overly curved and their nostril openings were large. To utilize their nasal shape, we did primary closure of the defect rather than cartilage graft, and then downsized the contralateral nasal ala by means of wedge resection to make the alae symmetric. Both patients were satisfied with their aesthetic results, which showed a smaller nostril and nearly straight alar rims. Moreover, functionally, there was no discomfort during breathing in both patients. We propose our idea as one of the reconstruction options for nasal alar defects. It is a simple and easy-to-perform procedure, in addition to enhancing the nasal contour. This method would be useful for patients with a large nostril and an overly curved alar rim.

    Dysfunctional transverse and alar craniovertebral ligaments can cause instability and osseous destruction in rheumatoid arthritis (RA). This study examined (1) the feasibility of high-resolution magnetic resonance imaging (MRI) of these ligaments in RA and (2) the relation between ligament high-signal changes and atlantoaxial subluxation and RA duration/severity. Consecutive RA patients (n=46) underwent clinical examination, functional radiography, and high-resolution MRI. Two blinded radiologists rated MRI image quality, graded ligament high-signal changes 0-3 on proton-weighted sequences using an existing grading system, and assessed cervical spine rheumatic changes on short tau inversion recovery images. Agreement was analyzed using kappa and relations using multiple logistic regression. MRI images had good quality in 42 (91.3%) of 46 patients and were interpretable in 44 (32 women and 12 men, median age/disease duration 60.4/9.1 years). MRI grades 2-3 changes of the transverse and alar ligaments showed moderate and good interobserver agreement (kappa 0.59 and 0.78), respectively, and prevalence 31.8% and 34.1%. Such ligament changes were more frequent with increasing anterior atlantoaxial subluxation (p=0.012 transverse, p=0.028 alar), higher erythrocyte sedimentation rate (p=0.003 transverse), positive rheumatoid factor (p=0.002 alar), and neck pain (p = 0.004 alar). This first study of high-resolution MRI of these ligaments in RA showed high feasibility and relations with atlantoaxial subluxation, RA disease activity, and neck pain. The clinical usefulness of such MRI needs further evaluation. (orig.)

    The purpose of this study was to introduce a powerful technique for the treatment of kyphoscoliosis. There are currently multiple techniques for sacropelvic fixation, including trans-iliac bars and iliac and iliosacral screws. Several studies have documented the use of these instrumentation techniques; however, a ubiquitous problematic issue concerns the need for separate incisions for the use of offset connectors, which add to surgical time and morbidity. Any additional dissection of the skin, subcutaneous tissue or muscle in this area is believed to increase the incidence of complications of wound healing. However, as stated above, the above-mentioned techniques require separate incisions for the use of offset connectors, which add to surgical time and morbidity. The novel technique of S2 alar-iliac (S2AI) pelvic fixation has been developed to address some of these issues. However, a technique for achieving correction of kyphoscoliosis with pelvic obliquity in adult patients with spinal deformity has not previously been described. Our entry point is based on the S1 foramen and is typically up to 5 mm caudal and 2 to 3 mm lateral to that foramen. Once the S1 foramen has been identified, a blunt instrument can be used to probe the alar ridge. The screw trajectory is 40°-50° from horizontal and 20°-30° caudal, aimed toward the greater trochanter and rostral to the sciatic notch. A 36-year-old female patient presented with a 3-year history of low back pain, and progressive thoracolumbar kyphoscoliosis. In this typical case, we performed S2AI fixation with transforaminal lumbar interbody fusion and hemivertebra resection technique to treat her lumbosacral kyphoscoliosis. Satisfactory improvement in her preoperative lumbar kyphoscoliosis was found at 3-month follow-up. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

  20. Toward less misleading comparisons of uncertain risks: the example of aflatoxin and alar.

    1995-01-01

    Critics of comparative risk assessment (CRA), the increasingly common practice of juxtaposing disparate risks for the purpose of declaring which one is the "larger" or the "more important," have long focused their concern on the difficulties in accommodating the qualitative differences among risks. To be sure, people may disagree vehemently about whether "larger" necessarily implies "more serious," but the attention to this aspect of CRA presupposes that science can in fact discern which of two risks has the larger statistical magnitude. This assumption, encouraged by the indiscriminate calculation of risk ratios using arbitrary point estimates, is often incorrect: the fact that environmental and health risks differ in unknown quantitative respects is at least as important a caution to CRA as the fact that risks differ in known qualitative ways. To show how misleading CRA can be when uncertainty is ignored, this article revisits the claim that aflatoxin contamination of peanut butter was "18 times worse" than Alar contamination of apple juice. Using Monte Carlo simulation, the number 18 is shown to lie within a distribution of plausible risk ratios that ranges from nearly 400:1 in favor of aflatoxin to nearly 40:1 in the opposite direction. The analysis also shows that the "best estimates" of the relative risk of aflatoxin to Alar are much closer to 1:1 than to 18:1. The implications of these findings for risk communication and individual and societal decision-making are discussed, with an eye toward improving the general practice of CRA while acknowledging that its outputs are uncertain, rather than abandoning it for the wrong reasons.

    The depression of alar base in affected side in patients with unilateral complete cleft lip/palate (CL/P) is one of common clinical features. In this study, the authors try to explore the effect of subcutaneous C shape muscular flap for correcting the depression of alar base in affected side in patients with unilateral complete CL/P during primary surgery. A total of 30 patients with unilateral complete CL/P who received primary correction of the lip nose deformity were included in this study. The C flap was used to drop and lengthen the height of upper lip in unaffected side, and the subcutaneous muscular flap was dissected from the C flap and positioned at the alar base in the affected side of upper lip to correct the depression. Then the surgical effect was evaluated based on clinical examination during follow-up. Alar base symmetry was obtained in 26 patients of this case series, and 4 patients showed slight improvement in alar base symmetry. No major complications such as flap necrosis, infection, or hypertrophic scars were observed during surgery and follow-up. No additional incisions and operative time were necessary. The subcutaneous C shape muscular flap described in this article could offer enough muscular support and markedly correct the depression of nostril and alar base in affected side in primary lip nose repair with no additional incisions and operative time for patients with unilateral complete CL/P.

    OBJECTIVE To develop and assess the feasibility, repeatability, and safety of an ultrasound-guided technique to stimulate the first cervical nerve (FCN) at the level of the alar foramen of the atlas of horses. ANIMALS 4 equine cadavers and 6 clinically normal Standardbreds. PROCEDURES In each cadaver, the FCN pathway was determined by dissection, and any anastomosis between the first and second cervical nerves was identified. Subsequently, each of 6 live horses underwent a bilateral ultrasound-guided stimulation of the FCN at the alar foramen 3 times at 3-week intervals. After each procedure, horses were examined daily for 5 days. RESULTS In each cadaver, the FCN passed through the alar foramen; a communicating branch between the FCN and the accessory nerve and anastomoses between the ventral branches of the FCN and second cervical nerve were identified. The anastomoses were located in the upper third of the FCN pathway between the wing of the atlas and the nerve's entry in the omohyoideus muscle. Successful ultrasound-guided electrical stimulation was confirmed by twitching of the ipsilateral omohyoideus muscle in all 6 live horses; this finding was observed bilaterally during each of the 3 experimental sessions. No complications developed at the site of stimulation. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that ultrasound-guided stimulation of the FCN at the alar foramen appears to be a safe and straightforward procedure in horses. The procedure may have potential for use in horses with naturally occurring recurrent laryngeal neuropathy to assess reinnervation after FCN transplantation or nerve-muscle pedicle implantation in the cricoarytenoideus dorsalis muscle.

    Full-thickness defects of the entire nasal ala, including the rim, can be challenging to reconstruct. A forehead flap may provide a more imperceptible and natural-appearing reconstructed nasal ala. Previously, many authors have insisted adding cartilaginous infrastructural support for an entire, full-thickness defect to keep the postoperative alar structure symmetrical. They finally use a forehead flap after thinning of the distal covering portion subcutaneously, possibly for a Caucasian-type nasal ala. However, Asian skin has a thicker and more compact dermis than that of Caucasian skin, and the Asian ala is rounder and thicker. There may be another approach for an Asian-type nasal ala. The authors propose the possibility of nasal alar reconstruction for an entire, full-thickness defect in Asians using a forehead flap without structural support. Six patients with entire full-thickness nasal alar defects treated with full-thickness forehead flaps above the periosteum without structural support were reviewed. Five patients demonstrated esthetically good to excellent outcomes in color, texture, and symmetry. Their nasal linings were reconstructed using mucoperiosteal flaps or mucosal grafts. One patient treated with a nasal lining using a local flap showed a fair result esthetically. Asians forehead above the periosteum has adequate thickness and supportability to reconstruct the entire full-thickness nasal ala in Asians. No cartilage support is necessary.

    Primary surgical correction of cleft-lip nose deformity is now well accepted. Despite various surgical techniques proposed, perfect nasal symmetry has not been persistently attained. The main reason is that the maxillary deficiency is frequently overlooked.This paper presents 62 cases of unilateral cleft lip repaired over the last 20 years by using the author's modification of the Millard primary lip nose repair. Each of these patients had a minimum follow-up of 1 year (range 1-12 years).The technique consists of raising a small subcutaneous alar base flap (SCAB) from the nasolabial region. The flap is turned over like a book page to add bulk to the deficient maxilla and to elevate the depressed ala. It also controls alar rotation and permits its permanent fixation to the anterior nasal spine.The results show that this modification has improved the alar contour and symmetry in patients undergoing primary cleft-lip nasal repair. There was minimal increase in the operating time and the final scar is similar to the original Millard technique.

    Hypothesis that loss of integrity of the membranes in the craniocervical junction might be the cause of neck pain in patients with whiplash-associated disorders (WADs) has been proposed. In recent years, with development of more detailed magnetic resonance imaging (MRI) techniques, morphologic changes of the ligaments and membranes in the craniocervical junction, especially alar and transverse ligaments have been discussed. A meta-analysis was performed to evaluate the relationship of MRI signal changes of alar and transverse ligaments and WADs. A systematic search of EMBASE, PUBMED, and Cochrane Library and references from eligible articles were conducted. Comparative studies reporting on evaluating the relationship between MRI high-signal changes of alar and transverse ligaments and WADs were regarded eligible. A pooled estimate of effect size was produced. Alar ligaments: Six studies (total n = 622) were included. MRI signal changes of alar ligaments did not appear to be related with WADs (P = 0.20, OR = 1.54, 95 % CI = 0.80-2.94). Heterogeneity was present (I (2) = 46 %, P = 0.10), which was eliminated upon sensitivity analysis bringing the OR to 1.27 (95 % CI = 0.87-1.86, I (2) = 0 %). Transverse ligaments: Four studies (total n = 489) were included. MRI signal changes of transverse ligament did not appear to be related with WADs (P = 0.51, OR = 1.44, 95 % CI = 0.49-4.21). Heterogeneity was present (I (2) = 77 %, P = 0.005), which was eliminated upon sensitivity analysis bringing the OR to 0.79 (95 % CI = 0.49-1.28, I (2) = 0 %). MRI signal changes of alar and transverse ligaments are not supposed to be caused by whiplash injury, and MRI examination of alar and transverse ligaments should not be used as the routine workup of patients with WADs.

    Full Text Available Agricultural sustainability has become a major concern in arid regions of China. In order to better understand the influence of continuous cropping on soil quality, six experimental fields were established in the Alar Oasis of Xinjiang, including uncultivated land (as a zero year treatment duration and five different continuous cropping years on cotton fields, with different cropping durations (5, 10, 15, 20 and 25 years, respectively. Thirteen soil indicators were selected including soil physicochemical properties, nutrient properties and enzymatic activities. The results show that duration of continuous cropping of cotton fields significantly influences a number of soil properties. Cultivation durations ranked according to soil quality indexes (SQI are as follows: 15 years (0.828 > 20 years (0.816 > 10 years (0.668> 5 years (0.548 > 25 years (0.377 > 0 years (0.205, and sustainable yield index (SYI are as follows: 10 years (0.830 > 15 years (0.777 > 20 years (0.667 > 5 years (0.586 > 25 years (0.159.

    The authors report on a novel method of intraoperative navigation with inertial measurement units (IMUs) for implantation of S-2 alar iliac (S2AI) screws in sacropelvic fixation of the human spine and its application in cadaveric specimens. Screw trajectories were planned on a multiplanar reconstruction of the preoperative CT scan. The pedicle finder and screwdriver were equipped with IMUs to guide the axial and sagittal tilt angles of the planned trajectory, and navigation software was developed. The entry points were chosen according to anatomical landmarks on the exposed spine. After referencing, the sagittal and axial orientation of the pedicle finder and screwdriver were wirelessly monitored on a computer screen and aligned with the preoperatively planned tilt angles to implant the S2AI screws. The technique was performed without any intraoperative imaging. Screw positions were analyzed on postoperative CT scans. Seventeen of 18 screws showed a good S2AI screw trajectory. Compared with the postoperatively measured tilt angles of the S2AI screws, the IMU readings on the screwdriver were within an axial plane deviation of 0° to 5° in 15 (83%) and 6° to 10° in 2 (11%) of the screws and within a sagittal plane deviation of 0° to 5° in 15 (83%) and 6° to 10° in 3 (17%) of the screws. IMU-based intraoperative navigation may facilitate accurate placement of S2AI screws.

    Post-traumatic changes of the alar ligaments have been proposed to be the cause of chronic pain in patients after whiplash injury of the cervical spine. In addition to an asymmetric dens position, widening of the atlantodental distance to more than 12 mm can be an indirect sign of an alar ligament rupture. CT is recommended for detection of a avulsion fracture of the occipital condyle. Isolated ruptures of the alar ligaments are best visualized on MRI. In patients with chronic impairments after whiplash injuries changes of the alar ligaments on MRI must be differentiated from normal variants in healthy individuals. (orig.) [German] Posttraumatische Veraenderungen der Ligg. alaria werden als ursaechlich fuer chronische Beschwerden bei Patienten mit Beschleunigungsverletzungen der Halswirbelsaeule angesehen. Eine asymmetrische Densposition sowie eine Erweiterung der anterioren atlantoaxialen Distanz auf ueber 12 mm koennen auf konventionellen Roentgenaufnahmen ein indirektes Zeichen fuer das Vorliegen einer Fluegelbandverletzung sein. Die Computertomographie ist die Methode der Wahl zum Nachweis einer kondylaeren Ausrissfraktur des Lig. alare. Isolierte akute Bandverletzungen der Ligg. alaria sind hingegen in der MRT direkt nachweisbar. Bei Patienten mit chronischen Beschwerden nach Beschleunigungsverletzungen der Halswirbelsaeule muessen allerdings morphologische Auffaelligkeiten der Ligg. alaria im MRT von Normvarianten abgegrenzt werden.

    The ala is a unique landmark of the nose disposing aesthetic and functional properties. The head and neck area is the main site of appearance of nonmelanoma skin cancer. One third of them are located in the nose with an alar preponderance compared with other nasal subunits. Correction of alar defects is a challenging reconstructive task. The keystone perforator island flap (KPIF) was introduced as an alternative in nasal reconstruction by senior authors. In the present case series, KPIFs' application is introduced into the alar subunit as an alternative, versatile, and reproducible reconstructive option, even for the novice plastic surgeon. From April 2014 to September 2015, patients presenting with partial thickness alar defects (≤1.5 cm) secondary to tumor extirpation sustained reconstruction with different types of KPIF. A total of 31 patients (mean age of 72 years) were treated with various types of KPIF. The mean diameter of the defect was 1.14 cm. The vast majority of reconstructions concerned a type IV KPIF (18/31 or 58.1%). Sometimes an upward alar retraction was noted. A minimal rim wedge excision was performed (≤0.3 mm) using counterbalancing correcting sutures. All flaps survived without any sign of venous congestion, whereas the rim healed uneventfully. The mean follow-up period was 6.5 months. KPIF was introduced as a single-stage alternative reconstructive option for partial thickness alar defects, completing author's experience with this flap into such a challenging and aesthetically critical anatomic area.

    Full Text Available “A smile is happiness you'll find right under your nose”– Tom Wilson. This quote holds true just for patients, not for surgeons. The correction of the nose always poses a challenge to the cosmetic surgeon. Deformities of the external and internal nose may be congenital or acquired and may be secondary to soft tissue and/or osseo-cartilaginous abnormalities, leading to aesthetic and/or functional consequences. Alar flare poses a common problem, sometimes alone and sometimes in conjunction with other external deformities. Alar base reduction is generally considered when the interalar distance exceeds the intercanthal distance. It has been well documented that this simple additional procedure brings about a substantial enhancement in the nose. Various techniques have been described and used in the past, each having their benefits and drawbacks, with the modified Weir wedge excision, Aufricht nasal sill excision, and Bernstein V-Y advancement being the common ones. We hereby describe a technique that is simple yet effective in achieving the desired results and at the same time aims at preventing relapse to obtain satisfactory long term results.

  1. Wnt signal specifies the intrathalamic limit and its organizer properties by regulating Shh induction in the alar plate.

    The structural complexity of the brain depends on precise molecular and cellular regulatory mechanisms orchestrated by regional morphogenetic organizers. The thalamic organizer is the zona limitans intrathalamica (ZLI), a transverse linear neuroepithelial domain in the alar plate of the diencephalon. Because of its production of Sonic hedgehog, ZLI acts as a morphogenetic signaling center. Shh is expressed early on in the prosencephalic basal plate and is then gradually activated dorsally within the ZLI. The anteroposterior positioning and the mechanism inducing Shh expression in ZLI cells are still partly unknown, being a subject of controversial interpretations. For instance, separate experimental results have suggested that juxtaposition of prechordal (rostral) and epichordal (caudal) neuroepithelium, anteroposterior encroachment of alar lunatic fringe (L-fng) expression, and/or basal Shh signaling is required for ZLI specification. Here we investigated a key role of Wnt signaling in the molecular regulation of ZLI positioning and Shh expression, using experimental embryology in ovo in the chick. Early Wnt expression in the ZLI regulates Gli3 and L-fng to generate a permissive territory in which Shh is progressively induced by planar signals of the basal plate.

    Background Recent new anatomical and histological features of craniocervical junction in dogs and cats were described providing evidence of differences between the carnivore species. No information on these structures in foxes exists. Results Two parts of the alar ligaments were found. A longer one aroused from dens of axis to the internal (medial) surface of the occipital condyles and was called apical part. A shorter part originated from the entire length of the lateral edge of the dens of axis and terminated on the internal wall of the vertebral foramen of atlas and thus was called the lateral part. The transverse ligament of the atlas was widened in the mid region, above the dens of axis, and thickened at enthesis. Periosteal fibrocartilage was detected in the transverse ligament of the atlas at the enthesis, and sesamoid fibrocartilage was present on periphery in the middle of the ligament. Conclusions The craniocervical junction in foxes differs in part from other carnivores such as dogs and cats but resembles that of mesaticephalic dogs. The sesamoid and periosteal fibrocartilage supports the transverse ligament of the atlas whereas the alar ligaments have no cartilage. PMID:23557095

    The craniocervical junction is a complex anatomic location that contains the occipital bone, atlas, axis, and important complex ligamentous structures. The stability of this region is ensured only with the help of ligaments. A 6-year-old boy was admitted to our clinic for neck pain. Computed tomography and magnetic resonance imaging revealed a lytic bone lesion involving the C2 vertebral body and pedicle without odontoid tip. The tumor was resected using an anterior retropharyngeal approach and a wide marginal resection method. The odontoid tip and alar ligaments were protected, and the costal autografts were located between the C1-odontoid tip and the C3 body. The costal graft was stabilized in the C3 body with a miniplate. Then, C1-C3 posterior fixation with fusion was performed. The craniocervical junction was not considered unstable because the occipital bone was not involved in the fusion. Histologic examination confirmed the diagnosis of eosinophilic granuloma. Fusion was detected on a 1-year postoperative cervical computed tomography scan. The occiput should not be involved in the fusion area when the alar ligaments are preserved during surgery for a C2 lesion. Copyright © 2016 Elsevier Inc. All rights reserved.

    Describe a modified technique to increase nostril cross-sectional area using rib and septal cartilage graft over alar nasal cartilages. A modified surgical technique was used to obtain, carve and insert cartilage grafts over alar nasal cartilages. This study used standardized pictures and measured 90 cadaveric nostril cross-sectional area using Autocad(®); 30 were taken before any procedure and 60 were taken after grafts over lateral crura (30 using costal cartilage and 30 using septal cartilage). Statistical analysis were assessed using a model for repeated measures and ANOVA (Analysis of Variance) for the variable "area". There's statistical evidence that rib cartilage graft is more effective than septal cartilage graft. The mean area after the insertion of septal cartilage graft is smaller than the mean area under rib graft treatment (no confidence interval for mean difference contains the zero value and all P-values are below the significance level of 5%). The technique presented is applicable to increase nostril cross section area in cadavers. This modified technique revealed to enhance more nostril cross section area with costal cartilage graft over lateral crura rather than by septal graft.

    A randomized controlled trial was designed to assess the effectiveness of two alar base cinch techniques on the changes in nasolabial morphology after bimaxillary orthognathic surgery. Sixty patients requiring a Le Fort I osteotomy to correct skeletal discrepancies were selected randomly to receive either conventional or modified alar base cinching during the intraoral wound closure procedure. Conventional cinching passed through nasalis muscle and anterior nasal spine. Modified cinching also passed through dermis tissue to increase the anchorage. Postoperative hard and soft tissue changes were evaluated using cone beam computed tomography and three-dimensional stereophotogrammetry at predefined time points. Forty-eight patients with a skeletal class III malocclusion were included. In the conventional group, there was an increase of 0.31 ± 1.31 mm in nasal width and an increase of 0.97 ± 1.60mm in columellar length. In the modified group, there was an increase of 0.81 ± 1.87 mm in the cutaneous height of the upper lip and a decrease of 0.76 ± 1.56 mm in lower prolabial width. Patients with an initial narrow nasal width, alar base width, and less vertical nostril show were more susceptible to a greater degree of change after surgery. Both alar base suture techniques are effective at controlling nasolabial form changes resulting from class III dual-jaw orthognathic surgery.

    Surgical reposition of the maxilla by means of a Le Fort I osteotomy is a, widely used, procedure to correct dentofacial deformities. Maxillary intrusion, especially, is known to cause unwanted side effects on the orofacial soft tissues, such as broadening of the alar base, loss of vermilion show of

    Our aim was to characterise and classify structural changes in the alar ligaments in the late stage of whiplash injuries by use of a new MRI protocol, and to evaluate the reliability and the validity of this classification. We studied 92 whiplash-injured and 30 uninjured individuals who underwent proton density-weighted MRI of the craniovertebral junction in three orthogonal planes. Changes in the alar ligaments (grades 0-3) based on the ratio between the high signal area and the total cross-sectional area were rated twice at a 4-month interval, independently by three radiologists. Inter- and intraobserver statistics were calculated by ordinary and weighted kappa. Cases classified differently were reviewed to identify potential causes for disagreement. The alar ligaments were satisfactorily demonstrated in all cases (244 ligaments in 122 individuals). The lesions, 2-9 years after the injury, varied from small high-signal spots to high signal throughout the cross-sectional area. Signal was highest near the condylar insertion in 82 of 94 ligaments, indicating a lesion near that insertion, and near the dental insertion in eight, indicating a medial lesion. No grade 2 or 3 lesion was found in the control group. At least two observers assigned the same grade to 214 ligaments (87.7%) on the second occasion. In 30 ligaments (12.3%) this agreement was not obtained. Pair-wise interobserver agreement (weighted kappa) was fair to moderate (0.31-0.54) in the first grading, improving to moderate (0.49-0.57) in the second. Intraobserver agreement (weighted kappa) was moderate to good (0.43-0.70). Whiplash trauma can cause permanent damage to the alar ligaments, which can be shown by high-resolution proton density-weighted MRI. Reliability of classification of alar ligament lesions needs to be improved. (orig.)

    Achieving fusion across the lumbosacral junction is challenging because of the unfavorable biomechanics associated with ending a fusion at this level. Bicortical placement of S1 pedicle screws can increase the construct stability at the lumbosacral junction; however, construct failure and pseudoarthrosis can still result. Iliac screws have been shown to increase the stiffness of lumbosacral constructs, but disadvantages include difficulty in connecting the iliac screw to adjacent sacral screws, painful screw loosening or prominence requiring removal, and the inability to place the screws in some patients with previous iliac crest autograft harvest. The purpose of the study is to describe a technique of S2 alar screw placement using three-dimensional image guidance. The study design is a retrospective analysis. Twenty patients undergoing lumbosacral fusion had 32 screws placed using this technique. An independent radiologist graded screw placement and lumbosacral fusion on thin-cut postoperative computed tomographic (CT) scans. Image guidance in this study was accomplished with the Medtronic Stealth Station Treon (Medtronic Inc., Littleton, MA, USA) used in conjunction with the O-ARM (Medtronic Inc.). Indications for placement of S2 alar screws included the following: to adjunct S1 pedicle screws in multilevel fusion cases; as an adjunct or alternative to S1 pedicle screws in pseudoarthrosis revision cases in which the S1 screws had loosened; as an alternative to S1 pedicle screws in cases where medial trajectory of an S1 pedicle screw was difficult to obtain because of a low-set lumbosacral junction; and a combination of the above. The entry point of the screw was typically chosen lateral and superior to the S2 dorsal foramen with the trajectory directed anterior, inferior, and lateral. Attempt was made to place the screw with the tip purchasing, but not penetrating through, the triangular area of cortical bone that can be found at the anterior, inferior, and

    The 2Π(4p)-X2Π(3p) band system of AlAr has been observed using two-photon excitation. The spectrum consists of a short progression of doublet bands, with spin-orbit intervals that are close to that of Al(4p). Potential energy curve fitting yielded a bond dissociation energy for 2Π(4p) of De = 495(5) cm-1 and an approximate bond length of Re = 3.33(4) Å.

    Degenerative changes in the upper cervical spine may be age related degeneration or a pathological process such as rheumatoid arthritis. However, to our knowledge, the relationship between the apical and alar ligaments and these anomalies has not been discussed. We present anatomical variations of the anterior atlanto-dental joint observed during cadaveric dissection of adult craniovertebral junctions, the relationship with the alar and apical ligaments and discuss possible origins and clinical implications. The upper cervical spine including part of the occiput was dissected from cadavers whose mean age at death was 78.9 years-old. The anterior atlanto-dental joint and apical and alar ligaments were observed and any atypical findings were noted. In eleven specimens, seven had a dens corona, three had an os odontoideum and one had a dens aureola, which arose from the upper part of the anterior arch of the atlas. Only four specimens had an apical ligament. The possible etiologies and the clinical applications of these craniovertebral anomalies in a geriatric population should be appreciated by the clinician treating patients with disease in this area or interpreting imaging in the region.

    The aim of this study was to assess the effectiveness of the nasal alar base cinch suture following Le Fort I osteotomy at long-term follow-up. One hundred and forty participants (89 female, 51 male) aged between 16 and 51 years underwent Le Fort I osteotomy with submental intubation. Anthropometric measurements of the nose were taken intraoperatively, immediately postoperative, and for up to 3 years postoperative: the maximum lateral convexity of the alae (Al-Al) and the lateral extremity of the alar base curvature at the alar groove (Ac-Ac). The use of a cinch suture was recorded. The results were analysed using a linear mixed-effects model analysis. One hundred and six participants had cinch sutures and 34 had no cinch sutures. Following Le Fort I osteotomy, there were significant increases in Ac-Ac (by 4.29mm) and Al-Al (by 3.70mm) (both PAlar width remained stable over 3 years, with an increase of 0.36mm for Al-Al (P>0.05) and 1.03mm for Ac-Ac (Palar base width changes, which were found to be relatively stable at 3 years.

    Objective : This study aimed to analyze the asymmetry of the pyriform aperture and alar base in patients with unilateral secondary nasal deformities by three-dimensional computed tomography (3D-CT). Methods : 3D-CT images of the subject group of 101 adult patients and of a control group of 65 normal adults were examined. Sixty-nine patients without alveolar bone grafting (ABG) were classified as Group A, and 32 patients with ABG were classified as Group B. Seven landmarks (INM, LPA, IPA, Gbase, Gsup, Glat, and Sbal) were measured for both the subject and control groups, and comparative analyses were done to assess the degree of asymmetry in the subject group. Results : For over 95% of Group A and 80% to 85% of Group B, the index of LPA and IPA showed asymmetry or marked asymmetry. The index of Gbase, Glat, Gsup, and Sbal showed symmetry for around 50% of Group A and about 60% of Group B. In Group A, dorsal, lateral, and caudal translocation was found on the cleft side in LPA and IPA, while all soft landmarks showed dorsal translocation. In Group B, caudal translocation was found in both LPA and IPA, but only LPA appeared dorsal on the cleft side, while Glat showed dorsal and caudal translocation. Conclusion : The results indicated that the degree of asymmetry of hard tissue landmarks far exceeded that of the soft tissue landmarks, and the degree of asymmetry of pyriform aperture was higher than expected for patients after ABG.

    Spondylodiscitis still remains a serious problem, especially in immunocompromised patients. Surgery is necessary when nonsurgical treatment is unsuccessful. Although minimally invasive spine stabilization (MISt) with percutaneous pedicle screws is less invasive, percutaneous sacropelvic fixation techniques are not common practice. Here, we describe 2 cases in which spondylodiscitis in the lumbosacral spine was treated with percutaneous stabilization using an S2 alar-iliac (S2AI) screw technique. Case 1 is a 77-year-old man who presented with low back pain and high fever. He was diagnosed with spondylodiscitis at L4-5. He had a history of lung cancer, which was complicated by the recurrence. Because nonsurgical treatment failed, MISt with percutaneous S2AI screws was performed. The patient's low back pain subsided markedly 1 week after surgery, and there was no screw/rod breakage or recurrence of infection during the follow-up period. Case 2 is a 71-year-old man who presented with hemiparesis because of a stroke. He also developed high fever and was diagnosed with spondylodiscitis at L5-S1. Because nonsurgical treatment failed, the patient was treated by MISt with percutaneous S2AI screws while being maintained on anticoagulants for stroke. Although his clinical symptoms had markedly improved, a postoperative lumbar computed tomography scan demonstrated a bone defect at L5-S1. An anterior spinal fusion with an iliac bone graft at L5-S1 was performed when a temporary cessation of anticoagulants was permitted. Both patients tolerated the procedures well and had no major perioperative complications. MISt with percutaneous S2AI screws was less invasive and efficacious for lumbosacral spondylodiscitis in providing rigid percutaneous sacropelvic fixation. Copyright © 2016 Elsevier Inc.

    Classic cinch suture narrowing of the nasal alar base by medially suturing the bilateral nasolabial soft tissue with one long suture has a limited effect. The modified cinch method described in the present study anchors non-absorbable sutures to the bilateral lower border of the piriform rim and provides optimal direction, position, and stability. The sutures can be shortened and the strength kept stable while the surgical wounds heal. Separate bilateral sutures can also reduce interference and distortion from nasotracheal intubation and make the nasolabial profile more symmetrical. Seventeen consecutive cases of maxillary Le Fort I osteotomy were analyzed. The nasal and alar base width changes were 0.4±1.2mm and 0.1±1.1mm, respectively, and the widening rate was only 1.1%. Compared with the results of other studies, postoperative nasal flaring was well controlled using the modified cinch suture anchored to the bilateral lower border of the piriform rim described in this study.

    2016-01-01

    Full Text Available Background: Surgical treatments for adult spinal deformities often include pelvic fixation, and the feasibility of sacral-2 alar iliac (S2AI screw fixation has been shown previously. However, sometimes S2AI screw fixation cannot be applied due to the presence of an osteolytic lesion or trauma or because the biomechanical properties of only an S2AI screw is insufficient. Therefore, we questioned the feasibility of using sacral AI screws in other segments and determined whether S3AI and S4AI screws have the potential to be used for sacral fractures. The aim of this study was to investigate the feasibility and radiological features of sacral AI fixation in S1–S4 in an adult population using 3D imaging techniques. Methods: Computed tomography (CT scans were taken of 45 patients and were imported into Mimics (Version 10.01, Materialise, Belgium software to reconstruct the 3D digital images. Next, a cylinder (radius of 3.5 mm was drawn to imitate the screw trajectory of a S1–4 AI screw, and every imitated screw in each segment was adjusted to a maximum upward and downward angle to acquire the feasible region. The parameters of the S1–4AI screw trajectories were measured. Results: Sacral AI screws could be successfully imitated using 3D digital imaging. The S4AI screw trajectory could be obtained in 19 of 45 patient images (42.2%, while the feasibility rates of S1AI, S2AI, and S3AI screw fixation were 100%, 100%, and 91.1% (41/45, respectively. The feasible regions of S1AI, S2AI, and S3AI screw trajectories were wide enough, while the adjustable angle of S4AI screws was very small. Conclusion: It is feasible to place S1–2AI screws in the entire adult population and S3–4AI screws in some of the adult population. Furthermore, our study suggested that 3D digital images are suitable to study the feasibility of new screw fixation.

    Rotationally resolved spectra were recorded for six bands of the AlAr B 2Σ+←X 2Π1/2 transition. Vibrational and rotational constants derived from these spectra were used to determine the upper and lower state potential energy curves. The accuracy of these potentials was assessed through calculations of the spectroscopic constants and Franck-Condon factors. Dissociation energies of D'e=440+35-8 cm-1 and D'e=180+40-10 cm-1 were obtained for the B and X states, respectively. The interaction between X 2Π1/2 and the low-lying A 2Σ+ state has been characterized by analysis of the ground-state lambda doublet splitting.

  12. Calcification of the Alar Ligament Mimics Fracture of the Craniovertebral Junction (CVJ): An Incidental Finding from Computerised Tomography of the Cervical Spine Following Trauma

    Che Mohamed, Siti Kamariah; Abd. Aziz, Azian

    2009-01-01

    When performing a radiological assessment for a trauma case with associated head injury, a fragment of dense tissue detected near the craniovertebral junction would rapidly be assessed as a fractured bone fragment. However, if further imaging and evaluation of the cervical spine with computerised tomography (CT) did not demonstrate an obvious fracture, then the possibility of ligament calcification would be considered. We present a case involving a previously healthy 44-yearold man who was admitted following a severe head injury from a road traffic accident. CT scans of the head showed multiple intracranial haemorrhages, while scans of the cervical spine revealed a small, well-defined, ovoid calcification in the right alar ligament. This was initially thought to be a fracture fragment. Although such calcification is uncommon, accident and emergency physicians and radiologists may find this useful as a differential diagnosis in patients presenting with neck pain or traumatic head injury.

METHODS: A modified surgical technique was used to obtain, carve and insert cartilage grafts over alar nasal cartilages. This study used standardized pictures and measured 90 cadaveric nostril cross-sectional area using Autocad®; 30 were taken before any procedure and 60 were taken after grafts over lateral crura (30 using costal cartilage and 30 using septal cartilage. Statistical analysis were assessed using a model for repeated measures and ANOVA (Analysis of Variance for the variable "area". RESULTS: There's statistical evidence that rib cartilage graft is more effective than septal cartilage graft. The mean area after the insertion of septal cartilage graft is smaller than the mean area under rib graft treatment (no confidence interval for mean difference contains the zero value and all P-values are below the significance level of 5%. CONCLUSIONS: The technique presented is applicable to increase nostril cross section area in cadavers. This modified technique revealed to enhance more nostril cross section area with costal cartilage graft over lateral crura rather than by septal graft.OBJETIVO: Descrever uma técnica modificada para se aumentar a área seccional externa da narina com cartilagem septal e costal acima das cartilagens alares nasais.

    Conventionally, articles dealing with nasal defects plan reconstructions regarding the aesthetic subunits, imposing their systematic respect. We propose to study the reconstruction of a crossroad region of three subunits, tip, alar lobule and lateral sidewall, where that full compliance is not possible, in our experience of 36 patients. Our retrospective study from January 2011 to December 2012 focused on patients with a defect in this crossroad region that was repaired by skin graft or flap. We described the population of the study, histological type of the lesions, surgical procedures and complications. We evaluated the reconstructions performed with a photographic review 1 year post-surgery according to the criteria of symmetry, discoloration, thickness, shrinkage, and rating on the Vancouver Scar Scale, which helped create an overall aesthetic score for the reconstruction. Of 144 patients with a nasal defect, 36 of them (25%) were included, presenting a defect in our study area. The reconstruction was made by eight hatchet flaps, eight frontal flaps, seven bilobed flaps, five advanced-rotated lateronasal flaps, four nasolabial flaps, two Rybka flaps and two total skin grafts. The advanced-rotated flap, hatchet flap and bilobed flap had the highest results and scores, according to the criteria assessed. Rybka flap and total skin grafts had the lowest results. The occurrence of a defect in the crossroads seems common. In this indication, specific local flaps had a favourable outcome, including review of the overall esthetic score which was created to standardize the assessment of reconstructions.

    A rigid spino-pelvic fixation to anchor long constructs is crucial to maintain the stability of long fusion in spinal deformity surgery. Besides obtaining immediate stability and proper biomechanical strength of constructs, the S2 alar-iliac (S2AI) screws have some more advantages. Four Korean fresh-frozen human cadavers were procured. Free hand S2AI screw placement is performed using anatomic landmarks. The starting point of the S2AI screw is located at the midpoint between the S1 and S2 foramen and 2 mm medial to the lateral sacral crest. Gearshift was advanced from the desired starting point toward the sacro-iliac joint directing approximately 20° angulation caudally in sagittal plane and 30° angulation horizontally in the coronal plane connecting the posterior superior iliac spine (PSIS). We made a S2AI screw trajectory through the cancellous channel using the gearshift. We measured caudal angle in the sagittal plane and horizontal angle in the coronal plane. A total of eight S2AI screws were inserted in four cadavers. All screws inserted into the iliac crest were evaluated by C-arm and naked eye examination by two spine surgeons. Among 8 S2AI screws, all screws were accurately placed (100%). The average caudal angle in the sagittal plane was 17.3±5.4°. The average horizontal angle in the coronal plane connecting the PSIS was 32.0±1.8°. The placement of S2AI screws using the free hand technique without any radiographic guidance appears to an acceptable method of insertion without more radiation or time consuming. PMID:26819698

The functional groups (2 and (3 exploit similar habitats but with different life styles, the molossids foraging in open areas at fast flight speed and the vespertilionids foraging in more wooded areas with maneuverable and slow flight. Desmodus rotundus clearly constitute a single group that may be related to flights from a far communal roost and their particular mode of locomotionComparamos la morfología alar de ocho quirópteros chilenos, incluyendo dos especies previamente estudiadas. Correlacionamos los hallazgos con la información ecológica disponible.

Los murciélagos de cola libre, T. brasiliensis, M.kalinowskii y D. rotundus, sin uropatagio, mostraron una baja superficie alar, pero mientras los molósidos mostraron alta razón de aspecto, la de D. rotundus fue sólo moderada. Desmodus rotundus mostró la menor envergadura alar, relativa a su masa, y la mayor carga alar. El segundo momento del área del húmero de M. chiloensis es menor que lo esperado a partir de las predicciones alométricas, sugiriendo una pobre resistencia a la fuerzas de flexión y a la torsión. Todos los demás vespertiliónidos mostraron un alto segundo momento del área, lo que puede ser explicado por su energéticamente costosa forma de locomoción, especialmente en especias con alta potencia parásita a consecuencia de sus largas orejas. El alto Ih que mostró D. rotundus puede ser explicado por su moderada razón de aspecto y por su elevada masa corporal que incrementa el torque producido por el peso. El análisis de

    Background One of the most confusing and difficult aspects of complete denture prosthodontics is the selection of appropriately sized maxillary anterior denture teeth. Various guidelines have been suggested for determining the size of anterior teeth, but different opinions have been reported regarding their significance. In the study reported here, the relationships between facial measurements and the width of maxillary anterior teeth in two ethnic groups, namely Aryans and Mongoloids, were determined. Objective The aims of the study were to determine the inner inter-canthal distance (ICAD), inter-pupillary distance (IPD), inter-commissural width (ICOW), inter-alar width (IAW), and the combined width of maxillary anterior teeth (CW) in Aryans and Mongoloids and to determine the relationships between these measurements. Materials and methods Impressions of the teeth of 170 dentulous subjects (85 males and 85 females) were made with alginate then Type IV gypsum product was poured in. Measurements of the cast maxillary anterior teeth at their widest dimension (contact areas) were made with the Boley gauge. ICAD, IPD, ICOW, and IAW distances were also measured with a Boley gauge. Results For all 170 subjects, 85 Aryans and 85 Mongoloids, Pearson’s correlation coefficient (r) for IAW, IPD, ICOW, ICAD, and CW was calculated. In Aryans, highly significant (P<0.001) but weak correlations were found between CW and IAW, IPD, and ICOW. In Mongoloids, a highly significant (P<0.001) and weak correlation was found only between CW and IPD. Conclusion Within the limitations of this study, the results suggest that the IAW, IPD, and ICOW for Aryans and IPD for Mongoloids can be used as a preliminary method for determining the width of the maxillary anterior teeth in edentulous patients.

    南疆城市阿拉尔市区的沥青混凝土道路每年冬-春就会出现不同程度的变形破坏现象,通过对虹桥路试验路段不同深度路基结构层及一侧绿化带内相应深度取土样,运用SEM微观电镜观测土样微观结构发现:路基水泥土稳定层膨胀疏松,掺杂着大量具有膨胀作用的硫酸钠晶体和硫酸钙晶体,而其他结构层很少,绿化带土样则几乎观测不到,表明水泥土稳定层发生膨胀是导致沥青混凝土道路变形破坏的主要因素。对路基内盐分及温度、路面竖向变形、地下水位变化分析得知,路基内盐-温-水共同作用是促使水稳层产生膨胀变形的因素,因此对于该地区道路工程应做好控温限盐防水的措施。%There are different degrees of deformation on the urban road asphalt concrete every winter and spring in Alar, a city in southern Xinjiang. Soil samples are taken from different depth of subgrade structure layers and one side of the green belt in Hongqiao Road test section. Its micro structure with SEM scanning display that subgrade soil cement stabi⁃lized layer is expanded and loose, mixed with a large number of expanded elements such as sodium sulfate and calcium sulfate crystal, which are few in other layers, and almost none in green belt. The results show that the expansion of soil ce⁃ment stabilized layer is the main factor of asphalt concrete pavement deformation. Analysis of the salt, temperature, verti⁃cal deformation in subgrade pavement and changes of underground water level prove that the interaction of salt-tempera⁃ture-water in subgrade promotes the expansion of the water layer, so it is better to control the temperature and salt, and take water proofing measures for road engineering in this area.

Nuestros resultados muestran que T. brasiliensis es un murciélago más robusto, de mayor envergadura, pero con un área alar similar a la de M. chiloensis. Esta última especie tiene una menor variabilidad en su masa y área cortical del húmero, que probablemente se encuentre relacionada con restricciones mecánicas y energéticas impuestas por su diseño. Descontando el efecto de la masa se detectaron diferencias en el diámetro externo y diámetro medular del húmero con una similar área cortical. El húmero de T. brasiliensis es un hueso de similar longitud, más ancho y con un menor grosor cortical que el de M. chiloensis, lo que está relacionado con una mayor resistencia a las fuerzas de flexión y torsión.

    Full Text Available Recently, the genetic basis and developmental mechanisms underlying the process of melanization have become progressively elucidated, allowing us to study the evolutionary processes that govern the huge variability of pigmentation observed in nature. However, environmental factors contributing to such variability have received little attention, even though they might have profound ecological consequences. Here we describe a method for analyzing the wing melanization patterns of drosophilids in both qualitative and quantitative ways. We test this method on wings of Drosophila buzzatii Patterson & Wheeler individuals, reared in control and alkaloid-enriched mediums. The alkaloids were extracted from the secondary host of these flies, Echinopsis terscheckii (Parm. ex Pfeiff. Friedrich & Rowley, and their effect on wing pigmentation is analyzed, bearing in mind the adverse effects that these compounds have on the development of D. buzzatii. Alkaloid-reared flies were shown to attain a higher degree of wing melanization, accompanied with differences in the spatial distribution of the pigment. Modifications at both metabolic and gene regulatory levels are proposed to explain the changes that chemical stressful conditions are shown to induce in this character. We propose the utilization of this procedure in studies of environmental dependence of pigmentation.Recientemente, hemos avanzado en nuestra comprensión de las bases genéticas y los mecanismos subyacentes al proceso de melanización durante el desarrollo, lo que permite el estudio de los procesos evolutivos que gobiernan la variabilidad de pigmentación presente en la naturaleza. Sin embargo, los factores ambientales que contribuyen a dicha variabilidad han recibido poca atención, aún cuando pueden conllevar profundas consecuencias a nivel ecológico. En este trabajo, presentamos un método para analizar los patrones de melanización alar de drosofílidos, de forma cualitativa y cuantitativa

    2014-01-01

    Full Text Available The purpose of this study is to evaluate the surgical outcome after using composite grafts for secondary cleft lip nasal deformities. A retrospective cohort study of one surgeon’s outcome of 35 consecutive performed secondary cleft lip nasal deformity repair. Thirty-five patients with secondary nose deformity related to unsatisfactory cleft lip repair were operated using the proposed surgical technique since 2008. All these patients met the study criterion of having anthropometric measurements performed at least one year postoperatively. Measurement of nostril size was performed at the right and left side of the nose, preoperatively and at least one year postoperatively. The study found statistically significant differences between the preoperatory and postoperatory nose measurements. In addition, we have not found statistically significant differences between the cleft and noncleft nostril sizes measured at least one year postoperatively. The findings suggest that the proposed technique is a good alternative to address secondary nose deformity related to cleft lip primary repair.

    1989-05-01

    Interatomic potential parameters for the ground X1,2 2Π1/2,3/2 and excited B 2Σ+1/2 states of jet-cooled van der Waals complexes of Al atoms with rare gases have been determined from fluorescence excitation and emission spectra. Vibrational numbering in the B states is established from isotopic and rotational broadening of fluorescence excitation line shapes. Bond distances are estimated by comparison with analogous states of alkali-rare gas molecules, and by modeling observed relative emission intensities with calculated Franck-Condon factors. Morse potentials are found to adequately describe the data for the ground states, but for the excited states there are indications of departures from Morse functions at large internuclear distances. Dissociation energies De are estimated from Birge-Sponer extrapolations. Multiplet splittings in Al-rare gas complexes are compared to those in In-rare gas complexes and are discussed in terms of an empirical treatment of spin-orbit coupling, which assumes that the spin-orbit coupling constant for the molecule is the same as that for the atom. The ground X1 state of each Al-rare gas molecule is more stable than that of the analogous In complex, whereas the spin-orbit excited X2 state is less stable. This is explained by the greater mixing between the X1 state and the dissociative A 2Σ+1/2 state for indium over aluminum, caused by the greater spin-orbit coupling constant for the heavier metal.

  15. Correlation consistent basis sets for molecular core-valence effects with explicitly correlated wave functions: The atoms B-Ne and Al-Ar

    Correlation consistent basis sets have been optimized for accurately describing core-core and core-valence correlation effects with explicitly correlated F12 methods. The new sets, denoted cc-pCVnZ-F12 (n =D, T, Q) and aug-cc-pCF12VnZ (n =D, T, Q, 5), were developed by augmenting the cc-pVnZ-F12 and aug-cc-pVnZ families of basis sets with additional functions whose exponents were optimized based on the difference between all-electron and valence-electron correlation energies. The number of augmented functions added is fewer, in general, than in the standard cc-pCVnZ and cc-pwCVnZ families of basis sets. Optimal values of the geminal Slater exponent for use with these basis sets in MP2-F12 calculations are presented and are also recommended for CCSD-F12b calculations. Auxiliary basis sets for use in the resolution of the identity approximation in explicitly correlated calculations have also been optimized and matched to the new cc-pCVnZ-F12 series of orbital basis sets. The cc-pCVnZ-F12 basis sets, along with the new auxiliary sets, were benchmarked in CCSD(T)-F12b calculations of spectroscopic properties on a series of homo- and heteronuclear first and second row diatomic molecules. Comparing the effects of correlating the outer core electrons in these molecules with those from conventional CCSD(T) at the complete basis set limit, which involved calculations with new cc-pCV6Z basis sets for the second row elements that were also developed in the course of this work, it is observed that the F12 values are reasonably well converged already at just the triple-ζ level.

    Full Text Available La modificación de perfiles aerodinámicos para generar bordes de salida con espesor ha probado que es posible obtener buen rendimiento aerodinámico sin comprometer los requerimientos estructurales. Dos diferentes métodos son analizados: el método de recorte y el método de adición de espesor. Simulaciones bidimensionales fueron realizadas usando Ansys CFX® para valores del número de Reynolds de 3.2 millones. Se presenta un estudio basado en los métodos de Taguchi de la familia de perfiles NACA de cuatro dígitos bajo distintos métodos de modificación. Finalmente, un estudio detallado de la modificación del perfil NACA 4421 para distintos espesores de borde de salida es presentado. Los resultados obtenidos muestran que el aumento del coeficiente máximo de sustentación, del ángulo crítico de ataque y del coeficiente de arrastre es común a todos los métodos de modificación, mientras que se probó que en el método de recorte se produce una disminución de la curva de coeficiente de sustentación debida a las alteraciones geométricas causadas. En general, el método de adición de espesor produce perfiles con mayores aumentos en el coeficiente máximo de sustentación y en el ángulo crítico de ataque. / Blunt trailing edge airfoil modification methods have shown that a compromise between aerodynamic performance and structural benefits can be achieved. Two modification methods are studied: the cutting off method and the added thickness method. Two-dimensional simulations were obtained in Ansys CFX® for a typical Reynolds number of 3.2 million. A Taguchi Method experiment is conducted for the study of the four-digit NACA airfoil family with the proposed modification methods. A detailed study for the NACA 4421 modified with several trailing edge thickness values was completed. The results obtained show that the increase in the maximum lift coefficient, the delayed stall and the drag coefficient increase are common to all modification methods studied, whereas it is proven that for the cutting off method the lift coefficient curve displacement to higher angles of attack is caused by the loss of camber. Finally, it was proved that the added thickness method produces larger maximum lift coefficients and larger critical angles of attack than the cutting off method.

    Aim:The authors observed the nostril lfoor in a gross cadaver specimen histologically and innovated a medially based de-epithelialized lfap for nasal base narrowing and nostril sill augmentation. Methods:In cadaver, fully thick section was taken from the nostril sill at the midpoint of the columella base and ala base, and stained with Masson-Trichrome. In eight patients, circumferential incision along the nostril sill and alar base freed the alar base from the upper lip. At the columellar base, fresh epithelium was shaved on the medial side of the incision line. The widened scar on the upper lip was excised. The de-epithelialized tip of the columellar base was pulled under the medial tip of the alar base lfap and sutured tightly. Four anthropometric distances were measured preoperatively and postoperatively. Results:Histologically the nostril sill was composed of thickened dermis. Just below the dermis, the depressor septi nasi muscle ran obliquely, augmenting the nostril sill. The nostril lfoor width, alar distance, and alar curvature distance decreased on the cleft side after the operation. Conclusion:A medially based de-epithelialized lfap narrows the alar base and augments the nostril sill simultaneously, since the de-epithelialized part of the excess skin augments the depressed nostril sill.

  14. Changes in light- and nitrogen-use and in aboveground biomass allocation patterns along productivity gradients in grasslands.

    Light- and nitrogen-use change was examined along productivity gradients in natural grasslands at Laelatu, western Estonia, both at community level and in most abundant species. Aboveground biomass (M) ranged from 341 to 503 g m(-2) in wet (W) and from 248 to 682 g m(-2) in dry (D) community. Aboveground leaf area ratio (aLAR) decreased with rising M in D site, while it increased in W site. In a high-aLAR W community (significantly higher compared to D), adjustment of leaf morphology through an increase in specific leaf area is responsible for an increase in aLAR with rising productivity. In low-aLAR stand, by contrast, adjustment of biomass allocation due to decrease in aboveground leaf mass fraction is primarily responsible for the tendency of aLAR to decline. In conclusion, a decrease in aLAR is not a universal response to increasing M. We hypothesise that there exists an optimum of light acquisition efficiency (ΦM) along a productivity gradient independent of community type. Aboveground nitrogen-use efficiency (aNUE) decreased in high-aLAR, W community with increasing M, while in low-aLAR, D site, there was no relationship along a gradient, although aNUE increased along six plots dominated by graminoids. A trade-off was established between leaf nitrogen content per unit leaf area (N A) and aLAR.

    There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities. In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties. The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions. Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position. With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary. 4 Therapeutic. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Nasolabial cyst is an uncommon nonodontogenic, developmental cyst, originating in maxillofacial soft tissues characterised by its extraosseous location in nasal alar region. This cyst is frequently asymptomatic with most usual sign being alar nose elevation. Its frequency is around 0.7% of cysts of the jaws and 2.5% of the nonodontogenic cyst. A case report of a nasolabial cyst for which a radiographic contrast medium was used in order to localise the lesion is discussed. This article documents the presentation and management of nasolabial cyst in a 50-year-old woman and discusses the considerations related to the diagnosis.

  12. Urea Unfolding Study of E. coli Alanyl-tRNA Synthetase and Its Monomeric Variants Proves the Role of C-Terminal Domain in Stability

    Directory of Open Access Journals (Sweden)

    Baisakhi Banerjee

    2015-01-01

    Full Text Available E. coli alanyl-tRNA exists as a dimer in its native form and the C-terminal coiled-coil part plays an important role in the dimerization process. The truncated N-terminal containing the first 700 amino acids (1–700 forms a monomeric variant possessing similar aminoacylation activity like wild type. A point mutation in the C-terminal domain (G674D also produces a monomeric variant with a fivefold reduced aminoacylation activity compared to the wild type enzyme. Urea induced denaturation of these monomeric mutants along with another alaRS variant (N461 alaRS was studied together with the full-length enzyme using various spectroscopic techniques such as intrinsic tryptophan fluorescence, 1-anilino-8-naphthalene-sulfonic acid binding, near- and far-UV circular dichroism, and analytical ultracentrifugation. Aminoacylation activity assay after refolding from denatured state revealed that the monomeric mutants studied here were unable to regain their activity, whereas the dimeric full-length alaRS gets back similar activity as the native enzyme. This study indicates that dimerization is one of the key regulatory factors that is important in the proper folding and stability of E. coli alaRS.

  13. Functional considerations in revision rhinoplasty.

    Science.gov (United States)

    Ballert, John A; Park, Stephen S

    2008-08-01

    The development of nasal obstruction after rhinoplasty is associated with significant patient dissatisfaction. Correction of nasal obstruction requires a thorough evaluation to determine the ANATOMIC EPICENTER of obstruction. The offending structure can usually be traced to abnormalities in the internal nasal valve, intervalve area, or the external nasal valve and may be static or dynamic. Surgical correction of the internal nasal valve using spreader grafts, flaring sutures, and butterfly grafts has been shown to increase the cross-sectional area of this nasal valve, improving nasal airflow and patient satisfaction. External valve dysfunction from cicatricial stenosis may be addressed with local flaps; however, larger stenoses may require composite grafts. Alar base malposition can be addressed by repositioning of the alar base with local island flaps. Intervalve dysfunction involves the important area between the external and internal valves, under the supra-alar crease, and is the most common site of obstruction. Its correction often involves alar batten grafts and reconstruction of the lateral crura. Inferior turbinate hypertrophy and concha bullosa may be addressed as adjunctive therapy to increase nasal airflow. This article on nasal obstruction after rhinoplasty emphasizes the precise anatomic diagnosis and describes successful methods used to correct the dysfunction.

    We present a case of traumatic vertical atlantoaxial dislocation of 16 millimetres with a fatal outcome.

    1987-04-01

    Twelve specimens of the upper cervical spine were functionally examined by using radiography, cineradiography and computerized tomographic (CT) scan. The range of rotation was measured from CT images after maximal rotations to both sides. The left alar ligament was then cut and the examination repeated. The alar and transverse ligaments could be differentiated on CT images in axial, sagittal, and coronal views. Rotation at occiput-atlas was 4.35 degrees to the right and 5.9 degrees to the left and at atlas-axis it was 31.4 degrees to the right and 33 degrees to the left. After one-sided lesion of the alar ligament, there was an overall increase of 10.8 degrees or 30% of original rotation to the opposite side, divided about equally between the occiput-atlas and the atlas-axis. It is concluded that a lesion (irreversible overstretching or rupture of alar ligaments) can result in rotatory hypermobility or instability of the upper cervical spine.

  18. Atlantoaxial rotatory dislocation. A case report.

    1998-07-01

    Report of a child who sustained an acute atlantoaxial rotatory dislocation, associated with fractures of the clavicle and the temporal bone, and rupture of the alar ligament demonstrated by magnetic resonance imaging. To describe the radiographic and pathoanatomic characteristics of the injury process. Only five cases of traumatic atlantoaxial rotatory dislocation associated with fracture of the clavicle have been reported previously. This is the first report of a ruptured alar ligament demonstrated on magnetic resonance imaging in a patient with atlantoaxial rotatory dislocation associated with fractures of the clavicle and the temporal bone. Computed tomography revealed the Type 1 rotatory dislocation described by Fielding and Hawkins, and magnetic resonance imaging delineated the ruptured alar ligament. Traction in a halter, followed by 6 weeks of immobilization with a cervical collar, was successful in the management of the injury. Concomitant fractures of the right temporal bone and the right clavicle may yield excessive left rotation of the atlas on the axis, resulting in the rupture of the right alar ligament. Awareness of this condition allows early diagnosis and effective conservative treatment.

    Achieving solid osseous fusion across the lumbosacral junction has historically been, and continues to be, a challenge in spine surgery. Robust pelvic fixation plays an integral role in achieving this goal. The goals of this review are to describe the history of and indications for spinopelvic fixation, examine conventional spinopelvic fixation techniques, and review the newer S2-alar-iliac technique and its outcomes in adult and pediatric patients with spinal deformity. Since the introduction of Harrington rods in the 1960s, spinal instrumentation has evolved substantially. Indications for spinopelvic fixation as a means to achieve lumbosacral arthrodesis include a long arthrodesis (five or more vertebral levels) or use of three-column osteotomies in the lower thoracic or lumbar spine, surgical treatment of high-grade spondylolisthesis, and correction of lumbar deformity and pelvic obliquity. A variety of techniques have been described over the years, including Galveston iliac rods, Jackson intrasacral rods, the Kostuik transiliac bar, iliac screws, and S2-alar-iliac screws. Modern iliac screws and S2-alar-iliac screws are associated with relatively low rates of pseudarthrosis. S2-alar-iliac screws have the advantages of less implant prominence and inline placement with proximal spinal anchors. Collectively, these techniques provide powerful methods for obtaining control of the pelvis in facilitating lumbosacral arthrodesis.

  10. Alanyl-tRNA synthetase genes of Vanderwaltozyma polyspora arose from duplication of a dual-functional predecessor of mitochondrial origin.

    In eukaryotes, the cytoplasmic and mitochondrial forms of a given aminoacyl-tRNA synthetase (aaRS) are typically encoded by two orthologous nuclear genes, one of eukaryotic origin and the other of mitochondrial origin. We herein report a novel scenario of aaRS evolution in yeast. While all other yeast species studied possess a single nuclear gene encoding both forms of alanyl-tRNA synthetase (AlaRS), Vanderwaltozyma polyspora, a yeast species descended from the same whole-genome duplication event as Saccharomyces cerevisiae, contains two distinct nuclear AlaRS genes, one specifying the cytoplasmic form and the other its mitochondrial counterpart. The protein sequences of these two isoforms are very similar to each other. The isoforms are actively expressed in vivo and are exclusively localized in their respective cellular compartments. Despite the presence of a promising AUG initiator candidate, the gene encoding the mitochondrial form is actually initiated from upstream non-AUG codons. A phylogenetic analysis further revealed that all yeast AlaRS genes, including those in V. polyspora, are of mitochondrial origin. These findings underscore the possibility that contemporary AlaRS genes in V. polyspora arose relatively recently from duplication of a dual-functional predecessor of mitochondrial origin.

  13. Urea Unfolding Study of E. coli Alanyl-tRNA Synthetase and Its Monomeric Variants Proves the Role of C-Terminal Domain in Stability

    Science.gov (United States)

    2015-01-01

    E. coli alanyl-tRNA exists as a dimer in its native form and the C-terminal coiled-coil part plays an important role in the dimerization process. The truncated N-terminal containing the first 700 amino acids (1–700) forms a monomeric variant possessing similar aminoacylation activity like wild type. A point mutation in the C-terminal domain (G674D) also produces a monomeric variant with a fivefold reduced aminoacylation activity compared to the wild type enzyme. Urea induced denaturation of these monomeric mutants along with another alaRS variant (N461 alaRS) was studied together with the full-length enzyme using various spectroscopic techniques such as intrinsic tryptophan fluorescence, 1-anilino-8-naphthalene-sulfonic acid binding, near- and far-UV circular dichroism, and analytical ultracentrifugation. Aminoacylation activity assay after refolding from denatured state revealed that the monomeric mutants studied here were unable to regain their activity, whereas the dimeric full-length alaRS gets back similar activity as the native enzyme. This study indicates that dimerization is one of the key regulatory factors that is important in the proper folding and stability of E. coli alaRS. PMID:26617997

  7. Ontogenetic distribution of the transcription factor Nkx2.2 in the developing forebrain of Xenopus laevis

    2011-03-01

    Full Text Available The expression of the Nkx2.2 gene is involved in the organization of the alar-basal boundary in the forebrain of vertebrates. Its expression in different diencephalic and telencephalic regions, helped to define distinct progenitor domains in mouse and chick. Here we investigated the pattern of Nkx2.2 protein distribution throughout the development of the forebrain of the anuran amphibian, Xenopus laevis. We used immunohistochemical and in situ hybridization techniques for its detection in combination with other essential territorial markers in the forebrain. No expression was observed in the telencephalon. In the alar hypothalamus, Nkx2.2 positive cells were scattered in the suprachiasmatic territory, but also in the supraoptoparaventricular area, as defined by the expression of the transcription factor Otp and the lack of xDll4. In the basal hypothalamus Nkx2.2 expressing cells were localized in the tuberal region, with the exception of the arcuate nucleus, rich in Otp expressing cells. In the diencephalon it was expressed in all three prosomeres (P1-P3 and not in the zona limitans intrathalamica. The presence of Nkx2.2 expressing cells in P3 was restricted to the alar portion, as well as in prosomere P2, whereas in P1 the Nkx2.2 expressing cells were located in the basal plate and identified the alar/basal boundary. These results showed that Nkx2.2 and Sonic hedgehog are expressed in parallel adjacent stripes along the anterior-posterior axis. The results of this study showed a conserved distribution pattern of Nkx2.2 among vertebrates, crucial to recognize subdivisions that are otherwise indistinct, and supported the relevance of this transcription factor in the organization of the forebrain, particularly in the delineation of the alar/basal boundary of the forebrain.

    We present a conchal cartilage lily flower graft for correcting depressed and laterally displaced alar cartilage for correction of unilateral cleft nasal deformity.After making a V incision at the base of the columellar and then marginal incisions, the alar cartilages were exposed. A fusiform-shaped cartilage larger than 2.5 cm in length and 1 cm in width was obtained. The midline long axis was scored with a No. 15 knife, and the lateral one third was split. Two-thirds length portions were folded in half, and they became straightened in the shape of a stalk of a lily flower. Two symmetrical one-third length portions were fanned out bilaterally in the shape of the leaf of a lily flower. The stalk portion was positioned in a pocket between the medial crura, and the 2 leaf portions were placed on the dome of the alar cartilages. The marked points of the cleft side and contralateral side were secured with sutures. The V incision at the base of the columellar and the marginal incisions were closed with a V-Y shape. In this technique, the 2 leaf portions were placed on the dome of the alar cartilages and sutured; therefore, the suture holds the dome of the cleft side to the contralateral side without peaking.Thirteen patients (6 male and 7 female subjects; age range, 13-30 years) were operated. Among them, 6 patients were very satisfied, and 5 patients were satisfied with the results. Two patients felt they were improved.We think the conchal cartilage lily flower graft might be a good method for correction of depressed and laterally displaced alar cartilage in unilateral cleft nasal deformity.

  9. Nasal valve surgery.

    2011-04-01

    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.

    A description is presented of Lutzomyia tolimensis sp. nov., a new species of the subgenus Helcocyrtomyia, series sanguinaria. It was collected in dwellings, peridomestic environment and in nearby forest patches located in the foothills of the Andean Central Cordillera, where in 2004–2006 occurred the largest epidemic ever recorded of leishmaniasis in Colombia. The male of this species is differentiated from other members of the series sanguinaria based on the following combination of characters: (i) base of coxite with 0–3 subequal setae, (ii) spines of gonostyle organized in positions 2.1.2, (iii) spines inserted on distal half of gonostyle and (iv) relationship of alar indices. The female is recognized principally by the following characters: (i) palpomere V longer than III, (ii) length of labro-epipharynx and (iii) relationship of the alar indices. PMID:23295748

    In obese subjects, the loss of fat mass during energy restriction is often accompanied by a loss of muscle mass. The hypothesis that n-3 PUFA, which modulate protein homoeostasis via effects on insulin sensitivity, could contribute to maintain muscle mass during energy restriction was tested in rats fed a high-fat diet (4 weeks) rich in 18 : 1 n-9 (oleic acid, OLE-R), 18 : 3 n-3 (α-linolenic acid, ALA-R) or n-3 long-chain (LC-R) fatty acid and then energy restricted (8 weeks). A control group (OLE-ad libitum (AL)) was maintained with AL diet throughout the study. Rats were killed 10 min after an i.v. insulin injection. All energy-restricted rats lost weight and fat mass, but only the OLE-R group showed a significant muscle loss. The Gastrocnemius muscle was enriched with ALA in the ALA-R group and with LC-PUFA in the ALA-R and LC-R groups. The proteolytic ubiquitin-proteasome system was differentially affected by energy restriction, with MAFbx and muscle ring finger-1 mRNA levels being decreased in the LC-R group (-30 and -20 %, respectively). RAC-α serine/threonine-protein kinase and insulin receptor substrate 1 phosphorylation levels increased in the LC-R group (+70 %), together with insulin receptor mRNA (+50 %). The ALA-R group showed the same overall activation pattern as the LC-R group, although to a lesser extent. In conclusion, dietary n-3 PUFA prevent the loss of muscle mass associated with energy restriction, probably by an improvement in the insulin-signalling pathway activation, in relation to enrichment of plasma membranes in n-3 LC-PUFA.

    The nose is important not only for breathing, filtering air, and perceiving olfactory stimuli. Although the face and hands have been mapped, the representation of the internal and external surface of the nose on the primary somatosensory cortex (SI) is still poorly understood. To fill this gap functional magnetic resonance imaging (fMRI) was used to localize the nose and the nasal mucosa in the Brodman areas (BAs) 3b, 1, and 2 of the human postcentral gyrus (PG). Tactile stimulation during fMRI was applied via a customized pneumatically driven device to six stimulation sites: the alar wing of the nose, the lateral nasal mucosa, and the hand (serving as a reference area) on the left and right side of the body. Individual representations could be discriminated for the left and right hand, for the left nasal mucosa and left alar wing of the nose in BA 3b and BA 1 by comparing mean activation maxima and Euclidean distances. Right-sided nasal conditions and conditions in BA 2 could further be separated by different Euclidean distances. Regarding the alar wing of the nose, the results concurred with the classic sensory homunculus proposed by Penfield and colleagues. The nasal mucosa was not only determined an individual and bilateral representation, its position on the somatosensory cortex is also situated closer to the caudal end of the PG compared to that of the alar wing of the nose and the hand. As SI is commonly activated during the perception of odors, these findings underscore the importance of the knowledge of the representation of the nasal mucosa on the primary somatosensory cortex, especially for interpretation of results of functional imaging studies about the sense of smell.

  20. Regional expression of Pax7 in the brain of Xenopus laevis during embryonic and larval development

    2013-12-01

    Full Text Available Pax7 is a member of the highly conserved Pax gene family that is expressed in restricted zones of the central nervous system during development, being involved in early brain regionalization and the maintenance of the regional identity. Using sensitive immunohistochemical techniques we have analyzed the spatiotemporal pattern of Pax7 expression in the brain of the anuran amphibian Xenopus laevis, during development. Pax7 expression was first detected in early embryos in the basal plate of prosomere 3, roof and alar plates of prosomere 1 and mesencephalon, and the alar plate of rhombomere 1. As development proceeded, Pax7 cells were observed in the hypothalamus close to the catecholaminergic population of the mammillary region. In the diencephalon, Pax7 was intensely expressed in a portion of the basal plate of prosomere 3, in the roof plate and in scattered cells of the thalamus in prosomere 2, throughout the roof of prosomere 1, and in the commissural and juxtacommissural domains of the pretectum. In the mesencephalon, Pax7 cells were localized in the optic tectum and, to a lesser extent, in the torus semicircularis. The rostral portion of the alar part of rhombomere 1, including the ventricular layer of the cerebellum, expressed Pax7 and, gradually, some of these dorsal cells were observed to populate ventrally the interpeduncular nucleus and the isthmus (rhombomere 0. Additionally, Pax7 positive cells were found in the ventricular zone of the ventral part of the alar plate along the rhombencephalon and the spinal cord. The findings show that the strongly conserved features of Pax7 expression through development shared by amniote vertebrates are also present in the anamniote amphibians as a common characteristic of the brain organization of tetrapods.

    In the study of central nervous system morphogenesis, the identification of new molecular markers allows us to identify domains along the antero-posterior and dorso-ventral (DV) axes. In the past years, the alar and basal plates of the midbrain have been divided into different domains. The precise location of the alar-basal boundary is still under discussion. We have identified Barhl1, Nhlh1 and Six3 as appropriate molecular markers to the adjacent domains of this transition. The description of their expression patterns and the contribution to the different mesencephalic populations corroborated their role in the specification of these domains. We studied the influence of Sonic Hedgehog on these markers and therefore on the specification of these territories. The lack of this morphogen produced severe alterations in the expression pattern of Barhl1 and Nhlh1 with consequent misspecification of the basolateral (BL) domain. Six3 expression was apparently unaffected, however its distribution changed leading to altered basal domains. In this study we confirmed the localization of the alar-basal boundary dorsal to the BL domain and demonstrated that the development of the BL domain highly depends on Shh. PMID:25741244

    Ligation of tRNAs with their cognate amino acids, by aminoacyl-tRNA synthetases, establishes the genetic code. Throughout evolution, tRNA(Ala) selection by alanyl-tRNA synthetase (AlaRS) has depended predominantly on a single wobble base pair in the acceptor stem, G3•U70, mainly on the kcat level. Here we report the crystal structures of an archaeal AlaRS in complex with tRNA(Ala) with G3•U70 and its A3•U70 variant. AlaRS interacts with both the minor- and the major-groove sides of G3•U70, widening the major groove. The geometry difference between G3•U70 and A3•U70 is transmitted along the acceptor stem to the 3'-CCA region. Thus, the 3'-CCA region of tRNA(Ala) with G3•U70 is oriented to the reactive route that reaches the active site, whereas that of the A3•U70 variant is folded back into the non-reactive route. This novel mechanism enables the single wobble pair to dominantly determine the specificity of tRNA selection, by an approximate 100-fold difference in kcat.

    Full Text Available 【Abstract】Posterior lumbopelvic fixation with iliac screws is the most commonly used method for unstable spinopelvic injuries. It has certain limitations including inability to use distraction along the spinopelvic rod as an indirect reduction maneuver, need for complex 3-dimensional rod contouring and complications such as hardware prominence and soft tissue coverage. In the present case report, we described a surgical technique of lumbopelvic fixation with sacral alar screws for traumatic spinopelvic instability resulted from a unilateral Denis-III comminuted sacral fracture and the L5 burst fracture. On the opposite side of the sacral fracture, caudal screws were implanted into the pedicle of the S1, whereas on the side of sacral fracture, two sacral alar screws were placed parallel to the superior sacral endplate as well as the plane of sacroiliac joint. In addition, horizontal stabilization was conducted with cross-link connections to maintain the longitudinal traction. For sacral fracture associated with traumatic spinopelvic instability, this modified lumbopelvic fixation technique using sacral alar screws makes longitudinal reduction easier, requires less rod contouring, and reduces hardware prominence without compromising the stability.

    Full Text Available Introduction: Refinement of the nose tip can be accomplished by a variety of techniques, but currently, the use of sutures in the nasal tip with conservative resection of the alar cartilage is the most frequently recommended approach. Objective: To classify the nasal tip and to demonstrate the interdomal suture applied to nasal tip refinement in the Caucasian nose, as well as to provide a simple and practical presentation of the surgical steps. Method: Development of surgical algorithm for nasal tip surgery: 1. Interdomal suture (double binding suture, 2. Interdomal suture with alar cartilage weakening (cross-hatching, 3. Interdomal suture with cephalic removal of the alar cartilage (McIndoe technique based on the nasal tip type classification. This classification assesses the interdomal distance (angle of domal divergence and intercrural distance, domal arch width, cartilage consistency, and skin type. Interdomal suture is performed through endonasal rhinoplasty by basic technique without delivery (Converse-Diamond technique under local anesthesia Conclusion: This classification is simple and facilitates the approach of surgical treatment of the nasal tip through interdomal suture, systematizing and standardizing surgical maneuvers for better refinement of the Caucasian nose.

    Full Text Available Background: A surgical technique for correction of complete unilateral cleft lip was done using a minor modification of Millard’s surgical technique. The purpose of this modification is to achieve a good anatomical form of columelia, nostril cill and the position of nasal tip. Purpose: This article presents the correction of the complete cleft lip which was done initially by correction of the slanted columella followed by correction of the nostril sill which was done before the sequence of closing the lip crevice. Case: Correction of a case with complete unilateral cleft lip on a fifteen year old girl using modification of Millard’s surgical technique is presented. Case Management: Rotation incision in the philtrum region was made as introduced by Millard to make a triangular flap. The triangular flap was contralaterally rotated and pulled into the direction of cleft to achieve a normal position of the columella and nasal tip. The lateral side of the ala was incised in circular form down to the alar base and straight through to the direction of cleft formed an alar flap which consisted of ala, clefted and slanted nasal base tissue. The tip of the triangular flap was trimmed and approximated to the alar flap to form a new the nostril sill. Adjustment of the size of the nostrill sill size was achieved during the approximation of those two flaps. The nasal base was built during approximation of the lateral and the medial segment flap or philtrum region and the base of new nostril sill. Surgical correction of the complete unilateral cleft lip including correction of the nostrill sill using approximation of triangular flap and the alar flap was achieved. Conclusion: This surgical technique with minor modification of Millard’s surgical technique can be used for correction of the complete unilateral cleft lip with extremely slanted columella and nasal tip to form thenostril sill.Latar belakang: Koreksi celah bibir komplit satu sisi telah

    Charcot-Marie-Tooth disease (CMT) is the most common cause of inherited peripheral neuropathy, with an estimated frequency of 1/2500. We studied a large family with 17 patients affected by the axonal form of CMT (CMT2). Analysis of the 15 genes or loci known to date was negative. Genome-wide genotyping identified a CMT2 locus in 16q21-q23 between D16S3050 and D16S3106. The maximum two-point LOD score was 4.77 at θ = 0 for marker D16S3050. Sequencing of candidate genes identified a unique mutation, c.986G>A (p.Arg329His), affecting a totally conserved amino acid in the helical domain of cytoplasmic alanyl-tRNA synthetase (AlaRS). A second family with the same mutation and a different founder was then identified in a cohort of 91 CMT2 families. Although mislocation of mutant Arg329His-AlaRS in axons remains to be evaluated, experimental data point mostly to a quantitative reduction in tRNAAla aminoacylation. Aminoacylation and editing functions closely cooperate in AlaRS, and Arg329His mutation could also lead to qualitative errors participating in neurodegeneration. Our report documents in 18 patients the deleterious impact of a mutation in human cytoplasmic AlaRS and broadens the spectrum of defects found in tRNA synthetases. Patients present with sensory-motor distal degeneration secondary to predominant axonal neuropathy, slight demyelination, and no atypical or additional CNS features. PMID:20045102

    Full Text Available Most studies in mammals and birds have demonstrated common patterns of hypothalamic development highlighted by the combination of developmental regulatory genes (genoarchitecture, supporting the notion of the hypothalamus as a component of the secondary prosencephalon, topologically rostral to the diencephalon. In our comparative analysis we have summarized the data on the expression patterns of different transcription factors and neuroactive substances, used as anatomical markers, in the developing hypothalamus of the amphibian Xenopus laevis and the juvenile turtle Pseudemys scripta. This analysis served to highlight the organization of the hypothalamus in the anamniote/amniotic transition. We have identified supraoptoparaventricular and the suprachiasmatic regions in the alar part of the hypothalamus, and tuberal and mammillary regions in the basal hypothalamus. Shared features in the two species are: 1 The supraoptoparaventricular region is defined by the expression of Otp and the lack of Nkx2.1/Isl1. It is subdivided into rostral, rich in Otp and Nkx2.2, and caudal, only Otp-positive, portions. 2 The suprachiasmatic area contains catecholaminergic cell groups and lacks Otp, and can be further divided into rostral (rich in Nkx2.1 and Nkx2.2 and a caudal (rich in Isl1 and devoid of Nkx2.1 portions. 3 Expression of Nkx2.1 and Isl1 define the tuberal hypothalamus and only the rostral portion expresses Otp. 4 Its caudal boundary is evident by the lack of Isl1 in the adjacent mammillary region, which expresses Nkx2.1 and Otp. Differences in the anamnio-amniote transition were noted since in the turtle, like in other amniotes, the boundary between the alar hypothalamus and the telencephalic preoptic area shows distinct Nkx2.2 and Otp expressions but not in the amphibian (anamniote, and the alar supraoptoparaventricular region is defined by the expression of Otp/Pax6, whereas in Xenopus only Otp is expressed.

    Full Text Available The hypothalamus comprises alar, basal and floor plate developmental compartments. Recent molecular data support a rostro-caudal subdivision into rostral (terminal and caudal (peduncular halves. In this context, the distribution of neuronal populations expressing somatostatin (Sst mRNA was analyzed in the developing mouse hypothalamus, comparing with the expression pattern of the genes Orthopedia (Otp, Distal-less 5 (Dlx5, Sonic Hedgehog (Shh and Nk2 homeobox 1 (Nkx2.1. At embryonic day 10.5 (E10.5, Sst mRNA was first detectable in the anterobasal nucleus, a Nkx2.1-, Shh- and Otp- positive basal domain. By E13.5, nascent Sst expression was also related to two additional Otp-positive domains within the alar plate and one in the basal plate. In the alar plate, Sst-positive cells were observed in rostral and caudal ventral subdomains of the Otp-positive paraventricular complex. An additional basal Sst-expressing cell group was found within a longitudinal Otp-positive periretromamillary band that separates the retromamillary area from tuberal areas. Apart of subsequent growth of these initial populations, at E13.5 and E15.5 some Sst-positive derivatives migrate tangentially into neighboring regions. A subset of cells produced at the anterobasal nucleus disperses ventralwards into the shell of the ventromedial hypothalamic nucleus and the arcuate nucleus. Cells from the rostroventral paraventricular subdomain reach the suboptic nucleus, whereas a caudal contingent migrates radially into lateral paraventricular, perifornical and entopeduncular nuclei. Our data provide a topologic map of molecularly-defined progenitor areas originating a specific neuron type during early hypothalamic development. Identification of four main separate sources helps to understand causally its complex adult organization.

    Methane (CH4) is the second most important greenhouse gas emitted in the United States, accounting for about 11% of all US greenhouse gas emissions in 2014. Over 60% of CH4 emissions globally are due to human activity and two of the largest anthropogenic sources of CH4 are waste decomposition in landfills and losses from the energy sector. Indianapolis has been a testbed site for development of methods for quantitative urban-scale greenhouse gas emissions measurements, through the Indianapolis Flux Experiment (INFLUX) since 2010. Multiple airborne mass balance experiments with Purdue University's Airborne Laboratory for Atmospheric Research (ALAR) have been performed in the area to quantify greenhouse gas emissions, since 2008. Previous research has shown that the large landfill in Indianapolis is the only significant point source, emitting 45 ± 14 mols CH4/s or roughly 1/3 of all CH4 emissions. Propane/methane ratios have indicated that all other CH4 emissions were due to leaks in the natural gas distribution system in the city, but not all the sources have been identified. A recent collaborative effort aimed to investigate this further using tower based inversions from INFLUX data, ground based Lagrangian transport modeling using Fourier Transform Spectrometers, and airborne based mass balance experiments using ALAR. Within the 2-week long project there were 4 days with atmospheric conditions that allowed for simultaneous airborne and ground based measurements. Here we will discuss selected outcomes from this effort, including city-wide mass balance measurements from ALAR, our results in light of the FTS observations, and how the results compare to the historical data base for Indianapolis.

  13. Dynamic Kine Magnetic Resonance Imaging in Whiplash Patients and in Age- and Sex-Matched Controls

    Full Text Available The multitude of symptoms following a whiplash injury has given rise to much discussion because of the lack of objective radiological findings. The ligaments that stabilize the upper cervical spine can be injured. Dynamic kine magnetic resonance imaging (dMRI may reveal the pathological motion patterns caused by injury to these ligaments. To compare the findings and motion patterns in the upper cervical spine, 25 whiplash trauma patients with longstanding pain, limb symptoms and loss of balance indicating a problem at the level of C0–C2, as well as matched healthy controls were imaged using dMRI. Imaging was performed with an Intera 1.5 T (Philips Healthcare, USA magnet. A physiotherapist performed the bending and rotation of the upper cervical spine for the subjects to ensure that the movements were limited to the C0–C2 level. An oblique coronal T2- and proton density-weighted sequence and a balanced fast field echo axial sequence were used. The movements between C0–C2 and the signal from the alar ligaments were analyzed. Contact of the transverse ligament and the medulla in rotation was seen in two patients. The signal from the alar ligaments was abnormal in 92% of the patients and in 24% of the control subjects (P<0.0001. Abnormal movements at the level of C1–C2 were more common in patients than in controls (56% versus 20%, P=0.028. Whiplash patients with longstanding symptoms had both more abnormal signals from the alar ligaments and more abnormal movements on dMRI at the C0–C2 level than controls.

    There is still no reliable tool to determine the outcome of the repaired unilateral cleft lip (UCL). The aim of this study was therefore to develop an accurate, reliable tool to measure vertical lip height from photographs. The authors measured the vertical height of the cutaneous and vermilion parts of the lip in 72 anterior-posterior view photographs of 17 patients with repairs to a UCL. Points on the lip's white roll and vermillion were marked on both the cleft and the noncleft sides on each image. Two new concepts were tested. First, photographs were standardized using the horizontal (medial to lateral) eye fissure width (EFW) for calibration. Second, the authors tested the interpupillary line (IPL) and the alar base line (ABL) for their reliability as horizontal lines of reference. Measurements were taken by 2 independent researchers, at 2 different time points each. Overall 2304 data points were obtained and analyzed. Results showed that the method was very effective in measuring the height of the lip on the cleft side with the noncleft side. When using the IPL, inter- and intra-rater reliability was 0.99 to 1.0, with the ABL it varied from 0.91 to 0.99 with one exception at 0.84. The IPL was easier to define because in some subjects the overhanging nasal tip obscured the alar base and gave more consistent measurements possibly because the reconstructed alar base was sometimes indistinct. However, measurements from the IPL can only give the percentage difference between the left and right sides of the lip, whereas those from the ABL can also give exact measurements. Patient examples were given that show how the measurements correlate with clinical assessment. The authors propose this method of photogrammetry with the innovative use of the IPL as a reliable horizontal plane and use of the EFW for calibration as a useful and reliable tool to assess the outcome of UCL repair.

  20. A chain of suprasegmental neuroscillatory circuits: a human brain theory.

    Science.gov (United States)

    Deshmukh, V D

    1988-01-01

    A novel electrophysiological model of human brain electrical activity and functions is proposed. It views the human central nervous system as a chain of three suprasegmental neuroscillatory circuits, namely prosencephalic, mesencephalic, and rhombencephalic. Each circuit consists of a network of periventricular paracrine core neurons, efferent motor plate neurons, and sensory-associative alar plate neurons mediating suprasegmental electroclinical phenomena. The model is based on the exponential analyses of well established human data from the fields of electroencephalography, evoked potentials, wake-sleep spectrum, stages of anesthesia, and a variety of human tremors. This neuroscillatory chain is functionally analogous to the chain of cardiac pacemaker neurons.
