Nonsyndromic Alar Clefts: Report of Five Brazilian Patients

Nonsyndromic alar clefts are rare and they range from a small notch to variable size of clefts of the nasal ala. Usually they are restricted to the alar region, but other minor anomalies such as midline nasal sinuses and small midline or ""northbound"" clefts can be present. To date all reported cases of nonsyndromic alar clefts have been sporadic. Here we report on five new cases of isolated and nonsyndromic alar clefts. (C) 2009 Wiley-Liss, Inc.

Enxerto composto auricular na reconstrução da asa nasal

O nariz ocupa o centro da face, o que torna pequenas assimetrias e imperfeições evidentes. Uma de suas subunidades é a asa nasal, região que exige não apenas resultados estéticos, mas também funcionais, em sua reconstrução, tornando-se um desafio ao cirurgião plástico. Neste artigo são descritos 3 casos em que foi utilizado enxerto composto auricular para reconstrução da asa nasal. Os enxertos apresentaram integração total, com resultados estéticos e funcionais adequados. Segundo revisão da literatura, não há diferença nos índices de complicação comparando-se os enxertos com os retalhos locais e, a longo prazo, a cartilagem auricular tende a manter-se no formato moldado, sofrendo raras distorções e mínima ou nenhuma absorção, diferentemente das cartilagens costais e dos enxertos ósseos. O enxerto composto auricular é uma técnica versátil e segura, com excelentes resultados na reconstrução da asa nasal e com baixa morbidade das áreas doadoras, cumprindo com eficiência seu objetivo reparador.

Birhombic flap, a modified bilobed flap, for repair of nasal defect

BACKGROUND Reconstruction of longitudinal defects of the lateral nasal alar might be challenging. Reconstruction with a bilobed flap is common for round defects normally the bilobed flap is less suited for longitudinal defects. OBJECTIVE We describe a birhombic flap for longitudinal defect. METHODS Demonstration of the technique and practical application for this kind of reconstruction. RESULTS The bilobed flap is a very useful flap for lateral nasal tip or distal alar reconstruction. We show that a small modification of the flap allows to cover also longitudinal defects on the lateral tip of the nose. As the first lobe movement corresponds more to the rhomboid transposition flap, we prefer to call it birhombic flap. CONCLUSION The birhombic flap has its place in reconstructive surgery. This flap has a specific indication and precise advantages to other repairs in particular to the bilobed flap.

Evaluation of Primary Cleft Nose Repair: Severity of the Cleft Versus Final Position of the Nose

Background: Since 1957, when the concept of rotation-advancement repair was introduced by Millard, this technique has become the procedure of choice for unilateral cleft lip worldwide. More recently, modifications described by Noordhoof, Mohler, Skoog, and McComb started being jointly performed so that better results could be obtained. In this study, the nasal position was evaluated and related to the size of the cleft. The primary unilateral cleft lip repair was performed through a modified technique. Methods: Forty-five patients with unilateral cleft lip underwent primary surgical repair through this technique. To analyze aesthetic results, a severity classification of deformities and a scoring system for evaluation of the results were established based on nasal alar lateralization, dome position, alignment of bone segments, and deviation of the columella. Results: By means of the established system, 26.6% of mild forms, 13.4% of moderate forms, and 60% of severe forms were observed. Among aesthetic results, 17.8% were found to be good, and 82.2% were considered excellent. Among aspects considered negative, late deformity of the lower lateral cartilage prevailed. Conclusions: Through the presented evaluation, the authors observed that there was no relation between severity of the cleft and final position of the nose. Among the 27 patients considered to have had severe forms of cleft deformity, 22 were classified as excellent results (81.5%). To obtain better results along time, technical refinements and the critical analysis of results must be performed on a routinely basis.

Frontonasal Dysgenesis, First Branchial Arch Anomalies, and Pericallosal Lipoma: A New Subtype of Frontonasal Dysgenesis

We report on two unrelated Brazilian boys with craniofacial anomalies that involve the frontonasal process and the first branchial arch associated with pericallosal lipoma. To our knowledge this condition seems to have been reported only once previously, but may represent a new condition within the group of the frontonasal dysgenesis. Clinical and imaging data, phenotypic evolution, and differential diagnosis are discussed. (C) 2010 Wiley-Liss, Inc.

Oral-Nasal-Ocular Cleft: The Greatest Challenge Among the Rare Clefts

Introduction: Number 3 cleft or oral-nasal-ocular cleft is a well-known entity that was described by Morian over a century ago. This malformation is a paranasal-medial orbitomaxillary cleft running across the lacrimal segment of the lower eyelid and over the lacrimal groove. The Tessier number 3 naso-ocular cleft represents one of the most difficult and challenging malformations to correct for the reconstructive surgeon. We have conducted a retrospective analysis of our series consisting of 21 cases. Objective: The objective was to review the functional outcome and aesthetic results of the different techniques applied for each case. Materials and Methods: From 1997 to 2007, 21 patients with a Tessier number 3 cleft were treated in our craniofacial units. The clinical findings, tomographic studies, and surgical procedures were reviewed and analyzed. We have discussed our protocol of the treatment. Results: We have treated facial malformation in 2 craniofacial centers. Fourteen patients were evaluated in the first year of their life, with an average age at presentation of 3 years. Twelve patients were female, and 9 were male; 6 patients had amniotic bands in limbs, 5 patients had an association with Tessier number 11 cleft, 3 patients with number 9 cleft, and 1 with number 7 cleft. Related to cleft lip, 10 patients had bilateral cleft lip, and 8 patients had unilateral cleft lip. Three patients did not have any involvement of the upper lip. The alar base was deviated upward in 19 patients, 11 cases had severe anatomic alteration with the lateral border of the ala above the medial canthus, and 8 cases had a mild dislocation. Nine cases of lacrimal duct obstruction and 8 cases of lacrimal duct extrophy were identified. Twelve patients had a lower eyelid coloboma of varying grades, and there were 2 cases of microblepharia. Aiming the soft tissue reconstruction, eyelid, nose, and upper lip were evaluated regarding their position, absence of tissue, and position of medial canthus and ala. Twelve of our patients underwent correction in the same moment, their medial canthus rotated upward and the ala downward, using the contralateral side as the reference. The lip was treated using a Millard-like technique. Neo-conjunctivorhinostomy was performed in the same moment in 2 patients or later in 1 case. Four patients had plagiocephaly due to the cranial involvement, and they were submitted to cranioplasty. Three had neurosurgical approach and advancement of the frontal bandeau. One adult patient received an acrylic plate to reshape the frontal area. Conclusions: Tessier number 3 cleft is one of the most difficult and challenging malformations to correct for the reconstructive surgeon. Besides the difficulties of its treatment, patients with Tessier number 3 cleft may achieve good results when the team has good skills.

Histological comparison of the alar nasal cartilages in unilateral cleft lip

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.

Modified technique to increase nostril cross-sectional area after using rib and septal cartilage graft over alar nasal cartilages

PURPOSE: Describe a modified technique to increase nostril cross-sectional area using rib and septal cartilage graft over alar nasal cartilages. 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 (c); 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.

Evaluation of secondary functional cheilorhinoplasty during growth of cleft patients with residual lip and nasal deformities

PURPOSE: The aim of the study was to evaluate the clinical outcomes of secondary functional cheilorhinoplasty of residual lip and nasal deformities caused by muscular deficiency in cleft patients. PATIENTS AND METHODS: During a 4-year period, 31 patients underwent cheilorhinoplasty, including complete reopening of the cleft borders and differentiated mimic muscle reorientation. In 21 patients, remarkable residual clefts of the anterior palate were also closed. Simultaneous alveolar bone grafting was performed in 15 patients. The minimum follow-up was 1 year. Cosmetic features evaluated were spontaneous facial appearance and changes in position of the nasal floor and the philtrum. The width of the alar base was measured. For functional outcomes, deficiency during mimic movements was evaluated, using standardized photographs taken preoperatively and postoperatively. The final results, judged according to defined criteria with several clinical factors, were compared. RESULTS: Cosmetic and functional improvement was achieved in all patients. In young patients (aged 4 to 9 years), the improvements were noteworthy. There were no differences in outcomes between the groups with and without simultaneous grafting, except for unilateral cases with minor muscular deficiency, in whom bone grafting before cheilorhinoplasty led to better results. CONCLUSION: In cases of major muscular deficiency, early cheilorhinoplasty should be performed at age 7 years, without waiting for the usual timing of bone grafting. In minor and moderate cases, the operation can ideally be done in combination with bone grafting.

Photographic assessment of nasal morphology following rapid maxillary expansion in children

OBJECTIVE: The aim of the present study was to use facial analysis to determine the effects of rapid maxillary expansion (RME) on nasal morphology in children in the stages of primary and mixed dentition, with posterior cross-bite. MATERIAL AND METHODS: Facial photographs (front view and profile) of 60 patients in the pre-expansion period, immediate post-expansion period and one year following rapid maxillary expansion with a Haas appliance were evaluated on 2 occasions by 3 experienced orthodontists independently, with a 2-week interval between evaluations. The examiners were instructed to assess nasal morphology and had no knowledge regarding the content of the study. Intraexaminer and interexaminer agreement (assessed using the Kappa statistic) was acceptable. RESULTS: From the analysis of the mode of the examiners' findings, no alterations in nasal morphology occurred regarding the following aspects: dorsum of nose, alar base, nasal width of middle third and nasal base. Alterations were only detected in the nasolabial angle in 1.64% of the patients between the pre-expansion and immediate post-expansion photographs. In 4.92% of the patients between the immediate post-expansion period and 1 year following expansion; and in 6.56% of the patients between the pre-expansion period and one year following expansion. CONCLUSIONS: RME performed on children in stages of primary and mixed dentition did not have any impact on nasal morphology, as assessed using facial analysis.

Retalho de rotação para defeitos da asa nasal

Surgical defects of the alar lobule can be difficult to repair with functional and aesthetically desirable results. Skin grafts are smoother and paler than the nasal skin. Flaps from the cheek and proximal nose can bridge the alar crease, resulting in obstruction. The authors describe a technique to repair nasal ala defects, with maintenance of the cosmetic unit, without airflow disturbance.

Extraoral alar base cinch. A modification for the technique

The alar base widening is directly related to the Le Fort I osteotomy which could lead to an undesirable facial change if not adequately controlled transoperatively. Several surgical techniques to control the lateralization and widening of the nasal base have been described in the literature. The extraoral technique, first described by Shams and Motamedi in 2002 seems to make this procedure more predictable and reliable. The authors preset a modification for that technique. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

The medial based bi- or trilobed flap for repair of distal alar defects

BACKGROUND Reconstruction of defects of the lateral nasal ala might be challenging. Reconstruction with a bi- or trilobed flap is common. The laterally based bi- or trilobed flap for defects of the distal ala or lateral tip of the nose produces mostly tissue protrusion in the nasal groove which is aesthetically unpleasant. Why not use more the medially based bi- or trilobed flap? OBJECTIVE To describe the utility of bilobed and trilobed flaps for alar defects insisting on the design of medially based flaps. METHODS To show the technique and practical application for this kind of reconstruction. RESULTS The bi- and trilobed flaps are useful for defect repair between the lateral nasal tip and the distal ala. We observed that in most cases the flap based medially respects anatomical subunits better than the laterally based flap for medium-sized defects of the distal ala of the nose. CONCLUSION I suggest that the bi- and trilobed flaps for repair of the lateral tip/distal ala should more often be medially based. This flap has a specific indication and precise advantage compared to other reconstructions, especially to the laterally based multilobed flaps in this specific indication.

Pituitary Macroadenoma Presenting As A Nasal Tumor: Case Report.

Pituitary macroadenomas are rare intracranial tumors. In a few cases, they may present aggressive behavior and invade the sphenoid sinus and nasal cavity, causing unusual symptoms. In this paper, we report an atypical case of pituitary adenoma presenting as a nasal mass. The patient was a 44-year-old woman who had had amenorrhea and galactorrhea for ten months, with associated nasal obstruction, macroglossia and acromegaly. Both growth hormone and prolactin levels were increased. Magnetic resonance imaging showed a large mass originating from the lower surface of the pituitary gland, associated with sella turcica erosion and tumor extension through the sphenoid sinus and nasal cavity. Histopathological analysis demonstrated a chromophobe pituitary adenoma with densely packed rounded epithelial cells, with some atypias and rare mitotic figures. There was no evidence of metastases. Macroadenoma invading the nasal cavity is a rare condition and few similar cases have been reported in the literature. This study contributes towards showing that tumor extension to the sphenoid sinus and nasopharynx needs to be considered and investigated in order to make an early diagnosis when atypical symptoms like nasal obstruction are present.
