The palatal mucosal graft: The adequate posterior lamellar reconstruction in extensive full-thickness eyelid reconstruction.

INTRODUCTION: Full-thickness eyelid defects exceeding 25% of the eyelid width should benefit from a skillful, immediate and simultaneous reconstruction of two layers; anterior and posterior lamella. In this article, we recall, through an original series of cases, the possibility of using a palatal fibromucosal graft during the reconstruction of the posterior lamella as well as the modalities of its optimal use. PATIENTS AND METHODS: Retrospective study, including 8 patients with an extensive full-thickness eyelid defect affecting more than half of the upper and/or lower eyelid, after tumor excisions. 4 cases were involved in lower eyelid reconstruction, 2 in upper one and 2 in both. Posterior lamella was reconstructed using a palatal mucosal graft. Anterior lamella was reconstructed using different flaps: Esser-Mustardé flap, medially and laterally based orbicularis oculi myocutaneous flap, Tripier and orbitonasolabial flaps. Mean follow-up was 12.75 months. RESULTS: The survival rate of grafts and flaps was excellent with only one flap border necrosis. The donor site healed in an average time of 3 weeks. Functional recovery, complete eye closure and opening, was obtained in all cases. Lining, texture and color was considered satisfactory in all cases. CONCLUSION: The palatal mucosal graft provides a good and lasting structural support to the eyelid, which is essential for the inferior eyelid, especially when combined with a flap. Slight overcorrection is recommended.

Facial growth in children with complete cleft of the primary palate and intact secondary palate.

PURPOSE: Children with unoperated cleft lip/palate have nearly normal facial growth, whereas patients who have had labiopalatal repair often exhibit midfacial retrusion. The aim of this study was to compare cephalometric data in patients with repaired unilateral or bilateral complete cleft lip/alveolus (UCCLA or BCCLA) with patients with repaired unilateral or bilateral complete cleft lip/palate (UCCLP or BCCLP). This study might provide insight into the etiology of impaired facial growth in patients with repaired cleft lip/palate. MATERIALS AND METHODS: This was a retrospective, cross-sectional analysis of nonsyndromic patients with UCCLA, BCCLA, UCCLP, and BCCLP. Angular and linear measurements of the midfacial region were made on traced lateral cephalograms. Paired t tests were used to compare each group with normative controls from the Michigan Growth Study. Multivariate analysis of variance was used to determine possible differences among the groups. RESULTS: There were 77 patients (38 male and 39 female) with a mean age of 11.2 years (range, 6 to 16 years; UCCLA, n = 25; BCCLA, n = 7; UCCLP, n = 18; and BCCLP, n = 27). There was no significant difference in midfacial position between the UCCLA and BCCLA groups and noncleft age-matched controls. In contrast, the maxilla in patients with UCCLP and BCCLP was significantly smaller and more retruded (P < .05) compared with patients with UCCLA and BCCLA and controls. CONCLUSIONS: Children with UCCLA and BCCLA appear to have normal midfacial growth, whereas the maxilla in children with UCCLP and BCCLP is small and retrusive. This study suggests that the presence and/or repair of the secondary palate is responsible for midfacial hypoplasia in these patients.

Use of rotation flap in repair of cleft palate and velopharyngeal insufficiency.

Although cleft palate anomaly is frequent, the criterion standards in surgical treatment have not been determined yet. There are a few techniques described for cleft palate repair owing to the limited tissue in the palatal mucosa, the rigid structure of the palatal mucosa, and the limited vascularity of the hard palate. In this study, a novel cleft palate repair technique based on separating the soft palate from the hard palate as a musculomucosal flap and using it as a rotation flap has been described. The operation is evaluated individually for each anomaly because variations occur in the surgical technique according to the extension of the cleft toward the teeth in the palate. This operation was performed on a total of 28 patients (17 girls and 11 boys) aged between 1.5 and 16 years and presented to our clinic. Patients were assessed for speech analysis outcomes, tympanogram values, hearing functions, magnitude of palatal lengthening during the operation, and rate of fistulae. Statistically significant differences in values of the speech analysis and the audiometric assessment were determined between before and 6 months after surgery. Complete recovery of otitis was observed 1 month after surgery without another treatment in 9 (42.8%) of 21 patients who were detected to have serous otitis media preoperatively. Tension-free closure, lower risk of fistula, good restoration of velopharyngeal functions, ability to be performed on all types of cleft palate, ability to provide a good intraoperative exposure, and being a single stage seem to be the most important advantages of this technique.

Three-layer closure of an oroantral-cutaneous defect.

Reconstruction of oroantral defects, which are usually caused by tumor resection, is challenging. These defects become an even more difficult problem when they comprise multiple layers including oral mucosa, subcutaneous tissue, muscle and skin. This paper describes such a case in which a three-layer closure using a palatal flap, a buccal fat pad flap and a local skin flap was successfully performed.

Two-stage palatoplasty using a modified Furlow procedure.

A two-stage palatal repair using a modification of Furlow palatoplasty is presented. The authors investigate the speech outcome, fistula formation and maxillary growth. In a prospective, successive cohort study, 40 nonsyndromic patients with wide cleft palate were operated on between March 2001 and June 2006 by a single surgeon. 10 patients in the first cohort underwent a Furlow palatoplasty (control group). In 30 patients in the second cohort a unilateral myomucosal cheek flap was used in combination with a modified Furlow palatoplasty (study group). The hard palate was closed in both groups 9-12 months later. The Bzoch speech quality score was superior in the study group, and the hypernasality was significantly reduced in the study group. Overall fistula formation was 0%. At the time of hard palate reconstruction palatal cleft width was significantly reduced. Relative short-term follow up of maxillary growth was excellent. There were no postoperative haematomas, infections, or episodes of airway obstruction. This technique is particularly encouraging, because of better speech outcome, absence of raw surfaces on the soft palate, no fistula formation, and good maxillary growth. Further follow-up is necessary to determine the long-term effects on facial development.

Full-thickness reconstruction of the eyelid with rotation flap based on orbicularis oculi muscle and palatal mucosal graft: long-term results in 12 cases.

BACKGROUND: Numerous techniques have been proposed for full-thickness eyelid reconstruction. Previously, we reported full-thickness eyelid reconstruction with a rotation flap based on the orbicularis oculi muscle and palatal mucosal graft. Here, we report long-term results in 12 cases. METHODS: After confirmation of defect size, the mucosal defect was covered with a split-thickness palatal mucosal graft. The rotation flap was elevated at the lateral orbital region and the skin defect was covered. Seven cases were reconstructions after tumour excision and five cases were for lagophthalmos after trauma. In cases of tumour excision, five cases had full defects of the lower eyelid and two cases had defect of the lower eyelid lateral to the punctum. In the cases of lagophthalmos, four cases had upper eyelid contracture and one had lower eyelid contracture. RESULTS: Postoperatively, one case showed severe venous congestion of the flap, which led to scleral show. In the other 11 cases, there were no complications, and cosmetic results were excellent. CONCLUSIONS: With our method, cosmetically good results can be obtained in either upper or lower eyelids. In the rotation flap based on the orbicularis oculi muscle, the undermined area is small, invasion is minimal, and the effects of scar contracture can be minimised. Minimal shrinkage of palatal mucosal grafts prevents the reconstructed eyelid from sagging. In only one case, poor design of the flap led to flap congestion. However, this complication can be avoided with the proper design.

Cleft palate repair using a marginal musculo-mucosal flap.

OBJECTIVE: To describe a modified procedure consisting of a mucoso-periosteal flap palatoplasty with a marginal musculo-mucosal flap (3M flap). This is also the first report of a primary repair for complete cleft palate using the 3M flap. We describe the lengthening effect of the nasal mucous layer of the soft palate and evaluate the fistula formation rate associated with this method. METHODS: This procedure has been performed on 21 patients with unilateral complete clefts and on 27 patients with incomplete clefts. A mucoso-periosteal flap raised from the hard palate was used mainly for closure of the cleft and not for the push-back. The 3M flap repaired the deficit of the nasal mucosa, making sure that the soft palate was lengthened. Intravelar veloplasty was performed also. RESULTS: The dimension of the nasal mucosal defect that can be filled with the 3M flap is 10 to 12 mm in length, oriented anterior-posterior, and 15 to 20 mm wide. Oronasal fistula formation was recognized in only 3 of 48 cases (2 of 21 complete clefts, 1 of 27 incomplete clefts) and were located at the hard-soft palate junction at the anterior portion of the 3M flap. CONCLUSIONS: This method has the theoretical advantages of (1) preventing fistula formation by filling the tissue deficiency with the 3M flap; (2) achieving better velopharyngeal function due to elongation of the soft palate and retropulsion of the muscular bundle, utilizing the 3M flap; and (3) minimizing maxillary growth retardation by adopting a non-push-back method of hard palate repair.
