ABSTRACT
BACKGROUND: Few publications have described the flap design of the secondary cleft alveoloplasty. In this article we describe a modified technique of the classical flap design with the purpose of minimizing injury to the dental papillae and periodontium of the involved dentition. We report our long-term experience, specifically with regards to oronasal fistulae recurrence, wound healing and graft exposure and loss. METHODS: All the patients were operated on using the same technique by a single surgeon. A total of 148 clefts have been operated with this approach, involving 117 patients with complete cleft lip and palate with a follow-up between 12 and 240 months. RESULTS: The most important finding in this study is the excellent wound healing observed in almost all patients. Only three patients (2%) suffered a dehiscence with oronasal fistulae recurrence and bone loss. Another patient lost the graft without fistula recurrence. Minor dehiscence with partial bone loss occurred in 4 patients (2.7%). These patients did not need surgical closure and only superficial exposed bone particles were lost without compromising the clinical outcome. CONCLUSIONS: Our modification presents a flap design that is easy to elevate and mobilize, without disturbing the buccal sulcus or the gingival inter-dental papillae.

OBJECTIVE: To compare palatal dimensions in 6-year-old children with unilateral cleft lip and palate (UCLP) treated by different protocols with those of noncleft children. DESIGN: Retrospective intercenter outcome study. Patients : Upper dental casts from 129 children with repaired UCLP and 30 controls were analyzed by the trigonometric method. SETTING: Six European cleft centers. Main outcome measures : Sagittal, transverse, and vertical dimensions of the palate were observed. STATISTICS: Palate variables were analyzed with descriptive methods and nonparametric tests. Regarding several various characteristics measured on a relatively small number of subjects, hierarchical, k-means clustering, and principal component analyses were used. RESULTS: Mean values of the observed dimensions for five cleft groups differed significantly from the control (p < .05). The group with one-stage closure of the cleft differed significantly from all other cleft groups in most variables (p < .05). Principal component analysis of all 159 cases identified three clusters with specific morphologic characteristics of the palate. A similar number of treated children were classified into each cluster, while all children without clefts were classified in the same cluster. The percentage of treated children from a particular group that fit this cluster ranged from 0% to 70% and increased with age at palatal closure and number of primary surgical procedures. CONCLUSION: At 6 years of age, children with stepwise repair and hard palate closure after the age of two more frequently result in palatal dimensions of noncleft control than children with earlier palatal closure and one-stage cleft repair.
