Surgical rehabilitation of nasoalveolar complex in patients with alveolar clefts.

摘要

OBJECTIVE: The objective of this study was to review the outcome of surgical rehabilitation of nasoalveolar complex in patients with alveolar clefts. STUDY DESIGN: Twenty-seven patients (13 female, 14 male) with 4 bilateral and 23 unilateral alveolar clefts who were treated in our clinic during the period between 2002 and 2009 were included in the study. RESULTS: All the patients had oronasal fistulas, and all of them were closed successfully except one. Recurrence of the oronasal fistula was seen in 1 patient. Alar base was supported by onlay cortical bone in most of the patients. Eleven of the canines at the cleft site erupted after the operation in to the grafted area. Seventy-six percent (n = 16) of the 21 patients could be assigned to the successful groups 1 and 2, whereas 24% (n = 5) were assigned to the unfavorable group. There was not any insufficient result. CONCLUSIONS: Bone graft placed along the piriform margin and alar wings during alveolar bone grafting improves the results of nasal correction. Late grafting should be performed at least to support the alar base for nasal symmetry.
