Long-Term Postoperative Cone-Beam Computed Tomography Analysis of Secondary Bone Grafting in 79 Patients With Unrepaired Alveolar Clefts.

Purpose: This study used cone-beam computed tomography (CBCT) analysis to assess the long-term radiographic outcomes of early secondary alveolar bone grafting.

Patients And Methods: The most recent postoperative CBCT scans of 79 alveolar cleft patients who underwent anterior iliac crest bone grafting by a single surgeon over a 6-year period and met all inclusion criteria were analyzed using a modified assessment tool. Clefts were measured vertically, horizontally, and superiorly in terms of nasal support and then assigned corresponding scores of 0 to 4 to help determine radiographic success.
