Evaluation of frontal and axial morphology in repaired unilateral cleft lip and palate patients

Abstract

Aim: To evaluate the extent of maxillary arch collapse on cleft vis-a-vis non-cleft side in the same individual presenting with unilateral cleft lip and palate (UCLP) using cone-beam computed tomography (CBCT). Material and methods: 22 children with surgically repaired UCLP who met the inclusion criteria were selected. Following the acquisition of CBCT scans, 14 bilateral landmarks were selected. The distance of the bilateral landmark was calculated from the midsagittal plane on the cleft and non-cleft side for both frontal and axial view. Tracings were done, data obtained was subjected to statistical analysis. Results: In the axial view, zygomatic arch, malar and porion were non-significant but the alveolar crest at the premolar region (p
