AIM: The aim of the study was to compare the vertical asymmetry of the mandible between a cleft lip palate and normal class I occlusion subjects. Place And Duration: This study was held in the Orthodontics Department of Chandka Medical College Hospital, Larkana for one-year duration from April 2019 to April 2020. Methodology: The sample for this study consisted of a total of 64 patients divided into two groups: Group 1 consisted of 32 patients with a repaired cleft lip and palate without

Group 2 consisted of 32 people. with normal facial morphology and class, I occlusion. Both groups included men and women aged 14 to 16 years [mean age in the cleft group 14.6 years ± 0.73 years and normal group 14.8 years ± 0.73 years]. The index of mandibular asymmetry [condylar, ramal, condylar plus ramal] and the measurements of the gonial angle were computed on a panoramic radiograph. Results: Calculated descriptive statistical measurements between healthy subjects and the cleft lip-palate group showed statistically significant differences in both the condylar and ramal asymmetry index, but in the overall group comparison of the condyle and the fracture height asymmetry index did not show any significant result. Conclusion: In patients with cleft lip and palate the mandible was found to be in proper condition. However, in the unilateral cleft lip and palate, there was a difference in the condylar, ramal and gonial angles between the cleft and non-cleft sides. Keywords: mandible asymmetry, unilateral cleft lip and palate, bilateral cleft lip and palate.
