Abstract

Abstract: Objective: To evaluate condylar and ramus mandibular vertical asymmetry of patients affected by unilateral cleft lip and palate (UCLP). Methods: The study included an experimental group of 25 UCLP patients and a control group of 25 healthy subjects. Cone-beam computed tomography (CBCT) images were taken. Measurements of mandibular condyle, ramus and condyle plus ramus heights were analyzed, as well as asymmetry indices. Paired samples t test and an independent t test of the measurements were performed using SPSS 17.0. Results: There was a statistically significant difference between the normal and cleft sides in the condyle height and condyle plus ramus height in the UCLP group. The independent t test showed a statistically significant difference between the cleft group and the control group in condyle plus ramus height and asymmetry index values. Conclusion: The condyle height and condyle plus ramus height were significantly lower in the cleft side in the UCLP patients, demonstrating vertical asymmetry. There was significant difference in condyle plus ramus height and asymmetry index between UCLP patients and the control.
