Evaluation of Mandibular Condyle of Patients With Cleft Lip / Palate

Objectives: In patients with unilateral cleft lip and palate (UCLP), asymmetry is present on the affected side due to the development deficiency of many structures. The aim of this study is to evaluate mandibular condyle morphology and structural features of patients with UCLP using cone beam computed tomography images.
Methods: The study sample consisted of 15 patients with UCLP (9 females and 6 males; mean age: 12.33 ± 2.024) and 15 age and sex matched control patients (9 females and 6 males; mean age: 12.33 ± 2.024). Mandibular condyle morphology was classified as convex, angled, straight, and round. Mandibular condyle structural features were classified as normal, flattening, erosion and osteophyte. The distribution of these categorical variables according to the cleft / non-cleft sides of the patients with UCLP and according to the UCLP (cleft side) / control groups were analyzed using chi-square and Fisher's exact test. The effect of cleft presence on these variables was evaluated using logistic regression analysis. IBM SPSS 25.0 software (IBM Corp., Armonk, NY) was used for statistical analysis.
Results: The distribution of the parameters examined was statistically similar between both the cleft / non-cleft sides of the patients with UCLP and between the UCLP (cleft side) / control groups (p>0.05). There was no statistically significant effect of the presence of cleft on the parameters examined (p>0.05).
Conclusions: The presence of a cleft was not a risk factor for abnormal mandibular condyle morphology and structural features. This study was designed as a pilot study. Future studies with larger sample sizes are required.
