Objectives
The present study aims to evaluate the thickness and radiological patterns of the superior semicircular canal (SSC) in patients with unilateral cleft lip and palate (CL/P).
Methods
Cone beam computed tomography (CBCT) images of the patients were evaluated in axial and Pöschl planes. CBCT images of 84 patients with unilateral CL/P and 168 healthy individual controls were included in the study. Three study groups were established: the CS–CL/P group (cleft side temporal bones of the CL/P patients), NCS–CL/P (non-cleft side temporal bones of the CL/P patients) and the control group. The radiological patterns of SSCs were categorized as dehiscence, papyraceous, normal, pneumatised and thick. The minimum bone thickness of SSC was measured.
Results
It was found that the CS–CL/P group had a higher prevalence for SSCD compared to both the NCS–CL/P group and the control group. CS–CL/P group had a higher prevalence of dehiscence type and papyraceous type compared to the control group. The SSC thickness on the CS–CL/P patients was thinner than the NCS–CL/P patients and the control group sides (p = 0.033 and p < 0.001, respectively).
Conclusions
The mean thickness of SSC was found significantly lower in the CS–CL/P group compared to both the NCS–CL/P group and the control group. The elevated prevalence of dehiscence and papyraceous types in the CS–C/LP group compared to the control group implies that the presence of a cleft may be a predisposing factor for these types.
