Sphenoid Sinus Volumes of Patients with Unilateral Cleft Lip and Palate.

Objective: There is only one study in the literature in which 3D evaluation of sphenoid sinus volume in patients with cleft lip and palate was used. This shows that this issue has not been adequately evaluated. The present study aimed to compare the volume of the sphenoid sinuses in patients with cleft lip and palate on cone-beam computed tomography images, and to compare them with healthy controls. The high variability of sphenoid sinus volumes poses a risk for iatrogenic lesions during surgical procedures. Because the degree of pneumatization due to increased volume increases the likelihood of exposure of vital neurovascular structures such as the internal carotid artery, maxillary nerves, and optic nerves.

Design: Retrospective cohort study.

Setting: University Hospital.

Patients: A total of 64 patients (32 cleft palate, 32 controls) over 18 years of age who had sphenoid sinuses in the image area were included in our study.

Outcomes: Sphenoid Sinus Volume.

Results: When the groups were compared in terms of total sinus volume, there was a statistically significant difference between them. Total sinus volume was significantly mean 2.806,87 mm lower in patients with cleft lip and palate compared to the healthy group ( = .015).

Conclusion: To be aware this lower volume of the sphenoid sinus in cleft lip and palate patients will be useful for the surgical approach to sphenoid sinus. However, the literature on the subject is insufficient, more comprehensive clinical and radiological studies are needed on a larger sample.
