Description
Summary:	This study aims to compare sphenoid sinus variations between unilateral and bilateral cleft lip and palate (CLP) patients and healthy controls using CBCT images. It is notable for its large sample size and comparison of unilateral and bilateral cleft patients, cleft and noncleft sides, and different age groups. Retrospective cohort study. University Hospital. CBCT images of 97 CLP patients (76 unilateral, 21 bilateral) and 97 healthy controls were evaluated.Main Outcome Measures Sphenoid sinus main types, sellar subtypes, clival, and lateral extensions were assessed for all groups. A significant increase in the anterior type was observed in both unilateral and bilateral CLP groups. The bilateral CLP group had a higher prevalence of the lesser wing type. In CLP and control groups, lesser wing, combined type, and lateral type were statistically significantly lower under 13 years of age. The study highlights an elevated prevalence of anterior pneumatization in unilateral and bilateral CLP individuals, emphasizing its significance in surgery planning due to proximity to critical structures like the optic nerve and sphenopalatine artery. The increased prevalence of the lesser wing type in bilateral CLP patients requires extra caution during anterior clinoidectomy. Lower pneumatization rates in CLP patients under 13 suggest their sphenoid sinus development is similar to that of healthy individuals. Understanding these variations is crucial for appropriate surgical planning and avoiding complications during transsphenoidal surgery.
