AbstractEven being equipped with advanced surgical navigation systems, thorough analysis of patient's imaging diagnosis before procedures is still of great necessity for the operators. This study aimed to explore the morphological changes of sphenoid sinus lesions as observed on computed tomography (CT), and further carry out the fenestration of sphenoid sinus under guidance of the CT.A retrospective analysis of the characteristics of CT images was performed. The outcomes of three kinds of nasal endoscopic surgeries on benign lesions of sphenoid sinuses were investigated. For the 128 patients included, nasal-cavity-olfactory cleft pathway was performed in 64 patients, the Messerklinger pathway was adopted in 54 patients, while Wigand pathway was performed in the rest 10 patients.After follow-up visit, the drainage at the fenestration site of sphenoid sinus was found to be smooth, the symptoms were completely controlled, and no severe complication was reported during or after the surgery. No significant difference was observed in the curative effects among the 3 groups.CT of the paranasal sinus can guide the procedures of sphenoid sinus fenestration. No statistically significant differences were exhibited in terms of the amount of bleeding, surgical time and days of hospitalization among the 3 groups.
