Modified sphenoidotomy for isolated sphenoid sinus disease: A series of 117 cases.

Background: The atresia rate of sphenoid ostium after endoscopic sphenoidotomy for isolated sphenoid disease is 9.4%-10.2%.

Aims: To reduce sphenoid sinus ostium atresia rate after sphenoidotomy surgery. Materials and

Methods: The data of patients with isolated sphenoid sinus disease at our hospital between 2015 and 2022 were retrospectively analyzed. The age, gender, disease course, pathology, postoperative follow-up time, anatomy data of sphenoid sinus and postoperative sinus ostium atresia rate were compared between the two groups of patients with traditional sphenoidotomy and modified sphenoidotomy.

Results: A total of 117 patients with isolated sphenoid sinus disease underwent endoscopic sphenoidotomy. There were 76 cases in the traditional sphenoidotomy group, fungus ball in 59.2% of patients, the postoperative sinus ostium atresia rate was 14.5%. There were 41 cases in the modified sphenoidotomy group, fungus ball in 53.6% of patients, and 0 case of sinus ostium atresia. Statistical analysis showed significant differences in postoperative sinus ostium atresia rate. There was no significant difference in age, pathology, postoperative follow-up time, anatomy data of sphenoid, and other data. Conclusions and significance: The modified endoscopic sphenoidotomy may reduce the rate of postoperative sinus ostium atresia.
