Abstract

Objective This aim of this study was to address the outcome of endoscopic reconstruction of the sellar floor by extended inferior turbinate flap.

Patients and Methods This is a retrospective study of 34 patients with a recurrent pituitary tumor. They were treated between March 2018 and December 2021 by endoscopic extended endonasal approach with the reconstruction of the sellar floor by an extended posterior pedicle inferior turbinate flap. The clinical and radiological follow-up was performed immediately postoperation and regularly every 3 months up to 1 year, and the available data from the last follow-up visit were included in the analysis.

Results The patients' age ranged between 40 and 65 years, with a slight female predominance (55.9%). Headache was the main presentation (47.1%), and functional tumors were found in 50.0% patients. Visual disturbances were field defects among 61.8% and papilledema among 52.9% patients. Preoperative endoscopy revealed postseptectomy as the significant finding (73.5%), followed by postseptectomy and adhesion (14.7%) and finally postseptectomy and hypertrophied inferior turbinate (11.8%). Total tumor resection was achieved in 76.5%, visual improvement was recorded in 52.9%, and no complications were reported in 82.4% patients. Cerebrospinal fluid (CSF) leak was not reported in any of the studied patients. Finally, total resection was significantly associated with younger age, non-functioning tumor and improvement of headache.

Conclusion The extended inferior turbinate flap is an effective and safe approach for sellar floor reconstruction in endoscopic endonasal surgery for recurrent pituitary tumors. The extension overcomes the relatively small inferior flap and its limited arc of rotation.
