CLOSURE OF SKULL BASE DEFECTS BY SPHENOID MUCOSAL FLAPS IN ENDOSCOPIC ENDONASAL TRANSSPHENOIDAL SURGERY
Main Article Content
Abstract
Objective: Using sphenoid sinus mucosa flap (SSMF) to reconstruct skull base defects in endoscopic endonasal transsphenoidal surgery (EETS), evaluate effectiveness and complications Methods: 57 patients are treated by EETS, using SSMF with or without other methods to reconstruct the skull base defect(s) Results: Mean age 51,8 ± 13,5, 26 men (45,6%) and 31 women (54,4%). The histopathological feature: pituitary adenoma-36 cases (63,2%), Rathke cyst-15 cases (26,3%), chronic inflammatory lesions-5 cases (8,8%), epidermoid cyst-1 case (1,7%). Kelly grade: 44 cases of grade 0 (77,2%), 9 cases of grade I (15,8%), 3 cases of grade II (5,3%), 1 case of grade III (1,7%). Immediately after surgery, there were 11 cases of nasal discharge (19,6%), 1 case of CSF leak requiring a second surgery to repair the fistula (1,7%) Conclusion: SSMF has advantages such as flexibility, ease of use, restoring anatomical characteristics, promoting the reproliferation of mucosa, reducing local complications. SSMF should be used in any possible case, as a separate method or as an adjunct to others.
