Özet

Background: Epidermoid and dermoid tumors in the sellar region are rare. These cystic lesions are a surgical challenge, as the thin capsule adheres firmly to nearby structures. A case series of 15 patients is presented. Methods: The patients were operated on in our clinic between April 2009 and November 2021. The endoscopic transnasal approach (ETA) was used. Lesions were located in the ventral skull base. In addition, the literature was reviewed to compare clinical features and outcomes of ventral skull-base epidermoid/dermoid tumors operated on via ETA. Results: In our series, removal of cystic contents and tumor capsule (gross total resection: GTR) was achieved in 3 patients (20%). GTR was not possible for the others, because of adhesions to vital structures. Near total resection (NTR) was achieved in 11 patients (73.4%), and subtotal resection (STR) in 1 (6.6%). At a mean follow-up of 55 ± 26.27 months, there were no cases of recurrence requiring surgery. Conclusion: Our series demonstrates that ETA is suitable for resection of epidermoid and dermoid cysts in the ventral skull base. GTR cannot always be the absolute clinical aim, because of inherent risks. In patients with expected long-term survival, the aggressiveness of surgery should be weighed on an individual risk/benefit basis.
