Summary
Endoscopic cavernous sinus surgery offers a safe and effective approach for pituitary adenomas with invasion. This minimally invasive technique significantly reduces surgical morbidity while achieving radical tumor removal and hormonal remission.
Area of Science:
- Neurosurgery
- Endocrinology
- Oncology
Background:
- Cavernous sinus surgery presents significant challenges due to the region's critical neurovascular structures.
- High morbidity rates have historically been associated with traditional open surgical approaches.
Purpose of the Study:
- To evaluate the efficacy and safety of a purely endoscopic approach for pituitary adenomas with cavernous sinus invasion.
- To assess the outcomes of radical tumor removal, hormonal remission, and overall morbidity in patients treated endoscopically.
Main Methods:
- A cohort of 65 patients with pituitary adenomas and intraoperative cavernous sinus invasion underwent a purely endoscopic surgical procedure.
- Patients were followed for a minimum of 6 months (mean 51.2 months) post-surgery.
Main Results:
- No perioperative mortality and extremely low morbidity were observed.
- Radical tumor removal was achieved in 21 of 35 nonfunctioning adenomas.
- Hormonal remission was obtained in 13 of 30 functioning adenomas, with minimal complications like CSF leaks and hypopituitarism.
Conclusions:
- The purely endoscopic approach is a safe and effective surgical option for pituitary adenomas invading the cavernous sinus.
- Endoscopic surgery allows for precise tumor definition, histopathological diagnosis, and effective tumor debulking, potentially improving adjuvant therapy response.
