Surgical Outcome of Endoscopic Endonasal Approach for Tuberculum Sella Meningioma

BACKGROUND Management of suprasellar meningioma is still challenging, despite of advances in technology regarding neuronavigation and operating microscope .These difficulties are due to the high risk of visual pathway and vascular involvement. These lesions are traditionally removed through different surgical transcranial approaches. The expanded endoscopic endonasal approaches have become an alternative option for selected suprasellar meningiomas.

PATIENTS AND METHODS 7 patients with suprasellar meningioma were introduced to neurosurgical department Sohag university hospital from January 2015 to January 2018 and treated by endoscopic endonasal surgery. The patients’ clinical outcomes, degrees of tumor removal, and complications were reported.

Results There were (6 tuberculem sellae and 1 planum sphenoidale meningioma). The mean age was 57 years (range from 40 –73 years), and (6 of 7 cases) were women. Gross total resection (GTR) was achieved in all patients (100 %). Post-operative CSF leak occurred in two patients (28.5 %) patient and they respond to conservative treatment for two weeks. Post-operative temporary Diabetes Insipidus occurred in three patients one of them continued for perminant diabetes insipidus. No deaths, vascular injury, Sphenoiditis, septal perforation, epistaxis or general complication.

Conclusion Endoscopic endonasal approach for suprasellar meningioma treatment is a safe and effective alternative to the traditional microscopic procedure.
