Endoscopic Transsphenoidal Cisternostomy for Nonneoplastic Sellar Cysts

Abstract EN

Background and Importance.

Sellar arachnoid cysts and Rathke’s cleft cysts are benign lesions that produce similar symptoms, including optochiasmatic compression, pituitary dysfunction, and headache.

Studies have reported the use of various surgical treatment methods for treating these symptoms, preventing recurrence, and minimizing operative complications.

However, the postoperative cerebrospinal fluid (CSF) fistula and recurrence rate remain significant.

Clinical Presentation.

In this paper, we present 8 consecutive cases involving arachnoid cysts and Rathke’s cleft cysts, which were managed by using drainage and cisternostomy, the intentional fenestration of the cyst into the subarachnoid space, and then meticulously closing sellar floor using dural sutures.

The postoperative images, CSF fistula rate, and the recurrence rate were favorable.

Conclusion.

We report this technique and discuss the benefit of this minimally invasive approach.
