Modified Nasoseptal Flap Technique to Prevent the Recurrence of Rathke's Cleft Cyst

Area of Science:

• Neurosurgery
• Endocrinology
• Ophthalmology

Background:

• Rathke's cleft cysts (RCCs) are benign lesions originating from Rathke's pouch remnants.
• Symptomatic RCCs often require treatment, with cyst fenestration and drainage being a common procedure.
• Standard treatments carry a risk of cyst recurrence.

Purpose of the Study:

• To evaluate the efficacy of a novel modified nasoseptal flap technique in preventing Rathke's cleft cyst recurrence.
• To assess the long-term outcomes of this technique in managing symptomatic RCCs.

Main Methods:

• A prospective, observational study involving 10 patients with symptomatic RCCs.
• Application of a modified nasoseptal flap technique to partially line the cyst wall.
• Preoperative and postoperative evaluations including ophthalmological, endocrine, endoscopic assessments, and MRI.

Main Results:

• All 10 patients experienced symptom relief, with normalized visual fields and pituitary function.
• No recurrence of RCC was observed on follow-up brain MRI, with a median follow-up of 36 months (longest 72 months).
• Endoscopic examination confirmed retained patency of the fenestra in all patients.

Conclusions:

• The modified nasoseptal flap technique is effective in maintaining patency of cyst fenestration.
• This technique successfully avoids Rathke's cleft cyst recurrence on long-term follow-up.
• It represents a promising surgical approach for managing symptomatic RCCs.
