? 2022 Elsevier Inc.Background: Sellar arachnoid cysts (SACs) are rare lesions that require treatment only if symptomatic. The endoscopic endonasal approach has been widely used. Despite their simple cystic appearance and the straight-forward surgical intervention, important associated risks exist, with cerebrospinal fluid (CSF) leak the prevalent risk. Methods: A retrospective analysis of patients with pathologically confirmed SAC between January 2006 and December 2019 was conducted. A homogeneous simple cyst-opening technique and skull base reconstruction with nasoseptal flaps was used. Results: A total of 10 patients were identified (7 women and 3 men; median age, 54.5 years; range, 20–77 years). Of the 10 patients, 8 had had newly diagnosed SACs and 2 patients had had recurrence from a previously microsurgically fenestrated SAC. Eight patients had presented with visual symptoms, one with visual symptoms and fatigue, and one with intractable headaches. Neuro-ophthalmological and endocrinological assessments had revealed visual field deficits in 6, visual acuity decline in 5, and hypopituitarism in 2 patients. The median calculated volume was 1.71 mL (range, 0.27–2.54 mL). Postoperatively, no CSF leak and no further surgical complications were noted. The visual field had improved in 4 of 6 patients and visual acuity had improved in 4 of 5 patients. Anterior pituitary function had improved in 1, worsened in 1, and remained stable in 8 patients. One patient had developed diabetes insipidus. One recurrence was recorded at 54 months postoperatively. Conclusions: The results from the present study have shown that SACs can be effectively treated using a simple cyst-opening technique. The routine use of nasoseptal flaps significantly reduced the risk of CSF leakage without compromising nasal quality of life in the long term or mandating additional incisions. Long-term follow-up is important to monitor for late recurrence.
