Expanded endonasal endoscopic surgery in suprasellar craniopharyngiomas: A retrospective analysis of 43 surgeries including recurrent cases
Copyright © 2019 by the Congress of Neurological Surgeons. BACKGROUND: The role of expanded endonasal endoscopic surgery for primary and recurrent craniopharyngioma is not yet fully established. OBJECTIVE: To report and evaluate our experience with the endoscopic endonasal approach (EEA) for the resection of primary and recurrent craniopharyngiomas. METHODS: This is a retrospective cohort analysis of 43 consecutive EEA procedures in 40 patients operated from September 2006 to February 2012 for suprasellar craniopharyngiomas. In 21 patients (48.8%) the disease was recurrent. We have assessed the surgical results, visual, endocrinological, and functional outcomes and resection rates in this patient cohort. RESULTS: At presentation, 31 (72.1%) patients had visual deficits, 15 patients (34.9%) complained of headaches, 25 patients (58.1%) had anterior pituitary insufficiency, and 14 (32.5%) had diabetes insipidus. Total resection was achieved in 44.2% surgeries, of which 77.3% were in primary lesions and 9.5% in recurrent lesions (P < .001). Vision improved in 92.6% patients and worsened in 2.3%. Complications other than vision were encountered in 25.6% including 9/43 cerebrospinal fluid leak, 2/43 meningitis. A total of 51.9% of patients with preoperative residual anterior pituitary function had new anterior pituitary deficiencies and 42.8% had new diabetes insipidus. There was no mortality. Six patients (14%) had recurrence of disease during the follow-up period (mean 56.8 mo), 5 of which required repeat surgery. CONCLUSION: The EEA can be integrated in the overall management of both primary and recurrent craniopharyngiomas with good results; however, in our series recurrent surgery was associated with significantly lower rates of gross total resection.
