ObjectiveTo report our experience of the management of 60 patients with craniopharyngioma with endoscopic endonasal surgery (EES) and evaluate the feasibility and safety of EES for craniopharyngiomas.MethodsThe clinical data of 60 patients with craniopharyngioma who underwent EES between November 2014 and December 2017 were analyzed retrospectively. All patients had vascularized nasoseptal flaps, and the most recent 4 patients had "in situ bone flaps" for better skull base reconstruction. Visual improvements, tumor resection extents, recurrence rates, endocrine functional changes, and surgical complications were evaluated.ResultsThe resection rates were as follows: gross total, 68.3% (41 patients); near total (>95% of tumor removed), 15% (9 patients); subtotal (≥80% of tumor removed), 10% (6 patients); and partial (partial resection <80% of tumor removed), 6.7% (4 patients). Fifty-two patients presented with visual impairment; of these, 46 (88.5%) improved or returned to normal after surgery. Regarding the 32 patients with hypopituitarism before surgery, pituitary function was unchanged in 15 (46.8%), improved or normalized in 4 (12.5%), and deteriorated in 13 (40.6%). Eleven patients (18.3%) suffered from diabetes insipidus before treatment, and 27 more patients had this condition after surgery. Twenty-two patients had hyposmia postoperatively, and 17 patients experienced significant weight gain. Four patients had recent memory loss, and 2 of them had a temporary recent mental disorder. Three (5%) patients had cerebro-spinal fluid leakage after surgery. Three patients (5%) contracted meningitis and were cured with antibiotic treatment. One patient showed recurrence by magnetic resonance imaging re-examination, at the mean follow-up time of 22 months (range, 8-45 months; standard deviation, 11 months).ConclusionsEES can provide surgeons with excellent exposure and can achieve a high extent of removal of most craniopharyngiomas, even those with intraventricular extensions, In our view, vascularized pedicled septal flaps and in situ bony flaps were used in skull base reconstruction.Copyright © 2019 Elsevier Inc.
