Objective   To report our results and the technical details of fully endoscopic resection of @entity5513 . Design   Prospective observational study. Setting   A single academic institution involving neurosurgery and neurotology. @entity1   Twelve consecutive @entity1 who underwent fully endoscopic resection of a @entity5513 . Main Outcome Measures   Hearing preservation, based on the American Association of Otolaryngology-Head and Neck Surgeons (AAO-HNS) score as well as the Gardener and Robertson Modified Hearing Classification (GR). Facial nerve preservation based on the House-Brackmann (HB) score. Results   All @entity1 successfully underwent gross total resection. Facial nerve preservation rate was 92% with 11 of 12 @entity1 retaining an HB score of 1/6 postoperatively. Hearing preservation rate was 67% with 8 of 12 @entity1 maintaining a stable AAO-HNS grade and GR score at follow-up. Mean @entity5 size was 1.5 cm (range: 1-2 cm). No @entity1 experienced postoperative @entity5173 , @entity281 , or @entity129 for a complication rate of 0%. Mean operative time was 261.6 minutes with an estimated @entity190 of 56.3 mL and average length of hospital stay of 3.6 days. Conclusion   A purely endoscopic approach is a safe and effective option for hearing preservation surgery for @entity5513 in appropriately selected @entity1 .
