Abstract
CONCLUSION: In this series, the split type hypoglossal-facial nerve anastomosis resulted in more favorable outcomes in terms of both facial function and tongue atrophy. OBJECTIVE: This study compared surgical techniques for hypoglossal-facial nerve anastomosis after schwannoma removal and evaluated which technique achieves better facial outcomes and less tongue morbidity. METHOD: This study included 14 patients who underwent hypoglossal-facial nerve anastomosis after schwannoma removal and were followed for more than 1 year. Three surgical techniques were performed: end-to-end, end-to-side, and split anastomoses. Facial palsy and tongue atrophy after anastomosis were evaluated using the scales suggested by House-Brackmann and Martins, respectively. Tumor volume and the time to surgery were also evaluated, and the effects on facial outcomes were analyzed. RESULTS: Overall, nine of 14 (64.3%) patients had favorable facial outcomes, and eight of 14 (57.1%) had favorable tongue outcomes. Regarding facial palsy, five of seven (71.4%) end-to-end, three of four (75%) split, and only one of three (33.3%) end-to-side patients had favorable facial function. Regarding tongue atrophy, all three (100%) end-to-side, three of four (75%) split, and two of seven (28.6%) end-to-end patients had favorable tongue outcomes. The effects of tumor volume and time to surgery on facial outcome were not significant.
