Abstract
OBJECTIVES: We reviewed the long-term results of facial nerve repair in a tertiary head and neck institution in the north of England. METHODS: We performed a case notes review of patients who had facial nerve repair over a 10-year period and had completed 24 months of follow-up. RESULTS: The study population comprised 18 female patients and 24 male patients, with an overall mean age of 53.2 years (range, 16 to 80 years). Of the 24 patients who had a cable nerve graft, the greater auricular nerve was used in 15 cases. The sural nerve was used as the donor in a cross-facial nerve graft in 9 patients. Sixteen patients had transposition nerve repair: hypoglossal and ansa cervicalis in 7 and 9 cases, respectively. Two patients had primary anastomosis after surgery for extensive malignant tumors. In this series, no patients achieved a House-Brackmann (HB) grade of II. Overall, the HB grades III, IV, and V were the best postoperative facial nerve functions achieved in 11.9%, 33.3%, and 26.2% of patients, respectively. Failure (HB grade VI) was observed in 28.6% of patients. More than half of patients (62.5%) who had either a sural nerve cable graft or a faciohypoglossal transposition had a good outcome (HB grade III or IV). CONCLUSIONS: In the present series, 45% of patients had an HB grade of III or IV at long-term follow-up. The best outcome (HB grade III) was observed after cross-facial grafting with the sural nerve.
