Abstract:
Objective:To observe the clinical efficacy of immediate repair of extracranial branch defects in the facial nerve through transplantation of the great auricular nerve.Methods:A retrospective inclusion was carried out on 17 patients with extracranial branch defects of the facial nerve caused by parotid malignant tumors and neurogenic tumors in the Department of Stomatology of Xuzhou Central Hospital from June 2021 to January 2023, including 10 males and 7 females, with the age ranged from 28 to 68 (42.4±11.4) years old. All patients underwent immediate transplantation of the greater auricular nerve during the operation. The facial nerve function was evaluated according to the House-Brackmann (HB) facial paralysis grading standard at the last follow-up. Grade Ⅰ-Ⅲ was considered effective, and grade Ⅳ-Ⅵ was considered ineffective. The quality of life was evaluated using the physical function score (FDIP) and social function score (FDIS).Results:The follow-up time was 6-30 (18.3 ±6.6) months. The facial nerve function was classified as grade Ⅰ in four cases, grade Ⅱ in six cases, grade Ⅲ in four cases, and grade Ⅳ in three cases. This resulted in an effective rate of 14/17. The FDIP score at the final follow-up was (84.7 ±9.1) points, which was higher than the (54.1 ±20.6) points recorded at the immediate moment of repair ( P<0.001). In contrast, the FDIS score was (11.8 ±8.9) points, which was lower than the (57.5 ±11.7) points recorded at the immediate moment of repair ( P<0.001). Conclusion:The transplantation of the auricular great nerve can effectively enhance facial nerve function and improve the life quality in the immediate repair of defects in the extracranial branches of the facial nerve.
