摘　　要：目的 探讨腮腺手术中耳大神经后支保留的可行性、方法及临床价值。方法 我们对48例腮腺肿瘤患者，按常规隐蔽切口腮腺手术方法进行治疗，保留或不保留耳大神经后支。分别于术后10d及1、6、12个月进行随访，检测耳廓上部、耳垂、耳下区、耳前区和耳后区的触觉、痛觉，并观察其感觉变化情况。结果 48例中35例耳大神经后支保留，耳廓上部及耳后区感觉无减退。术后早期耳前、耳垂及耳下区感觉有不同程度的减退，以耳前区最明显，随着时间延长症状逐步好转，6个月时感觉接近正常。另13例耳大神经切断患者感觉减退症状更加明显，恢复时间延长。结论 腮腺手术中耳大神经后支保留是可行的，所采用的方法可靠，可减轻局部麻木感，提高患者术后早期生活质量，降低神经切断后产生局部永久性麻木的可能性。Objective To investigate the feasibility, technique and significance of preserving the posterior branch of the great auricular nerve in parotid surgery. Methods 48 cases with parotid tumor who underwent regular parotid surgery with cosmetic incision were included. The sensory testing was carried out in upper auricle, lobule, infra-auricular, pre-auricular and post-auricular region preoperatively and at 10 days, 1 month, 6 months and 12 months after operation. Results The posterior branch of the great auricular nerve was preserved in 35 out of 48 patients. There was no sensory loss in the upper auricle and post-auricular region. Early after operation, sensory disturbance was found in lobule, infra-auricular region, but significantly in pre-auricular region. The sensory disturbance was recovered slowly to nearly normal level at six months after operation. 13 cases with sacrifice of the nerve had a significantly higher sensory disturbance and a longer recovery time. Conclusions Preservation of the posterior branch of the great auricular nerve during pamtid surgery is technically feasible and can reduce the postoperative sensory disturbance and possible permanent sensory loss. It further helps to improve the quality of life early after operation.
