[Utilization of functional surgery in benign parotid tumor of superficial lobe].

OBJECTIVE: To investigate the utilization of functional surgery in benign parotid tumor of superficial lobe. METHOD: Conventional parotidectomy were modified in the following aspects: incision, preservation of great auricular nerve, local facial nerve dissection, partial superficial parotidectomy and repairing of sunken deformity. The post-operative recurrence incidence, functional outcomes and complications of 21 patients with benign parotid tumor of superficial lobe undergoing functional surgery were analyzed retrospectively. RESULT: No recurrence of tumor was found in follow-ups. No obvious scar and sunken deformity was found. The area with abnormal sensory around the auricle was smaller compared with those whose great auricular nerve had not been preserved. Post-operative transient facial paralysis was observed in 4 cases and all recovered in 3 months. One case complained about Frey's syndrome. Salivary leakage was found on 1 case. CONCLUSION: Compared with conventional surgery, functional surgery for benign parotid tumor of superficial lobe may improve cosmetic, sensory, salivary function, facial nerve function and quality of life without raising post-operative recurrence.
