[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.
