Abstract: 【Abstract】 Objective To evaluate the clinical effect of the minimal preauricular and retroauricular incisions in parotidectomy of benign tumor. Methods Thirty patients with benign parotid tumor were reviewed in this study. Parotidectomy was designed as follows: a minimal preauricular and retroauricular incision was used, partial-superficial parotideceomy was applied, the preservation of facial nerve as well as great auricular nerve was carried out in parotidectomy of benign tumor. Follow-up study for3 to 24 months included the cosmetic effect of this incision and the clinical effect. Results The minimal preauricular and retroauricular incision healed uneventfully in all patients without salivary fistulae. After a follow-up, all the patients showed results with no obvious scar and sunken deformity left in face and parotid region. Two patients had temporary facial paralysis but recovered in 3 months with the treatment of cortical hormone and neurotrophic drugs. Four patients felt numb in ear lobe and the symptom was disappeared in 3-10 months post-operation. No patient had presented with clinical Frey's syndrome, as well as no tumor recurrence. Conclusion This minimal preauricular and retroauricular incisionsis a feasible technique, providing excellent cosmetic outcome in the treatment of benign parotid neoplasms.
