Extracapsular dissection of the upper part of parotid gland benign tumor using a tragus edge combined retro⁃ auticular hairline incision approach

Abstract

Objective To investigate the clinical effect of dissection in the upper part of parotid gland benign tu⁃ mor using a tragus edge combined retroauticular hairline incision approach. Methods 20 cases of upper part of parot⁃ id gland benign tumor were resected using the tragus edge combined retroauticular hairline incision approach, the sur⁃ gery and cosmetic effect were analyzed. Results Parotid gland tumors were checked by CT before the operation and di⁃ agnosed by frozen section analysis during the operation. The tumors were successfully complete resected in all cases. There were no complications of Frey􀆳s syndrome, postoperative bleeding, and flap necrosis, 2 cases showed a tempo⁃ rary earlobe numbness, 1 case of temporary facial nerve paralysis and 1 case of salivary fistula. There were no tumor re⁃ currence after 24 ~ 48 months followed up. Surgical incision cosmetic effect is satisfactory. Conclusion The tragus edge combined retroauticular hairline incision is safe and feasible, with less complications for the upper part of parotid gland benign tumor resecetion.
