摘要
Parotid gland tumors are common and mostly benign.The main treatment is surgical excision.The conventional surgical procedure,progressing from shallow to deep tissue,usually comprises three steps:first,exposing of superficial gland surface by raising a skin flap;second,approaching the tumor via destruction of the overlying gland tissue;third,tumor removal(e.g.,by extracapsular dissection[ECD]).The surgical complications may include iatrogenic sialocele or fistula secondary to extensive injury of gland tissue,or facial palsy caused by contact with the facial nerve branches intraoperatively.
