우측 이하선에 발생한 혼합종의 외과적 치험례

Abstract

The patient presenting with a mass lesion of the parotid is frequently found to have mixed tumors of salivary tissue origin. The lesion is more common in females and inpatients of the median age of 50 years old. Recurrence of the mixed tumor is 0 to 50%. So avoidance of fragmentation or rupture of the tumor and removal of wide marginal tissue along with the tumor during surgery should be emphasized. From the surgical point of view. because of operative risk of facial nerve damage, the most important anatomical structure in relation to the parotid gland is seventh cranial nerve. Of the case reported here, benign mixed tumor occurred in the right parotid region of a 40 year old female patient, treated with surgical excision with preservation of 7th cranial nerve. Eight months follow-up evaluation showed good prognosis, and no evidance of complication and/on recurrence.
