Resection of accessory parotid gland tumors through a peroral approach with facial nerve monitoring.

摘要

Accessory parotid glands are an anatomic variation. Pathologic alterations, which occur in these tissues, are related to those found in the parotid gland. At this time, first-line therapy consists of total resection. In consideration of the delicate anatomy in this region, a careful approach through a lateral parotidectomy or a facelift incision is recommended. In this report, we give an account of a minimally invasive surgical alternative through a peroral approach with facial nerve monitoring. The histologically secured pleomorphic adenoma was completely removed. During surgery, a branch of the facial nerve was detected and secured with active nerve monitoring. We are confident that the peroral resection, supported by active and passive facial nerve monitoring, is a discussable alternative for well-selected tumors of accessory parotid glands.
