Abstract

Objective: To investigate the clinical manifestation and management strategy of intraparotid facial nerve schwannoma. Methods: The clinical data of 12 patients with parotid schwannoma treated in Henan Cancer Hospital from January 2009 to January 2019 were analyzed retrospectively, including 5 males and 7 females, aged from 23 to 72 years. All the 12 patients complained of a mass in the parotid region, of whom 4 patients had local discomfort and pain, and 6 patients had varying degrees of pain during palpation. Ultrasound examination showed solid mass in parotid region in 8 cases and mixed mass in 4 cases. The treatment methods, the relationship between tumor and facial nerve, the modes of treatments and the nerve functions before and after operation were analyzed and summarized with House-Brackmann grade.
