Abstract
Surgery of the parotid gland is one of the most common operations in head and neck surgeries. Identification and functional preservation of the facial nerve is an important procedure in parotid gland surgeries, especially in the case of benign tumors. However, sometimes it is very difficult to identify the facial nerve in the case of recurrent tumors and tumors involving the parapharyngeal space, so-called dumbbell-type tumors. Here we report on the clinical usefulness of Nerve Integrity Monitoring System (NIM-Response 2.0, Medtronic, USA) to preserve the facial nerve function in three parotid gland tumor cases.
