ObjectiveTo determine the benefit to postoperative facial function of intraoperative facial nerve monitoring (IFNM) during recurrent pleomorphic adenoma (RPA) parotid surgery. Study DesignCohort study with planned data collection. SettingChinese PLA General Hospital. Subjects and MethodsFifty-eight RPA parotidectomies were performed between 2004 and 2012. Recurrence was confirmed by histopathologic examination. None of the patients had preoperative facial palsy. Electromyography-based IFNM was used in 28 patients; 30 patients were unmonitored. The durations of surgery and the severity of postoperative facial nerve palsy were compared between the 2 groups. ResultsThere were no significant differences between the 2 groups in the incidence of immediate or permanent facial paralysis after RPA parotidectomy (P =. 95 and P =. 36, respectively). However, the differences in the average duration of surgery and the severity of postoperative facial nerve palsy after total parotidectomy or wide resection were significant (P P =. 01, respectively). In contrast, these differences were not significant after superficial parotidectomies (P =. 43 and P =. 49, respectively). The average recovery time of temporary facial nerve paralysis was significantly shorter in the monitored group compared with the unmonitored group, independent of surgical technique (P <. 01). ConclusionThe use of IFNM during total or wide resection RPA parotidectomy reduced the duration of surgery and the incidence of postoperative facial paralysis and enhanced recovery. However, there was little impact on facial nerve outcomes when IFNM was used during superficial RPA parotidectomy.
