Facial Nerve Monitoring in Chronic Ear Surgery: Us Practice Patterns

OBJECTIVE : The use of intraoperative facial nerve monitoring (IOFNM) improves facial nerve outcomes in acoustic neuroma surgery, but the role of IOFNM in chronic ear surgery (CES) is poorly defined. This study was performed to identify IOFNM practice patterns in the United States for CES. METHODS : A 10-item survey was mailed to a random sample of 500 active members of the American Academy of Otolaryngology-Head and Neck Surgery. RESULTS : The overall response rate was 45.2%. Of the respondents, 75% had access to IOFNM, and of this group, 66% used IOFNM at least some of the time. Otolaryngologists trained in the 1990s (P < 0.0001), those in an academic setting (P = 0.02), and those who perform more otologic than other types of surgery (P = 0.004) were more likely to use IOFNM. Although most respondents had access to IOFNM, only 32% thought that IOFNM should be required for CES. CONCLUSIONS : The majority of otolaryngologists who perform CES have access to IOFNM and will use it at least some of the time. IOFNM use is especially prevalent in otolaryngologists who have trained recently and in more experienced otologic surgeons. However, there are strong feelings against requiring IOFNM for CES.
