OBJECTIVE: To assess the use of intraoperative neurophysiologic monitoring (MNIO) by Brazilian spine surgeons. METHOD: Data collection was conducted through a questionnaire applied to 307 spine surgeons during the 11º Congresso de Cirurgia Espinhal e XIII Congresso da Sociedade Brasileira de Coluna. RESULTS: Of the surgeons interviewed, 42% are neurosurgeons and 58% are orthopedists. Most of them (72.3%) reported that have already used MNIO, however, only 29.6% use this procedure routinely. 39% of them are orthopedists. Among neurosurgeons, most (84%) reported not using MNIO routinely. In cases of deformity, 85.7% of the professionals said they use routinely the MNIO. 68. 1% answered that did not have easy access to MNIO, of which 10% work in the Midwest region of the country and 11% in the Northeast. Of those who reported ease access to the procedure, 77% work in Southeast. The average age of the participants was 41.9 years, with a median of 39.0, standard deviation of 11.3 and a confidence interval of 1.3. For the medical training period, the average was 17.8 years, with a median of 14.0 and a standard deviation of 1.2. Regarding the length of practice in spinal surgery it was found that 56.3% are under 10 years of practice. CONCLUSION: The majority of spine surgeons have already used MNIO, yet few use it as a routine. The Southeast region is where there is easier access to MNIO, unlike the Midwest and Northeast.
