OBJECTIVE: in this study, the authors describe the surgical experience of 11 hourglass-shaped neurinomas at the C2 root, comparing the posterior and posterolateral approaches. METHODS: eleven patients with hourglass-shaped neurinoma of the cervical root of C2 were surgically treated. The approach used to remove the tumors was the posterior in seven patients and posterolateral in four patients. RESULTS: females predominated in this sample (n=6) and the mean age was 55.9±8.16 years. The time from onset of the symptoms to diagnosis was 16.3 months (±8,02 months). The mean surgical time was 180 minutes (±39.15) in the posterior approach and 192 minutes (±22.17) in the posterolateral approach (p=0.52). There was no statistically significant difference in the volume of intrasurgical bleeding among the groups (posterior approach: 70.71±16.93; posterolateral approach: 65.00±24.15; p=0.64). The tumor was completely resected in all patients. A complication occurred with the posterior access, which was the presence of a cerebrospinal fluid fistula, and it was necessary to reoperate, being the duramater reconstructed with fascia lata. CONCLUSION: the tumor was completely resected with both surgical approaches, but the posterior approach was preferable because the surgeon is more familiar with it.
