Somatosensory evoked potential monitoring during endoscopic endonasal approach to skull base surgery: analysis of observed changes.

abstract：BACKGROUND:The incidence of symptomatic adjacent segment disease (ASD) after anterior cervical diskectomy and fusion (ACDF) was reported as 2.9%/y in a previous cohort of 374 patients. Few other data corroborate the incidence and natural history of ASD. OBJECTIVE:To calculate the incidence of ASD after ACDF that requi...
