© 2010 John Wiley & Sons A/S. Objective – To determine surgical mortality, incidence of surgery‐related neurological deterioration and incidence of postoperative infection or hematoma requiring reoperation in a consecutive series of 318 patients surgically treated with laminectomy or laminoplasty for cervical spondylotic myelopathy (CSM). Materials and methods – This is a retrospective study of 318 consecutive patients treated with laminectomy or laminoplasty for CSM at Oslo University Hospital in the time period 2003–2008. The defined neurosurgical catchment area for OUS is the southeast region of Norway with 2.7 mill inhabitants. The patient charts were systematically reviewed, focusing primarily on operative notes, postoperative (po) complications, such as po deterioration of neurological function, po hematoma and po infection and neurological function at most recent follow‐up. Results – The mean age was 64 years (range 29–90 years). Laminectomy was performed in 310/318 (97.5%) and laminoplasty in 8/318 (2.5%) of the patients. The incidence of laminectomy/laminoplasty for CSM was 2.0/100,000 inhabitants per year. The surgical mortality was 0%, and 37 (11.6%) patients had a deterioration of neurological function in the immediate postoperative period. Four (1.3%) patients were reoperated because of po hematoma. We found a statistically significant association between po hematoma and previous posterior neck surgery and American Association of Anaesthetists (ASA) score. Five (1.6%) patients were reoperated because of postoperative infection. Univariate logistic regression analysis showed a statistically significant association between po infection and the number of levels decompressed. Conclusions – The incidence of laminectomy/laminoplasty for CSM is 2.0/100,000 inhabitants per year. Surgical mortality, postoperative hematoma and postoperative infection are rare complications of laminectomy/laminoplasty for CSM. Neurological deterioration is not an uncommon complication after posterior decompression for CSM.
