Abstract

OBJECTIVE
Anterior cervical microforaminotomy has become one of surgical options to treat cervical rad iculopathy. The goal of this study is to evaluate the effectiveness of anterior cervical microforaminotomy for single-level cervical radicular disease. METHODS: We performed a prospective review of radiological data and clinical records only in patients whom the patients met the inclusion criteria for this study. Among 53 patients who underwent anterior cervical microforaminotomy between June 2000 and May 2002, 36 patients were evaluated in this study.
RESULTS
Male to female rate was 2: 1 and mean age was 46.1(28-63) years. Compressive pathological lesions included disc herniation in 24 cases(66.7%), spondylosis 10 cases(27.8%), and a combined of the two in 2 cases(5.5%). Twenty eight patients(77.8%) experienced excellent results, six patients(16.7%) experienced good results, and two patients(5.5%) experienced fair results. No patient demonstrated a poor or unchanged outcome. All patients showed adequate decompression in their postoperative computed tomography or magnetic resonance images. There were no complications. Mean hospital stay was 3.9(3-12) days.
CONCLUSION
Patients treated with the anterior cervical microforaminotomy procedure for single-level cervical radicular disease have good outcomes. It appears to be a good alternative procedure for cervical radicular disease. But this procedure have complications such as vertebral artery injury. And long term follow up should be analyzed for instability or recurrence of disc herniation.
