Abstract OBJECT: The aim of this study was to determine the 10-year clinical outcomes of microendoscopic discectomy (MED), a surgical procedure for the treatment of lumbar disc herniation (LDH). METHODS: A total of 151 patients with LDH were treated with MED and followed postoperatively for up to 10 years. The modified MacNab criteria were used to examine the clinical outcomes. In a subset of patients (n = 107), the disc-height ratio was measured radiographically according to the Mochida's method. RESULTS: Based on the modified MacNab criteria, 120 (79\%) patients were rated as excellent, 20 (12.9\%) as good, 7 (4.6\%) as fair, and 5 (3.5\%) as poor. Only 5 patients (3.5\%) required additional surgery due to a recurrence of herniation. Other complications included intraoperative dural lacerations (5 patients) and spondylodiscitis (3 patients). Mochida's method showed an average disc-height ratio of 76.25\%. Approximately 67\% of the patients were able to maintain their primary occupations. CONCLUSION: The 10-year follow-up study showed that the long-term clinical outcomes of MED are satisfactory and better than those of the traditional discectomy procedure. The MED procedure is both feasible and efficacious for the treatment of LDH. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
