Aim:To analyse retrospectively our experience and challenges of unilateral hemilaminectomy in IDEM tumors.Material and Methods:This study include 28 patients of IDEM tumors, operated by unilateral hemilaminectomy during the period from 2011 to 2016. The pre-operative clinico-radiological data, intra-operative findings and post-operative outcomes, all were analysed by entering the data in software.Results:The mean age of the patients was 49.14±12.23 years, and the average duration of symptoms was 11.82 weeks. The tumor distribution in the spine was as follows: cervical spine (14.2%), cervicodorsal spine (3.6%), dorsal spine (39.3%), dorsolu mbar spine (10.7%), and lumbar spine (32.1%). Twenty patients (71%) underwent two-level laminectomies, and three-level laminectomies were performed on eight patients (29%). The mean operative time was 4 hours and 40 minutes. Conclusion:Unilateral hemilaminectomy is a safe, minimally invasive procedure for the excision of IDEM tumors. Beginners may face difficulties with this procedure and should ideally take more time than with a conventional total laminectomy because of the narrow operating corridor. As more experience is gained, this procedure will become easier in selected cases.
