Abstract

Objective: To evaluate the efficacy of hemilaminectomy as an approach to intradural tumors and to assess the risk of postoperative spinal instability.

Methods: This is a retrospective cohort study of 38 patients who underwent surgical resection of intradural tumors between November 2014 and March 2019. Clinical and radiologic data were documented in medical records, from which we obtained clinical data including age, gender, tumor etiology, lesion level, type of resection, and postoperative instability during follow-up.

Results: Schwannomas and meningiomas were the most commonly treated tumors. The lesion locations were as follows: 8 cervical (21%), 19 thoracic (50%), 10 lumbar (26%), and 1 sacral (3%). The mean follow-up time was 28 months. In all cases, hemilaminectomy allowed for the removal of the tumors without clinical or radiologic evidence of postoperative mechanical instability. Hemilaminectomy was primarily performed on 2 segments but was extended to up to 6 levels in some cases.

Conclusions: Unilateral hemilaminectomy is an effective technique that facilitates complete tumor removal with a low rate of postoperative instability in the operated segments.

单侧半椎板切除术作为脊髓肿瘤的主要治疗方法：对 38 例病例进行至少 24 个月随访的回顾性队列。

目的评估硬膜内肿瘤半椎板切除术的疗效，并评估术后脊柱不稳定的风险：这是一项回顾性队列研究，研究对象为2014年11月至2019年3月期间接受硬膜内肿瘤手术切除的38例患者。病历中记录了临床和放射学数据，我们从中获取了包括年龄、性别、肿瘤病因、病变水平、切除类型以及随访期间术后不稳定性在内的临床数据：结果：最常治疗的肿瘤是许旺瘤和脑膜瘤。病变部位如下8例颈椎肿瘤（21%）、19例胸椎肿瘤（50%）、10例腰椎肿瘤（26%）和1例骶椎肿瘤（3%）。平均随访时间为 28 个月。在所有病例中，半椎板切除术均能切除肿瘤，且无临床或放射学证据显示术后出现机械性不稳定。半椎板切除术主要在两个节段上进行，但在某些病例中可扩展至6个水平：结论：单侧半椎板切除术是一种有效的技术，有助于肿瘤的完全切除，且术后手术节段的不稳定性较低。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
