Abstract：
Background/Objectives: Expansive open-door laminoplasty results in favorable clinical outcomes for cervical myelopathy. However, some postoperative complications associated with surgical invasiveness, such as axial neck pain and kyphosis, have not been resolved. The use of an exoscope, which is a recently introduced novel magnification tool, allows for traditional open-door laminoplasty with minimal invasiveness. Therefore, we propose the use of exoscopic minimally invasive open-door laminoplasty (exLAP) and present its clinical outcomes during the acute postoperative period. Methods: A total of 28 patients who underwent open-door laminoplasty at C3-C6 were reviewed. Of these patients, 17 underwent exLAP (group M) and 11 underwent conventional Hirabayashi open-door laminoplasty (group H). Outcomes were evaluated using numerical rating scale (NRS) scores for neck pain and the frequency of oral analgesic use from postoperative day 1 to 7. Results: The NRS score for neck pain was significantly lower for patients in group M than for those in group H. Conclusions: ExLAP is a novel, practical, and minimally invasive surgical technique that may alleviate the postoperative axial pain of patients with cervical myelopathy.
摘要：
背景/目的：展开式开门式椎管成形术对脊髓型颈椎病具有良好的临床疗效。然而,一些与手术侵袭相关的术后并发症，如轴性颈部疼痛和后凸，尚未解决。使用外镜，这是最近推出的一种新颖的放大工具，允许传统的开门椎板成形术与最小的侵入性。因此,我们建议使用外腹腔镜微创椎管成形术(exLAP),并介绍其在术后急性期的临床结果.方法：回顾性分析28例C3-C6椎板开放成形术患者的临床资料。在这些病人中,17例接受exLAP（M组），11例接受常规平林开门椎板成形术（H组）。从术后第1天到第7天，使用颈部疼痛和口服镇痛药使用频率的数字评定量表（NRS）评分评估结果。结果:M组患者颈部疼痛的NRS评分明显低于H组。结论:ExLAP是一种新的,实用,和微创手术技术可以减轻脊髓型颈椎病患者的术后轴性疼痛。
