Study Design:
Retrospective case-control study.
Objective:
To evaluate clinical outcomes of cervical microendoscopic laminotomy (CMEL) and segmental partial laminectomy (SPL) in patients with cervical spondylotic myelopathy (CSM).
Summary Of Background Data:
CSM often requires posterior decompression surgery. Conventional techniques such as laminoplasty and SPL are associated with significant challenges, including axial neck pain and reduced cervical range of motion (ROM). In contrast, CMEL, a minimally invasive approach, may offer superior outcomes. However, direct comparisons with SPL remain limited.
Methods:
We retrospectively analyzed 105 patients (58 with CMEL and 47 with SPL) who underwent posterior decompression surgery for CSM between 2003 and 2020. The evaluated outcomes included intraoperative parameters, postoperative clinical measures (e.g., Neck Disability Index (NDI), Japanese Orthopaedic Association (JOA) scores, including recovery rate and treatment satisfaction), radiographic assessments, and complication rates.
Results:
Compared with SPL, CMEL resulted in reduced blood loss, shorter hospital stay, less postoperative neck pain, ROM preservation, and fewer complications at 1 year postoperatively.
Conclusions:
CMEL is a minimally invasive alternative to SPL, providing reduced morbidity and improved outcomes. This is particularly true for aging populations that require functional preservation and quality of life improvement. By avoiding instruments such as interlaminar spacers and implants, CMEL can potentially reduce health care costs.
