Microendoscopic cervical anterior decompression and fusion (MECAF) offers a less invasive surgical option for cervical spine conditions. This technique showed significant reductions in common postoperative complications compared to traditional methods.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery

Background:

  • Traditional anterior cervical discectomy and fusion (ACDF) is associated with significant postoperative complications.
  • These complications, including airway obstruction and dysphagia, are particularly concerning in elderly patients and those with comorbidities.

Purpose of the Study:

  • To evaluate the safety and efficacy of a novel Microendoscopic Cervical Anterior Decompression and Fusion (MECAF) technique.
  • To compare MECAF outcomes with conventional ACDF, focusing on reducing postoperative complications.

Main Methods:

  • MECAF utilizes an 18-mm tubular retractor and a 25-degree endoscope for minimal soft tissue disruption.
  • The approach is along the lateral border of the omohyoid muscle, allowing en bloc retraction of the trachea and esophagus.
  • Procedures include endoscopic discectomy, cage insertion, and fixation with a self-locking plate.

Main Results:

  • Twenty patients (mean age 60.0 ± 15.3 years) underwent MECAF for various cervical conditions between 2021 and 2024.
  • The technique was successfully applied to both single-level and two-level surgeries.
  • Crucially, no patients experienced postoperative dyspnea, hoarseness, or dysphagia.

Conclusions:

  • MECAF is a safe and effective alternative to conventional ACDF for cervical spine pathologies.
  • The minimally invasive nature of MECAF significantly reduces the risk of common postoperative complications.
  • This technique holds promise for improving patient outcomes, especially in vulnerable populations.
