DOI : 10.5137/1019-5149.JTN.29896-20.2 AIM: To perform three-level decompression with a single-level corpectomy by modifying the fusion with anterior cervical corpectomy (ACC-F) method on a cadaver.

MATERIAL and METHODS: The anterior cervical region of four whole-head cadavers was dissected. The corpectomy was performed under a surgical microscope with a MT4-20+ ultrasonic bone dissector (UBD) tip. Superior and inferior decompression were conducted and viewed with a 70° neuroendoscope using two types (vertically and horizontally oriented) of specially designed 23 mm-long, 90°-angled UBD tips.

RESULTS: After neck dissection and the removal of the thyroid and cricoid cartilages, C5 corpectomy and adjacent-level discectomies were performed. Following discectomy and corpectomy, superior and inferior decompression were conducted with specially designed UBD tips and viewed with a 70° neuroendoscope. A three-level anterior cervical decompression was provided with a single-level corpectomy.

CONCLUSION: This study demonstrated that two more level decompression is possible with a single-level corpectomy in the cervical region using the new technique. Keywords : Cervical, Spondylosis, Posterior longitudinal ligament ossification, Minimally invasive approach, Multi-level decompression
