Ultrasonic osteotome versus high-speed burr in channel-assisted cervical key hole technology: a clinical retrospective study

The ultrasonic osteotome enhances surgical efficiency, minimizes intraoperative bleeding, and accelerates postoperative recovery in cervical endoscopic keyhole procedures, with a favorable safety profile compared with the traditional high-speed drill. Although both instruments yield similar clinical outcomes, the superior precision and hemostatic control of the ultrasonic osteotome support its broader application in spinal surgery. Further multicenter, prospective studies are warranted to validate its clinical utility and long-term safety.
