Minimally invasive resection of cervical schwannoma (C1-C2 level) using tubular retractors.

Abstract

Cervical schwannoma excision usually involves laminectomy and violation of the facet joints that necessitates the need for fusion with consequent loss of cervical mobility. The authors present the first video demonstration of an excision of the cervical schwannoma at the C1-2 level using minimally invasive spine tubular retractors, which allows direct access to the lesion and prevents the need for any bony removal. It also preserves the paraspinal muscles, which are important for spinal stability, especially at the C2 level. Special attention is given to incision planning and preoperative image analysis for preventing injury to critical neurovascular structures at this level.
