Vertebral corpectomy (vertebral body resection), partial or complete, for excision of intraspinal lesion, single segment; intradural, cervical

Vertebral corpectomy, as defined by CPT® Code 63304, is a surgical procedure that involves the resection of a vertebral body, which may be either partial or complete, specifically for the purpose of excising an intraspinal lesion. This procedure is performed on a single segment of the cervical spine and is characterized by the removal of not only the vertebral body but also the intervertebral discs located above and below the affected vertebra. The term "intraspinal" indicates that the lesion or tumor is situated within the spinal canal, while "intradural" specifies that it is located within or extending into the dura mater, the protective covering of the spinal cord. The approach to this procedure is typically anterior, requiring a careful incision in the front of the neck to access the cervical spine. The surgical technique necessitates meticulous dissection of soft tissues and muscles, as well as retraction of the trachea and esophagus to adequately expose the affected vertebral segment. The use of a surgical microscope is integral to the procedure, allowing for precise dissection and removal of the intervertebral discs and the vertebral body itself. Following the excision of the lesion, the dura may be incised if the lesion is found to be within or extending into it, necessitating careful dissection and removal of the tumor. Post-excision, the dura is repaired, and additional procedures such as bone grafting and spinal instrumentation may be performed to ensure stability and support for the spine. This comprehensive approach is essential for addressing the underlying pathology while maintaining the structural integrity of the cervical spine.
