Exoscope for Upper Extremity Peripheral Nerve Surgery: Revision Carpal Tunnel Release With Epineurolysis and Hypothenar Fat Flap

The exoscope is a high-resolution three-dimensional external microscope that allows the surgeon to perform delicate dissection in multiple regions of the body. The exoscope was originally used for intracranial and spine surgery. In this article, we describe its novel use in upper extremity peripheral nerve decompression surgery after recurrent carpal tunnel syndrome. This surgery is typically performed under the microscope, which allows precise microsurgical dissection to distinguish scar tissue from healthy nerve fascicles. Our case report highlights a 70-year-old man with recurrent carpal tunnel syndrome who underwent revision carpal tunnel surgery with epineurolysis and hypothenar fat flap. The ergonomic benefits of using the exoscope for microsurgery are described, along with intraoperative photos. Adequate symptom resolution was achieved.
