A Novel Use of the Exoscope for In-Vivo Microvascular Free Flaps

Area of Science:

• Microsurgery
• Surgical Technology
• Head and Neck Reconstruction

Background:

• The operating microscope has been the standard for microvascular surgery.
• Innovations in camera and display technology offer new tools for surgeons.
• Head and neck free flap reconstruction requires precise microvascular anastomosis.

Purpose of the Study:

• To evaluate the use of an exoscope for microvascular anastomosis.
• To compare the exoscope with the operating microscope in head and neck free flap reconstruction.
• To assess the advantages and disadvantages of exoscope use.

Main Methods:

• A retrospective analysis of 46 head and neck free flap reconstructions.
• Utilized an exoscope system with cameras on a flexible arm and a high-definition monitor.
• Compared exoscope performance against the traditional operating microscope.

Main Results:

• The exoscope was successfully used for microvascular anastomosis in all 46 cases.
• Surgeon comfort was noted as an advantage with the exoscope.
• Improved viewing angulation was another benefit reported by users.
• The exoscope proved to be a viable substitute for the operating microscope.

Conclusions:

• The exoscope is a feasible and effective tool for microvascular anastomosis in head and neck free flap surgery.
• Exoscope use offers potential benefits in surgeon ergonomics and visualization.
• Further research may explore broader applications and long-term outcomes.
