Telemicrosurgery (TMS) and conventional microsurgery (CMS) were compared for learning microsurgical anastomosis. While TMS offers tremor elimination and enhanced vision, CMS demonstrated a faster learning curve due to tactile feedback, crucial for untrained surgeons.

Area of Science:

Surgical Techniques
Robotic Surgery
Microsurgery

Background:

Conventional microsurgery (CMS) learning is challenged by physiological tremor.
Telemicrosurgery (TMS) theoretically simplifies procedures by eliminating tremor but lacks tactile feedback.

Purpose of the Study:

To compare the learning curve of microsurgical anastomosis between TMS and CMS.
To evaluate the feasibility of TMS for surgeons without prior experience.

Main Methods:

Thirty earthworm anastomoses were performed using 10/0 nylon sutures.
Fifteen anastomoses utilized CMS under an operating microscope, and 15 used TMS via a Da Vinci S® robot.
Performance was evaluated by suture and anastomosis completion times, and anastomosis integrity (permeability/watertightness).

The Microscopic Transcanal Approach in Stapes Surgery Revisited

Published on: February 16, 2022

Main Results:

The average time per suture was 296 seconds for CMS and 529 seconds for TMS.
Anastomosis integrity was 86.66% in both groups.
Learning was faster with CMS than TMS, with tactile feedback identified as a limiting factor in TMS for novice surgeons.

Conclusions:

CMS presents a faster learning curve than TMS for microsurgical anastomosis in untrained surgeons.
Despite the learning curve, TMS offers significant advantages including 3D vision, tremor elimination, and motion scaling.
