Area of Science:

Ophthalmology and Robotic Surgery
Minimally Invasive Surgical Techniques

Background:

Graves' ophthalmopathy can cause disfigurement and vision impairment due to orbital tissue expansion.
Orbital fat decompression is a surgical option to alleviate these symptoms, but traditional methods carry risks.

Purpose of the Study:

To evaluate the safety and feasibility of robot-assisted orbital fat decompression surgery.
To assess the efficacy of this robotic approach in reducing exophthalmos and improving patient quality of life.

Main Methods:

Ten patients (18 eyes) with Graves' ophthalmopathy underwent robot-assisted orbital fat decompression using the da Vinci Xi surgical system.
Key metrics including operative time, blood loss, complications, exophthalmos reduction, and Graves' Orbitopathy Quality of Life (GO-QoL) scores were recorded.
Preoperative and 3-month postoperative measurements were compared to evaluate surgical outcomes.

Main Results:

All procedures were completed successfully with a mean operative time of 124.3 minutes and minimal blood loss (mean 17.8 mL).
No intraoperative or postoperative complications were reported.
Significant reductions in exophthalmos (P < 0.0001) and improvements in GO-QoL scores for both visual function and appearance (P = 0.027) were observed.

Conclusions:

The da Vinci Xi system offers the necessary stability, dexterity, and visualization for safe and effective robot-assisted orbital fat decompression.
This study presents the first in-human results demonstrating the safety and effectiveness of robot-assisted orbital fat decompression for Graves' ophthalmopathy.
