Intraoperative navigation with Kolibri significantly reduced orbital reconstruction complications compared to traditional methods. This technology improves surgical precision and patient outcomes in orbital trauma cases.

Area of Science:

Ophthalmology
Neurosurgery
Medical Technology

Background:

Orbital reconstruction is a complex surgical procedure often relying on surgeon experience due to a lack of objective assessment methods.
Intraoperative navigation systems offer potential for increased precision in complex surgical procedures.

Purpose of the Study:

To evaluate the efficacy of the Kolibri intraoperative navigation device in improving outcomes for orbital trauma reconstruction surgery.

Main Methods:

A prospective matched control trial involving 58 patients with orbital trauma who underwent surgery.
Twenty-nine patients were operated on using the Kolibri navigation system, while 29 served as a control group.
Postoperative outcomes were assessed subjectively (ophthalmologic features) and objectively (comparison of reconstructed vs. planned orbital floor using CT scans).

Published on: October 17, 2025

Main Results:

Fewer postoperative ophthalmologic complications were observed in the navigation group at 1, 3, 6, and 12 months (e.g., 41% vs. 72% at 1 month).
Objective measurements showed the reconstructed orbital floor was closer to the planned position in the navigation group (3.24 mm difference).
Statistical significance was noted for reduced complications (P < 0.05) and improved accuracy (P = 0.001).

Conclusions:

Intraoperative navigation with the Kolibri system minimizes postoperative complications in orbital reconstruction.
The technology aids surgeons in planning, execution, and postoperative assessment, potentially reducing the need for revision surgeries.
Navigation systems enhance accuracy and improve patient outcomes in managing orbital trauma.
