Area of Science:

Plastic Surgery
Biomedical Engineering
Medical Device Technology

Background:

Crooked nose correction (rhinoplasty) requires high surgical precision.
Existing methods for nasal osteotomy can have variable accuracy.
3D printing offers potential for creating patient-specific surgical tools.

Purpose of the Study:

To evaluate the feasibility and accuracy of a novel 3D-printed surgical guide for nasal osteotomy.
To assess patient-reported outcomes following crooked nose correction using the 3D-printed guide.

Main Methods:

A customized 3D-printed surgical guide was designed and utilized for nasal osteotomy in ten patients.
Surgical accuracy was quantified by measuring the deviation of the osteotomy from the planned path.
Patient-reported outcomes were assessed using the Rhinoplasty Health Inventory and Nasal Outcomes (RHINO) questionnaire.

Main Results:

The 3D-printed surgical guides enabled highly accurate osteotomies, with a mean deviation of only 0.48 mm from the planned surgical path.
Patients reported significant improvements in outcomes as measured by the RHINO questionnaire.
The study demonstrated successful application in a small cohort, indicating feasibility.

Conclusions:

Customized 3D-printed surgical guides represent a promising advancement for improving precision in crooked nose correction.
This technology has the potential to enhance surgical predictability, minimize complications, and ensure consistent results.
The findings suggest that 3D-printed guides could be particularly beneficial for surgeons with less experience.
