Area of Science:

  • Craniomaxillofacial surgery
  • Medical device technology
  • Biomedical engineering

Background:

  • Complex facial trauma poses challenges to reconstructive surgeons due to disrupted facial buttresses.
  • Accurate 3D-printed models and virtual surgical planning are valuable but often have long turnaround times.
  • Industry-produced models may not be suitable for unplanned acute surgical settings.

Purpose of the Study:

  • To evaluate the efficacy and safety of using in-house 3D-printed models for treating facial fractures.
  • To assess the impact of these models on surgical decision-making and operative procedures.

Main Methods:

  • Retrospective analysis of 24 patients who received in-house 3D-printed models for facial fractures between January 2017 and August 2023.
  • Extraction of demographic data, fracture type, mechanism, complications, comorbidities, and operative time via chart review.
  • Data analysis performed using Microsoft Excel.

Main Results:

  • The average patient age was 24.5 years, with 62.5% of fractures caused by motor vehicle accidents.
  • The midface was the most commonly injured region (79.2%), and 33.3% of patients had panfacial fractures.
  • Average operative time was 268.3 minutes, with 12.5% minor and 6.25% major complications; 96% achieved satisfactory facial contour.

Conclusions:

  • In-house 3D printing provides timely anatomical models for facial fracture repair in acute settings.
  • These models assist surgical decision-making and facilitate procedures like pre-bending of plates.
  • The use of in-house 3D models enables safe and effective surgical treatment for complex facial trauma.
