Summary
Three-dimensional (3D) printing surgical guides precisely correct complex midfacial deformities. This novel method significantly improves patient outcomes and offers a valuable solution for challenging reconstructive surgeries.
Area of Science:
- Craniofacial surgery
- Medical imaging
- Biomedical engineering
Background:
- Intraoperative computed tomography and image-guided navigation offer advantages for midfacial post-traumatic deformity correction.
- Current navigation methods do not consistently yield satisfactory results for complex deformities.
Purpose of the Study:
- To describe a novel method for precise correction of complex midfacial post-traumatic deformities.
- To evaluate the efficacy of three-dimensional (3D) printing customized surgical guides.
Main Methods:
- Ten patients with midfacial post-traumatic deformities were included.
- 3D-printed cutting guides and customized titanium plates were designed using preoperative virtual planning.
- Osteotomy and repositioning were guided by the customized guides and confirmed with intraoperative navigation.
Main Results:
- The average deviation between virtual plans and postoperative results was under 1.5 mm.
- Postoperative clinical examinations showed significant improvement in function and aesthetics.
- Patient symptoms were alleviated during 3- to 6-month follow-up.
Conclusions:
- 3D-printed customized surgical guides accurately transfer virtual surgical plans to patients.
- This technique is an ideal and valuable option for complex midfacial reconstructive procedures.
