Summary
This study introduces "short ramus reconstruction" for mandible repair after hemimandibulectomy. This technique successfully prevents trismus and ankylosis, restoring function and aesthetics.
Area of Science:
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
- Biomaterials Science
Background:
- Mandibular reconstruction after hemimandibulectomy presents significant challenges, particularly regarding condylar reconstruction.
- Existing methods for condylar reconstruction often face controversies and potential complications like trismus and ankylosis.
Observation:
- The authors propose a novel technique: "short ramus reconstruction" aimed at reconstructing the mandible around the condylar base.
- This approach was applied to four patients undergoing hemimandibulectomy, utilizing fibula free flaps for reconstruction.
Findings:
- All four patients who underwent short ramus reconstruction experienced no post-operative trismus or ankylosis.
- The study reports successful outcomes including restored centric occlusion, improved masticatory function, and favorable aesthetics in all cases.
Implications:
- Short ramus reconstruction offers a simplified and effective solution for complex mandibular defects.
- This technique holds promise for improving functional and aesthetic results in patients requiring hemimandibulectomy and subsequent reconstruction.
