Genioplasty corrects chin deformities but can lead to segment displacement, especially with trauma. This study details two rare cases of post-genioplasty segment displacement following facial trauma.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Facial Aesthetics
Background:
- Facial aesthetics rely on balanced proportions, with the chin significantly impacting the lower facial third.
- Surgical correction of chin deformities involves alloplastic implants or genioplasty (mental basilar ostectomy).
- Genioplasty offers versatility for 3D chin deformities and fewer complications than implants, though risks like nerve damage and instability exist.
Observation:
- This study examines two unique cases of osteotomized segment displacement after genioplasty.
- The displacement occurred in conjunction with facial trauma during the postoperative orthognathic surgery phase.
- These specific complications following genioplasty and trauma have not been previously documented in medical literature.
Findings:
- The primary finding is the rare complication of osteotomized segment displacement after genioplasty.
- This displacement was exacerbated by subsequent facial trauma during the orthognathic surgery period.
- The presented cases highlight unusual postoperative outcomes not previously reported.
Implications:
- These findings underscore the importance of careful postoperative management and monitoring after genioplasty, particularly in patients with potential for trauma.
- Understanding these rare complications can inform surgical planning and patient selection for genioplasty.
- Further research may be warranted to explore the biomechanics and risk factors associated with segment displacement in complex cases.
