Soft tissue changes with combined mandibular setback and advancement genioplasty
Journal of Oral Surgery (American Dental Association : 1965)
|July 1, 1981
Summary
This study on advancement genioplasty found a 1:1 ratio of soft tissue change to chin advancement in patients with mandibular prognathism. The modified technique preserved soft tissue for predictable aesthetic outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Aesthetic Surgery
Background:
- Mandibular prognathism presents aesthetic challenges, including a flattened labiomental sulcus and deficient chin.
- Surgical correction often involves complex procedures to improve facial harmony.
Purpose of the Study:
- To evaluate soft tissue changes following a modified advancement genioplasty combined with mandibular setback.
- To determine the predictability of soft tissue response to genial segment repositioning.
Main Methods:
- A modified advancement genioplasty technique was employed, prioritizing soft tissue preservation.
- Six patients with specific facial characteristics underwent the combined surgical procedure.
Main Results:
- The modified genioplasty technique consistently achieved a 1:1 ratio between soft tissue displacement and bony advancement.
- This indicates predictable soft tissue behavior in response to the surgical manipulation.
Conclusions:
- The modified advancement genioplasty technique offers predictable soft tissue changes in patients with mandibular prognathism.
- This approach can effectively address aesthetic concerns related to chin deficiency and lower lip prominence.
