Absolute augmentation of the extremely atrophic mandible. (A modified technique)
Journal of Maxillofacial Surgery
|May 1, 1981
Summary
A new surgical technique reconstructs the atrophic mandible with reduced risk to the mandibular nerve. This method offers comparable bone resorption to the original technique, minimizing the need for additional procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
- Anatomy
Background:
- Atrophic mandible reconstruction presents challenges, including the risk of mandibular nerve injury.
- Existing techniques may require supplementary procedures like vestibuloplasty.
Purpose of the Study:
- To present a modified surgical technique for atrophic mandible reconstruction.
- To evaluate the safety and efficacy of this modified approach, focusing on nerve preservation and bone resorption.
Main Methods:
- A modified intra-extraoral or entirely extraoral approach mobilizes the caudal mandible.
- Bone grafting is performed between osteotomized mandibular fragments.
Main Results:
- Bone resorption is comparable to the original reconstruction method.
- The modified technique significantly reduces the risk of mandibular nerve lesions.
- Supplementary vestibuloplasty is infrequently required.
Conclusions:
- The modified technique offers a safer alternative for atrophic mandible reconstruction.
- It achieves comparable bone graft success while enhancing nerve protection.
- This approach may simplify the overall treatment process.
