Abstract

Objective

The present study was designed to evaluate the use of inverted-L osteotomy of ramus combined with iliac bone graft for the treatment of mandibular hypoplasia inadult patients.

Methods

Intraoral or extraoralinverted-L osteotomy of ramus and iliac crest bone grafting were used for the treatment of mandibular hypoplasia in 11 adult patients (aged 19 to 29 years) from 2010 to 2016. Data were collected from the patients' records, photographs andradiographs.

Results

The height and width of the mandibular ramus were significantly augmented by inverted-L osteotomy and iliac crest bone grafting with minimal complications in all patients, resulting in remarkable improvements both in facial appearance and occlusion.

Conclusions

Our preliminary results showed that the inverted-L osteotomy of ramus and iliac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular hypoplasia.
