Abstract
Aims
The current manuscript explores the viability of reverse sagittal split osteotomy technique for correction of ankylotic cases with post gap arthroplasty mandibular retrognathia to achieve socially acceptable esthetic results.
Method
Reverse sagittal split osteotomy which was introduced by Collins et al in 1983 was performed with certain modifications on two cases to correct mandibular hypoplasia in post gap arthroplasty cases. The paper also highlights intraoral as well as extraoral approach for performing the osteotomy along with better management of bad split under direct vision.
Result
It was observed that the reverse sagittal split technique for advancement of mandible in cases of tmj ankylosis-induced dentofacial deformity provided better proximal control, reduced chances of bad split, greater range of advancement (11-14 mm) with esthetically acceptable results. The osteotomy cuts on lateral surface of mandible make the procedure effectively easier and quicker with better control over proximal segment and management under direct vision.
Conclusion
When Distraction Osteogenesis and conventional orthognathic is not a choice in management of dentofacial deformity of post-release ankylosis cases due to the poor proximal control and concern over bad split, reverse sagittal split can be an appropriate choice to manage these deformities without any donor site morbidity.
