Impact Of Glossectomy In The Surgical Correction Of Tongue Source Class Ⅲ Skeletal Open Bite Deformity

Aim and objectiveTongue source skeletal dento-maxillofacial open bite deformities have shown high degree of post treatment relapse and degradation. This thesis is about the combination of glossectomy and surgical correction of dento-facial deformities. The outcome of such a combination was stability over a period of6years.MethodsThe surgical procedure consists of a bimaxiliary osteotomy and maxillary fragmentation if required. Reduction of the lower anterior facial height is achieved by maxillary rotation, closure of the gonial angle and genioplasty. The type of glossectomy performed is median-rhomboid hence reducing the volume while having a lingual proprioceptive action at the same time.Result and conclusionThe physiopathology of skeletal dento-maxillofacial Class Ⅲ open bite deformities is very complex in nature. Genetic factors dominate as the growth of the individual is compromised and lingual dysfunction affects the severity of the deformity. The combination of facial bone corrective surgery and glossectomy helps to reduce the risks of recurrence.
