Information on treatment and surgery

Mandibular retrusion correction surgery

Mandibular retrusion refers to the backward retraction of the lower jaw than normal. This can make the mouth appear to be protruding and leave an impression of a dopey appearance. It can also lead to abnormal growth of the respiratory tract, causing problems such as snoring. The surgical process of correction mandibular retrusion may differ, depending on the nature of the problem. If the lower jaw is small or retruding without additional problems, the aesthetics can be improved through silicon expansion, cortex and other prosthetic methods at the tip of the chin. For a more fundamental solution, the tip of the chin can be cut and adjusted through genioplasty osteotomy. For mandibular retrusion with accompanying conditions such as malocclusion, adjustment on both the upper and lower jaw may be necessary.

Choosing the right hospital is crucial when planning for detailed surgical procedures.

Mandibular retrusion correction surgery requires precise aesthetic sense to consider the ideal facial proportion and ratio. When it is accompanied by other conditions, such as bimaxillary protrusion, orthognathic surgery must be completed additional to the retrusion correction surgery. The purpose of orthognathic surgery is not for aesthetics but to correct functional problems. Therefore, the patient must be careful and thorough in searching for the right hospital to carry out complex surgical methods through collaboration of oral and maxillofacial and orthodontic specialists.
