What is a lantern jaw? (Double Jaw Surgery)




What is a lantern jaw?

A lantern jaw is a case where the lower jaw is longer than the upper jaw, and the lower jaw is protruded forward when seen from the side. In general, if the issue is confined to teeth without there being any issue on the bone structure, it can be treated by orthodontics only. However, if there is an issue on the bone structure, double jaw surgery becomes a must.




Lantern jaw surgical method by type

The appropriate surgical method to treat a lantern jaw varies depending on the symptoms. There is lower jaw surgery that treats the lower jaw only, whereas there is double jaw surgery that treats both the upper and the lower jaws. At EU Oral & Maxillofacial Surgery, the surgical method varies based on our precise diagnosis, and we offer the most appropriate surgical method to each of our patients. When performing lantern jaw surgery, we at EU Oral & Maxillofacial Surgery chooses from either the Intraoral Vertical Ramus Osteotomy (IVRO) or the Sagittal Split Ramus Osteotomy (SSRO) depending on the circumstances of the patient’s lantern jaw.
