Lantern Jaw Correction
Protruding chin normally refers to the case of prominent lower jaw or long face, and it is divided into 2 major types based on which surgical method is preferred.
Typical Lantern Jaw Types
01
Protruding Chin Caused by Mandibular Protrusion
It is the symptom of entire lower jaw structure being prominent, rather than overgrowth of jaw bone. Two jaw surgery is recommended in such case to repair the alignment of molars of upper and lower jaws.
Surgical Method : Two Jaw Surgery
Two Jaw Surgery involves osteotomy on both upper jaw (maxilla) and lower jaw (mandible) to reposition them. Rough edges are smoothened out and bones are reattached after being repositioned. Once protruded bone is corrected, fixation is applied not to make the operated bone further moves.
