Square Jaw Surgery and V-Line Square Jaw Surgery

When the contour of the lower jaw is angular and broad, you may consider square jaw surgery or V-line square jaw surgery.

Square jaw surgery generally refers to surgery that refines the contour of the lower jaw, from the angular area below the earlobe to the area near the lips.

 

If, during square jaw surgery, the contour of the lower jaw is refined too steeply in a straight line as shown in the illustration below, there is a risk that the contour may become overly artificial and unnatural.

 

Therefore, to create a curved contour of the lower jaw, it is helpful to refine it carefully in several steps, as shown below.

V-line square jaw surgery refers to surgery that sharpens the contour of the lower jaw overall, including the front chin.

In V-line square jaw surgery, the method used to refine the contour of the front chin varies depending on the face shape, and several methods like the following are applied. 

                                  

                                   

                                                                        Rotational shaving    

                                   

                                                                         T osteotomy

    If the chin length before surgery is neither long nor short, the chin can be shaped into a V-line using rotational shaving or the T osteotomy method.                                               

If the chin length before surgery is short - some of the bone refined from the surrounding area can be inserted into the front chin to extend its length, creating a V-line contour that connects smoothly with the surrounding area.                                                

                                                 

If the chin length before surgery is long - the chin length can be reduced through a sandwich osteotomy, while the contour connecting to the surrounding area can be shaped into a V-line.       

 

 

 

However, it is reasonable to apply each method appropriately depending on the conditions, and because each method has its own advantages, disadvantages, and limitations, it is not appropriate to use only one method indiscriminately.
