& ltp> First of all, in this part of the mandible, it is necessary to judge whether the mandible is bigger or the masseter muscle is bigger. If the mandibular angle of view is large due to the large masseter muscle, then the masseter muscle needs to be treated. Generally speaking, it can be improved by injecting face-lifting needle or performing masseter resection. The former can last for half a year to a year or so, and the latter can last longer. & lt/p & gt； & ltp style = \ " text-align:center \ " & gt； & ltimg src = \ "/uploadfile/image/20200226/1582678662335412.jpg \" alt = \ "Case of mandibular angle surgery in Fez Rheinland Hospital \" width = \ "660 \" height.

The effect of mandibular angle reduction surgery can be said to be very obvious, especially for the case of large mandible. A skilled doctor will design the scheme in combination with your whole face shape, and will make the lateral lines very smooth, which will greatly improve the overall situation. & lt/p & gt； & ltp style = \ " text-align:center \ " & gt； & ltimg src = \ "/uploadfile/image/2020226/158267862455048.png \" alt = \ "Comparison of mandibular angle before and after operation \" width = \ "362 \" height = \ "267 \" Height: 267px \ "/>; & lt/p & gt； The mandibular angle surgery of<p> generally involves osteotomy, bone grinding or long curve osteotomy, but no matter which method is adopted, you need to be reminded to find a qualified doctor. On the one hand, because the mandible has meridians, if the technique is not good, it is likely to touch the nerve line, causing incalculable consequences. On the other hand, experienced doctors can also ensure the effect. & lt/p & gt； & ltp style = \ " text-align:center \ " & gt； & ltimg src = \ "/uploadfile/image/2020226/1582678662623992.
