Hello, if you have a particularly serious deformity that may require orthognathic surgery, you can go to the Orthognathic Surgery of Tianjin Stomatological Hospital to consult Professor Chen Gang. If only one side of the nasal floor is depressed, nasal floor filling surgery can be done. I have been doing this operation for about 20 years. The best material is autogenous costal cartilage, and silica gel and swelling can also be used. MEDPOL can be fixed with titanium nails.
