Who is more important, mandibular margin resection or lateral plate resection?
Jun Guo, Department of Plastic Surgery, Yangzhou First People's Hospital: Unless the patient is a simple mandibular ectropion, it is rare to split only the outer plate. Therefore, it is not recommended to simply split the outer plate, because it can reduce the width of the face, but the mandibular lines on the side will be blurred, making people look less delicate. In clinic, the technique of chopping the external board is much easier than cutting the mandibular margin, and a small amount of mandibular angle can be cut off while chopping the external board. Because it does not involve the resection of the mandibular angle margin, many doctors who are new to plastic surgery often regard it as an experimental stage of mandibular angle surgery. Because although the patient did not become more beautiful after surgery, the width of the lower part was narrowed to some extent. This surgical method must have certain applicable conditions, which must be cautious. The patient was satisfied with the split operation of the outer plate only recently, because the width of the face has been reduced, but with the extension of time, the defects of facial lines are gradually exposed, so the long-term effect is generally unsatisfactory. Removal of the mandibular margin can make the mandibular line clear and make girls feel more delicate, but it often does not change the width of the front face too much. Therefore, on the basis of removing mandibular margin and mandibular angle, the two methods can be harmonious and unified. In clinical work, some doctors are used to grinding the external plate first, and then to the mandibular angle (because grinding the external plate is conducive to the exposure of the field of vision and can see more clearly). Therefore, after the mandibular angle is removed, the opportunity to split the outer plate has been lost. Therefore, we can only use the operation of grinding the outer plate and cutting the mandibular angle. In fact, it is also a helpless choice.
