采用下颌升支纵劈术来矫正各种下颌畸形,在以往的文献中已有详细的记载。许多口腔外科医师看来喜欢采用Dal Pont改良的Trauner&Obwegeser(1975)手术式。它的主要优点是:整个手术在口内进行,因而避免产生任何外部瘢痕;可作前后方适度移动,从而使两骨折面之间有良好的骨接触,便于骨愈合。该手术方法除上述优点外,也有许多合并症。1972年Behrman调查了大约600例病人,发现最常见的合并症是:复发、出血、伤及下颌神经、水肿、升支碎裂、
The use of mandibular ascending longitudinal chiseling to correct a variety of mandibular deformities, in the literature have been documented in detail. Many oral surgeons seem to prefer the modified Trauner & Obwegeser (1975) procedure by Dal Pont. Its main advantage is: the entire operation in the mouth, thus avoiding any external scars; can be used to make an appropriate move before and after, so that there is a good bone contact between the two fracture surfaces, to facilitate bone healing. In addition to the above advantages of the surgical method, there are many complications. In 1972, Behrman investigated about 600 patients and found that the most common comorbidities were recurrence, bleeding, and disruption of the mandibular nerve, edema, ascending branch,
