AB  - OBJECTIVE: The purpose of this study was to analyze the long-term changes in the 
      horizontal transverse mandibular width (TMW) between the angles of mandible after 
      intraoral vertical ramus osteotomy (IVRO) with respect to hard and soft tissues. 
      STUDY DESIGN: A total of 107 from a pool of 207 patients with mandibular 
      prognathism who had undergone bilateral IVRO were retrospectively evaluated 
      radiographically and photographically. A comparison study of the changes of 
      horizontal transverse width in hard and soft tissues after surgery was performed 
      using preoperative, and 1-, 3-, 6-, and 12-month postoperative posteroanterior 
      (PA) cephalograms and clinical photos. Three groups were divided according to the 
      amount of mandibular setback performed (Group 1: <5 mm, Group 2: 5-10 mm, Group 
      3: >10 mm). RESULTS: The overall average amount of mandibular setback in all 
      patients was 8.58 mm. Statistically significant increases of TMW in hard and soft 
      tissue from preoperative to postoperative 1 month were seen. TMW in hard tissue 
      showed a gradually decreasing pattern postoperatively from 1 month to 1 year, and 
      the changes were statistically significant at 1 year postop. TMW in soft tissue 
      was not changed uniformly after 1 month, and showed less than 1% change at 1-year 
      postoperatively compared with preoperatively. The amount of increase in the TMW 
      postoperatively was not proportional or statistically significant to the amount 
      of mandibular setback performed. CONCLUSIONS: The results show that mandibular 
      setback using BIVRO did not significantly influence the TMW changes in soft 
      tissue. Therefore, IVRO technique can be safely used without compromising 
      esthetic results through soft tissue TMW increase.
