Soft tissue changes of the upper and lower lips and the chin after mandibular vestibulolingual sulcoplasty with free skin grafting have been evaluated between one and five years postoperatively. Increases in chin prominence averaging 2.5 mm appeared within the first year after the operation. Prominence of the chin then remained unchanged at least through five years. A mean decrease in the height of the lower lip of 2.6 mm was found. These changes are possible complications of mandibular vestibulolingual sulcoplasty with free skin grafting, and must be considered in the final choice of preprosthetic surgery to be performed on a given patient.
对采用游离皮片移植的下颌前庭舌沟成形术后一至五年上下唇及颏部的软组织变化进行了评估。术后第一年颏部突出度平均增加2.5毫米。颏部突出度随后至少五年保持不变。发现下唇高度平均下降2.6毫米。这些变化是采用游离皮片移植的下颌前庭舌沟成形术可能出现的并发症，在为特定患者选择最终的修复前手术时必须予以考虑。
