Here mentolabial form including lateral facial contour and bony contour in healthy adults was studied to refer to values of normal mentolabial form using lateral roentgen cephalography. In soft tissue of healthy adults, thickness of mentolabial soft tissue was greater for men than for women. Degree of mentolabial curvature was greater for men than for women. In severe facial burn patients, the micrognathia-like deformity was evaluated compared with the reference values. In soft tissue of severe facial burn patients, loss of mentolabial sulcus and eversion of the lower lip were characteristically analyzed, suspecting that the major cause was scar contracture. These statistical data contribute to reconstruction of micrognathia-like deformity after severe facial burn to lead to favorable mentolabial form. It is shown that osteotomized genio-advancement produced ideal mentolabial form in severe facial burn patients, who had not been satisfied with the form by conventional operative methods, free skin flap, skin flap or free skin graft. And that the analyzed data, especially in the parameter of thickness of mentolabial sulcus, was improved.
本研究采用头颅侧位X线摄影术，对健康成年人的颏唇形态（包括面部侧面轮廓和骨质轮廓）进行研究，以获取正常颏唇形态的参考值。在健康成年人的软组织中，男性颏唇软组织厚度大于女性。男性颏唇弯曲程度大于女性。对于重度面部烧伤患者，将其类小颌畸形与参考值进行比较评估。在重度面部烧伤患者的软组织中，对颏唇沟消失和下唇外翻的特征进行分析，怀疑主要原因是瘢痕挛缩。这些统计数据有助于重度面部烧伤后类小颌畸形的重建，以获得良好的颏唇形态。结果表明，对于那些对传统手术方法（游离皮瓣、皮瓣或游离皮肤移植）所形成的形态不满意的重度面部烧伤患者，颏部截骨前移术可产生理想的颏唇形态。并且所分析的数据，尤其是颏唇沟厚度参数得到了改善。
