A cephalometric analysis of the submental-cervical region was carried out by examining and comparing 16 white adults who had ideal submental-cervical esthetics with 16 adult orthognathic surgery patients who were treated by submental lipectomy or liposuction and various orthognathic surgical procedures. A normative data base of the submental-cervical region was derived from the ideal subject group. The submental-cervical morphology of the preoperative patients differed significantly from the ideal subjects. The submental-cervical angle (Sm-Ce) and the submental soft tissue thickness at C point (IBM-Sm) presented the greatest disparity between the ideal subjects (118.0 degrees, 28.0 mm) and the preoperative patients (158.3 degrees, 42.1 mm, each P < .001). After surgery, Sm-Ce and IBM-Sm decreased to 132.8 degrees (P < .001) and 28.7 mm (P < .001), respectively. By the end of 6 months postoperative, the mean values of Sm-Ce and IBM-Sm were 131.1 degrees and 28.6 mm. The submental soft tissue thickness of the patients 6 months after surgery was not statistically different from the ideal subjects (each P > .05). Orthognathic surgical procedures with concomitant submental lipectomy or liposuction had a significant effect on the contour of the submental and cervical soft tissues.
通过检查和比较16名具有理想颏下-颈部美学的白人成年人与16名接受颏下脂肪切除术或抽脂术以及各种正颌外科手术治疗的成年正颌外科患者，对颏下-颈部区域进行了头影测量分析。从理想受试者组得出了颏下-颈部区域的标准数据库。术前患者的颏下-颈部形态与理想受试者有显著差异。理想受试者（118.0度，28.0毫米）与术前患者（分别为158.3度，42.1毫米，各P <.001）之间，颏下-颈部角（Sm-Ce）和C点处的颏下软组织厚度（IBM-Sm）差异最大。手术后，Sm-Ce和IBM-Sm分别降至132.8度（P <.001）和28.7毫米（P <.001）。术后6个月末，Sm-Ce和IBM-Sm的平均值分别为131.1度和28.6毫米。术后6个月患者的颏下软组织厚度与理想受试者相比无统计学差异（各P>.05）。正颌外科手术联合颏下脂肪切除术或抽脂术对颏下和颈部软组织轮廓有显著影响。
