摘要

目的：该研究旨在评估自体脂肪隆下巴或镶嵌PEEK材料与滑动基底成形术在矫正下巴后缩患者下巴缺损方面的软组织外形变化。将患者分为三组：自体脂肪隆颏组作为干预I组，PEEK材料隆颏组作为干预II组，骨性基底成形术组作为对照组。所有患者均进行了术前和术后 CBCT 检查。借助 MIMICS、3-MATIC 和 PROPLAN 软件进行诊断、虚拟规划和评估。结果：与对照组相比，脂肪组在 6 个月后软组织复发方面有显著统计学差异（平均差异= 0.770），而 PEEK 组与对照组在软组织复发方面没有显著统计学差异（平均差异= -0.060）。组内比较显示，各组在随访期间软组织复发方面均无统计学意义上的显著差异（脂肪组 P = 0.1389，PEEK 组 P = 0.8739，对照组 P = 0.8410）。所有患者在随访期间对下巴的满意度评分都有显著提高（P = 0.0165、P = 0.0150 和 P = 0.0293）：结论：对于轻度-中度下巴缺损的病例，脂肪隆下巴是一种很好的干预选择。PEEK PSI手术效果稳定。

Evaluation of soft tissue profile changes following autogenous fat or onlay PEEK augmentation versus sliding genioplasty for correction of deficient chin: Randomized controlled clinical trial

Aim

The study was conducted to evaluate soft tissue profile changes using autogenous fat augmentation or onlay PEEK versus sliding genioplasty for correction of deficient chin in patients with retruded chin.

Material and methods

Thirty-three patients with deficient chins were included in the study. The patients were distributed into 3 groups: the fat augmentation group as intervention I, the PEEK augmentation group as intervention II, and the osseous genioplasty group as control group. Preoperative and postoperative CBCT were performed for all patients. With the aid of MIMICS,3-MATIC, and PROPLAN software, diagnosis, virtual planning, and evaluation were performed. The Face-Q questionnaire was used to assess patient satisfaction.

Results

There was a statistically significant difference regarding soft tissue relapse in the fat group after 6 months when compared to the control group (mean difference= 0.770), while there was no statistically significant difference regarding soft tissue relapse between PEEK and control group (mean difference= -0.060). Intragroup comparison has shown no statistically significant difference regarding soft tissue relapse within all groups between follow-up periods (P = 0.1389 for the fat group, P = 0.8739 for the peek group, and P = 0.8410 for the control group). All patients showed a statistically significant increase in scores of satisfaction with the chin between follow-up periods (P = 0.0165, P = 0.0150, and P = 0.0293) respectively.
