This study aimed to determine the feasibility of a minimal invasive genioplasty (MIG) technique combining a limited vertical incision, endoscopy, and a piezotome.
A total of thirteen patients who underwent primary genioplasty procedures under general anesthesia were evaluated. The feasibility of the method was reported in terms of total surgery time, the total amount of intra-operative blood loss, neurosensory dysfunction, pain sensation, infection, and patient satisfaction using the FACE-Q Chin scale.
We observed the mean surgery time of 46.08 ± 5.33 min with a statistically significant p-value of 0.157. The ANOVA test value for mean neurosensory testing score (NST) was calculated as 5.95 (p = 0.006) for the right side and 7.64 (p = 0.017) for the left side. The paired t-test value of the mean pain score was 117.98 (p < 0.001) and showed no significant pain after 1 week. The quality of the osteotomy was deemed good in 12 patients with less intra-operative blood (ranged from 7.7 to 46.2%).
Based on these results, this minimally invasive technique for genioplasty is a promising approach to perform a chin osteotomy and should be an alternative to the conventional genioplasty technique.
本研究旨在确定一种微创颏成形术（MIG）技术的可行性，该技术结合了有限的垂直切口、内窥镜和超声骨刀。
共评估了 13 名在全身麻醉下接受初次颏成形术的患者。从总手术时间、术中总失血量、神经感觉功能障碍、疼痛感知、感染和患者满意度（使用 FACE-Q Chin 量表）等方面报告了该方法的可行性。
我们观察到平均手术时间为 46.08 ± 5.33 分钟，p 值为 0.157，具有统计学意义。右侧平均神经感觉测试评分（NST）的 ANOVA 检验值为 5.95（p = 0.006），左侧为 7.64（p = 0.017）。平均疼痛评分的配对 t 检验值为 117.98（p < 0.001），且术后 1 周后疼痛明显减轻。12 名患者的骨切开质量良好，术中出血量较少（范围为 7.7 至 46.2%）。
基于这些结果，这种微创颏成形术技术是一种有前途的颏骨切开方法，应作为传统颏成形术技术的替代方法。
