■调查使用计算机辅助手术(CAS)对最初计划的颌面重建的依从性,并确定影响其对颌面重建依从性的影响因素。
■对2014年1月至2020年6月的136例计算机辅助颌面重建手术进行了回顾性分析。分类参数涉及年龄,性别,疾病病因,疾病部位,缺陷尺寸,骨瓣段,和皮瓣类型。除了描述性数据报告之外,分类数据通过应用Fisher精确检验进行关联,且p值低于5%被认为具有统计学意义(P<0.05)。
■部分或不坚持的主要原因包括不适合,患者健康状况,和其他主观原因。在患者总数中,与18例中面重建(72.2%)相比,接受下颌骨重建的118例患者表现出更高的CAS依从性(83.9%),没有任何统计学上的显着差异(p=0.361)。根据缺陷的大小,与大尺寸缺陷(74.1%)相比,CAS依从性明显更高(p=0.031),缺陷较小(80.6%).与具有少于两个节段的骨瓣相比,具有两个或更多个节段的骨瓣明显(p=0.003)倾向于观察到计划的CAS的部分(15.4%)或完全(12.8%)丢弃。与其他疾病相比,恶性肿瘤的CAS依从性最低,没有任何显着差异(p=0.1)。
■颌面重建外科手术提供了对最初计划的CAS的最佳依从性。然而,大尺寸缺损和多个骨瓣段显示部分或完全放弃CAS的风险较高.
UNASSIGNED: To investigate the adherence to initially planned maxillofacial reconstructions using computer-assisted surgery (CAS) and to identify the influential factors affecting its compliance for maxillofacial reconstruction.
UNASSIGNED: A retrospective analysis of 136 computer-assisted maxillofacial reconstructive surgeries was conducted from January 2014 to June 2020. The categorical parameters involved age, gender, disease etiology, disease site, defect size, bone flap segments, and flap type. Apart from descriptive data reporting, categorical data were related by applying the Fisher-exact test, and a p-value below 5% was considered statistically significant (P < 0.05).
UNASSIGNED: The main reasons for partial or non-adherence included unfitness, patient health condition, and other subjective reasons. Out of the total patient population, 118 patients who underwent mandibular reconstruction showed higher CAS compliance (83.9%) compared to the 18 midface reconstruction (72.2%) without any statistically significant difference (p = 0.361). Based on the size of the defect, a significantly higher CAS compliance (p = 0.031) was observed with a minor defect (80.6%) compared to the large-sized ones (74.1%). The bone flaps with two or more segments were significantly (p = 0.003) prone to observe a partial (15.4%) or complete (12.8%) discard of the planned CAS compared to the bone flaps with less than two segments. The malignant tumors showed the lowest CAS compliance when compared to other disorders without any significant difference (p = 0.1).
UNASSIGNED: The maxillofacial reconstructive surgical procedures offered optimal compliance to the initially planned CAS. However, large-sized defects and multiple bone flap segments demonstrated a higher risk of partial or complete abandonment of the CAS.
