目的:本研究的目的是评估双瓣腭成形术(TFP)与颊肌粘膜瓣Furlow腭成形术(FPBF)对原发性牙列期儿童上颌弓尺寸的影响与没有任何颅面异常的匹配对象相比。
方法:这项研究包括28名年龄在5-6岁的受试者;对照组包括10名非left裂受试者,9例患者接受TFP治疗,9例患者接受FPBF治疗。对于纳入的患者,使用桌面扫描仪扫描上颌模型以产生虚拟模型,上颌尺寸测量几乎完成。在3组之间比较产生的测量值。评估了28名参与者的上颌模型。
结果:在3组之间检测到足弓对称性测量的统计学差异不显著。2个手术组和非裂隙组之间的犬间宽度存在差异。足弓长度和后腭深度与对照组相比有显着差异,FPBF和非裂隙组之间没有差异。
结论:对于left裂患者,在评估上颌弓尺寸作为手术结果的同时,使用颊肌粘膜瓣进行的下沟腭成形术可能被认为是一种比两种瓣腭成形术更好的手术选择。
结论:这项研究提供了对上颌生长和牙弓尺寸影响有限的外科技术的见解。因此,它减少了正畸治疗和正颌手术的需要。
背景:临床试验(NCT05405738)。
OBJECTIVE: The objective of this study was to evaluate the effect of two flap palatoplasty (TFP) versus Furlow palatoplasty with buccal myomucosal flap (FPBF) on maxillary arch dimensions in children at the primary dentition stage with cleft palate, in comparison to matching subjects without any craniofacial anomalies.
METHODS: This study included 28 subjects with an age range of 5-6 years; 10 non-cleft subjects were included in the control group, 9 patients treated with TFP, and 9 patients treated with FPBF. For the included patients, the maxillary models were scanned using a desktop scanner to produce virtual models, and the maxillary dimension measurements were virtually completed. The produced measurements were compared between the 3 groups. Maxillary models of the 28 participants were evaluated.
RESULTS: Statistically insignificant differences were detected between the 3 groups for arch symmetry measurements. Differences were detected in the inter-canine width between the 2 surgical groups and non-cleft group. Both arch length and posterior palatal depth significantly differ while comparing the TFP to the control group, with no differences between FPBF and the non-cleft group.
CONCLUSIONS: Furlow palatoplasty with buccal myomucosal flap might be considered a better surgical option than two flap palatoplasty for patients with cleft palate while evaluating maxillary arch dimensions at the primary dentition stage as a surgical outcome.
CONCLUSIONS: This study gives insight into the surgical technique that has limited effect on the maxillary growth and dental arch dimension. Therefore, it decreases the need for orthodontic treatment and orthognathic surgery.
