[摘 要] 目的:分析牵引成骨术(Distraction osteogenesis,DO)矫治唇腭裂术后继发颌骨畸形临床效果,探讨其对患者颌骨畸形及语音的影响。方法:分析我院37例采用DO术矫治唇腭裂术后继发颌骨畸形患者资料,观察矫治前、矫治后12个月X线头影变化,并对其矫治后12个月语音效果进行评价。结果:患者矫治后12个月后SNA、G-Sn-Pg、Ls-E plane、H角显著增加,差异有统计学意义(P<0.05),其G-Prn显著降低,G-Sn、G-Ls均显著增加,差异有显著统计学意义(P<0.01)。患者矫治后12个月语音效果优22例,良10例,差5例,优良率86.5%。结论:DO能够有效促进唇腭裂术后继发颌骨畸形患者上颌骨前移,减轻口颌系统继发畸形及功能障碍,保证语音效果、改善面形。

[Abstract] Objective: To analyze the clinical effects of DO (distraction osteogenesis, DO) correction of secondary maxillary deformities following cleft lip and palate surgery, and investigate its impact on the patients jaw bone deformity and voice. Methods: 37 cases of using DO in correcting secondary maxillary deformities following cleft lip and palate surgery in our hospital, observed X cephalometric changes before treatment and 12 months later, and evaluated voice quality of their treatment after 12 months. Results: The SNA, G-Sn-Pg ‘, Ls-E plane and angle H in patients were cantly increased 12 months after treatment, and the difference was statistically significant (P<0.05), G-Prn significantly reduced, both G-Sn and G-Ls were ificantly increased, and the differences were statistically significant (P<0.01). 12 months after treatment, good voice effect in 22 cases, fair in 10 cases and poor in 5 cases, good rate of 86.5%. Conclusions: DO can effectively promote maxillary advancement in patients with secondary maxillary deformities following cleft lip and palate surgery; mitigate secondary deformity and dysfunction of stomatognathic system, ensure voice quality, and improve surface shape.

据统计,65岁以上的老年人中大约5%以上患有颈动脉粥样硬化进而引起颈动脉狭窄[1]。颈动脉狭窄是引起脑卒中的主要原因之一,而后者已经成为我国人群首要死亡原因,且致死致残率极高[2-3]。目前,颈动脉狭窄的主要治疗方法主要有3种:药物治疗、颈动脉内膜剥脱和颈动脉支架置入术。但是有关颈动脉狭窄患者的CAS和CEA治疗一直是医学界讨论的热点,并且一些临床研究得出的结果也不尽相同,因此本研究也将探讨颈动脉支架置入术和颈动脉内膜剥脱术用于颈动脉狭窄患者的安全性和有效性,为颈动脉内膜狭窄患者治疗提供一定参考。
1 资料与方法
1.1 一般资料
回顾性分析我院2014年7月至2015年7月进行颈动脉狭窄手术治疗78例患者资料,年龄55~75岁,ASA I~Ⅲ级,所有患者术前根据临床症状、头部CT以及脑血管造影检查确诊为颈动脉狭窄,且狭窄范围>70%,根据患者治疗方式不同分为CEA组(48例)和CAS组(30例)。排除指标:急性脑梗、脑出血;病变颈动脉完全闭塞;……
