目的:探讨改良鼻旁植骨是否能减少Le Fort 1型截骨下降手术术后上颌骨垂直向的复发。方法:选择双颌手术中上颌骨下降幅度>3 mm的患者30例,分为改良鼻旁植骨组和非改良鼻旁植骨组。利用术前(T0)、术后3天(T1)和术后6个月(T2)的颌面CT...目的:探讨改良鼻旁植骨是否能减少Le Fort 1型截骨下降手术术后上颌骨垂直向的复发。方法:选择双颌手术中上颌骨下降幅度>3 mm的患者30例,分为改良鼻旁植骨组和非改良鼻旁植骨组。利用术前(T0)、术后3天(T1)和术后6个月(T2)的颌面CT数据对上颌骨位置进行三维测量;同时利用T1与T2的CT数据计算植骨块厚度的变化。采用SPSS 22.0软件包对数据进行统计学分析。结果:术后6个月,在垂直方向上,改良鼻旁植骨组上切牙点复发量为(0.54±0.35)mm,非改良鼻旁植骨组上切牙点复发量为(1.18±0.76)mm(P=0.3997)。2组在前后、水平方向的复发率无显著差异。改良鼻旁植骨组的植骨块厚度降低(11.75±6.25)%,非改良鼻旁植骨组的植骨块厚度降低(33.77±11.56)%(P<0.0001)。结果:改良鼻旁植骨可有效减少植骨块吸收,以及术后上颌骨垂直向复发。展开更多

Their prevention is based on the management of cardiovascular risk factors, but also on the early detection and management of chronic coronary syndromes (CCS), for which few data are available in Africa. The main objective of our study was to determine the factors related to significative coronary artery disease in patients undergoing coronarography for suspected chronic coronary syndrome (CCS). Methodology: We conducted a retrospective descriptive and analytical study over 2 years (from January, 1<sup>st</sup>, 2018 to December 31<sup>st</sup>, 2019) in the Cardiology Department of the University Hospital Aristide Le DANTEC in Dakar. All patients admitted for coronary angiography for suspected chronic coronary syndrome were included. Results: One hundred and fifty-two patients were included with a mean age of 60.79 ± 9.73 years, the most represented age group was 60 - 69 years. Advanced age was the most frequent risk factor (77.63%) followed by sedentary lifestyle (56.58%) and hypertension (41.45%). Diabetes was present in 17.1% of cases. A history of angioplasty was found in 1.97% of patients. Typical pain was found in 71.05% of cases, atypical pain in 19.74% and exertional dyspnoea in 2.63%. The pre-test probability was intermediate in 67.1% of cases, low in 25% and high in 7.9%. Significative coronary lesion was found in 52.63% of the patients, while coronary angiography was normal in the remaining cases. Tritroncular status was observed in 37.50%, it was bitroncular in 26.25% and monotroncular in 36.25% of cases. Factors associated with significative coronary artery disease were age (p = 0.0001), diabetes (p = 0.006), previous angioplasty (p = 0.023), previous myocardial infarction (p = 0.018), typical angina (p = 0.001), intermediate pretest probability (p = 0.001). Low pretest probability was significantly correlated with the absence of a coronary lesion with a p = 0.001. Conclusion: Our study shows that screening for chronic coronary disease should be done especially in diabetics, elderly subjects and those with previous angioplasty taking into account symptoms and pretest probability to avoid unnecessary invasive procedures.展开更多
