Cosmetic evaluation of surgical scars after external dacryocystorhinostomy

引用

International Journal of Ophthalmology(English edition) 2016年第12期9卷 1745-1750页

作者： Syed ali raza Rtzvi Mohammad Saquib Rakesh Maheshwari Yogesh Gupta Zafr Igbal Purleet Maheshwari Institute of Ophthalmology Jawaharlal Nehru Medical College AMU Aligarh.UP 202002 India Department of Oto-Rhino-Laryngology Jawaharlal Nehru Medical College AMU Aligarh.UP 202002 India Department of Oto-Rhino-Laryngology Era's Lucknow Medical College and Hospital Lucknow.UP 226003 India

AIM： To evaluate the surgical scars of external dacryocystorhinostomy （DCR） cosmetically. METHODS： Totally 50 consecutive cases of primary acquired nasolacrimal duct obstruction （PANDO） were included in the study. Surgical scars were assessed by the patients and two independent observers at 2, 6 and 12wk postoperatively on the basis of visibility of the scars and still photographs respectively and were graded from 0-3. Kappa test was utilised to check the agreement of scar grading between the two observers. Wilcoxan signed ranks test was used to analyse the improvement of scar ***： Thirty-four （68%） patients graded their incision site as very visible （grade 3） at 2wk. At 6 and 12wk, incision site was observed as grade 3 by 7 （14%） and 1 （2%） patients respectively. Photographic evaluation of patients by 2 observers showed an average score of 2.75, 1.94 and 0.94 at 2, 6 and 12wk respectively. Change in scar grading from grade 3 to grade 0 in consecutive follow-up （2, 6 and 12wk） was found to be highly significant both for the patient as well for the observers （P〈0.0001）.CONCLUSION： The external DCR is a highly effective and safe procedure and in view of low percentage of cases who complained of marked scarring in the present study, thus scarring should not be the main ground for deciding the approach to DCR surgery, even in young cosmetically conscious patients.

质子交换膜燃料电池(PEMFC)由于其较高的发电效率和常温工作稳定性而被广泛关注。传统PEMFC由于电堆内部发电负载不均匀,容易发生“水淹”等问题。大多数研究基于在单电池层面上通过改变流场结构的方法优化PEMFC,但PEMFC工作时往往是组装电堆的形式。为此,设计带有竖直流道作为反应物进出口的单电池电堆结构,并提出一种新型的串联补偿流场,采用3个进气口,并具有首尾互相串联的3个流道,流道之间可以互相补偿反应物。使用ANSYS软件基于单层电堆层面进行仿真模拟研究,保证阳极是相同蛇形流场的情况下,阴极分别采用传统单流道蛇形流场和新型串联补偿流场,分析单层PEMFC电堆中多孔介质层(即扩散层(GDL)和催化层(CL))的电流密度、氧气质量分数、液态水饱和度、速度矢量和流道压力的分布规律。仿真结果表明:传统单流道蛇形流场单层PEMFC电堆中,整体管道压降较高,电流密度和氧气质量分数较高的区域集中在入口段,越靠近出口段分布越少;出口段液态水饱和度较高而速度矢量没有明显升高,液态水容易囤积在出口段;新型串联补偿流场,电流密度分布相对均匀,氧气质量分数有多个较高的区域,分布更加广泛,电化学反应更加充分,整体压降较低,在氧气质量分数较高的区域,速度矢量明显较高,促使氧气在多个流道间快速补充和扩散,整体液态水饱和度相对较低,出口段同样速度矢量较高,排水效果增强。
