简介:日益增长的白内障盲表明目前白内障手术数量还远远低于清除白内障积存数及服务新发病人的要求。经济状况越好,文化程度越高,对视力的要求也会越强烈,病人也会更早地要求实施白内障手术。老年人口的增加也会使得白内障手术的需求成倍增加。即使在印度,白内障手术率(CSR)高达每百万人口3250例,白内障手术率仍然需要提高2-3倍,才能有效地解决白内障盲的问题。在很多国家,白内障手术率甚至要提高10倍才能解决问题。增加白内障手术服务本身就是一个极大的挑战。同样具有挑战的是保证服务的质量。这需要不断增加的资源(扩充容量)及最大限度地使用现有资源(提高效率)。本文中讨论在现有服务制度下,如何扩充容量,提高效率,这正是很多地方所需要的。
简介:上海交通大学医学院(原上海第二医科大学)附属仁济医院是一所历史悠久的三级甲等教学医院(建院于1844年),耳鼻咽喉科和我国大多数的兄弟医院一样,多年来一直从事如急慢性中耳炎、急慢性咽、喉炎、扁桃体炎、耳鸣、耳聋等临床常见病、多发病的医疗、教学及研究工作,近年来由于疾病谱的变化我们除常规的传统工作之外,每年对头颈肿瘤患者的诊治也逐渐增多。2005年仅甲状腺肿瘤的外科手术治疗达500多例,近10余年总数超过5000例,约占本科手术总量的45%。作为以传统耳鼻咽喉科为主的三级甲等医院中的一员,从开始每年10余例甲状腺肿瘤手术到目前每年500余例,并进行涎腺肿瘤外科、头颈部先天性肿瘤、头颈部外伤治疗,开展了颈胸联合、颅鼻联合手术等工作,逐渐发展成为具初步规模的耳鼻咽喉头颈外科,我们走过了10余年的历程,有了些感受,现就有关耳鼻咽喉头颈外科医师进行甲状腺肿瘤外科治疗的若干体会与从事相关工作的同道们进行交流、切磋。

简介:目的探讨鼻内镜辅助下颈前小切121甲状腺手术的疗效、临床经验和手术注意事项,并与传统手术进行比较。方法我科术前确诊的单发甲状腺腺瘤患者26例,肿瘤最大直径〈4.0cm,均行鼻内镜辅助颈前小切口腺叶切除术,观察疗效,并与同期具有可比性的30例经传统手术治疗的患者资料进行比较。结果2组患者的肿块均完整切除,切口均Ⅰ期愈合。术后无声音嘶哑、呛咳、继发血肿等并发症。无手术死亡病例。鼻内镜辅助下颈前小切口组的手术时间较对照组长(t=9.139,P〈0.05),术中出血量较对照组大(t=12.648,P〈0.05)。小切口组患者的瘢痕长度、患者满意度、住院天数明显优于对照组,差异有统计学意义(P〈0.05)。结论鼻内镜辅助下颈前小切口甲状腺手术安全、可靠,能有效避免神经、血管损伤,具有并发症少、微创、美容的优点,值得临床推广。
