The learning curve as a concept has been considered, discussed and debated in medical education and healthcare for over two decades. The precise usage has been recognised in surgical disciplines both broad specialties and sub-specialties. Rollin Daniel in his book stated that, rhinoplasty is the most difficult of all cosmetic operations for three reasons, (a) nasal anatomy is highly variable, (b) the procedure must correct form and function and (c) the final result must meet the patients expectations. With this in mind a study was carried on the perception of learning curve in rhinoplasty based on a surgeon questionnaire at Marien Hospital, Stuttgart, Germany under Prof. Gubisch. Aims of the study were, (1) to extract the perception of learning curve of Rhinoplasty from surgeons across a spectrum of experience, i.e. less experienced to experienced, (2) To calculate the perception of learning curve in rhinoplasty as for other surgical procedures i.e. minimum number, interquartile range, surgical time, accelerators, (3) To chart-out a road-map for a novice rhinoplasty surgeon for continued improvement in surgical skills and ability. The conclusion derived was the concept of learning curve in rhinoplasty cannot be applied to the operation of Septo-Rhinoplasty as a whole because the two factors i.e. interquartile range and minimum number to achieve proficiency have a wide range and cannot be generalized. It is thought that each type of Rhinoplasty should be dealt with separately and learning curve calculated accordingly, i.e. hump reduction, crooked nose and augmentation rhinoplasty.
作为一个概念,学习曲线在医学教育和医疗保健领域已被思考、讨论和辩论了二十多年。其确切用法在外科领域的各个专业和亚专业中都已得到认可。罗林·丹尼尔在他的书中指出,隆鼻手术是所有整形手术中最难的,原因有三点:(a)鼻解剖结构高度多变;(b)该手术必须同时矫正形态和功能;(c)最终结果必须符合患者的期望。基于此,在德国斯图加特玛丽恩医院古比施教授的指导下,针对隆鼻手术学习曲线的认知开展了一项基于外科医生问卷的研究。该研究的目的包括:(1)从经验各异(从经验较少到经验丰富)的外科医生中提取对隆鼻手术学习曲线的认知;(2)计算隆鼻手术学习曲线的相关参数,如同其他外科手术那样,即达到熟练所需的最少例数、四分位距、手术时间、促进因素;(3)为初涉隆鼻手术的外科医生绘制一条路线图,以持续提升其手术技能和能力。得出的结论是,隆鼻手术学习曲线的概念不能整体应用于鼻中隔隆鼻手术,因为四分位距和达到熟练所需最少例数这两个因素范围较宽,无法一概而论。人们认为,每种隆鼻手术类型都应单独处理,并据此计算学习曲线,即驼峰鼻矫正术、歪鼻矫正术和隆鼻术。
