To compare the characteristics of microtia in Finland and in other populations.
Retrospective case series and patient questionnaire of 190 microtia patients referred for reconstruction of the earlobe to the Helsinki University Central Hospital during the years 1980-2005.
The prevalence in Finland is 4.34/10,000 and varied in other populations from 0.83 to 17.4/10,000. Microtia is seen more in males (58%), as unilateral (88.4%), right-sided (59.5%) and it is almost always associated with aural atresia or stenosis (93%). There is conductive hearing loss in 96% and sensorineural hearing loss in 8% of the affected ears. 11% of the patients had congenital heart defects, and 5% had anomalies of extremities.
There is variation in the prevalence and characteristics of microtia in different populations.
比较芬兰及其他人群中耳畸形的特征。
对1980年至2005年间转诊至赫尔辛基大学中心医院进行耳垂重建的190例耳畸形患者进行回顾性病例系列研究及患者问卷调查。
芬兰的患病率为4.34/10000，其他人群的患病率在0.83至17.4/10000之间。耳畸形在男性中更为常见（58%），多为单侧（88.4%）、右侧（59.5%），且几乎总是与耳道闭锁或狭窄相关（93%）。患耳中96%有传导性听力损失，8%有感音神经性听力损失。11%的患者有先天性心脏缺陷，5%有肢体畸形。
不同人群中耳畸形的患病率及特征存在差异。
