隐耳的治疗与新分类法

CRYPTOTIA:OUR TREATMENT AND CLASSIFICATION

隐耳是一种先天性耳廓畸形,日本人隐耳的发生率比白种人高,约为400∶1,但本畸形在其他东方民族的发生率尚不清楚。作者根据耳廓畸形的形态和耳廓肌肉的状态,将隐耳分为两型。即对耳轮上脚型(耳廓横肌型)和对耳轮下脚型(耳廓斜肌型)。 本文介绍了一种用曲别针和头皮静脉穿刺针的塑料管制成的矫治器用来治疗隐耳的非手术方法,这种非手术疗法对1周岁以内的患儿有效。与已经报道的方法相比较,此法具有许多优点。

Cryptotia is a congenital auricular deformity,in which the upper portion of the auricle is buried beneath the temporal skin and can be pulled out,but it returns to its original position when released.The incidence of cryptotia is higher among the Japanese than among Caucasians and is approximately 1 in 400,but the incidence among Orientals other than Japanese is unknown.We present a nonsurgi-cal method of correcting cryptotia by using a device made up of a paper clip and the plastic tube of a scalp vein puncture needle.This nonsurgical method of treatment is effective for patients under 12 months of age.A new surgical method of correcting cryptotia by using a rotation flap to cover up the cartilage deformity is also presented.This method has a number of advantage over previously reported ones.We classify cryptotia into two types according to the antihelical deformity and the intrinsic muscle,namely,superior crus type (transverse muscle type) and inferior crus type (oblique muscle type).
