The study of the angle of caudal declination of the ribs in 19 children aged 5 years, and in 23 children aged 8 years undergoing pectus excavatum repair, established that children with deformity had significantly wider angle compared to children of the same age without chest deformity. The angle of declination was not significantly changed 3 years after the operation. Thus it was concluded that subperichondral excision of the rib cartilage and osteotomy of the sternum led to fixed chest position. These data can explain persistent pulmonary dysfunction of the restrictive type in spite of successful aesthetic correction of the deformity.
对19名5岁儿童和23名8岁接受漏斗胸修复手术的儿童的肋骨尾侧倾斜角度进行研究后发现，与同龄无胸部畸形的儿童相比，畸形儿童的倾斜角度明显更宽。术后3年，倾斜角度没有明显变化。因此得出结论，肋骨软骨的软骨膜下切除和胸骨截骨术导致胸部位置固定。这些数据可以解释尽管畸形在美学上得到成功矫正，但仍存在限制性类型的持续性肺功能障碍。
