Asphyxiating thoracic dystropy can be divided into two types: type I is cylindrical with slight depressions on chest wall, and type II is non-cylindrical with serious depressions on the chest wall. The nature of the depressions determines the choice of operation. For type I patients, the relatively reasonable operation is median thoracic expansion. However, due to the existence of depressions, the effect is not ideal. In order to eliminate the effect of depression, we designed a operation with an additional Nuss procedure to median thoracic expansion. We applied this operation to a 3-year-old patient and achieved good results.
