Abstract: Mixed-type asymmetric thoracic deformity has two malformations in left to right parallel arrangement.
Although the deformity is regarded as a simple addition of pectus carinatum and pectus excavatum, the
sandwich procedure will not bring ideal results. We designed a minimally invasive technique using one or
two metal bars to correct the protrusion and depression at the same time, and our preliminary clinical
experience shows a satisfactory result.Keywords: asymmetric thoracic deformity, minimally invasive, operation
