The internal mammary artery perforator (IMAP) breast-flap harvested from an asymmetric hyperplastic breast for correction of a mild funnel chest deformity.

Pectus excavatum deformity is the most frequent congenital anomaly of the thoracic wall. If the invasive surgical procedures of thoracoplasty are not indicated or the patient refuses them, alternative treatment options should be considered. In such cases, local or distant transposition of autologous tissue could be appropriate. This report presents a selected case of funnel chest deformity and concomitant unilateral breast hyperplasia. Both deformities were corrected simultaneously using a pedicled internal mammary artery perforator (IMAP) flap dissected from the hyperplastic breast. This is a safe, reliable, low-morbidity, one-stage option for adult women that uses an easy-to-harvest flap for simultaneous correction of mild funnel chest deformity and concomitant breast hyperplasia with a single resulting scar.
