Breast Augmentation for Pectus Carinatum (Pigeon Chest) or Pectus Excavatum (Sunken Chest)


In most cases, performing a breast augmentation cosmetic surgical procedure is a relatively straightforward process. However, there are some congenital deformities to the chest wall structure that may require the cosmetic surgeon to take extra care in performing a breast augmentation procedure. Two such deformities are pectus carinatum or pectus excavatum. Both require extra care in terms of implant positioning and profile.

Pectus Carinatum

Pectus carinatum, or “pigeon chest,” is a congenital deformity of the rib cage and sternum in which the breast bone overly protrudes, giving the chest a bird-like appearance. This condition occurs in approximately one in 400 patients. The entire chest wall is bowed outward because the sternum protrudes outward, with depressions along the sides of the chest. Although this condition does not affect the development of the heart and lungs, patients may have pulmonary difficulties due to a chest wall that will appear very rigid. Correction for this condition in severe cases may involve repositioning the sternum with wires or rods.

The goals in breast augmentation for these patients are to reduce the appearance of the protruding sternum, while still creating natural looking cleavage. High profile implants (in which the height of the implants is greater than the base width) placed behind the chest muscles (subpectorally) will reduce the appearance of a protruding sternum. This will produce more natural appearing cleavage. However, patients must be aware that the implants may become displaced to the outer sides of the chest over time if they do not wear a bra. Dr. Vincent Marin recommends patients wear a nocturnal breast support garment to prevent this implant displacement.

Pectus Excavatum

By contrast, cases where the chest bows inward are known as pectus excavatum, or “sunken chest.” This is actually the most common of all congenital chest deformities. Patients with this condition will have a sternum that appears pressed inward relative to the rest of the chest wall. The ribs may also be depressed, which furthers the concave appearance of the chest. Although patients will not have any symptoms in most cases, they can have cardiac difficulties if the heart is compressed between the sternum and the spine.

Patients with this condition will often consider breast augmentation in order to reduce the appearance of the hollowed out chest. In such cases, low profile implants (in which the implant height is less than the width) placed under the pectoral muscles are preferred. Because chest tissue in patients with pectus excavatum tends to be thin, placing implants over the chest muscle may increase chances for visible implant rippling.

Just as with pectus carinatum, patients with sunken chests who undergo breast augmentation may also experience implant displacement if they do not wear a bra on a regular basis. However, in these cases, the implants may shift toward the sternum, creating the “uniboob” effect. Dr. Marin would also recommend a nighttime support garment to help hold the implants in place.
