Case Study – Custom Chest Wall Implant as a Breast Implant Platform

Wednesday, December 13th, 2017

 

Background: Precuts excavatum or funnel chest is a well known congenital chest wall deformity. It affects the midline sternum and the adjoining ribs which is expressed in a sunken appearance to the chest most commonly seen down the middle. Various expressions of pectus excavatum exist where one side is more affected than the other resulting in chest wall asymmetry as well.

Surgical treatment of pectus excavatum has evolved over the years with the Nuss procedure using a pectus bar as the most contemporary method. But it does not always provide a complete correction since it relies on an outward pressure or push by the underlying bar.  Residual chest wall deformities do remain in some treated particularly when done in older patients.

In adults with residual chest wall deformities secondary procedures exist such as pectoral implants in men and breast implants in women. While most effective in more symmetrical chest wall deformities, the asymmetrical chest wall deformity is more challenging with secondary implant camouflage.

Case Study: This middle-aged female had her pectus excavatum chest wall deformity treated much later in life due to underdiagnosis and its significant asymmetry. It was treated by a pectus bar which relieved her pulmonary symptoms but still left her with a significant chest asymmetry. Breast implants were placed  to help with the asymmetry as well as increase the size of her breasts. But differential breast implant sizes did not adequately correct the problem. Despite a larger breast implant on the affected left side, the breasts and lower ribcage still appeared significantly asymmetric

Using a 3D CT, a custom chest wall implant was designed to fill in the deficiency. This  would serve as the platform onto which the breast implant would sit. The size of the custom chest wall implant was 272cc which should help in calculating what size breast implant is needed to match that of other side.

Under general anesthesia her existing breast implant was removed which revealed the extent of the chest wall deformity which extended down to the subcostal margin. The custom chest wall implant was inserted and sutured into position around its perimeter. The breast implant was re-inserted back on top of the custom implant which gave it more more anterior projection.

With significant chest wall asymmetry from pectus excavatum and its subsequent repairs,  a custom chest wall implant can restore the chest wall shape. This serves as a platform onto which to place a breast implant in women or incorporate it into a custom sterno-pectoral implant for men.

Highlights:

1) Pectis excavatum and its subsequent repairs can still leave residual chest wall deformities.

2) In females breast implants alone can often not adequately camouflage a chest wall deformity.

3) A custom chest wall implant can serve as as foundation onto which a breast implant can be placed.
