How to treat Pectus Excavatum ?

Author : Pr Jean-Pierre Chavoin, ex-Head of Plastic Surgery Department of Toulouse University Hospital, ex-President and General Secretary of French Plastic Surgery Society.

Pectus Excavatum is a malformation of the thorax characterised by a median or lateral depression of the sternum. As concerns women, it can lead to breast's deformity or asymmetry. Funnel chest occurs in 1 to 2% of the population. The impact is mainly aesthetic and psychological, and very rarely functional.

The 3D custom-made implant technique consists of filling the "hole" in the chest without touching the rib cage unlike traditional orthopedic techniques such as Nuss or Ravitch. Each implant is designed to adapt to the patient's own anatomy. The intervention is simple and painless with a quick recovery. The results are immediate.

Pectus Excavatum : 3D custom-made technique

 

 

Custom technique

Each implant is unique and customised for each patient :

  • Realisation of a chest scan at the hospital
  • Segmentation of all tissues and production of a virtual copy of the patient's body
  • Design of the virtual implant that adapts perfectly to the recipient site
  • Machining of a prototype, perfect copy of the implant, for the development of a mold
  • Final manufacturing of the silicone implant from the mold

Custom-made implant

Silicone implant

Implants are made with the latest-generation polymerised silicone and are definitive :

  • Medical-grade polymerized silicone rubber from NuSil, registered with the FDA (Food & Drugs Administration)
  • Smooth implants , puncture-resistant and tear-proof gum, no risk of rupture or shrink shell as for silicone gel breast implants
  • implants are then manufactured by our partner SEBBIN according to the standards ISO 9001 and ISO 13485 meeting the requirements of the European Directive 93/42

Pectus Excavatum Surgery

The surgery for a funnel chest takes place under general anesthesia and lasts in average 1 hour and presents minimal risks :

  • The surgeon makes a preoperative drawing on the patient's skin to mark the exact position of the implant,
  • He performs a 7-cm vertical median incision and prepares the locus to the size of the implant for a perfect stability,
  • The implant is deeply slipped into the locus under the muscle, so that it is completely invisible,
  • The surgeon closes the wall in 3 planes with absorbable intradermal stich,
  • The duration of hospitalization is 3 days maximum.

Results

The 3D custom-made technique enables excellent morphological results regardless of the sex, age or type of deformity. The PRS article shows that 80% of the patients are satisfied or very satisfied with this intervention.

Surgeon

As an experienced thoracic surgeon performing corrective pectus excavatum surgery routinely I was seeing patients who did not wish to go through such an invasive procedure with its associated period of recovery.

Patient

Before the operation I was self-conscious about taking my shirt off in public or doing any water based activities. I said to my dad I would like to see if there is anything out there that can fix my chest. After looking at various surgery’s I was more interested in just a cosmetic fix.
