Pectus Excavatum treatment

AnatomikModeling's 3D custom-made silicone implants are computer-designed from a medical scan and fit perfectly to the anatomy of each patient. It is a first choice and minimally invasive solution to treat Pectus Excavatum.

Pectus Excavatum Pathology

Pectus Excavatum pathology

Pectus Excavatum is a malformation of the thorax characterised by a median or lateral depression of the sternum. Funnel chest occurs in 1 to 2% of the population. This is the most common congenital thoracic deformity with an incidence of between 1 in 300 and 1 in 10000 births. As concerns women, it can lead to breast's deformity or asymmetry. There is little or no heart and/or respiratory impact except in very specific cases. It is rather a psychological discomfort, regardless of age. Currently, only 15% of those with a chest deformity are being operated.

The 'custom-made' technology

Our computer-aided design (CAD) processes enable us, from a hospital patient scan, to create a 3D virtual copy of each patient's body and to design the implant that will perfectly fit its anatomy. The 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. We use a medical-grade polymerized silicone rubber from NuSil, registered with the FDA (Food & Drugs Administration). Not being a silicone gel, there is no risk of rupture.

Pectus Excavatum Surgery

3D implant for Pectus Excavatum

The surgery for a funnel chest takes place under general anaesthesia and lasts in average 1 hour and presents minimal risks. The surgeon prepares the locus to the size of the implant after performing a 7-cm vertical median incision. The implant is deeply slipped into the locus under the muscle, so that it is completely invisible. The closing is made in 3 planes with absorbable intradermal stich. The duration of hospitalization is 3 days.

Surgical outcomes of Pectus Excavatum

Pectus Excavatum treatment with a custom-made implant
  • Surgical outcomes with little pain: the pain is treated with simple analgesics.
  • No post-operative care: the stitches are resorbable, no drain, only a dressing for 8 days and a compression bra to wear from discharge for 1 month.
  • Follow‑up consultation after 8 days with possible puncture of seroma
  • Sick leave for 15 days and sports restriction for 3 months.

Assets

Computer-aided designing (CAD) for custom-made implantable prosthesis presents several advantages for the patient suffering concave chest, as it perfectly fits the receiver’s site

Setting up the implant is made easier. perfect stability of the implant: sub-muscular set up.
The aesthetic result is refined, the edges of the prosthesis are invisible.
Definitive implant : latest-generation polymerised silicone (silicone rubber, no silicone gel).
The post-operative outcomes are a lot less important than with orthopaedic techniques (Ravitch or Nuss): only one surgical procedure, 1 hour of surgery,1 to 3 days of hospitalization
The risks of haematomas are low: no drain.
Surgical outcomes with little pain: the pain is treated with simple analgesics
Rapid resumption of activity : 15 days to work and 3 months to make sport
The management of complex cases is made easier: Ravitch technique, Nuss procedure, lateralised or low deep pectus, redo surgery on the implanted breast prosthesis…

Results

  • I have been suffering since childhood from Pectus Excavatum which was pretty deep. I was never satisfied with my body and I wasn’t confident at all although the deep was hidden under the bra.I searched a lot and I found 3D-custom Implant technique. It took me about one year to decide and finally I did it last week. I had implant surgery with a great thoracic surgeon in London in October 2018.

    I just had little pain in sudden movements. I will go back to work within few days.

    I have seen the result and I am fully satisfied with my operation. I wish I made this decision earlier and didn’t suffer whole these years.

    Testimony of Hoda, 37 yo, London (UK)
  • 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. Following a visit to Prof Chavoin and the team at AnatomikModeling and detailed training in the non-corrective pectus implant technique I performed my first pectus implant at the beginning of 2017 and have gone on to perform many more procedures using the AnatomikModeling's 3D custom implant and the insertion techniques described by Prof Chavoin. Once the implant is precisely mapped using 3D CT modelling techniques the implant is expertly manufactured by Sebbin who create a high-quality custom-made implant. I have been most impressed by the simplicity of the surgical approach, the excellent custom fitting of the implant and the excellent outcomes. Recovery is so quick with patients returning to work within days of surgery and back to the gym within several weeks of surgery. It has added another dimension to my pectus surgical practice!
