Surgical correction of the pectus excavatum has been shown to significantly improve cardiovascular function; there is inconclusive evidence so far as to whether it might also improve pulmonary function. One of the most popular techniques for repair of pectus excavatum today is the minimally invasive operation, also known as MIRPE or Nuss technique. Magnetic mini-mover procedure
The magnetic mini-mover procedure (3MP) is a minimally invasive procedure used to correct pectus excavatum by using two magnets to realign the sternum with the rest of the chest and ribcage. One magnet is inserted 1 cm into the patients body on the lower end of the sternum, the other is placed externally onto a custom fitted brace. These two magnets generate around 0.04 tesla (T) in order to slowly move the sternum outwards over a number of years. The maximum magnetic field that can be applied to the body safely is around 4 T, making this technique safe from a magnetic viewpoint. The 3MP techniques main advantages are that it is more cost-effective than major surgical approaches such as the Nuss procedure and it is considerably less painful postoperatively. Its effectiveness is limited to younger children in early- to mid-puberty because older individuals have less compliant (flexible) chest walls. One potential adverse interaction with other medical devices is possible inactivation of artificial pacemakers if present. Ravitch technique
The Ravitch technique is an invasive surgery that was introduced in 1949 and developed in the 1950s.
