The surgery is performed under general anesthesia and takes about an hour. The surgeon makes an incision of approximately seven centimetres, prepares the customised space in the chest, inserts the implant deep beneath the muscle, then closes the incision. Post-operative hospitalization is typically around three days.The recovery after the surgery typically requires only mild pain relief. Post-operatively, a surgical dressing is required for several days and compression vest for a month following the procedure. A check-up appointment is carried out after a week for puncture of seroma. If the surgery has minimal complications, the patient can resume normal activities quickly, returning to work after 15 days and participating in any sporting activities after three months. Lipofilling
The "lipofilling" technique consists of sucking fat from the patient using a syringe with a large gauge needle (usually from the abdomen or the outer thighs), then after centrifugation, the fat cells are re-injected beneath the skin into whichever hollow it is needed to fill. This technique is primarily used to correct small defects which may persist after conventional surgical treatment. Epidemiology
Pectus excavatum occurs in an estimated 1 in 150 to 1 in 1000 births, with male predominance (male-to-female ratio of 3:1). In 35% to 45% of cases family members are affected. Etymology
Pectus excavatum is from Latin meaning hollowed chest. It is sometimes referred to as sunken chest syndrome, cobblers chest or funnel chest. Society
American Olympic swimmer Cody Miller (born 1992) opted not to have treatment for pectus excavatum, even though it limited his lung capacity.
Kyphoscoliosis is excluded by diagnostic imaging of the spine, wherein pectus excavatum the spine usually appears normal in structure. Treatment
Pectus excavatum requires no corrective procedures in mild cases. Treatment of severe cases can involve either invasive or non-invasive techniques or a combination of both. Before an operation proceeds several tests are usually performed. These include, but are not limited to, a CT scan, pulmonary function tests, and cardiology exams (such as auscultation and ECGs). After a CT scan is taken, the Haller index is measured. The patients Haller is calculated by obtaining the ratio of the transverse diameter (the horizontal distance of the inside of the ribcage) and the anteroposterior diameter (the shortest distance between the vertebrae and sternum). A Haller Index of greater than 3.25 is generally considered severe, while normal chest has an index of 2.5. The cardiopulmonary tests are used to determine the lung capacity and to check for heart murmurs. Conservative treatment
The chest wall is elastic, gradually stiffening with age. Non-surgical treatments have been developed that aim at gradually alleviating the pectus excavatum condition, making use of the elasticity of the chest wall, including the costal cartilages, in particular in young cases. Exercise
Physical exercise  has an important role in conservative pectus excavatum treatment though is not seen as a means to resolve the condition on its own.
