Technical modification of the Nuss operation for the correction of pectus excavatum.

Pectus excavatum is a deformity of the thoracic wall present in less than 1% of the population. Treatment is essentially surgical because of the size of the deformity. The most employed surgical options are the technique proposed by Ravitch and its variations and the technique proposed by Nuss. The first one is considered the conventional technique, while the Nuss procedure is minimally invasive and is currently receiving wide acceptance. The goal of this report is to propose 2 technical modifications to the Nuss operation regarding the position in which the patient is placed on the surgery table and the site of introduction of the optical trocar.
