Concepts on correction of the musculoaponeurotic layer in abdominoplasty

The musculoaponeurotic layer of the abdominal wall should be corrected during abdominoplasty according to the specific deformity that the patient presents with. In this article, the anatomic basis of deformities and defects of the abdominal wall is described. Different degrees of deformities secondary to pregnancy are described as well as congenital muscle malposition. These conditions should be treated in specific ways so that the most efficient correction can be achieved and no recurrence will occur. In cases of associated incisional hernias, the ''components separation'' technique can be considered for abdominal wall reconstruction and 2 alternative techniques of dissection of myoaponeurotic components are described for the correction of specific defects.
