Primary and secondary procedures in functional and aesthetic reconstruction of noma-associated complex central facial defects.

Background: Most defects resulting from noma involve the lateral and anterolateral aspects of the face and are often combined with severe functional deficits. A subgroup, commonly called "central noma," is composed of defects of the upper lip, maxillary soft tissues, premaxilla, nasal cartilaginous infrastructure, and soft tissues. In contrast to unilateral involvement of the face, central noma does not affect opening of the jaw; however, it results in severe mutilation, with disfiguring three-dimensional defects erasing any individual traits from a face.
