title: [Muscle cheilomeso-ethmoidoplasty. A new surgical approach to treatment of labiomaxillary clefts].
abstract: Recent advances in our knowledge of the role of the ectomesenchyme in facial organogenesis, and the biology of fetal and infant cephalic development, supply valid arguments for the application of new principles in cheiloplasty for labial or labiomaxillary clefts. Instead of cutaneoplasty alone, the procedure involves anatomically selective muscle reconstruction of the nasolabial confines, a structure that is predominantly muscular. The alar portion of the cartilaginous mesethmoid ensures support of the nasolabial head of the orbicularis of the lip, and reconstitutes the anterior nasal vestibule by supplying the transverse muscle. Cheilomeso-ethmoidoplasty of the transverse and nasolabial muscles of the orbicularis of the upper lip is therefore as totally valid procedure.
