Theoretical principles and technique of functional closure of the lip and nasal aperture

Since many approaches to the closure of the cleft lip have not satisfied the hopes placed into them, the author has gone back to the principles stated by Veau (1938). His anatomical findings are presented. They form the basis of his technique of functional closure of the lip and nasal aperture: Careful dissection of all muscles involved, anatomical repositioning of all structures of the lip and the nasal entrance, and wide subperiosteal dissection. Careful reconstruction of a normal anatomical situation leads not only to better appearance and good mobility of the area concerned, but also to an enhanced growth of the underlying bony structures. Primary osteoplasty has been used, but does not seem to be necessary. The early results of this technique are very satisfying, however, later re-evaluation has to be made.
