[Labio-maxillary and velopalatine clefts. Clinical and therapeutic aspects].

Harelip, facial cleft and cleft palate are frequent accidents of facial development. There is nothing special with their embryological mechanism, but their consequences concerning the future anatomy of the oral and nasal cavities are impressive. Owing to a better understanding of facial embryology and of the anatomical repercussions of the clefts, satisfactory morphological results can be obtained by surgical lip repair performed with an ever increasing precision.
