[Maxillofacial reflection of choanal atresia. Apropos 11 cases]

The authors study the maxillofacial repercussions of choanal imperforation based upon 11 cases (8 unilateral and 3 bilateral). Skeletal abnormalities are defined using teleradiographic and tomographic techniques. The origin of these abnormalities is sought: malformations, deformities or sequelae of surgical treatment.
