[Association of posterior laryngeal cleft and atresia of the oesophagus. Two cases treated successfully (author's transl)].

Two rare cases of oesophageal atresia associated with a posterior laryngeal cleft were treated successfully: a so-called "O" interarytenoid cleft recognised secondarily to the type II atresia, not treated surgically; a so-called II cricoid cleft recognised before the treatment of type I atresia was closed in a first stage by an anterior transl-laryngeal approach. A bibliographical review is followed by a discussion of the diagnosis aspects and therapeutic possibilities of laryngeal cleft, the approach, the timing of surgery on the basis of its type and the type of oesophageal atresia.
