The authors report about one case of intrinsic congenital stenosis of the trachea in a newborn. The prognosis of tracheal stenosis in infants is poor, more so when it is congenital and intrinsic, because it is often extensive and associated with other malformations, especially of the right mainstem bronchus and of the right lung. The prognosis of such extensive stenoses, for which surgery constantly resulted in death, has been improved by a new type of tracheoplasty (Kimura-Tsugawa, 1982). However, these children can only be operated with this procedure once they are through intensive care and acute respiratory distress, often in the neonatal period.

[Comparative study of temporal parameters of alaryngeal voices. Esophageal and tracheo-esophageal voices].
Recent studies have established significant acoustic and phonetic differences between tracheo-oesophageal (TE) and conventional esophageal voices (EV). 12 alaryngeal voices (2 esophageal, 6 myomucosal shunts, 4 tracheoesophageal phonatory protheses), and 7 normal laryngeal voices were recorded and analyzed. Speech timing including voicing and pauses distribution was evaluated and compared to laryngeal voices. Speakers with TE voices using pulmonary air were able to preserve the rythm and the syntactico-semantic structure of their speeches, as opposed to speakers with EV who often had to insufflate air into the esophagus and therefore had a staccato-like speech. The phonation time was quite similar in both situations, but the length and the number of pauses made the difference.
