The quality of the results of laryngotracheoplasties is clear evidence of the progress made in the treatment of stenoses involving the larynx and the trachea in children. the surgeon is no longer limited to helping the child breath correctly via the natural airways but can also concentrate on phonatrics since dysphonia is frequent after laryngotracheoplasty. Vocal production of 23 children who had undergone surgery for laryngotracheal stenosis was evaluated subjectively by a panel of listeners and objectively on the basis of the pitch and intensity of the voice, rate of speech and maximal time of phonation. In 11 children over the age of 5 years, assisted assessment of the voice completed the study. In 69.5% of the cases, the voice was subjectively considered to be satisfactory. Voice was considered clear in 52% of the cases. Speech flow was impaired in 39% due to frequent breath taking. Objective parameters revealed that pitch was slightly impaired (256 Hz) with a tendancy to normalize near puberty. The intensity of the voice (77 dB) and mean maximum phonation time (7 s) decreased. The phonotary quotient (270 ml/sec), jitter (1.4%) and leakage of the glottis (2.02 cm3/dB/s) were slightly above the normal range. The spectra of the voices were richly furnished with harmonics up to about 1 000 Hz above which air noises increased. An attempt was made to correlate the analysis of the voice with the characteristics of the stenosis and with the therapeutic methods used. The results would suggest the iatrogenic nature of prolonged canulation and of increasing the size the size of the posterior cricoid.(ABSTRACT TRUNCATED AT 250 WORDS)
