BACKGROUND: Hoarse or asthenic voice is frequently associated with various pediatric @entity299 . The aim of this study was to investigate the changes in voice physiology after surgical correction in @entity1 with @entity299 . METHODS: We performed voice analysis using induced crying of 40 @entity1 with @entity299 ( @entity299 ) such as @entity1757 ( @entity1757 ), @entity2461 ( @entity2461 ), and @entity118 ( @entity118 ; 31 @entity1 , 24 @entity1 ; mean age, 11    8.9 months). Cries were serially recorded immediately prior to operation, then 1 week, and 1 month after surgical correction, respectively. Acoustic parameters, fundamental frequency (F0 ), duration of cry, noise to harmonic ratio (NHR), jitter, and shimmer, were extracted using Multi-Dimensional Voice Program    (MDVP) a computerized speech analysis system. Cries were compared with 30 normal healthy @entity1 of corresponding age. RESULTS: Among the 25 @entity1 with @entity1757 , cry duration, jitter, and shimmer improved after the operation (P < 0.05). F0 and NHR, however, were not significantly different. F0 in @entity1 with @entity2461 improved, but was not statistically significant. The duration of cry, jitter, shimmer, and NHR improved in the @entity2461 group (P < 0.05). The jitter and shimmer parameters improved significantly (P < 0.05), but F0 , cry duration, and NHR in @entity1 with @entity118 did not show any significant changes. CONCLUSIONS: Deviated voice patterns in pediatric @entity1 with @entity299 can normalize after surgical correction. In addition, non-invasive analysis such as MDVP can be used to identify vocal @entity912 , even in the early postoperative period.
