Objective: To examine the implications of nasal substitutions in the early words of toddlers with cleft palate. Design: Retrospective. Patients: Thirty-four toddlers with nonsyndromic cleft palate and 20 noncleft toddlers, followed from ages 13 to 39 months. Main Outcome Measures: The groups were compared for the percentage of toddlers who produced nasal substitutions in their early words. The percentage of toddlers with repaired cleft palate who produced nasal substitutions and were later suspected of having velopharyngeal dysfunction (VPD) was also examined. Results: Seventy-six percent of the toddlers in the cleft group (n = 26) and 35% of toddlers in the noncleft group (n = 7) produced nasal substitutions on one or more of their early words. Only 38% (10/26) of the toddlers with cleft palate who produced nasal substitutions in their early words were later diagnosed as having moderate-severe hypernasality and suspected VPD. Conclusions: The presence of nasal substitutions following palatal surgery was not always an early sign of VPD. These substitutions were present in the early lexicon of children with and without cleft palate.
