To examine the implications of nasal substitutions in the early words of toddlers with cleft palate.
Retrospective.
Thirty-four toddlers with nonsyndromic cleft palate and 20 noncleft toddlers, followed from ages 13 to 39 months.
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.
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.
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.
研究腭裂幼儿早期言语中鼻化替代的影响。
回顾性研究。
34名非综合征性腭裂幼儿和20名非腭裂幼儿，随访年龄为13至39个月。
比较两组幼儿早期言语中出现鼻化替代的百分比。还检查了腭裂修复术后出现鼻化替代且后来疑似有腭咽功能障碍（VPD）的幼儿百分比。
腭裂组中76%（n = 26）的幼儿和非腭裂组中35%（n = 7）的幼儿在其早期言语中的一个或多个单词上出现了鼻化替代。早期言语中出现鼻化替代的腭裂幼儿中，只有38%（10/26）后来被诊断为有中度至重度高鼻音并疑似VPD。
腭裂修复术后出现鼻化替代并不总是VPD的早期迹象。有腭裂和无腭裂儿童的早期词汇中均存在这些替代现象。
