The prevalence of reading disability was examined in 172 elementary school children with cleft lip and palate (CLP) or cleft palate only (CPO). Approximately 35 percent of the sample displayed a moderate degree of reading disability, and 17 percent of the group exhibited severe reading disability. Reading disability was more prevalent at younger ages, presumably because of peripheral speech deficits. For older children, those with CLP displayed an incidence of reading disability similar to the general population (9 percent), whereas children with CPO exhibited a much higher rate of reading disability (33 percent). There were no sex differences in the prevalence of reading disability in this sample. The study supports earlier suggestions that children with CPO may be more likely to experience general language disorders leading to long-term reading disabilities. Children with CLP appear to manifest reading problems that tend to resolve with increased age.
对172名患有唇腭裂（CLP）或仅腭裂（CPO）的小学生的阅读障碍患病率进行了调查。样本中约35%表现出中度阅读障碍，该组中17%表现出严重阅读障碍。阅读障碍在较年幼的儿童中更为普遍，可能是由于外周言语缺陷。对于年龄较大的儿童，唇腭裂儿童的阅读障碍发生率与普通人群相似（9%），而仅腭裂儿童的阅读障碍发生率则高得多（33%）。该样本中阅读障碍的患病率不存在性别差异。该研究支持了早期的观点，即仅腭裂儿童可能更易出现导致长期阅读障碍的一般语言障碍。唇腭裂儿童出现的阅读问题似乎会随着年龄增长而得到解决。
