Since 1975, children with cleft lip and palate living in the western part of Sweden have been treated according to a regimen of early repair of the soft palate (at the age of 6-8 months) and late hard palate closure (at about 8-9 years of age). The present paper is a longitudinal study of 15 consecutive patients whose speech development was analysed at the mean ages (years:months) of 5:3, 7:0, 8:5, and 9:7 years. Hypernasality gradually decreased over the years whereas nasal escape almost completely ceased after closure of the residual cleft. There was no glottal articulation at any age. Despite the fact that retraction of apicodental consonants decreased in frequency with age and presumably with speech therapy, it was the main problem throughout the observation period. It was presumably caused by the residual cleft in the hard palate compensating for subnormal pressure in front of the opening to the nasal cavity.
自1975年以来，瑞典西部唇腭裂患儿一直按照软腭早期修复（6至8个月龄）和硬腭晚期闭合（约8至9岁）的方案进行治疗。本文是一项对15例连续患者的纵向研究，分析了他们在平均年龄（岁：月）5:3、7:0、8:5和9:7岁时的言语发展情况。多年来，高鼻音逐渐减轻，而在残余腭裂闭合后，鼻漏气几乎完全停止。在任何年龄都没有声门发音。尽管齿龈塞音的后缩频率随着年龄增长以及可能随着言语治疗而降低，但在整个观察期内，这都是主要问题。这可能是由于硬腭的残余腭裂补偿了鼻腔开口前方的压力不足所致。
