摘　　要：目的比较学龄痉挛型脑瘫儿童与正常儿童在鼻腔共鸣方面的差异，探讨学龄痉挛型脑瘫儿童的鼻腔共鸣特征。方法对90例正常儿童（纳入正常组）及62例痉挛型脑瘫儿童（纳入脑瘫组）进行平均鼻流量（MNS）测试，将所得结果进行对比分析。结果（1）年龄因素对正常组儿童发／a／、／i／、／In／音时的MNS具有显著影响（P〈0．05），对发／u／音时的MNS无明显影响（P〉0．05）；年龄因素对脑瘫组患儿发／a／、／i／、／u／、／m／音时的MNS均无明显影响（P〉0．05）；（2）性别因素仅对正常组儿童发／i／音时的MNS具有显著影响（P〈0．05），对其它发音的MNS均无明显影响（P〉0．05）；（3）痉挛型脑瘫患儿发／a／音时的MNS显著低于正常儿童（P〈0．05），而发／i／、／u／音时的MNS显著高于正常儿童（P〈0．05）。结论随着年龄增长，正常儿童发／a／、／i／、／u／音时的MNS呈现先增后减趋势，而发／m／音时的MNS呈现逐渐增加趋势，11～13岁是学龄正常儿童鼻腔共鸣功能发育的高峰期，而痉挛型脑瘫患儿发／a／、／i／、／u／、／m／音时的MNS无相应变化趋势，整体上表现为鼻腔共鸣功能发育迟滞；学龄痉挛型脑瘫患儿较正常儿童更容易出现鼻音功能亢进等异常。Objective To characterize the nasal resonance of children with spastic cerebral palsy by compa ring it with that of ordinary school-age children. Methods The mean nasalance scores （MNSs） of 90 normal school-age children and 62 school-age children with spastic cerebral palsy were measured and compared. Results （ 1 ） Age has significant effects on the MNS of/a/, /i/ and/m/ in ordinary children, but has almost no effect on the MNS of/u/. The MNS of/a/, /i/, /u/ and/m/ in children with spastic cerebral palsy does not change with age. （2） Sex only has a significant relationship with the MNS of/i/ in ordinary children, but does not significantly predict the other MNSs. （3） The MNS of/a/ of children with spastic cerebral palsy is significantly lower than that of ordina ry children, and their MNS of/i/ and/u/ is significantly greater than those of ordinary children. Conclusions The MNS of/a/, /i/ and/u/first increases and then decreases with age in ordinary children, while the MNS of/m/ increases gradually. Children with spastic cerebral palsy did not show the same trends and demonstrated a state of retardation of nasal resonance. Children with spastic cerebral palsy are more likely to display hypernasality than ordinary children.
