Purpose This study investigated the influence of the cleft type on the appearance of hypernasality after surgical maxillary advancement (MA). Methods Nasality was determined by measurement of nasalance (acoustic correlate of nasality) by nasometry. The study involved analysis of the nasalance scores of 17 individuals with isolated cleft palate (CP), 118 with unilateral cleft lip and palate (UCLP) and 69 with bilateral cleft lip and palate (BCLP), of both sexes, aged 18 to 28 years, after MA. Only individuals with normal nasalance scores indicating balanced resonance before MA were included in this study. Nasometry was performed 3 days before and 15 months after MA, on average. The proportion of patients who presented nasalance scores indicating hypernasality after surgery was calculated by the ANOVA test, and comparison among the different cleft types was evaluated by the chi-square test (p < 0.05). Results No significant difference was found in the proportions of individuals with hypernasality among the cleft types. Conclusion Nasometry showed that the appearance of hypernasality after MA in individuals with cleft palate with or without cleft lip occurred in similar proportions, regardless of the cleft type.
目的 本研究调查腭裂类型对上颌骨前移术（MA）后高鼻音表现的影响。方法 通过鼻音计测量鼻声反射（鼻音的声学相关指标）来确定鼻音情况。该研究分析了17例单纯腭裂（CP）、118例单侧唇腭裂（UCLP）和69例双侧唇腭裂（BCLP）患者在MA术后的鼻声反射分数，患者年龄在18至28岁之间，性别不限。本研究仅纳入MA术前鼻声反射分数正常、共鸣平衡的个体。平均在MA术前3天和术后15个月进行鼻音计测量。通过方差分析计算术后出现高鼻音鼻声反射分数的患者比例，并通过卡方检验评估不同腭裂类型之间的差异（p < 0.05）。结果 不同腭裂类型中出现高鼻音的个体比例无显著差异。结论 鼻音计测量显示，无论腭裂类型如何，有或没有唇裂的腭裂患者在MA术后出现高鼻音的比例相似。
