To assess the influence of nasal adenoidal hypertrophy (AH) in children on the mandibular growth pattern.
The patients were divided to two groups aged from 3 to 12 years. In the AH group (30 children), the cases who had symptom of NAO for more than two years and A/N > or = 0.71 (the adenoids/nasopharynx according to the cephalometry) were selected. In the control group (28 children), the cases who had no symptom of NAO and A/N < or = 0.60 were selected. All data of acoustic rhinometry (AR) and cephalometry were analyzed.
Compared with the controls, the total nasal airway resistance (TNAR) was significant increased (P < 0.01), the bilateria nasal cavity minimal cross sectional area (MCSA) was significant decreased (P < 0.01), and the nasopharyngeal volume (NPV) was significant decreased (P < 0.01). There were significant differences between the AH group and the controls in TNAR, NPV and MCSA. Comparing with the controls,the children with AH showed apparently vertical growth pattern, and larger gonion and retrusion chin. There was positive correlation between NPV and FH ratio.
It indicated that AH might be one of the factors related to the difference of craniofacial morphology, especially of the mandibular growth pattern.
评估儿童鼻腺样体肥大（AH）对下颌生长模式的影响。
将3至12岁的患者分为两组。AH组（30名儿童）选取有鼻气道阻塞（NAO）症状超过两年且腺样体/鼻咽比值（A/N）≥0.71（根据头影测量法）的病例。对照组（28名儿童）选取无NAO症状且A/N≤0.60的病例。对所有鼻声反射（AR）和头影测量数据进行分析。
与对照组相比，总鼻气道阻力（TNAR）显著增加（P<0.01），双侧鼻腔最小横截面积（MCSA）显著减小（P<0.01），鼻咽容积（NPV）显著减小（P<0.01）。AH组与对照组在TNAR、NPV和MCSA方面存在显著差异。与对照组相比，AH患儿表现出明显的垂直生长模式，下颌角较大且颏部后缩。NPV与FH比值之间存在正相关。
表明AH可能是与颅面形态差异，尤其是下颌生长模式差异相关的因素之一。
