摘　　要：目的:探讨儿童腺样体肥大对下颌骨发育的影响。方法:病史大于2年、A/N≥0.71伴腺样体肥大者(腺样体肥大组)共30例,无鼻病史、A/N≤0.60为对照组共28例,对两组儿童的声反射鼻测量和X线头颅测量指标进行分析。结果:声反射鼻测量显示腺样体肥大组患儿鼻气道阻力明显大于对照组(P<0.01),鼻腔最小横截面积明显小于对照组(P<0.01),鼻咽腔容积明显小于对照组(P<0.01);头颅测量显示腺样体肥大组儿童面部形态呈明显的垂直向生长,下颌平面变斜,下颌角变大;直线相关分析显示鼻咽腔容积与面高比例明显相关(r=0.390,P<0.05)。结论:腺样体肥大可影响儿童的颌面发育,主要是对下颌的位置和形态有影响。Objective： To assess the influence of nasal adenoidal hypertrophy（AH）in children on the mandibu- lar growth pattern. Method：The patients were divided to two groups aged from 3 to 12 years. In tile AH group （30 children）, the cases who bad symptom of NAO for more than two years and A/N≥0.71（the adenoids/nasaphary nx according to the cepha]ometry） were selected. In the control group （28 children）, the cases who had no symp- tom of NAO and A/N≤0. 60 were selected. All data of acoustic rhinometry （AR） and cepbalometry were ana- lyzed. Result： Compared with the controls, the total nasal airway resistance （TNAR） was significant increased（ P〈~. 0.01） ,the bilalerior 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 be- tween 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 correla tion between NPV and FH ratio. Conclusion： It indicated that AH might be one of the factors related to the differ- ence of craniofacial morphology, especially of the mandibular growth pattern.
