摘要
目的 观察腺样体肥大在不同年龄组儿童牙颌面部发育的临床表现.方法 运用计算机辅助X线头影测量技术,将68例腺样体肥大患儿(a/n≥0.71)分为A组25例(3～4岁,病程2～3年)、B组27例(5～6岁,病程2～4年)及C组16例(7～8岁,病程3～5年);同时选择20例健康儿童(3～8岁)作为对照组,行X线头影测量.结果 A、B、C三组分别与对照组比较,ANB角、上下中切牙角均减小(P＜0.01),FH-MP、Y轴角、ABS-PNS值等均增大(P＜0.01).A组与C组比较,ANB、FH-MP、Y轴角、ABS-PNS等均减小(P＜0.05),上下中切牙角增大(P＜0.05).C组与对照组比较,SNB值减小(P＜0.05),L1-NB增大(P＜0.05),其余组间比较差异无统计学意义.结论 腺样体肥大对儿童的牙颌面部发育有一定影响,且病程越长影响越明显.
Abstract
Objective To observe the clinical features of tooth maxillofacial development in children with enlarged adenoid.Methods Craniofacial morphology was studied by computerized cephalometric analysis in 68 children with adenoid hypertrophy (A/N ≥0.71).The patients were divided into three groups:group A (25 patients aged 3 to 4 years,course of 2-3 years),group B (27 patients aged 5 to 6 years,course of 2-4 years) and group C(16 patients aged 7 to 8 years,course of 3-5 years).20 healthy children were enrolled (3-8 years old) as the control group.Results Compared with the control group,the ANB angle and the up and down central incisor angle were reduced in groups A,B and C (P ＜ 0.01),while ANB,FH-MP,Y axis Angle,and ABS-equivalent PNS values were increased (P ＜ 0.01).Compared with group C,ANB,FH-MP,Y axis Angle,and ABS-PNS equivalent were decreased and the tooth angle were increased in group A (P ＜ 0.05).In group C,SNB value was decreased and L1-NB increased compared with the control group (P ＜0.05),but the two had no significantly differences between the rest groups.Conclusion Adenoid hypertrophy can result in a great impact on children's dental maxillofacial growth which is more obvious with an increase of the course.
