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/nI〉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。
Objective To observe the clinical features of tooth maxillofacial development in children with enlarged ade- noid. 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 - NIP, 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.
