【摘要】 对56例腭裂患儿和50例正常儿童的中耳功能进行对比评价。年龄5～14岁。均进行耳科常规及声阻抗检查,发现腭裂患儿中耳静态压力与声顺值,声镫骨肌反射引出率都低于正常儿童。其咽鼓管功能不良,调节中耳压力的能力差,通过吞咽来主动开放咽鼓管的功能受限,故腭裂患儿的合理治疗需要多科医生的共同配合。更多还原

【Abstract】 Middle ear problems in patients with cleft palate have for a long time received insufficient attention.The present study was designed to evaluate middle ear function in 56 children with cleft palate and in a control group of 50 children without cleft palate.The age ranging between 5 and 14 years was similar in both groups.All children underwent routine otoscopic examinations of ear,nose and throat,and were also examined using the Madsen acoustic impedance audiometer.Four major parameters (static com- pliance,middle ear pressure,acoustic stapedius reflex and Eustachian tube function) were analyzed.It was found that the negative middle ear pressures were higher and the static compliance,which reflected the e- lasticity of the conducting mechanism of the middle ear,was poorer in children with cleft palate than in the controls.The proportion of children with cleft palate who showed the presence of the acoustic stapedius re- flex was also lower than in the control children.Children with cleft palate have a limited ability to actively open the Eustachian tube by swallowing,as evidenced by a poor ability to equilibrate applied positive or negative middle ear pressure.A multidisciplinary approach should be adopted for the complete overall reha- bilitation of children with cleft palate.Plastic surgeons to whom most of the treatment is entrusted shoule be concerned not only with achieving palatal function and acceptable speech,but also with the various other problems associated with cleft palate,especially those affecting the middle ear.更多还原
