To evaluate the role of distortion product otoacoustic emissions (DPOAE) results in children with middle-ear effusion before and after ventilation tube insertion.
The study was conducted between the September 2007 and May 2008 at the Otolaryngology Clinic diagnosed with middle-ear effusion. A prospective study was carried out 30 patient (18 males, 12 females; mean age 8.6 years; range 6 to 15 years) and a total of 41 ears with middle-ear effusion. A total of 30 ears of 15 volunteers healthy control group (8 males, 7 females; mean age 7.8 years; range 5 to 15) included in the study. All children listed for appropriate surgery had a pre- and postoperative (four week after) tympanometry, pure tone audiometry and DPOAE recorded. A comparison was made between control group DPOAE value and pre- and postoperative DPOAE value of patient.
Preoperatively, 41 ears had an abnormal tympanometry of which 80% had absent DPOAE. After four week all postoperative patients with surgery had 92.6% a normal DPOAE. Control group of 29/30 ears had a normal (96.7%) DPOAE.
Patients with otitis media with effusion measured preoperative DPOAE, postoperative after one month all patients with grommets had a more DPOAE value comparison with preoperative, but less for control group.
评估畸变产物耳声发射（DPOAE）结果在中耳积液患儿鼓膜置管前后的作用。
该研究于2007年9月至2008年5月在诊断为中耳积液的耳鼻喉科诊所进行。对30例患者（18例男性，12例女性；平均年龄8.6岁；年龄范围6至15岁）共41只中耳积液耳进行了前瞻性研究。15名志愿者健康对照组（8例男性，7例女性；平均年龄7.8岁；年龄范围5至15岁）的30只耳纳入研究。所有计划进行适当手术的儿童均在术前及术后（四周后）进行了鼓室图、纯音听力测定和DPOAE记录。对对照组的DPOAE值与患者术前及术后的DPOAE值进行了比较。
术前，41只耳鼓室图异常，其中80%的耳DPOAE消失。四周后，所有接受手术的术后患者92.6%的耳DPOAE正常。对照组30只耳中有29只（96.7%）耳DPOAE正常。
中耳积液患者术前测量DPOAE，术后一个月所有鼓膜置管患者的DPOAE值与术前相比有所增加，但对照组增加较少。
