摘　　要：【目的】研究不同胎龄早产儿的听力发育状况及听力检测的临床意义。【方法】采用瞬态耳声发射(transient evoked otoacoustic emissions,TEOAE)和脑干听觉诱发电位(auditory brainstem response,ABR),对2012年1月-2012年8月在新生儿重症监护病房(neonatal intensive care unit,NICU)和母婴同室住院的328例早产儿和9 086例足月新生儿(对照组)进行听力筛查。【结果】早产儿听力筛查的通过率明显低于足月儿(χ2=183.67,P<0.01)。且胎龄越小的早产儿,听力筛查的通过率越低。28周≤胎龄<31周35例,通过16例,通过率45.71%;31周≤胎龄<34周124例,通过81例,通过率65.32%;34周≤胎龄<37周169例,通过135例,通过率79.88%。各组通过率差异具有统计学意义(χ2=19.17,P<0.01)。【结论】早产儿是听力损失的高危人群,应重点监测,早期诊治。[Objective] To explore the clinical significance of the hearing detection on different gestational age preterm infants. [Methods] With Transient evoked otoacoustic emissions （TEOAE） and auditory brainstem response （ABR）,328 cases of premature infants hospitalized in neonatal intensive care unit（NICU） and 9 086 cases of full-term new-borns（control group） rooming in were done hearing screening from January 2012 to August 2012. [Results] Pass rate of hearing screening on the preterm infants was significantly lower than the full-term children（ χ^2=183.67 ,P〈0.01 ）. And the smaller the gestational age was, the pass rate of hearing screening was lower on preterm infants. 28 weeks≤gestational age 〈31 weeks,a total of 35 cases by 16 cases,the pass rate was 45.71% ;31 weeks≤gestational age〈34 weeks,a total of 124 cases by 81 cases,the pass rate was 65.32% ;34 weeks≤gestational age〈37 weeks,a total of 169 cases by 135 cases,the pass rate was 79.88 %. The differences were statistically significant（χ^2= 19.17, P〈0.01 ）. [Conclusion] Preterm infants are the high risk group of hearing lossing,the group should be monitored especially,diagnosed and treated early.
