Abstract
Objective Analyze the result of air-and bone-conduction evoked click-ABR in children with congenital external auditory canal atresia;Assess the relationship between age and threshold of air-and bone-conduction evoked click-ABR.Methods Step 1 Sample 46 children with congenital malformation of external ear (,aged 0~3 years old from January 2013 to December 2013.Step 2 Split the cases into three groups by age (0,1,2~3).Exam respectively with air-and bone conduction ABR.Step 3 Analyze the result statistical y.Results The data of the air-conduction reaction threshold is (80.52±3.23)dBnHL of the children aged 0~1;(78.3±9.32)dBnHL of the children aged1-2;(72.35±7.65)dBnHL of the children aged 2~3. the same age groups,the data of the bone-conduction reaction threshold is(9.87±3.23)dBnHL of the children aged 0~1;(9.63±2.35)dBnHL of the children aged1-2;(9.67+2.4)dBnHL of the children aged 2~3;.and the fol owing is the data of the air-conduction ABR v wave latency under 30 dBnHL stimulation:children of 0~1(7.85±0.33)ms;children of 1~2(7.53±0.32)ms;children of 2~3(7.23±0.25)ms.And the bone-conduction ABR v wave latency under 100dBn HL stimulation has the fol owing data:(6.87±0.23)ms of the children aged 0~1;and children of 1-2 (6.34+0.3)ms;children of 2-3 (5.58±0.25)ms.Air conduction ABR threshold increases with age and bone conduction ABR threshold is not af ected by the change of age. Conclusion Value of Bone conduction ABR threshold is not statistical y cor elated to the age of patience and thus can be used to assess the patience's hearing.关键词
