Abstract:
OBJECTIVE:To investigate the current situation of early diagnosis and intervention in 0-9 months old infants with hearing loss and analysis factors that will affect early diagnosis and intervention.
METHOD:One hundred and eighty-six infants referred to the West China hospital from February 2014 to September 2014 were included. All 186 children were referred due to the fact that either they failed infant hearing screening or outer ear malformation. Early diagnosis and/or intervention were performed on those 186 children and their records of early diagnosis and intervention were analyzed.
RESULT:Among the 186 infants, 167 (89.8%) were diagnosed with an average age at (4.0 ± 1.4) months. Among the 167 infants with final diagnosis, there were 31 (18.6%) infants diagnosed as conductive hearing loss (CHL), and 99 cases (59.3%) diagnosed as sensorineural hearing loss (SNHL), among whom, there were 75 (44.9%) bilateral SNHL and 24 (14.4%) unilateral SNHL. There were 2 cases (1.20%) with SNHL on one side and atresia on the other side. 5 (2.99%) of all conductive hearing loss cases with unilateral atresia and 2 cases with auditory neuropathy (AN) were found. 33 infants (19.8%) were found to have normal hearing. 30.7% (23/75) infants diagnosed as bilateral SNHL and 8.3% (2/24) infants diagnosed as unilateral SNHL were fitted with hearing aids. The fitting rate in infants with bilateral SNHL with mild, moderate, severe to profound degrees were 0 (0/23), 24.0% (6/25), 66.7% (6/9), 61.1% (11/18) respectively. The average intervention age was (5.0 ± 2.1) months.
CONCLUSION:Although the early diagnosis and intervention situation in this study are very close to international standard, there are still infants without final diagnosis and infants with hearing loss without hearing aid fitting. Further studies and efforts to promote early diagnosis and intervention in infants with hearing loss are needed.
