A 52-year-old Korean woman who complained of impaired hearing and tinnitus of the left ear was diagnosed with an aberrant internal carotid artery (ICA) in the middle ear using a temporal bone high resolution CT (HRCT) scan. Upon otoscopic examination, her left eardrum was found to be in contact with a mass in the middle ear cavity. Upon audiometric evaluation, a mild conductive hearing impairment was documented, and a discrepancy in the results of otoacoustic emissions (OAEs) was found for the left ear. This case report studies the aberrant ICA in the middle ear that revealed abnormal OAE findings.
BACKGROUND: Our objectives were to describe the frequency and determine risk factors for hearing deterioration following pediatric stem cell transplantation (SCT). METHODS: In this prospective cohort study, we performed pure tone audiometry and measured otoacoustic emissions (OAE) prior to and following SCT. Worse hearing was considered deterioration in either audiometry or OAE. RESULTS: Between October 2000 and November 2002, 45 informative audiometry or OAE results were obtained. Hearing deteriorated following SCT in 20/45 (44%) of these children. Those with worse hearing following SCT were more likely to have neuroblastoma (odds ratio [OR] 16.0 [95% CI 1.8, 143.2; P = 0.003]), receive carboplatin conditioning (OR 7.7 [95% CI 1.4, 41.9; P = 0.01]), have abnormal baseline hearing (OR 5.1 [95% CI 1.3, 19.5; P = 0.02]), and have higher baseline serum creatinine (OR for every increase of 5 micromol/L of serum creatinine of 1.5 [95% CI 1.03, 2.1; P = 0.03]). CONCLUSION: Many children who undergo SCT will have deterioration in hearing following SCT. A high-risk group of children can be delineated who may benefit from more intensive audiological monitoring following SCT.
An objective screening method for assessment of inner ear function of babies and small children can be carried out by measuring TEOAE and DPOAE. In particular, TEOAE can be used as a cheap and quick method to determine, with very high sensitivity and moderate specificity, whether middle to severe peripheral hearing impairment is present. In order to assess the threshold more precisely, the click-BERA is routinely used. We present a case report of a 6 year old girl with regular TEOAE and DPOAE, and who also had bilateral normal thresholds in the click-BERA. With subjective audiometry, the girl could be diagnosed having bilateral mesocochlear hearing impairment (so called cookie-bite audiogram) ranging at 40-45 dB. The child was helped considerably by fitting of hearing aids bilaterally. In order to determine the auditory ability of children and to provide adequate care, subjective as well as objective tests should be used.
