A notch is defined as the frequency point at which hearing loss is greater than 15 dB when compared to one octave above and below. C3 dip or 1 kHz notch is rarely seen and not much information is known about the clinical profile of such condition. The aim of this case report is to highlight the audiological profile of a case with 1kHz notch and discuss the possible causes for the same. Case A (16 yrs) was referred with a complaint of hearing loss and speech understanding difficulty specially at school. The teen had taken multiple medications for several health related issues like malaria, appendicitis and the understanding difficulty was evident during this period. Detailed audiological evaluation revealed a significant C3 dip in the right ear and normal hearing sensitivity in the left ear. Evidences from literature suggests strong correlation between drugs like Cefotetan, cefotaime, piperacillin, ampicillin (appendicitis treatment) and chloroquine (malaria) and hearing loss. Hence, we concluded that the possible cause of 1khz is ototoxic medication. [ABSTRACT FROM AUTHOR] |
