Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
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.
