The prevalence of impacted earwax is different across the world. In the United Kingdom 2 to 6% of the population have cerumen that is impacted. In America 3.6% of emergency visits caused by ear issues were due to impacted cerumen. In Brazil 8.4–13.7% of the population have impacted cerumen. [46]
The removal of cerumen is also an important step in the treatment of otitis in small animals. [12] Veterinary cerumenolytics possess different potencies. Diocytl sodium sulfosuccinate (DOSS), dioctyl calcium sulfosuccinate , and urea or carbamide peroxide are considered to be potent veterinary cerumenolytics.
