Abstract

Otoacariasis is a rare condition characterized by ticks and mites in the ear canal. Human otoacariasis remains underrepresented in literature as otoacariasis is more common in animals. Systemic diseases being transmitted by these arachnids pave the way for potential complications. This case series sheds light on this uncommon condition by highlighting the diverse symptomatology and difficulties in diagnosis and treatment. Three different presentations highlight the diversity of this condition. A 40-year-old male exhibited itching and tinnitus, revealing a mite on the tympanic membrane on otoscopy. A 35-year-old female with persistent itching and tinnitus showed multiple whitish mites on examination. A 50-year-old female complained of ear pain and was found to have a tick attached to the external auditory canal. The relevance and rarity of human otoacariasis are highlighted in this study, thereby encouraging caution in situations of earache. We aim to increase clinician awareness about this condition and the necessary interventions required by conducting a thorough literature review.
