A Bicenter Retrospective Study Of Human Otoacariasis in Kerala

Area of Science:

• Medical Entomology
• Public Health
• Otology

Background:

• Otoacariasis, the infestation of the human ear canal by ticks or mites, presents a significant public health concern due to potential complications.
• Understanding the epidemiology and clinical characteristics of otoacariasis is crucial for effective management, particularly in underserved regions.

Purpose of the Study:

• To investigate the incidence, clinical presentation, and treatment outcomes of otoacariasis in rural southern India.
• To identify common symptoms and effective removal interventions for human ear canal infestations.

Main Methods:

• A retrospective analysis was conducted on 46 patients diagnosed with otoacariasis in two hospitals in Kerala, India.
• Data collected included patient demographics, symptomatology, location of infestation within the ear canal, and the interventions used for tick or mite removal.

Main Results:

• The study included 46 patients, with 63% being male.
• The most frequent symptoms reported were ear discharge (37%) and ear pain (23.9%).
• Glycerine application followed by ear syringing was identified as the most effective method for tick and mite removal.

Conclusions:

• Prompt identification and removal of ticks or mites from the ear canal are essential to avert potential complications.
• Raising awareness through educational campaigns and enhancing healthcare provider knowledge are vital strategies to reduce the risks associated with otoacariasis in rural communities.
