Summary

A case of Ixodes ovatus tick infestation in the ear canal was successfully treated. The novel removal method involved excising the tick abdomen and suctioning fluids, followed by complete removal.

Area of Science:

  • Otorhinolaryngology
  • Parasitology
  • Veterinary Medicine

Background:

  • External auditory canal (EAC) infestations are uncommon but can cause significant discomfort.
  • Tick bites, particularly from Ixodes species, pose risks of disease transmission and local reactions.
  • Canine contact is a potential source for zoonotic tick exposure.

Observation:

  • A patient presented with ear fullness and pruritus following direct contact with a dog.
  • Physical examination revealed an Ixodes ovatus tick lodged within the external auditory canal.
  • Symptoms were attributed to the presence and potential feeding activity of the tick.

Findings:

  • A two-stage removal technique was employed: initial excision of the tick's abdomen and aspiration of its body fluids.

Related Experiment Videos

  • The remaining tick body was successfully removed atraumatically three days post-initial intervention.
  • Histopathological examination confirmed the presence of Ixodes ovatus, with no signs of secondary infection or significant tissue damage.

    • Implications:

    • This case highlights a rare presentation of tick infestation in the EAC.
    • The described removal method offers a potentially effective and safe approach for managing similar cases.
    • Awareness of zoonotic risks from pet contact is crucial for preventing such occurrences.
