Rationale:Tick infestation of the external auditory canal (EAC) constitutes <1% of all patients presenting with ear complaints. Consequently, parameters for the diagnosis and management of ticks in the EAC have not been established.Patient concerns:We report 2 cases of EAC infestation by Amblyomma testudinarium in 2 female patients, aged 12- and 72 years old.Diagnoses interventions and outcomes:In both patients, otoscopic examination revealed engorged ticks attached to the ear canal. The 12-year-old girl had a narrow EAC, necessitating slight dislodging of the tick to determine if its mouth parts were embedded in the EAC skin. The tick's mouth parts were confirmed to be free, enabling complete removal of the tick. The 72-year-old woman had a wide EAC, enabling tick removal using Hartman's forceps because the tick's mouth parts were confirmed to be free of the skin. Prophylactic tetracycline (200 mg/day) was administered to each patient for 7 days; neither showed any signs of fever or rash.Lessons:This report describes 2 patients with A testudinarium infestation of the EAC, and proposes a simple, noninvasive protocol for determining if the tick is anchored to the ear canal.

“…Ticks are very slow in action, and tend to climb onto grassy leaves in a forest to wait for the passage of animals or people, rather than outright chasing a potential host [ 2 ]. Tick bites are frequent in people attending picnics, or those with periodic exposure to plants, such as farmers [ 6 ]. Furthermore, it has been reported that ticks are often found in domestic dogs, as well as in livestock such as cattle and horses; domestic dogs can become carriers of tick vectors to humans [ 1 , 6 , 8 ].…”

“…However, in a geographical region or country like Korea, where ticks are rare, the diagnosis of a tick bite might not be readily confirmed, even when an engorged tick is discovered upon physical examination [ 4 , 5 ]. In particular, a true tick bite in humans occurs mainly in the head and neck region, on the arms and/or on the legs [ 1 , 2 , 6 ]. Tick bites rarely involve the ear canal, which makes it difficult to diagnose actual cases of tick bites in the ear canal.…”

An oval-shaped mass with a smooth surface was found in the ear canal of a 22-month-old male infant. Although the mass appeared to be almost entirely blocking the ear canal, it was successfully removed under a surgical microscope without general anesthesia at the outpatient department. Under an optical microscope with hematoxylin and eosin staining, the specimen was observed to have a cuticle with a serrated surface and a pore canal, as well as parts of the capitulum, salivary glands, muscles, midgut, and the legs. The specimen was identified as a hard tick of the family Ixodidae, based on gross and histological findings. This paper is the first report in Korea on the diagnosis and treatment of a tick bite in the ear canal.

“…Ticks have been reported to cause severe irritation, allergy, toxicosis and paralysis therefore they are global public health problem (Aktaş, 2008;Bursali et al, 2012). Ticks infesting in ears can cause laceration, ear canal abrasion or bleeding leading to otitis externa (Al-Juboori, 2013) and in some cases, canal edema and external ear hyperemia have been reported (Gökdoğan et al, 2016). Ticks are known to cause lowered productivity (Sajid et al, 2007), mortality (Niyonzema & Kiltz, 1986) and can transmit Theileria (T.) spp., Babesia (B.)…”

Ticks (Acari:Ixodoidea) are important ectoparasites infesting livestock and human populations around the globe. Ticks can cause damage directly by affecting the site of infestation, or indirectly as vectors of a wide range of protozoa, bacteria and viruses which ultimately lead to lowered productivity of livestock populations. Hyalomma is a genus of hard ticks, having more than 30 species well-adapted to hot, humid and cold climates. Habitat diversity, vector ability, and emerging problem of acaricidal resistance in enzootic regions typify this genus in various countries around the world. This paper reviews the epidemiology, associated risk factors (temperature, climate, age, sex, breed etc.), vector role, vector-pathogen association, and reported control strategies of genus Hyalomma. The various proteins in saliva of Hyalomma secreted into the blood stream of host and the prolonged attachment are responsible for the successful engorgement of female ticks in spite of host immune defense system. The various immunological approaches that have been tried by researchers in order to cause tick rejection are also discussed. In addition, the novel biological control approaches involving the use of entomo-pathogenic nematodes and Bacillus thuringiensis (B. thuringiensis) serovar thuringiensis H14; an endotoxin, for their acaricidal effect on different species and life cycle stages of Hyalomma are also presented.

Otoacariasis: demographic and clinical outcomes of patients with ticks in the ear canal

Abstract: It is very important to detect ticks in the ear canal as they act as vector of some diseases. Identifying species of ticks may help clinicians to prevent further complications associated with vector-borne diseases.
