How to determine if it is otitis or a tick? - briefly
Check the ear for signs of infection—pain, fluid discharge, redness, and swelling of the canal—because these indicate otitis, whereas a tick presents as a small, attached arachnid with a visible body and mouthparts, often surrounded by a localized rash. If a live parasite is visible on the skin rather than internal ear symptoms, the condition is a tick attachment.

How to determine if it is otitis or a tick? - in detail
When a patient presents with ear discomfort, the clinician must separate a middle‑ear or external‑ear infection from a parasitic attachment. The two conditions share pain and itching but differ in onset, visual clues, and required management.
Clinical clues

Pain pattern – Infection usually causes a deep, constant ache that worsens with pressure changes (e.g., chewing, altitude). Tick attachment produces sharp, localized pruritus that may intensify when the animal moves.
Ear canal appearance – Otitis often shows erythema, edema, and purulent discharge. A tick is visible as a dark, engorged body firmly attached to the skin, sometimes with a clear surrounding halo.
Systemic signs – Fever, malaise, and lymphadenopathy accompany bacterial or fungal ear infections. Tick bites may be followed by a rash, fever, or flu‑like symptoms only after several days, reflecting pathogen transmission.
History – Recent outdoor activity in tick‑infested areas points toward parasitism. Recent swimming, ear cleaning, or upper‑respiratory infection suggests an inflammatory process.

Diagnostic steps

Otoscopy – Examine the canal with a speculum and light. Look for:

Inflamed mucosa, fluid levels, or perforation (infection).
An intact arthropod attached to the canal wall or tympanic membrane (tick).

Palpation – Gently press around the suspected area. A tick will be firmly anchored and may twitch when disturbed; inflamed tissue feels tender but not attached.
Microscopy – If the visual field is limited, use a handheld dermatoscope or microscope to confirm the organism’s morphology (segmented body, legs, mouthparts).
Laboratory tests – For persistent otitis, obtain a swab for culture and sensitivity. If tick exposure is confirmed, consider serology for Lyme disease, Rocky Mountain spotted fever, or other tick‑borne illnesses, depending on geographic prevalence.

Management

If infection is identified

Clean the canal with a gentle irrigant.
Administer topical antibiotics (e.g., ciprofloxacin‑dexamethasone drops) or oral agents for severe cases.
Provide analgesia and advise avoidance of water exposure until resolution.

If a tick is present

Use fine‑point tweezers to grasp the tick as close to the skin as possible; pull upward with steady, even pressure.
Disinfect the area with antiseptic after removal.
Observe the bite site for signs of infection; prescribe prophylactic antibiotics only if high‑risk pathogens are endemic.
Initiate appropriate antimicrobial therapy if serology confirms disease transmission.

Prevention

Encourage routine ear inspections after outdoor activities.
Use insect‑repellent clothing and tick‑checks on pets.
Maintain ear hygiene without aggressive cleaning, which can damage the canal and predispose to infection.

By correlating symptom patterns, visual examination, and targeted tests, a practitioner can reliably differentiate an ear infection from a tick attachment and apply the correct therapeutic protocol.
