Inner Ear Inflammation: What Is Internal Otitis and Labyrinthitis

The morning doesn't start with coffee, but with the room slowly drifting to one side and a ringing in your ear as if an old refrigerator had been switched on nearby. This is often how inner ear inflammation makes itself known — a condition that frightens with its suddenness, but in most cases resolves on its own.

What inner ear inflammation is and how it relates to labyrinthitis

The inner ear is not only an organ of hearing but also an organ of balance: inside it there is a labyrinth — a system of fluid-filled canals — and the vestibular nerve, which sends signals to the brain. Internal otitis is a general term for inflammation in this area. When the labyrinth itself becomes inflamed, it is called labyrinthitis; when only the vestibular nerve is affected, it is called vestibular neuritis. Their symptoms are similar, but in labyrinthitis hearing is affected, whereas in neuritis it is not.

How internal otitis differs from middle and outer ear inflammation

The outer ear is the auricle and the ear canal; the middle ear is the eardrum and the three small bones that transmit sound further. Inflammation in these parts usually manifests as pain, swelling, or redness. Internal otitis manifests as dizziness, balance disturbance, sometimes hearing loss and ringing in the ear — because that is where the vestibular apparatus is located.

Internal otitis: symptoms

The most common signs of labyrinthitis: dizziness or a sensation that everything around is spinning (vertigo), unsteadiness and difficulty walking in a straight line, nausea and vomiting, hearing loss, ringing in the ears (tinnitus). Symptoms may begin suddenly — you wake up and can no longer stand steadily — and worsen by evening. They usually subside within a few days, and balance returns within 2–6 weeks, although sometimes longer.

• sudden dizziness with a sensation of spinning
• unsteadiness when walking
• nausea or vomiting
• hearing loss and ringing in the ear
• worsening of symptoms with fatigue

Why inner ear inflammation occurs

Most often the cause is viral — a cold or flu — so antibiotics usually do not help. Less commonly, the inflammation is bacterial, and in that case the doctor determines the approach.

How internal otitis is diagnosed

The doctor asks about symptoms, examines the ear with an otoscope — a device with a light — checks hearing, if necessary orders imaging studies to better see the tissues and bones, and refers to an ENT specialist. They specifically check whether hearing loss occurred suddenly: this requires an urgent consultation.

Complications and when a doctor is needed

If symptoms do not resolve within a few days or worsen, a doctor is needed. With sudden hearing loss in one ear, help is needed urgently — the person is referred to a specialist for examination and possible treatment. Long-term balance problems sometimes last for months; in such cases the doctor will refer to a specialist.

Dizziness alone is not a reason to call an ambulance; 103 or 112 — for a life-threatening condition (for example, suspected stroke). With sudden hearing loss in one ear, an urgent doctor's consultation is needed.
