Overview

A ruptured eardrum (tympanic membrane perforation) is a hole or tear in the thin tissue that separates your ear canal from your middle ear (eardrum).

A ruptured eardrum can result in hearing loss. It can also make your middle ear vulnerable to infections.

A ruptured eardrum usually heals within a few weeks without treatment. But sometimes it requires a patch or surgical repair to heal.

Symptoms

Signs and symptoms of a ruptured eardrum may include:

  • Ear pain that may subside quickly
  • Mucuslike, pus-filled or bloody drainage from your ear
  • Hearing loss
  • Ringing in your ear (tinnitus)
  • Spinning sensation (vertigo)
  • Nausea or vomiting that can result from vertigo

When to see a doctor

Call your doctor if you experience signs or symptoms of a ruptured eardrum. Your middle and inner ears are made up of delicate structures that are sensitive to injury or disease. It is important to try to figure out the cause of your ear symptoms and determine whether a ruptured eardrum has occurred.

Causes

Causes of a ruptured (perforated) eardrum may include:

  • Middle ear infection (otitis media). A middle ear infection often results in the accumulation of fluids in your middle ear. Pressure from these fluids can cause the eardrum to rupture.
  • Barotrauma. Barotrauma is stress exerted on your eardrum when the air pressure in your middle ear and the air pressure in the environment are out of balance. If the pressure is severe, your eardrum can rupture. Barotrauma is most often caused by air pressure changes associated with air travel.

    Other events that can cause sudden changes in pressure — and possibly a ruptured eardrum — include scuba diving and a direct blow to the ear, such as the impact of an automobile air bag.

  • Loud sounds or blasts (acoustic trauma). A loud sound or blast, as from an explosion or gunshot — essentially an overpowering sound wave — can rarely cause a tear in your eardrum.
  • Foreign objects in your ear. Small objects, such as a cotton swab or hairpin, can puncture or tear the eardrum.
  • Severe head trauma. Severe injury, such as a skull base fracture, may cause the dislocation of or damage to middle and inner ear structures, including your eardrum.

Complications

Your eardrum (tympanic membrane) has two primary roles:

  • Hearing. When sound waves strike it, your eardrum vibrates — the first step by which structures of your middle and inner ears translate sound waves into nerve impulses.
  • Protection. Your eardrum also acts as a barrier, protecting your middle ear from water, bacteria and other foreign substances.

If your eardrum ruptures, uncommon problems can occur, especially if it fails to self-heal after three to six months. Possible complications include:

  • Hearing loss. Usually, hearing loss is temporary, lasting only until the tear or hole in your eardrum has healed. The size and location of the tear can affect the degree of hearing loss.
  • Middle ear infection (otitis media). A ruptured (perforated) eardrum can allow bacteria to enter the ear. If a perforated eardrum doesn't heal, a small number of people may be vulnerable to ongoing (recurrent or chronic) infections. In this small group, chronic drainage and hearing loss can occur.
  • Middle ear cyst (cholesteatoma). Although very rare, this cyst, which is composed of skin cells and other debris, can develop in your middle ear as a long-term result of eardrum rupture.

    Ear canal debris normally travels to your outer ear with the help of ear-protecting earwax. If your eardrum is ruptured, the skin debris can pass into your middle ear and form a cyst.

    A cyst in your middle ear provides a friendly environment for bacteria and contains proteins that can damage the bones of your middle ear.

Prevention

Follow these tips to avoid a ruptured (perforated) eardrum:

  • Get treatment for middle ear infections. Be aware of the signs and symptoms of middle ear infection, including earache, fever, nasal congestion and reduced hearing. Children with middle ear infections often are fussy and may refuse to eat. Seek prompt evaluation from your primary care doctor to prevent potential damage to the eardrum.
  • Protect your ears during flight. If possible, don't fly if you have a cold or an active allergy that causes nasal or ear congestion. During takeoffs and landings, keep your ears clear with pressure-equalizing earplugs, yawning or chewing gum.

    Or use the Valsalva maneuver — gently pushing air into your nose, as if blowing your nose, while pinching your nostrils and keeping your mouth closed. Don't sleep during ascents and descents.

  • Keep your ears free of foreign objects. Never attempt to dig out excess or hardened earwax with items such as a cotton swab, paper clip or hairpin. These items can easily tear or puncture your eardrum. Teach your children about the damage that can be done by putting foreign objects in their ears.
  • Guard against explosive noise. Avoid activities that expose your ears to explosions. If your hobbies or work involves planned activities that produce explosive noise, protect your ears from unnecessary damage by wearing protective earplugs or earmuffs.
