Furuncle in the Ear: What It Is, Where It Occurs, and How It Manifests

A painful boil in the ear often turns out to be a furuncle — an inflammation of a hair follicle. Below: what this formation is, where in the ear it appears, and by which signs it is recognized.

What a furuncle in the ear is and how it differs from other formations

A furuncle, or boil, is an acute purulent-necrotic inflammation of a hair follicle, sebaceous gland, and surrounding connective tissue. It is caused by pyogenic bacteria, mainly Staphylococcus aureus. Externally it is a dense, painful nodule that gradually fills with pus.

Similar conditions exist nearby. Folliculitis is inflammation of one or several hair follicles. A carbuncle is a group of furuncles that have merged into one large focus. Furunculosis is the appearance of furuncles at different stages, one after another. The difference lies in depth and scale: in a furuncle, the tissues around the follicle are involved in the process.

Where a furuncle in the ear appears

A follicle can become inflamed wherever hair grows. Most often furuncles occur on the skin of the face, neck, back of the head, back, armpits, buttocks, and thighs. In the ear, a furuncle can occur in the external auditory canal — furuncles in the auditory canal and in the nose can be very painful.

Why a boil in the ear develops

The mechanism is the same: damage to a hair follicle allows infection to penetrate deeper — into the follicle itself and the tissues beneath it. Then factors that facilitate inflammation come into play: contaminated skin, careless shaving, increased sweating and sebum production, poor diet, metabolic disorders, reduced immune activity, hypothermia, and minor skin injuries.

The risk is higher with diabetes and HIV, with steroid use, with eczema, with pronounced excess weight or malnutrition. It has been noted that furuncles are more common in men and in people who are in close contact with a person who has furuncles.

How a boil in the ear manifests: stages of development

First, an itchy or painful spot appears. It is pink-red, swollen, and dense to the touch. As pus and dead tissue accumulate, the pain intensifies, and the nodule itself comes to resemble a fluid-filled little ball or cyst. When the pus drains, the pain subsides.

Typical signs: a white or yellow center, rapid growth, redness of the surrounding skin, oozing, and crusts. The size ranges from a pea, but can reach that of a golf ball. There may be fatigue, fever, general malaise, and itching before the nodule appears.

On the skin, a painful follicular pustule is visible against a background of red erythema with necrosis in the center — the core of the furuncle. After the necrotic tissue is rejected, the focus heals by scarring. Most often a furuncle opens and drains within two weeks, sometimes on its own. Doctors advise against squeezing it: this is how the infection spreads.

Why a furuncle of the auditory canal is dangerous

Localization in the ear does not make the inflammation harmless. Regional lymph nodes react to processes near the ear — lymphangitis and lymphadenitis develop. Cellulitis of the tissues of the head and neck is possible. Among the general complications are abscesses of the skin, brain and spinal cord, kidneys, and other organs, infection of the brain, heart, and bones, sepsis, spread of infection to other areas of the skin, and persistent scars. Furuncles on the face are especially dangerous: purulent meningitis and sepsis have been described.

When to see a doctor

The diagnosis is usually made by appearance. If the picture is unclear, the doctor may take a fluid sample for culture and look for staphylococcus or other pathogens.

• the furuncle persists for two weeks and does not resolve;
• furuncles appear again and again;
• a group of furuncles has formed nearby — a carbuncle;
• the furuncle is on the face, or the skin around it is hot, painful, and swollen;
• there is fever, chills, weakness, or a weakened immune system.

A furuncle in the ear by itself is not a reason to call an ambulance. 103 or 112 are needed if the condition rapidly worsens and signs of infection spread appear — for example, red streaks radiate from the boil.
