Types of Ear Infections in Adults: Middle vs Outer Ear Explained

Imagine finishing a refreshing swim or recovering from a lingering cold, only to notice a dull ache in your ear. At first, you ignore it, but soon the pressure builds, or chewing becomes painful. While many people think of ear infections as a childhood problem, they frequently affect adults, too. The key to relief lies in knowing exactly where the problem starts. At 3 Senses ENT & Dental Clinic, we see how often patients confuse outer ear pain with middle ear pressure. Understanding the specific types of ear infections in adults helps you choose the right care and get back to feeling like yourself.

A Simple Map of Your Ear (Outer vs. Middle)

To treat an ear infection effectively, you first need to know where it is located. Your ear has distinct sections, and infections in each area require different approaches.

• The Outer Ear: This includes the part you see and the ear canal leading down to the eardrum. It is skin-lined and exposed to the outside world.
• The Middle Ear: This is the air-filled space typically located behind the eardrum. It contains three tiny bones that vibrate to help you hear.
• The Connection: The Eustachian tube connects your middle ear to the back of your throat. This tube drains fluid and equalises pressure.
• Why Location Matters: An infection in the canal (outer) usually stems from moisture or skin irritation. An infection behind the eardrum (middle) often follows a cold or respiratory issue.
• Distinct Treatments: Because the causes differ, the treatment adults need varies. One might require drops, while the other might need oral medication or nasal support.

Outer Ear Infection in Adults (Otitis Externa)

This condition, often called “swimmer’s ear,” involves inflammation of the ear canal. It feels very different from a deep middle earache.

• What It Is: An infection of the skin lining the ear canal. It can range from mild itching to severe pain that radiates to the jaw.
• Common Symptoms:
  • Pain when you pull on your outer ear or push on the tragus (the small bump in front of your ear).
  • Itching inside the canal.
  • Redness and swelling that may narrow the canal opening.
  • Clear or pus-like discharge draining from the ear.
  • Temporary muffled hearing if swelling blocks sound.
• What Causes Ear Infections in Adults (Outer Ear):
  • Moisture: Water trapped in the ear after swimming or showering creates a breeding ground for bacteria.
  • Trauma: Cleaning with cotton buds or scratching the canal skin allows bacteria to enter.
  • Irritants: Hair spray, dyes, or even hearing aids can sometimes irritate the skin barrier.
• How to Treat Ear Infection (Outer Ear):
  • Keep it dry: Avoid getting water in your ear while you heal.
  • Ear drops: Doctors typically prescribe antibiotic or antifungal drops to fight the infection directly at the source.
  • Debridement: In our clinic, we may safely clean debris from the canal to help the drops work effectively.

Middle Ear Infection in Adults (Otitis Media)

Middle ear infections occur behind the eardrum and are less common in adults than in children, but they can feel more intense.

• What It Is: An infection where fluid and mucus build up in the middle ear space and become infected by bacteria or viruses.
• Common Symptoms:
  • Deep, throbbing pain inside the ear.
  • A sense of fullness or pressure, like being underwater.
  • Muffled hearing or difficulty understanding speech.
  • Fluid drainage if the eardrum perforates (bursts) from pressure.
  • Fever may accompany the infection.
• What Causes Ear Infections in Adults (Middle Ear):
  • Respiratory Illness: Colds, flu, or sinus infections often trigger swelling in the Eustachian tubes.
  • Eustachian Tube Dysfunction: When these tubes swell or get blocked, fluid gets trapped in the middle ear instead of draining.
  • Allergies: Seasonal allergies can cause chronic inflammation that blocks drainage pathways.
• Ear Infection Treatment Adults (Middle Ear):
  • Wait and See: Mild viral cases sometimes resolve on their own with rest and symptom management.
  • Antibiotics: If the infection is bacterial and severe, your doctor prescribes oral antibiotics.
  • Nasal Support: Decongestants or nasal steroids may help open the Eustachian tube to relieve pressure.

Key Differences: How to Tell Them Apart

Knowing the specific signs helps you describe your symptoms accurately during your consultation.

• The Touch Test:
  • Outer Ear: Pain usually sharpens when you touch, wiggle, or pull on your ear.
  • Middle Ear: Pain feels deep inside. Touching the outer ear typically does not make it hurt more.
• The Lead-Up:
  • Outer Ear: Often follows swimming, heavy sweating, or aggressive ear cleaning.
  • Middle Ear: Often follows a recent cold, sore throat, or allergy flare-up.
• The Sensation:
  • Outer Ear: Often starts with an itch that turns into pain.
  • Middle Ear: Starts with pressure or a “blocked” feeling that turns into a throb.

Safe Home Care and Prevention

While professional care corrects the root cause, you can take steps to manage comfort and reduce future risks.

• Managing Pain: Over-the-counter pain relievers often help manage the ache while medications take effect.
• Warm Compress: A warm (not hot) cloth against the ear can soothe discomfort.
• Keep Ears Dry: During healing, place a cotton ball coated in petroleum jelly in the outer ear while showering to block water.
• Avoid Cotton Buds: Never insert objects into your ear canal. They push wax deeper and can scratch the skin, inviting infection.
• Manage Allergies: If you have chronic congestion, treating your allergies helps keep your Eustachian tubes clear.
• Know When to Act: Understanding how to treat ear infection symptoms early prevents complications like spread to the bone (mastoiditis) or hearing damage.

When to See an ENT Specialist

Some symptoms require more than a general check-up. An ENT specialist has the tools to look deep into the ear and treat complex issues.

• Persistent Symptoms: If pain or fullness lasts more than a few days despite home care.
• Discharge: Any fluid draining from the ear warrants an exam to check for eardrum perforation or outer ear infection.
• Hearing Changes: Sudden or noticeable hearing loss needs immediate evaluation.
• Dizziness: If the infection affects your balance or causes spinning (vertigo).
• Recurring Issues: Adults with frequent ear infections need an exam to rule out underlying structural problems.
• The 3 Senses Approach: At our clinic, we use specialised endoscopes to view the canal and eardrum clearly. This ensures we diagnose the exact type of infection and prescribe the targeted ear infection treatment adults need for a full recovery.

Why Accurate Diagnosis Matters

Treating the wrong part of the ear delays relief.

• Drops vs. Pills: Antibiotic drops treat outer ear infections but cannot reach a middle ear infection behind an intact eardrum.
• Oral Meds: Oral antibiotics travel through the bloodstream to treat middle ear infections, but may not clear a severe fungal outer ear infection.
• Structural Checks: An ENT exam checks for polyps, bone infection, or eardrum issues that a standard exam might miss.
• Chronic Cases: For fluid that won’t drain, procedures like myringotomy (a tiny incision to drain fluid) might be discussed.
• Comprehensive Care: Because what causes ear infections in adults varies so much, our team looks at your whole history—sinuses, allergies, and ear health—to build a lasting solution.

FAQs

1. What causes ear infections in adults?

What causes ear infections in adults varies by type. Outer ear infections (otitis externa) often come from trapped moisture, skin trauma, or irritants like cotton buds. Middle ear infections (otitis media) typically follow colds, allergies, or Eustachian tube blockage that traps fluid.

2. How to treat an ear infection?

How to treat an ear infection depends on the location. Outer ear infections usually need antibiotic or antifungal ear drops plus canal cleaning. Middle ear infections may resolve with watchful waiting, pain relief, or oral antibiotics if bacterial. Keep the ear dry and avoid inserting objects.​

3. Do ear infections in adults go away on their own?

Yes, some ear infections in adults go away on their own, especially viral middle ear infections. Outer ear infections often need drops to clear bacteria. If symptoms persist beyond 3 days, worsen, or include discharge/fever, seek medical evaluation.​

4. How to relieve ear pain while pregnant?

Pregnant women relieve ear pain with acetaminophen (check dosage with your doctor), warm compresses, and keeping the ear dry. Avoid aspirin. Consult an ENT for safe evaluation and treatment, as pregnancy changes may affect antibiotic choices.
