Impacted cerumen, or earwax blockage, is a buildup of earwax that blocks the ear canal and can cause discomfort, hearing loss, and other symptoms. While earwax is a normal, self-cleaning substance, certain factors can cause it to accumulate and harden over time. 

Symptoms:

Symptoms often develop gradually and may include: 

• Hearing loss: A reduction in hearing that may get worse over time.

• Fullness or blockage: A sensation of the ear being plugged.

• Ear pain: An earache (otalgia).

• Tinnitus: A ringing, buzzing, or other noise in the ear.

• Itching or odor: An itchy sensation or an unpleasant smell from the ear.

• Dizziness: A feeling of vertigo or imbalance.

• Cough: A persistent cough, which can be caused by the hardened wax pressing on a nerve in the ear. 

Causes and risk factors:

Several factors can disrupt the ear's natural cleaning process and lead to impaction: 

• Using cotton swabs or other objects: This is one of the most common causes, as it pushes the earwax deeper into the canal and against the eardrum.

• Excessive wax production: Some people naturally produce more earwax than others.

• Narrow or misshapen ear canals: A canal that is narrow or has an unusual shape can trap wax and make natural removal less efficient.

• Hearing aids, earplugs, or earbuds: Frequent use of these devices can interfere with the ear's ability to clear wax on its own.

• Age: As people get older, their earwax tends to become drier and harder, making it more prone to impaction.

• Dermatological conditions: Skin conditions like eczema or psoriasis can cause excess skin cells to build up and mix with the earwax. 

Complications:

If left untreated, impacted cerumen can lead to: 

• Ear infections: The trapped moisture and debris can create an ideal environment for bacteria to grow, causing an infection (otitis externa).

• Increased hearing loss: The blockage can make it difficult to diagnose other hearing issues.

• Damage to the eardrum: Attempting to remove hardened wax improperly can lead to injury.

• Cognitive impairment: In older adults, cerumen impaction has been linked to reversible cognitive issues due to hearing loss. 

Treatment and prevention:

For safe and effective treatment, it is always best to see a healthcare professional. 

• Professional removal: A doctor can use specialized tools, such as a curette or forceps, or use microsuction to clear the blockage under direct vision.

• Irrigation: A doctor can flush out the wax with a syringe filled with warm water and a softening agent. This should only be done by a trained professional, as improper irrigation can cause damage.

• Ear drops: For mild cases, a doctor may recommend over-the-counter or prescribed ear drops to soften the wax. These drops include saline, mineral oil, or hydrogen peroxide.

• Avoid home remedies: Do not use cotton swabs, hairpins, or ear candles to try to remove impacted earwax. This can cause serious injury to the ear canal and eardrum and often makes the problem worse. 

When to see a doctor:

You should see a healthcare professional if you experience symptoms like ear pain, dizziness, or hearing loss. You should seek immediate medical care if you have drainage from the ear, fever, or a foul odor.
