What causes a foul smell in the crevices of the ear?

Generally, an unpleasant odor in the crevice above the ear may be caused by factors such as sweating, inadequate ear hygiene, earwax buildup, external otitis, or otitis media. Patients are advised to follow medical guidance for appropriate treatment. Specific analyses are as follows:

1. Sweating

Some individuals may sweat easily, and sweat can accumulate in the area above the ear. If not cleaned promptly, this retained sweat may produce an unpleasant smell. It is recommended that patients maintain regular cleaning and personal hygiene.

2. Lack of Ear Hygiene

Failing to clean the crevices above the ears regularly can lead to accumulation of dirt and bacteria, resulting in odor. Patients should use substances such as alcohol to clean and disinfect the affected area.

3. Earwax Buildup

Excessive earwax accumulation in the crevices above the ears may cause a foul smell. Patients can visit the otorhinolaryngology department of a reputable hospital, where doctors can guide the removal using tools such as tweezers, which may help alleviate the symptoms.

4. External Otitis

External otitis is primarily caused by pathogen infection. If there is a fungal infection within the ear canal, symptoms such as itching, increased ear discharge, ear pain, and tinnitus may occur. Due to the fungal infection, an unpleasant odor in the crevice above the ear may develop. As directed by a physician, the ear canal may be irrigated with acetic acid, and oral medications such as itraconazole capsules or terbinafine hydrochloride tablets may be prescribed for treatment.

5. Otitis Media

Otitis media is mainly associated with bacterial infection. If the ear canal is infected with Staphylococcus aureus, symptoms such as purulent ear discharge, pain, and a feeling of fullness in the ear may occur, leading to an unpleasant odor in the crevice above the ear. Treatment may include medications such as cefixime granules or amoxicillin capsules, taken under medical supervision.

In addition, conditions such as external auditory eczema may also cause this symptom. Patients are advised to seek timely medical attention to determine the underlying cause and receive appropriate treatment.
