B37.84
Candidal otitis externa
Clinical Classification Guidelines
Medical Intelligence & Overview
Candidal otitis externa, also known as fungal outer ear infection caused by Candida species, is a condition that affects the outer ear canal. This type of infection results from an overgrowth of Candida fungi, which normally reside on the skin and mucous membranes but can cause problems when they multiply excessively. It predominantly affects individuals with a weakened immune system, those frequently exposed to water, or with existing skin conditions. Recognizing the symptoms and understanding the nature of this condition can help in seeking appropriate healthcare and management.
Causes & Symptoms
Clinical Causes: Overgrowth of Candida fungi in the ear canal Prolonged exposure to water, leading to a moist environment favorable for fungal growth Use of ear drops containing antibiotics or corticosteroids that disrupt normal flora Skin conditions such as eczema or dermatitis affecting the ear canal Weakened immune system due to illnesses like diabetes or HIV Trauma to the ear canal from scratching, foreign objects, or frequent cleaning
Key Symptoms: Itching sensation within the ear Discomfort or a feeling of fullness in the ear Redness and swelling of the ear canal Possible discharge that may be white, yellow, or cottage cheese-like Pain when touching or moving the outer ear Partial hearing loss or muffled hearing Scaling or flaking skin within the ear
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a healthcare provider examining the ear using an otoscope, which allows visual inspection of the ear canal for signs of fungal growth and inflammation. Taking a sample of ear discharge for microscopic analysis or culture can confirm the presence of Candida fungi. This helps differentiate candidal otitis externa from bacterial infections or other ear conditions.
Treatment Protocols: Treatment strategies aim to eliminate the fungal growth and alleviate symptoms. These may include:
