Clinical Presentations of Fungal Acute Otitis Externa (AOE)
Fungal AOE is an infection of the outer ear canal, typically caused by fungal organisms such as Aspergillus or Candida. The clinical presentations of fungal AOE include:
- Itching, redness, swelling, and discharge from the ear canal
- Inflammation and infiltration of the ear canal, leading to symptoms such as pain, tenderness, and difficulty hearing
- Irritation of the nerves in the ear canal, leading to symptoms such as itching, burning, or tingling sensations
- Increased blood flow to the affected area, leading to redness, swelling, and warmth
Special Considerations
The following systems may be affected in fungal AOE:
- Infectious/Inflammatory/Infiltrative: Fungal AOE is an infection of the outer ear canal, typically caused by fungal organisms such as Aspergillus or Candida
- Neurology: The infection can cause irritation of the nerves in the ear canal, leading to symptoms such as itching, burning, or tingling sensations
- Vascular/Hematology: The infection can cause increased blood flow to the affected area, leading to redness, swelling, and warmth
- Gastrointestinal: Some medications used to treat fungal infections, such as antifungals, can have gastrointestinal side effects such as nausea, vomiting, or diarrhea
- Drug-effect: Treatment of fungal AOE often involves the use of antifungal medications, which can have side effects such as allergic reactions, skin rash, or interactions with other medications
Potential Pit-Falls
Some potential pit-falls in the management of fungal AOE include:
- Misdiagnosis or delayed diagnosis, leading to prolonged symptoms and increased risk of complications
- Inadequate treatment, leading to treatment failure or recurrence of the infection
- Allergic reactions or interactions with other medications, leading to adverse effects or reduced efficacy of treatment
Note: The provided evidence 1 does not directly address the clinical presentations of fungal AOE. The information provided is based on the suggestions and general knowledge of the topic.

- Misdiagnosis or delayed diagnosis, leading to prolonged symptoms and increased risk of complications
- Inadequate treatment, leading to treatment failure or recurrence of the infection
- Allergic reactions or interactions with other medications, leading to adverse effects or reduced efficacy of treatment
- Failure to consider the potential for fungal infections, such as those caused by Aspergillus or Candida, as mentioned in 2
Nuances and Special Populations
Certain populations may be more susceptible to fungal AOE, such as those with compromised immune systems or those who have recently used antibiotics or immunosuppressive medications. Additionally, fungal AOE can present similarly to bacterial AOE, making diagnosis and treatment challenging. As mentioned in 2, the most common fungi involved in external otitis are Aspergillus and Candida species.
