Red ear syndrome precipitated by a dietary trigger: a case report

Area of Science:

• Neurology
• Otolaryngology

Background:

• Red ear syndrome is a rare condition characterized by episodic ear erythema and burning pain.
• Triggers include touch, exertion, temperature changes, stress, and hair care, making diagnosis and treatment challenging.

Observation:

• A case report details a 22-year-old woman experiencing hyperacusis, tinnitus, and later, severe red ear episodes.
• Symptom diary identified orange juice and stress as key triggers for her red ear syndrome.
• No underlying head and neck pathology was found; investigations and imaging were negative.

Findings:

• This case is the first to report primary red ear syndrome triggered by a dietary factor, specifically orange juice.
• Avoidance of identified triggers, including orange juice and stress, led to significant symptomatic improvement.
• The findings suggest a direct link between dietary triggers and the pathogenesis of red ear syndrome.

Implications:

• Dietary modifications and stress management can be effective in managing red ear syndrome.
• This report expands understanding of red ear syndrome triggers and potential management strategies.
• Further research into the pathogenesis of red ear syndrome, particularly concerning dietary influences, is warranted.
