Background:
Eosinophilic otitis media (EOM) is a rare middle ear disease that may closely resemble therapy-resistant otitis media with effusion (OME). The diagnosis is made if eosinophil-rich fluid is present with two or more of the following minor criteria: (a) history of nasal polyps or, (b) bronchial asthma, with (c) viscous fluid in the middle-ear, or (d) conventional otitis media treatment has no effect.
Case Description:
A 70-year-old male with a history of the ASA triad (bronchial asthma, nasal/ethmoidal polyposis and aspirin intolerance) presented with progressive mixed hearing loss. Otoscopy showed bilateral otitis media with effusion (OME). Conventional treatment of this had no effect. Myringotomy resulted in the evacuation of highly viscous middle-ear effusion containing abundant eosinophils. After treatment with oral corticosteroids his symptoms improved considerably. Following later optimisation of his asthma treatment, corticosteroid treatment was stopped and his hearing remained stable.
Conclusion:
The adequate recognition and treatment of EOM will result in the prevention of permanent hearing loss.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
