H65.419

Clinical Causes: Allergic reactions to airborne allergens such as pollen, dust mites, mold, or pet dander Eustachian tube dysfunction, which impairs normal drainage and pressure regulation in the ear Prolonged exposure to environmental irritants that trigger allergy responses Pre-existing allergic conditions like hay fever or asthma Structural abnormalities of the middle ear or Eustachian tubes that promote persistent inflammation

Key Symptoms: A feeling of fullness or pressure in the ear Ears that feel blocked or clogged 耳朵发痒或刺痛感 Hearing loss or muffled hearing Fluid drainage from the ear, which may be clear or discolored Tinnitus, or ringing in the ears Discomfort that persists or worsens over time Recurrent ear infections in some cases

Diagnosis Path: Diagnosis typically involves a comprehensive medical history and physical examination by a healthcare professional. The provider may inspect the ear with an otoscope to look for signs of inflammation, fluid buildup, or other abnormalities. Audiometric tests can assess hearing function. In some cases, additional tests like tympanometry or imaging studies are performed to evaluate middle ear status and rule out other conditions.

Treatment Protocols: Management of chronic allergic otitis media focuses on controlling allergy symptoms and reducing inflammation. Common approaches include: - **Allergy management:** Avoiding known allergens and using medications such as antihistamines or nasal corticosteroids to reduce allergic responses. - **Eustachian tube function improvement:** Techniques like nasal decongestants or nasal irrigation can promote better drainage. - **Medications:** If bacterial infection develops, antibiotics might be prescribed. - **Surgical interventions:** In persistent or severe cases, procedures such as myringotomy (drainage tube insertion) or adenoidectomy may be recommended to improve ear ventilation and reduce allergy triggers. - **Regular monitoring:** Ongoing assessment by healthcare providers helps manage symptoms and prevent complications.
