H65.20

Clinical Causes: Eustachian tube dysfunction, which prevents proper drainage of fluid from the middle ear Chronic allergies causing inflammation in the nasal passages and Eustachian tubes Frequent upper respiratory infections Environmental factors such as exposure to cigarette smoke or pollution Anatomical differences, like enlarged adenoids or structural abnormalities Barotrauma from rapid changes in air pressure, such as during flying or diving

Key Symptoms: Hearing loss, often gradual and affecting one or both ears Feeling of fullness or pressure in the ear Mild dizziness or balance issues in some cases Tinnitus, which is ringing or buzzing in the ear Impaired speech or lag in language development in children Discomfort or a sense of blockage in the affected ear

Diagnosis Path: Diagnosis of chronic serous otitis media typically involves a healthcare provider conducting a physical examination of the ear. This may include using an otoscope to visualize the ear canal and eardrum. Additional tests such as tympanometry assess middle ear function, while audiometry evaluates hearing levels. A thorough medical history and examination help determine if fluid buildup persists without infection, establishing the diagnosis of H65.20.

Treatment Protocols: Treatment approaches aim to remove or manage the fluid buildup and restore normal ear function. Common options include: - Observation: Monitoring the condition over time, especially if symptoms are mild, as some cases resolve spontaneously. - Medical management: Use of nasal steroids, decongestants, or antihistamines to reduce inflammation and promote Eustachian tube function. - Myringotomy: A minor surgical procedure to drain fluid from the middle ear by creating a small incision in the eardrum. - Ear tubes: In cases of recurrent or persistent fluid buildup, inserting ventilation tubes can help maintain middle ear aeration. - Addressing underlying causes: Managing allergies or chronic nasal congestion to reduce episodes. Consulting with an ear, nose, and throat specialist (ENT) can help determine the most appropriate treatment plan based on individual circumstances.
