The document discusses different types of non-suppurative ear diseases including mucous otitis and serous otitis. Mucous otitis, also called glue ear, is characterized by thick fluid accumulation in the middle ear without inflammation. It commonly affects young children and treatment involves surgical insertion of tubes. Serous otitis involves thin fluid, often due to upper respiratory infections or allergies, and may clear with antihistamines or ear tube insertion. Sensori-neural hearing loss affects the inner ear or auditory nerve and results in impaired hearing without pain or ear discharge.
