Vertigo and Hearing conditions
Benign paroxysmal positional vertigoBenign paroxysmal positional vertigo is a disorder caused by displaced otoliths in the inner ear, leading to brief episodes of vertigo triggered by head movements.Central VertigoCentral vertigo is dizziness caused by lesions in the brainstem or cerebellum, often presenting with neurological deficits and abnormal vestibular testing.CholesteatomaCholesteatoma is an abnormal skin growth in the middle ear causing chronic infection, hearing loss, and potential bone erosion if untreated.Ménière diseaseMénière disease is a disorder of the inner ear causing episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the affected ear.Noise-Induced Hearing LossNoise-induced hearing loss results from prolonged exposure to loud sounds causing damage to cochlear hair cells, leading to sensorineural hearing impairment.Otitis ExternaOtitis externa is an infection of the external ear canal often caused by Pseudomonas aeruginosa, presenting with ear pain, discharge, and canal swelling.Otitis MediaOtitis Media is an infection or inflammation of the middle ear often caused by bacteria or viruses, leading to ear pain, fever, and hearing difficulties.Peripheral VertigoPeripheral vertigo is caused by inner ear dysfunction, presenting with sudden onset spinning sensation and nystagmus, often triggered by head movements.PresbycusisPresbycusis is age-related sensorineural hearing loss caused by degeneration of cochlear hair cells and auditory nerve fibers, leading to gradual bilateral hearing decline.
