Buzzing in the ears may be clinically associated with the following diseases. The first one is neurogenic tinnitus, which is the most common clinically. The general cause may be neurogenic tinnitus induced by insufficient blood supply to the inner ear, poor microcirculation in the inner ear, necrosis of inner ear hair cells, etc. It may be accompanied by clinical manifestations such as hearing loss, a sense of stuffiness and congestion in the ear, and vertigo. It is usually treated clinically with drugs that nourish the nerve, dilate blood vessels, improve inner ear microcirculation, hormones, acupuncture, hyperbaric oxygen and other comprehensive symptomatic treatments. The second type is tinnitus induced by secretory otitis media, tympanitis, acute otitis media, etc. This kind of tinnitus will be gradually relieved after the inflammation is well controlled. The third type of tinnitus is induced by foreign bodies in the ear, such as earwax and flying insects, which stimulate the eardrum. Other cases include vascular tinnitus, tinnitus caused by jugular vein bullae, tinnitus caused by auditory neuroma, and tinnitus caused by abnormal opening of the eustachian tube.
