Buzzing in the ears every night is clinically possible with the following diseases.1. Neurogenic tinnitus, which is the most common condition in clinical practice, may be related to poor sleep quality at night, frequent insomnia, anxiety, depression and other adverse factors in patients. This condition may be caused by insufficient blood and oxygen supply to the inner ear due to fluid accumulation in the inner ear membrane vagus, damage to inner ear hair cells, inner ear vascular spasm, inner ear vascular microthrombosis, etc., resulting in neurogenic tinnitus, which manifests as a high-pitched, shrill sound. 2. Some patients have tinnitus induced by secretory otitis media or suppurative otitis media, which is related to factors such as inflammation inside the ear canal. 3. Some patients have vascular pulsatile tinnitus, which may be related to factors such as anatomical malformation of blood vessels or alteration of blood flow, and other common clinical diseases such as jugular vein bullae, arteriovenous fistula, severe hyperthyroidism, and severe anemia. If the ringing in the ears has seriously affected sleep, it is recommended to consult the otolaryngology department of a regular hospital.
