Because the nasal cavity and the middle ear cavity are connected through the eustachian tube, when the chronic nasopharyngeal long-term inflammatory mucosa spreads and the inflammatory secretions stimulate, the eustachian tube can be inflamed, the eustachian tube mucosa is swollen, and the eustachian tube is swallowed. Occlusion of the mouth; the spread of inflammatory secretions and inflammation to the middle ear can cause otitis media. The inflammatory secretions in the middle ear cavity are exuded, and even purulent secretions can damage the tympanic membrane, causing the sound to be transmitted to the middle ear. At the same time, due to the rupture of the tympanic membrane and the damage of the ossicular chain, the sound waves cannot be amplified by the sound waves. Causes hearing loss. Therefore, some deafness is caused by chronic rhinitis, and there is a close relationship between the two.
Deafness is divided into two categories: conductive deafness and sensorineural deafness. Sensorineural deafness is a cochlear auger. The auditory nerve or the auditory area of the brain has lesions that cannot or only partially experience the incoming sound. Conductive deafness is caused by the outer ear and middle ear lesions, causing the sound energy in the incoming ear to reach the inner ear.
