When yawning, the ear seems to be ringing with the tympanic membrane, which may be due to cerumen on the surface of the eardrum, or due to the dysfunction of the Eustachian tube.
1. Cerumen on the surface of the eardrum: The skin of the external auditory canal contains ceruminous glands, which normally secrete ceruminous tissue continuously. If a small amount of cerumen is dislodged on the surface of the eardrum, the change in the position of the external auditory canal and tympanic membrane during yawning may lead to tinnitus, resulting in back and forth movement of the cerumen on the surface of the eardrum and a ringing sound.
2. Eustachian tube dysfunction: Eustachian tube dysfunction makes the eustachian tube continuously in the state of occlusion, when yawning to promote the eustachian tube reopens again, the air from the eustachian tube into the middle ear cavity, the airflow impact on the eardrum and the pressure change of the middle ear cavity, thus leading to tympanic membrane ringing.
Therefore, if there is a ringing in the ears when yawning, it is recommended to go to the hospital, complete the relevant examinations to clarify the cause and treat the symptoms.
