The ear is connected to the nasopharynx, and the middle ear cavity is a confined space with the only connection to the outside world through the Eustachian tube to maintain air pressure balance in the middle ear cavity. One end of the Eustachian tube opens into the tympanic cavity and the other end opens into the nasopharynx. The Eustachian tube mainly serves to maintain the pressure inside and outside the tympanic cavity, and at the same time has the function of draining the fluid inside the tympanic cavity.
One of the more common clinical symptoms is a blocked ear, which is known as a stuffy, blocked ear, and in some severe cases may be accompanied by hearing loss. The most common causes are cerumen impaction of the external auditory canal; rhinitis, sinusitis, adenoid hypertrophy, nasopharyngeal occupation and other causes of dysfunction of the Eustachian tube; and neurodeafness, which can also cause stuffy, blocked ears.
Therefore, if the patient has symptoms of ear blockage, it is necessary to go to the hospital in time to improve the corresponding examination to clarify the cause of targeted treatment.
