Our ears are divided into three parts: the outer ear, the middle ear and the inner ear. Some common causes of ear tightness are:
For the external ear, generally speaking, the lesions that can cause the blockage of the external auditory canal can produce the sense of ear tightness, such as cerumen blockage, especially when cerumen completely blocks the external auditory canal; when the external auditory canal boils, the boils are large, the external auditory canal can be blocked; when the external auditory canal is foreign, children like to put rubber, mung beans, plastic beads into the external auditory canal when they play, while adults often fly insects into the external ear in summer Finally, there are some tumors of the external auditory canal, such as papilloma of the external auditory canal.
For the middle ear, the main cause of ear tightness is eustachian tube disease. The tympanum of the middle ear is like a cube box, and the tympanic membrane is on one side of the external auditory canal. Only when the pressure inside the drum is equal to the atmospheric pressure outside, that is, the pressure inside and outside the eardrum is equal, can the sound be best introduced into the inner ear for people to hear. In order to achieve this, the ear and nose are connected by a tube called a eustachian tube. Usually, the tube will open when swallowing or yawning. When air enters the ear from the nose, the pressure in the drum chamber is maintained at a atmospheric pressure. In case of a cold, the mucous membrane of the mouth on the nose side of the eustachian tube is swollen, and the tube cannot be opened, the tympanum will become a closed cavity. After a long time, the air inside will be absorbed by the mucous membrane, and the tympanum will become a negative pressure, and the ear will be stuffy.
The common pathological changes that cause the dysfunction of eustachian tube mainly include: acute rhinitis is common cold, at this time, the nasal mucosa is congested and swollen, resulting in the stenosis of eustachian tube throat; chronic rhinitis, allergic rhinitis, nasal polyps, severe deviation of nasal septum, etc., can also cause the stenosis and blockage of eustachian tube throat; adenoid hypertrophy, adenoid is located in the lymphoid tissue of nasopharynx, adenoid in childhood is often With the increase of age, the adenoids gradually shrink, sometimes the adenoids become too large to block the eustachian tube mouth; congenital cleft palate, the function of levator veli palatini muscle and tensor veli palatini muscle in cleft palate leads to the opening obstacle of eustachian tube mouth; nasopharynx tumor, the benign tumor in nasopharynx is mainly nasopharynx fibroangioma, and the malignant tumor is mainly nasopharyngeal carcinoma.
The rare condition is inner ear disease, which is mainly caused by membranous labyrinthine disease. The most important inner ear disease that causes the sense of ear depression is Meniere’s disease. The main characteristics of this disease are ear tightness, tinnitus, paroxysmal vertigo and fluctuating hearing loss.
