Most cases of otitis media will affect hearing, leading to moderate to mild hearing loss, conductive deafness in the short term, and mixed deafness in the long term.


What impact does middle ear fluid have on hearing?

Fluid in the middle ear can cause hearing loss. Because there is mucosa in the middle ear cavity, the mucosa has a secretion function. The secreted liquid is usually discharged through the Eustachian tube. However, if the Eustachian tube is blocked, the liquid will form water accumulation in the middle ear cavity, thus affecting hearing. Two windows, these two windows form a phase difference so that we can hear the sound clearly, and the effusion will flood one of the windows, causing the phase difference to disappear, so deafness will occur.


What is ear effusion?
Due to the structure of the ear, it is easier for bacteria or viruses in the nasopharynx to enter the middle ear cavity through the Eustachian tube, resulting in the formation of middle ear cavity. Inflammation, that is, acute otitis media. The cause of the common cold is a virus. After respiratory infection, the virus enters the middle ear along the Eustachian tube, causing inflammation of the middle ear cavity. The mucous membrane of the middle ear swells or becomes incomplete due to viral infection, allowing bacterial invasion to produce a severe inflammatory and suppurative reaction, usually caused by Streptococcus, Haemophilus influenzae, Moraxella catarrhalis or Staphylococcus aureus infection.

These bacteria enter the middle ear cavity and cause an inflammatory reaction in the middle ear mucosa. First, suppuration occurs and ear fluid accumulates.


What are the symptoms of ear effusion
1. Hearing loss: hearing loss and increased self-hearing. When the head is tilted forward or toward the healthy side, hearing can be temporarily improved due to the movement of fluid. Displacement hearing improvement. When the effusion is thick, hearing may not change due to changes in head position. Children are often unresponsive to sounds, have difficulty concentrating, and have poor academic performance and are brought to the hospital by their parents.
2. Earache: Acute patients may have dull earache, which is often the first symptom of the patient. It can be persistent or throbbing. Chronic earache is not obvious. This disease is particularly related to the feeling of blockage or fullness in the ear, which can be temporarily relieved by pressing the tragus.

3. Tinnitus: mostly low-key and intermittent, such as "crackling" sounds, buzzing sounds, and running water sounds. When the head moves, yawns, or blows the nose, the sound of air passing through the ears may appear.


How to deal with and prevent middle ear effusion
1. Identify the cause of middle ear effusion. Unilateral middle ear effusion in adults requires nasopharyngoscopy To exclude tumors in the nasopharynx, it is necessary to determine whether there is hypertrophy of proliferative bodies for earache.
2. For children, upper respiratory tract infection and adenoid hypertrophy are the main causes.
3. Studies have shown that second-hand smoke is a high-risk factor, so parents must provide children with an environment free of second-hand smoke; it is a heavy responsibility, and disease prevention is always more important than cure.want.

Chronic otitis media will affect hearing and how to deal with it
1. Chronic otitis media often leads to perforation of the tympanic membrane or limited movement of the ossicular chain, and can also lead to conductive or mixed deafness. Conditions permitting. Consider surgery.
2. If you are too old or have a general condition that cannot tolerate surgery, you can consider wearing a hearing aid after controlling inflammation.


Hydroid in the middle ear will have a certain impact on hearing. It is recommended to see a doctor for treatment in time.
