18 causes of conductive hearing loss, quickly protect yourself after reading

Common types of hearing loss include conductive hearing loss, sensorineural hearing loss, and mixed hearing loss. Knowing your type of hearing loss and correcting the symptoms can effectively improve your hearing symptoms. A common cause of several conductive hearing loss.


The causes of conductive hearing loss include:

1. Ear malformations: including external auditory canal atresia, auricular deformity or disappearance, ossicular deformity or disappearance, cauliflower-like ears, etc. These deformities can cause conductive hearing loss;

2.耵聍 Embolization: is a common cause of conductive hearing loss. Usually it is discharged in the direction of the outer ear canal. Sometimes it accumulates in the ear canal and forms an embolus that partially or completely blocks the ear canal. 耵聍 粽 粽 粽 粽 粽 粽 粽 粽 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 耵聍 If the ear canal is completely blocked, there will be hearing loss. Do not perform audiometry or optional hearing aids before removing them;

3. Eczema of the outer ear: The hearing impaired person feels itchy and painful in the outer ear or outer ear canal, and the skin of the external auditory canal is red and swollen. If the redness is not serious and does not affect the hearing, you can do the audiometry, but you cannot choose the hearing aid immediately;

4. External auditory canal: inflammation of the external auditory canal wall. If the swelling is not serious, it will not cause hearing loss.

5. External ear canal polyps: Polyps are formed by the growth of cartilage in the direction of the ear canal. Any abnormal growth of polyps or bone tissue should be consulted at the ENT.

6. Collapse of the external auditory canal: related to age, the older the age, the more serious the collapse. Collapse of the external auditory canal can cause partial or complete blockage of the ear canal. Lifting the auricle up or behind, can make the ear canal open;

7. Perforation of the tympanic membrane: caused by inflammation, foreign body, fracture, blasting or slap. Small perforations can cause a loss of 10dB-15dB, but small perforations usually heal themselves. Large perforations must be repaired by surgery (tympanic repair);

8. Pussy: Regardless of the color of the pus, consult a GP;

9. Healed after perforation: it looks like a perforation, but the otoscope shines like a mirror, which is caused by healing after perforation. Because the fiber layer can not be regenerated, the tympanic membrane after healing is lacking a layer, and a so-called “mirror film” is formed;

10. Tumor or cholesteatoma: a special type of otitis media. Mostly, the tympanic membrane is perforated, and the middle ear inflammation invades the direction of the ear canal. Persistent flow odor is the main feature. A hearing impaired person with such symptoms should go to the otolaryngology department immediately.


11. Enlarged ear canal: mostly caused after surgery. These people with weak hearing are usually the tympanic membrane and the ossicular chain disappears. At this time, the external auditory canal skin becomes very sensitive. Before choosing a hearing aid, you should consult your doctor first. Usually, when the tympanic membrane is perforated or the middle ear is repeatedly infected, scarring of the tympanic membrane occurs, thereby limiting the activity of the tympanic membrane and causing slight conductive deafness;

12. Tympanic membrane hardening: a white hardened sputum caused by degenerative lesions of the tympanic membrane;

13. Foreign body: Common foreign objects in the external auditory canal: cotton balls, insects, malt and other unpredictable things;

14. Suppurative otitis media: usually caused by a cold or other respiratory infection, bacteria entering the middle ear cavity through the eustachian tube. The eustachian tube is swollen and blocked, so that the liquid in the middle ear cavity cannot be drained. The disease can be acute (severe, but short duration) or chronic (recovery or long duration). Accumulation of pus in the middle ear cavity causes hearing loss. The pressure of the pus can cause pain, and the tympanic membrane loses its normal grayish white color and turns bright red;

15. Non-suppurative otitis media: also known as aeronautical otitis media, secretory otitis media, middle ear effusion, serous otitis media or “gel ear”. It is not purulent, but secretory or serous. It can be undetected for a long time, it doesn’t look serious, but it is not;

16. Cholesteatoma: A “tumor” at the top of the middle ear, sometimes characterized by perforation of the tympanic membrane and eroding the external auditory canal. Sustained odor is a typical symptom and must be consulted immediately by a GP. Usually, after removing the tumor, some degree of permanent hearing loss will be left;

17. Otosclerosis: caused by the sponge of the bone around the ear. Sometimes the sponge becomes a sclerotic foci, which fixes the base of the humerus and weakens or even disappears. This type of hearing loss is generally 60dB-65dB, often accompanied by tinnitus. More women than men, more family history, pregnancy usually triggers this disease. The treatment of otosclerosis usually involves surgery. After the humerus is removed, it is replaced with a silicone tube.

18. Interruption of the ossicular chain: due to loud, slap in the face, traffic accidents, etc.
