What Is Conductive Deafness?
Also known as microphone deafness. Hearing impairment due to external and middle ear lesions. It is a type of deafness. The path of external sound waves into the inner ear is impeded by pathological factors of the ear sound system. Ear sound systems include the external auditory canal, tympanic membrane, auditory bone, and snail. Therefore, no matter what causes the damage to the above parts, it can cause deafness. Such as congenital atresia of external auditory canal, palate, foreign body, inflammation and tumor, etc .; diseases of the tympanic membrane, such as rupture and perforation of the tympanic membrane; However, more common are otitis media and obstructive lesions of the external ear canal, so actively preventing and treating otitis media is of great significance in preventing deafness. Treatment is mainly aimed at the etiology, such as feasible shaping of external ear or middle ear deformity, feasible tympanoplasty caused by otitis media, and so on.

Conductive Deafness I. Overview:
- 1. The internal test with a tuning fork was negative, the Weber test was biased toward the diseased side or the heavier lesion, the Schwab test was extended, the bass limit was increased, and the treble limit was normal or slightly reduced. Found in congenital malformations of the external ear, dysplasia of the tympanic cavity, malformation of the ossicular chain, familial otosclerosis, etc .; acquired obstructions of the external ear canal such as condyles, foreign bodies, inflammation, scars, tumors, etc. Middle ear effusion or pus, cholesteatoma, ossicular chain fracture, otosclerosis and tumors.
Conductive deafness 2. Common disorders of conductive deafness
- Otitis media
- The common inflammatory disease of the middle ear, otitis media, is generally divided into two categories, acute and chronic, and the two are divided into non-purulent and suppurative.
- Acute non-suppurative otitis media is more common in adults, and children are often chronically diagnosed without notice. The etiology is mostly eustachian tube obstruction or infection. Tinnitus, tinnitus, audible deafness are common in clinical practice, dizziness, mixed deafness, and tympanic invagination are common in patients with severe effusion. Should strengthen physical exercise, prevent colds, remove the cause in time, medication and go to the hospital for eustachian tube blowing method and treatment of effusion.
- Acute suppurative otitis media is an acute infection caused by the invasion of purulent pathogens in the middle ear mucosa. If the disease occurs in children, the common pathogenic bacteria are streptococcus, staphylococcus and pneumococcus. Acute suppurative otitis media due to untimely, incomplete, or inflammatory lesions of other nearby organs. Suppurative otitis media is usually transmitted by the eustachian tube or tympanic membrane or blood. Clinically visible: systemic symptoms such as fever, earache, hearing loss, tympanic membrane congestion, perforation, etc., sometimes a large amount of pus flows from the tympanic membrane perforation. Principles of treatment include treatment of the cause, control of infection, and maintenance of drainage. Physical exercise should be strengthened to prevent respiratory infections and timely treatment of lesions in adjacent organs to prevent the occurrence of the disease.
