What is Conductive Hearing Loss
The outer ear (pinna, ear canal, ear drum) and the tiny bones in the middle ear (malleus, incus and stapes) makes up the conductive system of the ear. When sound is not conducted efficiently through the outer ear to the middle ear, conductive hearing loss occurs. This type of hearing loss can reduce an individual’s ability to hear faint sounds.
Causes of Conductive Hearing Loss
- Absence or malformation of the outer ear and/or the middle ear structures
- Impacted earwax or presence of foreign body in the ear canal
- Hole in the ear drum
- Allergies or ear infections
- Fluid accumulation in the middle ear
- Abnormal bone growth in the middle ear
- Poor Eustachian tube functions
- Benign tumors
- Trauma (skull fracture)
Conductive hearing loss can often be corrected medically or surgically. Treatment options varies based on circumstances. Surgery is usually an option for malformed ear structures. Simple medication may be prescribed for ear infections. Hearing aids may be used if surgery is not a feasible option. If both surgery and traditional hearing aids are not viable, implantable hearing aids, such as bone-anchored hearing aids are en excellent alternative.
