    The combination of sensorineural and conductive hearing loss leads to mixed hearing loss. It means the damage can be to the middle, outer or inner ear or even to the auditory nerve.

    Treatment 

    Depending upon the type of hearing loss, the doctors may recommend different types of treatments including surgery and medicine. In some cases, listening devices such as aids for hearing can be recommended. The cause and severity of the loss of hearing also decides the type of treatment. For example, hearing loss caused due to aging cannot be cured medically or surgically, but listening devices and other hearing aids are advised to improve the quality of life.

    Medical treatment is advised including surgery and medications particularly in case of conductive hearing loss. Sometimes, even a medical treatment is not necessary and a visit to an audiologist can help diagnose the proper reason behind loss of hearing. Depending upon the analysis, proper treatment can be recommended. Antibiotics are usually prescribed for conductive hearing loss caused due to fluid or infection in the middle ear or earwax blocking the ear canal.

    Using Hearing Aids

    Hearing aids are recommended when the problem cannot be treated medically or surgically. Your caregiver can advise you to consult an audiologist to determine the type of hearing aids that would be appropriate for you. Certain factors such as hearing concerns, listening needs and lifestyle are highly important to determine the appropriate type of hearing aids.
