If a patient presents with the complaint of impaired hearing, your investigations should start with the examination. Visible abnormalities of the structures of the ear can also be responsible for impaired hearing. Only after completing this examination should you proceed with investigating the function of the ear, namely hearing. The hearing examination is an important element in various preventative and social medicine protocols.<\/p>\n

Hearing disorders can be caused by defects in the sound-conducting structures of the ear (the auricle, the external auditory meatus, the tympanic membrane and the middle ear). This is known as conductive hearing loss. They can also be caused by defects in the \u2018sound-processing\u2019 structures (the cochlea, the 8th cranial nerve and the auditory cortex). In such instances we speak of sensorineural hearing loss.<\/p>\n
