History
Although patients rarely present with a complaint of decreased hearing, most have no specific hearing concern. Instead they present with depression, confusion, social isolation, or poor job performance, which may be caused or complicated by hearing impairment. Family members note abnormal, slow, or overly loud answers, a sudden tendency to monopolize or disrupt conversation, or to tilt the head in conversation. CHL is often of sudden onset but of a mild degree. Complete occlusion or rapid collection of fluid in middle ear causes an abrupt change in hearing. SNHL can be abrupt and severe (stroke, idiopathic, trauma), or gradual (MeniereTechnorati Tags: CHL, SNHL, Hearing Loss, OSCE's syndrome, acoustic neuroma, hypothyroidism). CHL often affects the quality of hearing first. Described as muffled like a head in a drum,the patient may lose high frequency and voice discrimination; however,
they are still capable of detecting subtle sounds. SNHL, when not associated with tinnitus, can have good quality but diminished hearing usually more profound than CHL.
