<\/div>\n\n\n\nWhy Is Sudden Hearing Loss Not a Wait-and-See Situation?<\/h2>\n\n\n\n
Sudden hearing loss deserves prompt attention because some types are more time sensitive than others.<\/strong> A rapid change in one ear<\/a> may turn out to have a relatively simple explanation, such as earwax or fluid. But if the change is sudden sensorineural hearing loss (SSHL), early diagnosis and treatment may improve the chance of recovery.<\/p>\n\n\n\nWhat Is Sudden Sensorineural Hearing Loss?<\/h3>\n\n\n\n
SSHL, sometimes called sudden deafness, is a rapid loss of hearing involving the inner ear or auditory nerve. It typically develops within 72 hours and most often affects one ear. The National Institute on Deafness and Other Communication Disorders (NIDCD) notes that people may first notice SSHL when they wake up or try to use the affected ear.<\/p>\n\n\n\n
Why Can SSHL Feel Like a Blocked Ear?<\/h3>\n\n\n\n
SSHL does not always feel like a dramatic loss of hearing. It may simply seem as though one ear is plugged or muffled, sometimes accompanied by tinnitus, dizziness, or ear fullness. Because those symptoms can also occur with congestion or other common ear problems, a diagnostic hearing test is important for determining what is actually happening.<\/p>\n\n\n\n

<\/div>\n\n\n\nWhy Does Sudden Hearing Loss Happen?<\/h2>\n\n\n\n
In many cases, there is no clear explanation for why sudden sensorineural hearing loss occurs. This is known as idiopathic sudden hearing loss. When a cause can be identified, it may be related to an infection, autoimmune condition, circulation problem, inner ear injury, or another medical condition.<\/p>\n\n\n\n
What If There Is No Clear Cause?<\/h3>\n\n\n\n
Not finding a cause is common. The National Institute on Deafness and Other Communication Disorders (NIDCD) reports that only about 10%<\/a> of people diagnosed with sudden deafness have an identifiable cause.<\/p>\n\n\n\nDepending on your symptoms and medical history, your healthcare provider may recommend additional testing to rule out less common causes. For example, an MRI may be used to look for conditions affecting the auditory nerve, such as an acoustic neuroma. These evaluations are about getting a clearer picture of your hearing health, not assuming something serious is wrong.<\/p>\n\n\n\n

<\/figure>\n<\/div>\n\n\nDiagnosis starts with determining whether the hearing change is sensorineural or caused by something in the outer or middle ear. A diagnostic hearing test, or audiogram, can help make that distinction. If SSHL is suspected, prompt medical evaluation is recommended so you can discuss treatment while it is most likely to be beneficial.<\/p>\n\n\n\n
