<\/figure><\/div>\n\n\n\nAbout one in every 1000 children is born with unilateral hearing loss and roughly three percent of school age children experience some degree of loss. Single sided deafness can impact both a child\u2019s speech recognition and language development as well as their ability to localize sounds.<\/p>\n\n\n\n
What Causes Single Sided Deafness?<\/h2>\n\n\n\n
SSD can be caused by a variety of factors.<\/p>\n\n\n\n
One of the most common causes is acoustic neuroma, a benign, slow growing tumor that can push against the auditory nerve and affect the ability to hear properly in one ear.<\/p>\n\n\n\n
Another condition commonly associated with SSD is sudden deafness, a rapid onset of hearing loss that occurs with little or no warning, often following a viral infection. Patients may develop sudden deafness as a result of an inflammation in the cochlea that causes permanent damage to the hair cells responsible for hearing.<\/p>\n\n\n\n
Additional causes of SSD include:<\/p>\n\n\n\n
- Trauma to the head.<\/li>
- Genetic disorders.<\/li>
- Meniere\u2019s disease.<\/li>
- Labyrinthitis.<\/li>
- Microtia.<\/li>
- Mastoiditis.<\/li>
- Measles.<\/li>
- Mumps.<\/li><\/ul>\n\n\n\n
When Should I See a Doctor?<\/h3>\n\n\n\n
You should seek prompt medical attention if hearing loss in one ear happens suddenly. The quicker you act, the higher chance there is for a full recovery. About 15 percent of the time sudden hearing loss can result in single sided deafness.<\/p>\n\n\n\n
What Symptoms Do Those with SSD Experience?<\/h2>\n\n\n\n
Patients with SSD find understanding speech in the presence of background noise especially problematic and have great difficulty localizing sound (recognizing the location or origin of a sound source). Sound localization depends on subtle hearing cues from two ears; removing one from the equation confuses the brain.<\/p>\n\n\n\n
Many also report experiencing a sensation known as the \u201chead shadow\u201d effect. High frequency sound waves do not move around objects, so they never reach the good ear as the head gets in the way. This prevents those with SSD from hearing s<\/em> or t<\/em> sounds.<\/p>\n\n\n\n
Other symptoms include:<\/p>\n\n\n\n
- Anxiety.<\/li>
- Stress.<\/li>
- Social isolation.<\/li>
- Dizziness.<\/li>
- Difficulty paying attention.<\/li>
- Trouble speaking loudly.<\/li><\/ul>\n\n\n\n
How is SSD Diagnosed?<\/h2>\n\n\n\n
In order to diagnose your type of loss, your audiologist will review your symptoms and medical history before completing a physical exam.<\/p>\n\n\n\n
Your doctor will then complete a comprehensive hearing exam<\/a>. The tests are used to determine your exact type and degree of hearing loss.<\/p>\n\n\n\n
Treatments for SSD<\/h2>\n\n\n\n
While there is no cure for single sided deafness, options exist to help you cope with unilateral hearing. Traditional hearing aids don\u2019t offer much help to those suffering from SSD, but contralateral routing of signal (CROS) hearing aids can improve hearing and localization.<\/p>\n\n\n\n
