HEARING LOSS |
|
A hearing impairment is a decrease in one's ability to hear (i.e. perceive auditory information). While some cases of hearing loss are reversible with medical treatment, many lead to a permanent disability (often called deafness).
If the hearing loss occurs at a young age, interference with the acquisition of spoken language and social development may occur. Hearing aids and cochlear implants may alleviate some of the problems caused by hearing impairment, but are often insufficient. People who have hearing impairments, especially those who develop a hearing problem later in life, often require support and technical adaptations as part of the rehabilitation process.

LINGUAL NERVE INJURY |
|
Lingual nerve injury or damage can result in anesthesia (numb tongue), paresthesia (tingling), or dysesthesia ( pain and burning ) in the tongue and inner mucosa of the mouth. This can be due to complication of tooth extraction of the wisdom teeth ( third molar ) or dental anesthetic injection (nerve block) for fillings, crowns. It result in a chronic pain syndrome or neuropathy. If the inferior alveolar nerve is involved, numbness of the lip may result. Some people have injury to the inferior alveolar nerve. While this category addresses lingual nerve damage, inferior alveolar nerve damage is even more common. The injury can result in anesthesia, paresthesia, or dysesthesia of the chin, lower lip, and the jaw. This nerve can be injured by injection, but is more commonly injured during wisdom tooth extraction. It can also be injured by root canal procedures, other tooth extractions and with placement of implants.
