Sissetungiva

Sissetungiva, also known as the "sitting tongue," is a rare and unusual condition characterized by the tongue being partially or completely fixed in a position of elevation, typically pointing upwards or backwards. This condition is often associated with a neurological disorder, such as a stroke or brain tumor, that affects the muscles controlling the tongue. The exact cause of sissetungiva is not fully understood, but it is believed to be related to damage or dysfunction in the hypoglossal nerve, which controls the movement of the tongue.

Sissetungiva can have significant impacts on a person's ability to speak, eat, and swallow. The condition may also cause discomfort or pain in the tongue and surrounding areas. Treatment options for sissetungiva depend on the underlying cause and may include physical therapy, speech therapy, or surgical intervention. In some cases, the condition may resolve on its own over time.

Sissetungiva is a relatively rare condition, with an estimated prevalence of less than 1 in 100,000 people. It is more commonly diagnosed in adults, although it can occur at any age. The condition is not typically inherited, but there may be a genetic predisposition in some cases. Sissetungiva is not considered a life-threatening condition, but it can have a significant impact on a person's quality of life.
