Hypoglossia
Hypoglossia (pronunciation: /ˌhaɪpəˈɡlɒsiə/) is a rare congenital condition characterized by an underdeveloped or absent tongue. The term is derived from the Greek words "hypo" meaning "under" and "glossia" meaning "tongue".
Etymology
The term "Hypoglossia" is derived from the Greek words "hypo" (ὑπο) meaning "under" or "less than" and "glossia" (γλῶσσα) meaning "tongue".
Symptoms
The primary symptom of Hypoglossia is a noticeably smaller or absent tongue. This can lead to difficulties with speech, swallowing, and breathing. Other symptoms may include a smaller jaw, cleft palate, and other facial abnormalities.
Causes
Hypoglossia is typically a congenital condition, meaning it is present at birth. It is often associated with other syndromes such as Pierre Robin sequence and Hanhart syndrome. The exact cause is unknown, but it is believed to be due to a disruption in the development of the tongue during the early stages of pregnancy.
Treatment
Treatment for Hypoglossia typically involves surgery to reconstruct the tongue and improve function. This may include grafting tissue from another part of the body. Speech and language therapy may also be beneficial.
