Arrhinia
Arrhinia
Arrhinia (pronounced: ar-rhi-ni-a), also known as Congenital Arhinia, is a rare medical condition characterized by the absence of the nose at birth. The term is derived from the Greek words "a" meaning without, and "rhin" meaning nose.
Etymology
The term Arrhinia is derived from the Greek words "a" (ἀ), which means without, and "rhin" (ῥίς), which means nose. Thus, Arrhinia literally translates to "without a nose".
Symptoms
The primary symptom of Arrhinia is the absence of the external nose, nasal cavities, and olfactory system. This condition may also be associated with other facial abnormalities, such as microphthalmia (abnormally small eyes), hypotelorism (closely set eyes), and cleft palate.
Causes
The exact cause of Arrhinia is unknown. However, it is believed to be due to a disruption in the embryonic development during the first trimester of pregnancy. Some researchers suggest a possible genetic component, but no specific genes have been identified.
Treatment
Treatment for Arrhinia primarily involves surgeries to construct a new nose and nasal passages. This is usually done in several stages during childhood and adolescence. Other treatments may include speech therapy for associated speech issues and psychological support to cope with the condition.
