Neonate with partial arrhinia.

Arrhinia (/əˈrɪniə/ or /əˈrniə/; also called nasal agenesis) is the congenital partial or complete absence of the nose at birth. It is an extremely rare condition, with few reported cases in the history of modern medicine.[1] It is generally classified as a craniofacial abnormality.


The word arrhinia derives from the Greek root rhinos (nose) prefixed with the Greek negation prefix a-.[citation needed]


The cause of arrhinia is not known.[1][2] Akkuzu's study of the literature found that all cases had presented a normal antenatal history.[2]


Treatment focuses on identifying the nature of the anomalies through various imaging methods, including MRI and CAT scan, and surgical correction to the extent possible.[2]
