Background: Arrhinia is defined as the partial or complete absence of the nasal structures. It is a defect of embryonal origin and can be seen in association with other craniofacial anomalies, central nervous system anomalies, absence of paranasal sinuses, and other palatal and ocular abnormalities. Very few patients with arrhinia have been reported so far in the history of modern medicine.
Case report: This study reports an adult patient with congenital partial arrhinia and reviews the literature along with the embryological basis of such a rare disease.
Conclusion: Arrhinia is a medical condition with scarce documentation in the literature. This article presents the clinical as well as radiological features of this rare entity.
Keywords: Arrhinia; Hyporhinia; Partial arrhinia.
