Anosmia
- Term used to describe having no sense of smell.
- Anosmia/hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts.
Kallmann Syndrome
- A developmental disease affecting both the hormonal reproductive axis and the sense of smell.
- Affected individuals have mutations in either of two different genes KAL1 and FGFR1 (20%) and prokineticin receptor-2 (PROKR2) or prokineticin-2 (PROK2) genes (10%).
Choanal Atresia
- Choanal atresia is the most common form of congenital nasal obstruction, usually diagnosed at birth.[1]
- failure of the posterior nasal cavity (choanae) to communicate with the nasopharynx.
- unilateral or bilateral bony membranous septum located between the nose and the pharynx.
