Rhinology
Rhinology ( Greek: ῥίς, gen.: ῥινός - rhis, rhinos "nose") is the study of the nose, including the sinuses. Rhinology concerns itself with medical and surgical diseases of the nasal passages as well as paranasal sinuses. It is becoming more important after the introduction of nasal endoscopes.
A rhinologist is a specialized otolaryngologist who specifically treats the nose.
