The nasal meatuses are distinct air passages of the lateral nasal cavity located inferior to each nasal conchae.
Terminology
The plural of meatus is meatus (Latin noun of the fourth declension) or meatuses. Meati is incorrect.
Gross anatomy
There are three main nasal meatuses:
A fourth supreme meatus may exist if the supreme nasal concha is present.
The nasal meatuses receive drainage of the paranasal sinuses and nasolacrimal duct.
