Meatus nasi medius: en el interior de las fosas nasales, espacio situado por debajo del cornete medio y en el que desembocan las celdas etmoidales anteriores, los senos frontales y los maxilares.

   <(F): Méat nasal moyen: les méats sont des passages en forme de gouttière situés entre les cornets des fosses nasales. Il en existe trois (méat inférieur, moyen et supérieur), parmi lesquels le méat inférieur est le plus grand et le méat supérieur le plus petit. Ces méats sont tapissés par une muqueuse.Les terminaisons nerveuses responsables de l'olfaction sont situées dans la muqueuse nasale (ou muqueuse pituitaire).

   <(Ing): Middle nasal meatus: is an canal-like opening that lies behind the nose and reaches back into the skull and into the sinus cavities. Situated between the middle and inferior conchæ, and extends from the anterior to the posterior end of the latter. The lateral wall of this meatus can be satisfactorily studied only after the removal of the middle concha. On it is a curved fissure, the hiatus semilunaris, limited below by the edge of the uncinate process of the ethmoid and above by an elevation named the bulla ethmoidalis; the middle ethmoidal cells are contained within this bulla and open on or near to it. Through the hiatus semilunaris the meatus communicates with a curved passage termed the infundibulum, which communicates in front with the anterior ethmoidal cells and in rather more than fifty percent of skulls is continued upward as the frontonasal duct into the frontal air-sinus; when this continuity.
