The maxillary sinus is the largest of the sinuses and drains into the middle meatus. Most of the ostia open into the middle meatus and the anterior ethmoid, that together are termed the ostiomeatal complex. [32] Adults have a high concentration of cilia in the ostia. The cilia in the sinuses beat towards the openings into the nasal cavity.
The lateral surface of the middle concha is concave, and assists in forming the middle meatus of the nose.

The frontonasal duct may or may not drain into the ethmoidal infundibulum - this is determined by the place of attachment of the uncinate process of the ethmoid bone: if the uncinate process is attached to the lateral nasal wall, the frontonasal duct will open directly into the middle nasal meatus; if otherwise, it will drain into the infundibulum.
A philtrum piercing, nicknamed a medusa piercing, is an upper lip piercing placed in the philtrum, directly under the septum of the nose. [1] It is typically pierced using a labret stud as jewelry, with the ball sitting outside the mouth in the dip of the top lip.
