Which of the paranasal sinuses have openings within the hiatus Semilunaris?
Which of the paranasal sinuses have openings within the hiatus Semilunaris?
Anatomical Parts The hiatus semilunaris (or semilunar hiatus) is a crescent-shaped groove in the lateral wall of the nasal cavity just inferior to the ethmoidal bulla. It is the location of the openings for the frontal sinus, maxillary sinus, and anterior ethmoidal sinus.
Where is hiatus Semilunaris located?
nasal cavity
The hiatus semilunaris is a semicircular shaped opening located on the lateral wall of the nasal cavity. It is a component of the ostiomeatal complex and serves as the opening for the frontal and maxillary sinuses and the anterior ethmoid air cells.
What sinuses drain into middle meatus?
The anterior ethmoid air cells, maxillary and frontal sinuses all drain into the middle meatus.
What drains into hiatus Semilunaris?
The anterior ethmoidal air cells drain into the hiatus. The hiatus is also connected to the frontal sinus by the frontonasal duct. The middle ethmoid air cells drain into the ethmoidal bulla. The maxillary sinus also drains into the semilunar hiatus here, posteriorly.
Where does the sphenoid sinus drain?
The sphenoid sinuses are located centrally and posteriorly within the sphenoid bone. They drain into the sphenoethmoidal recess located within the superior meatus.
How do you unclog a sphenoid sinus?

Where is the semilunar hiatus in the nasal cavity?
Anatomical terminology. The semilunar hiatus or hiatus semilunaris, is a crescent-shaped groove in the lateral wall of the nasal cavity just inferior to the ethmoid bulla. It is the location of the openings for maxillary sinus.
How does concha bullosa affect the maxillary sinus?
Concha bullosa can potentially obstruct the maxillary sinus drainage pathway by narrowing the infundibulum and middle meatus. Coronal image with arrow pointing to paradoxical curvature of the middle turbinate (MT) with convexity of the bone directed laterally.
Where does the maxillary sinus drain into the middle meatus?
The maxillary sinuses usually develop symmetrically. The maxillary sinus ostium drains into the infundibulum which joins the hiatus semilunaris and drains into the middle meatus. The anterior ostiomeatal unit (OMU) is comprised of the frontal sinus ostium, frontal sinus drainage pathway (FSDP), maxillary sinus ostium, infundibulum,
