Study Notes

The maxillary sinus is the largest paranasal sinus and is bilaterally present.
It is pyramidal in shape with a height of 3.5cm, width of 2.5cm, and length of 3.5cm.
The sinus has four sides related to different surfaces of the maxilla and is related to numerous structures.
The maxillary sinus drains into the nasal cavity through the ostium, which can be reduced in size by surrounding bones.
The sinus is lined by specialized columnar epithelium with cilia that facilitate drainage.
The maxillary sinus can have an anatomic variation called a septa, which divides the sinus into compartments.
The sinus is supplied by several arteries and drained by several veins.
The nerve supply to the maxillary sinus is through several nerves.
The maxillary sinus has clinical significance in dentistry, including extraction complications and implant surgery.
The maxillary sinus functions in humidifying and warming the inspired air, regulation of intranasal pressure, and providing resonance to the voice.
