The biological role of the sinuses is debated, but a number of possible functions have been proposed:
- Decreasing the relative weight of the front of the skull, and especially the bones of the face. The shape of the facial bones is important, as a point of origin and insertion for the muscles of facial expression.
- Increasing resonance of the voice.
- Providing a buffer against blows to the face.
- Insulating sensitive structures like dental roots and eyes from rapid temperature fluctuations in the nasal cavity.
- Humidifying and heating of inhaled air because of slow air turnover in this region.

Are Sinuses found in the temporal bone?
The paranasal sinuses (which surround the nose) are found in the following bones: frontal, ethmoid, sphenoid, and maxillary. The maxillary sinuses are the largest of all sinuses. There are also sinuses found near the mastoid process of the temporal bone called the mastoid sinuses. The mastoid sinuses communicates with the inner ear, whereas the paranasal sinuses communicate with the nasal cavity.
How many pairs of sinus are there in human body?
There are four pairs of sinuses in the human body: frontal sinuses (in the forehead), maxillary sinuses (cheekbones), ethmoid sinuses (between the eyes), and sphenoid sinuses (behind the nose).
Which are the biggest sinuses?
The frontal sinuses housed in the frontal bone are the largest sinuses.The maxillary sinuses are the second largest.
What are the names of the sinuses?
The main sinuses in the human skull are the maxillary, frontal, ethmoidal, and sphenoidal sinuses. The maxillary sinuses are located in the cheeks, the frontal sinuses are in the forehead area, the ethmoidal sinuses are between the eyes, and the sphenoidal sinuses are located behind the nose. These air-filled cavities help to lighten the skull, provide resonance to the voice, and contribute to the respiratory system.
