The sinuses are basically pockets of air in the bone, 2 on the forehead, and one under each eye. The 'inner lining' of the sinuses is a thin layer of tissue. They are all interconnected with the nasal cavity, hense when you get a cold, you have the feeling that there is 'pressure on your head'
The reason for their existence is simple:
They act as natural 'Shock-absorbers'. If the head were to take a direct hit to the forehead, and if the sinuses weren't there, the impact would exert pressure on the rest of the skull. Lack of sinuses would make the skull more prone to cracking.
They have two main functions: 1) As in all sinuses, they give size without added weight and 2) They give depth to the voice. You have the para nasal sinuses, assembled around your nose. You have maxillary sinuses, frontal sinuses, ethmoid sinuses and sphenoid sinuses around your nose. These sinuses make the area around your nose, very light in weight. The diagonally opposite part of the skull is thick and heavy. That is occipital bone for example! This has an evolutionary advantage to human being. After deep inspiration, you can float in the water, without any efforts. So these para nasal sinuses has helped you to keep your nose out of water. The opposite thick part of the skull help you in this endeavour. You can very easily understand the importance of your nose in water verses your nose out of water. That is the reason, why the para nasal sinuses are assembled around your nose. All the other advantages are accessory, probably.
The ear and sinus are connected through the Eustachian tube, which helps regulate pressure in the middle ear. Issues in the sinuses, such as infections or inflammation, can affect the Eustachian tube and lead to ear problems like ear infections or hearing issues. Overall, the health of the ear and sinuses are interconnected and can impact each other's functions.
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).
No, sinuses do not drain into the ears. Sinuses are air-filled cavities in the skull that produce mucus to help moisten and filter the air we breathe. The ears have their own drainage system separate from the sinuses.
No, the ear canals are not directly connected to the sinuses.

Paranasal sinuses are a group of four air-filled spaces. Maxillary sinuses surround the nasal cavity, frontal sinuses are above the eyes, ethmoid sinuses are between the eyes and sphenoid sinuses are behind the eyes.
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.
The ear and sinus are connected through the Eustachian tube, which helps regulate pressure in the middle ear. Issues in the sinuses, such as infections or inflammation, can affect the Eustachian tube and lead to ear problems like ear infections or hearing issues. Overall, the health of the ear and sinuses are interconnected and can impact each other's functions.

The frontal sinuses housed in the frontal bone are the largest sinuses.The maxillary sinuses are the second largest.
Sinuses
If you have a headache just about your eyes, it is very likely that it is your sinuses. Sinus pressure can be very painful.
The superior sagittal sinus, straight sinus, and right and left transverse sinuses meet in a structure known as the confluence of the sinuses
Pansinusitis is the medical term meaning inflammation of all the sinuses.
