They are present because if the face was solid bone, the anterior portion of the head would weigh more than the posterior part of the head, making it off balance. The air-filled bones weigh less than solid bone, so the head stays balanced on the neck.
The sinuses help to lighten the skull, provide resonance to the voice, insulate sensitive structures like the eyes and brain, produce mucus to trap foreign particles, and humidify and filter the air we breathe.
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.

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 four main sets of sinuses are the frontal, maxillary, ethmoidal, and sphenoidal sinuses. Their primary functions include reducing the weight of the skull, enhancing voice resonance, and providing insulation for vital structures. Additionally, they help filter, warm, and humidify the air we breathe, and they play a role in mucous production to trap pathogens and debris. Overall, these sinuses contribute to respiratory health and protection.
The paranasal sinuses serve several important functions, including reducing the weight of the skull, which aids in overall head structure and balance. They also play a role in enhancing voice resonance, contributing to vocal quality. Additionally, the sinuses help humidify and filter the air we breathe, trapping pathogens and particulates before they reach the lungs.
If by sinus cavities you mean the confluences of the sinuses, then Yes

dural sinuses, cerebral sinuses, or cranial sinuses
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.
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).
The frontal sinuses housed in the frontal bone are the largest sinuses.The maxillary sinuses are the second largest.
