the mucosae of these two regions are continuous, so ear infections may follow a core throat or other types of pharyngeal infections.
It is important that the auditory tubes and the sinuses drain into the nasal cavities and nasopharynx because otherwise they would become blocked with mucus and prevent respiration.
Sinuses
The cranial cavity is the primary cavity of the skull; it contains the brain. In addition, the skull has four other pairs of cavities called sinuses. They are the frontal sinuses, maxillary sinuses, sphenoid sinuses, and ethmoid sinuses.

The ventricles are cavities within the brain that connect with each other, with the subarachnoid space of the meninges and with the central canal of the spinal cord.
The mucous membrane-lined cavities found in several bones surrounding the nasal cavities are called paranasal sinuses. These sinuses include the frontal, maxillary, ethmoid, and sphenoid sinuses. They help to lighten the skull, produce mucus, and regulate the resonance of the voice.

Frontal Sinuses.....
Yes, the sinuses can resonate sound to some extent due to their hollow cavities. However, this resonance is minimal compared to the resonance effect of the nasal and oral cavities.
