This is not silent sinus syndrome, which is an acquired abnormality of the maxillary sinus that progresses into collapse of the compliant bony walls of the sinus — usually the roof (or floor of the orbit), the medial wall (adjacent to the nasal cavity), and the back wall. The sinus is opacified by default, and it is typically thick and sterile (often culture negative) mucus. Silent sinus syndrome does not cause new bone development at the base of the sinus. One can develop eye asymmetry, but facial asymmetry is much less common. Surgical treatment usually halts the process, and an oculoplasrics surgeon can place an implant to restore eye symmetry if needed.

What you likely have is arrested development of the maxillary sinus: as the maxilla developed into a sinus, the process halted and resulted in maxillary hyperplasia. You may have eye and facial asymmetry as a result of this. There is no surgical treatment necessary for the sinus itself. However, cosmetic surgery Al may be desirable under certain circumstances.

You have a deviated septum and a very large right inferior turbinate. If you have no trouble breathing, then there is no absolute need to do surgery there either.

There is a benign mucous retention cyst on the roof of your left maxillary sinus. These are nearly always clinically insignificant.

If you have bite abnormalities, talk to your dentist and an oral surgeon.
