Classic silent sinus of right maxillary sinus. This condition occurs from blockage of the sinus resulting in negative pressure and lowering of the inferior orbital wall causing facial pain, pressure and in severe cases, enopthalmos (lowering of the eye) leading to vision changes.
Treatment is typically surgical and requires removal of the uncinate process which is typically plastered to the lateral orbital wall. Since the natural opening is low in these patients, itβs crucial to stay inferior to avoid entering into the orbit. Often times, as in this case, 70 degree angled scopes are required for proper visualization, making them technically challenging.
Example below performed in my office under local anesthesia. This patient had no pain and was out of the office in 30 minutes.
