Suspected Silent Sinus Syndrome Identified on Implant Evaluation

A 49-year-old male was referred for implant evaluation at the left maxillary #14 site. During full-volume review, the radiologist identified that the right maxillary sinus was not only hypoplastic but that the anterior and lateral walls were caved in, with the orbital floor bowed inferiorly. The sinus was essentially clear. The radiologist suspected silent sinus syndrome and recommended clinical correlation for signs of hypoglobus or enophthalmos. The ostiomeatal complex was not fully captured in the scan, and further evaluation was recommended.
