hypoplasia include arrest of development of sinuses due to infection or trauma, congenital first arch syndrome, and other developmental anomalies. Congenital anomalies such as Treacher Collins syndrome are associated with unilateral maxillary sinus hypoplasia. All features of maxillary hypoplasia were absent in the presented 3 cases.DISCUSSION/CONCLUSIONS: This report highlights the incidental finding of a relatively rarely reported and often underdiagnosed sinus pathosis on CBCT, SSS. Furthermore, the literature review underlines features observed on a higher spatial resolution modality with significant reduction in radiation doses. It is important for dental professionals to recognize the existence of SSS in otherwise asymptomatic patients and institute management where needed.
