Introduction . Hence, the panoramic radiograph is of value in detection of unsuspected disease. the maxillary sinus during the sinus lift operation.'7X20 There is also a suggestion that maxillary sinus floor elevation contributes to the development of sinus cysts. 1 Eventually, the tumor grows to fill the sinus and the diagnosis is made because the lesion has produced a bulge of the palatal or alveolar ridge area. Pathology Residency and Fellowship Program The Warren Alpert Medical . Acute sinus disease may be associated with air-fluid levels which if present commonly occur in the maxillary sinuses. Maxillary premolar region The radiographs which were taken from premolar region exhibit the floor of the nasal cavity and maxillary sinus, usually separated from septum above the root tip of the second premolar (Fig.3C). Because of the close proximity of maxillary teeth with the maxillary sinuses, these are the most important paranasal sinuses in dental point of view. A systematic approach to diagnosis with a high index of suspicion and an awareness of uncommon lesions is therefore essential. Carcinoma of the maxillary sinus usually remains asymptomatic for a long period of time. Polyps and retention cysts are seen as smooth, outwardly convex soft-tissue masses at imaging (CT, MRI) and cannot be differentiated. This is a blinded retrospective trial . pathology and concluded that over 50% of these cases were of dental etiology. This article reports a case of large KOT of left maxilla involving the entire They are situated deep in the bodies of the maxillae. It is the largest air sinus in the body. These sinuses often get obstructed by abnormal tissue growth or cysts obstructing the nasal passage. Uruguay. Some are more aggressive than others and some have higher recurrence rates. Abnormalities in maxillary sinus emphasizes how important it is for the dentomaxillofacial radiologist to undertake an interpretation of the whole volume of CBCT images. D.
