The purpose of this paper is to examine panoramic radiographic features of post-Caldwell-Luc maxillary sinus. A characteristic feature of the post-Caldwell-Luc maxillary sinus on panoramic radiographs is a right-angled triangular shape, due to the absence of a floor of the maxillary sinus, radiopacity of the zygomatic bone, thickening of panoramic innominate line, and flattening of the posterior wall. This triangular shape is comparable to the contracted sinus with thickening posterior walls on CT scans. The CT scans also show contents consisting of low or high density tissue in the contracted sinus. Whereas, in MRI contents show a high signal intensity area in a T1-weighted image and a low signal intensity area in a T2-weighted image. This paper also discusses the history of Caldwell-Luc operation technique. Caldwell-Luc was developed concurrently by George Caldwell in the US and Henri Luc in France in the 1980s. The procedure affords a means of access to infected maxillary sinuses and allows for the inspection, diagnosis, and treatment of maxillary sinus diseases. In a Caldwell-Luc operation, first, the maxillary sinus is opened anteriorly through a gingivobuccal incision positioned in the canine fossa. Next, the primary intrasinus disease may then be treated by evacuation of secretions or by excision of pathologic lesions or mucous membrane. Finally, a nasoantral window is formed.
