Case Study
During the retrospective evaluation of a series of one hundred Cone Beam (CB) computer tomographs of patients explored for various reasons conchal recesses (CRs) of the maxillary sinuses were found penetrating the root of the inferior nasal concha. In 6% they were unilateral, and in 16% they were bilateral. The size of the CRs varied from 0.79 mm. (min.) to 7.08 mm. (max.), with an average depth of 2.39 mm. Topographically, there were anterior CRs (retro-lacrimal) located posterior to the nasolacrimal canal, middle and/or posterior CRs located superior to the protrusion of the inferior meatus wall into the sinus cavity, and shallow sagittal CRs extending within the root of the inferior nasal concha. From an anatomical point of view, the CR of the maxillary sinus should be included in the description of the maxillary sinus patterns of pneumatization. Practically, CRs can be accurately diagnosed in CB CT and thus unexpected pitfalls of endoscopic surgery can be avoided.
