The Teaching Point

Ectopic tooth in the maxillary sinus is a rare condition and may be complicated with various conditions, including chronic or recurrent sinusitis, nasolacrimal duct obstruction, osteomeatal complex disease and nasal polyps. Surgical treatment may be considered for symptomatic patients. CT is useful to differentiate ectopic tooth with other differential diagnoses. 3D-reformatted CT can be used to delineate the morphology, inclination and position of the ectopic tooth. It can aid surgical and endoscopic planning, and predict the prognosis and complications for the patient.

Anomalous Morphology of an Ectopic Tooth in the Maxillary Sinus on Three-Dimensional Computed Tomography Images

Free full text article: Anomalous Morphology of an Ectopic Tooth in the Maxillary Sinus on Three-Dimensional Computed Tomography Images

Abstract
We describe a case of an incidentally-diagnosed ectopic tooth showing anomalous morphology in the maxillary antrum, using three-dimensional reconstruction of computed tomography images of the tooth obtained by multi-detector computed tomography.
