The presence of sinonasal ectopic teeth is a rare entity that is usually asymptomatic. In some cases, the presence of foreign bodies in the maxillary sinus, such as ectopic teeth, can lead to chronic maxillary sinusitis. We report a case of chronic sinusitis because of an ectopic tooth in the roof of the left maxillary sinus in a 50-year-old female who presented with complaints of facial pain in the left maxillary region and purulent nasal discharge. The treatment of ectopic teeth usually consists of the removal of the previous, taking into account its location and possible risks. In this case, the close proximity to the orbit could have led to a greater risk of complications involving the infraorbital bundle. CT scan evaluation is frequently required to identify the exact location and is useful for treatment planning. The traditional surgical approaches to maxillary sinus pathology are transoral Caldwell-Luc approaches or transnasal endoscopic surgery. The method used in this case was the Caldwell-Luc approach. Although more invasive, it allows visualization into the maxillary sinus and superior access for instrumentation of the posterolateral region while permitting manipulation and removal of larger objects. Despite maxillary sinus ectopic teeth being uncommon, it is important for clinicians to become aware and to consider this entity to provide early adequate treatment.
