Endoscopically assisted removal of ectopic teeth in the floor of the orbit. Case report and latest literature review.

Ectopic sinonasal third molar is a rare condition characterized by the aberrant position of the third molar in the maxillar sinus. The etiology of the teeth in the maxillary sinus is commonly associated to trauma and iatrogenic dental procedures. We present the clinical case of a 33-year-old man who presents an ectopic tooth in the right maxillary sinus, located in the orbital floor, who requires endoscopic control through a maxillary approach when performing the extraction. The endoscopic technique is being increasingly used in the maxillofacial field. Thanks to the endoscopic control for complex extractions like the descibed case, complications such as injuries of the infraorbital nerve or fractures of the different walls of the sinus could be avoided. In conclusion, endoscopic control to perform tooth extractions in the maxillary sinus is a safe option that helps to avoid complications such as fracture of the maxillary sinus walls or fracture of the orbital floor.
