Impaction of third molars is a common condition in oral and maxillofacial surgery. However, ectopic eruption of maxillary third molars into the maxillary sinus is rare. We report the case of a 58-year-old patient who presented with chronic left maxillary sinusitis. Radiological evaluation, including computed tomography, revealed an ectopic left maxillary third molar located in the posterior wall of the left maxillary sinus, in close proximity to the pterygopalatine fossa, associated with a pericoronal cyst. Surgical extraction was performed through an intraoral approach under general anesthesia. The postoperative course was uneventful, with resolution of sinus symptoms. Management of ectopic maxillary third molars requires careful assessment of their anatomical location and relationship to adjacent structures. The choice of surgical approach depends on the position of the tooth and the surgeon’s experience. In asymptomatic cases, conservative management with regular clinical and radiological follow-up may be considered.
