Ectopic tooth in maxillary sinus: Case series
A 48 year old female reported to us with a chief complaint of heaviness over left cheek with decrease in sensation in the area of cheek and upper lip of same side since four months. Clinically maxillary third molar of that quadrant was missing and there was hypoesthesia of infraorbital nerve. There was no swelling or pain. Computed tomography (CT) scan showed a well defined irregular opacity surrounded by a soft tissue mass in the right maxillary sinus []. CT Scan showed a fully developed ectopic maxillary third molar in the sinus about 14mm above the root apices of first molar. The surrounding soft tissue lesion was extending up to floor of the orbit. But there was no ophthalmic involvement. Through a maxillary vestibular incision a bony window of 15 × 20 mm was made on the antero-lateral wall of the sinus. The tooth along with surrounding soft tissue that was attached to the CEJ was removed through a Caldwell-Luc procedure []. The histopathological examination of the specimen turned out to be dentigerous cyst. The hypoaesthesia of infraorbital nerve was resolved in six months time postoperatively. The patient was followed-up for one year and she was asymptomatic.
