Ectopic tooth in maxillary sinus: Case series
A 21 year old female reported to us with a complaint of pain and swelling over right cheek region since one month. She had a history of two courses of antibiotics prescribed by her physician. When the swelling increased and became noticeable in right buccal sulcus area, she was referred to us. Clinically, maxillary deciduous second molar was over retained and permanent second premolar was missing in that quadrant. Radiograph showed an ectopic tooth along with large cystic lesion occupying the entire maxillary sinus and resorption of the root of retained deciduous second molar []. A gingival sulcular/crevicular incision was made from lateral incisor to first molar including extraction socket of the retained tooth with anterior releasing incision and buccal mucoperiosteal flap was elevated. A part of antero-lateral wall of the sinus was found to be resorbed. The existing window was extended to access the tooth and the lesion. The ectopic tooth along with surrounding soft tissue was removed. The cystic lesion was attached to the tooth cemento-enamel junction (CEJ) []. The specimen was then sent for histopathological examination which turned out to be a dentigerous cyst. The patient is on a regular follow up for more than a year with no evidence of recurrence.
