In the present study, we report two cases of ectopic teeth in maxillary sinus associated to dentigerous cyst (DC) with their clinical features and surgical management. Case reports Case 1: A 30-year-old male was referred with a chief complaint of pain and swelling over right cheek region since 16 months and discomfort of nasal breathing. Case 2: A 28-year-old female reported to the Department of Oral and Maxillofacial Surgery with a chief complaint of facial asymmetry due to swelling on the right side of the face since 6 months. Management: Complete enucleation of the cysts along with the impacted third molar was done under general anesthesia via an intraoral approach by exposing the anterolateral wall of maxillary sinus. The specimens were sent for histopathologic examination which confirmed DC. Conclusion: Complete enucleation of the DC and regular postoperative follow-up with radiographic examination is mandatory to rule out any recurrence.
