Bilateral dentigerous cysts and ectopic teeth in the maxillary sinuses: A case report and literature review.

INTRODUCTION: Dentigerous cysts are the second most common form of benign odontogenic cysts. These cysts are commonly single lesions. Bilateral and multiple dentigerous cysts are very rare.

CASE PRESENTATION: This article presents a rare case report of bilateral dentigerous cysts associated with two ectopic teeth located atypically in the maxillary sinuses in a 19-year-old male manifesting as bilateral upper jaw pain, post-nasal discharge and recurrent sinusitis which was managed via the endonasal endoscopic approach by enucleation of the cysts and teeth removal.

CONCLUSION: This paper presented our experience in the management of a rare case of bilateral dentigerous cysts associated with ectopic teeth in the maxillary sinuses. Ct scan of the paranasal sinuses confirmed the diagnosis and the endonasal endoscopic approach is superior to the external approaches in preserving physiological function in managing these patients.
