Abstract
IntroductionDentigerous 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 presentationThis 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. ConclusionThis 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.

Dentigerous cysts are the second most common form of benign odontogenic cysts
The most frequently involved tooth is the mandibular third molar followed by the maxillary canine, but they may be associated with supernumerary or ectopic tooth [1,4]
Intra-operative, bilateral big cystic masses completely filling both maxillary sinuses were visualized along with a tooth impacted in the floor of the left maxillary sinus and another tooth identified within the right osteomeatal complex obstructing the right maxillary ostium
