Introduction:
Ectopic eruptions of a tooth in a non-dentate region is a rare entity and such cases have been reported to occur in the nasal cavity, orbital floor, maxillary sinus, mandibular condyle, chin, palate and coronoid process.
Case Presentation:
We report a case of bilateral ectopic eruption of maxillary third molars associated dentigerous cyst. A 27 years old female patient reported to us with chief complaint of purulent discharge form nose and recurrent facial swelling for last 2 years. Complete removal of cystic lining and extraction of ectopic maxillary third molars along with mandibular third molars was carried out.
Results:
Post-operative healing was uneventful.
Discussion:
Bilateral ectopic eruptions of maxillary third molars in Antrum of Highmore (Maxillary sinus) are rarely seen and scantly documented in the literature. Dental ectopia may occur in antrum and present with local sino-nasal symptoms attributed to chronic sinusitis. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature & discussed.
