Abstract :
Introduction:
Supernumerary teeth are frequently reported in dental clinical practice; however, eruption in nasal
cavities and paranasal sinuses is an extremely rare clinical entity.
Case Report:
We report two cases with a history of recurrent nasal discharge and obstruction. In both cases, clinical
and radiological findings confirmed the presence of an inverted supernumerary tooth erupted in the
sinonasal cavities (i.e., the right nasal fossa and left maxillary sinus, respectively). We managed the
cases with transnasal endoscopic approach. A survey of the English literature identified 69 documented
cases with intranasal supernumerary teeth within January 1st, 1886 to December 31st, 2017.
Conclusion:
Inverted supernumerary teeth should be considered among the potential causes of unilateral nasal
obstruction and rhinosinusitis and included in differential diagnoses among the fibro-osseous lesions of
the sinonasal cavities.
