Iatrogenically induced foreign body of the maxillary sinus and its surgical management: a unique situation.

The maxillary sinus is in close proximity of the maxillary dentition; due to the close interaction between these two, there is a possibility of any disease process affecting one that can spread or concomitantly affect the other. This proximity may lead to foreign bodies to displace into the maxillary sinus and lead to development of infection. The signs and symptoms of affecting one structure can superimpose on the other; this can lead to diagnostic dilemmas.
