Rare incidental foreign body in the maxillary sinus on routine radiographic examination.

Accidental entry of any foreign body into the paranasal sinus could be due to known causes or unknown causes with the patient being either symptomatic or sometimes asymptomatic. Such asymptomatic conditions make it difficult to detect the foreign body for an indefinite period which on a longer duration may lead to various complications later. Routine radiographic examination during dental checkup reports to serve a good purpose in these kinds of cases by accidental detection of such foreign bodies in the maxillofacial region leading to early diagnosis and timely management. The present paper highlights the importance of routine radiographs in detecting a rare type of foreign body (nasal stud) in the maxillary sinus in the asymptomatic patient.
