Foreign body in the maxillary sinus--possible plastic tube: a case report.

We experienced the case of a patient who had a foreign body in the maxillary sinus. The patient complained of recurrent unilateral badly smelling rhinorrhea. The computed tomography and the magnetic resonance images revealed a foreign body in the maxillary sinus. The foreign body was removed via the Caldwell-Luc approach. The foreign body was a plastic tube, which was supposed to be designed for the drainage of the maxillary sinus. However, the patient did not remember having been subjected to a treatment using such kind of tube. After the surgical removal, the patient became free from the nasal symptoms.
