34 self-inflicted foreign bodies in the maxillary sinus.

Foreign bodies (FB) are a common occurrence in the realm of ENT practice. The most commonly involved sites are nasal cavities, ears, and pharynx. Foreign bodies are accompanied by site-related symptoms and do not pose much of a challenge to well-trained physicians. Foreign bodies may be introduced willingly by the patient or by accident. Paranasal sinus foreign bodies are rarely seen, and most of them are introduced accidentally (25%) or iatrogenically (60%). The latter may occur as a consequence of dental, ophthalmic, and otorhinolaryngological procedures. The maxillary sinus is more frequently involved (75%), followed by the frontal sinus (18%). Only a few cases of self-inoculated paranasal sinus foreign body have been reported in the literature. This paper reports a case of chronic sinusitis secondary to the inoculation of multiple foreign bodies in the maxillary sinus.
