Abstract
An Iatrogenic Foreign Body in the Maxillary Sinus: Report of an Unusual Case
Highlights
Foreign bodies are occasionally found in the paranasal sinuses [1]
Because antral perforation is frequently associated with dental procedures involving apical surgery of the maxillary molar teeth, these procedures often create a pathway for foreign bodies to enter the maxillary sinus [5]
There are reports of a sewing needle which was inadvertently pushed into the maxillary sinus by the patient while attempting to drain a dental abscess [13], and a wooden toothpick [14] which was introduced into the maxillary sinus after an upper second molar extraction which caused an oroantral fistula
Summary
Foreign bodies are occasionally found in the paranasal sinuses [1]. Causes include the escape of material through an oroantral fistula, from facial trauma, and iatrogenic causes [2]. A high-speed Gates-Glidden drill perforated the root and was introduced into the left maxillary sinus during a routine root canal treatment. Practitioners must take great care during dental treatment and endodontic treatment in particular, not to accidentally introduce foreign bodies into maxillary antrum.
