Endonasal transsphenoidal endoscopy-assisted removal of a shotgun pellet in the sphenoid sinus: a case report.
BACKGROUND
Gunshot accidents are not uncommon in Taiwan, but involvement limited to the ocular region and sphenoid sinus is rare. Minimal invasive treatment by endonasal transsphenoidal endoscopy-assisted procedure should be considered if there are no additional injuries in the craniocerebral region.


METHODS
A 39-year-old man had severe pain in the left eye with resulting blindness after being accidentally hit in the left eye by a gunshot pellet while walking in a wooded area. He was referred from another hospital with the impression of left eyeball rupture. There was no severe neurologic deficit except for blindness of the left eye when he arrived at the emergency department of our hospital. Brain and orbits CT scans showed a round metallic foreign body at the right sphenoid sinus without predominant damages of brain parenchyma. Endonasal transsphenoidal endoscopy-assisted procedure was used to remove the shotgun pellet, and the patient had good clinical outcomes.


CONCLUSIONS
Herein we present this rare case to show the possibility of a shotgun pellet injury remaining in the sphenoid sinus. The role of radiological studies such as CT scans and intraoperative C-arm fluoroscope plain films in diagnosis and management of this case is affirmed. The strategy of minimally invasive treatment by endonasal transsphenoidal endoscopy-assisted procedure for those limited injuries is a good choice for treatment.
