title: Ultrasound-guided botulinum toxin injection to treat a parotid fistula following gunshot injury.
abstract: Parotid fistula is a rare but very distressing sequelum of post-operative or traumatic injuries. The management of these injuries has been reported in the literature previously and techniques employed include pressure dressings, surgery and more recently botulinum toxin A (BTA) injections. We present a patient who developed a parotid fistula as a late complication of an extensive gunshot injury to the face with subsequent successful management with ultrasound-guided intraglandular injections of BTA. This case demonstrates that the BTA injection is an effective and safe method under ultrasound guidance and should considered as a first-line treatment option for the treatment of salivary fistulas.
