    Delayed Endovascular Coil Extrusion following Internal Carotid Artery Embolization
    (Georg Thieme Verlag KG, 2014) Dedmon, Matthew M.; Meier, Josh; Chambers, K; Remenschneider, Aaron; Mehta, Brijesh; Lin, Derrick; Yoo, Albert J.; Curry, William; Gray, Stacey
    Internal carotid artery injury is a rare and devastating complication of endoscopic sinus and skull base surgery that has an associated mortality rate of 15%. This case describes a patient who developed massive epistaxis following routine sinus surgery and was eventually diagnosed with a pseudoaneurysm of the cavernous internal carotid artery. Endovascular coiling and Onyx (Covidien, Irvine, California, United States) liquid embolization were ultimately used to completely occlude the internal carotid artery with resolution of bleeding; however, the patient had an unexpected late complication of coil extrusion through the pseudoaneurysm sac into the sphenoid sinus and nasal cavity. The endoscopic skull base team safely excised the coils endoscopically without recurrent bleeding. We describe the multidisciplinary operative management of this case of endovascular coil extrusion to increase awareness of this potentially life-threatening complication.

    Removal of a Wire Brush Bristle from the Hypopharynx Using Suspension, Microscope, and Fluoroscopy
    (Hindawi Publishing Corporation, 2015) Naunheim, Matthew; Dedmon, Matthew M.; Mori, Matthew C.; Sedaghat, Ahmad; Dowdall, Jayme R.
    Wire brush bristles are an increasingly recognized hazard that can present as a foreign body in the aerodigestive tract. Due to their small size and tendency to become embedded in surrounding tissue, these small metallic bristles present a unique operative challenge to otolaryngologists. Here we present a case of a 40-year-old woman who underwent endoscopic extraction of a wire bristle from the posterior pharyngeal wall using suspension, microscopy, and C-arm fluoroscopy. We believe this is the first published case of an endoscopic removal of a buried foreign body in the hypopharynx using these methods of localization concurrently. By leveraging multiple techniques for visualization, surgeons can avoid open exploration while ensuring complete removal of the object. Additionally, this case highlights the importance of regulatory oversight and consumer awareness of the hazards of grill brushes.
