A Case of Massive Oropharyngeal Bleeding from Pseudoaneurysm of Superior Thyroid Artery Associated with Parapharyngeal Abscess / 대한이비인후과학회지

ABSTRACT

Parapharyngeal abscess is relatively common but it can cause life-threatening complications like internal jugular vein thrombophlebitis, septic shock, airway obstruction, and mediastinitis. The diagnosis is dependent on physical examination, endoscopic view, and CT and MR imaging. The treatment is antibiotics but sometimes incision and drainage are necessary. Pseudoaneurysm in deep neck space is very rare and mainly caused by trauma, postoperative state of head and neck surgery and radiation therapy. We herein report a case of massive oropharyngeal bleeding from pseudoaneurysm of the superior thyroid artery associated with parapharyngeal abscess with a review of related literature.
