Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Primary intraosseous arteriovenous malformations are rare. This case report details a successful treatment of a rare arteriovenous malformation in the posterior maxilla using external carotid artery ligation and partial maxillectomy.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Vascular Surgery
  • Radiology

Background:

  • Vascular anomalies typically manifest in soft tissues, with primary intraosseous lesions being infrequent.
  • Intraosseous vascular malformations present diagnostic and therapeutic challenges.

Observation:

  • A 29-year-old male presented with persistent bleeding from an extracted tooth socket.
  • Investigations revealed an arteriovenous malformation (AVM) in the right posterior maxilla, involving the posterior superior alveolar artery.

Findings:

  • Diagnosis was confirmed through hematological, radiological investigations, and angiography.
  • The patient underwent successful treatment via right external carotid artery ligation followed by partial maxillectomy.

Implications:
