A Case of Periodontal Necrosis following Embolization of Maxillary Artery for Epistaxis

الملخص EN

Embolization of the maxillary artery (MA) is a common treatment modality for refractory epistaxis.

Tissue necrosis after embolization of the MA is a rare complication.

Here, we reported the first case of the development of necrosis of soft tissue and alveolar bone in the periodontium after embolization.

A 48-year-old man with poor oral hygiene and a heavy smoking habit was referred to our clinic due to intractable epistaxis.

After treatment with anterior-posterior nasal packing (AP nasal packing), the epistaxis relapsed.

Therefore, he underwent embolization of the MA.

Although he did not experience epistaxis after embolization, periodontal necrosis developed gradually.

The wound healed with necrotomy, administration of antibiotics and prostaglandin, and hyperbaric oxygen therapy.

We speculated that the periodontal necrosis was provoked by reduction of blood supply due to embolization and AP nasal packing based on this preexisting morbid state in the periodontium.

Poor condition of the oral cavity and smoking may increase the risk of periodontal necrosis after embolization.
