A Case of Therapeutic Percutaneous Embolization of Spontaneous Arteriovenous Fistulas with Pulsatile Tinnitus Involving the Branches of the Left External Carotid Artery / 대한이비인후과학회지

Arteriovenous fistulas of head and neck, especially the external carotid artery are uncommon lesions usually of traumatic origin. They also may be spontaneous, inflammatory, or congenital origin. They maybe accompanied by symptoms and signs such as pulsatile tinnitus, pulsatile mass, palpable thrill, and machine like bruit. Recently, we experienced a case of spontaneous arteriovenous fistula of external carotid artery, treated by coil embolization. The patient noticed pulsatile tinnitus in the left posterior auricular area and left upper neck area. She had no history of head trauma. External carotid angiogram showed fistula between the branches of the external carotid artery (occipital artery, middle meningeal artery, posterior auricular artery) and the internal jugular vein. The fistulas were successfully controlled by coil embolization.

A Case of Pleomorphic Adenoma of the External Auditory Canal / 대한이비인후과학회지

Pleomorphic adenomas mostly occur in major salivary glands. Pleomorphic adenomas arising in the external auditory canal are very rare. The clinical features and natural history of patients with this tumor are obscure. The patients with pleomorphic adenoma of the external auditory canal mostly complain of painless lump, otorrhea, ear fullness and hearing loss. Treatment of choice is a wide excision of tumor to prevent local recurrence. We experienced a case of pleomorphic adenoma in the external auditory canal causing ear fullness and mild otalgia which was treated by local excision via endaural approach. The patient has been free of disease for about 14 months after the treatment. We report the case with a review of literatures.
