Endoscopic Transcanal and Transmastoid Laser-Assisted Resection of Middle Ear Capillary Hemangioma.

ABSTRACT

OBJECTIVE: To present a rare case of a middle ear capillary hemangioma in an adult. PATIENT A 31-year-old woman with a 6-month history of left ear fullness, pressure, tinnitus, and progressive hearing loss. INTERVENTION Endoscopic laser-assisted resection. MAIN OUTCOME MEASURES: Clinical, radiographic, and histopathological findings of a capillary hemangioma. RESULTS: Otoscopy revealed an erythematous and slightly pulsating multilobulated middle ear retrotympanic mass. Her audiogram demonstrated a left-sided mixed hearing loss with air-conduction thresholds in the severe-to-profound range. Computed tomography (CT) imaging was significant for total opacification of the left middle ear and mastoid air cells. She underwent a combined endoscopic transcanal and transmastoid excision of the mass with ossicular chain reconstruction. A KTP laser was used to ablate and shrink down the periphery of the lesion. Pathology of the specimen was consistent with a capillary hemangioma. The patient's pulsatile tinnitus and spontaneous vertigo resolved postoperatively. CONCLUSIONS: Capillary hemangiomas are an uncommon cause of vascular middle ear lesions in adults and typically present with symptoms of aural fullness, pulsatile tinnitus, conductive hearing loss, otalgia, and vertigo. Surgery resection provides definitive treatment and the use of laser ablation techniques can allow for hemostasis and excellent visualization.
