Auricular arteriovenous malformation (AVM) occasionally accompanies macrotia. Here, the authors report a case of AVM with macrotia that was treated with transcatheter arterial embolization, percutaneous sclerotherapy, and subsequent otoplasty following partial resection. A 46-year-old man presented with Schobinger stage III AVM. After transcatheter arterial embolization of the feeding arteries using n-butyl-2-cyanoacrylate, 9 sessions of sclerotherapy were performed using 3% polidocanol foam. Partial resection of the AVM nidus and subsequent otoplasty for ear reduction were performed at the age of 50 years. Two years later, the remnant nidus was resected and the protruding ear was surgically corrected. No recurrence was observed, and the enlarged ear was reduced at follow-up 6 months after the final operation.
