Objective: Present a case of auricular arteriovenous malformation in a 30-yr-old male patient Method: Design:Case Report Setting:Tertiary Government Training Hospital Patient:One Result: Patient had a pulsatile right auricular mass measuring 9.5x3.2x8.4cm. CT angiography identified a complex vascular lesion supplied by ipsilateral postauricular, internal maxillary and superficial temporal arteries. Preoperative embolization was done and subsequently, a total auriculectomy with preservation of the bony external auditory canal was performed, followed by reconstruction using a cervicopectoral flap and split-thickness skin graft.An improvised silicone tube was utilized to maintain patency of auditory canal. Post operatively,flap remained viable, but the skin graft failed to integrate.Patient reported resolution of ear pain and no change in preoperative hearing.8 months postoperative, no signs of recurrence.Patient was referred for prosthetic right ear. Conclusion: Auricular arteriovenous malformation is a rare and notably challenging condition. While history and physical examination provide diagnosis, imaging determine the lesion's extent and contribute to surgical planning.
