A 16-year-old female who had left auricular sinus infections was admitted to our hospital. On physical examination, bilateral sinus tract openings were noted at the cavum conchae. We used a surgical microscope to complete the total resection of the bilateral sinus at the cavum conchae. Also dissected was the cartilage from the cavum conchae. To our knowledge, surgical excision of cavum conchae sinuses has not been previously described.
