 We report on my own personal case of a 25-year-old resident. I had congenital microtia-atresia unilaterally. Plastic reconstruction of the auricle was performed at the age of 10 and 11, but no medical intervention for atresia was done. During my clinical clerkship for medical student, I was aware of poor speech perception on the affected ear or in noise in the operation room. Subsequently, I asked the otolaryngologists to treat my conductive hearing loss and was offered a cartilage conduction hearing aid. The functional gain was approximately 40 dB, demonstrating that this intervention can provide substantial hearing improvement.
