A unique case of persistent endochondral cartilage in temporal bone in a child with profound hearing loss is being reported This has never been reported earlier. High-resolution computed tomography of the temporal bone suggested bilateral narrow internal auditory canal and absent semicircular canals with small vestibule but a normal cochlea. The mastoid cavity showed few lucent areas among the air cells. Magnetic resonance imaging showed similar findings along with bilateral thin auditory nerves. During the surgical procedure, the mastoid air cells on the right side were filled with cartilaginous tissue separating it from the posterior fossa. With absolutely no landmarks and a contracted antrum, further procedure was abandoned. Although there are a few contraindications for cochlear implantation, this unique case report highlights one of the rarest conditions which can provide a surgical challenge to the surgeon.
