Deafness, progressive with stapes fixation, also known as Thies Reis syndrome, is a form of conductive or mixed hearing loss caused by fixation of the stapes.[1][2] The stapes is one of the tiny bones in the middle ear. It rests in the entrance to the inner ear, allowing sounds to pass to the inner ear. If it becomes fixated, sound waves cannot pass through to the inner ear, resulting in loss of hearing.[3] This condition may be associated with a number of conditions, including ostosclerosis, Paget's disease and osteogenesis imperfecta, or it may be found in isolation.[2][4][5] It may also result from chronic ear infections (otitis media with tympanosclerosis). The progression of hearing loss is generally slow, rarely profound, and usually resolves following treatment. Conductive hearing loss can be restored through surgery or hearing aids. Sensorineural hearing loss can be managed with hearing aids or cochlear implants.[2]
