In medicine, an ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicles and facilitates the conduction of sound waves from the tympanic membrane to the inner ear.[1] There are two common types of ossicular replacement prostheses, the total ossicular replacement prosthesis (TORP) and partial ossicular replacement prosthesis (PORP). A TORP replaces the entire ossicular chain while a PORP replaces only the incus and malleus but not the stapes. Indications for use of an ossicular replacement prosthesis include:[1]

  • Chronic middle ear disease
  • Otosclerosis
  • Congenital fixation of the stapes
  • Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery
  • Surgically correctable injury to the middle ear from trauma
