  • Central perforation of tympanic membrane is that which is not involving the annulus and is bounded on all sides by the remnant of the tympanic membrane.
  • It can be caused by suppurative otitis media or trauma
  • It is associated with less complications as compared to marginal type of perforation and has greater chance of spontaneous healing
  • Central perforation can be closed once the infection subsides by using grafts (eg: cadeveric dura, temporalis fascia, fat from l0bule)
