The current procedure for Tympanic Membrane Perforation (TMP)  repair requires an open surgery under general anesthesia whereby an incision is made in order to raise the tympanomeatal flap. The purpose of this aggressive stage is only to reach the medial side of the eardrum in order to securely place a graft.

Tympanic Membrane Perforation (TMP) is caused by a variety of different processes such as middle ear infection, direct trauma, and poor post-operative healing following ventilation tubes insertion. TMP limit subjects ability to expose their ear to water, as well as lead to decreased hearing, autophony, pain and chronic ear discharge due to secondary infection.

  • Over 175,000 TMP surgeries are carried out in the US every year.
  • Enabling up to 60% saving in cost reduction
