From: Inside-out raising mucosal-tympanomeatal flap approach for the repair of large marginal perforations
A Preoperative image of the perforation; (B–D) flap elevation involving the middle ear mucosa and EAC skin without an additional EAC incision; (E, F) placement of the cartilage-perichondrium graft; (G) the cartilage was positioned medially to the TM remnant, with the perichondrium graft placed beneath the flap; and (H) lateral packing of the graft. Black arrows indicate the mucosal-tympanomeatal flap; red arrows indicate the cartilage; blue arrows indicate the perichondrium; and red triangle indicates the bone forming the medial wall of the middle ear
