To evaluate the selection and strategy in the revision surgery of otoendoscopic tympanoplasty.
Revision endoscopic surgery was performed on the cases with unsatisfactory outcomes after tympanoplasty, which include eardrum adhesion, marginal perforation, eardrum lateral healing, graft (cartilage and perichondrium complex) shift, prosthesis fracture and prolapse.
Postoperative follow-up results showed that the perforation was closed for all patients who underwent revision endoscopic myringoplasty. The marginal perforation was the most common cause for the unsatisfactory outcomes after endoscopic tympanoplasty, and the endoscopic inlay technique with a cartilage butterfly graft is an effective method to deal with this residual marginal perforation. Autogenous adipose tissue for inlay grafting is useful only for some cases. The cartilage and perichondrium complex should be stable fixed.
Endoscopic repair of tympanic membrane perforations is an effective and convenient method for patients with unsatisfactory outcomes after tympanoplasty.
