Background The main risk factors for postoperative failure in tympanoplasties are large perforations that are difficult to repair, annular perforations, and a tympanic membrane （TM） with extensive granular myringitis that require middle ear exploration and mastoidectomy. The aim of this study was to investigate a novel technique of perichondrium/cartilage composite graft for repairing the large TM perforation in the patient of otitis media. Methods Retrospective chart reviews were conducted for 102 patients with large tympanic membrane perforations, who had undergone tympanoplasty from August 2005 to August 2008. Tympanoplasty or tympanomastoidectomy using a perichondrium/cartilage composite graft was analyzed. The tragal or conchal perichondrium/cartilage was used to replace the tympanic membrane in patients. Results Patients aged from 13 to 67 years were followed up in average for 24 months （10-36 months）. Seventy-four ears （72.61%） were used the tragal perichondrium/cartilage as graft material and 27 ears （27.39%） were used the conchal perichondrium/cartilage. Graft take was successful in all patients. Postoperative complications such as wound infection, hematoma, or sensorineural hearing loss were not identified. Nine patients （8.82%） had the partial ossicular replacement prosthesis, 14 patients （13.72%） using the autologous curved incus and 79 patients （77.45%） without prosthesis. Successful closure occurred in 92% of the ears. A total of 85.8% patients achieved a postoperative hearing improvement. Conclusions The graft underlay tympanoplasty using perichondrium/cartilage composite is effective for the majority of patients with large perforation. The hearing was improved even if the mastoidectomy was required in the patients with otitis media with extensive granulation.
