Overlay or over-underlay myringoplasty is usually used to repair large perforation, which require the tympanomeatal flap elevation and removal of superficial epithelium because of inadequate tympanic membrane (TM) remnant, and place the graft medial to the tympanomeatal flap elevation and lateral to the fibrous layer, it is time-consuming and difficult for the beginner [1], [2], [3]. Although various techniques had been improved, the tympanomeatal flap elevation and graft support were unavoidable [2], [3], [4], [5], [6], [7]. The tympanomeatal flap elevation may damage the chorda tympani and cause the cholesteatoma of external auditory canal (EAC) [8], [9], the graft support of middle ear and EAC result in the temporary ear stuffy and conductive hearing loss and graft injury on removal [10]. Recently, we performed enoscopic perichondrium-cartilage H type technique for repairing large perforations in adult, it doesn't involve raising a flap, the removal of superficial epithelium in the TM remnant, packing of middle ear and EAC. In this study, we reported the graft outcomes and complications of enoscopic perichondrium-cartilage H type technique for repairing large perforations with 3 years of follow-up in adult.
