Endoscopic transcanal tympanoplasty type I in children: Evolving experience in tragus perichondrium vs. acellular porcine small intestinal sub-mucosa grafts.

Objectives: Endoscopic trans-canal tympanoplasty type I (ETT) is gradually diffusing worldwide. It mainly allows less invasive surgery in children with respect to a microscope approach by avoiding post-auricular access. The aim of this study is to illustrate our experience in endoscopic reconstruction of tympanic membrane, using autologous tragus perichondrium (TP) and non-autologous acellular porcine small intestinal sub-mucosa (SIS) as grafts.
