<br/><br/> Aim of the work: To evaluate  the endoscopic trans-canal trans  perforation underlay cartilage  tympanoplasty  using  the partial thickness mosaic technique by assessing the graft take rate and hearing results and  time consuming to compare it to endoscopic  trans-canal  underlay  cartilage  tympanoplasty  through elevation of the posterior meatal wall  Patients  and  methods:  Thirty  patients  were  randomly divided into 2 equal groups. Group 1 had endoscopic trans-canal trans perforation underlay cartilage  tympanoplasty using the partial thickness mosaic technique while, Group 2 had trans-canal underlay cartilage tympanoplasty using the partial thickness mosaic technique through elevation of the posterior meatal wall
