The canal wall down mastoidectomy can secure a good operation field and remove the pathology easily, but it accompanies a cavity problem. To reduce the cavity problem, mastoid obliteration is conducted using multiple materials. And proper hemostasis is an important prerequisite for a successful outcome in all operative fields. TachoSil^® is used in many surgical specialties, especially for diffuse bleeding. TachoSil^® is not only used for hemostasis but also for closure of other anatomical structures. Recently, we experienced two patients with recurred huge cholesteatoma of middle ear. They underwent canal wall down tympanomastoidectomy with mastoid obliteration using the TachoSil^® due to the exposure of dura was observed removing the huge cholesteatoma completely. These two cases report show the successful treatment of recurred huge cholesteatoma, for which no recurrence is shown. (J Clinical Otolaryngol 2016;27:322-326)
