We introduce advances on transcanal endoscopic ear surgery (TEES) developed in Japan Otological Society.Transcanal Endoscopic Ear Surgery (TEES) has further developed and expanded in the intervening years beyond its initial scope and is now used to treat not only middle ear diseases, but also facial nerve disorders.1) Now large and chronic tympanic membrane perforations usually fail to heal. However, the possibility of repair suggests that it might be feasible to close even chronic and large TMPs by providing suitable conditions for growth and regeneration. Prof.Kanemaru developed TEES combined with regenerative treatment for tympanic membrane perforation using basic fibroblast growth factor (bFGF) , gelatin sponge and fibrin glue.2) Prof. Kakehata developed a facial nerve regeneration treatment for patients with severe Bell s palsy (ENoG of 5% or less), in which a less invasive TEES was utilized. bFGF was applied to the tympanic segment of facial nerve, exposed via TEES, daily for 8 days through the drug delivery route which was made via TEES. 3) When confirming the ossicular fixation, the ossicular mobility is checked by touching them with the needle. This procedure is subjective and non-quantitative, as it is determined solely by the surgeon’s feel transmitted. Therefore, there may be variation in the ossicular mobility value that surgeon decides that an ossicular reconstruction should be performed. Furthermore, the palpation must be performed without exerting significant pressure on the inner ear. However, it is not known how much pressure is applied to the inner ear by the palpation technique. Dr.Kanzaki investigated how much force is exerted on the inner ear by palpation of the ossicles affects the inner ear and the ossicular mobility to determine if ossicular reconstruction is performed.
