Abstract
Transcanal endoscopic ear surgery (TEES) is a minimally invasive surgical treatment technique for middle ear diseases and is recently becoming popular around the world. TEES enables accurate surgical manipulation under a wide magnified, and clear surgical view. We describe the results of surgical treatment for congenital middle ear anomalies by comparing the hearing outcomes between patients treated by TEES and those treated by microscopic ear surgery (MES). Congenital middle ear anomalies were safely treated by TEES, with comparable hearing outcome to those after MES. The surgical field is limited in the tympanic cavity, inflammation is usually absent, and there is little bleeding during the operation; therefore, TEES is a feasible surgical approach for the treatment of congenital middle ear anomalies. However, as middle ear anomalies are diverse, preoperative diagnosis is sometimes difficult, and the surgeon must be adequately prepared in advance for various types of procedures.
