Control of bleeding is mentioned as an important factor which influences the success or failure of ESS. Within a narrow nasal cavity, a conventional bayonet type bipolar often is difficult to even open the tip by interference. In ESS, the mono-body forceps type tools are very useful. In recent years, many very user-friendly instruments, such as a forceps type bipolar with suction and rotation tip bipolar for skull base surgery, have already been released.
The endoscopic surgery in a nose is expanded even to not only ESS but the nose sinonasal tumor operation, or the skull base operation in recent years, and an exact arrest of hemorrhage is an important point of an operation.
It is also important to gather information in various surgical tools and to choose suitable tools.
