Fixation devices for ear endoscopes have also been designed by several researchers since the mid 2000s when surgery became popular. Most of these devices are table-fixed type. However, unlike the abdominal cavity or upper and lower extremities, table-fixed otoendoscope may cause fatal damage to the inner ear structures or even death due to the CNS damage during unexpected sudden movement of the patient. The purpose of this study is to develop a lightweight and rigid endoscope fixation device which is secured to the headset and is safe for sudden movement of the patient.

– Study Design: Development of endoscope holder system
– Setting: We developed the endoscopic holder system by combining the advantages of Raman ‘s 2004 Yasargil retractor method and the 2008 headband method.
– Intervention(s): We used this system for cadaveric dissection and analysed the usefulness of this endoscopic holder system.

– Main Outcome Measure(s): The endoscope holder developed in this study enables the endoscope to be fixed by wearing a helmet on the head of the patient to prevent the patient from being injured by sudden movement during operation, which is a disadvantage of the conventional operation table fixed or microscope mounting type.
– Results: We developed a novel endoscopic holder system fixed on helmet(headband) with chin strap.
– Conclusion: This device will solve the inconvenience of one hand operation, which is the biggest disadvantage of endoscopic surgery, so that it will be possible to operate with both hands in a better visual field than the microscope.
