Development of Endoscopic Holder System for Endoscopic Ear Surgery

Objectives/Hypothesis: The objective of this study is to develop a lightweight, rigid endoscopic fixation system integrated into a headset, designed to maintain stability and ensure patient safety even during unexpected head movements. Methods: We developed the endoscopic holder system by combining the advantages of Raman ‘s 2004 Yasargil retractor method and the 2008 headband method. We confirmed the usefulness of this device through cadaveric dissection. Results: A malleable endoscopic holder system, securely fixed on a helmet with a chinstrap, was successfully developed as designed. The system demonstrated excellent adaptability in the cadaveric model, providing a stable and secure fixation of the endoscope throughout the procedures. No technical issues or instability related to the fixation device were observed during the cadaveric dissection. Furthermore, the device allowed for an unhindered two-handed technique, with no interference or collisions between the surgical instruments, ensuring a smooth and precise operative flow. Conclusion: This device addresses the limitation of single-handed manipulation—the primary drawback of conventional endoscopic surgery—by enabling a two-handed technique under a visual field that rivals or surpasses that of a surgical microscope.
