ABSTRACT
BACKGROUND AND OBJECTIVES: In recent years, surgical imaging has become important for legal and educational purposes. Significant improvements can be made from the surgeon's point of view in recording surgical procedures, particularly with respect to the action camera with high-definition video recordings. For otolaryngologic surgery, the surgical view is narrow, and there is a limit to proper imaging using the existing lens of the action camera. Therefore, we aimed to find out if we could obtain surgical images through simple modification of action camera. MATERIALS AND METHOD: The action camera was modified to match the surgical field. We selected a suitable lens for otolaryngology surgery using a calculation formula. The action camera was simply modified according to the design. The modified action camera can be mounted on the surgeon's head or the surgical light. We compared the images taken with the modified action camera and the images taken with the existing camcorder. The modified action camera was able to capture a narrow surgical field for otolaryngologic surgery. RESULTS: Unlike the existing method, we were able to obtain high-quality images using a modified action camera at the first person's viewpoint without auxiliary manpower. The action camera was considerably cost effective compared to other methods of recording surgery. CONCLUSION: The modified action camera allows for high-definition, cost-effective, and firstperson viewpoint for otolaryngologic surgery. The modified action camera allows for detailed videography that can enhance surgical teaching, presentation and patient education materials.
