Background: Although all microsurgeries are based on the use of surgical microscopes, several alternative magnification systems have shown promising results. Improvements in image quality facilitated the use of video systems in microsurgeries with safety and accuracy. The aim of this study was to evaluate the use of a low-cost, video-assisted magnification system in peripheral neurorrhaphy in rats. Methods: Twenty Wistar rats were randomly divided into 2 matched groups according to the magnification system used: the microscope group, with neurorrhaphy performed under a microscope with an image magnification of 40×; and the video system group, with the procedures performed under a video system composed of a high-definition Sony camcorder DCR-SR42 set to 52× magnification, macro lenses, 42-inch television, and a digital HDMI cable. We analyzed weight, nerve caliber, total surgery time, neurorrhaphy time, number of stitches, and number of axons in both ends (proximal and distal). Results: There were no significant differences between groups in weight, nerve caliber, or number of stitches. Neurorrhaphy under the video system took longer (video: 5.60 minutes; microscope: 3.20 minutes; P < .05). Number of axons was similar between groups, both in proximal and distal stumps. Conclusion: It is possible to perform a peripheral neurorrhaphy in rats through video system magnification, but with a longer surgical time.

AbstractObjective:This study aimed to estimate the effectiveness of a full digital, high definition video system for laryngeal observations.Methods:A newly available, full digital, high definition video camera and high definition video monitor were used. With an endoscopic adaptor and rigid telescope, laryngoscopy and stroboscopy were performed on patients with various kinds of laryngeal lesions.Results:All laryngeal lesions were observed and recorded by the full digital, high definition video camera without incident. The image quality for laryngoscopy and stroboscopy was far superior to that of a conventional video system, including video-endoscopy. Even tiny structures or lesions could clearly be visualised on the monitor. The still image obtained from the full digital, high definition video camera was 1920 × 1080 pixels and was comparable to that obtained from a still camera.Conclusions:Full digital, high definition video cameras are now commonplace products and can easily be applied to patients with laryngeal disorders. They provide superior laryngeal images, compared with conventional video systems. Furthermore, high definition video systems are cheaper than proprietary medical video systems. We consider our system to represent an accessible technique of gaining superior laryngeal observation in otolaryngological clinics.
