Human papillomavirus (HPV)-related oropharyngeal cancers associated with sexual contact are increasing, with high rates in men who have sex with men. HPV-related cancers have the advantage of being frequently detectable through oropharyngeal visual examination and having much higher survival rates than classic oropharyngeal cancers. It has been demonstrated that gay and bisexual men can take smartphone oropharyngeal "selfies" of sufficient quality for screening. However, there is an issue with the inability to move the tongue to allow a clear view of the palatine tonsils, where a majority of oropharyngeal cancer cases occur. We attempted to investigate the feasibility of using commercially available videoscopes to visualize the oropharynx. Fourteen healthy volunteers used a provided low-cost commercial endoscope to video their oropharynx. Participants used the videoscope connected to a laptop and could visualize the oropharynx on the screen. Attempts were observed, and the process was noted. A focus group of participants was carried out immediately afterwards to ascertain barriers and facilitators to using the videoscopes. All participants were able to use the videoscope and obtain videos of sufficient clarity to note major oropharyngeal landmarks. The palatine tonsils were initially difficult to visualize because the tongue could not be sufficiently controlled. Participants were given time to practice using visual cues to control the position of the tongue, which helped in obtaining good videos. Videoscopes can be used effectively with minimal instruction and provide a better view than still images, as they illuminate and magnify the site. Low-cost commercially available videoscopes may be an improvement over smartphone "selfies".

与性接触相关的人乳头瘤病毒(HPV)口咽癌正在增加,在男男性行为者中发病率很高。人乳头瘤病毒相关癌症的优点是经常可以通过口咽部肉眼检查发现,而且存活率远高于传统的口咽部癌症。事实证明,男同性恋者和双性恋者可以通过智能手机拍摄质量足够高的口咽 "自拍照",用于筛查。但是,有一个问题是无法移动舌头,无法清楚地看到腭扁桃体,而大多数口咽癌病例都发生在腭扁桃体。我们试图研究使用市售视频镜观察口咽部的可行性。14 名健康志愿者使用提供的低成本商用内窥镜对口咽进行录像。参与者使用的内窥镜与笔记本电脑相连,可以在屏幕上看到口咽部的情况。对参与者的尝试进行了观察,并记录了过程。紧接着对参与者进行了焦点小组讨论,以确定使用视频镜的障碍和促进因素。所有参与者都能使用视频窥镜,并获得足够清晰的视频以记录主要口咽地标。腭扁桃体一开始很难观察到,因为无法充分控制舌头。参与者有时间练习使用视觉提示来控制舌头的位置,这有助于获得良好的视频。只需少量指导就能有效使用视频显微镜,而且由于视频显微镜能照亮和放大观察部位,因此能提供比静态图像更好的观察效果。低成本的商用视频镜可能比智能手机的 "自拍 "更好用。
