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）相关口咽癌正在增加，在男男性行为者中发病率很高。HPV相关癌症的优势在于，通过口咽视诊经常可检测到，且生存率比经典口咽癌高得多。已有研究表明，男同性恋者和双性恋男性可以拍摄质量足以用于筛查的口咽“自拍”。然而，存在一个问题，即舌头无法移动，难以清晰看到腭扁桃体，而大多数口咽癌病例都发生在此处。我们试图研究使用市售视频喉镜观察口咽的可行性。14名健康志愿者使用提供的低成本商用内窥镜对其口咽进行录像。参与者将视频喉镜连接到笔记本电脑上，能够在屏幕上看到口咽。观察尝试过程并做记录。之后立即组织参与者进行焦点小组讨论，以确定使用视频喉镜的障碍和促进因素。所有参与者都能够使用视频喉镜并获得清晰度足以看清主要口咽标志的视频。起初，由于无法充分控制舌头，腭扁桃体难以看清。给参与者时间练习使用视觉线索来控制舌头位置，这有助于获得清晰的视频。视频喉镜只需极少的指导就能有效使用，并且由于能照亮和放大观察部位，比静态图像能提供更好的视野。低成本的市售视频喉镜可能比智能手机“自拍”效果更好。
