Objectives/Hypothesis Intraoperative recording devices are being increasingly used to provide video for contemporary surgical training. The objective of this study was to evaluate the use of a smartphone as a low‐cost alternative to obtain high‐resolution video from the surgeon's perspective. Study Design A study evaluating the feasibility of using a head‐mounted smartphone with a telephoto lens for point‐of‐view surgical videography. Methods Video recordings of a rhinoplasty procedure were taken using a head‐mounted smartphone and two handheld cameras, a Canon Powershot SD1400 IS and a Sony HandyCam HDR‐CX160. Video clips were shown to 16 blinded otolaryngology residents (n = 10) and attending physicians (n = 6) for individual video evaluation using a Likert scale (1 being poor quality, 5 being excellent quality). In addition, the study participants were asked to select which video clip they preferred when presented to them side by side. Results The iPhone 7 was given the highest overall mean video quality rating of 3.9 ± 0.57 and was preferred over the two handheld cameras by nearly all surveyed surgeons. The Canon Powershot SD1400 IS was given a mean rating of 3.3 ± 1.0 and preferred over the SonyHandyCam HDR‐CX160 by all surgeons. The Sony HandyCam HDR‐CX160 was given a mean rating of 1.5 ± 0.13. Conclusions A head‐mounted smartphone equipped with a telephoto lens provides a novel method to intraoperative surgical recording. The design is simple, low cost, and allows the surgeon to capture fine anatomical detail from the desirable point‐of‐view perspective. Level of Evidence NA Laryngoscope , 129:578–581, 2019
