Background: The most critical exam components in patients seeking rhinoplasty have not been established. Objective: To identify concordance among experienced rhinoplasty surgeons regarding the most important exam features for various deformities. Methods: An online questionnaire was distributed to board-certified facial plastic and plastic surgeons experienced in rhinoplasty, with seven nasal deformity categories: dorsal hump, crooked nose, boxy tip, pinched tip, droopy tip, saddle nose, and nonallergic nasal obstruction. For each, respondents were asked to rank the three most important anatomic regions to examine from the following: nasal bones, midvault cartilage, skin, radix, facial profile, lip, tip, septum, internal nasal valve, nostrils, inferior and middle turbinates. For each ranked region, up to three important features were chosen. Normalized Attention Scores (NAS) were calculated to determine agreement amongst surgeons. Results: A total of 13 facial plastic and 8 plastic surgeons were invited to participate and completed the questionnaire. All cases had high agreement demonstrated by NAS, with the dorsal hump case exhibiting the greatest variability in responses. Conclusions: In this survey of 21 rhinoplasty surgeons, there was general agreement regarding the most relevant anatomical structures and features, which may provide a conceptual foundation for identifying key exam features for seven common complaints in patients seeking rhinoplasty.

Background: Facial appearance influences social perception, with laypersons focusing on the central facial triangle; nasal differences may alter gaze patterns, but few studies have quantified this using eye-tracking. Objective: To evaluate how layperson gaze patterns shift in response to different nasal variations as measured by eye-tracking. Methods: In this prospective cohort study, facial images with 30 nasal differences were created using Photoshop to represent a range of phenotypes, such as dorsal hump, crooked nose, and pinched tip, alongside controls. Gaze data were captured via eye-tracking, and linear mixed-effects modeling assessed differences in time spent viewing defined areas of interest, adjusting for participant and image variables. Results: A total of 119 participants (53.8% female) were enrolled. The median age was 40 years, and 82% identified as Caucasian. Among the 30 nasal alterations, only the saddle nose resulted in significantly increased gaze time compared to controls (mean increase: 0.89 s; p < 0.001). Participant age, sex, and gender of the face in the image did not significantly influence gaze behavior. Conclusion: In this study, only the saddle nose attracted greater visual attention from lay observers compared with other nasal variants.

Introduction: Nasal analysis is a challenging skill that otolaryngology trainees must demonstrate competency in on-board examinations. Study objective: To compare where experts and trainees focus their gaze when completing nasal analysis of a patient, as measured by eye tracking software. Methods: Participants of various training levels ( n = 27) were shown photographs of six faces from all standard angles for photographic nasal analysis. Eye-tracking data were collected. Heat and gaze maps, the time to first fixation on areas of interest, duration, and number of fixations were extracted. These metrics were compared between experts and trainees using t -tests and one-way ANOVA. Results: Qualitative comparisons of gaze patterns reveal a more comprehensive and organized approach among experts than trainees. However, quantitative measures of eye-tracking metrics, including the time to first fixations, duration, and number of fixations made by experts and trainees, were similar. Conclusions: Gaze tracking reveals more thorough and efficient eye movements among experts than trainees during nasal analysis. Further study may be useful in the development of learning tools to guide effective nasal analyses.
