Ear, nose, and throat (ENT) surgeons often perform multiple daily procedures requiring sustained postures while wearing headlights or loupes, increasing the risk of work-related musculoskeletal disorders (WMSDs). This in situ case study aimed to (1) evaluate ENT surgeon workload and (2) introduce ergonomic interventions through workflow changes, education, and personal protective equipment. Three trained ergonomists observed the intraoperative workflow of three ENT surgeons at a tertiary academic hospital, identifying awkward postures. Surgeons received education on surgical microbreaks and OR-Stretch before trialing passive exoskeletons. Exoskeleton effectiveness was evaluated using interviews and surveys. Workflow interventions improved neck posture. One surgeon reported reduced body-part discomfort but increased subjective workload when using the exoskeleton, while interviews identified aesthetic concerns. This exploratory case study identified workflow issues and introduced ergonomic interventions. Although one surgeon reported reduced discomfort with an exoskeleton, larger studies are needed to establish quantitative trends.
