Forty-five surgical procedures were performed for neck nodal metastatic carcinoma of unknown origin (n=3); carcinoma of tonsil (n=2), tongue (n=2), nasopharynx (n=3), maxilla (n=1) and laryngo-pharynx (n=4). Droplet contamination was 57.8%, 59.5%, 8.0% and 0% for operating, first and second assistant surgeons, and scrub nurse respectively. Droplet count was highest and most widespread during osteotomies. No droplet splash was noted for transoral robotic surgery.
