Intraoperative specimen-driven assessment of resection margins as frozen section diagnosis and videoconference-based evaluation in head and neck carcinomas

Introduction Resection status has high prognostic and therapeutic relevance in the treatment of head and neck carcinomas. For the evaluation of the R-status, the assessment of resection margins on the intact resection specimen shows the best reliability. If this method is performed intraoperatively as frozen section diagnosis, it is associated with a higher time and personnel expenditure and is therefore only used in a few clinics.
