Abstract
Dissecting surgical specimens from the upper aerodigestive tract is often difficult because of their complicated anatomy. The local environment dictates the routes of tumour spread and surgical margins at risk, and these features differ for various subsites within this part of the body. The examination of surgical specimens of the upper aerodigestive tract should disclose whether postoperative adjuvant treatment is needed and allow the evaluation of preoperatively performed diagnostic imaging. The aim of this article is to provide a concise guideline for the dissection of specimens from this part of the body.
