Close cooperation between those involved in clinical treatment and pathology is imperative in head and neck surgery, as in all surgical fields. The degree of cooperation depends, on the one hand, on the knowledge that the head and neck surgeon has about the possibilities and limits that confront the pathologist, and on the other hand, on the knowledge that the pathologist has about the special problems of head and neck pathology and their management by the surgeon. Within the last 15 years, the knowledge of larynx growths and their treatment has changed rapidly. Parallel to this increase in knowledge, the technical possibilities in histopathology have also increased. For this reason, the authors of this volume present an up-to-date view of the whole scope of the pathology and clinical treatment of larynx tumours.
