Research opportunities at the Institute of Laryngology and Otology, London.

Emphasis is placed on the need to encourage original research in our training programs. This implies an obligation to help trainees inexperienced in research to bridge the gap between theory and practice. Four examples of patterns of research at a postgraduate institute are presented. All are in areas in some way relevant to carcinoma of the larynx: a) the effect of experimental hypothermia on transplanted tumors in rats; b) isotope detection of deep vein thrombosis following head and neck surgery; c) stomal calibre after laryngectomy related to airflow, esophageal voice and cineradiographic appearances; d) a case-controlled study of the etiologic role of asbestos in laryngeal cancer. These studies are still in progress but some preliminary observations can be reported.
