title: Primary conversion laryngectomy: success in failure.
abstract: The concept of surgical exploration for conservation surgery has been applied to selected advanced and radiation failure laryngeal and hypopharyngeal cancers. Primary conversion laryngectomy was required in 50 patients. Factors affecting evaluation, therapy, and survival have been examined. The exploration proves valuable in exactly documenting disease extent and preserving a maximum number of larynxes without adversely affecting survival.
