The enigma of post‐radiation edema and recurrent or residual carcinoma of the larynx

Abstract
Persistence of significant edema of the larynx beyond six months after completion of radiotherapy presents the lavyngologist with a diagnostic dilemma. Review of the results of 43 cases demonstrated a high incidence of residual or recurrent carcinoma. Based upon this experience earlier and frequent laryngeal biopsies are recommended for these cases.
