Between 1973 and 1977 seven adults and five children with severe larynx stenosis were operated upon successfully with a modification of Rhéti's technique. The main features of this new technique are: 1. The cricoid and the upper tracheal rings are split longitudinally in their anterior and posterior portion. 2. The stabilisation of the enlarged laryngeal lumen by the interposition of a piece of notched costal cartilage in the posterior wall of the split cricoid.
