[Treatment of subglottic stenoses using the Pearson's operation: apropos of 3 cases]

Surgery of stenoses of the laryngo-tracheal junction is governed by the necessity of maintaining the support of the cricoid-arytenoid articulations and of preserving the recurrent nerves. Sub-total cricoid resection with conservation of the recurrent nerves, known as Pearson's operation, enables the treatment of fixed sub-glottic stenoses with mobile larynx. On the basis of three recent observations, the authors define the indications and the performance of this surgery. The respiratory and vocal results are considered satisfactory in these three cases.
