[Severe laryngeal stenoses in adults. Results of the Réthi-Ward enlarging technic].

Treatment of severe cricoid stenosis with fixed vocal cords is difficult, the often used Réthi operation producing 20 to 30% of unsuccessful results. Use of a hyoid bone pedicle flap allows anterior enlargement with cricoid ring reconstruction, in addition to the classical posterior enlargement, and was successful in 8 of 9 cases treated by this method.
