Abstract:

Objective  To explore relative factors affecting dysphonia of the Blom-Singer pronunciation tube.  Methods  The clinical data of 108 patients who had undergone Blom-Singer voice producing reconstruction following total laryngectomy were retrospectively analyzed. 96 cases received stage Ⅰ Blom-Singer voice producing reconstruction, and the other 12 cases underwent stage Ⅱ Blom-Singer voice producing reconstruction.  Results  22 of 96 cases who had undergone stage Ⅰ Blom-Singer voice producing reconstruction had less effective phonation(22/96, 23%), and 8 of 12 cases who had undergone stage Ⅱ Blom-Singer voice producing reconstruction did not get the expected voice(8/12, 67%), and the total failure rate of the two operative methods was 28%.  Conclusion   The successful rate of stage Ⅰ Blom-Singer voice producing reconstruction was higher than that of the stage Ⅱ Blom-Singer voice producing reconstruction. Effect of voicing quality after the operations was closely related to following factors, such as treatments to the cricopharyngeal muscle,  integrity of the tracheoesophagus wall,  size of the trachea stoma, pharyngeal fistula, stenosis of the esophagus hypo-pharyngeal cavity and pulmonary function of patients.
