Abstract:
Esophageal speech is the first choice for vocal rehabilitation in laryngectomized patients. However, shunt speech is a needed alternative for patients who cannot succeed at esophageal speech. Many kinds of voice prostheses, with good results, have been reported. Provox was selected for 15 laryngectomized patients who were treated in our department. Voice rehabilitation was successful in 13 patients. However, removal of the prosthesis was required in one patient because of stomal stenosis. Voice rehabilitation was not successful in one patient who exhibited esophageal stenosis. The rate of voice rehabilitation was not influenced by the extent of surgery, the dose of radiation, etc.. The maximum phonation time was more than 10 minutes in the 13 patients who succeeded at shunt speech. Prosthetic rehabilitation was requested by two patients who had been successful at esophageal speech. These results suggest that prosthetic voice rehabilitation may be indicated for a wide range of conditions.
