A questionnaire to assess olfactory rehabilitation for laryngectomized patients (Provox voice prosthesis users) in Japan

Patient demand for olfactory rehabilitation is strong, but this therapy is not widely offered to laryngectomized patients in Japan. Notably, the SAOQ scores showed that olfactory rehabilitation may have an effect, even if it is initiated after laryngectomy. We believe that when patients choose voice prosthesis for speech, their olfaction deteriorates unless they undergo olfactory rehabilitation separately from speech rehabilitation. It is therefore necessary to administer olfactory rehabilitation for laryngectomized patients who have never received olfactory rehabilitation, as well as for patients scheduled to undergo laryngectomy.
