A survey regarding post-laryngectomy olfaction was conducted on 17 patients. 12 patients expressed the ability to smell after laryngectomy. All of five patients who had esophageal voice and five of 10 patients who had electrolaryngeal voice stated that they could smell. The post-operative period before patients indicated that they could smell ranged from 0 to 5 years. These patients who claimed the ability to smell could not do so with complete function. 11 patients (65%) hoped to regain normal olfaction.<BR>In order to achieve this goal, we manufactured a tool to restore the capability of smelling. Utilization of this tool is projected to restore normal nasal airflow and to improve the olfactory threshold. This tool offers an invaluable improvement of the quality of life of patients that have undergone laryngectomy.
