Abstract

Objective: The objective is to conduct a questionnaire survey regarding pharyngolaryngeal sensation evaluation in dysphagia to understand the current situation in Japan. Method: The questionnaire was sent to the councilor of the Society of Swallowing and Dysphagia of Japan and the Japanese Society of Dysphagia Rehabilitation-Certified Clinician. The prospective questionnaire survey included the questions listed below: Q1: What do you think of the importance of pharyngolaryngeal sensory evaluation? Q2: Select one of the essential swallowing sensations. Q3: Select one of the following regarding the frequency of sensory examination of the larynx. Q4: Select the proportion of cases the sensory test results affect. Q5: As a pharyngolaryngeal sensory evaluation method in swallowing function evaluation, please fill in the table below for the frequency, difficulty, and effectiveness of the following tests, such as gag reflex, touching the larynx by endoscopy, touching the larynx by the probe with endoscopy, cough reflex test, swallowing provocation test. Results: The essential swallowing sensations of mechanical stimulation, chemical stimulation, thermal stimulation were 84.9%, 5.4%, and 9.7%, respectively. The frequency of touching the larynx by endoscopy in the otolaryngology group and cough reflex test in dentistry was significantly higher than the other groups (p < 0.05). The correlation between the frequency and difficulty or effectiveness of the sensory tests indicated that the frequency and difficulty are significantly correlated between each item. Conclusion: Our results aid in increasing understanding and selection of pharyngolaryngeal sensation evaluation for dysphagia patients.
