抄録

The author made some clinical investigations on 609 cases with the so-called specific abnormal sensation such as feeling of foreign body or stenosis in the area of hypopharynx, larynx, or upper esophagus, but any remarkable inflammatory change, neoplastic processes, or foreign bodies were not found.<br>But, on the contrary, there were many cases whose complaints were considered due to post nasal discharge, hypertrophied pharyngeal tonsils, abnormality of the epiglottis, mild inflammatory changes in the pharynx or larynx, esophagitis in upper segment, spasm of esophageal orifice, abnormal styloid process, and hypochromemia. To these facts, the personaly test of 137 cases showed asthenic personal character in about 80% of them, and the psychiatric examination showed that some of them were thought to be neurosis patients.<br>But among these facts such specific abnormal sensation in hypopharynx was considered to have more important relations with hypertrophied lingual tonsils and spondylosis deformans of the cervical spine. Because, compared with healthy persons, such patients showed very frequently such tonsils and the remarkable spondylosis deformans of cervical spine, especially in the 4th to the 6th. And it is already acknowledged, that persons aged from 30 to 49 years show the ossification of laryngeal cartilages. From these facts it is easily supposed, that the area between the hypopharynx and the esopageal orifice is irritated by various factors.<br>Adding to these facts the author performed some animal experiments on rabbits to resect some of the cricoideal cartilage, and measure the change of the internal pressure of the esophageal orifice during deglutition. After the operation the degree of the change of the pressure was obviously decreased.<br>From the above investigations, the author believes, that for the occurence of the specific abnormal sensation in hypopharyns, some distinct or indistinct changes of the organs related to the deglutition plays an important role.
