Abstract
The causes of pharyngo-laryngeal paresthesia are variable. The abnormal sensation occurs not only by single cause but by many complicating factors, reversible or irreversible.
Consequently we divide the causes into intrinsic and extrinsic factors. The former points to physical constitution of patients, such as sex and age, and the latter points to pathological changes elicited and described by us.
They take part together in preparing the condition, especially psychological motivation inpluences the abnormality. We propose the causee from our own clinical cases.
