The following case, reported elsewhere by one of us,1 gives some idea of the practical importance of this subject:
In 1900 one of my students came to me for an explanation of certain curious phenomena that occurred during massage of an epithelioma of the lower lip. It was about 1 1/4 inches in diameter and surrounded by an indurated area. The center was very sensitive. When this part was massaged the patient cried: "Don't cut my wind off! You are choking me!" He gripped the chair and grew dark in the face, breathing hard, with a pulse of 100, subsiding quickly to 20; respiration about 12. Massage next day caused the same alarming symptoms.
No doubt it was a case of reflex inhibition caused by mechanical stimulation of the abnormally sensitive endings of the trifacial.
Reflex inhibition has not received from laryngologiste the attention it deserves. The text-books
