Innumerable articles have been written on the subject of pharyngeal diverticula since Ludlow, in 1764, first drew attention to this condition.
It is not the object of this paper to discuss features to which attention has been drawn on many occasions, but to analyze, firstly, the suggestions which have been advanced as being factors in the production of pharyngeal pouches, and, secondly, to suggest a technique of operation which in our view not only makes operation far simpler but also makes the end-result more certain and permanent.
