The majority of the contributions in bronchoesophagology in 1956 have developed in fields other than those connected with otolaryngology. Basic research has been carried out in the allied specialties, but the lack of original work among bronchoesophagologists is deplored, and even clinical observations among bronchoesophagologists were few in the year reviewed.
Hilding1 demonstrated that the mucous blanket in the tracheobronchial tree may be made to impinge upon and accumulate at an artificially deciliated island just as upon an obstruction. The impingement may remain for hours on such an area while ciliary action and streaming of mucous continues in the surrounding areas.Hilding2 also demonstrated that the carina divided the ciliary streams from the two main bronchi in such a way that there was a special concentration of flow on the anterior and posterior walls of the trachea. Both of these were directed upward to the larynx
