The field of usefulness of peroral endoscopy as an aid to general diagnosis of diseased conditions in the throat and thorax has increased extensively in recent years.
While specialists in this particular line of work fully appreciate the information which may be obtained by examination with the direct laryngoscope, bronchoscope and esophagoscope, there are many of the medical profession who do not realize how much might be gained by a single endoscopic inspection in many of the obscure conditions affecting the upper air and food passages. So many articles have been written and so much attention has been directed to the foreign body phase of this subject, that the routine use of these instruments for diagnostic purposes in many common diseases is generally unappreciated.
In this paper, several cases showing the practical value of endoscopic examination in an average practice are presented briefly. All unessential details have been omitted
