Technique and clinical importance of eustachian tube radiography.
The intact eustachian tube is essential for a successful tympanoplasty. Since clinical function tests do not provide satisfactory results in every case, radiologic examination of the tube becomes very significant. The technique, which we have employed since 1966 in sixty-seven cases of transtympanic radiography of the eustachian tube, is described. The most important indications for this examination are discussed (cases of chronic middle ear suppuration, post-traumatic tube stenosis, and early diagnosis and clarification of tumors of the nasopharynx and middle ear). The transtympanic method is physiologic, simple to perform, and essential for hearing improvement.
