Chondrosarcoma, as the name indicates, is a malignant tumor of connective tissue origin arising from cartilage. In 1952, Lawson! reported the clinical and pathological findings of a 76 year old woman treated by surgery and x-ray therapy for a chondrosarcoma apparently arising in the nasal septum, filling the right side of the nose and extending into the right maxillary sinus. Ten years earlier, a chondroma had been removed from the left side of the nose.

Crowe (1) called attention to the fact that lymphoid tissue in the nasopharynx, especially the lateral parts, could, as the result of hypertrophy and hyperplasia, cause intermittent or constant blockage of the nasopharyngeal orifices of the eustachian tubes. He noted that such blockage interfered with the normal ventilation of the middle ear cavity and was reflected, most often in children, in decreased hearing. The examination of the ear drums revealed retraction of the tympanic membrane and a reddish blush from the edematous mucosa of the medial wall of the tympanic cavity. Examination with an electric nasopharyngoscope showed actual encroachment of the lymphoid elements on the mouth of the eustachian tube. It was evident that surgical extirpation of the oral and nasopharyngeal lymphoid structures, no matter how complete, could not reach the laterally placed portions in the fossae of Rosenmuller and about the lips of the tubal orifice without causing serious damage to the mucosa and nearby anatomic part...

AS a general rule, radiograms are taken mainly with the idea in mind of making a diagnosis for surgical or non-surgical interference, but the study of X-ray films after operation has been neglected or treated lightly and only in gross errors or medico-legal cases have they been called into play. Then, too, the number of monographs in the literature which deal with diagnosis of diseases of the head and neck by the radiogram is relatively small. This is especially true if one takes into consideration only the publications of those authors who have broad experience of the clinical and pathologic entities in this field. There can be no doubt that radiography of the head, when properly undertaken, is distinctly a science—a branch of medicine of the utmost importance—but it can rightfully be said that knowledge of the pathologic conditions and of their clinical values is by no means the common property of all physicians. What is meant by the pre-and post-operative study of radiograms? Since we are discussing wh...
