The investigation and management of non-neoplastic diseases affecting the salivary glands

IT is a great honour for me to have been appointed as the Semon lecturer of the year. I feel very humble to be in the same line as famous laryngologists like Professor Killian, Dr. Mosher, Professor Hajek, Sir Victor Negus, Professor Nager, Professor Ormerod, Lord Adrian and Professor Portmann. These and others have given so much to the knowledge of otolaryngology that my own contribution seems very small in comparison. I feel still more humble after reading the story of Sir Felix Semon. It gives you the portrait of a great man who, thanks to his personality, reached a leading position from where it was possible to have a world-wide influence. He used this to transform otolaryngology into a foremost speciality. My topic today has been handled once before and not so long ago in a Semon lecture by Mr. Patey from London. It may be noteworthy that Mr. Patey is a general surgeon and that the salivary glands have come into the field of otolaryngology only during the last decade. In some countries they are still outside the field. In Sweden, however, Otolaryngology took over the diseases of the salivary glands in the late forties when the treatment of parotid tumors at the Karolinska Hospital was transferred from the General Surgical Department to the E.N.T. department, led by Professor Skoog. This paper will be devoted solely to the non-neoplastic diseases of the glands. In this way I exclude the more, let us say, dangerous part of the salivary gland disorders. On the other hand the views on the tumors of the salivary gland are much more conformative and therefore perhaps less interesting to discuss. This, of course, does not mean a general agreement on their diagnosis, pathology and treatment. One may state that the non-tumorous lesions of the salivary glands are seldom a danger to life, but they may be very distressing not only because of the pain they may cause, but also because of the disagreeable dryness that many times is an important symptom. Because of the relatively innocent character of the diseases, the interest in them has been slight and the sufferers have very often been left without help. In fact, fairly few doctors have shown any interest in these diseases and patients
