The author presented a review of recent foreign literature on serous otitis media with special reference to etiology of the diesease. Although stenosis of the eustachian tube had been considered to be the main factor of the disease after Politzer, recent studies seem to suggest that infection plays important role in the development of the disease.
The frequency of chondrosarcoma has been reported as 7% of all bone and cartilage malignancies in Japan, 11.3% in the United States as reported by Dahlin at Mayo Clinic, and 24.1% in Netherland according to the report from Committee on Bone Tumors. The pelvic bones and femur are the sites of frequent occurrence while involvement of the otolaryngological areas is considered to be relatively rare as is seen in a report that the frequency of chondrosarcoma was 0.3 of all malignancies and 2.9% of all sarcomas in the otolaryngological area. A search of Japanese literature revealed 58 cases of head and neck sarcomas since the initial report made in 1917 by Kobayashi, of which 7 cases were chondrosarcoma of the nasal septum. The authors discuss the rare case of chondrosarcoma of the nasal septum in comparison with other cases reported in the literature.
Antroscopy has been carried out by the authors using a new serfoscope of 1 mm diameter which can be introduced into the maxillary sinus through a cannula penetrated into the sinus via the lower nasal meatus. This type of endoscopy of the maxillary sinus is quite beneficial as it gives detailed information of the condition inside the cavity, thus permitting the corrrect selection of treatments. Color photography insidethe cavity can be taken during the procedure. Comparison of the findings obtained during sinuscopy and those obtained by radiological andhistological examinations in chronic maxillary sinusitis is discussed.
The authors report three cases of plasmacytoma, one extramedullary plasmacytoma and the othertwo multiple myelomas. The first case developed in the nasopharynx, the second case in the right frontal sinus and the thirdin the larynx. The diagnoses of the 3 cases were confirmed by histopathological, radiological and biochemical studies. The 3 cases were treated by MIP therapy (Melfaran, Ifosfamide and predonine) and irradiation. The authors recommend radiation therapy even for cases of extramedullary plasmacytoma in orderto prevent local recurrence and metastasis.
