X-ray Mucous Membrane Function Test (X. M. F. T.)에 의한 만성 상악동염의 진단법 = A Diagnostic Method of the Chronic Maxillary Sinusitis by the X-Ray Mucous Membrance Function Test (X. M. F. T.)

다국어 초록 (Multilingual Abstract)

The X-ray Mucous Membrane Function Test (X. M. F. T.) is a method of evaluating the functional capacity of the ciliated epithelium of the mucous membrane of the sinus and grade of pathological changes in the tunica propria by demonstrating the images cast by the contrast material (2.5cc of 20% moljodol) injected into the maxillary sinus. This method is essentially different from the conventional simple X-ray studies, because it is able to observe presence and character of the contents within the sinus cavity and also to visualize the sinus orifice and extrasinus structures. The authors performed a modified X-ray Mucous Membrane Function Test (central ray was directed 15。 cauded in erect lateral view) to the patient in whom chronic maxillary sinusitis was suspected clinically during the period of 7 months from February 1975 to August 1975. There results obtained were as follow: 1. A total number of the patient received X. M. F. T. was 90 and sex distribution was 54(60%) males nd 36(40%) females. Most of the patient (82.2%) was distributed in 11-40 years of age and peak incidence (40%) was in 11-20 years of age. 2. Among a total of 90 patients, bilateral X. M. F. T. was performed in 75 patient and unilateral in 15 patient. In a sum of 165 maxillary sinuses, 79 cases (47.88%) were on the right side and 86 cases (52.12.%) were on the left side. 3. Takahashi's classification of moljodol X-ray images, i.e. A) complete diffusely spread type, B) incomplete diffusely spread type, C) spotted type, D) diffuse localized transitional type, E) localized type, F) scattered type were observed in our cases. But we recognized G) non filling type, which Takahashi did not mention. It was due to severe chronic maxillary cinusitis, extensive malignancy and postoperative state of Caldwell-Luc operation. Among 7 basic types, incomplete diffusely spread type (31.5%) and diffuse localized trasitional type (24.2%) showed higher incidence. 4. In analysing the above 7 basic types, t e degree of impairment of the ciliated epithelium of the sinus mucosa was severe in A. B. C. D. E. F. G. in order. 5. The sinus orifice was open in A, B type being mild sinusitis but close in D. E. F. G. type being moderate and severe sinusitis. 6. The incidence of involvement of the other sinuses were higher in D. E. F. G. type than in A. B. C. type and the ethmoid sinus anatomically located near to the maxillary sinus showed higher incidence than the other frontal and sphenoid sinuses. It could be emphasized that X. M. F. T. is a useful method for early detection of maxillary cancer and also could indicate a therapeutic approach to each type of sinusitis to E. N. T. doctor.
