ABSTRACT
There are many methods for diagnosis and evaluation of maxillary sinus disease. The PNS radiography is the general method to diagnose the lesion of sinuses. A series of 62 patients (100 sinuses) with acute and chronic maxillary sinusitis evaluated at the department of otolaryngology, Korea University Hospital from November 1, 1989 to February 28, 1991 was reviewed for the diagnostic accuracy of the plain X-ray compared to that of the puncture and irrigation (P & I).
The results were as follows;
The positive rate was 60% in 100 cases of maxillary sinus, especially in 84 cases exception of 12 minimal mucosal thickening and 4 polypoid apearance, the positive rate was 71.4%.
The false-positive rate in plain X-ray was as follows; 16.7% in molderate to severe mucosal thickening, 32.5% in diffuse homogenous opacity, 35% in air-fluid level.
The capacity of maxillary sinus was as follows ; Average 6cc in positive cases of moderate to severe mucosal thickening and 15cc in false-positive cases. Average 8cc in positive cases of air-fluid level and 9cc in false-positive cases.
The accuracy in cases of abnormal nasal cavity findings such as septal deviation, conchal hypertrophy, nasal polyp was 68.2% and in normal nasal cavity, the accuracy was 44.4%
In conclusion, though the plain X-ray is useful diagnostic tool, it is necessary to use endoscopy, ultrasonography and CT scan for evaluation of the maxillary sinus diseases.
