Abstract
|
|
|
Objectives: The purpose of this study is to investigate the prevalence and the types of sinus abnormalities in a non-ENT population and draw any clinical correlation between the two phenomena. Materials and Methods: We prospectively
evaluated a total 120 patients who underwent brain magnetic resonance imaging(MRI) for suspected intracranial diseases from March to July 1997, in another department at Kang-buk Samsung Hospital. Patients who had been treated for nasal or sinus
diseases
and who had previous history of nasal or sinus operations were excluded. The sinus abnormalities found on MRI were classified into 6 types as follows ; normal, mucosal thickening less than 3 ㎜ and more than 3 ㎜, fluid collection, polyp or cyst,
and
others. Results: Among 96 patients studied, 42(43.7%) patients showed abnormality in one or more sinus group ; 12(20.7%) of the 58 asymptomatic patients and 30(78.9%) of the 38 symptomatic patients. Sinus abnormalities were most commonly
observed
in the maxillary sinus. Most common abnormality was the mucosal thickening less than 3 ㎜. Conclusion: Incidental sinus abnormalities detected in a non-ENT population were relatively common. However, pathologic condition which demanded
treatment
among these abnormalities were rare. Therefore, it would be important to be careful not to overestimate these signs, and one should evaluate their clinical correlations through complete physical examinations before applying any treatment for
these
lesions.
