Abstract
Background: To determine the role of conventional
radiography (R.G) in diagnosis of chronic maxillary
sinusitis (CMS) and the common pathogens involved.
Method: This cross sectional analytical study was
conducted at Holy Family Hospital Rawalpindi over a
period of two years. 25 out-door patients with signs and
symptoms of CMS were included. X-Ray views of sinuses
were obtained. Bilateral antral lavage (A.L) was done and
the 50 sinuses evaluated. Mucopurulent irrigations were
considered positive and sent for culture sensitivity.
Results of antral lavage were compared with radiography.
The patients were divided into four groups: True positive
(T.P), False positive (F.P), True negative (T.N) and False
negative (F.N). CMS was diagnosed if clinical features
matched the positive A.L irrespective of R.G. Specificity
of radiography (T.P and T.N results) was differentiated
from its sensitivity. Most prevalent pathogens and their
association with RG was determined.
Results: Forty (80%) out of 50 sinuses were positive
on radiography (sensitivity of R.G). Thirty-four (68%)
gave positive and 16 (32%) gave clear washouts. T.P
results were 25 (50%), T.N results were 02 (4%), F.P were
14 (28%) and F.N were 9 (18%). 21 out of 25 patients
showed positive antral lavage leading to confirmation
of diagnosis in 21 (84%) cases. Specificity of radiography
was 54%. Most prevalent pathogens found were anaerobes.
The sinuses infected with anaerobes were either clear or
showed mucosal thickening on R.G.
Conclusion: Diagnosis of CMS should not be based
on conventional radiography alone. It may only be used as
an adjunctive tool by correlating it with the patients’
symptoms and signs and evaluation by antral lavage
