Abstract:
Objective: To evaluate the diagnostic accuracy of ultrasound in maxillary sinusitis keeping computed tomography as a gold standard.
Methodology: This is a Cross-Sectional validation study that prospectively included cases of suspected maxillary sinusitis using a convenience sample. A sample of either gender, above 10 years age was recruited from otolaryngology and radiology departments of Capital Hospital, Islamabad, Pakistan from December 2019 to February 2020. Computed tomography imaging of Paranasal sinuses and Ultrasound of Maxillary sinuses were used for data collection. Data was analyzed using SPSS Ver-23 and test sensitivity, specificity, PPV and NPV, and Accuracy Rate were calculated.
Results: The sample comprised 27(45%) males and 33(55%) females with a majority 31(51.7%) of the patients being 36-50 years old. Ultrasonography was calculated to have a sensitivity of 96.4% for diagnosing sinusitis, however, its specificity was only 25%, while the accuracy rate was 93.22%. The PPV of ultrasonography was 94.7%, while the NPV was 33.3%.
Conclusion: Ultrasound with an accuracy rate of 93.22% and a sensitivity of 96.4% has benefits of safety, easy availability and low cost and hence is an important investigation for maxillary sinusitis evaluation.
