Role of Ultrasonography and Conventional Radiography in the Detection of Maxillofacial Fractures: A Comparative Study

Abstract

Objective: With the collaboration of the trauma department, our study was designed to compare the effectiveness of ultrasonography (USG) and conventional radiography in the detection of bony fractures related to oral and maxillofacial regions. Methodology: This comparative study was conducted from March 2020 to March 2021 by the Radiology department of Sarghoda medical college hospital with the collaboration of the trauma department. Ultrasonography was performed by using GE- USG machine along with a linear extraoral transducer (frequency range 7-15 MHZ). Patients were asked to sit in a seated position facing the sinologist. Transducers were placed over the site by applying the sterile gel. Results: The overall sensitivity and specificity rate of ultrasonography was reported as 83.33% and 98.88% respectively in all sites whereas the sensitivity and specificity rate of conventional radiographs were reported as 70.24%, 100%. The negative predictive value of USG was reported as 96.17% along with 94.59% positive predictive value. In the contrast, conventional radiography gave a better positive predictive value (100%) than USG In our study we found better results of ultrasonography in terms of sensitivity and negative predictive value. Conclusion: In conclusion, our study depicts that ultrasonography is an economical, useful diagnostic tool for examining the bony fractures of facial trauma with a better sensitivity rate when compared to conventional radiographs.
