A Comparative Study on the Diagnostic Utility of Ultrasonography with CT Scan/Conventional Radiography in Detection of Fractures of The Facial Skeleton

Abstract
Abstract: The importance of imaging in maxillofacial trauma cannot be underrated. Traditionally CT scans have been considered the gold standard even though they have disadvantages like associated radiation hazards, high cost factor, unavailability in rural health care set up, etc. This has compelled ongoing research to seek imaging modalities that circumvent these aspects. Ultrasonography is a quick, inexpensive, non-ionizing radiographic modality which offers several advantages over conventional use of CT or plain film radiographs. We aimed to explore the versatility and efficacy of the use of Ultrasonography and compare it to CT/conventional radiographic modalities in detection of fractures of the midface and mandible. 40 patients with maxillofacial trauma underwent radiographic assessment using ultrasound and CT/conventional radiographs. We observed a high correlation between Ultrasonography and CT scan in the detection of maxillofacial fractures. Sensitivity and specificity was 100% with a high PPV. Apart from a few limitations, such as difficulty in interpretation of a film without a report or clinical correlation, and examiner variability, the advantages associated with its use probably outweigh the shortcomings. Further research in the technical aspects and training in the application of this method to trauma is likely to witness USG becoming the modality of choice as an initial screening tool for detection of uncomplicated fractures.
