Abstract

Purpose: To evaluate the role and significance of ultrasonography in the general complex of methods of radiation diagnosis of bone fractures of the maxillofacial region.

Material and methods: Ultrasound examination was carried out on 104 patients at the age of 6–59 with trauma of the maxillofacial region. All patients were examined with sonography (SLE-501 device with linear frequency controller at 7.5 MHz, Lithuania), radiography and multislice computed tomography (Somation Emotion 6 device, Siemens, Germany).

Results: Fractures of the maxillofacial bones confirmed in 96 patients, including 36 isolated, 60 multiple and associated injuries of bones of the maxillofacial region. All injuries were identified by CT with 3D reconstruction, thus the method was adopted as verifying during analysis and comparison of results produced by other methods of visualization.

The ultrasonography findings revealed the following: interruption of the cortical layer with or without displacement of bone fragments, bone contour deformation. In 11 out of 13 cases of mandibular fractures with negative sonographic signs were detected by sonography with functional tests with the mouth opening. In comparison with X-ray, ultrasonography was more sensitive in detecting fractures (94.0 % to 81.5 %), especially in fractures of the front wall of the maxillary sinus, articular and coronoid process of the mandible.

Ultrasonographic examination was carried out with 57 patients after closed and open reposition. The unsatisfactory condition of bone fragments, which need re-repositioning, were detected in 25. In 11 patients sonography was used intraoperatively to control the repositioning of the bone fragments, thus making it possible to achieve satisfactory results after operations.

Conclusion: Ultrasonography has proved to be a valuable tool in detecting fractures in the facial bones in addition to X-ray examination. Particular value of sonography is a control for repositioning bone fragments.

Key words: trauma, maxillofacial region, sonography
