[Ultrasound imaging of nasal bone fractures with a 20-MHz ultrasound scanner].

High frequency B-scan ultrasonography is a proven method for the assessment of skin tumors and evaluation of the thickness of skin and cartilage layers. Only limited studies have used sonography to examine bony structures. Our goal was to evaluate the importance of ultrasonography in the diagnosis of nasal fractures. Patients with clinical and/or radiological evidence for such fractures were also examined with 20 MHz B-scan ultrasonography. Results of sonography demonstrated a significant correlation with the nasal fractures present, indicating that additional radiographic examinations are unnecessary in certain cases.
