“…All participants underwent nasal ultrasongraphy using a small linear 7.5 MHz transducer (Aloka 3500, Tokyo, Japan) which was placed parallel to the nasal bone without a stand-off pad 3 by a radiologist who has 10 years clinical experience and is an expert in soft-tissue and musculoskeletal imaging. The radiologist was blind to the CT findings.…”

“…Imaging procedures in midface traumas are also needed for forensic reasons. 3 Although a routine radiographic examination is the main diagnostic tool for traumas to the nose, it is not very accurate and it is difficult to determine which side is fractured on conventional radiographs. 4,5 CT has been considered as a gold standard and it is the procedure of choice for diagnosing complex facial fractures, especially mid-facial fractures.…”

“…Ultrasonography is a non-invasive, inexpensive technique that has been shown to reveal fractures of different areas of the face, such as the nasal bone, 2,3,6 orbital floor, 7,11 anterior wall of the frontal sinus 6 and zygomatic fractures. 8,12 Previous studies have evaluated the use of ultrasonography in detecting nasal bone fractures in cases where a fracture had already been diagnosed.…”

“…8,12 Previous studies have evaluated the use of ultrasonography in detecting nasal bone fractures in cases where a fracture had already been diagnosed. 2,3 However, the sensitivity and specificity of ultrasonography has not been tested in the diagnosis of nasal bone fractures. The aim of this study was to evaluate the diagnostic value of ultrasonography in detecting nasal bone fractures compared with CT as the reference method in a single-blind study.…”

Objectives: The aim of this study is to compare ultrasonography with CT in the diagnosis of nasal bone fractures. Methods: 40 patients (9 female and 31 male) with mid-facial fractures, which were suspected nasal bone fractures, were included. All of the patients had mid-facial CT images. Ultrasonography with a 7.5 MHz transducer (Aloka 3500, Tokyo, Japan) was used to evaluate the nasal bone fractures. All of the sonograms were compared with CT findings for sensitivity, specificity and predictive values. A x 2 test was applied to the data to assess statistical significance. Results: CT diagnosed nasal bone fractures in 24 of the 40 patients (9 unilateral fractures and 15 bilateral fractures) while ultrasonography diagnosed the fractured bones in 23 patients (9 unilateral fractures and 14 bilateral fractures). Ultrasonography missed one fractured bone in a bilateral fractured case and a unilateral fracture was also missed (two false-negative results). The sensitivity and specificity of ultrasonography in assessing nasal bone fracture in comparison with CT were 94.9% and 100%, respectively. The positive predictive value (PPV) and the negative predictive value (NPV) of ultrasonographic evaluation of the nasal bone fractures were 100% and 95.3%, respectively. The x 2 test did not show any significant difference between CT and ultrasonography in diagnosis of nasal bone fractures (P 5 0.819). Conclusion: Ultrasonography can be used as a first line of diagnostic imaging for evaluating nasal bone fractures, especially in children and pregnant women.

Yirmi yaşında erkek, acil servise darp nedeniyle getirildi. Hastanın yapılan yatak başı acil ultrasonografi sinde nazal kemikteki kırık hattı irregüler hiperekojen ir hat olarak gösterildi. Nazal kemik kırıklarının acil serviste yatak başı ultrasonografi k olarak belirlenmesi, basit, ucuz, radyasyona maruz kalmadan yapılan bir yöntemdir. (JAEM 2010; 9: 148-9) Key words: Nazal kırık, ultrasonografi , acil tıp ÖzetA 20-year-old man presented to the emergency department with nasal fracture after a personal assault. The nasal bone appeared as a hyperecogenic structure on ultrasonographic examination and the irregularity and displacement of the bone was recognized. The evaluation of nasal bone fractures by ultrasonography is a proposed method involving no radiation exposure, rapid topographic evaluation and bedside application.
