“…6,8 It has been reported that high-frequency probes reveal subtleties of bone structure and high-resolution scanners reveal minor bone displacements up to 0.1 mm, although operator expertise should also be taken into account. 8 A 7.5 MHz linear probe was used in the present study and the results were consistent with the results of studies carried out by Mohammadi 17 and Thiede 2 in which a 10 MHz linear probe was used. Furthermore, our results are consistent with the results of Danter,18 in which a 20 MHz probe was used to evaluate nasal bone fractures.…”

“…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. [6][7][8] However, CT techniques are expensive, are not readily available and provide a high patient exposure dose. Owing to the proximity of the eyes and the thyroid gland, there is an increased risk for cataract and thyroid carcinoma from X-ray exposure.…”

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.

“…It is contraindicated in pregnant women and in patients with cervical spine injuries. It has traditionally been used in the diagnosis of orbital and ocular lesions, but its role in maxillofacial trauma was not well recognized till the 20th century [36][37][38][39]. McCann et al used ultrasound with 85 % accuracy in diagnosing fractures of the zygomatico-orbital complex (ZMC).…”

Maxillofacial surgery, like any other surgical specialty is greatly dependent on the discipline of radiology. This poses a greater challenge because of the complex anatomy of this region. Various investigation modalities have been applied in diagnosing various diseases which are found in the maxillofacial region, including IOPA, PET, USG, CT, MRI and panoramic radiographs. Of these, USG can easily diagnose non invasive and soft tissue diseases. It is very useful in diagnosing the diseases which are not usually evident on a conventional radiograph. However; many of the dentists are not aware of the benefits of USG in diagnosis of oral diseases. In this article, the use of ultrasound in diagnosing the various pathologies of maxillofacial region is elaborated.

“…Conventional radiography remains the standard imaging procedure, but water's view targeting the lateral nasal walls is prone to misinterpretation [5,6]. Computed tomography (CT) is considered a gold standard for diagnosing complex facial fractures, especially mid-facial fractures [7][8][9]. However, CT is expensive, not readily available, and exposes the patient to high doses of penetrating radiation [4].…”

The purpose of this study was to evaluate and compare the diagnostic efficacy of ultrasonography (US) with radiography and multi-detector computed tomography (CT) for the detection of nasal bone fractures. Forty-one patients with a nasal bone fracture who underwent prospective US examinations were included. Plain radiographs and CT images were obtained on the day of trauma. For US examinations, radiologist used a linear array transducer (L17-5 MHz) in 24 patients and hockey-stick probe (L15-7 MHz) in 17. The bony component of the nose was divided into three parts (right and left lateral nasal walls, and midline of nasal bone). Fracture detection by three modalities was subjected to analysis. Furthermore, findings made by each modality were compared with intraoperative findings. Nasal bone fractures were located in the right lateral wall (n = 28), midline of nasal bone (n = 31), or left lateral wall (n = 31). For right and left lateral nasal walls, CT had greater sensitivity and specificity than US or radiography, and better agreed with intraoperative findings. However, for midline fractures of nasal bone, US had higher specificity, positive predictive value, and negative predictive value than CT. Although two US evaluations showed good agreements at all three sites, US findings obtained by the hockey-stick probe showed closer agreement with intraoperative findings for both lateral nasal wall and midline of nasal bone. Although CT showed higher sensitivity and specificity than US or radiography, US found to be helpful for evaluating the midline of nasal bone. Furthermore, for US examinations of the nasal bone, a smaller probe and higher frequency may be required.
