“…Plain X-ray does not work for viewing IOWFB because it is hard to visualize wood with this modality. [10,11] USG has a very limited role as it requires expertise and is not reliable for imaging the orbital apex. [10,12] Moreover, it can image the proximity of the orbital cavity in the absence of orbital imaging.…”

Background and aim: Entrapment of foreign-bodies is a common phenomenon in traumatic events occurring in the maxillofacial region. The purpose of this study was to evaluate the efficiency of panoramic, CT, Cone-beam CT, MRI and ultrasonography in detecting different foreign-bodies in the maxillofacial region. Methods: Four different materials were used as foreign-body including metal, glass, rubber and wood. These particles were prepared in four different sizes from 2*2*2 mm to 5*5*5 millimeters. The foreign-bodies were then implanted into a sheep's head in the infraorbital part of maxilla and mandibular buccal region. The panoramic, CT, Cone-beam CT, MRI and ultrasonography were obtained from the model and the images were blindly observed and analyzed by two radiologists. A four-point scale was used to interpret the visibility of found foreign-bodies. Results: CT had the best efficiency in detecting different foreign-bodies. Cone-Beam CT was the next useful technique. The ability of differentiating the foreign-bodies from the adjacent structures were poor in MRI and ultrasonography. As expected, the panoramic was only efficient in detecting metallic bodies. Conclusion: CT-scan can be introduced as the best imaging modality in detecting different foreign-bodies especially non-metallic ones. CBCT is also acceptable for metal, glass and rubber particles.

“…3 The general consensus throughout the literature is that the most effective means of evaluating the presence of soft tissue foreign bodies is through the use of CT scanning. 4,7,8 Moreover, the use of ultrasound biomicroscopy has also been found by several investigators to be significantly better in identifying intraocular foreign bodies compared with X-ray. [9][10][11] In fact, ultrasound has even been reported to detect intraocular foreign bodies in several instances when CT scanning failed to do so.…”

Aims To evaluate the role and efficacy of portable X-ray in reliably identifying retained suture needles in ophthalmologic surgical cases. Methods Ophthalmologic 10À0 nylon suture needles were placed into 10 of 20 porcine eyes positioned within the orbit of a human skull. Portable, plain film radiographs were taken of all eyes with a C-arm fluoroscopy machine. The films were reviewed by six ophthalmologists and six radiologists who were blinded to the presence or absence of needles, as well as the number of needles used in the protocol. The sensitivity and specificity of identifying retained suture needles by plain film radiographs were then analysed based on the results of the physicians' interpretations of the films. Results The overall sensitivity and specificity for physicians reviewing radiographs with suspected intraoperative suture needles were 54 and 77%, respectively. When looking separately at radiologists reviewing the films, the sensitivity was 57% and the specificity was 87%. Ophthalmologists reviewing the films identified retained needles less reliably with a sensitivity of 51% and a specificity of 67%. Conclusions Significant controversy exists regarding the reliability and utility of plain film radiography in identifying intraocular foreign bodies. This study demonstrates that the use of plain film radiographs to rule-out the presence of an intraocular surgical needle is neither a sensitive nor specific imaging modality.
