Percutaneous Ultrasound-Guided Intraorbital Foreign Body Removal

Intraorbital wooden foreign bodies: case series and literature review

Intraorbital wooden foreign bodies (IOWFBs) constitute a relatively rare ocular trauma, which occupy a special type of intraorbital foreign bodies (IOFBs). Data regarding IOWFBs must be obtained from case reports or small case series due to their rarity. Here, we reported 5 cases of IOWFBs and reviewed the related literatures, which could provide comprehensive information regarding the clinical manifestations, diagnosis, and surgical treatment of IOWFBs. Combined with the published literature, a total of 51 independent cases were counted after we added 5 cases. Among them, the number of male and female patients was 35 and 16 respectively; the mean age was 27.3±18.2 (range 1-66)y. Obviously, the disorder seemed to occur mainly in young and middle-aged people. Because of the diversity in the clinical manifestations and imaging characteristics of IOWFBs, misdiagnosis and missed diagnosis often occur during the initial visit. Delayed diagnosis may lead to a high risk of orbital infection caused by IOWFBs. Surgery is the treatment of choice for most patients; however, the missed diagnosis and residue of foreign bodies after previous surgery cannot be ignored. Therefore, an accurate diagnosis is governed by the detailed trauma history, careful ocular examination, close observation of clinical manifestations, correct imaging diagnosis [e.g., magnetic resonance imaging (MRI) or computerized tomography (CT)], and timely and completely elimination of IOWFBs.

Soft tissue foreign bodies: A training manual for sonographic diagnosis and guided removal

Sonography provides excellent detection, localization, and characterization of soft-tissue foreign bodies. Ultrasound guided foreign body removal is a safe and highly successful minimally invasive procedure that facilitates effective treatment and avoidance of complications in patients with soft tissue foreign bodies. Focused laboratory training is critical to successful implementation of a sonographic foreign body management practice.

Classification of orbitocranial wooden foreign body penetration injuries: what to do when they violate the intracranial space? A systematic review

INTRODUCTION

Orbitocranial wooden foreign body (OWF) penetrations are rare but challenging occurrences that may violate the intracranial space resulting in brain damage and hemorrhagic, as well as infectious, complications. Moreover, there is a specific subset of cases of OWF penetrations that are particularly challenging to treat. Although there are well-defined management guidelines for pure intraorbital localization, there is not yet a defined treatment protocol for foreign bodies reaching the intracranial space. However, their removal performed either directly or through craniotomy, is often easily attainable given the condition that all necessary precautions are accounted for.

EVIDENCE ACQUISITION

After having treated a 48-year-old man with a transorbital OWF penetration injury at our neurosurgical department, we systematically reviewed the last 15 years of literature to define and summarize the best management strategy. Multiple databases were searched for case reports and case series involving patients with intraorbital and transorbital OWF penetration injuries. For each study, we extracted data on age, sex, imaging modality, type of wood (processed vs. unprocessed), location of periorbital and intracranial entry site, treatment type ("pull and see" or "open and see"), antibiotic therapy, and complications.

EVIDENCE SYNTHESIS

We classified transorbital OWFs into two categories: transorbital with only cavernous sinus involvement and transorbital with more extensive intracranial involvement. We described what we believed was the most appropriate management conduct in each case.

CONCLUSIONS

Grounded on our experience and on the review of the literature, we suggest, based on the anatomical localization of the OWF, a classification system for OWFs which is coupled with a tailored treatment strategy for each case. These suggestions are made to provide surgeons with direction on the correct management of such rare but challenging occurrences.

Localization and Retrieval of an Eyelid Metallic Foreign Body With an Oscillating Magnet and High-Resolution Ultrasonography

A patient was found to have a metallic foreign body in the left anterior orbit on CT imaging, but the foreign body was not evident on clinical examination. On high-resolution ultrasonography, an object was identified in the left upper eyelid; however, the typical shadow with metallic foreign bodies was not seen. A high-power oscillating magnet was then applied to the eyelid, which revealed a subcutaneous metallic foreign body in the left upper eyelid. When used in conjunction, the high-resolution ultrasound and oscillating magnet successfully localized and facilitated retrieval of the metallic foreign body from the left upper eyelid.

Ultrasound-guided musculoskeletal procedures in children

Ultrasound is an excellent tool to evaluate many pediatric musculoskeletal conditions. It may be used for both diagnosis and for guidance for therapeutic procedures. With US, the radiologist can readily evaluate the contralateral side for comparison. No sedation is typically required and ionizing radiation is avoided. Real-time information is obtained with US and the portability of US allows for the performance of bedside interventions in children who cannot be transported or are clinically unstable. Limitations of US compared with MRI and CT include limited field of view, inability to evaluate the bone marrow and user dependence of image and exam quality. In this article, we discuss common US-guided musculoskeletal procedures in children, including hip aspiration, joint injection, soft-tissue biopsy and foreign body removal.

Self-embedding behavior: a new primary care challenge

OBJECTIVE

The goal of this study was to define self-embedding behavior (SEB), develop a clinical profile of adolescents who engage in SEB, and emphasize the importance of rapid, targeted, and effective identification and intervention.

METHODS

As part of a retrospective study with a database evaluating 600 patients percutaneously treated for soft-tissue foreign body removal, adolescents were identified with self-embedded soft-tissue foreign bodies. We describe patients' gender, age, and psychiatric diagnoses; SEB age of onset, frequency, and self-reported reasons; and the number, type, location of, and removal technique for objects.

RESULTS

Eleven patients (9 females) who engaged in SEB were identified. Ten of the 11 patients were members of a group home or psychiatric facility at the time they engaged in SEB. All patients had previous and multiple psychiatric diagnoses. SEB mean age-of-onset was 16 years, and mean number of SEB episodes per patient was 1.9. The most common self-reported purpose for SEB was suicidal ideation (6 of 8 [75%]) versus nonsuicidal ideation (2 of 8 [25%]), with 3 cases lacking this documentation. The mean number of objects embedded in a single episode was 2.4, usually composed of metal and embedded in the arm. Seventy-six foreign bodies were percutaneously removed (using ultrasound or fluoroscopic guidance), including metal, glass, wood, plastic, graphite, and crayon.

CONCLUSIONS

SEB is an extreme form of self-injury requiring aggressive and timely interdisciplinary assessment and treatment. An understanding of SEB allows medical professionals to pursue rapid, targeted, and effective intervention to interrupt the cycle of self-harm and institute appropriate long-term therapy.
