Abstract Central giant cell granuloma (CGCG) is a relatively uncommon benign bony lesion accounting for approximately 7% of all non-neoplastic lesions of the jaw. The clinical behavior of CGCG can vary from a slow-growing, painless lesion to fast-growing and locally destructive. When such a lesion involves the mandible, this can be quite debilitating for the patient, inhibiting oral intake and requiring an extensive resection and bone graft reconstruction. The authors present a case of effectively decreasing the surgical morbidity associated with a large and rapidly growing CGCG of the mandible in a pediatric patient. Neoadjuvant immunotherapy with denosumab (human monoclonal antibody) facilitated treatment of the tumor without the need for a large resection which would have otherwise necessitated a vascularized bony mandibular reconstruction. Consideration of neoadjuvant medical management of CGCG as the primary treatment is advocated.

AbstractBackgroundShear wave elastography (SWE) shows promise in peripheral neuropathy evaluation but has potential limitations due to tissue size and heterogeneity. We tested SWE sensitivity to elasticity change and the effect of probe position in a median nerve cadaver model.MethodsTen specimens were used to measure median nerve elasticity under increasing loads using SWE and indentation. Measurements were compared using repeated‐measures analysis of variance.ResultsIndentation and SWE‐based longitudinal nerve elasticity increased with tensile loading (P< .01), showing a similar relationship. Acquisition in a transverse plane showed lower values compared with longitudinal measurements, mostly under higher loads (P= .03), as did postdissection elasticity (P= .02). Elasticity did not change when measured proximal to the carpal tunnel.ConclusionsLongitudinal SWE is sensitive to changes in median nerve elasticity. Measuring elasticity of peripheral nerves noninvasively could elucidate intra‐neural pathology related to compression neuropathies, and proof to be of added value as a diagnostic or prognostic tool.

Abstract Cranio-orbital trauma is an uncommon yet devastating injury, especially one in the setting of a high-energy gunshot wound. Such injuries were historically reported in the setting of military conflict, and are associated with vision-threatening complications, often resulting in anophthalmos. The authors report a case of a self-inflicted gunshot wound to the eye, which requires orbital enucleation with exposed frontal lobe dura. To address the exposed dura, the extraocular muscles were utilized from the enucleation procedure to cover the defect in the acute setting prior to final staged reconstruction.
