Due to its versatile applicability, many reconstructive surgeons use the radial forearm flap (RFF) as the first choice for soft tissue replacement. Donor site limitations of the flap arise with an insufficient blood supply along the ulnar artery. This study presents a simple and safe method for RFF preconditioning by recruitment of the deep palmar arch via the ulnar artery. Fourteen patients scheduled for RFF surgery between 2013 and 2018 showed an insufficient vascular supply according to the Allen test, which was confirmed by digital subtraction angiography (DSA). These 14 patients underwent temporary ligature of one or both radial arteries with elastic vessel loops under local anaesthesia and continuous pulse oximetry. A control DSA was performed about 24 hours later in 10 of the 14 patients. Recruitment of the blood supply along the enlarged ulnar artery or reanimated collaterals was confirmed in all 10 patients. No local complications such as ischemia of the hand were seen. All flaps could be harvested regularly and were used for different reconstructive purposes. This simple technique may help to overcome vascular limitations of the RFF via the rapid, efficient, and reliable recruitment of the biological vascular reserve. Within the limits of a case series, this procedure appears practicable and safe. [ABSTRACT FROM AUTHOR]

Abstract: Retrobulbar haemorrhage is a sight-threatening condition that can occur after orbital trauma. The aim of this study was to evaluate the frequency and outcome of orbital haemorrhages following orbital fractures in geriatric patients receiving anticoagulants. All patients aged 65 years or more suffering from orbital fractures between 2008 and 2009 were included in this study. The mechanism of trauma, underlying diseases, and medication were recorded. In case of a retrobulbar haemorrhage, surgical exploration, the elapsed time between the onset of haemorrhage symptoms and surgical treatment, and the outcome regarding visual acuity were documented. Sixty-eight orbital fractures occurred (31 males, 37 females, age 65–95 years) resulting in six (3%) orbital haemorrhages. Four cases were associated with initial orbital bleeding, two other patients developed orbital haemorrhage as a complication after surgical reconstruction. Anticoagulant therapy, but not aspirin, was associated with a significantly increased risk of retrobulbar haematoma (p =0.02). Two patients permanently lost vision, two partial recoveries and two total recoveries were observed. Patients receiving anticoagulants have a higher risk of orbital haemorrhage after orbital fracture and should be monitored closely. Any evidence of visual impairment should lead to further investigation and prompt treatment. [Copyright &y& Elsevier]

Abstract: Bisphosphonates (BPs) are widely used as bone-stabilizers, but side effects of BP therapy include bisphosphonate-related osteonecrosis of the jaw (BRONJ), which is resistant to therapy. The aim of this study was to evaluate the outcome of maxillary BRONJ involving sinusitis maxillaris. 21 patients presenting with maxillary BRONJ, from 2005 to 2008, were included in the study. In 18 cases BP had been administered for carcinoma and in 3 cases for osteoporosis, with an average exposure time of 47.4 months. 12 patients spontaneously developed BRONJ. The 10 patients diagnosed with stage III BRONJ presented with concomitant sinusitis maxillaris. Despite treatment, there were six recurrences of BRONJ, four of them with additional sinusitis maxillaris. Whether BRONJ occurred spontaneously or after extraction there was no difference in the outcome. Patients with advanced maxillary BRONJ often suffer from sinusitis maxillaris, both of which are frequently resistant to therapy. [Copyright &y& Elsevier]
