Orbital blowout fractures are relatively rare in patients under 18 years of age, but may lead to serious complications. We conducted this retrospective study to evaluate diplopia, clinical characteristics, and postoperative results in cases of orbital blowout fractures in the pediatric population. Eighty-three patients, all less than 18 years old, with orbital blowout fractures, were divided in...

BACKGROUND AND PURPOSE Carotid blowout is a serious late complication of prior treatment of advanced head and neck cancer. We evaluate the efficacy of CTA in the diagnosis of impending carotid blowout syndrome in patients with head and neck cancer, and its capability to predict clinical outcome. MATERIALS AND METHODS The clinical data of 29 patients with impending carotid blowout who underwen...

Kick occurrence is a possible event during a drilling process. It is required to be handled immediately using a well control method to avoid blowout, financial losses and damages to the drilling crew. Several methods including driller, wait and weight, and concurrent are applicable in the drilling industry to control a well during a kick incident. In this study, typical well control methods wer...

PURPOSE To review our institution's recent experience with patients with carotid blowout syndrome who were referred for emergency diagnostic angiography and endovascular therapy. METHODS Eighteen consecutive patients who had had surgery for cancer of the head and neck and in whom carotid blowout syndrome had occurred were referred to our service in accordance with a standardized protocol. R...

BACKGROUND Carotid blowout syndrome with pseudoaneurysm, a rapidly progressive pathology, may present emergently with massive oral hemorrhage. Use of an endograft prosthesis offers a treatment strategy with salvation of the carotid artery. CASE HISTORY A 55 year old man with advanced squamous cell carcinoma of the head and neck presented with recurrent transoral hemorrhage, requiring endovasc...

OBJECTIVE To ask experts in the field to evaluate a surgeon's experience with a retroseptal transconjunctival approach for the repair of the orbital floor damaged by blowout fracture that the surgeon encountered in 12 East-Asian patients. METHODS Patients were identified from a database, and a retrospective case note review was conducted. A total of 12 conjunctival procedures were conducted f...

Recent works have demonstrated that a blowout bifurcation can lead to symmetry breaking in chaotic systems with a simple kind of symmetry. That is, as a system parameter changes, when a chaotic attractor lying in some invariant subspace becomes unstable with respect to perturbations transverse to the invariant subspace, a symmetry-broken attractor can be born. As the parameter varies further, a...

Abstract We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series solar blowout-eruption flares with successively increasing intensities (M2.0, M2.6, and X1.0). The originated NOAA Active Region 12017 during 2014 March 28–29 within an interval ≈24 hr. Coronal magnetic field modeling based on nonlinear force-free extrapolation helps to id...
