BACKGROUND Facial hypoesthesia is one of the most troublesome complaints in the management of facial bone fractures. However, there is a lack of literature on facial sensory recovery after facial trauma. The purpose of this study was to evaluate the facial sensory recovery period for facial bone fractures using Neurometer. METHODS Sixty-three patients who underwent open reduction of zygomatic...

The indications for surgical repair of the orbital blowout fracture are controversial. One reason may be case variation among fracture types. We therefore focused on linear-type blowout fractures in this study. The study included 22 consecutive patients with linear-type floor fractures. Demographics, clinical and computed tomographic (CT) findings, surgical timing, postoperative course, and out...

A blowout cardiac rupture is sudden and dramatic. The most appropriate surgical repair remains controversial. We report our experience with blowout rupture treated by sutureless technique. The two cases were males aged 58 and 79 years respectively. Echocardiography confirmed the diagnosis of cardiac rupture. Resuscitation was continued in the operating suite, and the myocardial tear and necroti...

BACKGROUND Enophthalmos may not appear immediately after trauma due to periorbital swelling in a blowout fracture, and preoperative measurements of enophthalmos cannot be used as a reliable guideline. It is important to predict the eventual final extent of enophthalmos in order to determine whether to perform surgery, and there have been several attempts to predict the degree of late enophthalm...

We consider attractors for certain types of random dynamical systems. These are skew-product systems whose base transformations preserve an ergodic invariant measure. We discuss definitions of invariant sets, attractors and invariant measures for deterministic and random dynamical systems. Under assumptions that include, for example, iterated function systems, but that exclude stochastic differ...

We show that loss of synchronization of two identical coupled chaotic class B lasers can occur via a blowout bifurcation. This occurs when a transverse Lyapunov exponent governing the stability of a synchronized subspace passes through zero. A system of two laterally coupled lasers with modulated parameters is investigated numerically in a region of chaotic behavior. A total of five invariant s...

We present the case of an 86-year-old woman who developed a blowout fracture after Descemet's stripping automated endothelial keratoplasty (DSAEK). Sixteen months after DSAEK, she suffered a blow to her left eye caused by a fall. Computed tomography confirmed the presence of a blowout fracture of the inferior wall of the left orbit with soft tissue prolapsing into the orbit. The patient complai...

Blowout bifurcations are investigated in a symmetrized extension of the replacement method of chaotic synchronization which consists of coupling chaotic systems via mutually shared variables. The coupled systems are partly linear with respect to variables that are not shared, and that form orthogonal invariant manifolds in the composite system. If the coupled systems are identical, marginal (pr...

BACKGROUND Actinomyces is a bacterial rod found in the normal oral flora. It can gain entry to the submucosa via trivial wounds and ultimately lead to slow growing lesions which may mimic cancerous lesions. METHODS AND RESULTS We present the case of an elderly, immunosuppressed woman who presented with a herald bleed from a tonsillar lesion. Despite initial operative arrest of the hemorrhage,...
