BACKGROUND Orbital fracture usually occurs as a result of blunt orbital and facial trauma and may involve ocular injuries. International studies on orbital floor fracture show several differences in epidemiology, diagnostic criteria, surgical treatment modalities, and complication rates; therefore, any comparison should be made with caution. Here we describe an unusual case involving a 19-year-...

INTRODUCTION We report a case of subcutaneous emphysema and periorbital oedema following a dental procedure. CASE PRESENTATION A 55-year-old female who attended Accident and Emergency department with subcutaneous emphysema of the neck and periorbital oedema several hours after having undergone root canal treatment. She was admitted for prophylactic intravenous antibiotics and was discharged t...

AIM Evaluation of the diagnostic contribution of color duplex sonography of the temporal, carotid and vertebral arteries and doppler sonography of the periorbital arteries in patients with and without giant cell arteries (GCA) particularly to distinguish between arteritic and nonarteritic neuro-ophthalmological vascular complications (NOC). METHODS In a prospective study ultrasonographic find...

Objective. To evaluate the occurrence of two periorbital complications of surgery for Chronic Suppurative Otitis Media (CSOM) and discuss the potential pathophysiologic mechanisms. Materials and Methods. This is a retrospective review of the CSOM surgeries performed between Oct, 2005, and Jan, 2011, in our hospital. The early postoperative conditions of the patients were scrutinized to identify...

Infrared thermal imaging of the inner canthi of the periorbital regions of the face can potentially serve as an input signal modality for an alternative access system for individuals with conditions that preclude speech or voluntary movement, such as total locked-in syndrome. However, it is unknown if the temperature of these regions is affected by the human startle response, as changes in the ...

In this study, we investigated human mesenchymal stem cell (hMSC) interactions with uniform hydrogels and hydrogels with lamellar or hexagonal surface wrinkles to elucidate our ability to control hMSC morphology and differentiation. Wrinkled hydrogels were prepared from photocurable poly(2-hydroxyethyl methacrylate) (PHEMA) precursor solutions containing ethylene glycol dimethacrylate as a cros...

Wrinkles in graphene with desirable morphology have practical significance for electronic applications. Here we carry out a systematic molecular dynamics study of the wrinkling instability of graphene on substrate-supported nanoparticles (NPs). At a large NP dispersion distance, a monolayer graphene adheres to the substrate and bulges out locally to wrap around individual NPs, forming isolated ...

Introduction: Skin photoaging can be treated with ablative therapies that may cause immunological changes to the skin. Objective: To evaluate the results of chemabrasion in the treatment of perioral wrinkles and the change in number of Langerhans cells. Material e methods: Application of 35% trichloroacetic acid followed by manual dermabrasion using waterproof sandpaper in 12 female patients wi...
