Tomoki Nishiyama
BACKGROUND: To know the objective methods of the effects of the brachial plexus block, we studied the changes in percutaneous oxygen pressure (tcPO₂) with the hypothesis that tcPO₂ increases significantly on the blocked arm in comparison with the non-blocked arm, a phenomenon which is connected with vasodilation following the brachial plexus block. METHODS: Fifteen patients scheduled for upper extremity surgery, aged 20 to 70 years, with ASA physical status I or II were included...

Tengfei Li, Xia Wu, Yuekang Zhang
A 56-year-old man was admitted to our hospital with intermittent right facial numbness for one year and walking instability for six months. Magnetic resonance imaging revealed an ovoid and well-demarcated intra-axial pontine lesion. Cyst fenestration and biopsy were carried out and the diagnosis of enterogenous cyst was made by MRI and pathologic findings. Preoperative symptoms resolved completely three months after surgery and no evidence of recurrence was found during 3 years of follow-up. Although total resection of enterogenous cysts is recommended, cyst fenestration may be useful if the cyst is adherent to vital neurovascular structures...

Ameloblastoma is a locally aggressive tumor derived from odontogenic epithelium. Although benign, its clinical behavior can often exhibit malignant characteristics. It is marked by slow and persistent growth with infiltration of adjacent tissues. Almost 70% occur in the mandible in patients older than 30 years. Recurrence of ameloblastoma from inadequate treatment is frequent. Because of its slow growth, recurrences can present decades after primary surgery. A primary ameloblastoma in an area outside the mandibular, maxillary, and infratemporal fossa regions has not been described in detail to date, with only 1 possible case mentioned in the literature...

The present study describes 3 patients of previous facial trauma who have subsequently been treated with functional endoscopic sinus surgery. The authors want pay attention on the possible correlation between facial trauma and sinusitis. Such fractures can be the cause of onset of paranasal sinusitis or of worsening of a previous sinusitis. The correlation between these 2 pathologies could be due to the fact that facial fractures concern the anatomic structures of paranasal sinuses. The damage to these structures during the facial trauma and tissue regeneration after injury or surgical treatment subverts the anatomy and function of the sinuses in a basically compromised situation...

Facial feminization surgery is a term to describe the surgical alteration of a masculine facial appearance to a more feminine appearance, which is most commonly performed for male-to-female transsexual individuals. To alter the midfacial relations, segmentalized osteotomies were performed in selected patients expanding on the established techniques for facial feminization surgery. All patients underwent a preoperative 3D computerized tomography scan and 3D photography before and after the surgery. The inclusion of the midface in surgery was determined based on the relative projection and angle of the zygomatic body compared with the supraorbital region (the supraorbital region was reduced in all patients)...

Juvenile angiofibroma is an uncommon, benign, locally aggressive vascular tumor. It is found almost exclusively in young men. Common presenting symptoms include nasal obstruction and epistaxis. More advanced tumors may present with facial swelling and visual or neurological disturbances. The evaluation of patients with juvenile angiofibroma relies on diagnostic imaging. Preoperative biopsy is not recommended. The mainstay of treatment is resection combined with preoperative embolization. Endoscopic surgery is the approach of choice in early stages, whereas, in advanced stages, open or endoscopic approaches are feasible in expert hands...

Nevus comedonicus (NC), a rare skin ailment with an aggregation of dilated follicular orifices filled with keratinous material, is difficult to treat. Several drugs have been assessed for the treatment of NC, but with limited success. Surgery requires much experience and the recurrence rate is high. Various types of laser have been tried, with promising outcomes. A 54-year-old male patient with bilateral facial NC was admitted on July 8, 2014. A coin-sized area was first treated successfully with ultrapulse CO2 laser...

The aim of this study was to investigate the association between RDW values and the prognosis of patients with Bell palsy in an effort to find a prognostic biomarker that predicts recovery from Bell palsy. We measured RDW and evaluated facial movement in 61 patients with Bell palsy aged 50 years and less. All patients were treated with a steroid plus an antiviral agent. Seven patients underwent surgery for facial nerve decompression. During the post-treatment period, patients with a Yanagihara grading score of 36 or more were regarded as having a satisfactory recovery...

BACKGROUND: The reported rate of isolated medial orbital wall fractures varies widely but has been found to be as high as 55% of all orbital fractures. Identifying and repairing medial orbital wall defects by using appropriate materials improves patient outcome considerably; however, most related research has focused on orbital floor defect management rather than medial orbital wall treatment, and no consensus on repairing medial orbital wall fractures exists. Furthermore, medial orbital wall fracture is a main cause of posttraumatic enophthalmos...

INTRODUCTION: Miescher's cheilitis is clinically characterized by persistent swelling of the lip(s). Its pathogenesis is still unknown. Histopathologically is characterized by sub-epithelial edema, increased number of dilated lymphatic vessels and an inflammatory infiltrate and/or non-caseating/non- necrotic granulomas. Even if the disorder must be controlled by medical therapy, surgery may be required to treat most severe cases. PRESENTATION OF THE CASE: We report a 30-year-old man who presented a persistent swelling of both lips since 8 years, previously treated with intralesional steroid and immunosuppressive therapy...

INTRODUCTION: Intramedullary cavernous angioma (ICA) is a rare lesion of the spinal cord, representing only 3% - 5% of central nervous system lesions. The coexistence of trigeminal neuralgia and refractory itch is very rarely encountered in clinical practice. To our knowledge, a report of an ICA with trigeminal neuralgia and local neuropathic itch has never been published to date. Thus, we present a very interesting case of a C2 ICA. CASE PRESENTATION: A 61-year-old female presented with right facial pain for three years, which was exacerbated by accompanying cervical pain and itch for one month...

This study validates a recently described pain scale, the Equine Utrecht University scale for facial assessment of pain (EQUUS-FAP), in horses with acute or postoperative pain originating from the head, including dental pain, ocular pain, or trauma to the skull. This cohort study of 23 horses with head-related pain and 23 normal, healthy controls revealed significant differences in EQUUS-FAP scores between control horses and horses with acute or postoperative pain (P <0.001). Moreover, pain scores after surgery decreased significantly over time (P <0...

Random skin flaps are commonly used in plastic and reconstructive surgery for patients suffering from severe or large scale wounds or in facial reconstruction. However, skin flaps are sometimes susceptible to partial or complete necrosis at the distal parts of the flaps due to insufficient blood perfusion in the defected area. In order to improve neovascularization in skin flaps, we developed an exogenous growth factor (GF) delivery platform comprised of coacervate-coated poly(lactic-co-glycolic acid) (PLGA) nanofibers...
