OBJECTIVE To evaluate the independent relationship of the Shaw scalpel on the development of facial nerve injury in patients undergoing superficial parotidectomy. METHODS A retrospective review of 77 cases between 1991 and 1996. Forty-eight percent of the surgical procedures were performed using the Shaw scalpel, and 52% were performed using a cold knife. To assess whether use of the Shaw sca...

Hypothalamic hamartoma (HH) is a benign indolent lesion despite the presentation of refractory epilepsy. Behavioral disturbances and endocrine problems are additional critical symptoms that arise along with HHs. Due to its nature of generating epileptiform discharge and spreading to cortical region, various management strategies have been proposed and combined. Surgical approaches with open cra...

Delayed neurologic deficit after a stab wound with a retained foreign body near the spinal canal is unusual, adequate radiological examination is fundamental in detecting retained foreign bodies, especially the CT scan, surgical extraction of the foreign body is the primary task and the surgical outcome is satisfactory. Here, we report a rare case of delayed myelopathy caused by spinal stenosis...

The medial basal hypothalamus was isolated from the remainder of the brain of the rat using a Halász knife. Ten to 14 days after the surgical procedure the concentration of thyrotropin-releasing hormone within the island of hypothalamic tissue was 76% lower than in tissue from sham-operated control rats. Thus, much of the thyrotropin-releasing hormone that is normally present in the medial basa...

Neovesical-urethral anastomotic stricture is a complication of orthotopic neobladder, with a reported incidence of 2.7% to 8.8%. Strictures of the neovesico-urethral anastomotic site can be treated with regular self-dilation, but high-grade strictures require a surgical procedure involving incision by electrocautery or cold knife. Here we describe a grade III neovesical-urethral anastomotic str...

A 77-year-old female presented with a rare cavernous sinus cavernous hemangioma with extension to the sella turcica, neuroradiologically mimicking nonfunctioning pituitary macroadenoma. The lesion was partially removed via transsphenoidal surgery, and the histological diagnosis was cavernous hemangioma. After stereotactic radiosurgery using a cyber knife, the lesion decreased in size. Stereotac...

BACKGROUND The goal of treatment in arteriovenous malformation (AVM) is total obliteration of the AVM, restoration of normal cerebral function, and preservation of life and neurological function. AIM To analyze the results of X-knife and surgery for AVM of the brain. The endpoints for success or failure were as follows: success was defined as angiographic obliteration and failure as residual ...

BACKGROUNDS With respect to the knife's design in colorectal endoscopic submucosal dissection (ESD), diameter, water jet function, and electric power are important because these relate to efficient dissection. In this study, we analyzed a novel, narrow ball tip-typed ESD knife with water jet function (Flush knife BT-S, diameter: 2.2 mm, length: 2000 mm, Fujifilm Co., Tokyo, Japan) compared to a...
