We conducted a retrospective study of 51 cases of spontaneous transtemporal cerebrospinal fluid (CSF) leakage in 48 adults who had presented to our tertiary care academic referral center between July 1, 1988, and June 30, 2002. All patients had undergone high-resolution temporal bone computed tomography, and 26 patients had undergone magnetic resonance imaging. All patients were treated with a ...

Spontaneous intracranial hypotension (SIH) is characterized by severe postural headache and low cerebrospinal fluid (CSF) pressure. Radionuclide cisternography (RC) is of some value in diagnosing CSF leakage causing SIH. However, the sensitivity of RC is too low to demonstrate the site of leakage. In these cases, the early appearance of the radioactivity in the urinary bladder has also been use...

To the Editor:—We read with interest the article of Conzen et al. demonstrating a reduction of cardiac troponin I release after coronary artery bypass grafting on the beating heart when sevoflurane was compared to propofol. Most previous studies identified peak postoperative troponin I as the major endpoint. It is not clear from the article of Conzen et al. which was the peak postoperative trop...

BACKGROUND The prosthetic dura is an essential element in the protection of the cranial parenchyma and prevention of cerebrospinal fluid leakage. Although prosthetic dura are widely used in neurosurgery, they occasionally provoke infection, which can be a major concern after neurosurgical treatment. However, removal of the prosthetic dura carries a risk of brain parenchyma injury and cerebrospi...

This study analyzed the factors that caused intracranial infection after endoscopic resection of the pituitary tumors by transnasal-sphenoidal approach. A retrospective analysis was performed for 326 patients with resection of pituitary tumor, and multiple Logistic regression analysis was conduced for the relevant factors. Results showed that a total of 32 patients exhibited postoperative infec...

AIM This study aims to evaluate the hemilaminectomy approach and in situ restoration of vertebral laminae in microsurgery for thoracic intraspinal tumors. MATERIAL AND METHODS Sixteen patients with thoracic intraspinal tumors, consisting of 6 males and 10 females with a mean age of 47.5±16.4 years ranging from 21 to 71 years, underwent surgical treatment with hemilaminectomy approach and in s...

OBJECTIVE AND IMPORTANCE Intrasphenoidal encephalocele is a rare clinical entity that is often complicated by rhinorrhea, recurrent meningitis, and headache, but in no case has the association of rhinorrhea with subdural hematomas been described. A surgical procedure to stop persistent cerebrospinal fluid leakage is reported. CLINICAL PRESENTATION A 59-year-old man sought care for intractable...

A retrospective review was performed of patients treated for middle ear cholesteatoma with bone defects of the skull base via a combined transmastoid/middle fossa approach at the University of Tsukuba Hospital from 2006 through 2011 to determine the safety and effectiveness of a combined transmastoid/middle fossa approach for the treatment of cholesteatoma involving the middle cranial fossa. Th...
