There is considerable evidence from studies on cats and monkeys that several cortical areas such as area 2v at the tip of the intraparietal sulcus, area 3av in the sulcus centralis, the parietoinsular vestibular cortex adjacent to the posterior insula (PIVC) and area 7 in the inferior parietal lobule are involved in the processing of vestibular information.(More)
OBJECTIVE The aim of this study was to assess any dysfunction of the sacculus in patients with unilateral Meniere's disease by monitoring the vestibular evoked myogenic potentials (VEMPs) evoked by high level clicks on the Stemomastoid muscles (SCMs). STUDY DESIGN The study was a retrospective analysis. SETTING The study was performed in the E.N.T.(More)
OBJECTIVES Juvenile nasopharyngeal angiofibroma often recurs if the tumor is large. This report is a long-term follow-up of these cases. It establishes the prognostic values of tumor extensions, analyzes the anatomic factors involved in recurrences, describes the spontaneous evolution of remnants based on a radiographic follow-up, and evaluates the(More)
OBJECTIVES To demonstrate mucosal biofilms in human tissue by direct visualization of bacteria and glycocalyx using confocal laser scanning microscopy with double fluorescent staining on tonsils and to compare the findings with the results of scanning electron microscopy analysis. DESIGN Prospective study. SETTING Tertiary university-based referral(More)
Surgery for jugular paraganglioma (PGL) tumors often results in the acquisition of neurological deficits where none had been present previously. This has a significant impact on the quality of life. Radiotherapy is a recognized alternative therapy. The aim of this study was to compare the results of radiotherapy and surgery for the management of jugular PGL(More)
 Presentation. Jugulare foramen tumors (JFT) remain a difficult challenge especially in the forms extending extradurally and invading the petrous bone. In the standard technique, facial nerve function is placed at risks because of its transposition. We report on 31 extradural (N=11) or intra-extra dural (N=20) JFT resected surgically using the juxtacondylar(More)
OBJECT The object of this study was to evaluate the natural history, pattern, and occurrence of tumor growth and its consequences for treatment of small-sized vestibular schwannomas (VSs). METHODS From 1990 to 2005, 386 patients underwent conservative management for VS because of the following: age > 60 years, poor health/medical risks, risk of(More)
OBJECTIVE To investigate whether delay in treatment has any influence on the audiometric outcome at Day 30 in idiopathic sudden sensorineural hearing loss. STUDY DESIGN Prospective study. SETTING Otorhinolaryngologic emergency center in Paris, France. PATIENTS Three hundred forty-seven consecutive cases of sudden sensorineural hearing loss were(More)
The purpose of this report is to present indications and risks of endoscopic transsphenoidal approach to treat petrous apex cholesteatoma. This is a retrospective analysis of two cases of petrous apex cholesteatoma presenting with double vision who underwent an endoscopic transsphenoidal approach at Lariboisiere Hospital, Paris, France. Control of the(More)
The present study aimed at determining whether vestibular inputs contribute to the perception of the direction of self-motion. This question was approached by investigating the effects of binaural bipolar galvanic vestibular stimulation (GVS) on visually induced self-motion (i.e., vection) in healthy subjects. Stationary seated subjects were submitted to(More)
