OBJECTIVES/HYPOTHESIS The objective was to determine whether low-frequency repetitive transcranial magnetic stimulation (rTMS) improves tinnitus by decreasing neural activity in auditory processing regions of the temporal cortex and the utility of positron emission tomography (PET) for targeting treatment. STUDY DESIGN Randomized, sham-controlled(More)
PURPOSE OF REVIEW Tinnitus is a debilitating condition that affects a broad range of patients. Despite thorough and extensive research, the cause of tinnitus has yet to be determined. Also, there has never been a single intervention identified that can consistently eliminate the symptoms of tinnitus. However, despite our inability to 'cure' tinnitus, there(More)
OBJECTIVE To determine factors that predict hearing results using a standard prosthesis system. STUDY DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENTS All patients undergoing ossiculoplasty with the Dornhoffer HAPEX partial and total ossicular replacement prostheses (PORP and TORP) from February 1995 to May 1999 who had(More)
With the invention of magnetic resonance imaging (MRI) and the auditory evoked brain stem responses (AEBR), it has become possible to diagnose acoustic tumours while they are still small. As a result, it has become obvious that the clinical presentation of smaller lesions can be some-what different from what is considered typical of an acoustic neuroma.(More)
OBJECTIVES/HYPOTHESIS Low-frequency repetitive transcranial magnetic stimulation (rTMS) has been shown to alleviate tinnitus perception, presumably by inhibiting cortical activity associated with tinnitus. We conducted a pilot study to assess effectiveness of neuronavigated rTMS and its effects on attentional deficits and cortical asymmetry in four patients(More)
BACKGROUND Tinnitus affects 10% of the population, its pathophysiology remains incompletely understood, and treatment is elusive. Functional imaging has demonstrated a relationship between the intensity of tinnitus and the degree of reorganization in the auditory cortex. Experimental studies have further shown that tinnitus is associated with synchronized(More)
OBJECTIVE To correlate patient response and recurrence rate after canalith repositioning to clinical presentation and cause of BPPV. STUDY DESIGN This was a retrospective chart review. SETTING This study was performed at a tertiary referral center. PATIENTS The study included patients with a diagnosis of benign paroxysmal positional vertigo based on(More)
Cigarette smokers and substance users discount the value of delayed outcomes more steeply than non-users. Higher discounting rates are associated with relapse and poorer treatment outcomes. The left dorsolateral prefontal cortex (DLPFC) exerts an inhibitory influence on impulsive or seductive choices. Greater activity in the prefrontal cortex is associated(More)
OBJECTIVE To explore the etiology of pediatric unilateral severe-to-profound sensorineural hearing loss (USPSNHL) and the risk of hearing loss in the contralateral ear. METHODS Pediatric patients with USPSNHL referred to a tertiary children's hospital for unilateral bone-anchored hearing aid implantation were identified for study. Clinical charts,(More)
Labyrinthine fistulas occur in approximately 5% of cholesteatoma cases, but the management of this difficult problem remains controversial. This study assessed the preoperative presentation and outcome in 37 patients operated on for cholestatoma complicated by labyrinthine fistula. Therapy involved removing the matrix from each fistula and reconstructing(More)
