Skull-base osteomyelitis (SBO) occurs secondary to invasive bacterial and fungal infection. Distinguishing between fungal and bacterial aetiologies of SBO has significant therapeutic implications. An 18-year (1990-2007) retrospective review of patients with SBO presenting to Westmead Hospital was performed. Epidemiological, clinical, laboratory and(More)
OBJECTIVES/HYPOTHESIS To characterize revision cochlear implant surgery and quantify rates of revision and device failure. STUDY DESIGN Retrospective review of 235 cases of revision cochlear implant surgery performed at the Sydney Cochlear Implant Center over a period of 30 years, between January 1982 and June 2011. METHODS Patient demographics and(More)
OBJECTIVE To quantify the postoperative quality of life in patients following surgical treatment for vestibular schwannoma. STUDY DESIGN Patient self-assessment using the short form 36 (SF36) multidimensional quality of life health questionnaire. Sex- and age-matched normalized scores were calculated using a standardized process and accepted normative(More)
The reversible hearing loss in the nonoperated ear noted by patients after ear surgery remains unexplained. This study proposes that this hearing loss is caused by drill noise conducted to the nonoperated ear by vibrations of the intact skull. This noise exposure results in dysfunction of the outer hair cells, which may produce a temporary hearing loss.(More)
OBJECTIVE We report a case of Sweet's disease associated with rapid, profound loss of hearing, against a background of progressive, bilateral, sensorineural hearing loss. RESULTS The clinical features were indistinguishable from those of immune-mediated inner ear disease. Establishment of a definitive diagnosis was a challenge due to the absence of a(More)
The results of 50 cases of vestibular schwannoma surgery with hearing preservation performed by the retrosigmoid approach at Addenbrooke's Hospital, Cambridge, during a 10-year period are presented. The hearing-preservation rate, using audiometric criteria set by others as "serviceable hearing" (Wade PJ, House W. Otolaryngol Head Neck Surg 1984;92:1184-93;(More)
A consecutive series of 51 patients (34 females and 17 males) with posterior semicircular canal benign positional paroxysmal vertigo (BPPV) were treated with the modified Epley particle positioning manoeuvre (PRM). Follow-up data were available on all 51 patients. After one manoeuvre, 42 patients had a negative Dix-Hallpike test, and after a second(More)
OBJECTIVE AND IMPORTANCE Traditionally, magnetic resonance imaging (MRI) was contraindicated for patients with cochlear implants (CIs), due to concern about device displacement, overheating of the device or tissues, or direct damage to the device electrode. In addition, image artifact from the device magnet gave poor imaging information in the cranial and(More)
OBJECTIVE This study aimed to quantify the atypical presentations of patients with vestibular schwannoma by applying the audiologic criteria for the treatment of patients to the Cambridge series of such tumors to show that clinical acumen is necessary for the effective screening of these tumors. STUDY DESIGN This study was a retrospective case review of(More)
