Two patients suffered from acute hearing loss of the contralateral side after acoustic tumor surgery were reported. The first patient was a 42-year-old-male. He had had a right progressive hearing loss over two years and CT scan revealed a mass of 20mm in diameter in the right cerebellopontine angle. The patient noticed the contralateral hearing loss on next morning after the total removal of t...

OBJECTIVE Noise-induced hearing loss (NIHL) is one of the most reported occupational diseases internationally. The occurrence of audiometric notches is emphasized in both American and European guidelines for the diagnosis of NIHL. The aim of this study was to describe the prevalence of notched audiograms among railway personnel with and without noise exposure to better assess the usefulness of ...

In order to investigate the physiological consequences of hydrops on auditory function an animal model has been developed in which endolymphatic hydrops is surgically induced and electrophysiological responses are monitored preceeding during and following hydrops induction. These studies have revealed that experimental hydrops systematically results in a fluctuant low frequency hearing loss ( b...

OBJECTIVES To compare the hearing of gold miners with and without tuberculosis (TB) to determine the effect of TB and its associated risk profile on hearing. METHODS Audiological and medical surveillance data of 2698 South African gold miners for 2001-2009 were analysed in a retrospective cohort design. Hearing thresholds for the air conduction frequencies (0.5, 1, 2, 3, 4, 6, 8 kHz) in both ...

Abstract Background Patients are frequently referred to ENT emergency services with sudden hearing loss. Differentiating sensorineural from conductive losses is paramount in establishing the urgency of review and when commence urgent steroid therapy. Tuning fork tests useful for this, but they not always readily available primary care or room. Aim To identify evaluate an alternative method Webe...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016218289 DESCRIPTION A man aged 56 years, with a history of moderate sensorineural hearing loss, presented with a fast progressing loss of hearing discrimination in his right ear. The audiogram confirmed the moderate sensorineural hearing loss with a speech discriminatio...

BACKGROUND AND OBJECTIVES The purpose of this study is to identify the effectiveness of intratympanic (IT) steroids when used as an initial therapy in sudden sensorineural hearing loss (SSNHL), and when it is used as a salvage therapy in a refractory SSNHL. SUBJECTS AND METHODS This retrospective study included 122 patients with SSNHL. First, patients were divided into three groups according ...

BACKGROUND There is an increased risk for labyrinthine injury for the resection of acoustic neuromas (AN) on the suboccipital, retrosigmoid approach. Prognostic factors should be analyzed for the postoperative hearing function. METHODS We examined 51 patients with ANs using preoperative intact hearing function. Audiological data were obtained by pure tone audiogram (PTA) and speech audiogram....

OBJECTIVE To evaluate the results of stereotactic radiosurgery treating vestibular schwannomas secondary to type 2 neurofibromatosis. METHODS A retrospective review of 122 type 2 neurofibromatosis vestibular schwannomas consecutively treated in 96 patients. Tumour control was assessed by recourse to surgical intervention, by serial radiological imaging, and by the calculation of relative grow...

BACKGROUND/AIM Idiopathic sudden sensorineural hearing loss (ISSHL) is one of the most controversial issues in otology. The aim of this study was to determine whether a delay in treatment has any influence on hearing recovery in ISSHL. METHOD This study was designed as a retrospective evaluation of an electronic patient data base of the University Hospital Zürich from January 1995 to August 2...
