The purpose of this study was to determine whether localization errors were greater in cases of right ear unilateral simulated conductive loss, as compared to left ear simulated conductive loss of the same degree and configuration. Thirty adults were asked to localize a 3-kHz warbled pure tone with their left and right ears alternately occluded with an earplug. Significantly greater localizatio...

BACKGROUND The Auditory steady state response (ASSR) provides a frequency-specific and automatic assessment of hearing sensitivity and is used in infants and difficult-to-test adults. OBJECTIVES The aim of this study was to compare the ASSR thresholds among various types (normal, conductive, and sensorineural), degree (normal, mild, and moderate), and configuration (flat and sloping) of heari...

Introduction Oculo-auriculo-vertebral spectrum, also referred to as Goldenhar syndrome, is a condition characterized by alterations involving the development of the structures of the first and second branchial arches. The abnormalities primarily affect the face, the eyes, the spine, and the ears, and the auricular abnormalities are associated with possible hearing loss. Objective To analyze the...

OBJECTIVE To assess long-term complication rate and parental satisfaction of osseointegrated bone conduction hearing implants (OBCHIs). STUDY DESIGN Retrospective chart review of children undergoing OBCHIs. METHODS A retrospective chart review of children undergoing OBCHIs for the treatment of conductive, mixed, and single-sided sensorineural hearing loss in children. RESULTS Forty-five s...

AIM to analyze the audiological profile of elderly patients seen in a clinic from an audiology school clinic in the city of Belo Horizonte. METHODS we studied all the charts from the patients who underwent audiologic assessment from April of 2004 and August of 2007 in an audiology clinic in the city of Belo Horizonte. RESULTS We studied the 313 audiological tests from patients 60 years of a...

BACKGROUND Hemifacial microsomia (HFM) is a common craniofacial disorder characterized by a wide spectrum of anomalies, including conductive hearing loss due to external and middle ear deformities. However, the prevalence of sensorineural hearing loss (SNHL) as well as facial nerve dysfunction is underappreciated. OBJECTIVE To determine the frequency of auditory and facial nerve dysfunction a...

UNLABELLED Temporal resolution is essential to speech acoustic perception. It may be altered in subjects with auditory disorders, thus impairing the development of spoken and written language. AIM The goal was to compare temporal resolution of children with normal hearing, with those bearing conductive hearing loss and auditory processing disorders. MATERIALS AND METHODS The sample had 31 c...

Hearing loss is a common symptom in Fabry disease, but neither its natural course nor its aetiology has been defined precisely. The aim of this study was to provide a detailed epidemiological description of hearing impairment in patients in the Fabry Outcome Survey (FOS), which is the largest available database of Fabry patients. Questionnaires were completed by 566 Fabry patients, of whom 316 ...

Conductive hearing loss, produced by otitis media with effusion, is widespread in young children. However, little is known about its short- or long-term effects on hearing or the brain. To study the consequences of a conductive loss for the perception and processing of sounds, we plugged the left ear canal of ferrets for 7-15 months during either infancy or adulthood. Before or during plugging,...

Otosclerosis is an otic capsule disorder that leads to progressive conductive and/or sensorineural hearing loss due to stapes footplate fixation and cochlear bone involvement. The disorder is bilateral in 70% of patients and it usually starts between the third and fifth decade. One of its characteristic clinical findings is Schwartze sign which refers to a reddish discoloration over the promont...
