A 28-year-old female diver presented with dizziness and difficulty clearing her left ear whilst scuba diving. Her pure-tone audiometry and tympanometry were normal. Testing of Eustachian tube function revealed tubal stenosis. Video-oculography revealed a predominantly torsional nystagmus while the patient was in the lordotic position. Fistula signs were positive. High-resolution computed tomography (HRCT) of the temporal bone revealed a diagnosis of bilateral superior semicircular canal dehiscence (SCDS). Cervical vestibular-evoked myogenic potential (cVEMP) testing showed that the amplitude of the cVEMP measured from her left ear was larger than that from the right...

OBJECTIVE: This study aimed to verify cutoff values for G width (the width of bimodal peaks for the waveform obtained when measuring conductance at 2000Hz) in Japanese individuals diagnosed with Ménière's disease (MD) using multifrequency tympanometry (MFT) and to determine the relationship between the G width and ability to hear low-pitched sounds using measurements over time. METHODS: The study included 51 patients with clinically diagnosed MD, who had not undergone endolymphatic sac surgery, but had no other known ear disease (57 ears in patients aged 22-80 years were affected, and 45 ears in patients aged 18-83 years were unaffected; mean age: 53...

OBJECTIVE: Otitis media with effusion (OME) is a leading cause of difficulty in hearing in paediatric population. Otitis media with effusion must be detected and managed early to prevent conductive hearing loss in children. It was aimed to compare results of laser myringotomy and ventilation tube insertion, in terms of hearing improvement and recurrence of Middle ear effusion (MEE). METHODS: This randomized controlled trial was conducted from February 2012 to January 2015...

OBJECTIVE: To analyze acoustic absorbance using wideband tympanometry in neonates exposed to passive smoking during pregnancy. METHOD: A study comprising 54 neonates in the control group (CG - unexposed) and 19 in the study group (SG - exposed) was carried out. Subjects were submitted to the wideband tympanometry test and subsequent analysis of absorbance of 17 frequencies. RESULT: Low frequencies had a lower level of absorbance compared to high frequencies for both ambient and peak pressures, with no difference between the groups...

OBJECTIVE: Multi-frequency tympanometry and its components are extensively used to identify middle ear disorders. However, there are a limited number of studies that have attempted to determine its test-retest reliability. Thus, the present study attempted to determine the test-retest reliability of the different components of multi-frequency tympanometry. MATERIALS AND METHODS: The resonant frequency (RF), F45, and ΔG were determined three times in 40adults with normal hearing...

BACKGROUND: Eustachian tube dysfunction is a poorly defined condition associated with various symptoms and it can predispose to middle-ear disease. Balloon dilation Eustachian tuboplasty has been proposed as a treatment for Eustachian tube dysfunction. OBJECTIVE: To evaluate the subjective and objective outcomes of balloon dilation Eustachian tuboplasty in patients with recurrent, previously treated chronic Eustachian tube dysfunction. METHODS: The study was conducted on 11 patients (13 ears) who had undergone previous unsuccessful medical and surgical treatment...

Purpose: Although an interdisciplinary approach is recommended for assessment and management of feeding or swallowing difficulties, audiologists are not always included in the interdisciplinary team. The purpose of this study is to report the prevalence of middle ear and hearing problems in children with feeding and swallowing disorders and to compare this prevalence with that in typical children. Method: A total of 103 children were included in the study: 44 children with feeding and swallowing disorders and 59 children without any such disorders...

Introduction With the growing popularity of telemedicine and tele-diagnostics, clinical validation of new devices is essential. This study sought to investigate whether high-definition digital still images of the eardrum provide sufficient information to make a correct diagnosis, as compared with the gold standard view provided by clinical microscopy. Methods Twelve fellowship-trained ear physicians (neurotologists) reviewed the same set of 210 digital otoscope eardrum images. Participants diagnosed each image as normal or, if abnormal, they selected from seven types of ear pathology...

Hearing loss in patients with autoimmune diseases, such as systemic lupus erythematosus (SLE), granulomatosis with polyangiitis (GPA, Wegener's granulomatosis), or rheumatoid arthritis (RA), is controversial. Many studies lack measurements of bone-conduction thresholds to sufficiently differentiate between sensorineural hearing loss and conductive hearing loss. In addition, many studies lack control groups or comparisons to an age-related normal hearing threshold. This study investigates hearing performance with an extended audiological battery using psychoacoustic and objective measures...

OBJECTIVES: An important clinical application of transient-evoked otoacoustic emissions (TEOAEs) is to evaluate cochlear outer hair cell function for the purpose of detecting sensorineural hearing loss (SNHL). Double-evoked TEOAEs were measured using a chirp stimulus, in which the stimuli had an extended frequency range compared to clinical tests. The present study compared TEOAEs recorded using an unweighted stimulus presented at either ambient pressure or tympanometric peak pressure (TPP) in the ear canal and TEOAEs recorded using a power-weighted stimulus at ambient pressure...

OBJECTIVE: The purpose of this study was to evaluate pressurised wideband acoustic immittance (WAI) tests in children with Down syndrome (DS) and in typically developing children (TD) for prediction of conductive hearing loss (CHL) and patency of pressure equalising tubes (PETs). DESIGN: Audiologic diagnosis was determined by audiometry in combination with distortion-product otoacoustic emissions, 0.226 kHz tympanometry and otoscopy. WAI results were compared for ears within diagnostic categories (Normal, CHL and PET) and between groups (TD and DS)...

Meniere disease is a unique, progressive disease of the inner ear. The complex manifestation presents diagnostic challenges. It is difficult to diagnose due to the absence of typical presentations especially in the early stages. The cochlear symptoms often present prior to vertigo and tend to be ignored. Therefore, focusing on the cochlear symptoms and functions may provide information for early diagnosis and may protect the patients from acquiring a hearing disability. This review focused on the pure-tone audiometry, glycerin test, distortion product otoacoustic emissions, auditory brainstem response, electrocochleogram, multifrequency tympanometry, and speech audiometry, which hopefully could emphasize the importance of the symptomatic and functional findings of cochlear, and be helpful in diagnosis for Meniere disease...
