OBJECTIVES: Baro-challenge-induced Eustachian tube dysfunction (baro-induced ETD) is characterized by failure of the Eustachian tube (ET) to open adequately to permit middle-ear pressure regulation during ambient pressure changes. There are no well-characterized tests for identifying the condition, which makes both patient diagnosis and research into treatment efficacy challenging. This systematic review evaluates ET function tests as potential outcome measures for baro-induced ETD. DATA SOURCES: MEDLINE and CENTRAL were searched (database inception to March 2017) and reference lists reviewed for all relevant English Language articles...

We have developed a new clinical classification of acute otitis media (AOM) based on the previously proposed classifications of V.T. Palchun with co-workers (1997) and J. Jeger (1970) in which the letter near the stage of the pathological process roughly corresponds to the type of the tympanogram as follows: stage I (acute tubootitis): A, B, C; stage II (acute catarrhal otitis media): A, B, C; stage III (acute purulent otitis media, perforation stage); stage IV (acute purulent otitis media, post-perforation stage); stage V (resolution of otitis media): A - convalescence or recovery, B1 - exudate present in the tympanic cavity; B2 - persisting perforation; C - block of the auditory tube, O - the development of complications...

Subjective and objective hearing tests are used for evaluation of hearing impairments. Objective methods include impedance measurement with tympanometry and stapedius reflex measurement, otoacoustic emissions (OAE), and auditory evoked potentials (AEP). Combined with statistical analysis, the introduction of auditory steady state responses (ASSR) has enabled objective hearing tests in newborn hearing screening and automated hearing threshold assessment. The type and degree of hearing loss can be determined using the abovementioned methods...

OBJECTIVES: Human immunodeficiency virus positive (HIV+) individuals report hearing difficulties, but standard audiological tests show no, or small, changes in peripheral hearing ability. The hearing complaints may reflect central nervous system (CNS) auditory processing deficits, rather than middle or inner ear problems, and may result from CNS damage due to HIV infection or treatment. If central auditory task performance and cognitive deficits in HIV+ individuals are shown to be related, then central auditory tests might serve as a "window" into CNS function in these patients...

INTRODUCTION: Juvenile idiopathic arthritis (JIA) is a chronic autoimmune disease characterized by the presence of arthritis in children under 16 years of age for more than 6 weeks in the absence of any other known cause. The extra-articular manifestations, especially in the audiovestibular system, are related to the involvement of the joints of the ossicular chain as a result of the inflammatory process in the synovium. Previous clinical studies in pediatric patients have shown conductive or sensorineural hearing loss...
