Assessment of acute otitis externa and otitis media with effusion performance measures in otolaryngology practices.

29 Sep 2008 OBJECTIVE: To evaluate the acute otitis externa and otitis media with effusion performance measure sets in a clinical setting and provide preliminary data on measure compliance. STUDY DESIGN AND SETTING: Quality improvement study. SUBJECTS AND ... Read more...

Absent otoacoustic emissions predict otitis media in young Aboriginal children: a birth cohort study in Aboriginal and non-Aboriginal children in an arid zone of Western Australia.

26 Aug 2008 BACKGROUND: Otitis media (OM) is the most common paediatric illness for which antibiotics are prescribed. In Australian Aboriginal children OM is frequently asymptomatic and starts at a younger age, is more common and more likely to result in ... Read more...

Changes in transient-evoked otoacoustic emission levels with negative tympanometric peak pressure in infants and toddlers.

30 Jul 2008 OBJECTIVES: Otoacoustic emission (OAE) testing is now a standard component of the diagnostic audiology protocol for infants and toddlers and is an excellent tool for detecting moderate-to-profound cochlear hearing loss. Detection of hearing loss is ... Read more...

Technical information about 'Acoustic Impedance Tests'

Definition: Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).
