Minimal Hearing Loss: From a Failure-Based Approach to Evidence-Based Practice.

Purpose: A representative sample of the literature on minimal hearing loss (MHL) was reviewed to provide evidence of challenges faced by children with MHL and to establish the need for evidence-based options for early intervention.

Method: Research articles published from 1950 to 2013 were searched in the Medline database using the keywords minimal hearing loss, unilateral hearing loss, and mild hearing loss. References cited in retrieved articles were also reviewed.

Transient-evoked otoacoustic emissions from ears with tympanostomy tubes.

Objective: Otoacoustic emissions (OAEs) are low-level acoustic signals which emanate from the cochlea and can be recorded in the ear canal. The two types of OAEs are spontaneous and evoked otoacoustic emissions.

Methods: In this retrospective study, transient-evoked otoacoustic emissions (TEOAEs) were measured in 385 ears from 204 children with normal hearing and tympanostomy tubes.
