The purpose of this study is to measure the potential effects of surgical drilling noise and/or vibration exposure on the hearing in the ear contralateral to the surgical site during skull-based surgeries
High-speed drills that are capable of producing elevated levels are used during skull based surgeries (Hilmi et al., 2011; Yu et al., 2014). Recently, it has been shown that surgical drilling may have a temporary effect on the amplitude of the otoacoustic emissions of the ear contralateral to the surgical site (Baradaranfar et al., 2015; Shenoy et al., 2015), however the temporary effects of surgical noise or vibration on the hearing of the non-surgical related ear needs to be better quantified. This study aims to to measure the potential effects of surgical drilling noise and/or vibration exposure on the hearing in the non operative ear, during surgical site during skull-based or mastoid surgeries. As part of the study patient will receive Audiometry for extended high frequencies, DPOAE, ECochG before and after the procedure.

This study measures sounds produced by the sensory receptors of the inner ear called hair cells. These sounds are called otoacoustic emissions and one special case the investigators are st...
The purpose of this study is to find out how often hearing loss occurs in patients with retinoblastoma after receiving treatment with intra-arterial carboplatin.
Twenty patients with tinnitus and a typical noise-induced hearing loss (NIHL) audiogram were included. Each subject underwent an otoscopic examination, distortion product otoacoustic emiss...
Hearing loss is one of the most common congenital anomalies . It has been shown to be greater than that of most other diseases and syndromes (eg, phenylketonuria, sickle cell disease) scre...
Hearing loss is one of the most common congenital anomalies. Early Intervention at or before 6 months of age allows a child with impaired hearing to develop normal speech and language.Audi...
Distortion product otoacoustic emissions (DPOAEs) measured in the ear canal are composed of OAEs generated by at least two mechanisms coming from different places in the cochlea. Otoacoustic emission ...
Purpose Cannabis is a widely used drug both medically and recreationally. The aim of this study was to determine if cannabis smoking is associated with changes in auditory function, as measured by beh...
Purpose Many children with severe intellectual and developmental disabilities are at a higher risk for hearing loss than their peers who are typically developing. Unfortunately, they do not consistent...

Distortion-product otoacoustic emissions (DPOAEs) are currently used in many newborn hearing screening programs as the initial hearing test, typically testing frequencies between 1 and 4 or 6 kHz, b...
Self-generated faint acoustic signals from the inner ear (COCHLEA) without external stimulation. These faint signals can be recorded in the EAR CANAL and are indications of active OUTER AUDITORY HAIR CELLS. Spontaneous otoacoustic emissions are found in all classes of land vertebrates.
Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
An accumulation of ENDOLYMPH in the inner ear (LABYRINTH) leading to buildup of pressure and distortion of intralabyrinthine structures, such as COCHLEA and SEMICIRCULAR CANALS. It is characterized by SENSORINEURAL HEARING LOSS; TINNITUS; and sometimes VERTIGO.
Hearing loss due to damage or impairment of both the conductive elements (HEARING LOSS, CONDUCTIVE) and the sensorineural elements (HEARING LOSS, SENSORINEURAL) of the ear.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
