Clinical Trial Summary

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

Description:

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.

Eligibility

Inclusion Criteria:

• participants are undergoing a skull-based or mastoid surgery for treatment of an affected ear

• participants have normal or near-normal hearing thresholds in the un-operated ear

Exclusion Criteria:

• participants have hearing loss (PTA > 40 dB HL) in pure tone audiometry testing before surgery in the un-operated ear

• participants have medical conditions after the surgery which prevents having hearing tests

• participants have abnormal tympanometric results

Related Conditions & MeSH terms

• Deafness
• Hearing Loss

Intervention

Diagnostic Test:
• Distortion product otoacoustic emissions (DPOAE)
Audiometry for extended high frequencies, DPOAE, and, ECochG measurements will be collected before and after skull-based surgeries.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with a Difference of 5 dB or more between Pre- and Post-surgery DPOAE Measurements at any Frequency	DPOAE measurement using Interacoustics Titan DPOAE440 measurement tool is 5dB or greater from pre-surgery measurement to post-surgery measurement	pre-surgery, immediately after surgery, up to one month after surgery
Primary	Number of Participants with No change between Pre- and Post-surgery DPOAE Measurements	DPOAE measurement using interacoustics titan measurement tool has not changed or is less than 5dB from pre-surgery measurement to post-surgery measurement	pre-surgery, immediately after surgery
