Official Title: The Effects of the Drugs Used in Hypotensive Anaesthesia on Cochlea

Brief Summary: The aim of this study is to find the Effects of Anesthetics Used in Hypotensive Anesthesia on Stapes Reflex and Distortion Product Auto Acoustic Emission.

Detailed Summary: This study was aimed at evaluating the effects of dexmedetomidine and esmolol on stapes reflex and distortion product auto acoustic emission. the stapes reflex and auto acoustic emission are of considerable diagnostic significances in otolaryngology this are objective methods for the assessment of auditory function.
Sponsor: TC Erciyes University

Current Primary Outcome: distortion product auto acoustic emission [ Time Frame: postoperative 1 day ]

distortion product measurements will be performed in 1001, 1501, 2002, 3003, 4004, 6006, 7996 Hz frequencies and change from baseline in distortion product measurements at postoperative 1 day


Original Primary Outcome: Same as current

Current Secondary Outcome: stapes reflex [ Time Frame: postoperative 1 day ]

stapes muscle reflex measurements will be performed by electrical impedance. data will be taken as graphics. ıf there is an amplitude on graphic the data will be assumed as stapes reflex positive.Change from Baseline in stapes muscle reflex at postoperative 1 day


Original Secondary Outcome: Same as current
