The aim of this study was to investigate the risk of sensorineural hearing loss (SNHL) and the relationship between SNHL and radiation dose to the cochlea and frequency range of hearing loss in patients with head and neck cancer. Pure tone audiometry at 250-12,000 Hz was performed on 29 patients diagnosed with head and neck tumours who were treated with(More)
INTRODUCTION Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of(More)
Background and Aim: Motion sickness (MS) is usually generated when there is a mismatch between the senses which serve balance. One of these senses is related to vestibular system, so it is highly possible that MS reflects in vestibular test results. But there are some conflicts in correlation between vestibular findings and MS. Thus, the objective of this(More)
The biological effects of omega-3 and omega-6 fatty acids are determined by their mutual interactions. This interaction extremely affects various functions. Lower consumption of omega-3 during gestation leads to various disorders, even in hearing. We aimed to assess the effect of low omega-3/omega-6 ratios on auditory nerve conduction. In this experimental(More)
INTRODUCTION Omega-3 fatty acid, particularly in the form of fish oil, has a structural and biological role in various systems of the body. The auditory and nervous systems are both influenced by omega-3 fatty acids, with omega-3 deficiency having devastating effects on both systems. Numerous studies have attempted to investigate this further. This study(More)
Background and Aim: Auditory temporal resolution skill is calculated according to the minimum required time to analyze or integrate acoustic events. This skill, which is essential for speech perception, was evaluated by gap detection tests. The aim of this study was to determine the presence or absence of any differences between the right and left ear in(More)
Background and Aim: Caffeine at low doses blocks adenosine receptors. These receptors are present in all parts of the body including auditory and vestibular system. This study aimed to evaluate the effects of caffeine on cervical vestibular evoked myogenic potential (cVEMP). Methods: In this interventional double-blind study, 40 cases (20 females and 20(More)
INTRODUCTION Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all(More)
PURPOSE The aim of this study was to generate the dose-response curves by six normal tissue complication probability (NTCP) models and ranking the models for prediction of radiation induced sensorineural hearing loss (SNHL) caused by head and neck radiation therapy (RT). MATERIALS AND METHODS Pure tone audiometry (PTA) was performed on 70 ears of patients(More)
