VNG (Videonystagmography) test battery
Consists of a series of tests used to assess the balance functions of the inner ear and central nervous system. The main tests included in the VNG test battery are:
Tests Used in the Evaluation of Balance:
1. Gaze Test: This test is performed to assess whether the eyes are focused on a specific point and whether there is any deviation from this point. In this way, the presence of nystagmus (involuntary eye movements) is investigated.


- Dix-Hallpike Testi


- Supine Head Roll Test


- Deep Head Hanging Test
Purpose of VEMP Testing:
- Saccule Function: The saccule is sensitive to head movements and gravity. VEMP testing is used to measure the function of this structure and the vestibular nerves connected to it.
- Vestibulospinal Reflex: This reflex allows various muscles of the body to respond automatically to maintain balance. VEMP testing evaluates this reflex pathway.
Types of VEMP Testing:
- cVEMP (Cervical VEMP): Measures the contraction responses of the sternocleidomastoid muscle (neck muscle). It evaluates saccule and inferior vestibular nerve function.
- oVEMP (Ocular VEMP): Measures the responses of the lower eye muscles. It evaluates the function of the utricle (another structure in the inner ear that senses balance) and the superior vestibular nerve.




Purpose of the VHIT Test:
- Assessment of the Vestibular-Oculomotor Reflex (VOR): This reflex allows the eyes to remain focused on a fixed point when the head is moved quickly. If the VOR is not working correctly, it may indicate a disorder in the vestibular system.
- Detection of Peripheral Vestibular Disorders: VHIT is used to evaluate peripheral vestibular disorders, especially vestibular neuritis.
Tests Used in the Evaluation of Hearing
1. Pure Tone AudiometryIt is based on the use of pure tones to evaluate the hearing of individuals. In our clinic, pure tone audiometry, speech tests, free-field tests and quiet room are used to accurately determine hearing loss and reach the correct diagnosis and treatment.




Tests Used in the Evaluation of Tinnitus (Hearing)
In the assessment of tinnitus (ringing in the ears), various audiometric tests are used to determine the characteristics of hearing loss and tinnitus. These tests help to understand the type and severity of tinnitus and its impact on a person’s hearing. Here are the main audiometric tests used to assess tinnitus:




I had a tonsillectomy performed by our doctor, Mustafa Deniz Yılmaz. The surgery went smoothly, and although it's said to be more difficult for adults, I recovered very quickly. I'm so glad I chose Mustafa.
Hello, they told me that my parotid gland needed to be removed. I went to so many doctors that I finally decided on Dr. Mustafa. I am glad I chose Dr. Mustafa. You do not need to look for a doctor, you can choose my doctor with peace of mind without any worries.
I had a nose surgery 9 months ago by Mustafa Deniz Hoca. Both he and his team are always in touch with you before and after the surgery and provide detailed answers to questions. I am very pleased with my nose in terms of aesthetic appearance and health. Thank you and your entire team for everything.
First of all, I would like to thank my instructor Mustafa Deniz Yılmaz for his efforts. I had a nose surgery about 4 months ago. Like everyone else, I had the opportunity to research and compare the videos taken by many people who had this surgery and the perspectives of experts in their field on nose surgeries. I am very happy that I made the right decision and had surgery with my instructor Mustafa. I sincerely recommend my instructor Mustafa to everyone who wants to breathe both aesthetically and healthily and has problems.
I had a nose surgery in February. They never failed to show interest from the moment I entered the clinic until the last moment. No one even understands that I had plastic surgery. Mr. Deniz is one of the best in his field. I recommend it to everyone.
I had a nose surgery 3.5 months ago. The surgery and recovery process went great. There are a few things you should pay attention to after the surgery, they don't affect your quality of life too much. The doctor makes you feel very comfortable about that because it's not as complicated as you think. Other than that, I can breathe easily now, which is the most important thing. Also, Assistant Ayşegül Hanım gets back to you directly at any time of the day, no matter how long it has been since the surgery, if you have any questions. I'm very happy that I chose the right doctor.
I met Dr. Deniz upon the recommendation of another patient. He performed my ear surgery approximately 6 months ago with the diagnosis of Cholestatum. His care and follow-up of his patient both before and after the surgery for 6 months is commendable. I would also like to thank Dr. Deniz for his confidence in his patient and his friendly approach. I am in a much better position after the surgery, both in terms of hearing and risk of infection. I would like to thank Prof. Dr. Mustafa Deniz Yılmaz and his team.
I went to my dear teacher Deniz because of my breathing difficulties. He and his team were very cheerful and caring. My surgery was very successful and our doctor Deniz and his team were always caring throughout the process. We definitely recommend them, they are very knowledgeable, you will never regret it.
I had been experiencing a constant runny nose for a while. I decided to go to a private ENT specialist and I took a very good step. My doctor told me I had vasomotor rhinitis, which I had never heard of before. They had always given me allergy medication and sent me there. Mustafa Deniz made me feel very comfortable with the nasal wash he recommended. I had been using allergy medication unnecessarily for so long. You can go with peace of mind 😊.
I had a nose surgery 6 months ago. I am very pleased with the result. Mr. Deniz is a successful doctor in his field. You can choose him with peace of mind.
1-I had a nose surgery, there was no pressure problem with the device that was attached, when the tampon was removed I could breathe 100% from both noses, now it is completely open 2-The girl had an ear surgery. She was constantly sick because of her ear and was using antibiotics. She also had hearing problems. A tube was inserted. She has not been sick since that day, we got over a few coughs without antibiotics for the first time. She could hear well even the day after the surgery. In the first measurements, it was said that half of her hearing problem was gone. Now we are waiting for the 3-month check-up. But we do not have any problems with hearing. Thank you very much
I had a nose surgery 6 months ago with my doctor Mustafa Deniz Yılmaz. The pre- and post-operation was very comfortable. The operation was better than I thought. I received very positive comments from those around me. You can trust your doctor and his team with peace of mind. Thank you Mustafa Deniz Yılmaz.
