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 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.
About 10 months ago, Dr. Deniz performed my nose surgery. I wanted to wait a while to comment. First of all, it was a difficult surgery for me to decide, because I was very afraid of the surgery. I made my decision by considering the comments here. The surgery process went better than I expected. I had no pain or bruising, but I had a lot of swelling due to my nose skin. My nose has recently gotten rid of the swelling and settled down. I went there mostly for aesthetic purposes, but now I can breathe much better. I was very pleased with both Dr. Deniz's interest and sincerity, and the healthy and beautiful result we got. I think those who are undecided and those who have fears like me can trust Dr. Deniz with peace of mind.
I have been having serious difficulties breathing for a long time due to nasal congestion. My nasal passages were almost completely blocked. As a result of my detailed research, Prof. Dr. I had the opportunity to meet Mehmet Deniz Yılmaz. From the first examination, his professionalism, knowledge and sincere approach gave me great confidence. My surgery was extremely successful. The discomforts I experienced due to polyps have completely disappeared. I can breathe easily now. I cannot thank the doctor and his team enough. I would like to thank each and every one of them for their care and attention during this process.Prof. Dr. I recommend Mehmet Deniz Yılmaz and his team wholeheartedly.Thank you, dear Doctor. Thank you very much 🙏🏻
When it comes to the teacher, he is the best in Antalya. How many places have I been to, how many doctors have I seen, what have I suffered over the years? Many doctors in Ankara, Istanbul, Antalya, none of them could even provide relief. May God bless my teacher Mustafa. We found him on the ground while looking for him in the sky. I recommend him to everyone with Meniere's disease.
My wife had apnea and snoring problems. Before Mustafa, other doctors said that about 5 different surgeries would need to be performed. We were worried and searched for another doctor. Looking at the comments here, we trusted Mustafa Hodja. Thank God, he said about 3 months ago that only closed nose surgery would be enough, and over time, the apnea would go away on its own. The surgery lasted 2.5 hours. My wife was discharged in the evening. There was no bruise or swelling on her face. She recovered within a week and returned to work. Meanwhile, his snoring decreased significantly and his apnea disappeared. Well done to our teacher. He is a very professional doctor and we recommend him to everyone.
My 2.5-year-old daughter could not breathe and her sleep was interrupted due to her adenoid problem. It was resolved in about 1 hour. Even right after the surgery, he started breathing very easily. Thank you so much, I'm glad to have you
We would like to thank our doctor and thank Ms. Ayşegül for her support before and after the surgery. I wish you a healthy day.
