He knew exactly what my 25yrs old hearing loss problem was and what needed to be done and just did and corrected my hearing instantly!
I am extremely happy that I landed on the hands of an ENT expert , " Prof.Dr. Yavus. He knew exactly what my 25yrs old hearing loss problem was and what needed to be done and just did and corrected my hearing instantly! The medical team, from reception,/admin, translators, lab techs, surgery and docs are great, these are professionals who are properly trained. My one night hospital stay in the room after my ear surgery was a five stars 🌟 🌟 🌟 🌟 🌟 experience. Very clean and quite room, with spacious washroom with all amenities in place. You can sit and work on your laptop if you can, sit and read a book or watch out through the window if you like or just lay in your hospital bed and take naps. No pain! Everything about the room was excellent! The nurses on night duty checked me every hour or less to monitor my temperature and/blood pressure. This was angelic 👌 And then I had a soft diet in the morning to break my 24hrs fast, isn't this enough care to appreciate? Doc was happy to learn I can hear! He was successful in his work.💪💪💪 If you have an ENT problem, look out for this hospital and ask for Prof.Dr Yavuz. He shows you and explains what your problem is on a projector and tells you instantly he can correct it and does that with no pain. Was half the price I would have paid in the UK. I met an Orthopaedic surgeon too to address my knees pain. Dr. Tusuf Bayram. An expert in his office. I thought I needed an MRI but no, I explained, he examined, did an x-ray and knew what was wrong, what needs to be done and did what he could. Simple! Three GP visits with an x-ray didn't see my problem but he did. If you got similar problem, please look no further than here.😃🤞 However, I had too many coordinators from both Bookimed and Hisar hospital several.months when planning my treatment. If there is anything I would ask you to improve, kindly stick to one from bookimed and one from the hospital please. To coordinate exceedingly, you need to understand a patient's concern, interest and goal. I did not meet a Neurosurgeon I should have met as planned, because he was given an appointment to meet me on a day that I was on air travelling in the night, how could this be! He had videos of my other neural conditions and had more information about my condition beforehand than the Neurosurgeon I met a day after. And I came back unsatisfied with my neural recommendation. Attached is my pic with my ear Surgeon , five days after my surgery. Look out for him!😍
Recovering my hearing loss.
I was not happy meeting a Neurosurgeon I didn't interact with during the planning months. She was physically examining me and not explaining what she was looking out for and why. And then made another test I had to ask what for and even so, the reason I was given wasn't satisfactory. I mean, it should explain what exactly she is investigating. An expert medical personnel does that. Doctors Yavus and Yusuf did!
About Bookimed service
Was good, they helped me get a cheaper hospital to address my medical conditions than a hospital I had actually found online. Only problem was the miss coordination between the initial Neurosurgeon and the day we should have met.

Hello . My husband and I flew in for an examination, to have a gastroscopy of the stomach and an MRI of the spine, the MRI still hasn’t returned the results, it’s been two weeks. Secondly, they asked to do an MRI of the entire spine, but it turned out they only did the lower back, because... Clinic coordinator Maria thought that we only needed an MRI of the lower back; all appointments were on hold for more than an hour. The appointment was for one time, they came in 1-1.5 hours later. We repeatedly asked coordinator Maria to send the result with a translation, and asked to send a disk with the MRI result. As a result, all the blame was placed on the translator that she translated the information to us incorrectly, in fact, Maria’s manner of speaking is very rude, she could simply say “It’s your own fault, you misunderstood us.” We were disappointed in the clinic. And all the disappointment was spoiled only because of the coordinator Maria, by the way, our number was blocked without sending the result. I do not recommend going to this clinic. I only wanted to speak about the clinic coordinator Maria, I wanted to post correspondence with her, but she deleted some messages and blocked my number. Inability to work with a patient, inability to listen, inability to follow through with a patient. Rude, irresponsible, evil woman coordinator Maria, correspondence was with her to this number +90 501 708 86 84. 2 weeks passed and we still haven’t received the test result. Only because of such staff we will never return to the clinic.
