The support staff were truly exceptional, making a very difficult situation feel much more manageable
If you are looking into this clinic for prostate cancer treatment, I can offer my perspective. The support staff were truly exceptional, making a very difficult situation feel much more manageable, and the clinic facilities were solid. I would say my experience was overall good. However, there were some communication hurdles to navigate. While general language support was adequate, I felt this was a weak point during crucial consultations with the surgeon himself, which led to some uncertainty. This is the main reason for my lower rating for the doctor. It's just something to be prepared for. I am now focused on my recovery.

I had a wonderful experience
Dr. Malikgazi was very dedicated and friendly; I would always want to go to him for any future plastic surgery. The hospital is beautiful with very helpful staff, and I thank the interpreters Nurcan and Berk who helped me the entire time. The food was my only issue. The portions were very small, and it was difficult to get more until I insisted. It is still too early to see the final result of my rhinoplasty, which involved a specific technique to change certain parts of my nose. I did have an extra expense for an echocardiogram because of a previous heart surgery. You don't have to bring anything; the hospital and Hotel Uranus are luxury.

I foundevEverything w the food there very bad and the portions very small. If you ask for more food, they bring absolutely nothing. I insisted on a bit more food and eventually they gave me an extra portion.

Whether it's the doctors, nurses or reception staff, many other hospitals should take inspiration from the Turkish hospital model
The quality of the hospital service is second to none, with well-organised, highly competent services that are always available to patients. Whether it's the doctors, nurses or reception staff, many other hospitals should take inspiration from the Turkish hospital model. The hospitals are like luxury hotels, you feel good, you are looked after and followed throughout your stay. Finally, the money I spent there was really justified. Thank you to everyone who looked after me during my 14-day stay. Of course I recommend Istanbul Memorial Hospital. Antonio. M

The consultation with the doctor was decisive for me
The consultation with the doctor was decisive for me. He not only answered questions but also thoroughly explained the risks of the combined surgery, honestly assessed my initial data for choosing implant sizes, and justified why a lift with a periareolar incision would be best in my case. I am currently in the recovery stage, and my condition is exactly as I expected after all the explanations. Importantly, there were no additional expenses beyond the amount paid. Everything went according to plan.
