After extensive research, I came across Dr. İlker Manavbaşı. I had been considering liposuction combined with J-Plasma on multiple areas of my body for a long time—it’s been a dream of mine for years, especially since regular exercise and dieting no longer made a difference. I’m extremely satisfied with the care and the entire process. I placed my full trust in Dr. İlker without knowing him personally, and I was not disappointed. His consultation was excellent and made me feel confident in my decision. Now I just need to continue healing, and I’m very curious to see how the final results will turn out. A heartfelt thank you to everyone who supported me during this time—and especially to the wonderful Dr. İlker.

I've had some procedures done by Dr. İlker Manavbaşi 2 times. He's very experienced, very attentive to what the patient wants, very gentle and respectful, and he's doing the best he can to meet the patient's expectations while keeping his professional approach to any procedure. I loved that he's not pushing anyone towards exagerated results, but on the contrary, he's making sure he highlights his approach and recommendation towards natural looking results that would suit the patient's figure better. He makes sure he will explain what would be realistic or not, what are the risks and the expected outcomes for everything the patient choses to have done. His whole team has provided a lot of care for me and they were always available for any of my needs or requests. The nurses and the other doctors that offer post surgery care are very sweet and professional people as well. I'm always recommending him and his team to anyone I know that wants to have a procedure done.

I had breast implants yesterday what a lovely man dr is he talked me through the whole process made me feel 1 million percent comfortable even made me smile when I was nervous. I’m amazed with my results and I would highly recommend everyone to go to him. Also his assistant was so nice such a lovely helpful lady. Thanks again I’ll be back soon for you to work your magic

I have flown over from Australia after hours of research to find a reputable Dr as I was searching for one of the best in the industry. Not only did I get the best in my eyes but he was the most genuine, realist Dr. Firstly I’m going to start about the process where I contacted via WhatsApp and had all the information I needed at a promptly time. I had booked, then changed my booking date, and changed again and they were so nice about it and found me the dates I could travel. Secondly, I was picked up from airport and taken to the hotel and was greeted the next day by the whole team. They are so friendly and helpful. They all speak English and use a translator if needed. The hospital was clean and walking distance from the hotel. Thirdly, Dr Ilker Manavbasi has performed his magic with my breast operation. I had implants that needed removal, a breast lift and a breast augmentation. I told him what I wanted and he took the time to tell me what was suitable for my body and I’m so grateful I took his advice. Dr Ilker had consulted me for another procedure that I wanted and with his professional opinion and genuine heart, I didn’t need that operation and didn’t book for it. I could see that with honesty, I could trust him. I 110% refer Dr Ilker and his team. Do your research elsewhere but I would have Dr Ilker at the top of your search. Thank you Dr Ilker, I will see you before I return to Australia again 👃 🙏🏼 🧿 🥰

We would like to thank the entire team of Dr. Manavbasi for their work. Very skilled and clear in agreements. The result of the operation is fantastic. The aftercare is also more than excellent. Havva is always available and very fast in her actions. Thanks again for your efforts and keep up the good work!
