The surgeon and the clinic itself were excellent
The possibility of breathing issues was my primary concern going into this. And honestly, that has been the biggest challenge in recovery so far, with one nostril constantly feeling stuffed. My surgeon performed a closed rhinoplasty. Everything is still very swollen along the bridge, but I can already see that my nose tip appears more refined, which is a great sign. The surgeon and the clinic itself were excellent. The general staff were great, though post-op instructions could have been a bit more explicit. I'm satisfied with the medical care I received so far
Dr. Erol is an amazing doctor, his work was amazing he truly listened to my request and expectations and he was really patient and reassuring. The medical assistance team as well, they really took good care of me, they were present when i needed them.
post-op instructions could’ve been explained better

The surgeon was fantastic, earning a full 5/5 from me
My biggest concern going into this was the recovery and if I would see real changes. The procedure itself was quick, involving two passes with the MOXI laser. My skin already feels smoother to the touch, and I can definitely see my dark spots fading, which is exactly what I hoped for. The surgeon was fantastic, earning a full 5/5 from me, and the clinic itself is pristine. The most difficult part has been the aftercare; strictly avoiding sun exposure is no joke. While the staff were professional, they could have been a bit more attentive, hence the 4/5 rating. Overall, it was a solid choice for the treatment.
The professionalism and cleanliness of the hospital and the friendly staff.
The price. It can be more affordable for a lot more people. It’s really too expensive for a simple treatment.

The medical support I received was excellent
My biggest worry was what the final profile would look like, especially after having a significant dorsal hump removed. It’s very early in the recovery process, and my nose bridge is still quite swollen, so I can't really see the new shape of the tip yet. That’s to be expected. However, the surgeon and all the staff have been attentive and clear about the healing timeline, which has been reassuring. The level of care was great. While I’m waiting for the swelling to go down to see the final result, the medical support I received was excellent.
My translator Yaren was very sweet and guided me through everything I needed to know and also booked everything for me so I had no stress. My doctor Mr Mehmet also was very professional and found the internal problems for my breathing issues very quickly. Surgery went well and post operation care was optimal.

the surgeon was excellent
If you are thinking about finally fixing your profile, prioritize finding a skilled surgeon over the clinic’s administrative support. I opted for an open rhinoplasty to remove a significant dorsal hump, and at just fifteen days post-op, the bridge is already straighter as wanted. While the surgeon was excellent and the facility was clean, the staff felt a bit disorganized at times. Recovery is slow. Currently, the biggest challenge is the dry, crusty feeling inside my nose that makes breathing difficult. Despite the lingering swelling, the nose tip looks natural and fits my face well. It is early days. If you are preparing for this, my best advice is to be patient and try to relax.
The Doctor was very friendly and the result is fantastic.
The nurses did not speak a single word of englisch. And the Person from the clinic responsible for Whatsapp communication did not reply often. Also no Wifi in the Hospital.
