The moment I saw the result, even with the initial swelling, I could tell the shape was exactly what I wanted

The moment I saw the result, even with the initial swelling, I could tell the shape was exactly what I wanted. It’s a great feeling. My goal was a more defined tip, and that's precisely what the surgeon delivered using an open approach. The whole process was smooth, and the staff were genuinely caring. The most difficult part of recovery so far is just having to sleep upright, which is temporary. A huge bonus is that I am breathing perfectly through my nose already. I am so grateful for the surgeon's skill and the clear communication from the team.

The hospital was first class and so was the care

The whole experience was good from airport transfers through to translator and staff. While a language barrier existed, the translator was on hand for most issues, and if not, we got by. The hospital was first class and so was the care. I am still in early recovery from the liposuction-only procedure on my chest and sides, and I feel about as expected. The only additional expense was for medication when I left, which I was aware would be the case. There has been little contact since, but they are easy to reach if I need. I felt I knew what to expect during recovery so haven’t needed to make contact.

The whole experience was good from airport transfers through to translator and staff. There was a language barrier but the translator was on hand for most issues and if not we got by with international sign language! The hospital was first class and so was the care

Ezra, the doctor’s assistant, made me feel like a family member

Ezra, the doctor’s assistant, made me feel like a family member. The staff was patient when I used my phone to translate. I am used to a pain scale and there isn't one here, which led to some uncomfortable carry-over pain. For my full arm lift with liposuction on both arms, extended past the elbow, the doctor personally did the markings and explained arm positioning for recovery. I feel better than expected. The clinic has stayed in touch. My advice: bring extra personal wipes and have medical alerts printed in Turkish.

Ezra, the doctor’s assistant, made me feel like a family member. All the staff was helpful and patient when I had to use my phone to translate something (translator is not on duty all night long).

I am used to using a pain scale and there is nothing similar here so I had some carry over pain. Nothing extreme just enough to be uncomfortable.
