Here I am again to give your my advice :-)
1. I would go for [ABC surgery: Pictures before and after] that is in case the entire page is about the surgery pictures.
2. More ideas? - Check if there's any search volume to [ABC surgery pictures], [ABC surgery stages], [ABC surgery details], [pictures of ABC surgery], [How ABC surgery is conducted]
3. Replace "surgery" with "operation" to see which term gets more searches.
4. On the page itself diversify keywords based on the topic, and try not to use the same phrase you put in the title tag.
Hope it helps.
