When they did mine (at the Royal London, Whitechapel, The saga of which is documented in Mudcat in about 2000) they told me it would be Keyhole, but warned me that if, when they looked , it was inflamed, they would do the full job, so not to be too surpised at the size of the scar!! When I came to and noticed I had a larger than expected scar, still under the influence of anaesthetic ( which famously lowers ones inhibitions and ones vocabulary into the gutter) I loudly asked " Keyhole?? keyhole? Well. what size was the F***ing Key???" for some reason this caused the surgeon and the nurses to collapse into hysterical laughter!!!
