I don’t see it very often at all!
It has a higher rate of infection and also poor pocket precision as it’s harder for the surgeons to create them, although some specialise in those incisions s must be good!
All I can contribute, when I had my BA inframmary incision, I had a mole removed from my underarm with one stitch, and the dressing on my underarm bothered me the most as I couldnt wash it (whilst I could sit in the bath to wash the rest of me) so one armpit gets stinky and hairy, so gross!
I’m sure it has its positives though, hopefully someone will be along to share their experience!
