Will spironolactone help with my acne conglobata?

I have severe acne conglobata on my face that has been resistant to 3 rounds of accutane, pdt, and vbeam laser. The only thing I haven't tried is spironolactone. Will this help? Also could prednisone be combined with this? I cleared up for one week one time after sinus surgery. It didn't last, but it cleared.
