How safe is the use of mesh in revision surgery?

It is incredibly safe if done with proper technique by a well-trained plastic surgeon. I recommend seeing a board-certified plastic surgeon (American Board of Plastic Surgery). Ideally, this surgeon has also completed an accredited aesthetic fellowship (The Aesthetic Society).

Dear GetGab,
bottoming out occurs when the implant falls below the current breast crease or inframammary line. It's more likely to happen with inframammary incisions, which is why I try not to use the inframammary approach to any breast surgery.
Bottoming out can also occur if an implant is too large for the breast pocket. That is why it is important to choose an implant size that's correct for your body. I perform numerous measurements in the office to determine optimal implant size for my patient's bodies.
If you are concerned, please check it with your plastic surgeon for reassurance and to further discuss your options and possibility of revision.

I recommend explantation and lift using The Bellesoma Method. The implants are removed, your breast tissue is reshaped creating upper pole fullness, elevated higher on the chest wall and more medial to increase your cleavage. Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained if not injured during your previous surgery. Later, fat transfers can be performed if additional volume is desired.

Best Wishes,
