The mmWaves can easily be wave guided into the inner ear, as 1/2 wavelength at 60 GHz is 2.5 mm.

I read a few years ago about electric fields of very high dV/dt being used to temporarily open cell walls. The patients blood was transfused through the apparatus. This was used to enhance chemotherapy, and provided some benefit.

Electric fields used in this way have long been used in commercial products, e.g. Amaxa nucleofection (https://bioscience.lonza.com/lonza_bs/CH/en/nucleofector-tec...) and Neon electroporation (https://www.thermofisher.com/us/en/home/references/gibco-cel...). I used both a decade back on mammalian cells. Bog standard electroporation has been used far longer back for bacterial cells.
