Recovering from throat surgery such as tonsillectomy, uvuloplasty, and or base of tongue surgery can be excruciating. There is no pain therapy that is out of bounds. I give 12 mg Decadron intra operatively and generously inject 0.23% Marcaine with 1/200,000 epi into the operated on area.
Topically Gelclair can be very helpful. It forms a barrier (similar to but also superior to Carafate). Magic mouth rinse with topical anethestics or Numbing throat sprays (Chloraseptic) can be temporarily helpful.
