What are the risks of an adenoidectomy?

The risks of an adenoidectomy are rare but include:

  • Failure to resolve the underlying breathing problems, ear infections, or nasal drainage
  • Excessive bleeding (very rare)
  • Permanent changes in vocal quality
  • Infection
  • Risks from the use of anesthesia

Your doctor should thoroughly explain all of the risks of adenoid removal and answer your questions before you agree to the procedure.
