If i'm having an adenoidectomy, will my voice change?

N ot usually: This is an excellent question. If the adenoid is very large, you might experience a temporary change in the quality of your voice. If there is no palatal insufficiency, it is unlikely that any permanent change will occur. I am basing the answer on adenoidectomy in children. It is quite rare for an adult to require an adenoidectomy, unless perhaps a biopsy is being performed. No voice change.
