Had facelift and woke up with raspy deep voice. Should I be worried about a voice box injury?

As other posters have noted, this is most likely related to the breathing tube utilized for the procedure and should resolve in due course.  A few things I would recommend: avoid caffeine, citrus juices, chocolate or other acidic food substances.  If you have a history of acid reflux that requires medication, taking the medication could help speed the healing process. Keep your Surgeon posted on your progress.

It is likely that you have some swelling from the tube used to put you asleep for anesthesia. This can occur during a facelift or any procedure where general anesthesia is used. It is not uncommon for some of my patients to have similar complaints and also a sore throat. This typically resolves within a week or two. However, if your symptoms persist then I would discuss this issue with your surgeon.
