Hello flutedude,Thanks for your question.Placement of facial implants and performance of a facelift does temporarily affect facial musculature. Most patients describe temporary limitations in facial motions due to inflammation, swelling, and postoperative pain. Two major risks to facial plastic surgery are numbness and injury to the Facial nerve. In your situation, injury to sensory nerves around the mouth can change how you feel pressure when playing the flute. Injury to branches of the Facial nerve cause partial (sometimes permanent) dysfunction of facial muscles. The most common nerve injured with facial implants is the Mental nerve to the lower lip during chin implant placement. The result is a numb lower lip segment. The most common Facial nerve branches injured during facelift (though rare) are a buccal branch or marginal mandibular branch injury depending on technique. Injury to either branch affects the corner of the mouth function.I would recommend consultation with a plastic surgeon to discuss your particular case. If playing the flute is of significant importance and these risk seem too great to you, it may be best seek alternatives to surgery.Good luck,Dr. Shah
