How long does it take for the corrugator muscle to grow back? Could I have this procedure done multiple times?

because the muscle sits close to the eyelid, a near-total resection of the corrugator can be done through the eyelid under direct vision, which is more precise than when done through a browlift incision and endoscope. A complete muscle resection along with placement of a spacer such as fat can prevent regrowth of the muscle. In reality, some muscle reattachment is seen over time, but it's definitely weaker than prior to surgery and less frequent botox is usually needed (and with less frequency).

Thank you.  Cutting the corrugator muscle is done in conjunction with a brow lift.  The muscles can grow back as early as 3 months-1 year, depending on how aggressive the cutting is. I prefer regular botulinum toxin as it is a non-invasive result and yields beautiful results.  I wish you well.  Please see an expert.

Thank you for sharing your excellent question. If a muscle is either cut or resected it will not grow back and overall should atrophy/fibrose with time.  Because this can lead to central forehead depression this procedure is done, but with less frequency.  From your narrative it seems as if you would benefit from a higher dosing of Botox, or a different neuromodulator. Hope this helps.

In your age treatment with Botox should have priority. However, you have to be sure that you are receiving appropriate amount of Botox in designated area by someone who is familiar with muscle anatomy and individual variations. If this treatment doesn't provide satisfactory result, endoscopic resection of corrugator and procerrus muscles will provide permanent improvement. To my knowledge once muscle is removed it will not grow back. In person consultation with a board certified plastic surgeon with experience with endoscopic brow lift and Botox would help. Good luck.

Strong corregator muscle treatment. Sectioning and removal  of part of the muscle will prevent recurrence. This should be done through the Irregular Trichophytic Forehead Incision and can be combined with a  brow lift if needed.  I invented this procedure more than 40 years ago and have done hundreds without complication others than a few pimples as hair grows through the incision preventing a visible scar. See a very experienced surgeon familiar with this technique and you can decide when the timing would be right for you.
