CAN SWEATY PALMS BE CURED?

Yes, sweaty palms can be cured by an operation called minendoscopic sympathectomy (MES). This operation interrupts the abnormal increased signals to the hands by precisely burning a nerve relay station called the T2 sympathetic ganglion. This operation is recommended for those who are genuinely troubled by sweaty palms at work and socially and who have not found medical treatment useful. MES is the latest method for the minimally invasive treatment of sweaty palms. Older operations include video-endoscopic syrnpathectomy (VES) and open cervical and transaxillary sympathectomy.

HOW IS THE MES OPERATION DONE?

The operation is done under general anaesthesia. A tiny nick (about 3mm in diameter) is made in each armpit. It is through this nick that the mini-endoscope (similar to a telescope) is introduced. Through the endoscope the surgeon burns the T2 sympathetic ganglion. The surgery takes approximately 1 hour. At the end of the surgery a single stitch is used to close the nick in the armpit.

HOW LONG DO I HAVE TO STAY IN HOSPITAL?

Generally you come into hospital the night before surgery. The operation is done early the next morning and you can be discharged later that same evening once you have recovered from the general anaesthesia. The other option is to be admitted to Day Surgery in the late morning, have the MES in the afternoon and be discharged the same night.

WHEN CAN I RETURN TO WORK AFTER SURGERY?

You can return to work the next day after surgery if you want to. Your single stitch in each armpit will be removed about 1 week after surgery.

HOW MUCH PAIN AND DISCOMFORT IS THERE AFTER SURGERY?

The incisions in your armpit are very small with this method. Pain and discomfort is therefore very much less than the older method. Also the very small nick in the armpit leaves an almost inconspicous scar.

WHAT IS THE SUCCESS RATE FOR MES SURGERY?

The success rate is approximately 98% for MES surgery for sweaty palms.
