Transthoracic endoscopic T-2, 3 sympathectomy for facial hyperhidrosis.

Twenty-five patients (20 men and 5 women) with the chief complaint of facial hyperhidrosis were treated by transthoracic endoscopic T-2, 3 sympathectomy. All patients were essentially in good health except the embarrassment of facial sweating. Fifteen of them also suffered from distressing palmar hyperhidrosis. The ages ranged from 18 to 40 years (mean age 25 years). All of them except two obtained a satisfactory improvement of facial hyperhidrosis after 3 months to 2 years of follow-up. One man demonstrated very mild ptosis in the right eye. Pre- and postoperative sympathetic skin response (SSR) revealed the absence rate from 20% to 72% with electrical stimulation (p < 0.05). This study shows that T-2, 3 sympathectomy is a choice of treatment for facial hyperhidrosis and sympathetic supply to the face may at least partly be from T-2, 3 level.
