ABSTRACT
BACKGROUND:
Thoracoscopic T2 sympathicotomy is an effective method for the treatment of palmar hyperhidrosis. Not only are the symptoms of hyperhidrosis abolished but also the temperature of the ipsilateral palm is elevated due to the sympatholytic vasodilation after the completion of the sympathicotomy on the first side. However little is known about the temperature changes in the contralateral palm. This study was performed to evaluate the changes in both palmar temperatures during the thoracoscopic T2 sympathicotomy for palmar hyperhidrosis. MATERIAL ANDMETHOD:
Thoracoscopic T2 sympathicotomy was performed in 15 patients with primary palmar hyperhidrosis. Surface temperatures of both palms were monitored continuously and were recorded simultaneously during the 7 different stages of the operation.RESULT:
When T2 sympathicotomy was performed on the first(left) side, an ipsilateral increase with a contralateral decrease of temperature was observed. The difference in the temperature of both palms was greatest just before the sympathicotomy on the contralateral(right) side(Lt. 34.6+/-0.9degree C vs. Rt. 31.6+/-1.3degree C, p<0.0001). After the sympathicotomy on the second(right) side, temperature of the right palm was elevated. The difference in the temperature of both palms was abolished at the end of the operation(Lt.34.7+/-0.9degree C vs. Rt.34.4+/-1.0degree C, P=0.415).CONCLUSION:
When T2 sympathicotomy was performed on the first side, an ipsilateral palmar temperature increased due to the sympatholytic vasodilation. However contralateral palmar temperature decreased due to a vasoconstriction. Although the mechanism of vasoconstriction is still unknown, it is postulated that there may be a cross- inhibitory effect by the post-ganglionic neurons innervating blood vessels of the palm.
