Objective: The purposes of these study were to evaluate the changes of temperature and sympathetic skin response (SSR) before and after sympathectomy in patients with palmar hyperhidrosis and to quantify long standing effect of sympathectomy.
Method: The SSR and skin temperature were measured before, one day and 30 days after thoracoscopic sympathectomy. SSR was recorded from palm and sole bilaterally. Temperature was recorded on 9 sites of each hand and 11 site of each sole. Patient's satisfaction with operation was assessed by 10-point scale.
Results: One day after sympathectomy, the amplitude of SSR was significantly decreased and latency of SSR was delayed in all cases on bilateral palm and sole. However, after sympathectomy 30 days, the amplitude of SSR was normalized in all cases on bilateral sole. All patients who had undergone sympathectomy showed significant clinical improvement. The temperature increased dramatically over 3oC on postoperation 1 day and maintained 1.72oC higher in post-operation 30 days than pre-operation on both hands. There was no significant difference of temperature among pre-operation and post-operation 1 day and post-operation 30 days on sole.
Conclusion: Our study proved effect of thoracoscopic sympathectomy to the patients with palmar hyperhidrosis objectively and quantified the decrement of sympathetic tone. Further study is needed for long term follow up over 2 months or more. (J Korean Acad Rehab Med 2002; 26: 543-549)
Objective: To observe the change of sympathetic skin response (SSR) before and after sympathectomy in patients with idiopathic palmar hyperhidrosis and to find the usefulness of SSR for assessment of the effects of sympathectomy
Method: The SSR was measured in 20 patients with palmar hyperhidrosis and 20 normal control group. Ten days after thoracoscopic sympathectomy, SSR was also measured. A 50∼150 V stimulus was applied over the median nerve and SSR was recorded on bilateral palms and soles with Viking IV (Nicolet Biomedical Ins., U.S.A.). Patient's satisfaction with operation was assessed by questionnaire.
Results: Absent or unstable SSR recordings rate was increased and amplitudes of SSR were significantly decreased in patients with palmar hyperhidrosis compared with control group. After sympathectomy, SSR was absent in all cases on bilateral palms and these results were correlated with clinical improvment. All patients who had undergone surgery showed significant clinical improvement for palmar hyperhidrosis and about 75% of the cases were found to have compensatory sweating from other site of the body.
Conclusion: Abnormal sympathetic nerve system responses were observed in patients with palmar hyperhidrosis. SSR recordings and clinical manifestations were influenced by sysmpathectomy.
