Background: This study aims to investigate the effectiveness, success and complication rates of three different video-assisted thoracoscopic sympathectomy procedures performed for the treatment of primary focal hyperhidrosis; excision, cauterization and clipping.

Methods: We retrospectively evaluated the records of 60 patients (33 males, 27 females; mean age 25.1±6.4 years; range 16 to 43 years) with primary focal hyperhidrosis and treated with videoassisted thoracoscopic sympathectomy between January 2010 and December 2013. The patients were treated bilaterally at the same session: the sympathetic chain and ganglia were excised from the spinal cord segments of T2-T4 in 20 patients (group 1), cauterized in 20 patients (group 2), and clipped in 20 patients (group 3). The procedural success and complication rates were compared among the groups.

Results: Sympathectomy was successfully performed in all patients. The mean operation time was found to be significantly shorter in group 2 (42.5±7.1 min) and group 3 (36.9±7.8 min), compared to group 1 (51.1±8.4 min) (p<0.05). Compensatory hyperhidrosis developed in 17 patients (28.3%) and was comparable among all groups (p<0.05).

Conclusion: Our study results suggest that excision, cauterization, and clipping are effective and reliable in the treatment of primary focal hyperhidrosis. Based on our experience, we believe that sympathectomy with video-assisted excision may be preferable for the treatment of primary focal hyperhidrosis.
