Thoracoscopic Sympathicotomy for Disabling Palmar Hyperhidrosis: A Prospective Randomized Comparison Between Two Levels

R2 and R3 sympathicotomy for massive palmoplantar hyperhidrosis are highly effective, with low recurrence and incidences of severe CH. R2 tends to have a higher level of CH vs R3, and a higher incidence of dramatic failures is suggested in R3 patients, for which reoperation at the R2 level will likely be curative.
