several experienced plastic surgeons, including myself, have had excellent results in treating excessive armpit sweating with the cellulaze laser by Cynosure. there is 1-2 very small incisions (2-3 mm) per armpit. it takes about 30 minutes to perform and you can go to work the next day. it is too early to say if it is truly permanent but there are follow ups now that have shown it to last over 3 years.
