“…The level of transsection usually comprised T2-T3/T4 for palmar hyperhidrosis [4,17], and it was assumed that T4 or even T5 should be included in cases of axillary hyperhidrosis [8,16,17]. For palmar hyperhidrosis, limited sympathicotomy has been recommended ranging from T2 and T3 transsection to T2 or T3 severance [1,5,7,8,14,20]. Likewise, a variety of transsection levels have been proposed for axillary hyperhidrosis, ranging from T2 to T5 at different combinations [7,8,12,14,16].…”
