-Las zonas de piel correspondientes a los ganglios aun no han sido claramente definidas.
-Anhidrosis en: manos(98,1%), axilas (73.58%), brazos (39.62%), frente (20.75%), barbilla, mejillas, cuello, nuca (16.98%), lados del pecho (13.2%), pecho (7.54%), espalda (1.88%). 
-El territorio de influencia del T2-T3 es mas extenso de lo que previamente se ha descrito por los clasicos estudios de anatomia. El area cutanea inervada por el T2-T3 se extiende a zonas influenciadas por el T1 en un 20,75% de los operados de hh-palmar

The autonomic nervous system adjusts sweating on the body's skin surface. The skin areas corresponding to the various sympathetic ganglia are not yet clearly defined. The purpose of this study was to define the skin areas corresponding to the T2 and T3 sympathetic ganglia. METHODS AND MATERIALS: We performed bilateral thoracic sympathicolysis endoscopically on the T2 and T3 ganglia of 50 patients with primary hyperhidrosis. All answered a questionnaire before surgery and at least two months later. The questionnaire asked about sweating at different points, but in order to estimate the cutaneous projection of T2 and T3 we only analyzed anhidrotic regions. RESULTS: Denervation resulted in anhidrotic hands (98.11%); axillas (73.58%); arms (39.62%); forehead (20.75%); chin, cheeks, neck and the nape of the neck (16.98%); sides of the chest (13.2%); front of the chest (7.54%); and back (1.88%). CONCLUSIONS: The territory influenced by the T2 and T3 sympathetic ganglia is more extensive than has been described by classical anatomical studies. The cutaneous area innervated by the sympathetic T2 and T3 ganglia extends to zones influenced by T1 in up to 20.75% of patients with primary hyperhidrosis.
