From: Retroperitoneoscopic lumbar sympathectomy for the treatment of primary plantar hyperhidrosis
Comparison between preoperative & postoperative plantar skin temperature using infrared thermal camera. Postoperative plantar skin temperature B increased compared with preoperative one A due to decreased plantar perspiration after sympathectomy (Overall plantar temperature: 36.4 °C → 38.5 °C, highest temperature: 38.2 °C → 40.6 °C, lowest temperature: 26.8 ℃ → 28.5 °C)
