title: Factors affecting long-term satisfaction after thoracic sympathectomy for palmar and plantar hyperhidrosis. Is the sudomotor reflex the only villain?
abstract: The main objective of this study was to determine if there are variations in the level of improvement of the palmar and plantar hyperhidrotic symptoms, as well as the incidence and intensity of the sudomotor reflex, throughout the seasons of the year, after thoracic sympathectomy for hyperhidrosis. The study also looks for the real impact of these variables in the long-term satisfaction. A cohort of 75 patients was followed through distinct seasons. A multivariate analysis was performed to identify possible variables responsible for dissatisfaction. Both the palmar (P=0.002) and plantar (P<0.001) symptoms and the presence and the intensity of the sudomotor reflex varies significantly throughout the seasons of the year. The sudomotor reflex was the main factor associated with low satisfaction in our patients in the summer (P=0.025) and winter (P<0.001) but in spring the lack of improvement in the hyperhidrosis in the foot was the unique factor related to dissatisfaction (P<0.001). The sudomotor reflex is the main negative factor in the summer and in the winter, independent of its intensity. However, at least in spring, the lack of removal of the plantar symptoms had a negative impact on satisfaction.
