Introduction Primary palmar hyperhidrosis is a disabling problem that affects young age groups and usually continues for years without an effective treatment. It is usually accompanied by plantar hyperhidrosis and to a lesser extent by axillary affection. We have tried to improve the efficacy of percutaneous radiofrequency ablation of upper thoracic sympathetic ganglia via imitating what thoracoscopic surgeons do in endoscopic thoracic sympathectomy. Patients and methods A total of 40 patients with primary hyperhidrosis were randomly classified into two groups. Group Tb (n=20) underwent thermocoagulation of sympathetic chain on vertebral body. Group Th (n=20) underwent thermocoagulation of sympathetic chain on the head and neck of ribs. Hand temperature and dryness were followed up during the procedure and on the following intervals: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months after the procedure. Results During the procedure, the hands of 50% of patients became warm and dry in group Tb and only 40% remained so till 12 months, whereas in group Th, the hands of 100% of the patients became warm and dry during the procedure till 12 months. Conclusion Thermocoagulation of upper thoracic sympathetic chain on the head and neck of the second and third ribs is more effective than attacking the chain on vertebral bodies in patients with primary hyperhidrosis with no recorded complications.
