of the palms between sexes associated with diverse occupational conditions or hobbies could probably contribute to the development of MW. Muscle weakness was observed in muscles close to the injection site. This indicated that the spread of BTX-A impaired neuromuscular transmission in the intrinsic muscles of the hand, but it did not affect proximal forearm muscles used for handgrip movements.
Our study shows that 75U-100U per palm of BTX-A-injected intradermally drastically reduced sweat secretions in patients with hyperhidrosis. In order to decrease the possible complications, we suggest that the physicians should be well trained in the subcutaneous or intradermal injection technique and different foci of hyperhidrosis should be treated in separate sessions. In addition, we recommend that low dosages of BTX-A be used per injection site and that the number of sites to be injected be determined according to hand size.

Conclusion

BTX-A remains a reliable therapeutic method-for focal palmar hyperhidrosis.-Local side effects such as MW do not seem to be a restrictive factor, probably due to their mild and-transient nature.
