Abstract:
The production of sweat in the temporal skin region may be a serious problem for patients with hearing aids, active middle ear implants or cochlear implants. We report on two patients suffering from a loss of function of their hearing aid and a reduction of the "wear comfort" of an active middle ear implant. The patients underwent intracutaneous botulinum toxin (BTX) treatment of the temporal skin region. In both patients a distinct improvement of their complaints occurred, enabling them to use their hearing aids and active middle ear implants continuously. BTX injections are suited to improve sweat-caused complaints in patients with hearing aids, active middle ear implants and cochlear implants.
