Within the last 20 years, the use of local injection with botulinum toxin has proven to be effective in the treatment of increased tonicity in both skeletal and smooth muscle as well as in illnesses presenting with increased secretion from glands. Following local injection, the botulinum toxin reduces muscle tone effectively for several months and also reduces secretion from sweat, lachrymal, and salivary glands. Botulinum toxin has influenced therapy in neurology like no other substance, and it is now considered the drug of choice for treatment of cervical dystonia, blepharospasm, and hemifacial spasm. Proper application of the drug is, however, a prerequisite for success. This comprehensive atlas presents all of the information necessary for its use, including dosage, muscle action, localization, and injection technique. Designed for quick navigation, it presents detailed visual demonstrations of the treatment of 126 different muscles organized by body region, illustrating muscle action, injection sites, injection protocols, and injection techniques for each muscle. Written by a doctor with many years of experience using botulinum toxin, this unique book is ideal for clinicians seeking to incorporate this therapy into their practice and is intended for all specialists, including neurologists, dermatologists, pediatricians, ophthalmologists, and others who use this drug.
