ABSTRACT
La notalgia parestésica es una mononeuropatía sensitiva por atrapamiento localizada a nivel dorsal. Clínicamente se caracteriza por la presencia de prurito, parestesias y/o hiperalgesia asociados a placas hiperpigmentadas en el dermatoma correspondiente, que genera un gran impacto en la calidad de vida del paciente. Presentamos dos pacientes de entre 35 y 65 años con sintomatología crónica tratados en nuestro servicio mediante infiltraciones subcutáneas de toxina botulínica tipo A en las áreas afectadas. Observamos una disminución de la escala EVA de dolor y de la intensidad del prurito tras la infiltración, así como una disminución de la placa hiperpigmentada al mes, a los tres y a los seis meses y que se mantiene al año. Concluimos que el tratamiento con toxina botulínica tipo A podría ser una alternativa segura y útil en estos pacientes, ya que en nuestro estudio ha demostrado ser eficaz a más largo plazo que los tratamientos disponibles hasta la actualidad, aunque se necesitan más estudios con pacientes para confirmarlo
Notalgia paresthetica is a sensory mononeuropathy caused by compression localized in the dorsal region. The condition is clinically characterised by the presence of pruritus, paresthesias and hyperalgesia associated with a hyperpigmented patch in the correspondingt dermatoma, substantially impairing quality of life. We report the cases of two patients aged between 35 and 65 years with chronic symptoms and treated in our service with botulinum toxin type A in the affected areas. We observed a decrease in the EVA pain scale and the intensity of the pruritus after infiltrations, as well as a reduction in the hyperpigmented patch at the first, third and sixth months after the intradermal injections that has been maintained after a year. We conclude that botulinum toxin type A treatment could be a safe and useful alternative in these patients, as it has been shown to be effective over a longer term than available treatments to date, although further studies are required to confirm our findings
