    Hilos de tracción de polidioxanona y toxina botulínica en el tratamiento de parálisis facial crónica: a propósito de 2 casos y revisión de la literatura
    (Universidad Internacional de La Rioja, 2020) Marta Amin; Diego Araya; Joaquín Navarro; Gladys Josefina Velazco Viloria; Víctor Mercado
    We report clinical cases of two patients who present chronic facial paralysis, with the anatomical, functional and self-perceived alterations that accompany this pathology. The sequelae present significantly affect self-esteem and impact the psychological condition of patients. A therapeutic alternative is proposed that associates the use of traction threads of Polydioxanone and Botulinum Toxin, tending to achieve, on the one hand, the elevation of the facial tissues fallen on the paralyzed side and, on the other hand, to decrease the contraction of the contralateral healthy musculature, thus allowing, reduce the existing facial asymmetry. We propose that such a procedure may constitute an interesting non-invasive therapeutic alternative, repeatable over time and that allows the functional and aesthetic sequelae present in those patients with long-lasting facial paralysis to be attenuated.

    Toxina botulínica a, una alternativa terapéutica en el manejo del dolor en patologías de cabeza y cuello
    (Universidad Internacional de La Rioja, 2020) Diego Araya; Marta Amin; Joaquín Navarro; Gladys Josefina Velazco Viloria; Víctor Mercado
    Botulinum toxin has been widely used in different areas since the 1970s. The aesthetic area is the most popular at the moment, but this same use allowed us to observe the potential it has in the management of painful conditions such as migraines, neuropathic pain, fibrosis, neuralgia, even pain after chemotherapy or radiotherapy treatment after suffering from head and/or neck cancer. This article reviews the mechanism in which botulinum toxin works and the postulates on how it has an analgesic effect and its potential for different pathologies associated with head and neck pain.
