We present two patients who, after using Hyaluronic Acid (HA) in rhinomodelation procedures, present a non-ophthalmological vascular complication. We will analyze the clinical behavior of both patients and therapeutic management aimed at reversing this complication, as well as the current evidence regarding the facial anatomical areas of risk regarding the use of "Filler" and how to minimize adverse events. It is important to emphasize the progressive increase in the use of non-invasive techniques in facial harmonization, where HA mainly stands out and in the same proportion the incidence of vascular complications.
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

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.
Regenerative Synergy in Facial Rejuvenation: A Pilot Clinical Study of Polydioxanone Microspheres (Ultra V® UltraCol 200), Organic Silicon, and Adipostructuring

Background Dermal fillers used with minimally invasive techniques have currently achieved an important role in regenerative medicine and in alleviating skin damage over the years. Objectives To evaluate clinical results after the use of the Polydioxanone Collagen Biostimulator Ultra V® UltraCol 200 (Ultracol), commonly referred to as PDO microspheres, with the addition of organic silicon to enhance Ultracol biostimulation, using the adipostructuring technique in a group of older patients who consulted to improve the quality of their skin. Materials and methods The study included 20 patients (3 men and 17 women), aged 40 to 80 years. We used Ultracol plus organic silicon. Injections were performed using the facial adipostructuring technique, with a 22-gauge, 50-mm cannula, injecting 2.5 mL per hemiface in a single session. We evaluated results at 10 days and 2 months after the procedure using photography and parameters selected by a blinded evaluator, along with a satisfaction survey. Results Clinical evaluation demonstrated noticeable improvement in facial tridimensionality, with enhanced volumetric projection and contour definition. A reduction in nasolabial fold depth was observed, along with improved vertical positioning of the malar region. Additionally, better definition of the infraorbital area was noted, accompanied by a subtle increase in supraperiosteal volume. Overall, these changes were considered favorable outcomes in this treated older patient group. Conclusion Ultracol plus organic silicon, using the facial adipostructuring technique in a group of older patients, can be considered a suitable and safe therapeutic alternative.
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.
