Background There are several local complications associated with subcutaneous injection of illicit polymers, including: injection-site deformity, granulomas, and skin changes. Objectives To compare the postoperative complications and symptom flare in patients undergoing surgical excision of foreign-body granulomas. Methods We retrospectively examined data of patients who underwent surgical removal of foreign-body granulomas caused by polymer injection for cosmetic purposes with UAL, en bloc excision with primary closure, skin grafts, or free flaps during 2014–2020. Data collected included demographic and operative parameters. Postoperative complications, symptom flare, and time to flare were reported. Relationship between type of surgery and complications, symptom flare, and time to flare was determined through statistical analysis. Results The final cohort included 49 surgeries (42 primary and 7 secondary) in 35 patients. Overall complication rate was 28.9%, with no significant intergroup differences (30.8%, 20%, 66.7%, and 40%; p = 0.328). Wound dehiscence and skin burns were the main complications. An overall symptom flare of 35.1% in surgical treated areas over a mean period of 28.49 months was reported. Chi-squared test indicated statistical significance between type of surgery and symptom flare (p = 0.004) and between complications and flare (p = 0.013). Kaplan–Meier test for flare was statistically significant (p = 0.006) after comparison of the four groups. Conclusions Rate of postoperative complications was similar for each type of surgery. However, en bloc excision and reconstruction by either primary closure or free flap was associated with a significantly decreased rate of symptom flare and a longer symptom-free period.
El conocimiento preciso de los patrones vasculares permite mejorar los resultados de la reconstrucción regional del pabellón auricular y el diseño de colgajos regionales dependientes de la arteria temporal superficial para la reconstrucción facial. En México, no contamos en la actualidad con descripciones anatómicas de las variantes vasculares normales de la arteria temporal superficial. El objetivo de este trabajo es la descripción de las variantes anatómicas de la arteria temporal superficial a través de la disección de este vaso en 12 regiones tempo-parieto-occipitales en cadáveres. Nuestros resultados muestran que la arteria temporal superficial siempre se divide en dos ramas, una anterior y otra posterior, la distribución de ésta se sitúa en el cuarto más posterior de la región temporal, con una bifurcación alta. La distribución de la anatomía vascular, tomando en cuenta el calibre mayor de la arteria temporal superficial con respecto a la arteria auricular posterior, la ausencia de esta última en 4 de las regiones estudiadas, así como la distancia de dichos vasos con respecto al conducto auditivo externo, sugieren que en nuestra población la irrigación del pabellón auricular depende de la arteria temporal superficial, restándole importancia a la aportación del riego sanguíneo de esta región por parte de la arteria auricular posterior. Nuestro estudio arroja resultados que indican la existencia de variaciones importantes en la anatomía vascular regional que justifican la realización de estudios posteriores que permitan una descripción mas detallada de la misma para aumentar el éxito de las intervenciones quirúrgicas.
