RESUMEN
Background: Eyebrows play an important role in protecting the eyes, and also transmit facial expression. Restoration of eyebrow loss after deep thermal burns is a challenging task because a scarred recipient area may affect the success rate of the hair transplantation outcome. Trials to improve this outcome via preparation of pretransplantation recipient area are mandatory. Methodology: Seventeen patients (20 eyebrows) with partial or total postburn eyebrow loss were recruited. Nanofat injection was done as a preparatory step before hair transplantation. Patients were followed up monthly for 6 months after follicular unit extraction. The outcome was assessed both objectively by phototrichoscopy and patient satisfaction, and by incidence of complications. Results: The mean eyebrow density of the recipient side was found to be 88.60â ±â 29.96 hair follicle per cm2, compared with 133.95â ±â 38.38 on the control side. The mean eyebrow thickness of the recipient side was found to be 0.07â ±â 0.01 mm, compared with 0.06â ±â 0.01 on the control side, The overall satisfaction was 60% regarding the density, 80% regarding direction, and 65% regarding symmetry. However, when it comes to texture, 45% were satisfied. Conclusions: Restoration of eyebrow loss after deep facial burn is a challenging procedure. Improving the recipient area before hair transplantation is recommended to achieve a satisfactory outcome. Waiting until maturation of the scarred tissue of the recipient area and preparation of it with nanofat can achieve a satisfactory outcome.
RESUMEN
Background: Liposuction is one of the most common procedures in the practice of plastic surgery. Since it evolved, continuous modifications have been to decrease blood loss so that patients are hemodynamically stable intra- and postoperatively. Tranexamic acid (TXA) has long been used for its antifibrinolytic properties that were beneficial in reducing blood loss, rate of transfusion, and hemoglobin drop in major trauma and surgeries. Its use in plastic surgery, however, is still limited. In this study, we aim to illustrate the effect of intravenous (IV) and local infiltration of TXA on blood loss in liposuction surgery. Methods: Between April 2019 and April 2021, 90 patients who requested liposuction for various body parts were randomly allocated into 3 equal groups: control group, IV TXA, and local infiltration of TXA. A sample was taken from infranatant and sent for hematocrit calculation. Volume of blood in lipoaspirate was then calculated. Patients were assessed for blood loss and postoperative bruising. Results: Volume of blood loss in lipoaspirate was considerably lower in the TXA groups, with 60% decrease in blood loss for the local TXA group in comparison with the control group. TXA has also been shown to markedly decrease bruising tendency in postoperative liposuction patients. Conclusions: TXA can be used to decrease blood loss in large-volume liposuction, modify the need for blood transfusion intra- and postoperative, and improve the results of liposuction procedure without the need for multiple sessions. Level of evidence: Level II, Risk/Prognostic Study.
