ABSTRACT
BACKGROUND: Tranexamic acid (TXA) use in surgical procedures due to its hemostatic effects has been gaining an increased interest. In plastic surgery, the effects of TXA have been studied intravenously (IV), and there have been some reports regarding local use. OBJECTIVES: A comparative study examining the combined effect of IV and local TXA was conducted. METHODS: A randomized double-blinded controlled trial was performed for patients undergoing breast reduction treatment with liposuction and resection following the power-assisted liposuction mammaplasty (PALM) technique. All patients received 5 mL IV of 0.5 g/5 mL TXA on induction. Before installation, one researcher prepared two solutions of 1 L normal saline: one with 5 mL of 0.5 g/5 mL TXA associated with epinephrine 1:100,000 and the other with only epinephrine 1:100,000. These were randomly infiltrated in either the left or right breast. Clinical dermal bleeding was assessed for both breasts after deepithelialization. The lipoaspirate from these breasts was then compared with each other. A postoperative evaluation at 24 hours was performed to compare the ecchymosis rate. RESULTS: Ratios of decanted volume to total lipoaspirate was measured in bottles and compared between breasts. There was a statistical difference (P = 0.0002) in the ratio of decanted to lipoaspirated volume when comparing the control group (ratio: 0.21) with the treatment group (0.13). Video analysis revealed decreased dermal bleeding in the TXA group and postoperative evaluation less ecchymosis. CONCLUSIONS: The combined use of IV and local TXA can help reducing blood loss in liposuction as measured by decantation in separate drain bottles and as assessed clinically preoperatively and postoperatively.
ABSTRACT
Trichoblastic carcinoma is a rare malignant hair follicle tumor. It resembles basal cell carcinoma clinically, but different studies emphasize on the importance of differentiating between these two cancers since they have different clinical course which may affect treatment options and follow up. Regardless of its aggressive behavior, no consensus is present for the treatment of trichoblastic carcinoma. We presented the third case of pinna trichoblastic carcinoma, which was surgically excised and followed up for two years post-surgery.
ABSTRACT
Neural tumors localized in jaw bone are relatively rare. This article presents a case of intraosseous neurofibroma of the mandible in a 37-year-old female patient. A review of clinical, radiographic, histological features and surgical management of the patient are discussed along with a review of the literature.
