Uso da membrana autóloga rica em leucócitos e plaquetas em rinoplastia estruturada

Abstract

Introduction: Rhinoplasty is one of the most challenging procedures in plastic surgery because the surgical modifications should attend to the patient’s expectations, to the need for functional correction allied to aesthetics. Leukocytes and platelets rich fibrin is an autologous membrane with great potential for tissue repair. Objectives: The purpose of this study was to assess the use of this membrane, associated or not with cartilage micrograft (diced cartilage), as an alternative technique to the camouflage of nasal dorsum irregularities and filling, correction of irregularities of the dorsum, nose tip, soft triangle, and K zone, filling in of dead space and an improvement in the healing process in primary or secondary rhinoplasties. Methods: The membranes were obtained using centrifugation of the patient’s peripheric blood before the rhinoplasty. At the time of use, the membrane was removed from the tube, separated from the clot, and used to the camouflage and filling in cases operated due to various indications, 19 associated with cartilage micrograft, and four sole. The authors present the clinical and photographic impressions of the immediate and late postoperative period, as well as the patients’ impressions using a specific questionnaire. Results: No patient had immediate or late post-operatory complications. The use of the membrane was sufficient and satisfactory to the camouflage and filling in all cases. Conclusions: This membrane showed to be an excellent surgical alternative to the camouflage and filling in rhinoplasty. On the other hand, it is rich in factors that can improve and accelerate the regeneration of the tissue.
