RESUMO
Background: Facial wounds are challenging for dermatologic surgeons, particularly traumatic facial wounds, because they can yield disfiguring scars. To obtain good results, narrow needles and sutures are needed. Hair filaments have a very small diameter (0.06-0.1 mm) and could serve as suture threads for facial wounds. Objective: To determine the aesthetic outcomes by using autologous hair to suture facial wounds. Patients and Methods: This case series study examined the aesthetic outcomes of all consecutive female patients with traumatic facial wounds who underwent autologous hair-based stitching in 2009-2016. Autologous hair ampoules were generated from an insulin needle. Micro instruments were used for wound stitching. Results: In total, 54 females (mean age, 10.8; range, 3-45) years had 56 traumatic wounds. Mean wound length was 3.6 (range, 1-12) cm. Injury depth varied from cutaneous-only to muscle involvement. Suturing yielded good edge coaptation, nice healing, and excellent aesthetic outcomes; the scars were often scarcely visible. Suture marks were not detected. Cutaneous reactions did not occur. Conclusion: Autologous hair can serve as a thread for closing facial wounds. It is low cost and thus suitable in settings characterized by facility and equipment limitations. It is also suitable for the battlefield.
RESUMO
Healing is a complex multifactorial process, hence it is not easy to be studied accurately. In this paper we tried to demonstrate the potentials of application of autologous blood by injection into the raw areas and ulcers of three diabetic patients using their blood as an alternative to synthesized and cultured stem cells or growth factors. It was found that a natural easily obtained blood can be used to enrich the media of the wound. Also it was applicable in relation to its cost-effectiveness as well as availability. The healing process was accelerated in the injected side more than the non-injected one.
