RESUMEN
Scars can cause aesthetic or functional disturbance. Several interventions had been described to improve their appearance. We propose that the combination of some of those treatments can synergize their effects on the scar. We designed a prospective pilot study with ten patients using the patient as their own control to compare different interventions. In each patient, the scar was divided into four parts treated differently: 1. No treatment (control), 2. Fat grafting only, 3. Fat grafting and Hyaluronic Acid (HA), 4. Fat grafting, HA and with a non-fractional laser. Each part of the scar was evaluated by the Patient and Observer Scar Assessment Scale (POSAS). Treatment of the scar with the combination of the three modalities showed better results in the observer scale. In addition, a combination of fat injection, HA, and subsequent skin resurfacing with non-ablative laser showed better outcomes for all parameters on the Observer Scale except vascularity, while on the Patient Scale thickness, relief, pliability, surface area, and overall measurement were better. The combination of all three treatments tends to improve scarring results and appears to be safe and effective. However, further studies with larger samples are needed to explore the potential use of this combined treatment.
RESUMEN
AIMS: To report our experience and results in BRAVA breast pretreatment for full breast reconstruction by autologous fat grafting. BACKGROUND: BRAVA (bra like vacuum-based external tissue expander) is a method developed to expand the skin envelope, thus creating more space for the fat graft for breast reconstruction. METHODS: Since 2015 we began to perform a full breast reconstruction by BRAVA and autologous fat grafting. This is a multiprocedure breast reconstruction that includes pretreatment by using the BRAVA device for 180 hours before each surgery. We will focus on the number of procedures and time duration that was needed to complete the breast reconstruction the aesthetic results and the complication rates. RESULTS: Between the years 2015-2019 we preformed 13 late full breast reconstructions using the BRAVA. Six women were post-radiotherapy and they completed their breast reconstruction after 5.7±1.3 rounds during 20.3± 5.3 months. Non-irradiated patients completed their breast reconstruction after 2.7±0.5 rounds during 9.4±2.6 months. We grafted an average volume of 218±16.7 ml of fat per surgery. This was in comparison to an average of 100ml fat volume grafted in surgery without pre-expansion according to the literature. We had no complications and the aesthetic results were satisficing. CONCLUSIONS: The addition of BRAVA expansion procedure before autologous fat grafting leads to a larger volume of fat that can be injected in every operation and reduction of procedures. The procedure is safe and with good aesthetic results.

BACKGROUND: Tissue expander is a major reconstructive modality. Its main disadvantages include: long and inconvenient period of inflation with temporary deformity of the surrounding tissue. Osmotic expander was developed in order to eliminate some of these limitations. It is a self-filling device which absorbs fluids in order to achieve tissue expansion faster. PURPOSE: We present our experience with 28 consecutive cases of tissue reconstruction using osmotic expanders. We wish to emphasize the main advantages and limitations of this device. METHODS: The present study was launched in May 2008, until April 2014, for twenty eight patients, median age 26 years with reconstructions using an osmotic expander (total of 35 expanders). The reasons for using tissue expander included large congenital nevi (75%) and scars. RESULTS: In all of the cases, the operative and post-operative management was uneventful. During the expansion period, there were 2 outpatient clinical visits. The average expansion time was 9 weeks. In 11% (three patients) there was partial extrusion of the expander. In all other cases there were no complications and the final aesthetic results were satisfying. DISCUSSION: Osmotic expander is an advanced modality for tissue reconstruction. The final shape and size are precisely predictable. Its initial small size allows for a small surgical incision and short overall operating time. The expansion period is shorter and more convenient for the patient. Its main disadvantage includes the inability to control the filling rate and the need to remove the expander in case of damage to the overlying tissue. CONCLUSION: Osmotic expander is a reliable tool for tissue expansion. It allows for a satisfying aesthetic result in a shorter period of time and with less inconvenience to the patient.
