Capsular contracture in implant based breast reconstruction-the effect of porcine acellular dermal matrix

BACKGROUND Irradiation of implant-based breast reconstructions (BR) is known to increase capsular contracture (CC) rates on average by 4-fold over non-irradiated reconstructions. The use of acellular dermal matrix (ADM) has been associated with lower CC rates in non-irradiated reconstructions (0-3%). Experimental and clinical studies suggest that ADM may also reduce CC rates in irradiated breasts. The aim of this study was to evaluate CC rates in non-irradiated and irradiated one- and two-stage BRs performed with the assistance of porcine ADM (PADM). METHODS A single centre, retrospective, cohort study was designed from December 2008 to October 2012. A total of 200 immediate implant-based BRs were performed using PADM for inferior pole reinforcement. We included non-irradiated BR with a minimum follow up of 6 month from primary surgery (one stage) or from explantation of expander and implantation of the definitive implant (two stage). Of the postoperatively irradiated BR we included patients with 1 year or more follow up time from termination of radiotherapy. CC was graded using the conventional Spear-Baker classification and modified version for irradiated BR. According to the literature Grade III and IV CC were defined as clinically significant CC. RESULTS Of 200 BRs with PADM, 122 were included in this study (84 non-irradiated and 38 irradiated). Sixty-five BR were one stage and 57 were two stage BR. Grade III/IV CC was remarkable low in non-irradiated (6%) and irradiated BR (13%). There was a non-significant trend to increased Grade III and IV CC in irradiated BR vs. non-irradiated BR (13% vs. 6%, P=0.216). In this study follow up time (P<0.001) and the stage of ADM reconstruction (two vs. one stage, P=0.022) were significant risk factors for occurrence of grade III/IV CC on univariate analysis and remained significant for the follow up time (P=0.013) and remarkable for the stages (P=0.093) in multivariate analysis. CONCLUSIONS Our data support the current clinical evidence that ADM use in implant-based BR is associated with a reduced risk of CC when compared to the standard submuscular techniques in literature. The reduced risk is maintained in the setting of radiotherapy. Two stage procedures in our study population showed increased grade III/IV CC compared to one stage procedures with or without exposure to radiation

Protocol for the prevention and management of complications related to ADM implant-based breast reconstructions

Acellular dermal matrix (ADM) implant-based reconstructions have transformed direct-to-implant breast reconstruction (DTI). But like all surgery, it is not deplete of complications such as seroma, infections and wound healing problems. These are cited with varying frequencies in the literature. With increased experience and through a series of measures instituted to minimize complications, we have been able to improve outcomes for our patients. We report our technical refinements for prevention of ADM reconstruction associated complications including patient selection, implant selection, drains, dressing and our post operative antibiotic regime. We also outline our protocol for the management of ADM associated complications including seroma, simple and complex infection and red breast syndrome, such that the sequelae of complications are minimized and patients achieve a better long-term outcome

Ethnicity and Nonsurgical Rhinoplasty

Abstract Background Nonsurgical rhinoplasty is a procedure that is gaining popularity in aesthetic clinics particularly because of its minimally invasive nature compared with surgery. It is recognized that there are ethnic variations in nose injection techniques and planned aesthetic outcomes. Objectives The objective of this study was to explore experts’ views about the ethnic differences in the anatomical features of the nose and procedure-related considerations in nonsurgical rhinoplasty. Methods Using a priori set topics and questions, 4 expert aesthetic physicians, from 4 different ethnic backgrounds and working in 4 different regions, were asked to describe the essential elements to be considered when planning a nonsurgical rhinoplasty, including product choice, injection technique, safety measures, and any practical hints to facilitate achieving the desired outcome. Results All invited experts responded to the full set of questions. There were similarities between the treating physicians in some of the technical steps. Nevertheless, there were several differences identified regarding baseline anatomy and patient expectations that could be attributed to ethnicity. Patients’ and physicians’ expectations regarding a successful nonsurgical rhinoplasty can vary depending on their ethnic backgrounds. Therefore, with the current global ethnic and cultural diversities, in addition to the knowledge of the nasal anatomy and safe injection techniques, it is imperative that aesthetic practitioners have full awareness and a good understanding of these ethnic variations. Conclusions Nonsurgical rhinoplasty is a highly demanded aesthetic procedure. Patients’ ethnic differences need to be carefully taken into consideration when discussing, planning, and performing nasal fillers injection. </jats:sec

An evaluation of resource utilisation of single stage porcine acellular dermal matrix assisted breast reconstruction:A comparative study

Objectives: To evaluate resource utilization of single stage porcine acellular dermal matrix (ADM) assisted breast reconstruction compared with tissue expander (TE), latissimus dorsi flap and implant (LD/I) and latissimus dorsi flap and TE (LD/TE) reconstructive techniques.Materials and methods: Clinical data was collected for length of stay, operative time, additional hospitalisations and operative procedures, and outpatient appointments for 101 patients undergoing unilateral implant based breast reconstruction. Resources utilised by ADM (Strattice Reconstructive Tissue Matrix T) patients were analysed and compared to the resource usage of traditional techniques.Results: 25 patients undergoing single stage ADM (ADM/I) were compared with 27 having TE, 32 having LD/I and 17 having LD/TE reconstructions. Follow up was 24 months. Compared to TE, ADM/I had similar length of stay and operative time, lower rate and number of additional procedures, fewer, shorter re-admissions (p &lt;0.05) and fewer appointments (p &lt;0.05). Compared to LD/TE, ADM/I had shorter length of stay and operative time (p &lt;0.05), lower rate and number of additional procedures, fewer, shorter re-admissions (p &lt;0.05) and fewer appointments (p &lt;0.05). Compared to LD/I, ADM/I had shorter length of stay (p &lt;0.05) and operative time (p &lt;0.05), fewer appointments, similar rate and number of additional procedures but required more and longer re-admissions.Conclusion: In our experience, unilateral single stage ADM/I was associated with fewer resources utilised in comparison with two staged TE and LD/TE reconstructions in both complication-free and complicated settings over a 24-month period, despite requiring aesthetic revision in 60.9% of patients. Compared to LD/I, resource utilisation was commensurate in complication-free and complicated settings.</p
