Background: Large randomized controlled trials that evaluate the effects of negative-pressure wound therapy with instillation of a topical solution and dwell time (NPWTi-d) are lacking. There is a need to synthesize existing data across multiple studies to provide a more precise estimate of the clinical effects of NPWTi-d. Methods: A systematic literature review and a meta-analysis of comparative studies were performed to determine the effects of NPWTi-d versus control therapy in the adjunctive management of complex wounds. Weighted standardized mean difference or odds ratios and 95% confidence intervals were calculated to pool study and control group results in each publication for analysis. Results: Thirteen studies comprising 720 patients were included in the analysis. Significantly fewer surgical debridements were performed in NPWTi-d patients versus control patients (P = 0.01). Wounds in the NPWTi-d group were ready for closure faster than control wounds (P = 0.03). The odds of reducing bacterial count from baseline in the NPWTi-d group was 4.4 times greater than control group wounds (P = 0.003), and percent reduction of bacterial count in NPWTi-d wounds was evident in all studies that captured that endpoint. There was a significantly shorter length of therapy in NPWTi-d patients versus control patients (P = 0.03). Wounds in NPWTi-d group were 2.39 times more likely to close than control group wounds (P = 0.01). Length of hospital stay was not significantly reduced for NPWTi-d patients compared with that for control patients (P = 0.06). Conclusion: Results of this meta-analysis show a positive effect with use of NPWTi-d in various wound types.

Craniofacial surgery continues to be a rapidly evolving field, due in part to interdisciplinary collaboration that has allowed for sharing of knowledge and methodologies, which has expanded greatly due to online journals and publications. The Journal of Craniofacial Surgery (JCS) is a highly regarded journal that has attracted attention for its mission to increase diversity and global representation in manuscript submissions and research publications. The purpose of this study is to provide an objective measurement of global participation in craniofacial research specifically as it pertains to the JCS. Through a bibliometric analysis, the country of origin of all articles published in the JCS from 2010 to 2019 was analyzed. In line with its mission, the JCS increased its overall production 1.9 times during the past decade and increased its global representation 1.6 times, as represented by the number of countries contributing (78). The journal produced 8147 articles with Turkey (1424), USA (1397), China (1178), South Korea (1023), and Italy (644) being the top producers. The highest represented states were Florida (156), New York (130), California (117), Massachusetts (112), and Pennsylvania (106). The Journal of Craniofacial Surgery has the greatest diversity of country representation of the major plastic and reconstructive journals compared. Overall the JCS has stayed true to its mission to foster craniofacial research and is a valuable resource for craniofacial surgeons across the world. This study provides an analysis of trends in global contributions to craniofacial research and highlights areas for further increasing global contributors to the field of craniofacial surgery.
