Abstract

Background

The decision of surgical approach for hair restoration often involves evaluation of the type of alopecia; however, the impact of surgical hair restoration from existing techniques in specific population subsets has not been comprehensively investigated.

Objectives

The authors sought to systematically review the literature on micrografts, minigrafts, mini-micrografts, tissue grafts, tissue flaps and expanders, as well as evaluate graft survival and satisfaction within specific populations in a meta-analysis.

Methods

PubMed and Scopus literature searches between 1980 and 2018 yielded 57 articles for systematic review and 34 articles for meta-analysis. Study design, mean patient age and gender, patient alopecia type, surgical hair restoration technique, number of treatment areas, mean follow-up, graft survival rate and satisfaction rate were extracted from each study, and a meta-analysis was performed.

Results

The pooled rates of graft survival were 84.98% (95% CI 78.90–91.06) using micrografts and 93.11% (95% CI 91.93–94.29) using micrografts and minigrafts in nonscarring alopecia patients, as well as 88.66% (95% CI 80.12–97.20) using micrografts and 86.25% (95% CI 74.00–98.50) using micrografts and minigrafts in scarring alopecia patients. The pooled rates of satisfaction were 89.70% (95% CI 82.64–96.76) using micrografts and 97.00% (95% CI 92.48–100.0) using micrografts and minigrafts in nonscarring alopecia patients, as well as 97.80% (95% CI 94.59–100.0) using micrografts and 88.70% (95% CI 66.49–100.0) using micrografts and minigrafts in scarring alopecia patients. Dot plots depict rates of graft survival rate from micrografts and satisfaction from micrografts and minigrafts.

Conclusion

Surgical hair restoration for nonscarring and scarring alopecia yields high graft survival and satisfaction rates.
