When performing hair transplantation procedures, it is of the foremost importance to try to obtain the maximum survival rate possible of transplanted micrografts. We present an in-vitro model to test hair graft survival and growth after various surgical procedures. Material and Methods: A total of 1020 human anagen hair follicles was obtained from 50 male patients and thus randomly assigned to one of the following groups: Group A (control), conventional micrografts cultured as dissected; Group B (experimental), conventional micrografts preserved (before culture) for five hours in a storage medium; Group C (control;), conventional micrografts preserved (before culture) for five hours in saline at room temperature; Group D (experimental), conventional micrografts preserved (before culture) for 5 hours at1°C; Group E (experimental), “plucked” hair follicles; Group F (experimental), follicular units; Group G (experimental) skeletonized micrografts. Hair follicles from all the groups were then cultured for 10 days. Results: A statistically significant difference was found between the survival rate of follicles from Group B (98%) and Group A (87%), as well as between the growth rate of Group E (mean 10-day shaft growth =2.36 mm) and Group F (mean 10-day shaft growth =2.23 mm) as compared to Group A. No statistically significant differences were found between the growth rate of follicles from Group C and Group D or from Group G and Group A. Conclusion: According to our data, the described method is, in our opinion, an useful adjunct in order to quantitatively evaluate the effects of various procedures in the field of hair transplantation surgery.

Abstract

When performing hair transplantation procedures, it is of the foremost importance to try to obtain the maximum survival rate possible of transplanted micrografts. We present an in-vitro model to test hair graft survival and growth after various surgical procedures. Material and Methods: A total of 1020 human anagen hair follicles was obtained from 50 male patients and thus randomly assigned to one of the following groups: Group A (control), conventional micrografts cultured as dissected; Group B (experimental), conventional micrografts preserved (before culture) for five hours in a storage medium; Group C (control;), conventional micrografts preserved (before culture) for five hours in saline at room temperature; Group D (experimental), conventional micrografts preserved (before culture) for 5 hours at1°C; Group E (experimental), “plucked” hair follicles; Group F (experimental), follicular units; Group G (experimental) skeletonized micrografts. Hair follicles from all the groups were then cultured for 10 days. Results: A statistically significant difference was found between the survival rate of follicles from Group B (98%) and Group A (87%), as well as between the growth rate of Group E (mean 10-day shaft growth =2.36 mm) and Group F (mean 10-day shaft growth =2.23 mm) as compared to Group A. No statistically significant differences were found between the growth rate of follicles from Group C and Group D or from Group G and Group A. Conclusion: According to our data, the described method is, in our opinion, an useful adjunct in order to quantitatively evaluate the effects of various procedures in the field of hair transplantation surgery.
