Follicle trauma and the role of the dissecting microscope in hair transplantation. A multicenter study.

Use of the dissecting stereomicroscope during hair transplant graft dissection has been advocated as a means of reducing hair follicle transection and improving graft growth. The study evaluated the prevalence of hair follicle transection in grafts prepared with and without the dissecting stereomicroscope. Approximately half as much transection (10% vs 20%, p < 0.05) was noted in grafts prepared with microscopes, suggesting their use may be associated with less hair follicle trauma and improved hair growth.
