Microscopic Dissection (German Microscope)
At Medispa we use German microscope in every step of hair transplant. Microscopes used for obtaining a three-dimensional view of a specimen. (Stereoscopy is simultaneous vision with two eyes producing a unique vision in which the observer can perceive the relative distances of objects in space.)
• During Strip / FUE hair harvest we use 4x magnification which decreases the graft transaction rate to less .5%
• During dissection and graft division we use 10x magnification to decrease hair shaft damages and hair transaction to give maximum yield or re-growth rate.
• During implantation of the graft we use 4x magnification.
• At our center we see more than 95% hair re-growth rate i.e. if we plant 100 hair 95 hairs surely grows.
Working with binocular Stereo-microscopes, they carefully remove excess fibrous and fatty tissue while trying to avoid damage to the follicular cells that will be used for grafting. The latest method of closure is called ‘Trichophytic closure’ which results in much finer scars at the donor area.
Hair transplant surgeons place a high importance on the integrity of naturally occurring hair follicle units to find improved methods of hair graft harvesting, dissection, grading and transplantation. Studies have concluded that there is a measured increase in teh yield of follicular unit grafts and the total amount of hair harvested from the donor strips when technicians use dissecting microscopes as compared to magnifying loupes with trans-illumination. The studies also noted increases in quality and quantity in all aspects of the hair follicle dissection procedures. In addition, when complete microscope integration programs were studied, advantages were even more significant.
The increasing importance that hair transplant surgeons are placing on maintaining the integrity of the naturally occurring follicular unit, has generated great interest in finding the ideal method of graft dissection.
The present study attempts to compare two popular dissecting techniques; the dissecting microscope, and magnifying loops with transillumination, in the preparation of follicular unit grafts.
Donor strips from forty one patients were used in a prospective, bilateral controlled fashion to compare the two different dissecting techniques.
Microscopic dissection produced a 17% greater yield of hair as compared to magnifying loops with transillumination.
The results of this study show an increase in the yield of follicular unit grafts, as well as the total amount of hair harvested from the donor strip, when using the dissecting microscope as compared to magnifying loops with transillumination. This increase was observed when only the latter part of the dissecting procedure was studied. When complete microscopic dissection is used, the advantage should be even more significant.
