- What are the aspect ratios of the pen tips used when opening a channel in hair transplantation?
- How much space does it cover in mm2?
- Comparison of Sapphire Fue Technique and DHI Technique
From time to time such questions come from patients. An important issue that our patients do not know is the area occupied by the canal on the skin.
|Nib||Sapphire FUE PEN||DHI CHOI-PEN|
|Pen width||1,5 mm||0,74mm – 1,14 mm|
|Pen length||5 mm||5 mm|
|Thickness of pen||0,1 mm||0,74mm – 1,14 mm|
|Area||1,5×0,1= 0,15 mm2||0,74×0,74= 0,54 mm2 *|
As can be seen in the table, the channels opened by sapphire fue technique are smaller in area. For us, the less space on the skin, the faster it improves.
