In the temple area the non receded Temporal hairline start at outer canthal plane , an average 4 cm in front of the pretragal vertical line , the temporal hairline extend down and forward at 45 to 60 degree angle up to the vertical outer canthal line , to create temporal peak . Non receded temporal peak is an average 1.5 cm higher than the eyebrow. From temporal peak temporal hairline extend down and backward at 45 to 60 degree angle and continue with the sideburns. Temporal hairline also recedes in hair loss. Temporal hairline recedes backward in Class 2-4 hair loss. In Class 5 to 7 hair loss, temporal hairline also recedes downward from outer canthal plane and temporal peak is lost.
If donor area allows, restoring the temporal hair line compliment the frontal hair line and make a complete hair line restoration.
If the temporal hairline has dropped below the outer canthal level, as in class 5-7 hair loss. If the donor area allows, this lost temporal hairline can be restored.
Draw a vertical line just in front of ear, where this vertical line intersect the outer canthal plane, mark that point. Mark another point 2 cm in front of it. Connect the receded temporal hair line to this point. To restore the temporal peaks, first try to find the traces of temporal peak, and restore it. If there is no trace of temporal peak, mark the new temporal peak .The average height of temporal peak from Frankfort horizontal line is 4.5 cm or 1.5 cm above the eyebrow level. Mark outer canthal line. Draw another vertical line parallel to the outer canthal line 1.5 cm behind it. Draw a horizontal line parallel to frankfort line at an average 4.5 cm height , Where this line intersect the vertical line behind the outer canthal line mark this point , it's the apex of temporal peak . Drop the temporal hairline down and forward from the apex of fronto temporal angle at 45 degree to join the marked apex of temporal peak. From apex of temporal peak drop the temporal hairline down and backward at 45 degree angle to join the sideburns.
Once the marking is done, perpendicular sites at 10 degree angle are created in backward direction. Symmetrical irregularities are created just like the frontal hairline. Temporal hair line is restored by single hair follicular units.
Frontal and Temporal hair lines are restored independently and they meet at the outer canthal plane, the joining of these two hairlines at the outer canthal plane is called Apex of fronto temporal triangle.
Frontal hair line should not chase the receded temporal hair line, below the level of outer canthal plane, a common mistake, which should be avoided. Most common aesthetically bad hairlines can all together can be avoided, if the frontal hairline marking simply stays circumferentially horizontal along the lower transition zone of calvarium.
If donor area allows restoring both frontal and temporal hairline complement each other and provides the aesthetically great hair restoration.
Nice and most informative Blog.
