I am only sharing my HT surgery experience as a patient.
Technical points should be explained by the experts on this website.
Personally i feel that , if the hair transplant is done on the frontal area (to create hair line etc), then swelling may be noticed on the forehead and may progress to eyes . Gravity effect may be reason of temporary progression of swelling to eyes level.
I think swelling on the receipt area is not related to the FUHT and FUE.
In one sentence swelling would be noticed more to people , if receipt area is frontal head , and would be unnoticed if receipt area is top head . But the swelling level may be related to the level of anesthesia and number of punching in receipt area. Different Receipt area (front head or top head )swelling only looks different , because of illusion to people.
Donor swelling is independent from HT receipt area. As i have gone multiple phase surgery from Dr. A’s Clinic , having experience of both FUTH and FUE, I could not identify the difference in swelling on donor and receipt area ,because swelling was negligible.
But i can give my one practical example, In multiple phase surgery , i had also gone beard hair transplant. I shaved my beard after 7 days of surgery and in Job , no one judged it. Reason is that ,at the time of surgery, my beard hair length was 3 mm approx , and doctors had taken my donor beard hair in diffuse pattern . Finally my red blood dots were camouflaged between 3 mm length beard hairs. Then after 7 days , i shaved.
Meaning is that , with in 7 days , FUE donor area red dots were healed up with out leaving a scar and i was able to shave my beard.
Still today , after shave , no one can judge or can point out any dot on my face.
With regards
