Is it possible to get very small alarplasty cut like 1 mm?

There are various approaches to alar narrowing. In cases where not much narrowing is needed, I sometimes use a "cinching" suture without any excisions at all. Also, there are just wedge excisions of the alar walls which reduce the flare but do not narrow the nostril base. And of course, there are minimal excisions, as well!

An ajar excision if one millimeter is possible but it is unlikely that it would create much of a difference. Usually around 3 mm is more like it

Alarplasty is certainly the surgery of millimeters. 1 mm is so small, I find it hard to believe that a 1 mm nostril reduction would lead to a visibly improved result. I hope this is helpful and thank you for asking this question. Sincerely, Dr Joseph

When I measure alarplasty incisions every mm counts. There are times I measure to 0.5mm changes as well. As surgeons we can do it well because we use magnification glasses called Loupes.

? is it possible to have a 1 mm alar plasty incision? Unfortunately this is not possible. An alar plasty involves removing a section of nostril that is usually 2 to 5 mm wide. The incision to do this is at least 1 cm long which is about 10 mm. 1 mm is about the size of a pinhead. There’s no way to remove any visibly significant amount of tissue with a 1 mm incision.
