After Otoplasty is it possible that the bandage is not on tight enough and is it a problem if it is not tight enough?

The role of bandages immediately after otoplasty is foremost to prevent accumulation of blood between the cartilage and the skin.The dressings need to apply just enough compression to serve this role. However, too much compression can blanch the skin of the ear and deprive it of its blood supply, causing an ulceration. Therefore, tighter is not better.  An additional role of the bandage is to support the new shape of the ear and also to prevent inadvertent bending of the ear (esp while sleeping). Hopr this helps

The purpose of the bandaging is to support the buried sutures and prevent you bending the ears back while sleeping. Tightness is not really an issue. However, too tight will lead to redness on the outside of the ears
