In six patients affected by congenital ptosis, a disposable epidural a
nesthesia needle was used instead of a Wright needle for frontalis sus
pension surgery. For each of the patients in this study, the use of a
disposable needle permitted smaller supra-brow are incisions with a mi
nimal scar. The needle also created a smaller breach in the plane of l
evator aponeurosis and preaponeuronic fat, causing less tissue edema a
nd bleeding than with a Wright needle.
