Implication

Clinical study reveals impaired perfusion from combined rotation and stretching in upper eyelid flaps, indicating strict tension limits during surgical flap transposition.

Key Points

To evaluate how flap length, physical stretching, and 90-degree rotation affect blood perfusion in human upper eyelid skin flaps.
Evaluated 29 upper eyelids during blepharoplasty procedures in patients, maintaining a 1-cm-wide proximal attachment to model a random pattern skin flap.
Quantified perfusion via laser speckle contrast imaging at baseline and under stretching forces of 0.5, 1, and 2 N, repeated following a 90° flap rotation.
Blood perfusion declined rapidly along flap length: 60% at 0.5 cm, 37% at 1.0 cm, and 22% at 2.0 cm from the base.
Stretching nonrotated flaps reduced perfusion at 0.5 cm to 43%, whereas 90° rotation alone produced no significant perfusion changes.
Combining 90° rotation with 2 N stretching force decreased perfusion at 0.5 cm from the base down to 22%.
