ObjectiveTo investigate the application effects of presuture shortening of orbicularis oculi muscle in blepharoplasty in the middle and old aged patients.

MethodsSixty middle and old aged patients with palpebral bags were randomly divided into the control group and observation group(30 cases each group).The control group was treated with traditional percutaneous lower eyelid blepharoplasty, and the observation group was treated with presuture shortening of orbicularis oculi muscle based on the traditional blepharoplasty.The orbicularis oculi muscle was separated, and the line perpendicular to the orbicularis oculi muscle at a distance of 0.5 cm from the outer canthal angle was designed, the orbicularis oculi muscle was cut off.The traction thread was sutured at the broken end, the one side broken end was sutured into the deep surface of the other end in advance, and the position of suture was adjusted according to the tension of orbicularis muscle.When the orbicularis muscle reached a better shape and tension, the patients were asked to open their eyes to the forehead for observing the effects of blepharoplasty.The overlapping part was excised, and the broken end was finely sutured.The curative effect between two schemes was compared and analyzed.

ResultsAfter 1 year of operation, the satisfaction degree in observation group was higher than that in control group(P < 0.01).There was no statistical significance in complications between two groups(P>0.05).

ConclusionsThe application of presuture shortening of orbicularis oculi muscle can significantly improve the treatment effect and satisfaction of patients, which is worthy of promotion.
