Tissue thread grafting: nonincisional double-eyelid operation

Area of Science:

• Ophthalmology
• Plastic Surgery
• Regenerative Medicine

Background:

• Conventional double-eyelid surgeries often rely on synthetic sutures for levator insertion.
• These methods can sometimes lead to complications or unnatural aesthetic outcomes.
• There is a need for safer, more integrated fixation methods in blepharoplasty.

Purpose of the Study:

• To evaluate the efficacy and safety of using autogenous tissue threads for supratarsal fixation in double-eyelid surgery.
• To assess the incorporation and fixation of tissue grafts in creating a palpebral crease.
• To determine the complication rates associated with this novel technique.

Main Methods:

• Utilized autogenous tissue threads (temporal fascia, periumbilical tissues, capsulopalpebral fascia) and allogeneic human dermis for supratarsal fixation.
• Employed a novel Yeop's needle or modified 5-0 Vicryl suture for thread engagement.
• Performed 78 double-eyelid operations (53 primary, 22 secondary, 3 tertiary) using a nonincisional technique pattern.

Main Results:

• Tissue threads were maintained for an average of 9.3 days, demonstrating effective temporary fixation.
• No complications such as infection or granuloma were observed at the eyelid or donor sites.
• Successful fixation of the palpebral crease was achieved in all cases.

Conclusions:

• Autogenous tissue threads provide a safe and reliable method for supratarsal fixation in double-eyelid surgery.
• The technique facilitates scarless, natural-looking double-eyelid creation through safe tissue incorporation.
• This approach offers a promising alternative to conventional suture materials, minimizing adverse events.
