A single- versus double-layered closure technique for full-thickness lower eyelid defects: a comparative study

Area of Science:

• Ophthalmology
• Plastic Surgery

Background:

• Lower eyelid reconstruction is crucial after tumor excision.
• Standard techniques often involve multiple layers of closure.
• Evaluating simplified closure methods can improve surgical efficiency.

Purpose of the Study:

• To compare single-layer versus double-layer closure for lower eyelid defects.
• To assess the safety and efficacy of a simplified closure technique.
• To evaluate complication rates in lower eyelid reconstruction.

Main Methods:

• Retrospective case-control study of 188 eyelids (2011-2014).
• Group A: single-layer closure with non-absorbable sutures.
• Group B: double-layer closure with absorbable sutures.

Main Results:

• No significant difference in notching between groups (p = 0.96).
• No wound dehiscence occurred in either group.
• Slightly higher, though not statistically significant, rates of subcutaneous granuloma and mild redness in the double-layer group.

Conclusions:

• Both single- and double-layered techniques are safe and effective.
• Simplified single-layer closure offers a viable alternative.
• Eyelid margin adjustment sutures are rarely needed with either method.
