Purpose
To compare the outcomes of two types of tarsoconjunctival pedicle flaps for reconstruction of large lower eyelid defects.
Methods
Retrospective medical record review of consecutive patients who underwent centrally-based or laterally-based tarsoconjunctival pedicle transconjunctival flap for lower eyelid reconstruction for defects greater than 50% of the lid margin. Full thickness skin grafts were used for anterior lamellar reconstruction in all cases. The primary outcome measure was eyelid position, function and satisfactory cosmesis.
Results
Forty-three patients were identified. Twenty-six patients underwent reconstruction with a centrally-based tarsoconjunctival pedicle flap; 17 patients underwent reconstruction with a laterally-based tarsoconjunctival pedicle flap. The average size of the lid defect was 77.7% (range 50-100%) in the central group and 75% (range 50-100%) in the lateral group (p=0.604). Mean follow up time was 61.5 weeks in the central group and 46.6 weeks in the lateral group (p=0.765). After division of the flap and during follow up, 27% of the centrally based group required revisional surgery with none in the laterally based group (p=0.03). 100% of the patients with centrally based flaps required second staged division of flap, whereas only 52% of patients with a laterally based flaps underwent second staged flap division. (p<0.001)
Conclusion
Outcome suggests that for reconstruction of large lower lid defects requiring lid sharing procedures, both centrally and lateral-based procedures have equivalent functional outcome. However, the laterally based group has less need for revisional procedures and may not need a second stage division of the flap.
