Purpose

Medial canthal fistula in the context of destructive processes poses a significant surgical challenge. We report closure of the fistula using a novel Back-to-Back Sandwich Flap (B2BSF) in two patients, one with cocaine-induced midline destructive lesions (CIMDL) and the other with fistula secondary to radiotherapy for SCC and DCR surgery.


Methods

The surgery involves fashioning a paired inner layer inverted local skin flap covered by an outer layer skin glabellar to create a double layer back to back flap.to cover the defect. It was used to close a 2.5 by 2.5 mm fistula in one patient with CIMDL and a 0.5 by 1 mm in a second patient with radiotherapy damage post-SCC.


Results

Three months post-surgery, the fistula remained closed in both patients.


Conclusion

Medial canthal fistula can compromise the ocular surface and vision and is unsightly and uncomfortable. It is difficult to close the fistula, particularly in a destructive process with unhealthy and avascular surrounding tissue. The B2BSF appears to be an effective surgical reconstructive strategy for this challenging situation.
