Aims:
The lateral orbital orbicularis propeller flap (LOOP) is a propeller flap raised on a non-axial orbicularis oculi pedicle. Once mastered, it is speedy to raise, extremely reliable, and capable of transposing thin, supple, and relatively hairless skin and subcutis from the temple region to the periocular region. We aim to present our experience in using the LOOP flap for the reconstruction of a range of periocular defects.

Method:
Retrospective review utilising our Mohs database, electronic records, and image library.

Results:
A total of 44 reconstructions were performed. Of the 39 lower lid defects, 22 were full-thickness (bilamellar). Posterior lamella reconstructions in these 22 cases were free tarsoconjunctival graft (20), conchal cartilage with perichondrium (1), and Hewes flap (1). A total of 13 reconstructions of the 22 were total or near-total lid reconstructions. A further 17 patients had anterior lamella defects alone, of which 3 amounted to resurfacing the entire lid. However, 5 patients underwent upper lid reconstruction, 2 of which were 50% lid, 2 required a free tarsal graft, and 1 conchal cartilage graft with buccal mucosa. There were no instances of necrosis of either the flap or the posterior lamella grafts. There were 7 minor complications.

Conclusions: In our unit, the LOOP flap has become the reconstruction of choice for laterally based, transversely extensive defects of upper lid, lower lid, and malar areas. Its reliability, relative simplicity, and excellent cosmetic and functional outcomes merit much wider utilisation amongst the plastic and ophthalmic surgery community.
