Reconstruction of Extensive Periorbital Defects With Pericranial Flap.

Wide excision of recurrent malignant tumors of periorbital region leaves deep and large composite defects, requiring a reconstruction to restore both the form and function of the eyelids. In this study, a pericranial flap was utilized in the reconstruction of large, complex defects of periorbital region.This study included 5 patients who underwent wide excision of recurrent large medial canthus and supraorbital rim malignant tumors. All defects involved the medial parts of eyelids including medial canthal ligaments, nasal walls, periosteum, and medial orbital walls. Defects were reconstructed via a pericranial flap, which was facilitated by the natural concavity and the acute angled nature of the medial canthus.The pericranial flap is not only a versatile alternative to the local or regional flaps in the reconstruction of periorbital defects, but also has the advantages of availability of abundant amount of flap tissue.
