Reconstruction of Extensive Periorbital Defects With Pericranial Flap.

ABSTRACT: 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.

A Rare Cause for Recurrent Implant-Related Inflammation of Orbit: Dacryocystitis.

Ultra-thin porous polyethylene has been widely preferred in orbital blow out fracture repair for many years as a safe and stable material. Delayed complications related to the implant in orbital blow out fracture repair are very rare and usually begin as a periorbital inflammation. Infections and tissue reaction to the foreign body are regarded as main causes for implant-related inflammation of which symptoms may vary among the patients and may involve subacute and chronic eyelid swelling, skin redness, pain, conjunctival injection, proptosis, and acute orbital inflammation.Presented here is a patient of recurrent periorbital inflammation who underwent orbital floor repair with ultra-thin porous polyethylene sheet which was complicated by dacryocystitis in the late follow-up period.
