Effects of endoscopic forehead/midface-lift on lower eyelid tension.

Objective: To evaluate and quantify the increase in lower eyelid tension (stress) after endoscopic forehead/midface-lift in a cohort of patients with normal lower eyelid function preoperatively.

Methods: A prospective nonrandomized study was conducted at a private facial plastic surgery practice and ambulatory surgical center on 22 patients who underwent subperiosteal endoscopic forehead/midface-lift from October 2000 to June 2002. Patients were evaluated preoperatively, 4 to 6 months postoperatively, and approximately 12 months postoperatively.

Reconstruction after resection of sphenoid wing meningiomas.

Objective: To review our experience of reconstructing the lateral and superior orbital walls after resection of sphenoid wing meningiomas. We will review the presentation and complications, examine the aesthetic results postoperatively, and compare preoperative and postoperative computed tomographic scans. To our knowledge, a comparative analysis of preoperative defect and postoperative reconstruction has not been performed.

Surgical management of concavities of the distal nose.

Normal topographic anatomy of the distal nose is a reflection of the delicate integration between the lower lateral cartilage, the upper lateral cartilage, the sep-tum, and skin. Understanding these relationships will help the rhinoplasty surgeon diagnose and treat con-cavities of the distal nose. Most patients present with a hybrid of these defects.

Expression of urokinase-type plasminogen activator and its receptor in keloids.

Background: The urokinase-mediated plasminogen activation (uPA) system plays a central role in a number of cellular processes including tissue remodeling, cell migration, and angiogenesis. Elevated uPA activity has also been seen with tumor invasion and metastasis in a variety of malignancies. Keloids represent an aberrant form of wound healing characterized by uncontrolled growth with invasion beyond the margins of the original wound.
