Combined hard palate spacer graft, midface suspension, and lateral canthoplasty for lower eyelid retraction: a tripartite approach.

Background: Eyelid retraction is an unfortunate consequence of cosmetic surgery, trauma, and disease states. It is frequently symptomatic and may be associated with dry eye syndrome and corneal compromise. The pathophysiology of lower eyelid retraction usually involves some degree of lateral canthal tendon laxity, middle lamella scarring, and malar descent.

Botox and collagen for glabellar furrows: advantages of combination therapy.

Plastic surgeons frequently administer botulinum toxin A (Botox) or collagen as monotherapy to treat glabellar furrows. This study evaluates the possible advantages of combination therapy. Sixty-five patients with moderate to severe glabellar rhytids were prospectively randomized to receive standard injections of Botox, Zyderm II collagen, or a combination.

COX-2 up-regulation in idiopathic carpal tunnel syndrome.

The objective of this study was to determine whether cyclooxygenase-2 (COX-2) is up-regulated in the synovium of patients with carpal tunnel syndrome. Twenty patients were enrolled: 16 consecutive patients with carpal tunnel syndrome and four control patients (exploration for non-carpal tunnel syndrome-related wrist or forearm pathology). Clinical data (demographics, pertinent history, symptomatology) were obtained preoperatively.
