Local flaps are the procedure of choice in reconstruction of skin defects of the face if the donor defect is minimal. The sliding V-Y subcutaneous island flap is gaining in popularity but has been primarily used in dorsal defects of the nose. Patients demonstrating its application in nostril defects are presented. Indications for the use of this flap continue to expand.
Three patients underwent rhytidoplasty in an office surgical facility under dual ceiling-mounted lights. Each patient incurred a third-degree burn on the left cheek. A particular combination of a specific defective light fixture and bulb appeared to be the causative factor. The risk of burning human tissue is enhanced when epinephrine is injected for vasoconstriction and the tissue is undermined. In addition, focusing dual lights on the surgical field increases the radiant energy delivered. The maximum radiant energy safe for human tissue should not exceed 25 mW/cm2.
A case of chronic subluxation of the digital extensor tendon is reported, and a new surgical technique for repair is described. A partial-thickness trapdoor three-sided flap is made out of the dorsal joint capsule, brought through an incision in the ulnar sagittal band, and sutured back down. This centers the tendon and creates a new, stable tunnel through which it may glide.
Juvenile aponeurotic fibroma is a rare benign tumor found primarily in the extremities of children and young adults. Clinically, it presents as a painless, mobile solitary mass in the hand. It may represent the cartilage analog of fibromatosis. Since it has a distinct tendency toward local recurrence, wide excision without sacrifice of function is the indicated treatment. Two cases are presented illustrating the diagnostic features and treatment of this disease process.
