Perforator artery response to tissue expansion: An experimental study in rabbits.

Background: The reconstruction of defects is a major area of interest in plastic surgery. Tissues are expanded to extend the tissue surface area and to prepare more reliable perforator flaps.

Objectives: Because expanded perforator flaps have become more popular, the aim of this study is to determine the response of the perforator artery to tissue expansion.

The Effects of Maxillary Expansion on Late Alveolar Bone Grafting in Patients With Unilateral Cleft Lip and Palate.

Purpose: The purpose of this study was to answer the research question of whether maxillary expansion provides enough postgraft stimulation to decrease the volume loss of alveolar bone grafts in patients with cleft lip and palate (CLP) who missed the appropriate treatment time.

Materials And Methods: This study was designed as a prospective controlled clinical trial. Thirty patients in the permanent-dentition stage with unilateral CLP were divided into 2 groups: In group I (mean age, 19.

Assessing the effects of melatonin and N-acetylcysteine on the McFarlane flap using a rat model.

Objective: To determine the effects of N-acetylcysteine (NAC) and melatonin, alone and in combination, on McFarlane flap viability in a rat model.

Methods: Forty Wistar rats were divided into four groups and received daily intraperitoneal injections for one week before surgery: control (sham [n=10]); melatonin (n=10); NAC (n=10); and NAC+melatonin (n=10). One week after surgery, the experiment was terminated and photographs were taken for topographic studies.

Brachial artery protected by wrapped latissimus dorsi muscle flap in high voltage electrical injury.

High voltage electrical injury can disrupt the vascular system and lead to extremity amputations. It is important to protect main vessels from progressive burn necrosis in order to salvage a limb. The brachial artery should be totally isolated from the burned area by a muscle flap to prevent vessel disruption.
