Analysis of Mechanical Behavior of Dermal Fibroblasts Obtained From Various Anatomical Sites in Humans.

Purpose: Facial skin fibroblasts imposed with cyclic stretch at 10% magnitude display considerable mechanotransduction properties and biochemical reactions in our previous study. However, it is poorly understood how these shared traits are fully parallel to the common features across all fibroblasts derived from different skin-based anatomical regions in response to cyclic stretch stimulation. Thus, the purpose of this study was to evaluate the effects of various cyclic stretches on fibroblasts derived from multiple anatomical skin sites of human bodies, and the optimal stretch magnitude was defined based on the changes to cell mechanical behavior.

Principles of hatchet-skin flap for repair of tissue defects on the cheek.

Background: To date, cheek reconstruction remains a challenge for plastic surgeons. This report presents the authors' cheek reconstruction technique with different types of hatchet-skin flaps, which provides satisfactory results.

Methods: The cheek area was divided into three parts (P1, P2, and P3), with vertical lines passing through the medial and lateral canthus.

[Application principles of hatchet skin flap for repairing tissue defect of cheek].

Objective: To evaluate the design principles, clinical results and significance of hatchet skin flaps for repairing tissue defects in different parts of cheek.

Methods: The area of cheek was divided into three parts, P(I), P(II) and P(III), with vertical lines through the medial canthus and lateral canthus. Different kinds of hatchet skin flaps were designed to repair tissue defects in different part of cheek.

[Effect of the tumescent infiltration solution temperature on body temperature].

Objective: To evaluate the effect of tumescent infiltration solution temperature on core body temperature after liposuction.

Methods: 15 healthy female subjects were randomly divided into 2 groups to receive tumescent infiltration solution at 25 degrees C as group A, or at 37 degrees C as group B. All subjects were under epidural anesthesia.

[Application of hatchet flap for buccal tissue defect].

Objective: To evaluate the therapeutic effect of hatchet flap for buccal tissue defect.

Methods: The hatchet flap was designed beside the tissue defect and advanced to cover the defect.

Results: Since 2006, 13 cases were treated with primary healing and no flap loss.
