Non-randomized Clinical Trial for Evaluation of the Dissector Assisted Malar Elevation in Videoendoscopic Rhytidoplasty.

THE NEW SURGICAL INSTRUMENT:

The dissector developed by the authors is a stainless steel instrument, 20 cm in length, 1 cm in diameter, with a cylindrical handle, and an articulated section 3 cm in length and 1cm in diameter at the distal end. When the most proximal end of the handle is rotated, the articulated section provides for angulation or articulation of the distal end portion with respect to the longitudinal axis of the instrument that is similar to the movements of a distal phalanx of a finger.

SURGICAL TECHNIQUE:

1. Frontal Region: An incision line, 2 cm long, in the median sagittal plane and 1 cm from the hairline; an incision line, 2 cm long, parallel and 4 cm from the sagittal line, to the right and left sides;
2. Temporal Region: An incision line, 3 cm long, 3 cm from the hairline, perpendicular to and bisected by a line traced from the margin of the nasal wing, passing by the lateral palpebral commissure and extending in the posterior direction, bilaterally.

Following, the hair was gathered into bundles to allow access to the skin markings, and held by latex rings, which were obtained by cross-sectional cuts through fingers of sterile latex surgical gloves.
