Clinical Trial: Dissector Assisted Malar Elevation for Rhytidoplasty

Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional

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

Brief Summary:

BACKGROUND: Endoscopy was first used in plastic surgery for the treatment of frontal rhytides. This minimally invasive approach allows the treatment of frontal wrinkles using a practical procedure that does not directly interfere with the frontalis muscle, acting only on its antagonists.

It is also possible to treat the middle third of the face, but these evolutions depends on special surgical instruments. Videoendoscopic approach in rhytidoplasty have been improved by new devices and surgical instruments.

The mid third of the face can be treated in different ways. Zygomatic projection can be achieved by the use of the Dissector Assisted Malar Elevation (DAME) procedure.

AIM: Evaluate the zygomatic projection achieved by DAME in videoendoscopic rhytidoplasties.

METHODS: 30 non-white female patients, 30 to 59 years old, will be submitted to videoendoscopic rhytidoplasty with malar elevation by the DAME. Pre- and post-operative facial appearance will be evaluated by digital photogrammetry.


Detailed Summary:

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.

Skin antisepsis was performed with 0.2% aqueous chlorhexidine, followed by the placement of sterile surgical drapes, and retracing of the sagittal, parasagittal and temporal incision lines (described above) with methylene blue.

The right temporal incision was performed on the marked area, cutting through the skin and superficial temporal fascia, and exposing the deep temporal fascia. Followin
