Endoscopic correction of eyebrow asymmetry in associated forehead soft-tissue injuries.

Supported by anatomical principles, a subgaleal endoscopically assisted selective myotomy of the forehead and glabellar muscles was used to achieve eyebrow symmetry in patients with unilateral facial nerve palsy and associated forehead soft-tissue injuries. Selective myotomy equalizes the agonist-antagonist muscle relationship on both sides of the forehead, thereby allowing the untouched muscle to exert its activity without opponent restriction. Selective myotomy allows for the management of the muscles' group action as well as individual manipulation of each muscle in accordance with its participation in the eyebrow deformity.

Mammaplasty combining vertical and transverse approaches through a vertical incision.

An adjustable vertical marking is described for vertical mammaplasty in mild and moderate hypertrophy or ptosis of the breast. A vertical rectangular flap with the pedicle supported at the inframammary fold provides fullness for the upper or the lower pole of the breast. It is fixed over the pectoralis aponeurosis along the upper pole to the base of the pedicle. Length, width, and thickness of the vertical rectangular flap change regarding the extent of breast ptosis and hypertrophy. Two transverse triangular flaps, dissected in the lower pole of the breast, are supported on the inferior half of the vertical pillars at the incision margins. The criss-crossing of the triangular flaps creates a transverse support sling, avoiding the downward displacement of the breast. The vertical flap is applied in conjunction with the triangular flap to attempt to achieve projection and support for the breast with long-term stabilization of the mammary cone. Resection of mammary tissue is performed transversely just above the pedicle of the vertical flap.

Selective myotomy in forehead endoscopy.

Endoscopic forehead surgery in a subgaleal plane allows selective manipulation of the forehead and glabellar muscles in accordance with their influence in forehead and brow deformity. Myotomy begins by interrupting the blend of the fibers of the elevator and depressor muscles, thereby exposing the bone fixation and cutaneous insertions of the depressor muscles. Myotomy of the depressor group is performed by section of the muscle fibers as close as possible to their bone fixation, with release of the cutaneous insertions at the brow level. The involuntary frontalis contraction free from the active opposition of the depressor muscles and free from the restriction of the inelastic structure of the periosteum stabilizes the brow elevation and gives a natural, long-term result. No fixation methods are used to hold the forehead flap in position. Transverse section of the frontalis muscle is performed to restore brow symmetry or excessive lift of the brow.
