The new bilaterally pedicled V-Y advancement flap for face reconstruction

A new bilaterally pedicled V-Y advancement flap based on two subcutaneous pedicles that vascularize the skin island through subdermal plexus lateral bridges is described for face reconstruction. It differs from traditional V-Y advancement flaps in that it does not rely on the classic subcutaneous "vertical" pedicle that is sectioned from top to bottom to improve advancement of the skin island. This technique had predictable results for 12 years in 425 consecutive patients, with infection occurring in 2.8 percent of the cases and complete necrosis in less than 1 percent of the flaps.     

V-Y advancement flaps for closure of nasal defects

The nose is a difficult anatomic region in which to close defects resulting from resection of cutaneous malignancies. The V-Y flap is a technique for advancing adjacent tissue, thereby achieving wound closure while minimizing tension. A total of 120 V-Y flaps were used to close 114 nasal defects. The average defect size was 13.5 x 11 mm. Partial flap loss occurred in five patients, with total flap loss in one. One wound infection and two hematomas occurred.     

Levator advancement technique for eyelid ptosis

There have been many procedures advocated for the treatment of eyelid ptosis. The technique advocated in this paper consists of careful dissection and identification of anatomic landmarks, including preaponeurotic fat, Whitnall's superior transverse ligament, and the vertically oriented blood supply of the levator muscle. The attachment of the levator muscle into the cephalad portion of the levator muscle into the cephalad portion of the levator aponeurosis can be identified and easily dissected in order to perform the procedure of detachment and advancement to the tarsal plate. This procedure for ptosis has been successful in management in moderate to severe ptosis and in some cases has actually increased the muscle function, thereby enhancing the result. In this technique, the full length of levator muscle remains, so maximum excursion is achieved postoperatively. In addition, this surgical approach may be utilized for levator-lengthening procedures in cases of thyroid exophthalmus or overcorrected ptosis simply by performing the reverse procedure of detachment and insertion of a spacer based on the same ratio. Good results have been achieved in over 20 patients, with the exception of two patients who had absent to poor function and in whom undercorrection was present postoperatively.     

The prevention and treatment of lower lid ectropion following blepharoplasty

Ectropion and scleral show are the most common complications following lower lid blepharoplasty. Certain conditions predispose patients to ectropion, and these should be evaluated. In some cases, the addition of a wedge tarsectomy or tarsal strip procedure to a blepharoplasty in association with careful technique and postoperative measures is important in prevention of postblepharoplasty ectropion. Postoperative ectropion should initially be treated conservatively with massage. This may be effective up to 6 months postoperatively. If conservative measures fail, the etiology of the ectropion should be addressed. Laxity of the tarsus and canthal ligaments benefit from a horizontal lid-shortening procedure. Where there is vertical shortening from excessive skin resection or scarring of the orbital septum, there should be release and grafting of the deficiency.     

The evolution of the Hughes tarsoconjunctival flap for the lower eyelid reconstruction

The Hughes tarsoconjunctival flap was initially described in 1937. This flap is best used for reconstructing full-thickness defects involving the central portion of the lower eyelid. The evolution of this flap over the last 60 years is outlined. Several important modifications are presented; these modifications lead to decreased donor-site morbidity and improved recipient site outcome.     

Prefabricated (expander) capsule-lined transposition and advancement flaps in reconstruction of lower eyelid and oral defects: an experimental study

In six pigs with prefabricated transposition flaps and six pigs with prefabricated advancement flaps, both flap types (lined with an expander capsule) were used to reconstruct wedge excisions of the lower eyelid or defects in the cheek/oral mucosa. The capsules replaced the conjunctiva in eyelid defects and the oral mucosa in cheek defects. Histopathologic studies were performed at 5 to 7 days, 9 to 10 days, 2 weeks, 3 to 4 weeks, and 2 and 3 months after flap reconstructions. Healing was rapid and uneventful, leading to restoration of the conjunctiva/eyelid and oral mucosa between 9 days and 2 weeks. The healing of the eyelid conjunctiva was somewhat faster than of the oral mucosa. The expander capsule acted as a conjunctival/ mucosal substitute, providing a temporary physical shield, an infectious barrier, and a matrix for epithelial regeneration. All reconstructions were successful except one oral reconstruction with early flap necrosis. Flaps lined with an expander capsule could improve and facilitate clinical reconstructions in the eyelid and oral cavity.
