A new surgical planning pattern is described that permits application of the "coning principle" of the regional tissue after mammary reduction. It makes use of a superior vertical dermal pedicle for nourishing the nipple-areola complex. The pedicle is not connected to the subjacent mammary tissue and thus can be folded over itself to accommodate the nipple-areola area at its new position.
The release of abnormal insertions of orbicularis oris muscle from the columella and ala base, and from their inferior attachments along the labial margin, provides muscle flaps for a double-breasted suture in cleft lip repair. Using the muscle flaps for double-breasted sutures realigns the orbicularis oris muscle fibers to achieve an anatomical and functional repair that is characterized by a symmetrical lip length, nostrils, philtral column, and philtral dimple. Double-breasted sutures also increase muscle thickness surrounding the lip and consequently provides better symmetry for the nostril floor.
The authors present an addition to standard abdominoplasty techniques. Transverse plication of the aponeurotic layer in the epigastrium corrects the prominence in this area and helps the flap to reach the pubic region.

Using Webster's technique for treating gynecomastia, the removal of the excess breast tissue is facilitated by the use of liposuction introduced through the axillary incision. In the case of pseudogynecomastia, only liposuction via the axillary approach is recommended.
Heterologous collagen matrix sponge has been used to prepare third-degree burn wounds for autologous skin graft. The porosity and the multiple connections among the interstices of the sponge enable ready ingrowth of endothelial and inflammatory cells. Heterologous collagen matrix sponge also increased the rate of formation of granulation tissue in burn wounds.
