The results suggest that Furlow palatoplasty performed in later years improves not only speech but also velopharyngeal closure by reorienting the levator veli palatini muscle and augmenting the velum.

Nasal augmentation required following a trauma or a rhinoplasty operation poses a challenging problem to many plastic surgeons. Currently, allografts and autologous tissues are used for nasal augmentation; however, an ideal technique has not yet been described. Although preferred for augmentation of different parts of the body, pure dermal graft use has not been described for nasal augmentation. The authors performed nasal augmentation using a dermal graft in 90 patients in their hospital between 1994 and 2000, and they followed up the patients for 6 months to 8 years. In this article, the early and late results of dermal grafts for nasal augmentation are presented, and their advantages and disadvantages are discussed with a review of the literature. It was concluded that the easily obtained dermal graft could be an appropriate alternative in nasal augmentation, though it has not been used widely for this purpose.

Pulsed dye laser has been found to be safe, effective, satisfactory, and less traumatic compared to other options for treatment of perianal warts in children.

Fat tissue is abundant in the body and preferred in soft tissue augmentation. Since resorption is its greatest disadvantage, many agents have been tried in an attempt to increase fat graft survival in various studies. Yet selective beta1 blocker had not been used before. The effect of selective beta1 blockers on resorption following auto-transplantation of free fat graft was examined in rats. The effect of selective beta1 blockers was compared with those of insulin and saline solution as a control. For this comparison, the weight of fat grafts was measured both during and nine months after operation using the "liquid overflow method" in which obtained material was put into 5 cc syringe filled with saline solution and the increase in liquid level was recorded as graft volume. Histological examination of grafts and statistical analyses of the results were also made. Our in vivo study demonstrated that selective beta1 blocker significantly increased free fat graft survival. It is our conclusion that selective beta1 blocker is a promising agent for decreasing fat graft resorption.

Reconstruction of columella presents certain difficulties and includes reconstruction of the cartilaginous strut and the overlying skin to obtain good results. We conducted a retrospective clinical review of 38 patients presenting with congenital and acquired columellar defects. Anatomic characteristics to be considered were defined and a classification method is proposed to more fully describe columellar defects. The columellar defects of the patients were classified into three groups as follows: type I, skin defect of columella and absence of medial crura of lower lateral cartilage; type II, type II + partial absence of caudal part of septal cartilage; and type III, complex defect of columella accompanying with the other nasal subunit defects. The patients chosen in this study were designed to describe a common approach for the choice of the reconstruction method that provides excellent aesthetic result while minimizing the extent of the surgery and maximizing patient acceptance.

This experiment was designed to investigate whether addition of vitamin C to the solution used in tumescent technique of liposuction might increase lipolysis and whether increased fibrosis might improve skin retraction where liposuction did not work properly and the skin had poor retraction ability. Eighteen Sprague-Dawley rats were used in two groups. Both inguinal fat pads of rats with their vascular structures were elevated and the right inguinal fat pad was injected with 1 cc tumescent solution as a control and the left fat pad with a 1 cc vitamin C-tumescent solution. Histopathological examination showed that all fat pads injected with tumescent solution had normal adipocytes. Those injected with vitamin C-tumescent were shown to have extreme fibrosis and occasional adipocytes.
