The frontal hairline is the most important and difficult part of hair reconstruction. A technique is presented that uses '~ to correct a frontal hairline that looks less than natural, a condition often seen after punch hair grafting (or strip grafting or scalp flaps). With these "micrografts," it is possible to produce a natural-looking, soft frontal hairline, hiding an unnatural-looking, dense hairline that starts abruptly with coarse hairs. It is also possible to hide disturbing visible scarring or cobblestoning of the foremost punch grafts and differences in color between the grafted skin and the recipient area.

Tissue expansion has become the most important method for postmastectomy breast reconstruction. However, well-defined inframammary fold and ptosis are difficult to achieve with this technique. This study was performed to evaluate the inframammary fold and ptosis achieved in breast reconstruction using a textured tissue expander, later replaced by a textured implant. In ten postmastectomy patients, a textured tissue expander was inserted into a submuscular pocket. Every two to three weeks the volume of the expander was increased by about 30%. About three months after the last filling, the expander was removed and replaced with a permanent textured, gel-filled implant. The profile of the reconstructed breast was recorded before and after the tissue expansion, as well as before and after the change of the implant. The results showed that the inframammary fold did not move significantly upwards or downwards during the expansion period when a textured tissue expander was used. Waiting three months after the last inflation of the expander before replacing it with the permanent implant resulted in a more ptotic breast mound. Usually, however, no real ptosis was achieved, meaning that the angle between the lower part of the breast and the lower chest wall was more than 90 degrees. These findings indicate that a textured expander could help create a pronounced inframammary fold, but without ptosis. A three-month waiting period before inserting the permanent implant may improve the development of an inframammary fold.

Although, at present, it is generally assumed that lowering the metabolism of grafts by reducing their temperature may be of some utility for enhancing their survival rate, our data indicate of that there are no effects when performing hair transplantation surgery.

The aim of the present study was to evaluate to what extent undermining affects the closing-tension of scalp defects to quantify the surgery-related benefits provided by this procedure. Data were collected by stepwise loading in 10 patients, 20 scalp flaps (obtained by a reversed Y scalp incision), and three different degrees of subgaleal undermining (1, 5, and 15 cm). The obtained data confirmed the value of undermining to diminish the tension on wound margins when closing a scalp defect. There was a progressive decrease in tension required to advance the wound edge when the amount of undermining was sequentially increased. Most of this reduction occurred with the 5-cm undermining, although statistically the 15-cm undermining also resulted in a significant decrease in the tension required to close the defect. Mean 83.3- and 92.2-percent reductions of the closing tension were obtained with 5 cm and 15 cm of undermining, respectively, compared with that achieved by the 1-cm undermining with the same width of defect.
