Introduction: In this study rat abdominal skin flaps were observed daily to explain their contraction behavior and a mathematical formula has been developed.
Methods: 24 male rats were used for the study. Abdominal skin flaps based on the inferior epigastric neurovascular bundles were raised. In the first group all flaps were sutured to their donor area without any extra physical or chemical interference. In the second groups steroid was applied under the flaps to change the contraction rate.
Results: Contraction rate was significantly higher in necrotic tissues in both groups. A formula was used to correct for the contraction. The corrected results for the seventh day necrotic area percentage measurements were significantly higher than actual measurements. (p = 0.0001).
Conclusions: By using the mathematical formula developed in this study, pre-contraction value of the experimental skin flaps can be achieved and the results can be interpreted more accurately.

Background: The main technique for identification of free flap perforator vessels is Doppler sonography, which is not always accurate, user dependent and affected by the patient's body habitus.
Methods: Adult patients undergoing head and neck resection and free flap reconstruction at two academic institutions were enrolled. Doppler sonography was used to identify perforators, and were marked using a skin marker.

The free fibula flap is a common technique for mandibular bone defects. However, its limited skin paddle is disadvantageous in cases with significant soft-tissue defects. A free fibula dual-skin paddle flap is used for medium-sized soft-tissue defects.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that often necessitates extensive surgery when medical treatment fails, particularly in advanced stages. Traditional surgical approaches, including flaps and skin grafts, are effective for tissue coverage but can lead to vascular complications and recurrence of HS. This study introduces a novel technique, the apple-peeling procedure, combined with negative pressure wound therapy at -50 mm Hg for 5 days postoperatively.

Background: The goal of cytoreductive surgery for peritoneal malignancy is to remove all macroscopic disease, which occasionally requires the excision of the umbilicus. While the absence of the umbilicus can be aesthetically undesirable for patients, umbilical reconstruction is rarely performed due to the perceived complexity and increased risk of wound infections (Sakata et al. in Colorectal Dis 23:1153-1157, 2021).

Introduction: Despite its therapeutic advantages, postmastectomy radiotherapy (PMRT) increases the risk of complications and often leads to poor cosmesis in women undergoing breast reconstruction. Preoperative radiotherapy followed by skin-sparing mastectomy and deep inferior epigastric perforator (DIEP) flap reconstruction is technically feasible, with low rates of surgical complications and good short-term oncological outcomes. Further evaluation in a randomised trial comparing preoperative radiotherapy versus conventional PMRT in breast reconstruction is required to assess both oncological and patient-reported outcomes (PROs).
