Background: Foot ulcers in diabetic patients often require free flaps. A long vascular pedicle is mandatory so that more proximal vessels can be used as recipient vessels, especially when the flap is used to reconstruct distal foot defects. We evaluated the outcome of diabetic foot defect that were reconstructed using thoracodorsal artery perforator (TDAP) flaps with long vascular pedicles.
Patients And Methods: We reconstructed the foot defects of 22 diabetic patients. Nineteen patients were male, and the mean age was 56.4 years. The defects were located in big toe in 11 patients; fourth and/or fifth toe, including lateral aspect of the foot, in 8 patients; and dorsum of the foot, medial plantar, and first metatarsal medial head in 1 patient each. CT angiography showed that the two main vessels of the lower leg remained intact in 7 patients, only one vessel was intact in the lower leg of 11, and no vessels were visible in 4.
Results: The flap size ranged between 5 × 4 cm and 18 × 11cm , with a mean pedicle length of 16.5 cm. The anterior tibial artery was used as the recipient vessel in 15 patients, while the posterior tibial artery was used in 7. All the flaps survived. Three wound disruptions and two partial flap losses healed conservatively, without further surgery. Ulcer due to diabetes recurred in three cases. The mean follow-up period was 46.1 months. All wounds healed completely.
Conclusions: TDAP flaps with long vascular pedicles may be a viable choice for reconstructing defects in the feet of diabetic patients.

Background: Although the literature supports a shorter course of 24 h of prophylaxis after head and neck free flap reconstruction, studies supporting this duration do not differentiate between flap types. There is a paucity of evidence on the optimal duration of prophylaxis for osteocutaneous free flaps with hardware, which may have higher rates of post-operative complications compared to other free flaps. This study aimed to examine the effect of different lengths of antibiotic prophylaxis on surgical site infection (SSI) rates after head and neck reconstruction with osteocutaneous free flaps and hardware.

Background: The deep inferior epigastric perforator (DIEP) flap is currently the gold standard for autologous breast reconstruction. In cases where the DIEP is contraindicated, the profunda artery perforator (PAP) flap is now the preferred second-line option in our institution. The PAP flap poses unique challenges to the reconstructive surgeon, especially in Asian women with low body mass index (BMI).

The medial sural artery perforator (MSAP) flap is reliable in resurfacing defects of the popliteal fossa. There is possibility of resurfacing the popliteal fossa defects after postburn contracture release with scarred MSAP flaps with good overall long-term outcomes. A study was conducted from June 2017 to July 2023 to evaluate the functional and surgical scar aesthetic outcome in patients with soft-tissue defects in the popliteal fossa after postburn contracture release that were reconstructed using scarred and unscarred MSAP flap with 10 patients in each group.

Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.

Objectives: Virtual surgical planning (VSP) allows for optimal reconstruction of maxillary defects with fibula free flaps. Current data are limited regarding long-term complications of patient-specific plates (PSPs) in this setting. Our objective was to determine long-term complications of PSPs in maxillary reconstruction using fibula free flaps.
