Background: Skull base reconstruction is challenging due to its proximity to important anatomical structures. This report evaluates the use of perforator flaps for reconstruction of skull base defects after advanced recurrent tumor resection.
Methods: Fourteen free perforator flaps were transferred to reconstruct skull base defects in 14 consecutive patients, from October 2004 to May 2011. All patients had advanced recurrent neoplasms that were previously treated with either radiation therapy or surgery. The surgical defects were reconstructed using various perforator flaps mainly the deep inferior epigastric artery perforator flaps, anterolateral thigh (ALT) flaps, or thoracodorsal artery perforator flaps. The outcomes following reconstruction and associated complications were evaluated.
Results: The overall free flap success rate was 93% (13/14). One ALT flap was lost. Three patients (20%) had a cerebrospinal fluid fistula, and two of them developed meningitis. No complications were observed at the donor site.
Conclusions: The use of perforator flaps may be a viable option for reconstruction of skull base defects after the resection of advanced recurrent tumor.

Background: The purpose of this study was to evaluate the present-day practices in the preparation, peri-, and postoperative care for patients undergoing autologous free flap breast reconstructions (ABR) worldwide, with the aim of enhancing informed decision-making for plastic surgeons during the planning stages of ABR.
Methods: A global survey was conducted among 280 plastic surgeons and 39 plastic and reconstructive surgery societies worldwide, enquiring about flap and donor site selection, surgical actions, perforator imaging, and perioperative care during ABR.
Results: Eighty-two responses were received, among which 71% (n=58) were completed questionnaires.
Reconstruction of Abdominal Defects After Open Abdomen Treatment Using Propeller Flaps of the Superior and Deep Inferior Epigastric Artery System: Report of Two Cases.

Open abdomen treatment (OAT) is associated with significant morbidity and mortality. In cases where primary or delayed fascial closure cannot be achieved, vacuum-assisted wound closure and mesh-mediated fascial traction are indicated, which often result in a planned ventral hernia. If secondary skin closure is not feasible, common treatment of granulated abdominal defects involves split-thickness skin-grafting or healing by secondary intention leading to significant scarring and sometimes mutilating defects.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

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.
