Background: It is important to include as many perforators as possible in order to enhance the vascularity of a deep inferior epigastric perforator (DIEP) flap. However, the rectus muscle must be transected transversely, which prevents suturing and can cause a defect along the same line as the muscle-sparing procedure. When harvesting the DIEP flap, no specific method was suggested to solve these muscle defects.

Background: Use of coupling devices in microvascular anastomosis continues to increase, but it is not yet actively used in end-to-side (ETS) anastomosis because there is no standard method. Therefore, we propose an easy and time-saving ETS micro-anastomosis method using coupling devices in head and neck reconstruction and compare it with the conventional suture method.

Materials And Methods: We retrospectively reviewed 30 consecutive cases (43 anastomoses) of ETS anastomosis in head and neck reconstruction from 2018 to 2022.

The anterolateral thigh (ALT) skin flap provides abundant, thin, pliable skin coverage with adequate pedicle length and calibre, and tolerable donor site morbidity. However, coverage of relatively large defects using the ALT flap alone is limited. We present our experience of using the ALT flap coupled with the vastus lateralis (VL) flap supplied by the same pedicle for large defect reconstruction.

Maintaining the patency of the external auditory canal (EAC) during reconstruction is important because of its physiological role in hearing and immunological protective functions. The curved shape of the EAC presents a challenge when performing a skin graft. One of the key points for a successful skin graft is to ensure compression on the wound bed, and many novel methods, including prefabricated ear molds, have been reported for this purpose.

Background: Volume changes in reconstructed flaps, particularly regarding symmetry, are an important consideration to improve long-term esthetic results in patients who undergo breast reconstruction. Asian patients with thin abdominal tissues tend to require bipedicled flaps, which provide a greater volume of abdominal tissue. We investigated volume changes in free abdominal flaps and the factors that may affect flap volume, particularly the number of pedicles.

Despite the high success rate in reconstruction using free tissue transfer, flap failure is often caused by microvascular thrombosis. In a small percentage of cases with complete flap loss, a salvage procedure is performed. In the present study, the effectiveness of intra-arterial urokinase infusion through the free flap tissue was investigated to develop a protocol to prevent thrombotic failure.

Article Synopsis
  • The latissimus dorsi myocutaneous (LDMC) flap is widely used in breast reconstruction due to its large surface area but poses challenges with traditional lateral approaches.
  • A new 'anterior-first' approach allows surgeons to access important structures more efficiently by starting from a supine position through the mastectomy incision.
  • A study comparing the two methods found that the anterior-first approach significantly reduced reconstruction and flap elevation times without increasing complication rates, improving overall surgical ergonomics.

Reconstructive treatments of heel defects usually involve regional flap techniques such as medial plantar flap procedures due to the limited availability of adjacent soft tissues. Although free flaps have advantages in terms of function and aesthetics, they remain challenging due to the longer operation time required than for regional flaps. Thus, we introduce an appropriate 2-team surgical protocol to reconstruct plantar defects after wide excision of malignant melanoma using free flap coverage.

Despite the popularity of breast reconstruction with abdominal flap, the integrity of the abdominal wall gets compromised after the operation. To decrease donor site morbidity, researchers have developed various inlay or onlay graft materials. However, the indications of use are unclear and dependent on the subjective decision of the surgeons.

Purpose: Capsular formation around breast implants can produce various complications, including erythema, tenderness, discomfort, and breast deformation. Moreover, the capsule is thought to be correlated with breast implant-associated anaplastic large cell lymphoma. The proposed technique of capsule reduction can prevent some of these complications.

Background: Angiogenesis and vasculogenesis are essential processes for successful tissue regeneration in tissue engineering and regenerative medicine. The adipose-derived stromal vascular fraction (SVF) is not only a source of adipose stem cells (ASC) but also a suitable source of microvascular endothelial cells because it is a rich capillary network. So, we propose a new hypothesis for isolating adipose-derived human microvascular endothelial cells (HMVEC-A) from the SVF and developed a dual isolation system that isolates two cell types from one tissue.

Temporal hollowing is most frequently an acquired deformity and can be caused by volume defects of bone, soft tissue, or both. Recently, surgical reconstruction with autogenous fat or allografts has been introduced, but these materials can be resorbed over time and may also lead to infection. Herein, the authors present 2 cases demonstrating the treatment of temporal hollowing with a superior gluteal artery perforator (SGAP) free flap.

Background: In microvascular anastomosis, size discrepancy is common and can increase thrombotic complications. If size differences can be predicted, then vessels of the appropriate size can be selected. This study documented the difference in diameter between the thoracodorsal (TD) vessel and deep inferior epigastric perforator (DIEP) pedicle in each patient who underwent breast reconstruction using free tissue transfer.

Background: The necrotic change may sometimes occur in peripheral parts of the flap when harvesting a wide flap in a patient with a relatively thin thigh in anterolateral thigh (ALT) flap. Here, we explore the prophylactic measure of turbocharging the ALT flap with anteromedial thigh (AMT) perforator based on the circumference of the patient's thigh to reduce the risk of partial flap necrosis for the reconstruction of wide defects.

Patients And Methods: From January 2015 to December 2017, extended ALT perforator turbocharged flaps were done in nine patients.
