AI Article Synopsis
- This study looked at helping patients with difficult skin and muscle problems caused by surgery for tumors near the tailbone area.
- They used a special technique called the chimeric perforator propeller flap to rebuild the damaged areas for 7 patients over several years.
- The results were mostly good, with no serious issues or infections in the treated areas, and patients did not have muscle weakness or see their tumors come back.
Article Abstract
Background: Complex soft tissue defects, which result from the surgical resection of sacral tumors, manifest as a combination of skin defects, dead space, infection, and prosthesis exposure. Because the traditional musculocutaneous flap lacks flexibility because of the close connection between the skin flap and the muscle component, the musculocutaneous flap is not suitable for reconstructing complex soft tissue defects where the dead space and skin defects are located at different sites. Furthermore, the perforator flap is also not appropriate for reconstructing complex defects because it lacks the muscular component. We considered the possibility of using the chimeric perforator propeller flap for reconstructing complex sacrococcygeal defects.
Methods: This study included 7 patients who underwent, between July 2007 and July 2021, the reconstruction of complex soft tissue defects of the sacrococcygeal region using a chimeric perforator propeller flap.
Results: Among the included cases, the etiologies were chordoma (n = 3), sacral tumor (n = 3), and squamous cell carcinoma (n = 1). In all the cases, vacuum-assisted closure therapy was used to treat wound infections before surgery. The average sizes of the skin and muscle flaps were 195.8 cm 2 (range, 100-350 cm 2 ) and 83.6 cm 2 (range, 60-140 cm 2 ), respectively. The superior gluteal artery was the source artery for the chimeric perforator propeller flap. The donor sites were primarily closed in all cases. One patient had delayed wound healing, and the secondary wound healed using conservative dressing changes. The other 6 flaps had no complications. The average follow-up time was 5.3 months (range, 1-9 months). Muscle weakness and compromised ambulation in the affected lower extremities were not observed in any of the patients. Furthermore, all 7 patients had no tumor recurrence, prosthesis exposure, and infection events in the sacrococcygeal region.
Conclusions: The chimeric perforator propeller flap may be an option for reconstructing complex soft tissue defects in the sacrococcygeal region.

Chimeric anterolateral thigh flap for reconstruction of complex defects in oral cancer: a report of three cases.

It is crucial to reconstruct extensive soft tissue defects following oral cancer resection to restore both function and aesthetics. Single anterolateral thigh flaps may not suffice for large defects. This report highlights the use of chimeric flaps, which feature multiple paddles with individual perforators, to reconstruct large intraoral and extraoral defects, adapting to wide defects, and covering areas with extensive tissue damage.

Background: Complex lower extremity defects are difficult to cover and often require multiple free tissue transfers. Chimeric anterolateral thigh free flaps (ALTF) and peroneal artery perforator free flaps (PAPF) have been designed specifically as an alternative for reconstruction with arterial end-to-side (ETS) anastomosis. We aimed to assess our institutional experience with this technique and to define its role in complex lower extremity reconstruction.

An extended orbital exenteration defect in a male in his mid-80s was successfully reconstructed with a medial sural artery perforator flap. To our knowledge, this flap has not been described in the literature for such defects until now. While it may require meticulous intramuscular perforator dissection, it provides several advantages; it is thin, pliable, has a long pedicle of large calibre facilitating microanastomosis and provides adequate coverage where the amount of chimeric muscle can easily be tailored to the defect's surface area and volume.

Background: Superficial circumflex iliac vein (SCIV) and venae comitantes were qualified for traditional superficial circumflex iliac artery perforator (SCIAP) flaps. Optimal approaches for multipaddle and chimeric SCIAP flaps remain elusive. The purpose of this study is to investigate validities of SCIV-only and VCs-only conduits for such extended SCIAP flaps.

Article Synopsis
- The study focuses on the use of deep circumflex iliac artery (DCIA) flaps for reconstructing maxillary defects, aiming to improve surgical efficiency and outcomes through computer-assisted techniques.
- Researchers reviewed 10 cases of maxillary reconstruction, noting various types of defects and documenting donor site choices, types of flaps used, and the success of surgical procedures.
- Results indicated 9 successful recoveries with no complications, while one case required additional surgery due to necrosis, demonstrating the potential reliability of the DCIA flap method when combined with advanced technology.
