Background: Augmented reality (AR - augmented reality) is the addition of digital information to one or more senses, which allows the user to perform tasks more efficiently. This can be achieved by overlaying images, videos, or computer models., Objective: The aim the study is to study the use of AR for preoperative planning of perforant flaps and compare the results of visualization accuracy of various research methods., Materials and Methods: 3 patients with oncological diseases were examined, who were planned to lift and transplant a SCIP flap (in two cases) and a propeller flap on the perforant branch of the peroneal artery (in one case). All patients underwent a high-frequency ultrasound of 75 GHz examination of the donor zone and marking along it in the area of the planned flap lift. A CT scan of the donor area was also performed, followed by the superimposition of a segmentation image using HoloLens 2 virtual reality glasses. 7 measurements were obtained., Results: AR for microsurgical planning was performed in two inguinal regions and was 100% correlated with the results of high-frequency ultrasound, in the case of perforant vessels of the peroneal artery, a discrepancy of 5 mm was noted for the X and Y axes in three perforant vessels., Conclusion: Augmented reality allows the reconstructive surgeon to see the anatomy of the area of interest in a particular patient before the incision. This area of medicine is certainly in demand, promising and requires further research with larger patient samples and randomization.

Most of the articles on the groin flap were published in the period from 1975 to 2010, from 2015 to 2022, the SCIP flap surpassed the groin flap in the number of publications. According to the results of a literature search in PubMed and RINC, 30 articles were found and selected, including 288 flaps from the iliac region. The length of the vascular pedicle, the diameter of the vessels, the complications, the prevalence of the flap in the reconstruction of the head and neck, the thickness and the size of the flap were evaluated. Both of these flaps have the same nutrition, but different levels of dissection. In comparison with the groin flap, the SCIP flap has a longer vascular pedicle, which can be enlarged due to new techniques, which also allows it to be used as an ultra-thin flap, and it reduces the need for secondary procedures for defatting and reduces the risks of the complications in the donor area. The thickness of the SCIP flap is less than the groin one, which, according to the author, increases the aesthetic level of operations in the facial area in the case of the texture and color of the flap. Vascular anatomy of the SCIP flap is variable, therefore, the use of preoperative planning is necessary. Despite this, complications in the donor or recipient area during reconstruction with a SCIP flap are minimal. It has been proved that the SCIP flap is versatile and safe in all aspects of reconstruction. It can be concluded that the SCIP flap should be considered as a «workhorse» in reconstructive microsurgery of soft tissues of the throat and oral cavity.
