Relaxed skin tension line-oriented keystone-designed perforator island flaps considering the facial aesthetic unit concept for the coverage of small to moderate facial defects.

ABSTRACT: A variety of reconstructive options including skin grafts, loco-regional flaps, and free flaps exist for the coverage of facial defects. Each technique has advantages and disadvantages. In this study, we present our experience with relaxed skin tension line (RSTL)-oriented, keystone-designed perforator island flap (KDPIF) reconstructions, in consideration of the facial aesthetic unit concept for coverage of small to moderate facial defects.Between May 2016 and February 2018, 17 patients (11 men and 6 women), with an average age of 63.53 years (range: 37-83 years) underwent KDPIF reconstructions to cover facial defects. We performed the KDPIF reconstructions in consideration of the RSTLs and facial aesthetic unit concept. We retrospectively reviewed the defect causes, locations, and sizes, and flap sizes, types, and survivals, as well as the complications. Cosmetic outcomes were evaluated using the Harris 4-stage scale from 3 independent plastic surgeons' point of view, and postoperative satisfactory surveys from all patients.All defects were successfully covered with KDPIF. The defect sizes varied from 1.5?×?1.5?cm to 3?×?3.5?cm. The flap sizes varied from 1.5?×?3?cm to 3?×?5.5?cm. All flaps fully survived and there were no postoperative complications. The average subjective patient satisfaction score was 8.29 (range: 7-10) and the objective cosmetic outcomes were favorable (fair, good, or excellent).Considering its simplicity and safety, the KDPIF is a good reconstruction option with few complications and high reproducibility. The RSTL-oriented KDPIF reconstruction is a good reconstructive option for covering small to moderate facial defects with superior aesthetic outcomes.

Project description:Background: Reconstruction with the use of perforator flaps makes it possible to make the skin surface resistant to the influence of mechanical factors and as similar to the lost skin cover as possible. However, while planning any flap, along with the design of the required shape and size, its blood supply should be taken into account to ensure optimal viability. Therefore, the task to precisely determine the topographic-anatomical relationships suitable for the formation of a pedicle of perforators is still relevant. The aim of this study was to increase the efficiency of surgical reconstruction of wound defects by transposition of locoregional perforator flaps. Methods: The authors conducted a retrospective analysis of 72 cases of reconstruction by means of locoregional perforator flaps with vascular pedicle detachment to determine the efficiency of preoperative diagnostic preparation with the help of multidetector-row computed tomographic angiography (MDCT) in the process of reconstruction. Thirty-seven individual cases of surgical interventions were chosen using a case-controlled study from the study group when MDCT with angiography was used for preoperative planning of perforator flaps, as well as 35 control cases similar in terms of important predictive peculiarities with the reconstruction at the same level of difficulty. The patient groups were precisely matched by gender (P = .950), age (P = .804), flap area (P = .192), and type of reconstruction that was performed. Results: In all cases, the location of the perforator with a diameter greater than 1.0 mm was marked. All perforators determined during MDCT scanning were faultlessly localized intraoperatively. The distance between the intraoperative position of the perforator and the position obtained in the result of the examination did not exceed 1 cm. There was no need to change the planned design of the flap intraoperatively. In all cases where MDCT was performed, the duration of the surgical procedure varied from 60 to 150 minutes (average: 120.77 [18.90] minutes) and was reduced by 49.40 minutes (95% CI: 39.17-59.63) compared with the patients who did not undergo preoperative visualization of perforators where the average duration of the operation was 170.17 (19.19) minutes (from 140 to 220 minutes). Among the patients examined by MDCT, surgical complications were noted in 5 cases (13.51%) compared to 14 cases (40.00%) in the control group. Conclusions: The preoperative MDCT for the locoregional perforator flap reconstruction makes it possible to increase the efficiency of patient treatment given the reduction in surgery duration by 49.40 minutes (95% CI: 39.17-59.63) on average and the reduction in the level of postsurgery complications from 40% to 13.5% compared with the group of patients in whom presurgical visualization was not performed (P = .031).

Project description:Background & objectivesVarious oncoplastic techniques have emerged over the years to preserve breast cosmesis and symmetry without compromising the principles of tumor excision. One of the newer techniques for breast volume replacement to achieve symmetry and cosmesis is the use of fasciocutaneous pedicled chest wall perforator flaps or local perforator flaps (LPF). The objectives of this study were to document the details of the surgical procedure as well as patient-reported satisfaction and well-being following the procedure using a validated BREAST-Q tool among Pakistani women.Materials & methodsThis cross-sectional study was conducted from March 2019 to February 2021 enrolling 25 female patients who underwent breast conservative surgery using LPF for breast tumors at The Aga Khan University Hospital, Karachi. Data related to the procedure was collected on a pre-designed proforma. Cosmetic outcomes and patient satisfaction were evaluated using 2 scales from BREAST-Q BCT domain version 2.0. The questionnaire was self-administered by the patients during their routine follow-up in the clinic. Data was analyzed using the Statistical Package for Social Sciences (SPSS) version 23. Mean (SD)/median (IQR) were computed for quantitative variables and frequency and percentages were calculated for qualitative variables. 2 sample t-test was applied. P-value ≤0.05 was considered significant.Results25 patients underwent LPF with a mean age of 47 ± 13.1 years. 8 LICAP, 7 AICAP, and 10 LTAP flaps were performed. Two postoperative complications of wound site erythema were encountered. 23 women were eligible for the BREAST-Q survey. Median (IQR) postoperative satisfaction with breasts and physical well-being chest (equivalent Rasch transformed score) was 100 (41) and 76 [18] respectively. We found high satisfaction with breasts and comparable physical well-being among Pakistani women after LPF surgeries.ConclusionLocal perforator flaps in oncoplastic breast-conserving surgery are a good option showing high satisfaction with breasts and physical well-being in Pakistani women.
