“…Zhang and Li, respectively, dissected saphenous artery flap and sural neurocutaneous island flap with the assistance of three‐dimensional digital technology to repair soft tissue defects in lower limbs. It was found that digitalized technology could improve surgical accuracy, increase the survival rate of the flap, and decrease the operation time [12, 13]. Considering the individual differences in the anterior tibial artery perforators and the shortcomings of traditional methods, we used three‐dimensional digitalized technology to study the perforators accurately and reveal the in‐depth relationship between the length of the perforator and its origin, as well as the diameter law of the perforators coursing in the different septum, so as to guide the dissection of the patient‐specific anterior tibial artery perforator flap.…”

Background Traditional research methods have limited the application of anterior tibial artery perforator flap due to incomplete knowledge of the perforator. This study aimed to investigate the feasibility of three‐dimensional digitalized virtual planning of free anterior tibial artery perforator flap for repairing soft tissue defects in extremities. Methods A total of 11 patients with soft tissue defects in extremities were included. The patient underwent computed tomography angiography (CTA) of bilateral lower limbs, and then the three‐dimensional models of bones, arteries, and skin were constructed. Septocutaneous perforators with appropriate length and diameter were selected to design anterior tibial artery perforator flaps in software, and the virtual flaps were superimposed onto the patient's donor site in a translucent state. During the operation, the flaps were dissected and anastomosed to the proximal blood vessel of the defects as designed. Results Three‐dimensional modeling showed clear anatomical relationships between bones, arteries, and skin. The origin, course, location, diameter, and length of the perforator obtained during the operation were consistent with those observed preoperatively. Eleven anterior tibial artery perforator flaps were successfully dissected and transplanted. Postoperative venous crisis occurred in one flap, partial epidermis necrosis occurred in another flap, while the remaining flaps completely survived. One flap was treated with debulking operation. The remaining flaps maintained aesthetic appearance, which did not affect the function of the affected limbs. Conclusions Three‐dimensional digitalized technology can provide comprehensive information on anterior tibial artery perforators, thus assisting in planning and dissecting patient‐specific flaps for repairing soft tissue defects in extremities.

Background: Current guidelines for randomized controlled trial reporting do not require authors to justify their choice of time horizon. This is concerning, as the time horizon when an outcome is assessed has important implications for the interpretation of study results, and resources allocated to an investigation. Therefore, this study seeks to examine the standards of time horizon reporting in the plastic surgery literature. Methods: This is a systematic review of plastic surgery randomized controlled trials published within the past 4 years. The MEDLINE database was searched to yield relevant studies. All studies included were English language, prospective, nonpharmaceutical randomized controlled trials, comparing two plastic surgical interventions. Studies were classified into plastic surgery domains, and information regarding study population, time horizon reporting, and justification of chosen time horizon, was extracted. Results: The search retrieved 720 articles, of which 103 were eligible for inclusion. Time horizons were reported as either a standardized time point at which all patients were assessed, or a follow-up duration range, or were not reported at all. Although most studies (85.4 percent) reported a standardized time horizon, the majority (85.4 percent) failed to provide a valid justification to support their selection of time horizon. Conclusions: Clinical investigators failed to justify their choice of time horizon in the majority of published randomized controlled trials. To limit heterogeneity, time horizons for given interventions should be standardized to improve validity of outcome assessments, enable future pooling of results, and increase research efficiency.
