“…Limited rotation or deformation remains smooth incisions which usually is similar to triangular kite -kite flap-to reach the real distribution of tissue stress [5]. Dölen et al [6] designed templates to V-Y rotation advancement flaps as unilaterally or bilaterally to have lest donor site pincushion and morbidity.…”

Introduction: lower lid malposition following malignancy surgery in infra-orbital area is often challenging and any way to reduce its chance is appreciated. Case presentation: 36 years old women with confirmed Basal Cell Carcinoma (BCC) of left cheek underwent tumor excision with free margins and remained skin defect reconstructed with adipocutaneous v-y advancement flap, which designed in a horizontally orientation. Patient had no signs of ectropion with good wound repair and obscured scar. Conclusion: v-y flaps are commonly used local flaps with minimal donor site morbidity, and if designed horizontally, not only may reduce chance of lower lid malposition, but also can remain more acceptable scars.

Background The digital artery-based V–Y advancement flap is a widely used flap for soft tissue coverage in the treatment of flexion contracture of the proximal interphalangeal (PIP) joint. A standard method for the flap design and a mathematical method to predict the advance distance have not been well established. In this study, we proposed a simplified method for the design of V–Y advancement flaps based on digital arteries and used a geometric model to predict the advance distance for the flexion contracture correction surgery. Methods According to the general concept of hand flap design and law of cosine, we proposed three principles in the design of the digital artery-based V–Y advancement flap that should be followed. Since 2021 to 2022, finger geometric data of 120 fingers (index, middle, ring, and small fingers) from 30 healthy participants were collected and analysed to evaluate the necessary advance distance and flap tip angle for PIP flexion contracture correction of different fingers by our flap design method. Results The middle finger needed a significantly longer advance distance compared to other fingers in the same degree flexion contracture correction. The ring finger had the largest length-to width ratio and smallest flap tip angle among the four fingers in the V–Y flap design. No vertical scar crossed the flexion creases and flap tip angle < 20° was found in the tentative V–Y flap design for the 120 fingers. Conclusions Our flap design method provides a proper advance distance and flap length-to-width ratio without common skin complications in the flap design for PIP flexion contracture of index, middle, ring and small fingers. This geometric model provides a mathematical basis for prediction of advance distance and flap tip angle in the design of a digital artery-based V–Y advancement flap.
