No full textThe role of structured training in learning microsurgery: a narrative review
No full textBackground and introduction. Microsurgery has transformed reconstructive surgery, offering superior aesthetic and functional outcomes, particularly in complex cases. Mastery of microsurgery is challenging due to the intricate nature of procedures and the precision required, leading to a steep learning curve. Various training methods, including traditional animal models and emerging synthetic alternatives, have been developed to enhance skill acquisition. Structured training programs, supported by national and international societies, are crucial for improving competency, with emphasis on both objective and subjective measures of performance.
Material and methods. This review utilized the PubMed database to analyze literature on microsurgery training, employing search terms like “Microsurgery” AND “training resident”. After systematic filtering, 15 relevant articles were included, encompassing studies evaluating improvements in anastomosis time and patency rates, along with resident confidence.
Results. Key findings included a 2022 study revealing a 41% patency rate among 1.792 anastomoses performed by residents after a 7-month training course with Wistar rats. Training duration significantly influenced performance. A virtual training program in low-resource settings demonstrated improved confidence in microsurgical skills, although statistical significance was limited by sample size. An Italian study indicated that structured long-term training led to significant improvements in Global Rating Scale (GRS) scores and reduced procedure times.
Discussion and conclusions. The findings emphasize the effectiveness of structured, hands-on training in enhancing microsurgical skills. While remote training offers valuable introductory knowledge, in-person practice remains essential for developing the precision required in microsurgery. An integrated training approach combining both methods could improve global access to microsurgical education, equipping practitioners with necessary skills for success in the field. Overall, structured training enhances residents’ confidence and technical competence
Toward Circularly Polarized Luminescence from Inherently Chiral Inverted Singlet–Triplet Chromophores
No full textRecent years have seen rising interest in molecules that violate Hund's rule, where the first excited singlet state lies below the triplet (Delta E ST < 0), accelerating reverse intersystem crossing, a key process in thermally activated delayed fluorescence. We present a computational study on such inverted singlet-triplet (IST) molecules modified for chirality to enable Circularly Polarized Luminescence (CPL), an unexplored direction for IST emitters. Two main chromophores, triangulene and pentalene, were functionalized with minimal chiral groups, preserving negative Delta E ST , as demonstrated via multiconfigurational calculations. We also explored inherently chiral, nonplanar chromophores, focusing on extended triangulenes resembling helicenes. Substituents enabling enantiomer separation were introduced, and racemization barriers were assessed. When singlet-triplet inversion was lost, structures were further optimized, yielding a promising substrate combining a high racemization barrier, strong CPL, and inverted singlet-triplet energetics, making it suitable for CP-OLED applications
Levator alae nasi muscle V-Y island flap for nasal tip reconstruction
No full textNasal tip reconstruction can be very challenging. It requires close attention to skin texture, colour and thickness matching, with the respect of the nasal aesthetic units and symmetry. Flaps are usually preferred to skin grafts where possible. Based on different donor areas, various flaps have been described for reconstruction of this region. Here we present a new V-Y myocutaneous island flap based on the levator alae nasi muscle (LAN muscle) blood supply. This flap may represent an alternative to the nasalis myocutaneous sliding V-Y flap previously described by Rybka. As its pivot point it is located more cranially than the nasalis flap, and it can advance more medially than the Rybka flap, with the possibility of covering larger defects of the nasal tip area, up to 1.8 cm in diameter. Over the past 5 years, 24 patients received nasal tip reconstruction with this flap following the resection of basal cell carcinomas. Good tip projection was maintained, and the aesthetic outcome was satisfactory, with well healed scars. We recommend this technique as an alternative to other flaps for nasal tip defects, especially if paramedian
