The research, led by Jessica Yavner and colleagues at the State University of New York Downstate Health Sciences University in Brooklyn, set out to answer a question that has lingered in surgical education circles: how do you implement a cost-effective, medical-student-driven simulation program that actually works? Simulation is widely used to build clinical skills, but the literature is surprisingly thin on practical guidance for programs that must run on shoestring budgets, particularly in institutions and regions with limited resources. The Brooklyn team designed a surgical skills simulation clerkship course with an annual budget of less than $1,000, a figure that would barely cover the cost of a single high-fidelity mannequin session at many training centers.

The curriculum focused on four pillars of early surgical competence: opening and closing procedures, relevant anatomy, and post-operative care. Rather than relying on expensive technology, the organizers embraced a near-peer teaching model in which medical students themselves delivered the instruction. This approach, well documented in the education literature, benefits both sides of the equation. Senior students consolidate their own knowledge by teaching, while junior students often find it easier to ask basic questions of a peer than of an attending surgeon. It also happens to be one of the most economical ways to scale skills training, since it requires no additional faculty time for every session.

Over one year, 230 students participated in the program. The researchers administered questionnaires before each session, immediately afterward, and again at three- and six-month follow-ups, measuring confidence and perceived benefit on Likert scales. Of the participants, 117 students completed paired pre- and post-session surveys, a response rate of 51.3 percent. The statistical analysis was appropriately rigorous for the design: Wilcoxon signed rank tests compared pre- and post-session confidence scores, Dunnett’s test assessed whether the gains were retained over time, and Spearman’s correlation examined how surgical interest and operating room exposure related to perceived benefit.

The results were striking in their breadth. Students reported significant improvements in median confidence from before to after the sessions across essentially every domain the curriculum touched: preparation for the operating room learning environment, suturing, knot-tying, laparoscopic anatomy, sterile and scrub technique, post-operative care, knowledge of laparoscopy, identification and handling of surgical instruments, respectful and safe behavior in the operating room, and operating room protocols. All of these improvements reached statistical significance at the p < 0.05 level. In other words, a few hours of low-cost, peer-delivered practice measurably changed how prepared students felt for nearly every dimension of the surgical environment that intimidates newcomers.

Just as important was what the follow-up surveys showed. Confidence gains were not confined to the immediate afterglow of a positive teaching session; the study assessed retention at three and six months, and the curriculum was found to effectively sustain student confidence over that period. Durability is the perennial weakness of short educational interventions, and many simulation programs struggle to demonstrate that their effects outlast the novelty of the experience. The Brooklyn team’s finding that the benefits persisted suggests the curriculum taught durable mental models, not just momentary reassurance.

The perceived value of the program was equally emphatic. 92.3 percent of students found the curriculum beneficial, and the degree of perceived benefit was positively correlated with surgical interest, with a Spearman correlation coefficient of 0.31 that was statistically significant. That modest but real association hints at a virtuous cycle that surgical educators care deeply about: students who arrive with an interest in surgery get the most out of hands-on simulation, and positive early experiences may, in turn, reinforce that interest at a formative stage of training. With surgical specialties facing persistent recruitment and pipeline challenges, interventions that strengthen the earliest encounters between students and the operating room carry implications well beyond a single clerkship.

The study’s emphasis on cost is what elevates it from a competent local program to a potentially exportable model. In a systematic review cited by the authors, researchers noted that cost is the missing outcome in simulation-based medical education research; most studies report learning gains without ever accounting for what those gains required in dollars, equipment, or faculty hours. High-fidelity simulators, virtual reality platforms, and cadaver laboratories all deliver value, but their price tags put them out of reach for many institutions, particularly in low- and middle-income countries and in under-resourced teaching hospitals. A curriculum that achieves significant, sustained confidence gains on an annual budget under $1,000 removes the most common objection to adopting simulation in exactly the settings where students may have the least prior exposure to operating rooms.

The institutional context adds weight to the findings. SUNY Downstate serves a diverse population in Brooklyn, and its medical students span a wide range of prior exposure to surgical environments. The study received ethical approval as an exempt protocol from the institutional review board, with a waiver of written informed consent, and the curriculum was funded by the institution’s Surgery Clerkship rather than by external grants, underscoring its lean operating model. The authors dedicated the work to Erfan Faridmoayer, whose contributions to the project they describe as an inspiring legacy, a reminder that behind every curriculum study is a community of educators and trainees who built it session by session.

For educators weighing whether a student-led simulation program is worth the logistical effort, the study offers a clear signal. It demonstrates that near-peer instruction, deliberately scoped content, and repeated measurement can produce statistically significant and durable gains in the specific competencies that make students feel ready for the operating room, all while minimizing the implementation barriers that typically sink such efforts. The next step for the field will be testing whether confidence gains translate into objectively measured technical performance and, ultimately, into safer and more productive student participation in real operations. But as a proof of concept, this Brooklyn experiment makes a compelling case that the most valuable surgical training does not always require the most expensive equipment; sometimes it requires little more than students willing to teach each other how to hold a needle driver.

The retrospective cohort study, led by Samir Faisal Yousif with colleagues Abdelsamie Abdalla Mohamed and Mohammed Yousof Bakhiet, drew patients from Soba University Hospital, Bahri Teaching Hospital, and Sharg al Neel Hospital. The team reviewed the records of every patient with an acquired lip defect who underwent reconstruction during the study window, excluding congenital cases, recurrent tumors, and incomplete files. The cohort skewed slightly male, with 53.3 percent of patients being men, and the average age was 43 years, with ages ranging from 6 to 80. That relatively young mean age, the authors note, likely reflects the burden of trauma among younger Sudanese patients, in contrast to series from other regions where older patients with skin cancers dominate the caseload.

The causes of tissue loss fell into a clear hierarchy. Tumor excision accounted for 58.3 percent of defects, making cancer the leading reason Sudanese patients needed their lips rebuilt. Of the 35 tumor-related cases, 29 involved squamous cell carcinoma and the remainder basal cell carcinoma, the two dominant malignancies of the lip worldwide. Trauma came second at 31.7 percent, a figure that included injuries such as gunshot wounds documented in the study’s clinical photographs. Infection caused 6.7 percent of defects, all attributable to cancrum oris, the devastating gangrenous disease also known as noma that remains endemic in parts of sub-Saharan Africa. Burns accounted for the final 3.3 percent. Interestingly, infection played a smaller role than in neighboring Ethiopia, where noma is a prominent cause of facial tissue loss, a difference the authors attribute to local epidemiology.

The anatomy of the defects followed predictable oncologic and traumatic patterns. The lower lip bore the brunt, affected in 55 percent of patients, because sun-exposed lower lips are the favored site of squamous cell carcinoma. Tumors showed a statistically significant predilection for the lower lip, while traumatic injuries distributed more evenly between upper and lower. Two-thirds of all defects were full-thickness, meaning they penetrated skin, muscle, and mucosa and destroyed the orbicularis oris sphincter that gives the lip its dynamic function. This depth matters enormously: a lip is not merely a cosmetic surface but a muscular valve, and reconstructing it means restoring coordinated muscle, sensation, and lining simultaneously. Notably, 26.7 percent of patients had defects spanning more than two-thirds of the lip, a proportion that signals late presentation and poses the hardest reconstructive challenges.

The surgical strategy followed the classic reconstructive ladder adapted to available resources. Defects involving less than one-third of the lip, which made up 58.3 percent of cases, were managed with primary closure in 25 percent of the cohort, full-thickness skin grafts in 10 percent, mucosal advancement flaps in 11.7 percent, and local flaps such as the Abbe and Estlander cross-lip procedures in the remainder. These techniques borrow tissue from the opposing lip or adjacent cheek, keeping the reconstruction within the specialized tissue of the oral region. For medium defects spanning one to two-thirds of the lip, surgeons turned to the Karapandzic flap, which rotates cheek tissue while preserving its nerve supply and blood supply, alongside the Abbe flap and a single nasolabial flap.

The largest defects demanded regional flaps harvested from distant parts of the body. The deltopectoral flap, raised from the chest wall, was used in 10 percent of patients, and the pectoralis major flap in 5 percent, often for massive defects with associated facial tissue loss. Free tissue transfer, in which a segment of tissue is detached with its blood vessels and reconnected microsurgically at the recipient site, was performed in only 3.3 percent of patients, and only when a mandibular defect required a free fibular flap. The authors are explicit about why: during the study period there was no microsurgical unit or routinely available microscope for free tissue transfer at the participating centers, so reconstruction proceeded with standard instruments and pedicled flaps whose blood supply remains attached at the donor site.

The outcomes tell a story of two very different patient populations. Overall, 78.3 percent of patients experienced no complications, with wound dehiscence at 8.3 percent, total flap necrosis at 3.3 percent, and partial flap loss at 3.4 percent as the main adverse events. Only four patients required revision surgery. Functionally, 80 percent of patients retained unaffected speech, and 75 percent maintained normal oral feeding and lip competence. Patient satisfaction reached 68 percent overall, climbing to 88 percent among those with defects smaller than one-third of the lip, and hitting 93 percent among patients treated with simple direct closure. These figures align closely with complication rates of 15 to 22 percent reported in both international series and other sub-Saharan African studies, suggesting that resource limitations did not compromise the fundamentals of care for smaller defects.

The statistical analysis sharpened the central finding. Early complications were significantly associated with larger defect size, with a Cramer’s V effect size of 0.49, a 95 percent confidence interval of 0.32 to 0.73, and a P value below 0.001, indicating a moderate to strong relationship. Patients with defects exceeding two-thirds of the lip showed high rates of poor oral competence and temporary loss of the oral seal, and dissatisfaction clustered overwhelmingly in this group, with 75 percent of dissatisfied patients belonging to the large-defect category. The deltopectoral flap, despite reliably providing bulk of tissue, produced no satisfied patients in this series, underscoring the aesthetic and functional trade-offs of pedicled chest flaps on the face. Comparable data from Egypt found that only 56 percent of patients with defects larger than two-thirds achieved full functional recovery, confirming that this is a global problem rather than a uniquely Sudanese one.

The authors frame these results as a call to action for surgical capacity building. Restricted access to specialized reconstructive services, limited microsurgical equipment, and delayed presentation driven by referral and socioeconomic barriers all conspired to push patients into the large-defect category, where outcomes deteriorate. Their recommendations are concrete: expanding microsurgical capability, strengthening surgical training, and improving resource allocation could shift large-defect reconstruction away from regional flaps toward free tissue transfer, which offers better contour, function, and satisfaction for extensive defects. They also acknowledge the limitations of their own work, including the small sample size, the retrospective design, the absence of validated satisfaction instruments, and a follow-up period confined to early outcomes at one month, since most patients did not return for long-term review once their wounds had healed.

What makes this study notable is its honesty about context. In high-resource centers, free flaps are used in more than 15 percent of lip reconstructions; in this Sudanese cohort, the figure was 3.3 percent, and even that was driven by jaw involvement rather than lip reconstruction itself. Yet the core message is not one of failure. For the majority of patients, whose defects were small and amenable to primary closure or local flaps, outcomes were indistinguishable from those reported in well-funded hospitals in India, Nigeria, and the United States. The study provides the first local evidence base for planning surgical services in Sudan, and it demonstrates that disciplined application of standard reconstructive principles can deliver functional lips and satisfied patients even where the microscope is absent. The challenge, the authors conclude, is ensuring that patients with the largest and most complex defects are not left behind by the limits of the system around them.
