Partial craniofacial duplication in a resource-limited setting: a case report.
Article in International journal of surgery case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction and importance: Diprosopus, or craniofacial duplication, is an extremely rare congenital malformation, representing only 0.4% of conjoined twins with an estimated prevalence of 1 in 15 million births. Fewer than 40 cases have been reported worldwide. We describe a case of partial craniofacial duplication in a child from rural Ethiopia, highlighting the challenges of delayed diagnosis and management in a resource-limited setting. Case presentation: A 7-year-old girl presented with a congenital mandibular mass that had remained untreated since birth due to a lack of antenatal care (ANC) and delayed health-seeking. Examination revealed a pedunculated soft tissue lesion containing duplicated rudimentary facial elements, including tooth-like structures and lip-like tissue. Laboratory investigations were normal, and skull radiography showed no bony abnormalities. Advanced imaging was not feasible. The mass was excised surgically, and gross and histopathological evaluation confirmed partial craniofacial duplication. Postoperative recovery was uneventful, with improved psychosocial outcomes. Clinical discussion: Unlike complete diprosopus, which is typically incompatible with life, partial forms may permit long-term survival. The embryopathogenesis remains debated, with proposed mechanisms including incomplete embryonic disc division and neural crest duplication. While management in well-resourced settings is often facilitated by advanced imaging and multidisciplinary planning, this case demonstrates that direct surgical excision can achieve favorable outcomes even where resources are limited. Conclusion: This rare case contributes to the limited literature on diprosopus and underscores the importance of strengthening ANC, anomaly screening, and community awareness. Timely surgical intervention, even in low-resource environments, can restore function and enhance psychosocial outcomes.
