A rare variant of oromandibular limb hypogenesis syndrome: a case report of glossopalatal ankylosis.

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: Oromandibular limb hypogenesis syndrome (OLHS) Type IIIA is an exceptionally rare congenital anomaly, with only a few cases documented in the literature. It is characterized by developmental hypoplasia of the tongue, mandible, and limbs, manifesting as hypoglossia, micrognathia, and hypomelia. Case presentation: We report the case of a 9-year-old patient presenting with restricted mouth opening and feeding difficulties. Clinical examination revealed fusion of the tongue to the palate with synechia. Surgical intervention involved the release of the dense fibrous band between the tongue and palate, followed by palatoplasty to correct the cleft palate. The cleft palate was successfully repaired using the Von Langenbeck technique, restoring oral functionality. Conclusion: This case highlights the clinical manifestations, differential diagnosis, and surgical management of OLHS Type IIIA. It underscores the importance of timely intervention to improve functional outcomes in patients with this rare syndrome.
