1 · What the graph read from it

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.

2 · The registry

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

objectiveComplex mandibular anatomy including rolled-out inferior mandibular border, thin rami with cortically adherent inferior alveolar nerve (IAN) complicate the application of the current mandibular osteotomies. This study aims to introduce an intraoral Inverted-L Ramus Osteotomy (ILRO) modified with IAN lateralization and intra-canal osteotomy for management of complex mandibular anatomical variations during mandibular setback surgery. PATIENTS AND

methodsThis prospective study included 20 skeletal class III patients (mean age: 21.6 ± 3.3 years) with complex mandibular anatomy indicated for mandibular setback surgery (mean setback: 6.05 ± 1.1 mm). Preoperative CBCT imaging, digital planning, and fabrication of cutting / drilling guides were performed. Surgery involved mandibular setback through the application of the ILRO modified with nerve lateralization and intra-canal osteotomy. IAN function evaluated preoperatively at intervals up to one year postoperatively. Data on bad splits and surgical duration were also analyzed.

resultsThe mean surgical duration was 2.26 ± 0.21 h, with bilateral IAN exposure completed in 11 ± 3.2 min per side. All 40 osteotomy sites were separated without bad splits. Neurosensory deficits were observed in 90% of patients at two months, decreasing to 35% at six months and 5% at one year.

conclusionThe introduced osteotomy overcomes the limitations of the traditional mandibular osteotomies in dealing with mandibular complex anatomy with adequate IAN protection and split segments integrity during mandibular setback surgery. CLINICAL RELEVANCE: The introduced osteotomy provides a safe alternative to the current mandibular osteotomies utilized in mandibular setback surgery.
