Determining Morbidity of Adding Genioplasty to Bimaxillary Orthognathic Surgery.
Article in Aesthetic plastic surgery, 2023. 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
backgroundPatients with dentofacial anomalies may undergo orthognathic surgery to address functional and aesthetic concerns. Past works have evaluated determinants affecting length of stay (LOS) in patients undergoing upper and/or lower jaw surgery alone. No studies have assessed the addition of genioplasty to double-jaw (Lefort I, bilateral sagittal split osteotomy (BSSO))) surgery and its effect on LOS and other outcomes. This study investigates whether the addition of genioplasty incurs additional morbidity to patients undergoing complex orthognathic surgery.
methodsThis was a retrospective cohort study of patients undergoing orthognathic surgery at Yale-New Haven Hospital. Clinical and demographic information were compared across the "double"- and "triple"-jaw cohorts with t tests and Chi-squared analyses. Multivariable linear and logistic regression analyses were utilized to assess the impact of genioplasty when controlling for baseline patient differences.
resultsA total of 27 patients received Lefort I and BSSO (double-jaw), and 224 received Lefort I, BSSO, and genioplasty (triple-jaw). Six (22.2%) double-jaw patients were segmental and fifty-eight (25.9%) triple-jaw patients were segmental (p > 0.05), during the study period. Triple-jaw surgery was associated with increased operative time (+ 41.1 min, p < 0.01). There was no increase in LOS, postoperative nausea and vomiting, opioid use, hematoma, or infection (p > 0.05).
conclusionsThis study attempted to determine if triple-jaw surgery could influence patients' LOS and other surgical outcomes compared to double-jaw surgery. Only the operative time was significantly affected. This indicates that incorporation of a genioplasty can provide aesthetic benefit without incurring significant additional morbidity to the patient.
