Postoperative neurosensory impairment perception using ultrasonic BoneScalpel and conventional rotary instruments after bilateral split sagittal osteotomy.

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
purposeAlthough bilateral sagittal split osteotomy (BSSO) is the most widely used surgical technique for the correction of mandibular dentofacial anomalies, it is associated with lesion of inferior alveolar nerve (IAN) and unwanted neurosensory disorders. The aim of this study was to document the perception of changes in sensitivity and mean recovery time after BSSO, using an ultrasonic BoneScalpel versus the conventional rotary instruments. PATIENTS AND
methodsThis retrospective observational study included all patients with diagnosis of skeletal anomaly who underwent advancement or setback BSSO of less than 10 mL, using the ultrasonic osteotome or conventional rotary instruments. The patients were operated on at the Hospital Universitario Clínica San Rafael, Bogotá Colombia, between 2017 and 2018. The primary predictor variable was the osteotomy technique. The primary outcome was the presence or absence of postoperative sensory alteration, whereas secondary outcomes were time of appearance and recovery, affected anatomical region, laterality, and disturbance in daily activities. Data were analyzed using Chi-square, Mann-Whitney U, and Fisher's exact test.
resultsData of 38 patients were retrieved, of which 23 were operated with BoneScalpel and 13 with the conventional technique. Twenty patients were women and 18 were men. All patients reported experiencing at least one type of sensory disturbance immediately after the surgical procedure. There was a significant difference (p = 0.0001) in the time that the alteration was present between the two groups, in favor of the BoneScalpel group. The chin and the lower lip were the anatomical regions with the greatest alteration in sensitivity and persistence of it.
conclusionsThe results of this study indicate that BoneScalpel is effective in performing BSSO. They also suggest that it may reduce the occurrence of nerve damage during BSSO, although more research on this topic is required.
