Atlantoaxial Rotatory Fixation after Microtia Reconstruction Surgery.

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
Nontraumatic atlantoaxial rotatory fixation after microtia reconstruction surgery is a rare complication. Intraoperative cervical hyperextension and/or excessive rotation and postoperative inflammation have been reported as causes of atlantoaxial rotatory fixation. We herein describe cases of atlantoaxial rotatory fixation after microtia reconstruction surgery.
methodsThis was a retrospective study of 80 patients (165 surgeries) who underwent microtia reconstruction surgery in Dokkyo Medical University Hospital between April 2006 and December 2012. The patient- and operation-related variables were obtained from medical charts. Neck radiographs and computed tomography scans of patients with atlantoaxial rotatory fixation were evaluated to check for cervical spine abnormalities.
resultsFive cases of atlantoaxial rotatory fixation after microtia reconstruction surgery were recorded. Three of these five cases were diagnosed with Klippel-Feil syndrome after the onset of atlantoaxial rotatory fixation. No significant difference was found in the operative duration and other variables between patients with atlantoaxial rotatory fixation and those without. All patients immediately underwent conservative treatment and showed complete recovery and no recurrences.
conclusionsAlthough atlantoaxial rotatory fixation is a rare complication, surgeons should consider it in patients with neck problems following microtia reconstruction surgery. A patient with microtia may have unrecognized Klippel-Feil syndrome. Patients with Klippel-Feil syndrome are more likely to develop atlantoaxial rotatory fixation, which may have severe consequences. Thus, it is crucial to preoperatively identify Klippel-Feil syndrome with neck radiography and to detect atlantoaxial rotatory fixation at the earliest.
