Reconstruction of microtia with crus helicis transversal deformity using flap technique combined with ear cartilage transplantation: a retrospective study.
Article in Maxillofacial plastic and reconstructive surgery, 2026. 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
backgroundThe combination of crus helicis transverse deformity and microtia presents one of the most complex ear deformities. Historically, the surgical correction of this deformity has predominantly utilized rib cartilage for ear reconstruction. This study presents a method for correcting microtia with crus helicis transversal deformity, utilizing the flap technique in conjunction with cartilage transplantation.
methodsFrom February 2017 to October 2023, a total of 42 patients with crus helicis transversal deformity and microtia were included in this retrospective study. The corrective surgery combines flap technique with cartilage transplantation. We collected the morphological data of ear, Visual Analogue Scale (VAS) satisfaction scores, and Aesthetic Outcomes Scale (AOS) aesthetic ratings of patients both prior to and 12 months following surgery.
resultsThe average duration of follow-up was 13.71 ± 2.97 months. Following the operation, there has been a significant improvement in the length, width, and circumference of the ear, as well as in the differences in these measurements between the two ears compared to prior to the procedure. The average AOS score prior to surgery was 17.90 ± 1.41, while the average AOS score following surgery increased to 29.57 ± 1.51. The preoperative VAS satisfaction score was recorded at 1.95 ± 1.12, while the postoperative VAS score showed a significant increase to 8.23 ± 0.87.
conclusionThe flap technique, combined with cartilage grafting, effectively corrects the crus helicis transversal deformity with microtia. The approach maximizes the use of deformity ear tissue while minimizing damage. Additionally, it creates a natural and aesthetically pleasing ear shape, resulting in high patient satisfaction.
