Assessment of facial asymmetry in patients with orofacial cleft based on the biometric proposal of the average male face.
Article in Clinical oral investigations, 2025. 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
objectivesThe aim of this study was to determine the location and severity of facial soft tissue deformities in patients with orofacial cleft prior to orthognathic surgery. MATERIALS AND
methodsLinear measurements were performed on 30 scans of male faces without cleft and 10 faces with cleft. Three-dimensional (3D) coordinates of anthropometric points were used to calculate an Asymmetry Index for each point. An average male face was generated from the 30 unaffected scans using GOM Inspect Suite 2000 software. By superimposing cleft faces onto the Assessment of facial asymmetry in patients with orofacial cleft based on biometric proposal of the average male face, the location and severity of deformities were visualised in the x, y, and z axes. Statistical analysis of linear measurements and Asymmetry Index values was performed using a Z-score, with significance determined by the p-value.
resultsCompared to controls, patients with orofacial clefts had a shorter and narrower face, a wider nose, and narrower lips. The Asymmetry Index identified the nose, upper lip, and chin as the regions with the most asymmetry. A significant deficiency of soft tissues in the oronasal area was observed, especially on the side affected by cleft.
conclusions3D analysis enables precise localisation and quantification of soft tissue asymmetry in cleft patients. This method highlights the specific regions most affected by deformities and confirms the clinical applicability of 3D facial scanning. However, the relatively small sample size (10 males with clefts and 30 controls) and the exclusion of females limit the generalisability of these findings and should be addressed in future studies. CLINICAL RELEVANCE: 3D scanning represents a valuable visual tool for assessing residual deformities related to clefts. Provides objective data that can improve surgical planning and individualised treatment strategies for patients undergoing orthognathic procedures.
