The Revision of Vertical Prolabial Deficiency in Bilateral Cleft Lip Patients: Prolabium Lengthening by Nasolabial Muscle Reconstruction.
Article in Aesthetic plastic 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
backgroundVertical prolabial deficiency is a common issue among a significant number of secondary bilateral cleft lip patients. Historically, the Abbé flap has been utilized to augment the volume of prolabial soft tissue. This article introduces an innovative surgical approach for prolabial lengthening through the reconstruction of the nasolabial muscle.
methodsFrom December 2017 to January 2023, 65 secondary bilateral cleft lip patients presenting with vertical prolabial deficiency underwent this novel surgical procedure. The nasolabial muscle was meticulously reconstructed and lengthened. The measurements were taken for the length of the philtrum, vermilion, and the lower facial region. Patient satisfaction regarding the labial morphology was assessed using a structured questionnaire.
resultsThe average philtrum length was 9.8 ± 2.2 mm preoperatively, which significantly increased to 13.5 ± 1.3 mm immediately post-surgery (P < 0.05). The average ratio of prolabial length to lower facial length was 0.32 ± 0.03 preoperatively, improving to 0.40 ± 0.04 postoperatively, with a follow-up period ranging from 6 months to 3 years (P < 0.05).
conclusionThe surgical technique described effectively lengthens the prolabium, thereby enhancing the aesthetic appearance of secondary bilateral cleft lip patients with vertical prolabial deficiency.
