Surgical Management of Dorsocervical Fibro-Lipodystrophy (Buffalo Hump): Systematic Review and Meta-Analysis.
Synthesis 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
backgroundDorsocervical fibro-lipodystrophy, commonly known as "buffalo hump," presents a challenging deformity often associated with HIV-related lipodystrophy or idiopathic etiologies. Although various surgical techniques have been reported, a comprehensive evaluation of their safety, efficacy, and recurrence rates remains lacking. This systematic review and meta-analysis aimed to evaluate outcomes of surgical interventions, particularly suction-assisted lipectomy, in managing dorsocervical fibro-lipodystrophy.
methodsA systematic review with meta-analysis was conducted using PubMed and ScienceDirect. Eligible studies reported surgical outcomes of dorsocervical fibro-lipodystrophy managed with suction-assisted or excisional lipectomy. Meta-analyses used a random-effects model, with heterogeneity and publication bias assessed. Sensitivity analysis was performed.
resultsTwenty-two studies encompassing 218 patients were included. Most cases were associated with HIV-related lipodystrophy, and the average patient age was 47.4 years. Suction-assisted lipectomy was the most common approach. The pooled recurrence rate with liposuction was 10.6%, and revision procedures occurred in 15.3% of cases. Following sensitivity analysis, recurrence and revision rates decreased to 1.4% and 1.3%, respectively, with minimal heterogeneity. The pooled recurrence rate after excisional lipectomy and hybrid techniques was 0%. Reported complications included seroma, hematoma, wound dehiscence, and bacteremia, with higher rates observed in excisional or hybrid approaches. Methodological quality varied, with most studies scoring moderately.
conclusionSuction-assisted lipectomy appears to be a safe and effective treatment for dorsocervical fibro-lipodystrophy, especially when performed with meticulous technique. However, the overall low quality of evidence underscores the need for prospective studies to optimize management strategies.
