Increased Demodex Density and Risk of Demodicosis After Septorhinoplasty: A Prospective Cohort Study.
Article in Dermatology practical & conceptual, 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
introductionDemodex mites reside in the hair follicles and sebaceous glands of the head and face. An increase in their population can lead to primary or secondary demodicosis. Septorhinoplasty is a frequently performed aesthetic surgical procedure that can cause various cutaneous complications in the facial area.
objectivesThis study aimed to investigate the density of Demodex mites and the prevalence of demodicosis following septorhinoplasty.
methodsA total of 40 patients (29 females, 11 males) scheduled for septorhinoplasty, with a mean age of 26.25±7.47 years, were evaluated for clinical findings of demodicosis before and at the third month after surgery. Demodex density was assessed using the standardized skin surface biopsy technique, a noninvasive method involving cyanoacrylate adhesive, and microscopic evaluation of samples taken from the bilateral cheeks and nose.
resultsA statistically significant increase was observed in the number of Demodex mites in the malar and nasal regions and in the prevalence of demodicosis following septorhinoplasty. Additionally, the frequency of seborrhea and pustules showed a significant rise. Symptoms related to demodicosis were found to appear around the 22nd postoperative day and persisted up to the third month.
conclusionsDemodicosis should be considered in the differential diagnosis of patients presenting with erythema, papules, and pustules in both the early and late postoperative periods following septorhinoplasty, and necessary diagnostic investigations should be performed. Further large-scale studies with a greater number of patients are required to support our findings.
