A hidden risk factor for residual mouth breathing in children after adenotonsillectomy: airborne allergen sensitization.
Article in Sleep & breathing = Schlaf & Atmung, 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
backgroundMouth breathing (MB), a common manifestation of sleep-disordered breathing in children may induce craniofacial developmental abnormalities leading to adenoid facies. Although adenoidectomy and/or tonsillectomy (A&T) represents the primary therapeutic intervention, a substantial proportion of pediatric patients exhibit residual mouth breathing postoperatively. Why a substantial subset of children exhibit residual MB remains a critical clinical question. Among the overlooked explanations for this incomplete recovery may be sensitization to airborne allergens-a hidden determinant of postoperative outcomes. This study sought to define the role of this under-investigated risk factor in the failure to resolve MB following A&T.
methodsA retrospective analysis was conducted on a cohort of children who underwent A&T at our hospital from June 2023 to June 2024. Incomplete lip seal during sleep was used as the diagnostic criterion for mouth breathing. Allergic rhinitis and rhinosinusitis symptoms were quantified using the Total Nasal Symptom Score (TNSS). Preoperative serum allergen screening was performed in all cases. Multivariate analyses were employed to assess associations between postoperative mouth breathing resolution and age, gender, BMI, allergen sensitization and TNSS.
resultsThe study included 502 children. Residual mouth breathing was observed in 39.44% of cases. Atopy to airborne allergens was significantly correlated with surgical outcomes (P = 0.028), with house dust mites (HDM) sensitization exerting particularly strong effects (P = 0.002). Elevated TNSS scores for both allergic rhinitis (correlation coefficient R = 0.249) and rhinosinusitis (correlation coefficient R = 0.290) predicted diminished therapeutic response.
conclusionSensitization to airborne allergens, particularly HDM, is significantly associated with adverse mouth breathing resolution following A&T, suggesting it as a hidden associated factor for residual mouth breathing.
