Buteyko breathing plus smoking-hygiene for adolescents with passive household smoke exposure and chronic Eustachian tube dysfunction
Official title: Is There Efficacy of Adding Buteyko Breathing to Approach of Smoking Hygiene on Dysfucntion of Eustachian Tube and Lung Functions in Adolescnets Who Are Passively Exposed to Tobacco Smoke?
Run by Cairo University · NCT07236580 · Data updated 2026-11-12
This project will test whether adding regular Buteyko breathing exercises to smoking-hygiene education helps adolescents exposed to household tobacco smoke who have chronic Eustachian tube dysfunction and reduced lung function.

Is this trial a fit for you?
✓Likely a good fit
Adolescents with chronic obstructive Eustachian tube dysfunction who are passively exposed to tobacco smoke at home and whose parents provide consent are ideal candidates.
✕Probably not a fit
Patients with significant cardiac disease, chronic chest/lung disease, renal or hepatic disease, active smokers, or those unable to perform regular breathing exercises are unlikely to benefit or are excluded.

What this trial studies
This randomized interventional study will enroll 40 adolescents who are passively exposed to household tobacco smoke and who have chronic obstructive Eustachian tube dysfunction. Participants will be randomized 1:1 to two groups of 20; both groups receive a six-month smoking-hygiene program while the intervention group also performs 30-minute Buteyko breathing sessions six days per week for six months. Outcomes include objective measures of Eustachian tube function and pulmonary function tests, plus symptom scores and adherence. The trial is run at Cairo University with in-person enrollment and follow-up visits.
Why it matters
Potential benefit: If successful, adding Buteyko breathing could improve Eustachian tube function and lung function and reduce related symptoms in smoke-exposed adolescents.
How similar studies have gone: Breathing retraining approaches like Buteyko have shown modest benefits for asthma and respiratory symptoms in prior studies, but applying them to Eustachian tube dysfunction is novel and largely untested.
