Buteyko Breathing and Approach of Smoking Hygiene: Effects on Dysfucntion of Eustachian Tube and Lung Functions

November 15, 2025 updated by: Ali Mohamed Ali ismail, Cairo University

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?

adolescents are usually exposed to tobacco smoke passively. this can reduce their lung functions and negatively impact functions of Eustachian tube. The solution is to lower rates to tobacco exposure and use the support of Buteyko Breathing

Detailed Description

in this study, we will randolmly recruit 40 adolescents who are usually exposed to tobacco smoke passively in house from smoking parent or household members. these adolescents will complain chronic dysfunction of their Eustachian Tube (chronic obstructive dysfucntion) . adolescents will be catagorized to one of both groupsl, group I or group II (N=20 patient in the group). Both groups will receive smokinh hyeigne approach for 6 months. Group I will additionally receive Buteyko Breathing 30-minute apprach (this appraoch will be appleid by patients all days, except fridays, weekly for 6 months).
