Deconditioning mouth breathing through gymnastic exercises is indicated in which scenario?

• A. Hypertrophic Tonsils
• B. Absence of Obstruction in Nasopharyngeal Airways
• C. Presence of Obstruction in Nasopharyngeal Airways
• D. Nasal Polyps

Answer: (B)

Deconditioning mouth breathing with gymnastic exercises targets reestablishing nasal breathing and correct resting orofacial posture when the nasal airway is open. If the nasopharyngeal airway is unobstructed, nasal breathing is feasible, and the exercises can retrain tongue position, lip seal, and breathing pattern to prevent habitual mouth breathing. However, if there is obstruction—such as hypertrophic tonsils, adenoids, or nasal polyps—the underlying blockage must be addressed first, because exercises alone won’t overcome physical blockage and may not be effective. Therefore, this approach is indicated when there is no obstruction in the nasopharyngeal airways.
