Consequences of chronic nasal obstruction on the laryngeal mucosa and voice quality of 4- to 12-year-old children.

Introduction: Dysphonia affects 6% to 23% of children, and chronic nasal obstruction may participate in its pathophysiology.

Objectives: To study the effects of chronic nasal obstruction on children's vocal quality.

Subjects And Methods: Two study groups were formed: nasal obstruction group (NOG), consisting of 60 children aged 4-12 years with important symptoms of chronic nasal obstruction; and a control group (CG), similar in gender and age range, consisting of healthy students without nasal, vocal, or auditory symptoms.
