    This study investigated sinus ventilation in 300 patients, revealing a surface-active substance in sinus secretions that may cause nasal and sinus obstruction.

    Area of Science:

    • Otolaryngology
    • Respiratory Physiology
    • Biochemistry

    Context:

    • Frontal and maxillary sinus pathologies affect sinonasal ventilation.
    • Understanding ostial resistance is crucial for diagnosing and treating sinus conditions.
    • Physiological conditions were simulated to accurately assess ventilatory dynamics.

    Purpose:

    • To differentiate naso-sinus and sino-nasal ventilatory ostial resistance.
    • To identify factors contributing to sinus obstruction.
    • To investigate the presence of a surface-active substance in sinus secretions.

    Summary:

    • A pressure chamber was used to measure ventilatory ostial resistance in 300 patients with frontal and maxillary sinus pathologies.
    • Analysis of obstruction factors before and after washout suggested a surface-active substance in sinus secretions.
