    Obstructive sleep apnea syndrome (OSAS) involves airway narrowing due to muscular hypotonia and anatomical issues. This study found significant upper airway compromise in all evaluated OSAS patients, often at multiple sites.

    Area of Science:

    • Sleep Medicine
    • Otolaryngology
    • Respiratory Medicine

    Background:

    • Obstructive sleep apnea syndrome (OSAS) pathogenesis is linked to muscular hypotonia and upper airway anatomical abnormalities.
    • Understanding specific sites of airway compromise is crucial for effective OSAS management.

    Purpose of the Study:

    • To identify potential sites of upper airway obstruction in patients diagnosed with OSAS.
    • To evaluate the extent and location of airway narrowing in individuals with OSAS.

    Main Methods:

    • Evaluation of the upper airways in 25 patients diagnosed with OSAS.
    • Assessment for anatomical abnormalities contributing to airway compromise.

    Main Results:

    • Significant upper airway compromise was identified in all 25 patients studied.

  • Multiple sites of airway narrowing were observed in a subset of the patients.

    • Conclusions:

    • Anatomical abnormalities and airway narrowing are prevalent in OSAS patients.
    • Identifying multiple obstruction sites is important for understanding OSAS severity and treatment.
