Introduction:

Obstructive Sleep Apnea (OSA) is the total or partial limitation of the passage of air through the upper airways during sleep, it has two forms of presentation: central and obstructive ( related to the anatomical profile).

Objective:

to determine the relationship between the anatomical profile and severity of Obstructive Sleep Apnea in adult patients of a Private Clinic in Lima Norte, Lima, 2020-2022.

Methods:

Cross-sectional analytical study. Clinical records of patients diagnosed with OSA during 2020-2022 in a private clinic in Lima, Peru, were used. Our main variable was the severity of OSA, apnea-hypopnea index per hour (AHI), in addition, oxygen desaturation index (IDO), Epworth Scale, TC90%, body mass index (BMI), minimum saturation, and snoring. The response variable was OSA.

Results:

a total of 120 medical records were used. The predominant OSA was mild (29.2%), followed by very severe (26.7%). In very severe OSA; patients with retrognathia had a 3.0 higher frequency, those with a long face had a 30.0 lower frequency, and those with a short face had a 4.0 higher frequency compared to patients with a normal face (40 vs. 7 vs. 41 vs. 37; p< 0.01).

Conclusions:

OSA is associated with the anatomical profile. The ANGLE scale was the most associated with OSA compared to the Friedman Score. OSA was associated with BMI, IDO, minimum saturation, and maximum heart rate.
