Upper Airway Resistance Syndrome

Upper Airway Resistance Syndrome (UARS) is a clinical condition caused disturbance of sleep quality by either snoring or resistance through the nasal and oral passages during sleep. Dr. Guillemenauit from Stanford University first described this syndrome in 1992. Some clinicians believe that UARS is a mild form of obstructive sleep apnea. Unlike sleep apnea, which occurs more frequently in males and obese patients, this condition occurs with equal frequency in either sex and is more prone to occur in patients with thin or normal body habitus. Patients with this condition may report excessive daytime sleepiness and fatigue.

This condition is usually diagnosed by an overnight polysomnogram and when suspected by the ordering clinician, an additional measurement of nasal airflow may be added to the study. Treatment options are similar to the therapies for with mild sleep apnea. These therapies include oral appliance therapy, weight loss (for patients who are overweight), and nasal CPAP. A successful trial of nasal CPAP helps confirm the diagnosis.
