The Upper Airway Resistance Syndrome: Oral Appliances

Oral Appliances Oral appliances that advance the mandible and tongue are already used to treat OSAS. These devices hold promise for treating UARS because of good patient acceptance and low morbidity, but, unfortunately, there are almost no data available to support their use. Loube et al reported a well-documented case of a 40-year-old man with […]

The Upper Airway Resistance Syndrome: Surgical interventions

Newman and colleagues published a prospective evaluation of surgical intervention in patients presenting over a 1-year period with snoring and EDS; only patients with Pes nadirs < —10 cm H2O and RDIs of < 5 were included. All nine patients reportedly opted for surgical interventions, including septoplasty with turbinate reduction, LAUP, UPPP, mandibular osteotomy with tongue advancement, […]

The Upper Airway Resistance Syndrome: Surgery

Rauscher and colleagues also studied nCPAP in nonapneic snorers, defined as patients with EDS and an AHI of < 5. These patients had a mean (± SD) 3- to 15-s EEG arousal index of 20 ± 10/h. Therefore, this was a more homogeneous population, and many of them likely had UARS, although, again, no invasive […]

The Upper Airway Resistance Syndrome: Treatment

CPAP, surgery, oral appliances, and weight loss are all viable treatment modalities for UARS, and they have received more recent attention in the literature. Unfortunately, the data regarding compliance, efficacy, safety, or a combination of these factors are lacking in many cases. natural asthma treatment CPAP In 1991, Guilleminault et al showed that in a […]

The Upper Airway Resistance Syndrome: Hypertension

Guilleminault et al reported similar results in 110 patients known to have UARS. In these patients, systolic and diastolic BP increased during the breaths associated with the arousal when compared to the BP measures that directly preceded the arousal. The systolic and diastolic BP also increased significantly during segments of labored breathing without the arousal […]

The Upper Airway Resistance Syndrome: Sequelae and Associated Disorders

Daytime Somnolence By definition, daytime somnolence is a component of UARS and may be as severe as that found in OSAS. Guilleminault et al first demonstrated significant daytime somnolence by the MSLT and Wilkinson addition test scores, as well as behavioral abnormalities from UARS in a population of nonap-neic/nonhypopneic snoring children. These daytime sequelae were […]

The Upper Airway Resistance Syndrome: Upper airway impedance

Ruhle and colleagues suggested in a recent review that upper airway impedance measurements using the forced oscillation technique may be useful as a surrogate of Pes in the diagnosis of UARS. With this technique, an airflow of 2 L/min is applied to a conventional nCPAP mask at an oscillatory frequency of 20 Hz. The researchers […]
