Drug Induced Submental Ultrasound in Obstructive Sleep Apnea Patients

Obstructive Sleep Apnea

In this study, submental ultrasound during awake and simultaneous under Drug-induced sleep endoscopy is applied in the diagnostic workup of obstructive sleep apnea patients. The aim is to assess the tongue base thickness during awake and sleep with different head positions. By correlation with Drug-induced sleep endoscopy findings, more parameters could be used for evaluation and management of upper airway collapse in obstructive sleep apnea patients.

The Effect of Tooth Position During Orthodontic Treatment on the Apnea/ Hypopnea Index (AHI)

Obstructive Sleep ApneaOrthodontic Tooth Movement2 more

The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place. The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.

Cardiopulmonary Exercise Test in Patient With Obstructive Sleep Apnea

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) can be described as a condition characterized by repetitive obstruction of the upper airway resulting in oxygen desaturation and awakening from sleep, loud snoring, and increased daytime sleepiness . Many studies have shown that a link exists between OSA and cardiovascular disease, chronic heart failure ischemia, hypertension, obesity, and impaired glucose tolerance . A number of factors are likely to play role in development of clinical OSA syndrome (OSAS) ranging from upper airway anatomy to central respiratory control mechanisms. The pathophysiology of OSA is unclear and complex. Several previous studies have explored pulmonary function in the OSAS patients Interestingly, OSAS has been found to be highly correlated with lower airway obstruction, although it is originally defined as an upper airway disease

OSA in Children Referred for Adenotonsillectomy

Obstructive Sleep Apnea

In children with OSA (Obstructive sleep apnea) adenotonsillectomy is regarded as the first choice of treatment. Studies in recent years have shown that the procedure does not always have the expected effect. Children with OSA are at greater risk for complications from the procedure. There is disagreement regarding the need for sleep studies in children prior to surgery in order to verify an OSA diagnosis. Today less than 10% of these children have polysomnography (PSG). The main purpose of this study is to describe the prevalence of OSA among children referred for adenotonsillectomy. The investigators will also examine these children prior to and six months after surgery to assess their sleep pattern and quality of life. The project outcome aims to improve the precision and quality of diagnosis and the short and long term effects of treatment of children with OSA.

A total of 400 participants will be recruited: 200 patients with suspected OSAS will be recruited from the sleep clinic (OSAS group), 100 patients diagnosed with dizziness will be recruited from the ENT clinic (Dizziness group). In addition, 100 patients with no dizziness and no evidence for OSAS will be recruited from both the sleep clinic and the ENT clinic (controls). Informed consents will be completed by all participants. ). In order to assess the effect of treatment of OSAS on dizziness -patients with the diagnosis of OSAS will complete validated questionnaires regarding sleep, dizziness and eustachian tube function 3 months following initiation of treatment with CPAP
