STUDY OBJECTIVE The aim of this article was to identify the most common sites of obstruction in patients with obstructive sleep apnea (OSA) by a systematic review of published studies. DESIGN The review was conducted by a MEDLINE search of the English literature published during the years 1980 to 2002. The inclusion criteria were experiments involving five or more adult subjects, total rather than partial obstruction or narrowing of the upper airway, and techniques that were performed on the… 
Assessment of obstruction level and selection of patients for obstructive sleep apnoea surgery: an evidence-based approach
TLDR
Assessment of the different methods of investigating upper airway obstruction in patients with obstructive sleep apnoea finds that sleep nasendoscopy, acoustic reflectometry and pressure catheters can all provide useful information, and their use may be decided upon based on the experience and resources available in individual departments.
Role of sleep endoscopy in obstructive sleep apnea syndrome
TLDR
Evaluating level, degree and shape of obstruction of upper airway in patients with OSAS by sleep endoscopy and their relation to OSAS severity found all patients showed multisegmental levels of obstruction.
Comparison of full-night and ambulatory polysomnography with ApneaGraph in the subjects with obstructive sleep apnea syndrome
TLDR
It is suggested that ApneaGraph can be used as a screener for OSAS and it appears to be a more reliable device to confirm dominancy of palatal level obstruction.
Correlation between short-time and whole-night obstruction level tests for patients with obstructive sleep apnea.
TLDR
Evaluated the correlation between obstructive levels that were identified by a short-time and a whole-night test in patients with obstructive sleep apnea and found there are limitations of evaluating obstructive events that occur during a whole night with short- time tests.
Upper airway length may be associated with the severity of obstructive sleep apnea syndrome
TLDR
It is demonstrated that men with OSAS have longer UAL than women with OSas, independent of body size, which suggests that UAL may play a role in the pathophysiology of OSAS.
Association between Positional Dependency and Obstruction Site in Obstructive Sleep Apnea Syndrome
TLDR
Evidence is provided that positional dependent patients may have higher success rate of soft palate OSA surgery alone than non-positional dependent patients and although PD may be associated with obstruction site, PD only itself may not be useful in planning surgical treatment for OSAS.

TLDR
By understanding the rationale, indications, benefits, risks and success of the various treatment options available, clinicians will be able to make more informed treatment recommendations in patient management.
Diagnosis and Management of Obstructive Sleep Apnoea – A Literature Review
Review Article Timely diagnosis of obstructive sleep apnoea and its management is an important factor in terms of orthodontic treatment outcomes. Symptoms of obstructive sleep apnoea being suggestive
Diagnostic imaging and sleep medicine.
TLDR
Obstructive sleep apnea syndrome is a relatively common disorder characterized by recurrent episodes of upper airway collapse and obstruction during sleep that results in apneic events that lead to loud snoring, hypoxia, and arousals that interrupt the normal sleep cycle.
[The syndrome of increased upper airways resistance: What are the clinical features and diagnostic procedures?].
TLDR
The upper airway resistance syndrome "UARS" is a poorly defined entity, often described as a moderate variant of the obstructive sleep apnea syndrome, which predominantly affects non-obese young adults, with no predominance in either sex.

Site of Upper Airway Obstruction in Patients With Idiopathic Obstructive Sleep Apnea
TLDR
An interesting new method to locate the precise site of obstruction in patients with obstructive sleep apnea is described, which uses a thin catheter to measure inspiratory airflow pressures at various levels of the airway during sleep.

The site of obstruction in the upper aerodigestive tract in 20 snorers and/or patients with obstructive sleep apnea syndrome was determined by two methods: fiberoptic nasopharyngoscopy with the
Determination of obstructive site in obstructive Sleep Apnea
TLDR
Fifteen patients with proven OSA syndrome have subsequently undergone UPPP and other operations on the upper respiratory tract to relieve the obstruction associated with OSAS, and the present report examines the importance of proper evaluation of obstructive segment in OSAS.
Site of upper airway obstruction in obstructive apnoea and influence of sleep stage.
TLDR
Upper airway obstruction involves more than one specific site of the upper airway in the majority of sleep apnoea patients, and obstruction at lower levels of theupper airway is more likely to be observed during rapid eye movement sleep.
Localization of upper airway collapse during sleep in patients with obstructive sleep apnea.
TLDR
The effect of sleep position was evaluated in 10 patients and found to have little affect on the extent over which the UA collapsed during sleep independent of sleep state, and the effects of UPPP on regional UA collapse were evaluated in a small group of six patients.
Mechanics of the pharynx in patients with obstructive sleep apnea.
TLDR
A novel method for evaluating the location, closing pressure and compliance of collapsing segments in the passive pharyngeal airway of patients with OSA is described and it is speculated that a segment with a high closing pressure predisposes to airway narrowing during normal breathing during sleep.

TLDR
Since the effect of uvulopalatopharyngoplasty (UPPP) is best during the first few months after surgery, 10 patients were re-examined after only 3 months in order to record optimal results sequentially, and 6 still had obstructions involving the velopalatine segments and only 4 had none.
Anatomy of pharynx in patients with obstructive sleep apnea and in normal subjects.
TLDR
It is concluded that the passive pharynx is more narrow and collapsible in sleep-apneic patients than in matched controls and that velopharyngeal Pc is the principal correlate of the frequency of nocturnal desaturations.
Evaluation of the pharyngeal airway in patients with sleep apnea: value of ultrafast MR imaging.
TLDR
Ultrafast MR imaging is useful for localizing the sites of pharyngeal airway obstruction in patients with sleep apnea and to evaluate the usefulness of this technique for localization the site of obstruction.
