Abstract
INTRODUCTION Increased pharyngeal collapsibility leads to obstructive sleep apnea (OSA). Positive airway pressure titration during drug-induced sleep endoscopy (DISE-PAP) provides objective collapsibility metrics, the pharyngeal opening pressure (PhOP), and active pharyngeal critical pressure (PcritA ). We examined the interrelationships between risk factors of OSA, airway collapsibility measures, and clinical manifestations of the disease. METHODS This is a cross-sectional analysis of consecutive OSA patients undergoing DISE-PAP. Nasal PAP was increased stepwise until inspiratory flow limitation was abolished, signifying PhOP. PcritA was derived from the resulting titration pressure-flow relationships. Clinical data including demographics, anthropometrics, sleep studies, and patient-symptom questionnaires were obtained from the electronic medical record. Multivariate regression was used to evaluate the relationship between risk factors, airway collapsibility, and clinical data. RESULTS On average, the 164 patients meeting inclusion criteria were middle-aged (54.2 ± 14.7 years), overweight/obese (BMI 29.9 ± 4.5 kg/m2 ), male (72.6%), White (79.3%) and had severe OSA (AHI 32.0 ± 20.5 events/hour). Mean PhOP was 7.5 ± 3.3 cm H2 O and mean PcritA was 0.80 ± 3.70 cm H2 O. Younger age (Standardized β = -0.191, p = 0.015) and higher BMI (Standardized β = 0.176, p = 0.028) were associated with higher PhOP, but not PcritA . PhOP and PcritA were both associated with AHI, supine AHI, and SpO2 nadir. Higher PhOP was associated with higher snoring scores (Standardized β = 0.246, p = 0.008), but not other patient-reported outcomes. CONCLUSION Objective assessment of passive and active airway mechanics during DISE relates with clinical risk factors for OSA. Quantitative measures of collapsibility provide accessible and meaningful data, enhancing the standard sleep surgery evaluation. LEVEL OF EVIDENCE 4 Laryngoscope, 134:1978-1985, 2024.

Abstract
INTRODUCTION The significance of hyoid dynamics in OSA pathophysiology remains unclear. Drug-induced sleep endoscopy (DISE) is often used for evaluating patients intolerant to positive airway pressure (PAP) therapy. We performed DISE with concurrent hyoid-focused ultrasonography to quantify hyoid dynamics during obstructive and non-obstructive breathing. METHODS A cross-sectional analysis from a prospective cohort of patients undergoing DISE with PAP titration (DISE-PAP) and hyoid-focused ultrasound was conducted. Hyoid ultrasound was performed during obstructive breathing, and non-obstructive breathing after PAP administration. Motion was quantified by generating displacement curves based on echo-tracking hyoid movement. The image analysis protocol for quantifying hyoid displacement was performed independently by two researchers, and reliability of measures was assessed. Univariate and multivariate regressions were performed for various clinical data and hyoid displacement during obstructive breathing. RESULTS Twenty patients met inclusion criteria. On average, the cohort was male (75%), elderly (65.9 ± 10 years), overweight (29.3 ± 3.99 kg/m2 ), and with moderate-to-severe OSA (29.3 ± 12.5 events/h). Mean hyoid displacement during obstructive breathing was 5.81 mm (±3.48). In all patients, hyoid displacement decreased after PAP administration (-3.94 mm [95% CI: -5.10, -2.78]; p < 0.0001). Inter-rater reliability for measures of hyoid displacement was excellent. After multivariate regression, hyoid displacement at baseline was associated with higher AHI (β [95% CI] = 0.18 [0.03, 0.33], p = 0.020). CONCLUSION During DISE, hyoid displacement is greater during obstructive breathing with significant variability amongst patients. Further, these ultrasonographic measurements had excellent intra- and inter-rater reliability. Additional, larger studies are needed to understand contributors to hyoid mobility.

Abstract
Obstructive sleep apnea is a sleep disorder with a high prevalence in the world population. The mandibular advancement device is one of the options for treating obstructive sleep apnea. Neck computed tomography and drug-induced sleep endoscopy are complementary diagnostic tests that may help predict the effectiveness of mandibular advancement devices. This study aims to analyze the best method for predicting the effectiveness of mandibular advancement devices in the therapeutic approach to obstructive sleep apnea. PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science Core Collection databases will be comprehensively searched. We will include randomized clinical trials, non-randomized prospective or retrospective clinical studies, case controls, cohort studies, and case series. Two authors will independently conduct data extraction and assess the literature quality of the studies. The analysis of the included literature will be conducted by Revman 5.3 software. The outcomes that will be analyzed are craniofacial characteristics, cephalometric assessments, site and type of obstruction of the upper airway, mean values of the apnea-hypopnea index, and SaO2 verified in the initial and follow-up polysomnography. This study will provide reliable, evidence-based support for the clinical application of mandibular advancement devices for obstructive sleep apnea.

Abstract
OBJECTIVE To examine the accuracy and interrater reliability of a visually assessed vs airflow-based measure of pharyngeal collapsibility obtained in patients with obstructive sleep apnea undergoing drug-induced sleep endoscopy (DISE). STUDY DESIGN Prospective observational study. SETTING Academic tertiary care practice. METHODS Patients underwent DISE with airflow monitoring and nasal positive airway pressure titration to determine visual and airflow-based levels of pharyngeal opening pressure (PhOP). Visual DISE-PhOP was assessed by 2 blinded independent raters and defined as the pressure at which visual confirmation of airway collapse, including snoring, was abolished. Airflow-based DISE-PhOP was defined as the minimally effective positive airway pressure that abolished inspiratory flow limitation. Equivalence testing between visual and airflow DISE-PhOP of each rater was performed with the two one sided T-test (TOST) with an a priori equivalence bound of ±1 cm H2 O. Interrater reliability was evaluated with the intraclass correlation coefficient. RESULTS One hundred patients were enrolled in the study and 77 completed the full evaluation. The population was predominantly male (74%) with an average age of 54.8 years, body mass index of 30.1 kg/m2 , and apnea-hypopnea index of 30.7 events/h. Equivalence testing showed that both raters were within ±1 cm H2 O of airflow-based DISE-PhOP (-0.43 to 0.09 cm H2 O and -0.32 to 0.48 cm H2 O). Interrater reliability of visual DISE-PhOP between the raters was also good to excellent with an intraclass correlation coefficient of 0.895 (95% CI, 0.84-0.932). CONCLUSION DISE-PhOP, a measure of upper airway collapsibility, was equivalent between airflow-based and visual assessments with strong interrater reliability, supporting its adoption as a standardized objective parameter in clinical DISE.

Abstract
OBJECTIVE To develop an expert consensus statement regarding persistent pediatric obstructive sleep apnea (OSA) focused on quality improvement and clarification of controversies. Persistent OSA was defined as OSA after adenotonsillectomy or OSA after tonsillectomy when adenoids are not enlarged. METHODS An expert panel of clinicians, nominated by stakeholder organizations, used the published consensus statement methodology from the American Academy of Otolaryngology-Head and Neck Surgery to develop statements for a target population of children aged 2-18 years. A medical librarian systematically searched the literature used as a basis for the clinical statements. A modified Delphi method was used to distill expert opinion and compose statements that met a standardized definition of consensus. Duplicate statements were combined prior to the final Delphi survey. RESULTS After 3 iterative Delphi surveys, 34 statements met the criteria for consensus, while 18 statements did not. The clinical statements were grouped into 7 categories: general, patient assessment, management of patients with obesity, medical management, drug-induced sleep endoscopy, surgical management, and postoperative care. CONCLUSION The panel reached a consensus for 34 statements related to the assessment, management and postoperative care of children with persistent OSA. These statements can be used to establish care algorithms, improve clinical care, and identify areas that would benefit from future research.

Abstract
Objective To further demonstrate sleep endoscopy's utility in improving surgical outcomes for pediatric OSA. Methods This is a retrospective review of surgically naïve patients <18 years old with diagnosed moderate-severe OSA who underwent DISE at the time of initial sleep surgery. Patients included in final analysis had both preoperative and postoperative polysomnograms. Surgical success was defined as an oAHI decrease by at least one diagnostic category. Residual OSA was defined as any patient with postoperative oAHI >1. Results A total of 106 patients had preoperative and postoperative polysomnograms. Patients with comorbidities comprised 53.8% of the group. Average BMI% was 88.2, with 75.5% classified as obese. The most common area of collapse was the base of tongue, occurring in 32.1% of patients. There was a statistically significant decrease from the mean preoperative oAHI of 29.7 to the mean postoperative oAHI of 6.6 (p < 0.001). Surgical success occurred in 76.4% of patients. A postoperative oAHI of <5 was achieved in 57.7% of patients with moderate or severe OSA. The average BMI% of patients who met surgical success was 86.4, while the average BMI% of patients who did not was 90.8. A postoperative oAHI of <5 was achieved in 68.4% of patients with a BMI% < 85, compared with 55.2% of patients with a BMI% ≥ 85. Conclusion This study supports the utilization of DISE during initial surgery for severe sleep apnea in the pediatric population. It was found to effectively aid in significantly reducing surgically naïve patients' mean oAHI. Level of Evidence Level III.

Abstract
OBJECTIVE To describe the technique and determine the indications for sleep endoscopy in children. MATERIAL AND METHODS This study included 35 children, the average age of 5 years 1 month ± 3 years 4 months (from 1 year 6 months to 14 years 5 months). All children underwent standard polysomnography and sleep endoscopy. RESULTS According to polysomnography, severe obstructive sleep apnea (OSA) was diagnosed in 21 children, moderate - in 8 children and mild - in 6 children. Sleep endoscopy revealed that in most cases in unoperated children (about 70%), adenoids and palatine tonsils were the cause of obstruction. In the group of children, who previously underwent surgery for OSA, the causes of residual apnea more often were soft palate and palatine tonsils. In 5 of 8 children, tonsils pharyngoscopy size did not exceed the 1st degree. In 1 child after adenotonsillectomy, the hypertrophic tori tubarii were the cause of obstruction. Another rare cause of upper airway obstruction, lingual tonsil hypertrophy, was found in 2 primary patients. CONCLUSION Sleep endoscopy is a safe and useful method that makes it possible to determine the level of obstruction in children and to plan the optimal amount of surgical treatment.

Abstract
OBJECTIVE To observe the degree of airway collapse at varying levels of continuous positive airway pressure (CPAP) during drug pediatric induced sleep endoscopy. METHODS Using our institutional anesthesia protocol for pediatric DISE procedures, patients were anesthetized followed by evaluation of the nasal airway, nasopharynx, velum, hypopharynx, arytenoids, tongue base, and epiglottis. CPAP titration was performed under vision to evaluate the degree of airway collapse at the level of the velum. Comparison was made with pre-operative polysomnography findings. RESULTS Twelve pediatric patients underwent DISE with intraoperative CPAP titration. In 7/12 patients, DISE observed CPAP titration was beneficial in elucidating areas of obstruction that were observed at pressures beyond those recommended during preoperative sleep study titrations. In 3 patients, DISE observations provided a basis for evaluation in children not compliant with sleep study CPAP titration testing. With regard to regions effected, airway collapse was observed at the velum and oropharynx to a greater degree when compared with the tongue base and epiglottis. CONCLUSION DISE evaluation of the pediatric patient with obstructive sleep apnea may present a source for further patient evaluation with respect to CPAP optimization and severity of OSA assessment, particularly in syndromic patients.

Abstract
OBJECTIVE Obstructive Sleep Apnea (OSA) in children is treated primarily with adenotonsillectomy (AT). When clinical exam demonstrates small tonsils, the success of AT in resolving OSA is uncertain. The purpose of this study is to determine the utility of Drug induced Sleep Endoscopy (DISE) for children with OSA and small tonsils (Brodsky scale 1+) and to identify what obstructive trends exist in this subset of patients and to determine the utility of DISE-directed surgical intervention in patients with small tonsils. METHODS A retrospective chart review was performed for patients who underwent DISE at a tertiary care center over a 2-year period. Inclusion criteria were 1+ tonsils and a positive sleep study. Data collected included DISE findings, BMI, comorbid conditions, and pre-op PSG data. RESULTS Forty children were included with a mean age of 5.0 years (range 8 months-16 years). Mean preoperative AHI was 5.46 and mean oxygen saturation nadir was 87.1%. The most common contributor to airway obstruction was the adenoid (29 patients, 72.5%), followed by the tongue base or lingual tonsil (21 patients, 52.5%). The palatine tonsils (10 patients, 25.0%), epiglottis (10.0%), or obstruction intrinsic to the larynx (10.0%) were significantly less frequently identified as contributors to OSA when compared to the adenoid (P < .001). The majority of patients had multilevel obstruction (25 patients, 62.5%). Adenoidectomy (27 patients, 67.5%) was the most commonly performed procedure, followed by tonsillectomy (10 patients, 25.0%, P < .001) and tongue base surgery (9 patient 22.5%, P < .001). CONCLUSION In this group, small palatine tonsils were infrequently identified as a contributor to airway obstruction and tonsillectomy was avoided in most cases. This study illustrates the utility of DISE as a tool to personalize the surgical management of pediatric patients with OSA and small tonsils on physical exam.

Abstract
The presence of complete concentric collapse of the soft palate (CCCp) during drug-induced sleep endoscopy (DISE) has important therapeutic consequences. However, CCCp may present in various, sometimes doubtful, ways due to the complex anatomy of the upper airway. Herein, we aimed to characterize these doubtful variants by reviewing the DISE recordings of patients with obstructive sleep apnea (n = 332). We observed in some individuals that the soft palate collapsed in an anteroposterior-laterolateral (AP-LL) way, producing a polygonal shape that was distinct from CCCp. Patients with this collapse pattern (n = 29) had a smaller neck circumference and less severe obstructive sleep apnea than patients with CCCp (n = 68). The majority of patients with AP-LL collapse (n = 19) were originally diagnosed with CCCp. Based on these findings, AP-LL collapse of the soft palate might represent a distinct DISE phenotype that is easily confounded with CCCp.

Abstract
Background The Friedman staging is a classic system to predict outcomes of obstructive sleep apnea (OSA) surgery. Increasing stage indicates more severe upper airway (UA) obstruction and worse surgical successful rate. In previous studies, the UA obstruction between stages were usually assessed based on awake examination. Drug-induced sleep endoscopy (DISE) is a new method that can evaluate airway collapse characteristics during sleep. Therefore, we planned to compare Friedman staging and DISE findings and fulfill the knowledge gap on the correlation between awake and sedated UA examination. Methods Retrospective case series study that assessed patients with OSA who underwent DISE. Subjects were classified to stage II and stage III groups based on Friedman staging system. UA collapse characteristics based on velum, oropharynx, tongue base, epiglottis (VOTE) classification, including single/multiple obstruction sites, single/combined upper and lower obstruction levels, collapse degree and patterns in different sites, and surgical results among the groups were analyzed. Results A total of 175 cases were analyzed. No significant differences were found in baseline measurements between groups. Stage III patients (n=102) had a higher proportion (74.5%) with 3 or 4 obstruction sites than stage II (57.5%, n=73). Velum (V) + oropharynx (O) + tongue base (T) was the most common multi-sites combined obstruction pattern with 33% in stage II and 37% in stage III, isolated lower level obstruction was the least with 6% and 4%, respectively. No significant differences were found in obstruction sites and levels. 106 patients underwent surgeries and 33 had post-surgical sleep study, 73.7% and 63.6% response rate were found in stage II and III with no significant difference. Conclusions Upper and lower combined obstruction was the main pattern of collapse in both, Friedman stage II and III patients. Patients with OSA and Friedman stage III had more than 2 sites of obstruction than stage II patients.

Abstract
OBJECTIVE Positional obstructive sleep apnea (POSA)-defined as obstructive sleep apnea twice as severe supine than nonsupine-may offer clues to the underlying pattern of upper airway collapse in children. We compared drug-induced sleep endoscopy (DISE) findings in children with and without POSA. We hypothesized that children with POSA would have significantly higher obstruction at the gravity-dependent palate and tongue base but not at the adenoid, lateral wall, or supraglottis. STUDY DESIGN Retrospective case series. SETTING Tertiary pediatric hospital. SUBJECTS AND METHODS We included children aged 1 to 12 years with obstructive sleep apnea diagnosed by polysomnography who underwent DISE from July 2014 to February 2019. Scores were dichotomized as ≥50% obstruction (Chan-Parikh 2 or 3) vs <50% obstruction (Chan-Parikh 0 or 1). RESULTS Of 99 children included, 32 (32%) had POSA and 67 (68%) did not. Children with POSA did not differ from children without POSA in age, overall apnea-hypopnea index, sex, race, syndromic diagnoses, obesity, or history of adenotonsillectomy. In logistic regression models, odds of ≥50% obstruction were significantly higher at the tongue base (odds ratio, 2.77; 95% CI, 1.04-7.39) after adjustment for age, sex, obesity, previous adenotonsillectomy, and syndrome. No difference was noted at the adenoid, velum, lateral wall, or supraglottis. CONCLUSION POSA was associated with higher odds of obstruction on DISE at the tongue base but not at other levels.

Abstract
PURPOSE Identification of upper airway (UA) obstruction based on pharyngeal factors is important for obstructive sleep apnea (OSA) evaluation. This study is to assess the association between UA collapse characteristics and Friedman tongue position (FTP) in patients with OSA through drug-induced sleep endoscopy (DISE). PATIENTS AND METHODS Retrospective study in individuals with OSA who were intolerant to continuous positive airway pressure (CPAP) treatment, submitted to DISE between June 1, 2013, and July 31, 2017. All subjects were classified as having an FTP grade of I to IV, and the velum, oropharynx, tongue base, epiglottis (VOTE) classification was used to analyze the DISE findings. UA collapse characteristics by DISE and FTP grading were compared between groups. The associations between specific DISE findings and FTP were analyzed. RESULTS In total, 205 patients were assessed. A positive and significant correlation was identified between the presence of retropalatal complete concentric collapse (CCC) and FTP grade, according to the following distributions: I, 17.4%; II, 22.9%; III, 33.7%; and IV, 48.7% (P = 0.014). A logistic regression model revealed that CCC was associated with FTP grade IV. After adjusting for age, sex, body mass index (BMI), and tonsil size (TS), the grade IV individuals had a 4.4-fold higher risk of having CCC than grade I individuals (P = 0.026). Multiple collapse sites and palatopharyngeal or combined (palatopharyngeal and hypopharyngeal) collapse were more prevalent in grade IV individuals. CONCLUSION OSA patients intolerant to CPAP have a strong positive correlation between the FTP grade and presence of retropalatal CCC. FTP grade IV is an independent risk factor for velum-CCC, controlling for sex, age, BMI, and TS grade.

Abstract
Objective Obstructive sleep apnoea hypopnoea syndrome associated with obesity poses major perioperative airway challenge. Drug-induced sleep endoscopy (DISE), is a real-time upper airway flexible fiberoptic nasoendoscopy in awake and sedation/anaesthesia-induced sleep. The aim of current study was to assess the correlation of bedside airway screening tests with level of obstruction during DISE. Methods Study was performed in endoscopy suite. Parameters calculated in 40 study group patients were Berlin questionnaire responses, Apnea hypopnea index (AHI), interincisor distance, Mallampati classification (MPC), neck circumference (NC), thyromental distance (TMD), NC/TMD ratio, sternomental distance (SMD), upper lip bite test, lateral cephalometry derived gonial angle and mentohyoid distance (MHD), Muller’s manoeuvre during awake nasoendoscopy, Croft–Pringle grade of airway obstruction during DISE and effect of jaw thrust. Results All patients were American Society of Anesthesiologists physical status 1 and 2 with AHI > 30. Positive responses to Berlin questionnaire, body mass index and AHI increased with increasing grade of DISE. DISE grades 1–5 were observed in 0% (0), 5% (2), 37.5% (15), 27.5% (11) and 30% (12) patients respectively. Muller’s manoeuvre showed lateral wall collapse in 40% (16) patients and concentric collapse in 40% (16) patients. Airway patency improved with jaw thrust in 60% (24) patients. Significant association of DISE was found with MPC (p = 0.028), TMD (p = 0.003), MHD (p = 0.008) and NC/TMD ratio (p = 0.002), effect of Muller’s manoeuvre (p =0.002), and effect of jaw thrust (p = 0.000). Conclusions Bedside screening tests MPC, TMD, NC/TMD ratio and MHD correlate significantly with level of obstruction during DISE.

Abstract
BACKGROUND The first edition of the European position paper (EPP) on drug-induced sleep endoscopy (DISE) was published in 2014 with the aim to standardise the procedure, to provide an in-depth insight into the main aspects of this technique and to have a basis for future research. Since 2014, new studies have been published concerning new sedative agents or new insights into the pattern/levels of the obstruction depending on the depth of sedation. Therefore, an enlarged group of European experts in the field of sleep breathing disorders (SBD), including the most of the first DISE EPP main authors, has decided to publish an update of the European position paper on DISE, in order to include new evidence and to find a common language useful for reporting the findings of this endoscopic evaluation in adult population affected by SBD. METHODS The authors have evaluated all the available evidence reported in the literature and have compared experience among various departments in leading European centres in order to provide an update regarding the standardisation of the DISE procedure and an in-depth insight into the main aspects of this technique. RESULTS After the first European Position Consensus Meeting on DISE and its update, consensus was confirmed for indications, required preliminary examinations, where to perform DISE, technical equipment required, staffing, local anaesthesia, nasal decongestion, other medications, patient positioning, basics and special diagnostic manoeuvres, drugs and observation windows. So far, no consensus could be reached on a scoring and classification system. However, regarding this aim, the idea of an essential classification, such as VOTE with the possibility of its graded implementation of information and descriptions, seems to be the best way to reach a universal consensus on DISE classification at this stage. A common DISE language is mandatory, and attempts to come to a generally accepted system should be pursued.

Abstract
OBJECTIVES/HYPOTHESIS To evaluate the correlation of aging and upper airway collapse characteristics observed by drug-induced sleep endoscopy (DISE), and report the observed differences on obstructive sleep apnea (OSA) subjects, older and younger than 60 years. STUDY DESIGN Case series. METHODS This study analyzed the data of 200 OSA patients who underwent DISE between January 1, 2013 and June 30, 2017. The variables sex, body mass index (BMI), Epworth Sleepiness Scale score, tonsil size, modified Mallampati (MM) classification, apnea-hypopnea index (AHI), oxygen desaturation index (ODI), lowest oxygen saturation, and VOTE (velum, oropharynx, tongue base, epiglottis) classification were compared between two groups: <60 and ≥60 years old. RESULTS Older age had significant correlation with higher AHI, ODI, lower O2 nadir, multisite obstruction, combined upper (palatopharyngeal) + lower (hypopharyngeal) level obstructions, and complete anterior-posterior (AP) velum collapse pattern. Lateral oropharyngeal wall collapse was significantly lower in the older group. Findings remained statistically significant when adjusted for sex, BMI, tonsil size, and MM. CONCLUSIONS Aging was an independent factor that directly correlated with increased AHI and hypoxemia, multisites, combined levels of obstruction, and complete AP velum collapse pattern. Being older than 60 years had higher of complete AP velum collapse and lower incidence of lateral oropharyngeal wall collapse, regardless of OSA severity and tonsil size.

Abstract
STUDY OBJECTIVES Oral appliance therapy (OAT) can be an effective treatment option for patients with obstructive sleep apnea unable to tolerate continuous positive airway pressure. We hypothesize that drug-induced sleep endoscopy (DISE) can be useful in identifying patients who will benefit from OAT. METHODS A retrospective review of all patients who underwent DISE (DISE group) between January 2014 and June 2016 was carried out. We included patients if they received OAT based on recommendations made by DISE findings. A control group was designed by selecting a sample of patients undergoing polysomnography (PSG) with an oral appliance in place who had not undergone prior DISE (no DISE group). The two cohorts were compared to evaluate the hypothesis. RESULTS A total of 20 patients fit inclusion criteria for the DISE group and 20 patients for the no DISE group. There was no difference between the DISE and no DISE cohorts with respect to mean age, sex, pre-OAT body mass index, post-OAT body mass index, or pre-OAT PSG characteristics including: apneahypopnea index (AHI), oxygen desaturation nadir, or Epworth Sleepiness Scale score. There was a significantly lower treatment AHI (P = .04) and increased number of patients reaching an AHI less than 5 events/h with OAT therapy (P = .04) in the DISE group. CONCLUSIONS Patients showing increased airway dimensions at the level of the velum and/or oropharynx with a jaw thrust may benefit the most from OAT. The use of DISE to identify this subset of patients is helpful in optimizing outcomes with OAT.

Abstract
The aim of this study was to establish a standardized protocol for drug-induced sleep endoscopy (DISE) to differentiate obstruction patterns in obstructive sleep apnea (OSA). Target-controlled infusion (TCI) of the sedative propofol was combined with real-time monitoring of the depth of sedation using bispectral analysis. In an observational study 57 patients (mean age 44.8 years, ± SD 10.5; mean apnea hypopnea Index (AHI) 30.8/hr, ± SD 21.6, mean BMI 28.2 kg/m2, ± SD 5.3) underwent cardiorespiratory polysomnography followed by DISE with TCI and bispectral analysis. Sleep was induced solely by the intravenous infusion of propofol with a TCI-pump, with an initial target plasma level of 2.0 µg/ml. Under continuous monitoring of the patient's respiration, state of consciousness and value of the bispectral analysis, the target plasma propofol level was raised in steps of 0.2 µg/ml/2 min until the desired depth of sedation was reached. The mean value of the bispectral analysis at the target depth of sedation was determined and the obstruction patterns during DISE-TCI-bispectral analysis then classified according to the VOTE-system. Subsequently the results were analyzed according to polysomnographic and anthropometric data. The occurrence of multilevel obstruction sites across all degrees of severity of OSA clarifies the need for sleep endoscopy prior to upper airway surgery. The advantage of this technique is the reproducibility of the protocol even for heterogeneous groups of patients. In addition, the gradual controlled and standardized increase of the plasma level of propofol with real-time control of the bispectral index leads to a precisely controllable depth of sedation. The DISE-TCI-bispectral analysis procedure is a step towards a required reproducible protocol of sleep endoscopy - capable of standardization. However it is not yet known whether these observed obstruction patterns also correspond to findings in natural sleep.

Abstract
OBJECTIVE To compare VOTE classification findings (velum, oropharyngeal-lateral walls, tongue base, and epiglottis) for drug-induced sleep endoscopy (DISE) among patients with obstructive sleep apnea (OSA) using 2 sedation protocols. STUDY DESIGN Case series with chart review. SETTING Single tertiary institution. SUBJECTS Patients with OSA who underwent DISE. METHODS A total of 216 patients underwent DISE between November 23, 2011, and May 1, 2015. DISE findings based on VOTE classification were compared between patients receiving the propofol- and dexmedetomidine-based sedation protocols. RESULTS Patients with OSA (N = 216; age, 44.3 ± 11.7 years; body mass index, 27.9 ± 4.8 kg/m(2)) underwent DISE with intravenous administration of propofol (n = 52) or dexmedetomidine (n = 164). There were no statistically significant differences between the 2 groups in baseline apnea-hypopnea index, oxygen desaturation index, Mallampati score, tonsil size, Epworth Sleepiness Scale score, peripheral oxygen saturation nadir, age, sex, or body mass index. Patients in the propofol group had a significantly increased likelihood of demonstrating complete tongue base obstruction (75%, 39 of 52) versus partial or no obstruction (25%, 13 of 52) in the anterior-posterior dimension, as compared with the dexmedetomidine group (complete obstruction: 42.7%, 70 of 164; partial or no obstruction: 57.3%, 94 of 164; odds ratio: 4.0; 95% confidence interval: 2.0-8.1; P = .0001). Obstruction of other airway subsites was not significantly different. CONCLUSION Use of propofol versus dexmedetomidine to induce sedation may have a significant effect on the pattern of upper airway obstruction observed during DISE. Randomized prospective studies are indicated to confirm these initial findings.

Abstract
OBJECTIVES/HYPOTHESIS The treatment for obstructive sleep apnea syndrome (OSAS) depends on correct localization of upper airway obstruction, exception made for continuous positive airway pressure (CPAP). Drug-induced sleep endoscopy (DISE) with propofol allows this evaluation, but the drug effects on sleep parameters are not yet well established. Our objective was to study by polysomnography (PSG) whether propofol would change sleep parameters by means of a prospective cross-sectional clinical study in a tertiary hospital. STUDY DESIGN Thirty non-obese subjects (6 controls and 24 OSAS patients) underwent two daytime PSGs, one with DISE and the other without DISE. METHODS During DISE exam, propofol was administered intravenously in continuous infusion using a target-controlled infusion pump. The parameters evaluated were: presence of snoring, apnea-hypopnea index (AHI), oxyhemoglobin saturation (SaO2), and sleep macroarchitecture. RESULTS Snoring was absent in all healthy subjects during DISE sleep with propofol, and present in all OSAS patients (100%). AHI and mean SaO2 showed no statistical difference between the two tests, with and without propofol. However, minimum SaO2 was significantly lower during propofol infusion (88.64 for without vs. 85.04 for with propofol; P < 0.01). Regarding sleep macroarchitecture, the tests with propofol significantly increased N3 sleep and totally extinguished REM sleep (P < 0.005). CONCLUSIONS The results demonstrate that propofol significantly changes sleep macroarchitecture. However, the main respiratory parameters, AHI and mean SaO2 , remained unaffected. Thus, in order to determine the sites of obstruction, propofol DISE used with target-controlled infusion proved to be an effective drug for endoscopic evaluation of patients with OSAS.
