[PMID: 37958018 PMCID: PMC10647320 DOI: 10.3390/healthcare11212874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 10/23/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023] Open
Abstract
Obstructive Sleep Apnea (OSA) is characterized by repetitive collapse of the upper airway during sleep. Drug-Induced Sleep endoscopy (DISE) is used to identify the collapse site. Among the possible sites of collapse, the epiglottis occurs more frequently than previously described. In this study, we reviewed DISE findings and classified different epiglottic collapse patterns. We found 104 patients (16.4%) with epiglottis collapse (primary 12.5% and secondary 3.9%). We described the following patterns of epiglottis collapse: Anterior-Posterior (AP) collapse with rigid component "trapdoor type" (48%); AP collapse with lax component "floppy type" (13.5%); Lateral- Lateral (LL) collapse with omega shape component "book type" (14.5%); and secondary due to lateral pharyngeal wall or tongue base collapse (24%). The identification of the epiglottic collapse pattern is crucial in decision-making when attempting to ameliorate OSA. These findings in OSA phenotyping could influence the type of treatment chosen.

Auris Nasus Larynx 2021; 49:235-239. [PMID: 34454780 DOI: 10.1016/j.anl.2021.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 06/29/2021] [Accepted: 08/11/2021] [Indexed: 11/28/2022]
Abstract
Objective The purpose of this study was to compare surgical outcomes for obstructive sleep apnea (OSA) when the procedure was based on the results of drug-induced sleep endoscopy (DISE) vs. the awake Müller's maneuver (MM). Methods Forty-seven patients with OSA who underwent sleep surgery were included. Patients were divided into 2 groups according to their preoperative upper airway evaluation method. Twenty-five patients received only MM for surgical decision making (MM group), and 22 patients received both MM and DISE (DISE group) for surgical decision making. Results The surgical success rate of the DISE group was higher than that of the MM group (59% vs. 36%), but the difference was not significant (p = 0.118). The differences between pre- and postoperative apnea-hypopnea index (AHI) values in both the MM and DISE group were highly significantly different (p < 0.001). Fifteen patients in the DISE group (68.2%) received multi-level surgery, while in the MM group only 7 patients (28%) received multi-level surgery. Patients with more severe OSA (AHI > 22 or lowest O2 saturation < 81%) had better surgical outcomes when their surgical procedures were based on the findings of DISE, rather than those of MM. Conclusion The results indicate that DISE provides no benefits with respect to surgical outcomes for patients with mild to moderate OSA; however, for patients with more severe OSA surgical procedures based on DISE result in better outcomes.

Abstract
Objective To systematically review the scoring systems used to report findings during drug-induced sleep endoscopy (DISE) for adults and children with obstructive sleep apnea. Data Sources PubMed, CINAHL, EBM Reviews, Embase, and Scopus databases. Review Methods This is a systematic review of all indexed years of publications referring to scoring of DISE for children and adults with obstructive sleep apnea. The type of DISE scoring system utilized was the primary outcome. PRISMA guidelines were followed to carry out this review; articles were independently reviewed by 2 investigators. All pediatric and adult studies that utilized ≥1 DISE grading systems were included. Results Of 492 identified abstracts, 44 articles (combined population, N = 5784) were ultimately included; 6 reported on children, 35 on adults, and 1 on children and adults. Twenty-one reporting methods were used in these studies, with the most common being the VOTE system (velum, oropharynx, tongue base, and epiglottis; 38.6%) and the Pringle and Croft classification (15.9%). The sites of obstruction most commonly included in a scoring system were the tongue base (62%), lateral pharynx/oropharynx (57%), palate (57%), epiglottis/supraglottis (38%), and hypopharynx (38%). Less commonly included sites were the larynx (29%), velum (23%), nose (23%), tongue (14%), adenoids (10%), and nasopharynx (10%). Conclusion There is no consensus regarding which scoring system should be utilized to report findings during DISE. The VOTE system and the Pringle and Croft classification were the most frequent scoring systems reported for patients undergoing DISE. Standardization of the reporting of DISE findings would improve comparability among studies.

Craniofacial and upper airway morphology in adult obstructive sleep apnea patients: A systematic review and meta-analysis of cephalometric studies. Sleep Med Rev 2016; 31:79-90. [PMID: 27039222 DOI: 10.1016/j.smrv.2016.01.007] [Citation(s) in RCA: 199] [Impact Index Per Article: 24.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2015] [Revised: 01/15/2016] [Accepted: 01/24/2016] [Indexed: 12/14/2022]
Abstract
Obstructive sleep apnea (OSA) is one of the common sleep breathing disorders in adults, characterised by frequent episodes of upper airway collapse during sleep. Craniofacial disharmony is an important risk factor for OSA. Overnight polysomnography (PSG) study is considered to be the most reliable confirmatory investigation for OSA diagnosis, whereas the precise localization of site of obstruction to the airflow cannot be detected. Identifying the cause of OSA in a particular ethnic population/individual subject helps to understand the etiological factors and effective management of OSA. The objective of the meta-analysis is to elucidate altered craniofacial anatomy on lateral cephalograms in adult subjects with established OSA. Significant weighted mean difference with insignificant heterogeneity was found for the following parameters: anterior lower facial height (ALFH: 2.48 mm), position of hyoid bone (Go-H: 5.45 mm, S-H: 6.89 mm, GoGn-H: 11.84°, GoGn-H: 7.22 mm, N-S-H: 2.14°), and pharyngeal airway space (PNS-Phw: -1.55 mm, pharyngeal space: -495.74 mm2 and oro-pharyngeal area: -151.15 mm2). Significant weighted mean difference with significant heterogeneity was found for the following parameters: cranial base (SN: -2.25 mm, S-N-Ba: -1.45°), position and length of mandible (SNB: -1.49° and Go-Me: -5.66 mm) respectively, maxillary length (ANS-PNS: -1.76 mm), tongue area (T: 366.51 mm2), soft palate area (UV: 125.02 mm2), and upper airway length (UAL: 5.39 mm). This meta-analysis supports the relationship between craniofacial disharmony and obstructive sleep apnea. There is a strong evidence for reduced pharyngeal airway space, inferiorly placed hyoid bone and increased anterior facial heights in adult OSA patients compared to control subjects. The cephalometric analysis provides insight into anatomical basis of the etiology of OSA that can influence making a choice of appropriate therapy.
