“…A pre-surgical patient evaluation includes a physical examination and a flexible fiberoptic nasopharyngoscopy to evaluate the upper airway to identify potential sites of collapse. Several other diagnostic modalities have showed some value to supplement a physical examination, including lateral cephalogram, 3-dimensional cone beam computed tomographic scan, sleep endoscopy, or cine-magnetic resonance imaging (MRI) [11][12][13]. The last 2 have been shown some promise because they evaluate static and dynamic aspects of the upper airway while asleep or in a sleep-like state.…”

Surgical Therapy of Obstructive Sleep Apnea: A Review

Obstructive sleep apnea (OSA) is a disease characterized by intermittent and repetitive narrowing of the airway during sleep. Surgical therapies for the treatment of OSA aim to improve airway patency by addressing selected site(s) of obstruction. Because several areas may each be responsible for the narrowing, different surgical modalities have also been developed. In this review, we give an overview of surgery for each of potential obstruction site(s). As a consequence of the multi-factorial and heterogeneous etiology of OSA, surgical therapies need to be selected and performed specifically for each patient, as there is no perfect surgery that will fit all patients. As with any other treatment modalities for OSA, surgical therapies have variable efficacy, but are a very important tool on OSA management in selected patients and have been shown effectiveness in decreasing the morbidity and mortality associated with the disease.

The Value of Oxygen Desaturation Index for Diagnosing Obstructive Sleep Apnea: A Systematic Review

et al. 2020

Objectives Intermittent hypoxemia is a risk factor for developing complications in obstructive sleep apnea (OSA) patients. The objective of this systematic review was to identify articles evaluating the accuracy of the oxygen desaturation index (ODI) as compared with the apnea–hypopnea index (AHI) and then provide possible values to use as a cutoff for diagnosing adult OSA. Study Design Systematic Review of Literature. Methods PubMed, the Cochrane Library, and SCOPUS databases were searched through November 2019. Results Eight studies (1,924 patients) met criteria (age range: 28–70.9 years, body mass index range: 21.9–37 kg/m2, and AHI range: 0.5–62 events/hour). Five studies compared ODI and AHI simultaneously, and three had a week to months between assessments. Sensitivities ranged from 32% to 98.5%, whereas specificities ranged from 47.7% to 98%. Significant heterogeneity was present; however, for studies reporting data for a 4% ODI ≥ 15 events/hour, the specificity for diagnosing OSA ranged from 75% to 98%, and only one study reported the positive predictive value, which was 97%. Direct ODI and AHI comparisons were not made because of different hypopnea scoring, different oxygen desaturation categories, and different criteria for grading OSA severity. Conclusion Significant heterogeneity exists in studies comparing ODI and AHI. Based on currently published studies, consideration should be given for diagnosing adult OSA with a 4% ODI of ≥ 15 events/hour and for recommending further evaluation for diagnosing OSA with a 4% ODI ≥ 10 events/hour. Screening with oximetry may be indicated for the detection of OSA in select patients. Further study is needed before a definitive recommendation can be made. Laryngoscope, 131:440–447, 2021
