The anesthesiologist should consider all the risk factors and presenting symptoms of obstructive sleep apnea. When in doubt as to the presence of sleep apnea OSA, the patient should be treated as if it is present (and consider whether it is appropriate to delay surgery until the OSA has been diagnosed and treated). Anesthesiologist should provide appropriate postoperative monitoring and CPAP should be used in the recovery room and in the patients room. It can never be overemphasized that with meticulous preparation, careful maintenance of the airway during surgery, and postoperative vigilance, anesthesia can be delivered safely on obstructive sleep apnea patients. Lastly, the anesthesiologists also have an important role to help increase the recognition of the obstructive sleep apnea among their patients by through screening and to take the necessary steps, including informing hospital staff and family members of the precarious relationship between obstructive sleep apnea and anesthesia.

Introduction: Obstructive sleep apnea (OSA) is the most common breathing-related sleep disorder. OSA is mainly characterized by a set of symptoms resulting from apnea events that have negative outcomes on health, such as excessive daytime sleepiness, cardiovascular impairment, and increased morbidity and mortality. It is important to develop simple, reliable, cost-effective methods to predict obstructive sleep apnea. Neck circumference - height ratio has limited studies in its relation to obstructive sleep apnea compared to neck circumference. Method: This is a retrospective cross-sectional study using chart review of all patients who had been diagnosed with obstructive sleep apnea by polysomnogram at the Lung Center of the Philippines from January 2019 to December 2019. Demographic characteristics like age, gender, weight, height, neck circumference, BMI, neck circumference - height ratio [NHR], and apnea-hypopnea index were determined. Accuracy of the neck circumference - height radio cutoff had been determined in predicting obstructive sleep apnea and its severity by comparing neck - circumference - height ratio cut-off with a polysomnogram. Results: Among the 384 charts collected and reviewed, this study had a total of 194 participants were included. Most participants were male (72.68%) and the age range was between 35 to 60 years old. There were 12 (6%) participants in the Mild OSA group, 19 (10%) in the Moderate OSA group, and 163 (84%) were categorized as Severe. Median Neck Circumference -Height Ratio was 0.23 to 0.26. A cutoff of > 0.23 NHR was used to predict Mild OSA showed PPV of 46.15% (24.47 to 65.98), NPV was 66.67% (50.78 to 79.49), AUC of 0.5307 (0.30 to 0.76), and accuracy of 58.06% (39.08 to 75.45). A cutoff of > 0.23 NH was used to predict Moderate OSA showed positive predictive value (PPV) was 15.94% (10.91 to 22.7), NPV of 93.6% (89.52 to 96.16), AUC of 0.6421 (0.52 to 0.77), and accuracy of 65.98% (58.85 to 72.61). A cutoff of > 0.23 HR was used to predict Severe OSA showed PPV of 15.94% (10.91 to 22.7), NPV of 93.6% (89.52 to 96.16), AUC of 0.6421 (0.52 to 0.77), and accuracy of 65.98% (58.85 to 72.61). Conclusion The HR cut-off demonstrated a moderate positive correlation with OSA, and NH increases as the apnea-hypopnea index are increased. NH cut-off of 0.23 is sufficient to predict severe OSA but has poor diagnostic accuracy for mild and moderate OSA. Moreover, the HR cut-off may also be an integral tool to predict severe OSA.

To evaluate the cephalometric and dental characteristics of obstructive sleep apnea (OSA) patients, 23 OSA patients and 15 control, non-OSA, patients who visited the Sleep Disorder Clinic Center, Keimyung University were investigated. Patients who suffered from apnea-hypopnea episodes over 10 times per hour were diagnosed as having OSA after polysomnograph testing. Impressions were taken with alginate. Cephalometric radiographs were taken at maximum intercuspation. The dental cast measurements, including transpalatal width, intercanine width, intermolar width and palatal depth did not differ between the control and OAS groups and did not have a positive correlation with the apnea-hypopnea index (AHI). Upper airway width was statistically narrower than the control group. Upper airway width had a low negative correlation with AHI, but, lower airway width had a low positive correlation, and, the higher the AHI score, the longer the mandibular border to hyoid distance.
