Some breathing indexes during sleep, including the apnea-hypopnea index, oxygen desaturation index, and oxygen saturation during sleep, can be recorded by overnight polysomnography. We aimed to investigate the association of various breathing indexes during sleep with the Epworth Sleepiness Scale (ESS) score in adults. We retrospectively collected...

Background
Pre-operative imaging tools play a crucial role in the anatomic assessment of the upper airway and adjacent structures in obstructive sleep apnea patients. The current study was aimed at comparing and correlating the results of videofluoroscopy in evaluating upper airway obstruction in surgically fit obstructive sleep apnea “OSA” patient...
Objective Obstructive sleep apnea syndrome (OSAS) is characterized by episodic cessations of breathing due to upper airway obstruction during sleep, which may cause disturbances in dietary patterns resulting from appetite-related hormonal changes. The aim of the present study was to investigate the relationship between OSAS and nutritional and diet...
Background
Obstructive sleep apnea (OSA) is a prevalent disease associated with increased risk of cardiovascular mortality. However, the exact causal relationship is not clear. One of the proposed mechanisms is dyslipidemia.
Aim
To study the effect of continuous positive airway pressure (CPAP) on dyslipidemia in patients with OSA.
Patients and me...
Purpose
The objective was to determine if alteration in airflow induced by negative pressure (NP) applied to participants’ upper airways during wakefulness, is related to obstructive sleep apnea (OSA) severity as determined by the apnea–hypopnea index (AHI).
Methods
Adults 18 years of age or greater were recruited. All participants underwent overn...
Background
Obstructive sleep apnea (OSA) is a heterogeneous sleep disorder often comorbid with metabolic diseases, and type 2 diabetes (T2DM) is one of them. Although apnea hypopnea index (AHI) is currently the diagnostic criteria for OSA severity, a controversial relationship between AHI and T2DM has been found. On the other hand, the duration of...

Objective: We aimed to determine the correlation of Modified Mallampati scoring and Brodsky tonsillar grading as indicative factor for sleep disordered breathing by using an Epworth sleepiness scale in patients with hypertrophic tonsils. Methodology: Data for this prospective cross-sectional analytical study was collected at an ENT Department of PNS Shifa Hospital, Karachi between January to July 2021. Non-probability consecutive sampling technique was used. After taking informed consent, a subject evaluation proforma was filled which involved detailed personal history of the selected subjects with hypertrophic tonsils and sleep disordered breathing. Epworth sleepiness scale was assessed, Physical examination of subjects involved grading of tonsils and examination of the tongue was done. Data was entered and analyzed on SPSS 23.0 software. Results: The present study enrolled (n=54) adult subjects with mean age calculated to be 25.72 ± 7.9 SD. Pre-operative Epworth scores were significantly lower in subjects with Brodsky grade I and II as compared to higher grades which is in accordance with increasing severity of obstruction as tonsil grading advanced. Furthermore, statistically significant association was seen between Epworth scoring and Mallampati grading. Conclusion: The results of the current study generated significant recommendations for the evaluation of the anatomy of pharynx, use of Epworth questionnaire, Mallampati and Brodsky classification might be a rapid, non-invasive screening tool for advance identification and timely intervention for subjects at risk of sleep disordered breathing.

Introduction
A common practice in clinical settings is the use of the Epworth Sleepiness Scale (ESS) and apnea-hypopnea index (AHI) to demonstrate the severity of obstructive sleep apnea (OSA). However, several instances were noted where there were discrepancies in the reported severity between Epworth scores and AHI in our patient sample, prompting an investigation into whether OSA severity as demonstrated by AHI or predicted by ESS quantification of sleepiness is primarily responsible for inconsistencies.
Methods
Discrepancies were examined between Epworth scores and AHI by categorizing patients into two categories of inconsistency: individuals with either ESS < 10 and AHI ≥ 15 events/h or ESS ≥ 10 and AHI < 15 events/h. The potential influence of sex on these categories was addressed by assessing whether a significant difference was present between mean Epworth scores and AHI values for men and women in the sample. We investigated BMI both by itself as its own respective variable and with respect to the sex of the individuals, along with a consideration into the role of anxiety. Furthermore, we tested anxiety with respect to sex.
Results
In the first category of inconsistency the average ESS of 5.27 ± 0.33 suggests a normal level of daytime sleepiness. However, this contrasts with the average AHI of 32.26 ± 1.82 events/h which is indicative of severe OSA. In the second category the average ESS of 14.29 ± 0.47 suggests severe daytime sleepiness, contradicting the average AHI of 9.16 ± 0.44 events/h which only indicates mild OSA. Sex, BMI (both as a variable by itself and with respect to sex), and anxiety (both as a variable by itself and with respect to sex) contributed to observed inconsistencies.
Conclusion
The findings of our study substantiate our hypothesis that Epworth scores should be de-emphasized in the assessment of OSA and a greater importance should be placed on measures like AHI. While Epworth scores offer insights into patients’ daytime sleepiness levels and the perceived severity of their OSA, the inconsistencies highlighted in our results when compared to AHI-based OSA severity underscore their potential inaccuracy. Caution is advised when utilizing Epworth scores for evaluating OSA severity in clinical settings.
