Abstract

Abstract: Introduction: Estimating the severity of obstructive sleep apnea using a clinical score of the oropharyngeal airway which is more accurate than the Modified Mallampati Classification. Methods: Retrospective review of consecutive adult patients presenting to a community-based sleep clinic for evaluation over a period of one year. Each patient underwent a diagnostic polysomnogram in an AASM accredited sleep center. Patient demographic data including age, neck size, BMI, gender, Epworth sleepiness scale along with the Modified Mallampati Class (MMC) was recorded at the initial visit and compared to the apnea-hypopnea index (AHI) reported on the polysomnogram. Initially a standard MMC was noted on clinical exam. Immediately thereafter, the patient was asked to take a single breath in through the nasal route only. The change in MMC (if any) was recorded as a corrected score. This was named the Gupta Score (GS). Results: A total of 198 patients (108 male) undergoing diagnostic polysomnogram were included. Age 19-86, BMI 18-72.8, Neck size 12.5"-22", Epworth 0-23, and AHI 0-122 events/hour. 97 patients were diagnosed with obstructive sleep apnea (OSA). Data demonstrated that patients fell into the following MMC classifications. MMC I=19 patients with mean AHI=25.98, MMC II=65 patients with mean AHI=36.43, MMC III=17 patients with mean AHI=46 and MMC IV=2 patients with mean AHI=41.2. Data from the Gupta Score were as follows. GS I=1 patient with mean AHI=5.8, GS II= 10 patients with mean AHI=19.39, GS III=65 patients with mean AHI=36.45, GS IV= 27 patients with mean AHI=43.23. Conclusion: Modified Mallampati classification is not a useful tool in clinical assessment to predict severity of obstructive sleep apnea. The Gupta Score increases the probability of diagnosing a patient with obstructive sleep apnea and its severity as indicated by this study. Incorporating the Gupta score in the routine clinical exam across various medical specialties may result in a greater number of patients being diagnosed and treated for obstructive sleep apnea.
