The size of the patient’s neck, as measured by the neck circumference, has been studied in the past in evaluating patients with obstructive sleep apnea (OSA). To the best of our knowledge there has been no studies done to investigate if the neck circumference is related to the patient’s symptoms. The purpose of this study is to evaluate the association between the neck circumference, the Epworth sleepiness scale, and the Apnea-Hypopnea Index (AHI).
We reviewed the sleep studies of 73 patients referred to our sleep lab for suspected obstructive sleep apnea (OSA) and compared their demographic data, their AHI, their neck circumferences, and their Epworth sleepiness scales.
We found that there was a strong association between the neck circumference and the sleepiness scale (p value of 0.0003), and a weaker association between the neck circumference and the AHI (p value of 0.0010). The higher the neck circumference, the higher the Epworth sleepiness scale and the more likely these patients are to have sleepiness symptoms.
We conclude that patients with higher neck circumferences are more likely to be symptomatic than patients with lower neck circumferences regardless of the level of AHI. The size of the neck appears to predict the severity of sleepiness symptoms that these patients display as indicated by the Epworth sleepiness scale. Further studies are needed with larger numbers of patients to evaluate the usefulness of this observation.
The size of the Patient’s neck as indicated by the measurement of the neck circumference appears to predict the severity of symptoms in patients with obstructive sleep apnea.
