In an adult cohort, tongue strength did not differ among patients with mild, moderate, and severe OSA. However, in non-obese patients (BMI < 30 kg/m²), tongue strength was lower in those with severe OSA compared to those with mild OSA. Future studies on the impact of tongue strength may be best directed at non-obese patients with OSA.
Sattaratpaijit et al. (Sun,) studied this question.
