<jats:title>Summary</jats:title><jats:p>We conducted a clinical cross‐sectional study to examine the relationship between jaw‐opening force and the cross‐sectional area of the suprahyoid muscles and whole skeletal muscle mass. Subjects were healthy 39 males and 51 females without dysphagia and sarcopenia, aged 65 years and older. Jaw‐opening force was measured three times using a jaw‐opening sthenometer; the maximum of these three was taken as the measurement value. The cross‐sectional area of the geniohyoid and anterior belly of the digastric muscles were evaluated using ultrasonography. The skeletal muscle mass index, gait speed and grip strength were evaluated according to the diagnostic criteria of the Asian Working Group for Sarcopenia. For each sex, a multiple regression analysis determined the factors that affect jaw‐opening force. Jaw‐opening force was associated with the cross‐sectional area of the geniohyoid muscle in males (regression coefficient [β] = 0.441, 95% confidence interval [<jats:styled-content style="fixed-case">CI</jats:styled-content>] = 14.28‐56.09) and females (β = 0.28, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content> = 3.10‐54.57). Furthermore, in females only, jaw‐opening force was associated with the skeletal muscle mass index (β = 0.40, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content> = 3.67‐17.81). In contrast, jaw‐opening force was not associated with the cross‐sectional area of the anterior belly of the digastric muscle in either sex. In healthy elderly males and females, jaw‐opening force was positively associated with the cross‐sectional area of the geniohyoid muscle. However, the jaw‐opening force was positively associated with the skeletal muscle mass index only in females.</jats:p>
