Can chin-nape circumference and the ratio of neck circumference to chin-nape circumference predict difficult mask ventilation or difficult intubation in obese patients?

ABSTRACT: We aimed to evaluate the success of the ratio of chin-nape circumference (CNC) and neck circumference (NC) to CNC in predicting difficult mask ventilation (DMV) or difficult intubation (DI). Eighty-seven obese patients (body mass index ≥ 30) were evaluated between September 15, 2019 and September 15, 2020. Mallampati score, mouth opening, upper lip bite test, distance between incisors, thyromental distance (TMD), sternomental distance (SMD), and thyromental height were recorded. NC and CNC were measured in a neutral position. The ratio of NC to TMD and the ratio of NC to CNC were calculated. Mask ventilation was graded according to the method described by Han et al (Grade 3 or 4 equals DMV). DI assessment was performed using the intubation difficulty scale (IDS, IDS < 5 equals easy intubat
