Class II skeletal malocclusion is comorbid with an elongated head posture. Balancing the head will involve the skull, spine, mandible, hyoid bone, respiratory tract, muscles, and tongue. The hyoid bone functions to maintain the balance of the head posture. To see the relationship of comorbid skeletal class II malocclusion with head posture, the relationship of the head posture of skeletal class II malocclusion with the width of the respiratory tract, and the relationship of the head posture of skeletal class II malocclusion with the hyoid bone position. Observational analytical study with a cross-sectional design using a sample of 60 skeletal class II malocclusion cephalograms divided into three subgroups. Skeletal class II malocclusion group with prognathic maxillary and normal mandible, normal maxillary and retrognathic mandible group, prognathic maxillary and retrognathic mandibular group. The cephalogram was traced and then scanned and measurements were taken using the CorelDRAW application. The chi-square test showed no significant relationship between the skeletal class II malocclusion and the head posture (P> 0.05). There is no significant relationship between the head posture in the skeletal class II malocclusion and the respiratory tract (P> 0.05). There is no meaningful relationship exists between the head posture in the skeletal class II malocclusion with vertical position and angular hyoid bone (P> 0.05). There is a significant relationship in the posture head of skeletal class II malocclusion subgroup prognathic maxillary and retrognathic mandibular with the anteroposterior position of the hyoid bone. The hyoid bone position is more posterior in the skeletal class II malocclusion subgroup prognathic maxillary and retrognathic mandibular. [ABSTRACT FROM AUTHOR]
