Background: Mask ventilation is an essential part of airway management. Head rotation increases the cross-sectional area of upper airway and improves upper airway patency. Methods: A prospective crossover study in 40 patients aged 18-69, ASA physical status I, II, III and who needed general anesthesia with tracheal intubation were selected, divided into two groups of 20 each, group I and Group II. When apnea was achieved after standard general anaesthesia, mask ventilation was performed using pressure-controlled ventilation, peak inspiratory pressure 15 cm of water, 10 breaths per minute, I:E ratio 1:2. Face mask held by two hands. Group I patients received mask ventilation with the head in a neutral position for one minute, after which the head was turned to the right for one minute and the head is returned to the neutral position for one minute. In group II patients, mask ventilation was performed from right lateral position to neutral position to right lateral position. In each position, airway pressure, compliance and expiratory tidal volume were measured. Results: There was no statistically significant difference between groups with respect to demographic data. The mean expiratory tidal volume was high in head rotation than neutral position (469.545±120.09 ml vs. 397.815±86.03 ml) p value <0.05. A statistically significant (p value=0.045) seen with respect to compliance which was slightly higher in head rotation (35.83) than neutral position (29.31). Conclusions: Head rotation to the lateral position increases the expiratory tidal volume and compliance significantly as compared to head in neutral position and improves mask ventilation after induction of anaesthesia.

“…The FHP is a protracted position in which the lower cervical region is exed and glides anteriorly, and the upper cervical complex is extended [8]. The FHP increases the load on the neck and fatigue of the neck extensors [9], affects craniofacial growth [10], interacts with temporomandibular joint disorder (TMD), changes the craniofacial morphology and hyoid bone position [11,12], and affects the morphology of the upper airway [13]. Therefore, head posture changes may be considered in the measurement of the craniofacial morphology and hyoid bone position.…”

Background Posture assessment is an important part of clinical physical examination. Head posture changes may be considered in the measurement of the craniofacial morphology and hyoid bone position. This study aimed to compare the craniofacial morphology and hyoid bone position in the neutral head posture (NHP) and forward head posture (FHP) in healthy individuals. Methods Forty healthy participants (16 male and 24 female individuals) were included in this study. Using lateral cephalograms, we assessed the craniofacial, craniocervical, and hyoid bone positions based on 27 distinct variables. For comparison between the two groups, the paired-samples t-test was used for normally distributed data. Pearson’s correlation analysis determined correlations between the craniofacial and hyoid bone positions and craniofacial variables in both postures. Results There were significant differences in the craniocervical angles between the NHP and FHP groups. For the hyoid bone position, all parameters except the linear distance between the hyoidale and cv3ia showed differences. Vertical variables of craniofacial morphology, such as the anterior and posterior facial heights, were influenced by head posture. Pearson's correlation coefficients showed that head posture had a significant correlation with craniofacial morphology, particularly for vertical variables. Conclusions This study found a relationship between the craniocervical and hyoid positions and craniofacial morphology. Different head postures can influence the hyoid position and craniofacial morphology. For studies involving these parameters and related conditions, maintaining cervical spine posture is crucial.
