Muscles that Move the Head

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Summary

Low pull headgear (LHG) therapy did not significantly alter head position in growing males with Class II malocclusion. Postural variables remained stable over 11-12 months in both treated and untreated groups.

Area of Science:

Orthodontics
Craniofacial Growth
Cephalometric Analysis

Background:

Class II malocclusion is common in growing individuals.
Orthodontic interventions aim to correct skeletal and dental discrepancies.
Headgear is frequently used to modify maxillary growth and/or protraction.

Purpose of the Study:

To assess the effect of low pull headgear (LHG) on head posture.
To compare cephalometric changes in head position between LHG users and an untreated control group.

Main Methods:

Lateral cephalograms of 30 males (aged 11 ± 1.5 years) treated with LHG for Class II malocclusion were analyzed.
Cephalograms from 25 untreated males (aged 11 ± 1.6 years) served as controls.
Four postural variables (NSL/CVT, NSL/OPT, CVT/HOR, OPT/HOR) were measured pre- and post-treatment/observation.

Main Results:

No statistically significant changes in head position were observed within the LHG group (p > 0.05).
No statistically significant changes in head position were observed within the control group (p > 0.05).
There were no significant differences in head position changes between the LHG and control groups for any measured postural variable (p > 0.05).

Conclusions:

Low pull headgear therapy does not induce significant changes in head posture in growing males.
Head position remains relatively stable over an 11-12 month period, irrespective of LHG treatment.
Individual variability in postural changes exists, but treatment effects are not statistically significant.
