Insights

Asthma children exhibit altered craniocervical posture and hyoid bone positioning compared to healthy children. Increased asthma severity correlates with greater upper cervical spine extension.

Area of Science:

  • Orthodontics and Dentofacial Orthopedics
  • Pediatric Pulmonology
  • Radiology

Background:

  • Mouth breathing is common in children with asthma.
  • Craniocervical posture and hyoid bone position may be affected in these children.

Purpose of the Study:

  • To compare craniocervical posture and hyoid bone positioning in children with asthma who are mouth breathers versus non-asthma controls.
  • To investigate the relationship between asthma severity and cervical spine posture.

Main Methods:

  • Radiographic analysis of 56 children (28 with asthma, 28 controls) using lateral teleradiography and cervical spine radiography.
  • Measurement of variables including Craniovertebral Angle (CVA) and hyoid triangle.
  • Statistical analysis using independent t-test, chi-square test, and ICC for reliability.

Main Results:

  • Asthma children had a significantly smaller Craniovertebral Angle (CVA) compared to controls.
  • A higher frequency of absent or inverted hyoid triangle was observed in children with asthma.
  • Moderate asthma severity was associated with greater superior cervical spine inclination than mild asthma.

Conclusions:

  • Children with asthma display altered head extension and hyoid bone position compared to non-asthma children.
  • The severity of asthma is positively correlated with the degree of upper cervical spine extension.

The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
