Pharyngeal Airway and Craniocervical Angle among Different Skeletal Patterns

Area of Science:

• Orthodontics and Dental Anatomy
• Craniofacial Morphology
• Airway Physiology

Background:

• Pharyngeal airway dimensions are critical for respiratory function.
• Skeletal patterns and craniocervical angulation influence craniofacial development and airway space.
• Understanding these relationships aids in diagnosing and managing conditions affecting the pharyngeal airway.

Purpose of the Study:

• To investigate pharyngeal airway dimensions in relation to skeletal patterns.
• To explore correlations between craniocervical angle and pharyngeal airway size.
• To determine if skeletal patterns influence specific pharyngeal airway measurements.

Main Methods:

• Cephalometric radiographs of 300 patients (≥15 years) were analyzed.
• Patients were classified into three skeletal pattern groups.
• Measurements included nasopharyngeal airway (NP), soft palate to pharyngeal wall distance (PS), and others; craniocervical and ANB angles were also assessed.

Main Results:

• Class III patterns showed significantly greater PS, TS, and MP lengths than Class I and II.
• The ANB angle correlated moderately with palatal angle and negatively with TS and MP.
• Class II had a significantly greater C4C2-SN angle and longer palatal length (PL) than Class III.

Conclusions:

• Class III skeletal patterns are associated with larger pharyngeal airway dimensions (PS, TS, MP).
• Pharyngeal airway dimensions demonstrate correlations with specific skeletal and craniocervical parameters.
• Findings reject the null hypothesis, indicating significant differences in airway dimensions among skeletal patterns.
