Does a correlation exist between nasal airway volume and craniofacial morphology: A cone beam computed tomography...

Area of Science:

• Dentistry
• Radiology
• Anthropology

Background:

• Nasal airway volume is crucial for respiratory function.
• Craniofacial morphology influences overall facial structure and function.
• Understanding the relationship between nasal volume and facial dimensions is important in orthodontics and maxillofacial surgery.

Purpose of the Study:

• To investigate the correlation between nasal airway volume and various craniofacial morphology parameters.
• To determine if specific craniofacial dimensions influence nasal airway volume.

Main Methods:

• Utilized cone beam computed tomography (CBCT) scans from 34 healthy adults (18-28 years).
• Calculated nasal airway volume using Dolphin 3D software with a semi-automatic segmentation method.
• Grouped subjects based on sagittal skeletal relation, craniofacial width, facial index, and facial form.

Main Results:

• A statistically significant correlation was found between nasal airway volume and craniofacial width (P = 0.009).
• No significant correlation was observed between nasal volume and facial width/length ratio.

Conclusions:

• Nasal airway volume is significantly associated with craniofacial width.
• Facial proportions (width/length ratio) do not appear to significantly influence nasal airway volume in this cohort.
