[The influence of posture on nasal geometry]
1Third Clinical College, Bethune University of Medical Sciences, Changchun 130031.
Body posture significantly alters nasal cavity geometry. Changes in nasal volume and cross-sectional area occur with different positions, impacting airflow and requiring consideration in rhinological research.
Area of Science:
- Otolaryngology
- Anatomy
- Physiology
Context:
- Nasal cavity geometry influences airflow and respiratory function.
- Understanding anatomical changes is crucial for clinical and research applications.
- Previous research has not fully explored posture's impact on nasal geometry.
Purpose:
- To quantify the effects of different body and head postures on nasal cavity geometry.
- To measure changes in nasal volume and minimum cross-sectional area using acoustic rhinometry.
Summary:
- Acoustic rhinometry was used to measure nasal geometry in 35 healthy adults across various postures.
- Lateral recumbent positions with the wider nasal cavity down resulted in decreased volume and area.
- Reversing to the narrower side down position increased nasal volume and area.
Impact:
- Findings reveal a complex mucosal response to postural changes.
- Posture is a significant factor influencing nasal cavity dimensions.
- Recommendations for incorporating postural data in rhinological studies (environmental, clinical, pharmacological).

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
