This study reviews nasal cavity and paranasal sinus physiology, air flow computer modeling, and gas composition. It explores factors affecting nitric oxide (NO) levels in these crucial respiratory areas.
Area of Science:
- Respiratory physiology
- Biomedical engineering
- Computational fluid dynamics
Context:
- The nasal cavity and paranasal sinuses are vital for respiration and olfaction.
- Understanding airflow dynamics is key to respiratory health.
- Nitric oxide (NO) plays a role in sinonasal physiology.
Purpose:
- To consolidate current data on nasal cavity and paranasal sinus physiology.
- To present findings from computer modeling of airflow in these sinuses.
- To investigate the gas composition and nitric oxide (NO) concentration factors within the paranasal sinuses.
Summary:
- This paper synthesitsizes available physiological data for the nasal cavity and paranasal sinuses.
- It details results from national and international computer modeling studies on sinonasal airflow.
- The study examines gas composition and factors influencing nitric oxide (NO) levels in the nasal cavity and paranasal sinuses.
Impact:
- Provides a comprehensive overview for researchers and clinicians in rhinology.
- Highlights the importance of computational modeling in understanding sinonasal function.
- Offers insights into the role of nitric oxide (NO) in sinonasal health and disease.

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...
