The nasal valve (NV) region, critical for airflow resistance, has distinct anterior and posterior segments. This study clarifies terminology for these nasal structures.
Area of Science:
- Anatomy
- Physiology
- Rhinology
Background:
- The anterior nasal cavity, specifically the nasal valve (NV) region, significantly impacts nasal airflow resistance.
- Existing literature uses varied terminology for anatomical structures within the NV region.
Purpose of the Study:
- To investigate the functional anatomy of the nasal valve (NV).
- To establish clear definitions for the anatomical structures of the anterior nasal cavity, focusing on the NV region.
Main Methods:
- Literature review to identify and compare terminologies for nasal valve anatomy.
- Anatomical analysis of the anterior nasal cavity structures.
Main Results:
- The nasal valve (NV) region comprises distinct anterior and posterior segments.
- The anterior segment is identified as the 'internum ostium'.
- The posterior segment is identified as the 'isthmus nasi'.
Conclusions:
- The nasal valve (NV) region's anterior part is the 'internum ostium'.
- The nasal valve (NV) region's posterior part is the 'isthmus nasi'.

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...
