The total number of ethmoid cells (EC) is significantly higher in patients with chronic rhinosinusitis (CRS) compared to healthy individuals. This finding suggests EC count may play a role in CRS development.
Area of Science:
- Otolaryngology
- Medical Imaging
- Anatomy
Background:
- Chronic rhinosinusitis (CRS) is a common condition with complex pathophysiology.
- The role of anatomical variations, such as ethmoid cell (EC) count, in CRS development requires further investigation.
Purpose of the Study:
- To investigate the association between the total number of ethmoid cells (EC) and the presence of chronic rhinosinusitis (CRS).
- To compare EC counts in patients with CRS, odontogenic CRS, and healthy controls.
Main Methods:
- Retrospective case-control study analyzing 50 CRS patients, 14 odontogenic CRS patients, and 50 healthy controls.
- Computed tomography (CT) scans were used to determine the bilateral total EC count in each subject.
- Statistical analysis compared EC counts between the groups.
Main Results:
- A significantly higher bilateral total EC count was observed in CRS patients compared to both healthy controls and odontogenic CRS patients (P < .01).
- No significant difference in EC count was found between healthy controls and odontogenic CRS patients.
Conclusions:
- The number of ethmoid cells (EC) is significantly elevated in patients with chronic rhinosinusitis (CRS).
- Increased EC count may be a contributing factor to the pathogenesis of CRS.

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...

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
