The anatomic relevance of the Haller cell in sinusitis

Abstract:
In current theories of sinusitis, obstruction at the ostiomeatal complex leads to localized inflammation and infection. Haller cells, an extension of ethmoid pneumatization along the maxillary antrum roof, have also been suggested as a causative factor in sinusitis because of their ability to cause narrowing of the infundibulum. Coronal CT scans were reviewed in 154 patients to evaluate the role of Haller cells in sinusitis. Haller cells were present in 34% of patients. The cells were graded as small, medium, or large, and correlated with radiologic evidence of sinusitis (e.g., mucosal thickening or opacification). A statistically significant increase in maxillary sinus mucosal disease was noted in patients with medium or large Haller cells (45.8%) versus those with small cells (28.9%, p < 0.05). Thus obstructive medium and large Haller cells may be an etiologic factor in sinusitis.
Insights
Haller cells, an anatomical variation, are linked to sinusitis. Medium or large Haller cells significantly increase the risk of maxillary sinus mucosal disease, suggesting they are an important factor in sinusitis development.
Area of Science:
- Otolaryngology
- Radiology
- Anatomy
Background:
- Sinusitis theories often cite ostiomeatal complex obstruction.
- Haller cells, ethmoid air cells extending into the maxillary sinus, may narrow the infundibulum, contributing to sinusitis.
Purpose of the Study:
- To evaluate the association between Haller cells and sinusitis.
- To determine if Haller cell size correlates with sinusitis severity.
Main Methods:
- Coronal CT scans of 154 patients were reviewed.
- Haller cells were identified and graded (small, medium, large).
- Correlation between Haller cell size and radiologic sinusitis evidence (mucosal thickening, opacification) was analyzed.
Main Results:
- Haller cells were present in 34% of patients.
- Medium or large Haller cells showed a statistically significant increase in maxillary sinus mucosal disease (45.8%) compared to small Haller cells (28.9%).
Conclusions:
- Obstructive medium and large Haller cells are a potential etiologic factor in sinusitis.
- Haller cell size is a relevant consideration in the pathogenesis of sinusitis.

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...
