Summary
Haller
Area of Science:
- Anatomy
- Radiology
- Otolaryngology
Background:
- Haller's cells are ethmoidal pneumatizations affecting the maxillary sinus and orbit floor.
- Their clinical significance necessitates understanding their prevalence and characteristics.
Purpose of the Study:
- To determine the prevalence and characteristics of Haller's cells using panoramic radiography.
- To analyze the anatomical variations of Haller's cells in a large adult cohort.
Main Methods:
- Panoramic radiographs of 600 healthy adults (18-60 years) were analyzed.
- Statistical analysis included frequencies, percentages, and chi-square tests.
- Presence, laterality, shape, and type of Haller's cells were recorded.
Main Results:
- Haller's cells were identified in 16% of the study population (96 out of 600 patients).
- Unilateral occurrence was more frequent (77.1%) than bilateral (22.9%).
- The majority of identified cells were round/ovoid, with a statistically significant association between unilateral, unilocular Haller's cells.
Conclusions:
- Panoramic radiography is a viable tool for identifying Haller's cells.
- Understanding Haller's cell characteristics aids in diagnosing orofacial pain and preventing complications in endonasal surgery.
