Summary
The prevalence of Haller's cells (infraorbital ethmoid cells) on panoramic radiographs is 10%. Understanding these anatomical variations is crucial for surgeons performing endonasal procedures to prevent complications.
Area of Science:
- Radiology
- Anatomy
- Oral and Maxillofacial Surgery
Background:
- Haller's cells, also known as infraorbital ethmoid cells, are ethmoidal pneumatizations affecting the maxillary sinus floor and orbit.
- These anatomical variations appear as distinct radiolucencies on panoramic radiographs.
Purpose of the Study:
- To determine the prevalence of Haller's cells.
- To analyze the characteristics of Haller's cells observed on panoramic radiographs.
Main Methods:
- A cross-sectional study involving 300 individuals aged 8-80 years.
- Panoramic radiographs were analyzed by two radiologists for the presence of Haller's cells.
- Statistical analysis included Chi-square tests with significance set at p<0.05.
Main Results:
- Haller's cells were identified in 10% (30/300) of individuals.
- The prevalence was slightly higher in males (18) than females (12).
- Most Haller's cells were oval or round, with unilateral and bilateral occurrences noted.
Conclusions:
- The prevalence of Haller's cells is relatively low, consistent with global findings.
- Awareness of Haller's cells is vital for interpreting panoramic radiographs and preventing surgical complications during endonasal procedures.
