Abstract :

Objectives: Haller�s cells or infraorbital ethmoid cells represent the ethmoidal pneumatization of the superior aspect of the maxillary sinus and floor of the orbit. The clinical importance of these prompted this study with an objective to reveal the occurrence and characteristics of Haller�s cells on panoramic radiographs.

Methods: The study group consisted of 250 healthy adult subjects of any gender in the age range of 18-60 years. Panoramic radiograph was taken and inferred for the occurrence of Haller�s cells for each patient. The data collected was submitted for statistical analysis: Frequencies/percentages, Descriptive Statistics, Chi-square test and Cross tabulation (contingency table analysis) to obtain the results.

Results: Haller�s cells were seen in 42 subjects accounting for a prevalence of 16.8%. Of these, 71.4% were unilateral while 28.5% bilateral. Most of the cells were round or ovoid in shape. Unilocular type of Haller�s cells seen unilaterally was statistically significant.

Conclusions: This study has endeavored to discover the characteristics of Haller�s cells on panoramic radiographs. A depiction of Haller�s cells on these radiographs may prove vital in enumerating the differential diagnosis for patients afflicted with intractable oro-facial pain and reduce the risk of untoward intraoperative complications during endonasal procedures.
