“…The radiographs obtained were serially interpreted for the presence of Haller's cells under ideal viewing conditions. The recognition of Haller's cells was made if an anatomical variation fulfilled the criteria suggested by Ahmad et al 2 The observations pertaining to the Haller's cells were entered in the subjects' proformas. The data collected were tabulated and subjected to statistical analysis, namely frequencies/percentages, descriptive statistics, x 2 test and cross-tabulation (contingency table analysis) using SPSS for Windows (SPSS Inc., Chicago, IL) to obtain the results.…”

“…1 Haller's cells, first described by the Swiss anatomist Albert von Haller in 1765, are also known as maxillo-ethmoidal or orbito-ethmoidal cells. 2,3 Haller's cells are thought to arise in individuals with pneumatization of the lateral crus. 4 Although Haller's cells are anatomical variations in the development of the nose and paranasal sinuses, they have been held responsible for patient's symptoms and are thus clinically significant.…”

“…4 Although Haller's cells are anatomical variations in the development of the nose and paranasal sinuses, they have been held responsible for patient's symptoms and are thus clinically significant. 1,2 In addition to distressing orofacial pain and sinusitis, numerous pathologies and symptoms associated with this entity include nasal obstruction, impaired nasal breathing, headache, chronic cough and mucoceles. 2,3,[5][6][7][8] Haller's cells can also restrict access to the maxillary sinus or the anterior ethmoidal cells during endonasal procedures, making it imperative for the surgeon to be aware of such variations that may incline the patient to increased risk of intraoperative complications.…”

Objective: Haller's cells or infraorbital ethmoid cells refer to the ethmoidal pneumatization of the superior aspect of the maxillary sinus and floor of the orbit. The clinical importance of these entities initiated this study with an aim to determine the prevalence and characteristics of Haller's cells on panoramic radiographs. Methods: The study group comprised 600 healthy adults of both genders with an age range of 18-60 years. One panoramic radiograph for each of the patients was made and interpreted for the presence of Haller's cells. The data collected were subjected to statistical analysis: frequencies/percentages, descriptive statistics, x 2 test and cross-tabulation (contingency table analysis) to obtain the results. Results: Haller's cells were noted in 96 patients, accounting for a prevalence of 16%. Of these patients, 77.1% were unilateral while 22.9% were bilateral. Among 96 cases, a total of 204 cells were found. The majority of the cells were round or ovoid in shape. The unilocular type of Haller's cells occurring unilaterally was statistically significant. Conclusion: This study has attempted to explore the characteristics of Haller's cells on panoramic radiographs. A description of Haller's cells on these radiographs may prove vital in enumerating the differential diagnosis for patients afflicted with intractable orofacial pain and reduce the risk of untoward intraoperative complications during endonasal procedures.

MRI has been usually used to obtain information from the soft tissue of the TMJ especially for evaluating the articular disc and its pathology. Even if small field of view (FOV) and surface coils are used in TMJ MR imaging, it should be expected that some incidental findings may appear outside the primary area of interest. These incidental findings are common in TMJ MRIs. Orhan et al. [1] evaluated the incidental findings in TMJ MRI and found 117 incidental findings in 15% of the patients. K. Orhan et al.
