Infraorbital ethmoid (Haller's) cells: a panoramic radiographic study

Abstract

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.

Prevelance of Haller’s Cells: A Panoramic Radiographic Study

“…No statistically significant differences were noted in the occurrence of Haller's cells on the right and left side, which were 69 and 73 cells respectively. Similar findings were seen in study conducted by A Raina et al, [9].…”

“…In the present study analyses have been performed to determine the variations of Haller's cells with respect to gender, age, number, type and shape which were remotely been reported in the past. A study conducted by A Raina et al, [9] have reported the prevelance of hallers cells of 16% which lies in the same range as that of this study. Maximum number of cells between males and females which was consistent with the findings of N Basic et al, [10].…”

Osteomeatal Complex: A Study of Its Anatomical Variation Among Patients Attending North Bengal Medical College and Hospital

“…This result is similar with the study conducted by Riello and Boasquevisque, Zeinrich et al who found 10 % Haller cell in their study [20,21]. Raina et al noted 16 % of the study population possesses Haller cell [22]. Mamatha et al documented 17.5 % Haller cell in their study [16].…”

Frequency and volumetry of infraorbital ethmoid cells (Haller cells) on cone-beam computed tomograms (CBCT) of the mid-face

“…This result is contrary to former surveys [37], [38], [39]. As CBCT delivers detailed information on the ethmoid complex with lower costs compared to CT and the possibility of prompt information by implementation in an outpatient office [28], [29], we see further need for radiological investigation and clinical studies on Haller cells.…”
