“…In previous studies, Haller cells were unilateral in most cases [5,6,[9][10][11]. In the study by Solanki et al [6], from 192 Haller cells, 176 were unilateral, and 15 were bilateral, and the unilateral presence of Haller cells was statistically significant. In the study by Raina et al [9], from 96 Haller cells, 74 cases (77.1%) were unilateral, and 22 cases (22.9%) were bilateral, and unilaterality was statistically significant.…”

“…These cells are radiolucent and can be unilocular or multilocular with a smooth border which may or may not appear corticated, and are located medial to the infraorbital foramen [5]. The incidence of Haller cells has been reported to have a range from 2% to 45%, and often, they do not have any symptoms [6]. Haller cells have different sizes and can cause various complications.…”

Background and Aim: Haller cells are one of the anatomical variations in the orbital area, which are important in endoscopic surgical procedures and have a role in the pathogenesis of some diseases including sinusitis and chronic craniofacial pain. The frequency of Haller cells has been reported in a wide range, which can be attributed to several factors. The purpose of this study was to determine the frequency and anatomical characteristics of Haller cells. Materials and Methods: This descriptive study was performed on 381 patients referring to a private oral and maxillofacial radiology clinic during 2015-2017. These patients needed cone-beam computed tomography (CBCT) for various reasons. All CBCT scans were observed by a radiologist. The results were statistically analyzed by Chi-square test using SPSS version 16.0 software. Results: From 381 patients, 34 patients (8.9%) had Haller cells. Sixteen patients (47.05%) had Haller cells on the right side, 15 patients (44.11%) showed these cells on the left side, while 3 patients (8.82%) had these cells on both sides. On the right side, the oval shape showed the highest frequency (n=9; 47.3%). 36.8% and 15.7% of the right-sided Haller cells were round (n=7) and pyramidal (n=3), respectively. On the left side, the circular shape had the highest frequency (n=8, 44.4%). Furthermore, 27.7%, 16.7%, and 11.1% of the left-sided Haller cells were oval (n=5), pyramidal (n=3), and teardrop-shaped (n=2), respectively. Conclusion: The prevalence of Haller cells in our study was 8.9%. Genetic and racial factors, radiographic techniques, and the age range of patients are some of the reasons for different results.

This study aimed to determine the role of magnetic resonance imaging (MRI) in diagnosing and describing the characteristics of fistula-in-ano, and the agreement between MRI and operative findings. We conducted a retrospective study in 367 patients with fistula-in-ano who were diagnosed and had an operation at the University Medical Center between January 2016 and January 2018. MRI findings were evaluated and compared with surgical findings using the kappa coefficient (k) method. 367 patients (327 male and 40 female, mean age 39.3 ± 12.4 years). A total of 411 primary fistulas were found during surgery. There was a strong agreement between MRI and surgery for classifying primary tracts (k = 0.89) and detecting secondary tracts (k = 0.94). While the sensitivity and specificity of MRI for detecting internal openings were 99% and 85.2% respectively; these rates were 100% for abscesses. Both T2-weighted turbo spin-echo (T2W TSE) and postcontrast fat-saturated T1-weighted turbo spin-echo (FS T1W TSE) sequences showed high sensitivity (96.6% and 98.4% respectively) and specificity (92.6% and 81.5% respectively) for depicting internal openings and secondary tracts. Post-contrast FS T1W TSE sequence was very effective in detecting abscesses with an accuracy of 100%. In conclusion, MRI can be considered an accurate tool for the preoperative evaluation of fistula-in-ano, which is a major determinant of the surgical outcome. Both T2W TSE and post-contrast FS T1W TSE sequences are highly accurate in depicting the features of fistula-in-ano. If there are no contraindications, contrast administration is recommended to differentiate abscesses from active inflammation.
