“…No significant difference between genders was reported in the previous studies [6,7,16,20,23,28,29]. The rate of tonsilloliths in males was found to be 41-51.2% in CT studies [3,7,8,12], 41-50.5% in CBCT studies [15][16][17], and 50.9-60.4% in PR studies [3,20,30]. The results of our study for both imaging techniques were in accordance with previous studies.…”

“…The prevalence of tonsilloliths in PR was found to be 5.7-13% in previous studies [4,6,20,21]. Retrospective 3-dimensional radiographic studies showed that the prevalence of tonsilloliths was found to be 16-46% by CT [3,7,8,12,[22][23][24] and 5-34% by CBCT [15,17,[25][26][27]. These differences may be due to differences in the demographics of the patients in these studies [3].…”

“…However, CBCT uses a significantly smaller radiation dose, slices images more thinly, and is less expensive compared to CT [13,14]. Although CBCT has limited soft tissue imaging capacity, tonsilloliths can be determined on 3-dimensional CBCT images [15][16][17]. Ultrasonography can also be used for the detection of soft tissue calcifications [18].…”

Significance of the Study• The aim of this study was to compare cone-beam computed tomography (CBCT) and panoramic radiography (PR) for the detection of tonsilloliths. • The detection rate of tonsilloliths was 33.2% on CBCT. • Only 51.4% of the tonsilloliths detected on CBCT were identified by PR. • PR was not adequate to detect tonsilloliths 1 mm or smaller in size. AbstractObjective: A tonsillolith is a concretion of the tonsillar crypt. The aim of this retrospective study was to compare panoramic radiography (PR) and cone-beam computed tomography (CBCT) for the detection of tonsilloliths. Materials and Methods: The CBCT images of 527 patients with maxillofacial volume were evaluated retrospectively. Of these, 175 patients (81 females, 94 males; mean age 51.05 years) had unilateral or bilateral tonsilloliths. In total, 151 of them (67 females, 84 males; mean age, 51.03 years) had PR images performed in the same period and were included in the study. The PR images were examined to ascertain whether known tonsilloliths (from CBCT images) could be detected. The location (unilateral; left or right and bilateral), size, and number of the tonsilloliths were examined on both CBCT and PR images. Descriptive analysis, Spearman's rho correlation coefficient, and χ 2 tests were used for the statistical analysis. Results: The detection rate of tonsillolith was 33.2% on CBCT images. Only 51.4% of the tonsilloliths detected on CBCT were evaluated by PR; the correlation between CBCT and PR was found to be significant (Spearman's r = 0.399, p = 0.000). PR was not adequate to detect tonsilloliths 1 mm or smaller in size. All the calcifications larger than 5 mm were detected on PR images. Conclusion: The results of this study showed that more than half of the tonsilloliths observed in CBCT were also detected in PR. Tonsilloliths larger than 2 mm were more likely to be detected on PR images.

“…This structure was the second most commonly mineralised ligament (18.3%), which is higher than some studies of dry skulls (1.4–9%) [ 18 , 49 ], but comparable to prior radiographic and CT studies [ 16 , 23 , 46 ]. This likely reflects the superiority of imaging in detecting fine calcified structures that may not be preserved in dry skulls.…”

Skull base ligamentous mineralisation: evaluation using computed tomography and a review of the clinical relevance

et al. 2019

Objectives To determine the frequency, morphologic and demographic characteristics, and clinical relevance of the mineralisation of six skull base ligaments (interclinoid, caroticoclinoid, petrosphenoid, posterior petroclinoid, pterygospinous, and pterygoalar). Methods This is a retrospective review of 240 CT scans of the paranasal sinuses (ages 6–80 years). A limited systematic review was performed primarily using Embase and Medline databases. Results Ligamentous mineralisation was well delineated on CT and occurred at ≥ 1 location in 58.3% of patients. There was a nonsignificant trend towards a greater incidence with advancing age. The interclinoid and posterior petroclinoid ligaments were most commonly mineralised (22.1% and 18.3%, respectively); the petrosphenoid and pterygoalar ligaments were least frequently mineralised (10.8% and 6.3%, respectively). The mean age of patients with posterior petroclinoid mineralisation was significantly greater than those with interclinoid and petrosphenoid mineralisation and was not seen in patients aged 6–20 years. The literature review highlighted the clinically relevant potential for mineralised ligaments to cause barriers to surgical access (e.g. to the foramen ovale), increase the risk of neurovascular injury during surgery at the skull base (e.g. during anterior clinoidectomy), and predispose to neural impingement. Conclusions Skull base ligamentous mineralisation is commonly encountered on CT imaging. Given the potentially significant clinical implications, an understanding of the morphological appearances is of importance to those planning interventions at the skull base. To the authors’ knowledge, this study is the first to comprehensively evaluate such a wide range of skull base ligaments using CT. For some ligaments, the incidence on CT has not been previously described.
