“…Ultrasonography can also be used for the detection of soft tissue calcifications [18]. In the literature, it was reported that tonsilloliths could be diagnosed by an intraoral transducer [19]. Ultrasonography has some limitations, such as patient discomfort and difficulty of use [19].…”

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.

“…Previous studies reported that the detection of palatine tonsilloliths varies, and the prevalence in CT is 16.0-46.6% and in panoramic radiographs -7.3-13.4% only [7]. Two-dimensional image, superimposition of structures, distortion, and magnification may be diagnostic challenges in interpretation of panoramic radiographs [2,9,13,19]. The detection of TLs in panoramic radiographs might be related to their amount, degree of calcification, or size [4].…”

“…They may be asymptomatic or cause dysphagia, globus sensation, halitosis, otalgia, peritonsil-lar abscess, swelling in the tonsillar fossa, glossopharyngeal neuralgia, orofacial pain, upper airway obstruction, and sleep breathing disorders. They may be incidentally found in three-and two-dimensional radiological examinations [1][2][3][4][5][6][7][8][9][10][11][12][13]. TLs appear as small opacities, overlapping the middle portion of mandible ramus, or as multiple poorly defined radio-opacities, which may be oval, round, or irregular in shape, superimposed on the soft tissues' shadows.…”

Introduction: Calcifications found in the crypts of palatal tonsils, called tonsilloliths, are considered an incidental finding in panoramic radiographs. Dentists and radiologists should be aware of their radiological appearances in order to avoid diagnosis of different calcifications. Objectives: The objective of the research was to examine the prevalence and characteristics of tonsillar calcifications visible in panoramic radiographs in a sample of Polish population. Material and methods: The study included one thousand consecutive digital dental panoramic radiographs taken with Planmeca Prostyle X-ray machine in 577 females and 423 males aged from 5 to 88 years. The presence of tonsilloliths, their characteristics (single or multiple) as well as localization according to 6 regions (1-3 shadows cast on the mandibular ramus above, at and below the level of soft palate, 4-below mandible, 5-below and posterior to mandibular angle, 6-posterior to mandibular ramus) were assessed. Results: Tonsilloliths were detected in over 24% of panoramics. Prevalence in females and males was comparable. Findings were more prevalent in the following age groups: 30-39 years, 50-59 years (37.5%), and 40-49 years (35%). They were far less frequent in patients below 30 years of age. Tonsillar calcifications were found in 511 regions in 242 patients, and in 116 cases they were single. Almost 30% of calcifications were detected in region 2 and 25% in region 3. Over 65% of tonsilloliths were found bilaterally. Conclusions: Tonsilloliths are frequent incidental finding in X-rays. About one-quarter of analyzed panoramics revealed the presence of stones.

“…There have been several conflicting definitions of tonsilloliths in the literature. Many studies emphasize that tonsilloliths are calcified concretions [1][2][3][4][5][6][7][8]13,19 ; however, calcification is not necessary for a concretion to be considered a tonsillolith. This is evidenced by only 12% of patients with tonsilloliths exhibiting calcification ( Table 3).…”

Objective To better characterize associations between Actinomyces and tonsillolith versus nontonsillolith tonsillectomy specimens. Study Design Bi-institutional retrospective case-case study. Setting University and county hospital. Subjects and Methods Adult patients with a clinical history of tonsilloliths who underwent tonsillectomy from January 2006 to December 2018 were included. Patients undergoing tonsillectomy for tonsillar hypertrophy and chronic tonsillitis were identified as comparative cases. Similarly, patients with ipsilateral oropharyngeal cancer (OPC) who underwent contralateral tonsillectomy of a normal-appearing tonsil for prophylaxis against a second primary cancer were also included as comparative cases. Results The study population comprised 134 patients who underwent tonsillectomy: 62 tonsillolith and 72 nontonsillolith (tonsillar hypertrophy, n = 30; chronic tonsillitis, n = 30; normal-appearing contralateral tonsil in patients with ipsilateral OPC, n = 12). Actinomyces was reported in 11% of the patients with tonsilloliths on initial pathology reports but in 95% after re-evaluation (n = 54 of 57). Actinomyces prevalence was significantly higher in patients with tonsilloliths as compared with patients with recurrent tonsillitis (73%, n = 22 of 30, P < .001) and normal-appearing contralateral tonsils in patients with ipsilateral OPC (58%, n = 7 of 12, P < .001). Actinomyces prevalence was not significantly different between patients with tonsilloliths and tonsillar hypertrophy (83%, n = 25 of 30, P = .11). Conclusion The prevalence of Actinomyces in tonsillolith tonsil specimens is high; however, Actinomyces routinely colonizes nontonsillolith tonsil specimens. Therefore, Actinomyces is unlikely to be the primary driver of tonsillolith pathogenesis, and Actinomyces-targeted treatment of tonsilloliths may not be effective. Treatment strategies addressing tonsilloliths should be further investigated.
