AI Article Synopsis
- The study investigates the effects of radiofrequency (RF) tonsillotomy on the characteristics of tonsils in patients with chronic tonsillitis through a case-control design.
- In a sample of 52 patients, tonsils were divided into two sections: one treated with RF and one left untreated for comparison.
- The results showed that RF treatment significantly reduced tonsil nodule size and mucosal thickness, with a notable decrease in Staphylococcus aureus bacteria in the RF group, suggesting RF has beneficial effects on tonsil tissue compared to the control group.
Article Abstract
Objectives: Tonsillotomy with radiofrequency (RF) is one of the newest treatments for chronic tonsillitis, but the mechanism of RF effects and complications are still pending. The aim of this study was to evaluate the effects of RF on the histological and bacteriological characteristics of the tonsils (Case-control study).
Materials And Methods: In fifty-two patients with chronic tonsillitis in 2017-2018, immediately after tonsillectomy, the tonsils were divided into 2sections; one sample treated with RF, and the other one considered as control, without intervention. All tonsil samples sent for histological and bacteriological study: morphometric assays made by Digitizer software, and type of bacterial colonies identified by microbiological and biochemical tests. Willcoxon and McNemar tests were used for statistical analysis and level of significance was p ≤ .05.
Results: Tonsil mucosal thickness (2202.98 ± 323.09 vs. 2463.94 ± 357.61 μm) and size of the tonsil nodule (28,000.42 ± 9608.75 vs. 36,692.81 ± 7040.74 μm) were significantly lower in the RF+ group than other group (p = .001 and p = .01, respectively). There was no significant differences in thickness of the tonsil epithelium (p = .075), number of lymphoid nodules (p = .860), and the number of reticular tonsil epithelium (p = .813) between the two groups. Bacterial growth in RF- and RF+ groups had no statistically significant difference (p = .06), however, the average colony count of S. aureus in RF+ tonsils were significantly lower, and total number of bacterial colonies were significantly lower in RF+ group(1405 ± 156 vs. 2471 ± 156), (p = .001).
Conclusion: RF surgery has significant effects on size of the nodules, thickness of the mucous layer and bacteriological characteristics of tonsil tissue. Especially S. aureus seems to be more sensitive to RF effects.

The purpose of this systematic review and meta-analysis was to identify the prevalence of synchronous contralateral tonsil carcinoma (SCTC) amongst patients with tonsil carcinoma or head and neck squamous cell carcinoma of unknown primary (HNSCCUP). Thirteen retrospective studies, comprising 2623 patients, were analysed, revealing an overall pooled SCTC prevalence of 4%, rising to 10% in HNSCCUP cases. HPV/p16 positivity was associated with SCTC prevalence of 3%, while HPV/p16 negativity was greater at 8%.

Background: Cancer immune responses are generated in secondary lymphoid organs, such as the lymph nodes and tonsils. In the current study, transcriptional profiles of peritumoral tonsillar tissues (PTTs) from oropharyngeal cancers (OPCs) were assessed and compared with those of inflammatory tonsils and regional lymph nodes (rLNs).
Methods: RNA samples of PTTs and rLNs from 13 OPCs, and 4 inflammatory tonsils were subjected to microarray analysis, and differentially expressed genes (DEGs) identified from 730 nCounter Panel immune-related genes.

Objectives: Tangier disease (TD) is a rare autosomal recessive condition characterized by high-density lipoprotein (HDL) deficiency; involving symptoms of polyneuropathy, hyperplastic orange-yellow tonsils, vision disorder, and sudden cardiac death. The major clinical symptoms of TD may not all be co-present. This study evaluates patients diagnosed with TD in childhood to improve the possibility of early diagnosis of asymptomatic cases by reporting our patients' clinical characteristics in order to minimize delayed diagnosis and emphasize the importance of TD, easily detected by HDL measurement.

<b>Introduction:</b> Deep neck infections (DNI) are potentially life-threatening conditions. The infections are commonly polymicrobial, and develop as a result of oral cavity infections, tonsilitis, laryngitis, trauma, or malignancy. Timely diagnostics and management are essential to prevent severe complications such as airway obstruction, sepsis or mediastinitis.
