Lingual Tonsil Hypertrophy in Patients With Allergic Rhinitis

Background Lingual tonsils, part of the Waldeyers’ Ring, are located in base of the tongue. They are commonly observed in childhood, due to increased immunological activity. Several factors such as laryngopharyngeal reflux, younger age, smoking, and obesity are associated with hypertrophy of lingual tonsils (LTH) in adulthood. However, the relation between allergic rhinitis and LTH is not clearly highlightened in the literature so far. Objective To investigate the role of allergic rhinitis in the development of LTH. Methods Adult patients who were diagnosed with allergic rhinitis were included in the study group. The control group consisted of age- and sex-match healthy volunteers. Complete otorhinolaryngology examination including fiberoptic endoscopic evaluation was performed to both groups. Blood samples were obtained for total immunglobulin E levels, and skin prick tests were performed to both groups. Patients with allergy complaints and positive skin prick tests were included in the study group, while healthy volunteers with negative skin prick tests were enrolled in the control group. The grading for LTH was achieved by a physician who was blind to the study. Results The incidence of LTH was significantly higher in the study group when compared to the control group (P = .001). Similarly, the incidence of grade 3 LTH was significantly higher in the study group compared to the controls (P = .002). Conclusion According to our results, LTH is more frequently observed in patients with allergic rhinitis. Grade 3 representing larger LTH is more commonly seen in patients with allergic rhinitis.
