RESUMO
OBJECTIVE: The hyperplasia of the lingual tonsil is a rare and at the same time potentially dangerous change in the area of the upper respiratory tract. The pathogenesis of the lingual tonsillar hyperplasia is still largely unknown. In this study, we investigated if there is a compensatory lingual tonsil hyperplasia after tonsillectomy. MATERIAL AND METHODS: 300 patients were examined consecutively in the ENT clinic of the Hannover Medical School. In the context of indirect laryngoscopy, the lingual tonsil, the visibility of the larynx and its subregions were assessed according to a scheme. The data were then evaluated depending on the status of the palatal tonsils. In addition, the body mass index (BMI) was determined and compared with the results of laryngoscopy. RESULTS: Out of 300 patients, 89 (29.6%) were in condition after bilateral tonsillectomy. In the total population, a greatly enlarged lingual tonsil was only detectable in 14 cases (4.6%). Of these 14 patients, 4 had a history of tonsillectomy. In patients with severe lingual tonsil hyperplasia the mean BMI was 27.3 compared to 24.4 in patients with a normal lingual tonsil. CONCLUSION: In our population the incidence of severe lingual tonsil hyperplasia is 4.7%. We couldn't prove s a connection between a condition after tonsillectomy and compensatory lingual hyperplasia statistically. However, there was a significant relationship between BMI and lingual tonsil hyperplasia.
