OBJECTIVE To compare the effectiveness of the telovelar approach with tonsillar manipulation for approaching the recesses of the fourth ventricle. METHODS A telovelar approach was performed in 8 injected cadaveric heads. Areas of exposure were measured for the superolateral and lateral recesses. Horizontal angles were evaluated by targeting the cerebral aqueduct and medial margin of the later...

metastasis from a malignant tumor to the palatine tonsils is rare, accounting for only 0.8% of all tonsillar tumors, with only 100 cases reported in the english-language literature. various malignant lung carcinomas may metastasize to the tonsils. a few cases of tonsillar metastasis from neuroendocrine lung carcinoma have been reported. a 67-year-old female underwent a right tonsillectomy becau...

conclusion our results concerning cranium morphometry support the theory that hypoplastic posterior cranial fossa due to mesodermal insufficiency may play a role in the etiology of tonsillar herniation. results in individuals with tonsillar herniation, while the front-back diameter of the foramen magnum, the cerebellum height, and the sagittal diameter of the cerebellum increased, the maximum c...

The usefulness of tonsillar biopsy on live deer for preclinical diagnosis of the transmissible spongiform encephalopathy chronic wasting disease (CWD) was evaluated. Disease was tracked in a CWD-endemic herd using serial tonsillar biopsies collected at 6 to 9 month intervals from 34 captive mule deer (Odocoileus hemionus) and five white-tailed deer (O. virginianus). Tonsillar biopsies were exam...

Tonsillectomy in children is performed on a regular basis in ENT. The indications are chronic tonsillitis, sleep apnea to deeper structures. The natural history of tonsillar hyperplasia is regression when a child is six years beyond. In children with bilateral tonsillar hyperplasia we studied the use of laser as an alternative procedure to reduce the bulk of the tonsillar mass. Children with sy...

A clinical analysis of 6 patients with pathologically confirmed tonsillar tuberculosis was carried out retrospectively. The subjects comprised three men and three women, ranging in age from 20 to 74 years. All of the patients presented with a sore throat and 5 had lymphadenopathy. Ulcerations, masses and white patches characterized the tonsillar lesions; the pathological findings included caseo...

BACKGROUND The purpose of this study was to determine whether the incidence of bilateral neck disease tonsillar cancer is rising. METHODS We reviewed tonsillar cancer incidence data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute. RESULTS The annual incidence of advanced neck disease (≥N2) with small primary tonsillar cancer is increasing...

The purpose of this article is to review the current knowledge on the status and significance of human papillomavirus (HPV) in tonsillar cancer. Current data in scientific reports and data from the Karolinska Hospital and Karolinska Institute, Sweden, demonstrate that approximately half of all tonsillar cancer is HPV-positive. Moreover, patients with HPV-positive cancer have a lower risk of rel...

BACKGROUND There is an ongoing controversy about the significance of tonsillar ectopia among patients with idiopathic scoliosis (IS). AIM To find out if tonsillar ectopia occurs more frequently among patients with IS and if it plays any etiological or prognostic role in IS. STUDY DESIGN Retrospective study. METHODS Retrospective analysis of 155 consecutive spine MRIs (79 patients with IS ...

Lymphoproliferative responses of tonsillar tissue lymphocytes and peripheral blood lymphocytes to phytohemagglutinin and specific bacterial product antigens were studied in children undergoing tonsillectomy and adenoidectomy. Tonsillar tissue lymphocytes responded to optimal concentrations of phytohemagglutinin. Varidase, and streptolysin-O in a manner similar to peripheral blood lymphocytes. H...
