INTRODUCTION The aim of this study was to compare the precision and accuracy of 6 imaging software programs for measuring upper airway volumes in cone-beam computed tomography data. METHODS The sample consisted of 33 growing patients and an oropharynx acrylic phantom, scanned with an i-CAT scanner (Imaging Sciences International, Hatfield, Pa). The known oropharynx acrylic phantom volume was ...

BACKGROUND Human papillomavirus (HPV), the causal agent of cervical cancer, appears to be involved in the etiology of cancer of the oral cavity and oropharynx. To investigate these associations, we conducted a multicenter case-control study of cancer of the oral cavity and oropharynx in nine countries. METHODS We recruited 1670 case patients (1415 with cancer of the oral cavity and 255 with c...

We investigated the nasopharynx and oropharynx microbiota in sickle cell disease (SCD) to identify the microorganisms, antibiotic sensitivity, prevalent serotypes, and association of with laboratorial markers. Oropharynx/nasopharynx secretions were investigated in 143 SCD children aging 6 months to 17 years. Pathogens were isolated using standard procedures, and laboratorial markers were perfor...

Haemangiopericytoma (HPC) is a rare vascular tumor arising from the pericytes of Zimmermann and is characterized by its unpredictable and variable biological behavior. These tumors are common in the trunk and the extremities and less than 16% of the cases occur in the head & neck region. Its occurrence in the oral cavity and pharynx is uncommon. We report an extremely rare case of haemangioperi...

OBJECTIVES The purpose of study was to determine the clinical efficacy of primary tumor volume measurements of different primary sites in the oropharynx compared to the oral cavity. METHODS A retrospective analysis of 85 patients with oral cavity or oropharynx cancer. The tumor area was manually outlined from axial magnetic resonance (MR) series. The software calculated the tumor volumes, aut...

PATIENT A case of Turner's syndrome developing a leiomyosarcoma of the oropharynx and metachronous neurogenic tumors (mediastinal 'ganglioneuroblastoma intermixed', subcutaneous neurilemoma) is described. DISCUSSION To our knowledge, this case is the second reported leiomyosarcoma in a patient with Turner's syndrome. Also the site of involvement (palate and oropharynx) is particularly unusual...
