OBJECTIVES/HYPOTHESIS Describe the relationship between the magnitude of eustachian tube (ET) dilation during swallowing observed on transnasal videoendoscopy and quantified by sonotubometry. STUDY DESIGN Descriptive observational study. METHODS Simultaneous transnasal videoendoscopic and sonotubometric recordings were done on 33 adults with no middle ear disease. Briefly, microphones were ...

A total of 1,834 cases of colorectal cancers were divided into two diagnostic groups and studied. The ratio of smaller, less advanced carcinomas to the total number of colorectal cancers diagnosed by electronic videoendoscopy has increased as compared to the ratio in cases diagnosed by fiberscopy. This seems to be largely influenced by concomittent developments such as the implementation of col...

Narrow band imaging is considered a significant improvement in the possibility of detecting early mucosal lesion of the upper aerodigestive tract. Early detection of mucosal neoplastic lesions is of utmost importance for patients survival. There is evidence that, especially in patients previously treated by means of curative radiotherapy or chemoradiotherapy, the early detection rate of recurre...

OBJECTIVES Little is known about the function of the true vocal folds (TVFs) during cough. The objective of this study was to determine the reliability of measuring TVF movements during cough and to obtain preliminary normative data for these measures. METHODS Sequential glottal angles associated with TVF adduction and abduction across the phases of cough were analyzed from laryngeal videoend...

Objective. To assess the clinical parameters for successful uvulopalatopharyngoplasty in the management of obstructive sleep apnoea syndrome documented with pre- and postoperative polysomnography. Materials and Methods. A study group of 50 patients diagnosed as having OSA by full night polysomnography were assessed clinically and staged on basis of Friedman staging system. BMI and neck circumfe...

BACKGROUND Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. AIM To validate the morphol...

Accurate detection of the glottis in video sequences obtained during vocal cords examination using Laryngeal High-Speed Videoendoscopy (LHSV) is a prerequisite for calculation parameters describing cord kinematics. This work presents knowledge and methods related to determination region interest (ROI), which one important steps processing LHSV with aim automatic detection. ROI defined as area b...

Visualization of the entire length of the gastrointestinal tract through natural orifices is a challenge for endoscopists. Videoendoscopy is currently the "gold standard" technique for diagnosis of different pathologies of the intestinal tract. Wireless capsule endoscopy (WCE) has been developed in the 1990s as an alternative to videoendoscopy to allow direct examination of the gastrointestinal...
