Introduction: Oncocytic cysts of the larynx are benign, uncommon, and slow-growing lesions that usually occur in elderly people, especially those with a history smoking chronic irritation. These cause various clinical symptoms depending on their location size, requiring physicians to consider wide range symptoms. Case Presentation: Here we present two men who were referred us because prolonged ...

Understanding of dynamics of the speech production process may lead to a breakthrough in increasing the quality of synthesized voice and contribute to medical science with respect to treating voice disorder. However, little is known about mechanisms of speech dynamics, in particular about complex interactions of glottal flow and vocal fold vibration. In this paper, a two-dimensional viscoelasti...

Clinical Evaluation The clinical evaluation of liver mass lesions begins with a careful history and physical examination. Historical features will often give clues to the underlying diagnosis. For example a history of chronic hepatitis or the features or complications of liver cirrhosis is helpful in determining if individuals are at risk for hepatocellular carcinoma and intrahepatic cholangioc...

An experimental study of the vibratory deformation of the human vocal folds was conducted. Experiments were performed using model vocal folds made of soft silicone rubber, and an air supply system. The model self-oscillated at fundamental frequencies and flow rates typical of the human folds. Time-averaged mass flow rates and transglottal pressures were measured along with the sound pressure up...

Although the mammalian larynx exhibits little structural variation compared to sound-producing organs in other taxa (birds or insects), there are some morphological features which could lead to significant differences in acoustic functioning, such as air sacs and vocal membranes. The vocal membrane (or "vocal lip") is a thin upward extension of the vocal fold that is present in many bat and pri...

levels were evaluated in all patients. All assays were carried out in duplicate. Skin prick tests on the forearm were performed in all patients using standardized latex extract containing high ammonia natural rubber latex, and a full set of 35 common. In addition, venom SPT was performed on one patient based on the subject’s clinical history. Positive tests were counted as wheals of 3 mm in dia...

UNLABELLED Despite the growing experience obtained from the National Pro-Voice Campaigns in screening individuals with laryngeal alterations, we still have not established which would be the best assessment method: speech and hearing screening alone, laryngoscopy alone, or a joint work with physicians and speech therapists doing the screening together. AIM the goal of the present study was to...

BACKGROUND Recurrent laryngeal papillomatosis is caused by the human papilloma virus and characterized by multiple exophytic lesions of the vocal tract; it is a benign disease, but one that tends to recur after removal of growths. Due to the nature of the disease, alternative treatment strategies have focused on antiviral injection at lesion sites that eliminate repeated surgical procedures. Th...
