introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...

OBJECTIVE/HYPOTHESIS Patients with laryngeal disorders often exhibit changes to cough function contributing to aspiration episodes. Two primary cough variables (peak cough flow: PCF and compression phase duration: CPD) were examined within a biomechanical model to determine their impact on characteristics that impact airway compromise. STUDY DESIGN Computational study. METHODS A Computation...

Analysis of published depth-kymography data [George, de Mul, Qiu, Rakhorst, and Schutte (2008). Phys. Med. Biol. 53, 2667-2675] shows that, for the subject studied, the flow due to the longitudinal sweeping motion of the vocal folds contributes several percent of a typical acoustic flow at the larynx. This sweeping flow is a maximum when the glottis is closed. This observation suggests that ass...

Voicing control in stop consonants has often been measured by means of voice onset time (VOT) and discussed in terms of interarticulator timing. However, control of voicing also involves details of laryngeal setting and management of sub- and supraglottal pressure levels, and many of these factors are known to undergo developmental change. Mechanical and aerodynamic conditions at the glottis ma...

Introduction: The major presenting symptom of nasal polyps is nasal obstruction. The role of nasal obstruction in the genesis of laryngeal disorders is still unknown.   Materials and Methods: The aim of this study was to evaluate laryngeal videostroboscopic changes after functional endoscopic sinus surgery (FESS) in patients with nasal polyposis. A longitudinal study was carried out from M...

Carbon dioxide (CO2) laser surgery as a conservative tool plays a peculiar role in the management of head and neck cancer. Numerous patients who were candidates for transoral laryngeal microsurgery have forced us to eliminate frozen-section evaluation of surgical margins and use a magnified view of the larynx. The present study evaluated surgeon-judged negative margins with permanent microscopi...

results the mean heart rate values were significantly less in the sevoflurane group (p value < 0.05) at 25 minutes after the surgery. the mean blood pressure in the isoflurane group was significantly higher compared with the sevoflurane group in 10, 20 and 30 minutes after the surgery (p values = 0.0131, 0.0373 and 0.0028, respectively). these differences were clinically unimportant because hea...

The efficacy of partial arytenoidectomy was assessed in 6 Standardbred horses, with surgically induced laryngeal hemiplegia, at rest (Period A) and during exercise at speeds corresponding to maximum heart rate (Period C) and 75% of maximum heart rate (Period B). Peak expiratory and inspiratory airflow rate (PEF and PIF), and expiratory and inspiratory transupper airway pressure (PUE and PUI) we...

introduction: laryngectomy in patients with laryngeal cancer can lead to the reduction of nutritional parameters. supportive treatments and supplementary nutritional supports are recommended in all patients undergoing laryngectomy, even with acceptable preoperative nutritional indices.the aim of this study was to evaluate postoperative changes in nutritional parameters in patients with laryngea...
