Using fibreoptic laryngoscopy to observe pharyngeal articulations, the aryepiglottic sphincter mechanism i s shown to be responsible for the production of speech sounds in the phonetic category "pharyngeal." Major differences in auditory/acoustic quality are also produced when the larynx as a whole is raised or lowered during the production of pharyngeals. The voiceless pharyngeal fricative and...

We examined pharyngeal nerve courses in paraffin-embedded sagittal sections from 10 human fetuses, at 25-35 weeks of gestation, by using S100 protein immunohistochemical analysis. After diverging from the glossopharyngeal and vagus nerves at the level of the hyoid bone, the pharyngeal nerves entered the constrictor pharyngis medius muscle, then turned upward and ran superiorly and medially thro...

By use of molecular techniques, the genetic heterogeneity of 63 community pediatric pharyngeal group A streptococcal (GAS) isolates circulating within a 3-week period were compared with 17 contemporaneous invasive pediatric isolates. Pharyngitis isolates represented 16 pulsed-field gel electrophoresis (PFGE) patterns with 12 emm serotypes, and invasive isolates represented 10 PFGE patterns with...

From a fiberscope, the tip of which was swung from left to right in the pharynx, cinefilm frames were obtained which showed the cross-sectional shape of pharyngeal constrictions in back vowels. This information was combined with the information offered by X-ray pictures of the same subject phonating the same vowels on a different occasion. The results agree to a reasonable extent with previousl...

BACKGROUND Acoustic reflectometry is a relatively new technique that quantifies upper airway obstruction. The oropharyngeal airway is geometrically complex and variable; therefore establishing a standard operating protocol and understanding the possible sources of artifacts are of great importance in obtaining reliable results. This work aims at assessing the repeatability of pharyngeal cross-s...

Most patients complaining of pharyngeal pain have an upper respiratory tract infection or other local explanation for their pain. Here we show 3 rare cases of patients visiting our Otorhinolaryngology Department who had an initial symptom of pharyngeal pain caused by acute coronary syndrome (ACS). An electrocardiogram and a cardiac biomarker test are recommended to exclude ACS with atypical pre...

UNLABELLED High pressure of pharyngo-esophageal segment is the most important factor of impaired development of alaryngeal speech (esophageal speech, tracheoesophageal speech) after total laryngectomy. To prevent pharyngo-esophageal spasm in Department of Otolaryngology in Szczecin are used: pharyngoesophageal plastic surgery with interposition of vascular thyroid flap, two-layer (only mucosa) ...

OBJECTIVES/HYPOTHESIS Robotic surgery has significant potential in pharyngeal and microlaryngeal surgery. We demonstrate the use of a surgical robot in pharyngeal and microlaryngeal surgery in a cadaver. STUDY DESIGN Six experimental surgical dissections, modeled after commonly performed pharyngeal and microlaryngeal procedures, were performed in a cadaver with a commercially available surgic...

Objective Evaluation of causes, therapy and influence comorbidity postoperative complications in patients with pharyngeal proximal esophageal perforations (PHP).
