Glottal insufficiency (GI) is a cause of breathy voice that can profoundly affect quality of voice. Main causes are unilateral vocal fold paralysis or endoscopic cordectomy for the early treatment of laryngeal cancer of the glottis. The main strategy in surgical treatment is type I medialization thyroplasty according to Isshiki with the use of implants e.g. silastic, hydroxyapatite, titanium, Gore-Tex or Montgomery. Other procedures are arytenoid adduction, the injection laryngoplasty via thyrohyoid and cricothyroid approach and laryngeal reinnervation...

OBJECTIVE: To observe the effect of endotracheal tube with subglottic suction line on tracheostomy bleeding in critical patients. METHODS: This procedure was utilized for 35 critical patients with tracheostomy bleeding. With the help of bronchoscope, the endotracheal tube with subglottic suction line was inserted during tracheostomy to 0.5-1.0 cm above the carina. Then aerocyst of the tube was inflated, vacuum was set up for continuous suction via suction port, and hemocoagulase was injected to the opening of tracheostomy...

An 85-year-old woman was brought to an accident and emergency department with breathing difficulties accompanied by inspiratory stridor. She was being treated for hypertension and severe osteoporosis which had caused thoracal and cervical fractures of the columna. Intubation was initiated as she desaturated and deteriorated despite maximum oxygen therapy. The intubation revealed a subglottic stenosis as a consequence of a recent osteoporotic fracture in the cervical columna. This represents a rare cause of respiratory failure as all other cardial, pulmonary and allergic aetiologies had been eliminated...

Gastroesophageal reflux disease affects more than 10% of the adult population. Most patients can be effectively treated with lifestyle changes and adequate acid-reducing therapy. However, about 10% of the patients remain symptomatic despite treatment and severe complications may develop. Interestingly, some of these complications seem to be a sort of defensive mechanism that may either alleviate the patient's symptoms or prevent developing further complications. In Barrett's esophagus, which can be unambigously considered as a complication of gastroesophageal reflux disease, reflux symptoms ruining the quality of life may significantly improve, since the metaplastic Barrett epithelium is much more resistent to gastric acid, than the normal epithelial lining of the esophagus...

Jinxi Guo, Ruochen Yang, Harish Arsikere, Abeer Alwan
This letter investigates the use of subglottal resonances (SGRs) for noise-robust speaker identification (SID). It is motivated by the speaker specificity and stationarity of subglottal acoustics, and the development of noise-robust SGR estimation algorithms which are reliable at low signal-to-noise ratios for large datasets. A two-stage framework is proposed which combines the SGRs with different cepstral features. The cepstral features are used in the first stage to reduce the number of target speakers for a test utterance, and then SGRs are used as complementary second-stage features to conduct identification...

Biao Geng, Qian Xue, Xudong Zheng
A finite element method based numerical indentation technique was used to quantify the effect of the material stiffness variation and the subglottal convergence angle of the vocal fold on the vertical stiffness difference of the medial surface. It was found that the vertical stiffness difference increased with the increasing subglottal angle, and it tended to saturate beyond a subglottal angle of about 50°. The material stiffness variation could be as important as the subglottal angle depending on the actual material properties...

Foreign bodies in the upper respiratory tract are one of the most difficult otolaryngological emergencies; leeches are a very rare foreign bodies in the world. We report the case of a 70-year-old man with no past medical history presenting with laryngeal dyspnea associated with low abundant paroxysmal hemoptysis. The patient underwent nasofibroscopy showing the presence of a living and mobile organism at the subglottic level evoking a leech. Extraction was carried out under local anesthesia using laryngoscope and Magill forceps...

This case report illustrates how a multinodular goitre caused acute airway obstruction in a multitrauma 66-year-old male after tracheotomy. The patient had no symptoms of the goitre before the tracheotomy but developed subglottic airway obstruction at the time of decannulation. He underwent a subacute total thyroidectomy which removed the obstructive symptoms. A weakening of the tracheal tube followed by the tracheotomy possibly caused the tracheal stenosis in combination with the goitre.

BACKGROUND: The anterior commissure (AC) of the human larynx is usually understood as an area of the glottis anteriorly situated between the two vocal folds inserting to the thyroid cartilage (TC). The pattern of spread of AC carcinoma could hypothesize that AC could include other structures of the ventral larynx as developmental anatomy could demonstrate. METHODS: Ten adult larynx specimens from donation program cadavers and 15 selected fetal specimens (from 11 to 34 weeks of amenorrhoea) were studied using microdissection and histological serial sections stained with hematoxylin-eosin and reticuline...
