Shared airway management in patients with subglottic stenosis (SGS) is challenging for both the anaesthetist and surgeon. Various methods of airway management have been described but currently no gold standard exists. Jet ventilation has been described as the preferred technique despite a UK National Survey highlighting potential complications including pneumothorax, pneumomediastinum, surgical emphysema, hypoxia and death.

OBJECTIVES: Subglottic stenosis is an abnormal narrowing of the tracheal lumen at the level of subglottis (the area in between the vocal cords and the cricoid cartilage). It can cause significant symptoms due to severe attenuation of airflow. We describe our experience in alleviating symptoms by addressing the stenosis using fibreoptic bronchoscopic methods. METHODS: We report all concurrent cases performed between September 2015 and July 2016. We use a combination of balloon dilation, electro-surgery knife to dilate and incise stenotic segments followed by steroid injection to modulate healing...

BACKGROUND: Transoral robotic surgery total laryngectomy (TORS-TL) is a minimally invasive endoscopic surgical approach which can theoretically minimise the morbidity of large external incisions and limit dissection of tissue planes so as to reduce the risk of pharyngocutaneous fistulae related to poor tissue healing secondary to radiation soft tissue injury or malnutrition. The purpose of this paper was to report our experience with this uncommon surgical approach. METHODS: A retrospective chart review was conducted at a single institution to evaluate the functional and survival outcomes of a series of patients who underwent TORS-TL...

Among vocal fold diseases, the presence of a surface growth is often encountered and can be considered a public health issue. While more energy is required to achieve phonation than in healthy cases, this situation can lead to a wide range of voice perturbations, from a change of voice quality to aphonia. The present study aims at providing finer comprehension of the physical phenomena underlying this type of pathological phonation process. A vocal fold replica is used to perform measurements of mechanical responses of each vocal fold as well as of the subglottal pressure in both healthy and pathological configurations...

OBJECTIVE: A recently published retrospective chart review of aerodynamic profiles of women with primary muscle tension dysphonia by Gillespie et al (2013) identified various relationships between mean airflow rate (MFR) and estimated subglottal pressure (est-Psub). The current retrospective study expanded the diagnostic categories to include all voice disorders referred for voice therapy. Three research questions were proposed: (1) Are there differences in the MFR and the est-Psub compared with the normal control group? (2) Within the disordered population, are there different variations in the pairing of MFR and est-Psub? (3) If these variations exist, are they diagnosis specific? METHODS: A retrospective chart review of patients seen for acoustic and aerodynamic voice assessment at the Emory Voice Center between January 1, 2013 and December 31, 2014, were examined for aerodynamic measures of est-Psub and MFR; of these, 192 met the inclusion criteria...

OBJECTIVES/HYPOTHESIS: Current treatment options for idiopathic subglottic stenosis include endoscopic interventions, resection, and tracheotomy. Recently, serial office-based steroid injections were proposed as an alternative that may stabilize or induce regression of airway stenosis without the need for repeated operations. Procedure completion rate, pain, complications, effect on stenosis, time since the last operation, and limitations have not been described. STUDY DESIGN: Retrospective case series...

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...

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...
