The feasibility of computational fluid dynamics (CFD) to evaluate airflow characteristics in different head and neck positions has not been established. This study compared the changes in volume and airflow behavior of the upper airway by CFD simulation to predict the influence of anatomical and physiological airway changes due to different head-neck positions on mechanical ventilation. One awake volunteer with no risk of difficult airway underwent computed tomography in neutral position, extension position (both head and neck extended), and sniffing position (head extended and neck flexed)...

PURPOSE OF REVIEW: The aim of this study was to describe the most recent technical nuances for resection and reconstruction of Grade 1 and 2 laryngeal chondrosarcomas, with a special emphasis on those located at the level of the cricoid plate, which is the site of origin of the vast majority of these rare tumours. RECENT FINDINGS: Even though inherently based on retrospective small clinical series or anecdotal case reports, a number of studies have been recently published focusing on conservative transoral and open-neck surgical procedures aimed at an oncologically sound removal of the tumour together with organ and function preservation...

Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country...

Tuberculosis (TB) is among the top infectious causes of morbidity and mortality worldwide and is associated with frequent pulmonary damage despite microbiological cure. Patients with treated TB may remain lifelong sufferers of disabling structural and functional sequelae of the disease, which subsequently impair quality of life. Long-term follow-up studies have revealed that many patients with treated pulmonary TB show signs of permanent impairment of their lung function. Impairment is variable in pattern and severity, ranging from none to severe, and shows restrictive, obstructive, or mixed patterns...

Large cell neuroendocrine carcinoma is a rare high-grade neuroendocrine neoplasm of the larynx, that exhibits particularly aggressive behaviour. We present a case of a 42-year-old patient with progressive dyspnoea and biphasic stridor, initially treated as asthma and resulting in delayed definitive management. Flow volume loops demonstrated narrowed inspiratory and expiratory flow volume loops. Subsequent CT neck and thorax indicated a mass arising from the subglottis and the patient proceeded to microlaryngoscopy and trans-oral CO2 laser debulking...

We present a case of impassable subglottic stenosis scheduled for tracheal resection and reconstruction managed by establishing a supraglottic airway. Despite careful preoperative evaluation, the stenosis was localized higher than anticipated, rendering conventional intubation impossible. Laryngeal mask bridging to cross-field ventilation was feasible and jet ventilation and cardiopulmonary bypass were available as emergency strategies. Surgery and emergence went uneventful. Perioperative considerations are discussed in this report...

OBJECTIVE: The aim of this study was to determine if external subglottic air flow (ESAF) influences swallowing frequency in severely dysphagic tracheotomized patients with brain injury. METHODS: Ten patients were recruited at the neurological intensive care unit. The ESAF intervention was provided through the standard cuffed suction aid tracheotomy tube, which primarily is used to suction residual secretion volume from the subglottic area. Sessions were 150 minutes, and ESAF was provided at 60-65, 90-95, and 120-125 minutes at 3 L/min...

Hypercapnia produces active expiration in rats and the recruitment of late-expiratory (late-E) neurons located in the parafacial Respiratory Group (pFRG) of the ventral medullary brainstem. We tested the hypothesis that hypercapnia produces active expiration and concomitant cranial respiratory motor responses controlling the oropharyngeal and upper airway patency by pFRG late-E neurons disinhibition, but not via synaptic excitation. Phrenic nerve, abdominal nerve (AbN), cranial respiratory motor nerves, subglottal pressure, and medullary and spinal neurons/motoneurons were recorded in in situ preparations of juvenile rats...

Difficulty during placement of the tracheal tube is a known problem when intubating with the GlideScope(®) , which may lead to subglottic airway injury. This randomised, controlled clinical trial was designed to compare the resistance to passage of PVC (polyvinyl chloride), reinforced or BlockBuster tracheal tubes during intubation with the GlideScope. Secondary outcomes included the time taken to intubate and assessment of subglottic airway injury. One-hundred and seventy-seven patients were included in the data analysis...

BACKGROUND: Solitary fibrous tumors (SFT) arising from the larynx are extremely rare; most occur in the supraglottic larynx. CASE REPORT: Herein, we detail a new case of a subglottic SFT presenting as a well-encapsulated soft-tissue tumor with hoarseness. It showed isoattenuation, similar to the adjacent muscle on pre-contrast computed tomography (CT) images, and strong, heterogeneous enhancement following contrast material administration, which may reflect hypervascularity...

The rare and potentially fatal complication of asystole during direct laryngoscopy is linked to direct vagal stimulation. This case describes asystole in an 85-year-old female who underwent suspension microlaryngoscopy with tracheal dilation for subglottic stenosis. Quick recognition of this rare event with immediate cessation of laryngoscopy resulted in the return of normal sinus rhythm. This incident emphasizes the implications of continued vigilance during laryngoscopy and the importance of communication between the anesthesia and surgical staff to identify and treat this rare complication...

OBJECTIVE: To identify a safe approach to airway management during the endoscopic balloon dilation of subglottic stenosis BACKGROUND: Subglottic stenosis is an abnormal narrowing of the upper airway commonly managed by endoscopic technique performed on an unsecured airway. METHODS: Review of surgical treatment of subglottic stenosis cases by the senior author. TECHNIQUE: Following steroid injection and radial cuts performed either under jet anesthesia or mask ventilation with brief periods of apnea, a small endotracheal tube may be passed beyond the narrowing to permit adjacent balloon dilation with the airway secured...

BACKGROUND: Ventilator-associated pneumonia (VAP) is one of the most common and preventable infections in mechanically ventilated patients. It is associated with a high mortality rate. To prevent VAP, various strategies address this issue using "VAP-bundles", which are implemented in many intensive care units. The risk of acquiring VAP starts with the induction of anesthesia, strictly speaking at the time of intubation. This article considers measures to prevent VAP during general anesthesia in adult patients (>18 years)...

A 23-day-old infant referred to the neonatal intensive care unit with difficulty breathing and inspiratory stridor increasing with exercise. Medical history included a cardiothoracic surgery for transposition of the great arteries, patent ductus arteriosus, atrial septal defect, and a history of intensive care unit from surgery. Flexible fiberoptic transnasal laryngoscopy revealed subglottic stenosis that was probably caused by prolonged intubation with a higher airway pressure. Computed tomographic scan of the neck showed a tiny stenosis without cartilage deformity and limited in subglottic region...
