Airway management is a critical skill in the practice of several medical specialities including anesthesia, emergency medicine, and critical care. Over the years mounting evidence has showed an increasing role of ultrasound (US) in airway management. The objective of this narrative review is to provide an overview of the indications for point-of-care ultrasound (POCUS) of the upper airway. The use of US to guide and assist clinical airway management has potential benefits for both provider and patient. Ultrasound can be utilized to determine airway size and predict the appropriate diameter of single-lumen endotracheal tubes (ETTs), double-lumen ETTs, and tracheostomy tubes...

Endogenous stem cells are indispensable to keep tissue homeostasis due to their unique ability to generate more specialized cell types in an organized way depending on the body needs. Precise control over stem cell differentiation is essential for organogenesis and tissue homeostasis. Stem cells reside in specialized microenvironments, also called niches, which maintain them in an undifferentiated and self-renewing state. The cellular and molecular mechanisms of stem cell maintenance are key to the regulation of homeostasis and likely contribute to several disorders when altered during adulthood...

OBJECTIVES: Neonatal intubation is a difficult skill to learn and teach. If an attempt is unsuccessful, the intubator and instructor often cannot explain why. This study aims to review videolaryngoscopy recordings of unsuccessful intubations and explain the reasons why attempts were not successful. STUDY DESIGN: This is a descriptive study examining videolaryngoscopy recordings obtained from a randomised controlled trial that evaluated if neonatal intubation success rates of inexperienced trainees were superior if they used a videolaryngoscope compared with a laryngoscope...

BACKGROUND: When intubating newborns, clinicians aim to position the endotracheal tube (ETT) tip in the midtrachea. The depth to which ETTs should be inserted is often estimated using the infant's weight. ETTs are frequently incorrectly positioned in newborns, most often inserted too far. Using the vocal cord guide (a mark at the distal end of the ETT) to guide insertion depth has been recommended. OBJECTIVE: To determine whether estimating ETT insertion depth using the vocal cord guide rather than weight results in more correctly positioned ETT tips...

BACKGROUND: Adenoid cystic carcinoma (ACC) of the larynx and trachea is very rare. CASE: A 45-year-old man with ACC of the larynx presenting as a thyroid mass is reported in this study. Physical examination revealed a large solid thyroid nodule in the left lobe without any lymphadenopathy. A technetium thyroid scan showed multinodular goiter with cold nodules in the left lobe, isthmus, and functioning nodules in the right lobe. A large thyroid mass originating from the left side of the larynx, mostly the left vocal cord and the infraglottic part, was seen using enhanced magnetic resonance imaging after rupture of the thyroid cartilage on the left side...

Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma...

INTRODUCTION: In the difficult airway, the intubation skills are critically important. In selected cases, particularly in airway edema, laryngeal or tongue edema, endotracheal intubation can turn out very difficult, and repeated attempts may even worsen the airway edema, causing trauma and bleeding, and finally leading to complete airway obstruction and inability to ventilate the patient. AIM OF THE STUDY: The aim of the study was to compare the efficacy of endotracheal intubation performed by novice physicians using a standard Macintosh laryngoscope and an Intubrite videolaryngoscope...

Retrograde intubation is an invaluable technique which can be helpful in anticipated difficult airway situation. In this advanced era where fiberoptic intubation and video laryngoscopes are in abundant use, retrograde intubation is a forgotten technique. However, it may be useful in various difficult airway situations in this advanced era. In our case the patient had a bitter experience with previous fiberoptic intubation. Owing to that we had planned and performed a fiber optic guided retrograde intubation, where we had kept the fiberoptic bronchoscope in the pharynx keeping larynx and vocal cords in the focus to facilitate the emergence of guide wire through one of the nostrils as well as direct visual confirmation of intubation...

BACKGROUND: Systematic reviews comparing treatment of early glottic cancer with transoral surgery or radiotherapy demonstrate similar oncological outcomes. Most studies of 'early-stage' laryngeal cancer include Tis, T1a, T1b and T2 cases. The data are dominated by patients with T1 and Tis tumours, although extrapolating these results and applying them for T2 cases may be inappropriate. No previous systematic reviews have focused on T2 cancers as a separate group. OBJECTIVE OF REVIEW: This review compares local control outcomes for T2 glottic squamous cell carcinoma, treated with transoral microsurgery or external beam radiotherapy...

Nonrecurrent laryngeal nerve (non-RLN) is an anatomical variation increasing the risk of vocal cord palsy. Prediction and early identification of non-RLN may minimize such a risk of injury. This study assessed the effect of intraoperative neuromonitoring (IONM) on the detection of non-RLN. A total of 462 (236 right) nerves in 272 patients were identified and totally exposed, and all intraoperative steps of IONM were sequentially applied on the vagus nerve (VN) and RLN. Right predissection VN stimulation at a distal point did not create a sound signal in three cases (3/236; 1...
