REVIEW

The C-MAC videolaryngoscope is the first Macintosh-typed videolaryngoscope. Since the advent of its original version video Macintosh system in 1999, this device has been modified several times. A unique feature of C-MAC device is its ability to provide the 2 options of direct and video laryngoscopy with the same device. The available evidence shows that in patients with normal airways, C-MAC videolaryngoscope compared with direct laryngoscopy can provide comparable or better laryngeal views and exerts less force on maxillary incisors, but does not offer conclusive benefits with regard to intubation time, intubation success, number of intubation attempts, the use of adjuncts, and hemodynamic responses to intubation...

A 43-year-old man with complaints of increased difficulty of swallowing and weight loss underwent videofluorographic examination of swallowing, which revealed severely reduced cricopharyngeal opening. Endoscopic cricopharyngeal myotomy was performed using a modified technique (mECPM). A benign fibrotic stricture of the upper esophageal sphincter (UES) was identified under visualization of a distending operating laryngoscope. A vertical midline incision in the strictured mucosa and submucosal resection of the cricopharyngeal muscle were performed using a CO2 laser...

Congenital vallecular cyst is a rare laryngeal lesion, accounting for 10-20% of all laryngeal cysts, with a potential to cause severe upper airway obstruction, which can be fatal. It can cause stridor, apnea, cyanosis, respiratory distress, and feeding difficulties. Diagnosis requires a high level of clinical suspicion and helps in timely intervention. Direct laryngoscopy is gold standard for definitive diagnosis. Treatment options include aspiration, marsupialization, and surgical excision. Here, we report a case of 7-week-old infant with complain of recurrent episodes of cyanosis when agitated, since the age of 3 weeks, admitted with impression of apparent life-threatening events (ALTEs)...

Unexplained dysphagia requires prompt investigation to rule out a possible underlying malignancy. We describe the case of a 60-year-old man who presented to his family practitioner with a 1-year history of increasing dysphagia with associated pain over the front of his chest. He was referred on to an ear, nose and throat specialist where no obvious laryngeal pathology was found at direct laryngoscopy, but an 'indentation' of the right anterior larynx, which increased with external pressure on the sternoclavicular joint (SCJ), was noted...

The laryngoscope should displace oral soft tissues forward out of the operator's vision. Therefore, the space in front of the view may be critical for determining the laryngoscopic view. The aim was to investigate the difference in the previsional space during difficult versus easy laryngoscopy (EL).Under general anesthesia, digital photographs of the lateral view of the head and neck were taken in the horizontal sniffing position, after head extension, and during laryngoscopy with a defined force (50 N)...

OBJECTIVE: Patients with pulmonary hypertension and right heart failure have a high risk of clinical deterioration and death during or soon after endotracheal intubation. The effects of sedation, hypoxia, hypoventilation, and changes in intrathoracic pressure can lead to severe hemodynamic instability. In search for safer approach to endotracheal intubation in this cohort of patients, we evaluate the safety and feasibility of an alternative intubation technique. DATA SOURCES: Retrospective data analysis...

BACKGROUND AND OBJECTIVES: The laryngeal mask airway (LMA) ProSeal is most commonly used supraglottic airway device; it is routinely inserted by blind technique. Although blind insertion technique is most widely used, there are many techniques which are available such as priming the drain tube with a guiding instrument such as a suction catheter, a gum elastic bougie, a Flexi-Slip Stylet, direct laryngoscopy, and even a fiber-optic bronchoscope (FOB). The present study was undertaken to compare and assess the placement of LMA ProSeal using blind versus direct laryngoscopy techniques using FOB...

In paediatric patients, airway management can be challenging due to unique anatomical and physiological variations. Hence, a thorough history, examination and pre-operative planning are essential in securing difficult airway in paediatrics. We report a case of a 7-month-old infant with rhabdomyosarcoma of the upper lip with anticipated difficult airway. The airway was managed with three different conventional techniques (modified nasal trumpet, supraglottic airway and direct laryngoscopy) for three different procedures in the same infant...

A 23-year-old woman presented to the emergency department (ED) with a sensation of a 'fish bone' stuck in her throat after eating cod. On physical examination, while she reported an uncomfortable sensation in her throat, no airway compromise was evident. Clinical examination, including ear, nose and throat (ENT) and oropharyngeal assessment, was unremarkable. A linear opacity consistent with a fishbone was visualised on a soft tissue lateral neck X-ray anterior to the vertebral body of C4-6. One attempt to visualise the fishbone on direct laryngoscopy failed in the ED...
