Cysts of epiglottis are rare. Following induction of anesthesia, asymptomatic cysts may lead to unanticipated difficulty in ventilation or intubation or both and can be potentially life threatening in such situations.

71 years ago, the most popular curved laryngoscope in the world the Macintosh laryngoscope was designed by Sir Robert Reynolds Macintosh, which was expected to expose the larynx more easily under lighter anesthesia than that with the straight laryngoscope by elevating the epiglottis indirectly [1]. Although the design process of the Macintosh laryngoscope was mentioned in 1944, detailed feature...

The measurement system for the pressure between the blade of a laryngoscope and the upper airway tract during orotracheal intubation has been investigated with a film of microcapsules. Two types of the laryngoscope were used in the study: WisForegger and Mac-Intosh. The film is attached on the surface of the blade of the laryngoscope. The measurement was applied to 20 cases of the orotracheal i...

Laryngomalacia is the most common cause of stridor in neonates and infants, where the soft cartilages and tissues surrounding the upper larynx collapse inward during respiration. On the other hand, acquired idiopathic laryngomalacia in adults is quite rare, but should be borne in mind for differential diagnosis of upper airway distress. Allergic factors may cause airway distress, but have not b...

grille, larynx seen by manipulation of the fibrescope; grade 4, epiglottis down-folded, larynx not seen. The results are shown in the Table. In five of the seven patients, the LMA provided an acceptable patent airway. In the remaining two patients (cases three and six), however, down-folding of the epiglottis caused severe airway obstruction. In case three, establishment of a patent airway via ...
