Brief summary

The primary outcome of the study is the first-attempt orotracheal intubation success rate and the secondary outcomes include intubation time, mucosal injury, and complications during intubation.

Detailed description

Difficult airway management in phonomicrosurgery requiring endotracheal tube (ETT) placement is highly important for both the anesthetist and the surgeon. The use of rigid telescopes in the intubation of children with difficult intubation, such as those with Pierre Robin sequence (PRS), has been previously described in the literature. In addition, the use of Airtraq™ and rigid endoscopes in patients undergoing phonomicrosurgery, particularly in patients with difficult laryngoscopy, has also been reported in the literature. However, the uses of these techniques have mostly been described in the administration of surgery or in defining airway disease. In this study, we aimed to evaluate the use of rigid telescopes during intubation, particularly in patients with a difficult airway, and to compare them with videolaryngoscope Macintosh (V-MAC) and flexible fiberoptic bronchoscope.
