Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult patients over 18 years old undergoing elective maxillomandibular fixation surgeries under general anesthesia.
✕Probably not a fit
Patients with certain medical conditions, such as neuromuscular diseases or uncontrolled diabetes, or those who have had recent upper airway infections may not benefit from this study.

What this trial studies
This study aims to identify patients at risk of developing post-extubation stridor, a condition characterized by noisy breathing due to airway narrowing after surgery. It utilizes ultrasound to measure laryngeal morphology and assess the laryngeal air-column width, which can help predict the likelihood of stridor. Additionally, the cuff-leak test will be employed to evaluate the risk of stridor based on the difference in tidal volume with the cuff inflated versus deflated. The goal is to enhance patient safety during recovery from maxillomandibular fixation surgeries.
Why it matters
Potential benefit: If successful, this study could lead to improved prediction and management of post-extubation stridor, enhancing patient safety and recovery outcomes.
How similar studies have gone: While the use of ultrasound for laryngeal assessment is established, the specific predictive approach in this study is novel and has not been extensively tested in similar contexts.
