During the Mendelsohn maneuver, how long should the larynx be held at maximal elevation after the height of swallow?

• A. 0.5 seconds
• B. 1-2 seconds
• C. 5-6 seconds
• D. 10 seconds

Answer: (B)

The Mendelsohn maneuver works by prolonging the position of laryngeal elevation so the cricopharyngeal sphincter (UES) stays open longer and pharyngeal clearance improves. After you reach the peak height of elevation, holding the larynx in that position for about 1–2 seconds gives enough time for the UES to remain open and for the swallow to proceed more effectively, reducing residue and aiding safe passage of the bolus. Holding for only a brief moment (like 0.5 seconds) may not provide enough delay to maximize the opening, while holding much longer (5–10 seconds) can cause unnecessary fatigue without additional benefit.
