What is the modified Mueller technique primarily used to evaluate?

The modified Mueller technique is primarily used to evaluate obstructive sleep apnea. This diagnostic method involves having the patient perform a series of maneuvers while being observed and monitored, which allows for the assessment of airway collapsibility during inspiration. The technique measures the response of the upper airway to negative pressure, simulating conditions that may lead to obstruction during sleep.

In the context of obstructive sleep apnea, this procedure is essential as it helps to identify sites of obstruction and the severity of airway collapse. Understanding the dynamics of airway patency under varying pressures is crucial for diagnosing this condition effectively and tailoring appropriate treatment strategies, such as CPAP therapy or surgical interventions. This evaluation is particularly valuable as it contributes to a comprehensive understanding of the mechanisms behind sleep-disordered breathing.
