Which Mallampati class is characterized by only visualizing the base of the uvula?

The Mallampati classification system is used to predict the ease of intubation based on the visibility of oral structures. In this system, different classes represent varying degrees of visibility of the oropharyngeal structures when a patient opens their mouth and sticks out their tongue.

Mallampati class III is specifically characterized by the observation of only the base of the uvula. In this class, the tonsils and soft palate are typically not visible, indicating a more challenging intubation scenario compared to the earlier classes where more structures are observed. This reduced visibility can be an important factor in planning for airway management during surgical procedures.

Understanding the implications of each Mallampati class is crucial for oral and maxillofacial surgery assistants, as it helps them prepare for potential challenges during anesthesia and intubation.
