Mallampati classification

(ma-lam-pot′ē)
A four-point scale used to assess the relative ease of oral (endotracheal) intubation of a patient based on the size and position of the tongue relative to the size of the pharyngeal opening. The patient should be assessed in the sitting position, with the neck in neutral position, the mouth maximally opened, and the tongue protruded as far as possible. The four classifications of the scale are: 1.full visibility of the soft palate, uvula, tonsillar pillars, and fauces; 2.visibility of the soft palate and part of the pendant uvula; 3.visibility of the soft palate and only the base of the uvula; and 4.visibility of only the hard palate.

Inclusion criteria were as follows: (1) patients with oral, upper airway and tracheal tumors or neoplasms; (2) patients with tracheal compression by cervical neoplasms or masses; (3) patients with tracheal deviation or stenosis caused by neck trauma, burns, surgical procedures, and radiotherapy; (4) patients with body mass index (BMI) ≥30, Mallampati score III-IV and thyromental distance <6.
2) reported a poor-to-moderate sensitivity for all these tests and indicated that a combination of thyromental distance and Mallampati score has the highest predictive value.
He had no facial abnormalities, and his Mallampati score was class II.

Mallampati score (visibility of the soft palate, uvula, and faucial pillars when the patient is asked to open his mouth and protrude his tongue as much as possible).
The physical exam revealed central cyanosis and blood pressure of 140/80 mmHg, heart rate of 68bpm, respiratory rate of 19 breaths/min, Mallampati score of II, oral aperture above 4 cm, cervical perimeter below 40 cm, 35[degrees] extension of the upper neck and thyromental distance above 6 cm.
He reported a Mallampati score of 4, which indicates that the soft palate and tongue have visually obstructed the airway when the patient is sitting in an upright position (Figure 1).
This is because the patient is required to open the mouth and put the tongue out simultaneously for Mallampati score evaluation.

Preoperative airway assessment revealed limited neck extension, mouth opening for 1 cm, old scars on the cheek and neck, a thyromental distance of 3 cm, and a modified Mallampati score of Class IV.
