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.
I and II as per airway assessment.
He had no facial abnormalities, and his Mallampati score
was class II.
Nasal obstruction and High Mallampati Score
as Risk Factors for Obstructuve Sleep Apnea.
(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
Physical Examination: Mallampati Score
as an Independent Predictor of Obstructive Sleep Apnea.
12 The increase in Mallampati score
correlates with gain in body weight.
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.
