“…THAM et al [20] observed that posture had a very small effect on the MS in a group of 128 subjects. Supine position displaced the distribution of the MS slightly towards the higher classes of Mallampati.…”

Induced nasal obstruction can cause obstructive apnoeas in healthy subjects during sleep, but the relationship between nasal resistance measured during wakefulness and obstructive sleep apnoea syndrome (OSAS) is weak. It was postulated that if the subjects could not breathe through the nose, the oral airway must be used, but if this airway is narrowed as well, then it could precipitate sleep-disordered breathing (SDB).Nasal patency, Mallampati score (MS), neck circumference and body mass index were measured in 202 subjects referred to the authors9 hospital to undergo a full-night polysomnography for suspicion of SDB.A significant correlation was found between the MS and apnoea/hypopnoea index measured during sleep. However, the relationship between these parameters was only significant in patients with nasal obstruction. The relative risk of having OSAS with a MS of III or IV was 1.95 for the whole group and 2.45 in patients with nasal obstruction.In conclusion, a high Mallampati score represents a predisposing factor for obstructive sleep apnoea syndrome, especially if it is associated with nasal obstruction. These patients merit special attention from both the sleep physician and the anaesthetist.

“…The classical Mallampati test is done in the sitting patient, with his/her head in the neutral position. However, when performed in the supine position, the test may have a higher positive predictive value and is associated with more true positives than assessment in the sitting position [10][11][12] . The specificity and positive predictive value of the MMT can be improved when performed in the sitting patient with extension of the craniocervical junction 13 .…”

Aim.To determine the accuracy of the modified Mallampati test for predicting difficult tracheal intubation. Design. A cross-sectional, clinical, observational, non-blinded study. A quality analysis of anesthetic care. Setting. Operating theatres and department of anesthesiology in a university hospital. Material and methods. Following the local ethics committee approval and patients' informed consent to anesthesia, all adult patients (> 18 yrs) presenting for any type of non-emergency surgical procedures under general anesthesia requiring endotracheal intubation were enrolled. Prior to anesthesia, Samsoon and Young's modification of the Mallampati test (modified Mallampati test) was performed. Following induction, the anesthesiologist described the laryngoscopic view using the Cormack-Lehane scale. Classes 3 or 4 of the modified Mallampati test were considered a predictor of difficult intubation. Grades 3 or 4 of the Cormack-Lehane classification of the laryngoscopic view were defined as impaired glottic exposure. The sensitivity, specificity, positive and negative predictive value, relative risk, likelihood ratio and accuracy of the modified Mallampati test were calculated on 2x2 contingency tables.Results. Of the total 1,518 patients enrolled, 48 had difficult intubation (3.2%). We failed to detect as many as 35.4% patients in whom glottis exposure during direct laryngoscopy was inadequate (sensitivity 0.646). Conclusion. When used as a single examination, the modified Mallampati test is of limited value in predicting difficult intubation.

“…Eighteen (36%) patients in Gr-A faced difficulties during intubation, which is significantly higher than the Gr-B (p =0.001). 10 . One of the greatest criticisms of mallampati test, however, has been the problem of inter-observer variation 9 .…”

In this prospective study, one hundred adult patients, fifty in each group were assessed before operation, using the modified mallampati test in Group-A and mallampati & measurement of Thyromental Distance (TMD) in Group-B. The groups were matched for age (P=0.539), Sex (P=0.688), weight (P=0.077), and ASA physical status (P=0.436). Total number of patients facing difficulties during intubation are significantly higher in the Group-A (18 in Group-A and 10 in Group-B) (p =0.001). The measured sensitivity and specificity in Group-A are 65% and 25% respectively. On the other hand, the sensitivity, specificity in Group-B are 75% & 60%. So, the combination of Thyromental Distance and Mallampati test may be done as screening test during preoperative visit which may present fatal consequences of difficult and or failed intubation.
