“…[17][18][19] ), there was agreement between the assessors in 91% cases (κ=0.370, AC1=0.897). Similarly, in the parameter TM joint movement, the inter-observer agreement was in 83% cases (κ=0.088, AC1=0.797).…”

“…To reduce this potential source of error, we used both written description of all measurements and practical training of the assessors before the start of the study. However, it is doubtful whether these steps were 14,15 , n/A = not applicable DI = difficult intubation, MMT = Modified Mallampati test 16 , ULBT = Upper lip bite test [17][18][19] , TM = temporo-mandibular Inter-observer agreement 8 When necessary, the required maneuvers were clearly described several times and demonstrated repeatedly 11 . This study is relevant not only to pre-anesthetic airway assessment and predicting DI.…”

“…In our study, MMT (Modified Mallampati test) (ref. 16 ), ULBT (Upper lip bite test) [17][18][19] and Temporo-mandibular (TM) joint movement were the relevant parameters suitable for merging groups. In three volunteers, clinical impression of potential DI was positive (one in the O group, two in the T group).…”

Aim.To determine the inter-observer reproducibility of 15 tests used for predicting difficult tracheal intubation (DI). Material and methods. Following local ethics committee approval and informed consent, 101 volunteers were examined by two assessors using 15 tests for predicting DI. The two assessors who were blinded to the results of the other, examined each volunteer independently. Cohen's kappa (κ) or first-order agreement coefficient (AC1) were used to measure agreement between assessor ratings on a qualitative scale. Agreement between two quantitative outcomes was described using the intraclass correlation coefficient ( Conclusion. Best inter-rater agreement was found for the assessment of neck circumference while the highest discrepancies between raters were in goniometrically-measured mobility of the C-spine.Many of the pre-operative airway tests had only fair inter-observer reproducibility. This may be one reason why models for predicting difficult intubation are not universally reliable.

“…Effective and reliable prediction requires a com-Mallampati test as a predictor of laryngoscopic view bination of several parameters (e.g. age, height, weight, BMI, MMT, head and neck movement, dentition status, upper lip bite test [18][19][20] , interincisor gap 17,21,22 , and thyromental distance 17,22,23 ). Usually, the more parameters are used, the higher is the accuracy of prediction.…”

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.

BackgroundThe unanticipated di icult airway is a potentially life-threatening event during anaesthesia or acute conditions. An unsuccessfully managed upper airway is associated with serious morbidity and mortality. Several bedside screening tests are used in clinical practice to identify those at high risk of di icult airway. Their accuracy and benefit however, remains unclear. ObjectivesThe objective of this review was to characterize and compare the diagnostic accuracy of the Mallampati classification and other commonly used airway examination tests for assessing the physical status of the airway in adult patients with no apparent anatomical airway abnormalities. We performed this individually for each of the four descriptors of the di icult airway: di icult face mask ventilation, di icult laryngoscopy, di icult tracheal intubation, and failed intubation. Search methodsWe searched major electronic databases including CENTRAL, MEDLINE, Embase, ISI Web of Science, CINAHL, as well as regional, subject specific, and dissertation and theses databases from inception to 16 December 2016, without language restrictions. In addition, we searched the Science Citation Index and checked the references of all the relevant studies. We also handsearched selected journals, conference proceedings, and relevant guidelines. We updated this search in March 2018, but we have not yet incorporated these results. Selection criteriaWe considered full-text diagnostic test accuracy studies of any individual index test, or a combination of tests, against a reference standard. Participants were adults without obvious airway abnormalities, who were having laryngoscopy performed with a standard laryngoscope and the trachea intubated with a standard tracheal tube. Index tests included the Mallampati test, modified Mallampati test, Wilson risk score, thyromental distance, sternomental distance, mouth opening test, upper lip bite test, or any combination of these. The target condition was di icult airway, with one of the following reference standards: di icult face mask ventilation, di icult laryngoscopy, di icult tracheal intubation, and failed intubation. Airway physical examination tests for detection of di icult airway management in apparently normal adult patients (Review)
