Here is a complete explanation of the Mallampati Classification:
Mallampati Classification
Background
Introduced by Seshagiri Rao Mallampati in 1985 (Can Anaesth Soc J. 1985;32:429-434), this is a bedside clinical test used to predict the ease of tracheal intubation by assessing the oropharyngeal view. It was later modified by Samsoon and Young (1987) to include the current 4-class system.
How to Perform the Test
- Patient sits upright, head in neutral position
- Mouth opened maximally
- Tongue protruded fully - without phonation
- Examiner inspects the oropharynx at eye level
- Classify based on visible structures
The 4 Classes (Modified Mallampati)
| Class | Structures Visible | Laryngoscopy | Intubation Difficulty |
|---|---|---|---|
| Class I | Soft palate, uvula, fauces, tonsillar pillars | Cormack-Lehane Grade 1 | Easy |
| Class II | Soft palate, uvula, fauces (pillars NOT seen) | CL Grade 1-2 | Relatively easy |
| Class III | Soft palate + base of uvula only | CL Grade 2-3 | Potentially difficult |
| Class IV | Hard palate only - nothing else visible | CL Grade 3-4 | Very difficult |
Class I and II = low risk of difficult intubation Class III and IV = high risk - prepare for difficult airway management
Correlation with Cormack-Lehane Grade
The Cormack-Lehane (CL) grading classifies the laryngoscopic view:
| CL Grade | View at Laryngoscopy |
|---|---|
| Grade I | Full glottis visible |
| Grade II | Partial glottis / arytenoids visible |
| Grade III | Epiglottis only visible |
| Grade IV | Epiglottis not visible |
Higher Mallampati class correlates with higher CL grade, and therefore greater difficulty with intubation.
Clinical Significance
- Sensitivity: ~50-60% for predicting difficult laryngoscopy (moderate - no single test is perfect)
- Specificity: ~85-90%
- Best used in combination with other tests - not as a standalone predictor
- Predictive value improves when combined with: thyromental distance, sternomental distance, interincisor gap, neck mobility, and body weight
- Models like the El-Ganzouri risk index and Wilson risk sum score combine Mallampati with other factors for better prediction
Combined Airway Assessment - The LEMON Rule
| Letter | Parameter |
|---|---|
| L | Look externally - obesity, beard, edentulous, trauma |
| E | Evaluate 3-3-2 rule (inter-incisor ≥3 fingers, hyoid-chin ≥3 fingers, thyroid-mouth floor ≥2 fingers) |
| M | Mallampati score (Class III or IV = concern) |
| O | Obstruction / OSA |
| N | Neck mobility (limited = risk) |
Other Associated Predictors of Difficult Airway
| Parameter | Concerning Value |
|---|---|
| Thyromental distance | < 6 cm (< 3 finger breadths) |
| Mouth opening (inter-incisor gap) | < 3 cm |
| Neck extension | < 80° |
| Upper lip bite test (ULBT) | Cannot bite upper lip |
| Sternomental distance | < 12.5 cm |
| BMI | > 35 (especially with OSA) |
Additional Uses Beyond Intubation
- Obstructive Sleep Apnea (OSA) prediction: Class III/IV suggests crowded oropharynx - tissue more likely to collapse during sleep. Combined with STOP-BANG score for OSA screening.
- LMA placement: Higher classes may predict difficult LMA seating
- Regional anaesthesia planning: Backup airway planning if regional fails
Limitations
Per Miller's Anesthesia 10e:
- Individual airway tests including Mallampati have low sensitivity and positive predictive value when used alone
- Interobserver variability exists - scoring can differ between examiners
- The Upper Lip Bite Test (ULBT) has been shown to predict difficult laryngoscopy with higher specificity and less interobserver variability
- Point-of-care ultrasound and computer-assisted models (using BMI + mouth opening + thyromental distance + Mallampati + receding mandible together) are showing better predictive accuracy in newer studies
- A negative (reassuring) Mallampati score does not exclude difficult intubation - always be prepared

Both files exist and are valid. The issue is likely on the browser/interface side. Let me try a few things:
1. Try the PDF instead - it's often easier to open directly in browser:
Preanaesthetic Check Up
PDF Document · PDF
2. Try right-clicking the link and selecting "Save link as..." or "Download linked file"
3. If on mobile - try opening in a desktop browser instead
4. Check your browser's download folder - it may have downloaded silently without a prompt
If none of those work, here are some troubleshooting tips:
| Issue | Solution |
|---|---|
| Link opens blank page | Right-click → Save As |
| "File not found" error | Refresh the page and try again |
| Download blocked | Check browser download settings / allow pop-ups |
| On mobile | Switch to desktop mode in browser settings |
| Still failing | Let me know your browser/device and I'll suggest alternatives |
The PDF version (267 KB) is a great alternative if the PPTX continues to be problematic - it contains all 22 slides with full formatting and is viewable on any device without PowerPoint installed.
