Within the LEMON mnemonic for predicting difficult laryngoscopy, which step specifically focuses on external examination for airway distortions?

• A. L-look externally for anatomical distortions
• B. E-evaluate 3-3-2 rule
• C. M-mallampati
• D. N-neck mobility

Answer: (A)

The step being tested is looking externally for airway distortions. This part of the assessment involves visually inspecting the face and neck for any abnormalities that could distort airway anatomy or complicate intubation—such as trauma, tumors, edema, congenital deformities, or significant dental issues. Detecting these distortions early helps you predict a difficult laryngoscopy and plan accordingly, perhaps by using alternative airway devices or considering awake techniques if needed. The other steps focus on different factors: the space available for the laryngoscope and tube (3-3-2 rule), visibility of oropharyngeal structures (Mallampati), and how well the neck can extend (neck mobility).
