Brief Summary
Anesthesia is increasingly safe. Major complications of airway management are no more common but still the most life-threatening condition amongst anesthesia practice and even medicine. Thyromental height test (TMHT) is an objective measure of the height between the anterior borders of the mentum and thyroid cartilage, measured while the patient is lying supine with the mouth closed. This study was designed to assess the validity of the TMHT as a single objective predictor for difficult laryngoscopy and to be compared to other objective measures.

Outcome Measures
Primary Outcomes (2)
validity of the TMHT in prediction of difficult airway in patients undergoing general anesthesia for elective surgeries using area under ROC curve for the TMHT.
baseline (before induction of general anesthesia)
Validity of TMHT in comparison with that of Modified Mallampati test (MMT) in prediction of difficult airway by comparing area under ROC curve for both tests.
baseline (before induction of general anesthesia)

Assessment of difficult airway
Eligibility Criteria
Patients, aged from 18-60 years old, with ASA physical status I \& II who will undergo elective surgical procedures under general anesthesia using endotracheal intubation using conventional laryngoscopy.
You may qualify if:
- ASA physical status I \& II
- Scheduled for elective surgical procedures under general anesthesia using endotracheal with conventional laryngoscopy
You may not qualify if:
- Patients with a body mass index \>35 kg/m2.
- Patients with neuromuscular disorders, craniofacial abnormalities, and abnormal dentition.
- Patients with airway diseases e.g cancer larynx or tongue, uncooperative patients, those who will need awake intubation and patients who will undergo emergency operations.
