Abstract Background Routine preoperative methods to assess airway such as the interincisor distance (IID), Mallampati classification, and upper lip bite test (ULBT) have a certain risk of respiratory tract exposure virus spread. Condyle-tragus maximal distance(C-TMD) can be used airway, does not require patient expose tract, but its value in predicting difficult laryngoscopy compared other indi...

UNLABELLED The aim of the study was to determine the predicting tests for difficult airway and difficult intubation in apparently normal patients. METHODS We were using the literature about the specific tests for predicting difficult airway and single parameters that could be a significant test for prediction of difficult or impossible intubation. Clinical risk factors for difficult intubatio...

BACKGROUND Failure to maintain an adequate airway can lead to brain damage and death. To reduce the risk of difficulty in maintaining an airway during general anesthesia, there are several known predictors of difficult intubation. People with a Malay background have different craniofacial structures in comparison with other individuals. Therefore, different predictors should be used for patient...

BACKGROUND Preoperative evaluation of anatomical landmarks and clinical factors are important in the detection of patients at risk for difficult laryngoscopy. The modified Mallampati test (MMT) and thyromental distance (TMD) are commonly used for this purpose but there are controversies regarding their accuracy. OBJECTIVE The objective of the present study was to evaluate the accuracy of MMT ...

Morbid obesity is associated with difficult laryngoscopy and intubation. In the general population, bedside indices for predicting difficult intubation (i.e. Mallampati classification, thyromental distance, sternomental distance, mouth-opening and Wilson risk score) have poor-to-moderate sensitivity (20-62%) and moderate-to-fair specificity (82-97%). In the obese population, although the risk o...

OBJECTIVE To determine the accuracy of the Upper lip bite test and Mallampati test in predicting difficult endotracheal intubation. METHODS The cross-sectional study was conducted at the Aga Khan University Hospital, a tertiary care facility in Karachi, Pakistan. Between June 1,2007 and May 31, 2008, 324 adult patients undergoing elective surgeries requiring general anaesthesia with endotrach...

BACKGROUND We studied the differences in airway assessment factors among old, middle, and young age groups, and evaluated the frequency and causes of difficult intubation among these groups. METHODS Patients were divided into young (< 40 yr, n = 75 ), middle (40-59 yr, n = 83), and old (≥ 60 yr, n = 89) group. Airway assessment factors such as head and neck movement, thyromental distance, int...

The four-point modified Mallampati (MMP) score is widely used as a marker of difficult intubation. The evaluation is usually performed by having patients open their mouth and protrude their tongue with the head and neck in a neutral position. However, mouth opening has been shown to be greater when the head and neck are extended. In this study, examiners with a minimum of 1 year of airway exper...
