Background: Modified Mallampati test is a standard method of assessing the airway for predicting potentially difficult laryngoscopy and intubation. This test requires the patient to be in sitting position for airway evaluation. Although applicable to the majority of patients, airway evaluation in sitting position may not always be convenient or advisable. Objectives: To compare modified Mallamp...

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...

Using readily available and objective airway risk criteria, a multivariate model for stratifying risk of difficult endotracheal intubation was developed and its accuracy compared to currently applied clinical methods. We studied 10,507 consecutive patients who were prospectively assessed prior to general anesthesia with respect to mouth opening, thyromental distance, oropharyngeal (Mallampati) ...

BACKGROUND AND OBJECTIVE The Intubating Laryngeal Mask Airway FastrachTM (ILMA) has been used with success in difficult intubation cases. The purpose of this study is to evaluate the effect of mouth opening, Mallampati classification, thyromental distance and Cormack-Lehane Grade, on the ease of ILMA use. METHODS Eighty one patients ASA I-II, were assessed preoperatively for mouth opening, Ma...

INTRODUCTION The success of pharyngeal surgery in the treatment of obstructive sleep apnea syndrome depends on the appropriate selection of patients. OBJECTIVE To propose a new staging for indication of pharyngeal surgery in obstructive sleep apnea syndrome. METHODS A total of 54 patients undergoing extended tonsillectomy were retrospectively included, divided into six stages. Stage I: pati...

OBJECTIVES/HYPOTHESIS To determine whether Mallampati class correlates with Cormack-Lehane grade in obese adults, and investigate a novel airway trajectory measurement (ATM) to anticipate difficult laryngoscopy. STUDY DESIGN Retrospective cohort plus a pilot study. METHODS One hundred eighty-four nonobese and 160 obese adults underwent laryngoscopy. Spearman correlations, gamma coefficients...

Preoperative airway assessment for prediction of difficult laryngoscopy and intubation was done using the modified Mallampati test and Wilson risk sum score in three hundred and seventy two obstetric patients undergoing elective as well as emergency Cesarean section under general anesthesia. 25 (6.7%) patients had laryngoscopy grade III or IV of whom 24 (6.4%) patients were difficult at trachea...

BACKGROUND AND OBJECTIVE Prediction of intubation difficulty can save patients from major preoperative morbidity or mortality. The purpose of this paper is to assess the correlation between oro-hypo pharynx position, neck size, and length with endotracheal intubation difficulty. The study also explored the diagnostic value of Friedman Staging System in prediction cases with difficult intubation...
