THE Mallampati classification is a rough estimate of the tongue size relative to the oral cavity. Although the single usage of the Mallampati classification has limited discriminative power for difficult tracheal intubation, it is a simple, reproducible, and reliable preanesthetic airway assessment method when performed properly. In addition to difficult tracheal intubation, Mallampati class 3 ...

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...

Background: The responsibility of the anesthesiologist is to maintain airway patency for better oxygenation. Perhaps the most dangerous incident for the anesthesiologist, are encountering the scenario in which intubation and ventilation in a patient are impossible. The study of mask ventilation is far more limited. The first significant manuscript focused on mask ventilation was published in 20...

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 We evaluated the effects of conventional tracheal tube orientation on success of intubation through an intubating laryngeal mask airway (ILMA) in Mallampati class 3 or 4 patients. METHODS Two hundred adults, ASA I-II, Mallampati class 3 or 4, undergoing elective surgery under general anaesthesia were enrolled. All the patients were randomly allocated to either normal or reverse gro...

OBJECTIVE Obstructive sleep apnea (OSA) is a common sleep breathing disorder. Untreated OSA may lead to a number of cardiovascular complications. Dentists may play an important role in OSA detection by conducting careful oral examinations. This study focused on the correlation of oral anatomical features in Thai patients who presented with OSA. METHODS We conducted a prospective comparative s...

klippel-feil syndrome is known by the classic triad of shortness of the neck , limitation of neck movements, and a low posterior hairline. there are often accompanying cervical spinal abnormalities such as kyphoscoliosis as well as urogenital and cardiac abnormalities. presented here we have a 20 year old young man with hypoesthesia and decreased motor function in the right hand. the problem be...
