Difficult laryngoscopy--the "anterior" larynx and the atlanto-occipital gap.
The atlanto-occipital distance is the major factor which limits extension of the head on the neck. It varies widely in the population at large. When the posterior tubercle of the atlas is already in contact with the occiput in the neutral position, attempts to extend the head result in anterior bowing of the cervical spine, and forward displacement of the larynx. This may be a cause of difficul...
متن کاملNeck circumference to thyromental distance ratio: a new predictor of difficult intubation in obese patients.
BACKGROUND This study was performed to assess whether intubation is more difficult in obese patients and to assess the ability of a new index: the ratio of the neck circumference to thyromental distance (NC/TM), to predict difficult intubation in obese patients. METHODS The incidence of difficult tracheal intubation in 123 obese (BMI≥27.5 kg m(-2)) and 125 non-obese patients was compared. Dif...
متن کاملDifficult Intubation in Patient with Short Thyromental Distance: Usefulness of Tongue Traction Maneuver
Introduction: Short Thyromental Distance (TMD; <5 cm) has been correlated with difficult direct intubation in adult patients. Differences in patient characteristics may influence the incidence of difficult airway intubation, especially in patients with a reduced mandible dimension. We report a case affected by Goldenhar’s syndrome treated for mandibular hypoplasia with difficulties in intubatio...
متن کاملAn assessment of the ratio of height to thyromental distance compared to thyromental distance as a predictive test for prediction of difficult tracheal intubation in Thai patients.
BACKGROUND AND RATIONALE Preoperative evaluation is important in the detection of patients at risk for difficult tracheal intubation. Thyromental distance (TMD) is often used for these purposes, but its value as an indicator for difficult intubation is questionable, as it varies with patient size and body proportions. The purpose of the present study was to evaluate and compare the accuracies o...
متن کاملA patient with subcutaneous emphysema following endotracheal intubation.
Difficult intubation can be found in 11% of emergency tracheal intubations.1 Predictors of difficult tracheal intubation have been described, such as mouth opening, Mallampati classification, atlanto-occipital joint extension, mandibulohyoid distance, inter-incisor distance, thyromental distance, sternomental distance, obesity, and a previous history of difficult intubation.2 The occurrence of ...
