The Effect of Thyromental Height and Other Difficult Airway Evaluation Parameters

Many changes occur in the body with age. There are difficulties in endotracheal intubation and the placement of supraglottic airway devices (LMA) in elderly patients due to changes in the tooth and facial structure, and a decrease in temporomandibular joint and neck movements.
