ASA (American Society of Anesthesiologists) I-II
Body Mass Index (BMI) >35 kg/m2
Laparoscopic weight reduction surgery (sleeve gastrectomy)
Under general anaesthesia with endotracheal intubation.
Patients (Patients who had upper airway pathologies (maxillo-facial fracture, tumours, etc), pathology causing limitation in head-neck movement (cervical spine fractures, rhomatoid artiritis, ankylozan spondilitis, etc), contraindication of general anaesthesia (history of malign hiperthermia, full stomach, etc) or a history of difficult laryngoscopy or intubation were excluded from study.
Mallampati test, mouth opening, sternomental distance, thyromental distance, upper lip bite test, neck circumference were recorded. The distance from the skin to the anterior aspect of the trachea was measured at three different levels: vocal cords (zone 1), thyroid isthmus (zone 2) and suprasternal notch (zone 3). An anaesthesiologist who were unaware of the clinical screening variables and ultrasonography results performed laryngoscopy. When second attempt for intubation was failed, to use of other difficult intubation equipments were planned. Each participant was followed up until the end of the operation
