Background: Obtaining airway security holds the utmost importance in anesthesia. Specific predictive tests or findings for difficult airway are not defined for various pediatric age groups. Anthropometric measurements are defined parallel to percentile curves in different age groups.

Aim: The aim of this study is to find out the value of body mass index and anthropometric measurements in prediction of difficult laryngoscopy in children by comparing to direct laryngoscopic evaluation of Cormack-Lehane test.

Methods: Following institutional ethics committee approval and informed consent of parents of 108 patients (ages 0-3years), undergoing elective surgery were included in this study. Weight, height, body mass index and head circumference of the patients were measured and percentiles were recorded, prior to induction.

Following standard anesthesia induction with thiopental all patients received 0,6 mg.kg-1 rocuronium intravenously. After sufficient time for neuromuscular relaxation laryngoscopy performed and Cormack-Lehane scores recorded. All recorded parameters were compared with Cormack-Lehane scores.

Inclusion Criteria:

• 0-3 years old (1-36 mounts) pediatric patients
• Patients 0-3 age years old with ASA I, undergoing elective surgery were included in this study

Exclusion Criteria:

• Patients with known syndrome, facial anomaly, ASA score above 2 and laryngeal mask aiway were excluded from the study

pediatric patients

Demographic data, head circumference, weight, height measurements, body mass index and percentile values were recorded by a pediatric surgeon who was unaware about the studyin the preoperative period.
