In this study, we aimed to investigate the effects of head and neck positions on the visualization of glottis and the success of intubation during videolaryngoscopy in obese patients.
Tree different head and neck positions will compare for glottic visualization and intubation success rates in obese patients (BMI\> 30 kg / m2) who required endotracheal intubation for general anesthesia between 18-65 years of age.

Patient's laryngoscopy will be done using McGrath Mac video laryngoscope
Gaziosmanpasa University Hospital
Tokat Province, Merkez, Turkey (Türkiye)
Glottic view
the percentage of glottic opening (POGO) and cormack-lehane scores will be used to rate of the glottic view
Time frame: During laryngoscopy
Intubation Success
Intubation attempt number will be recorded
Time frame: During intubation
Intubation difficulty
Intubation Difficulty Scale(IDS) score will be recorded.The IDS score is derived from seven variables. N1 represents the number of additional intubation attempts, N2 represents the number of additional operators, N3 is the number of alternative intubation techniques used; N4 represents the laryngoscopic view, N5 represents the lifting force applied during laryngoscopy, N6 represents the necessity to apply external laryngeal pressure to optimize glottic exposure, N7 represents the mobility of vocal cord. The IDS score is the sum of all variables and ranges from zero to infinity. A score of 0 indicates an easy tracheal intubation. Intubation is considered difficult if the score is greater than 5.
Time frame: During Laryngoscopy
Intubation time
The duration of the endotracheal tube placement will be recorded
Time frame: During Intubation
