Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this prospective observational study was to compare these tests used to predict difficult intubation in patients undergoing thyroid surgery. Secondarily; By comparing these tests, we aim to find the test that best predicts difficult intubation and to determine the incidence of difficult intubation in patients who will undergo thyroid surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients' demographic information (age, gender, American Society of Anesthesiologists (ASA) classification, STOP-BANG score(snoring, feeling tired, observed apnea, hypertension, obesity, age, neck circumference and gender), body mass index) and thyroid ultrasonographic measurement will be recorded.

At the preoperative visit, patients will be evaluated for El-Ganzouri Risk Index (EGRI) scores (mouth opening, thyromental distance, mallampati score, neck movement limitation, presence of prognathia, body weight and history of difficult intubation) and for airway ultrasonography (skin-epiglottis distance, skin-hyoid bone distance, skin-vocal cord distance, tongue thickness and tongue volume values).

After this information is recorded, patients will be grouped as those expected difficult intubation and those who are not. After the patients are taken to the operating table and monitored, vascular access will be opened, standard anesthesia induction will be applied to the patients by the room specialist, and laryngoscopy and endotracheal intubation will be performed by the trained (\>2 years experienced) anesthesiologist. If Intubation Difficulty Scale (IDS) score will be greater than 5, patient will be considered difficult intubation.
