Summary
Brief summary (as posted)
This is a prospective observational study.The purpose of this study is to predict difficult intubation with ultrasonographic evaluation combined with preoperative physical examination in patients diagnosed with acromegaly and planned for pituitary surgery.

- Participants diagnosed with acromegaly
- description
- All ultrasonographic assessments will be performed preoperatively by anesthesiologists who have prior experience using ultrasound. Participants will be positioned in the supine position with the head and neck in neutral alignment. Measurements of the skin-hyoid bone, skin-epiglottis, and skin-anterior commissure of the vocal cords distances will be. Endotracheal intubation of the participants will be performed by anesthesiologists who are unfamiliar with the ultrasonographic measurements. During the intubation, the use of adjuncts, the need for cricoid pressure, the number of additional interventions, the number of additional operators, and the glottic opening seen during laryngoscopy will be recorded according to the Cormack-Lehane classification without external pressure. If necessary, advanced airway devices (videolaryngoscopy, flexible fiberoptic laryngoscopy) will be used.
