Comparison of Postoperative Sore Throat Following Endotracheal Intubation Performed With Videolaryngoscope, Videostylet, and Fiberoptic Bronchoscope

This study aims to compare video laryngoscope (VL), video stylet (VS), and fiberoptic bronchoscope (FOB) in elective endotracheal intubations of patients aged 18 to 65 years, classified as ASA I-II and without predicted difficult airways. The primary endpoints are the incidence of postoperative sore throat and hoarseness, while secondary endpoints include intubation time, first-attempt intubation success, hemodynamic responses, and procedure-related complications. Postoperative sore throat and hoarseness will be assessed at the bedside at the 20th minute and 6th hour following extubation.

Inclusion Criteria: * The requirement for endotracheal intubation for general anesthesia during elective surgery in our hospital * Being between 18 and 65 years of age * Having an ASA physical status classification of I or II * Providing informed consent to participate in the study Exclusion Criteria: * Presence of a coagulation disorder * Being identified as a patient with a predicted difficult airway (Patients anticipated to have a difficult airway during standard preoperative anesthesia evaluation and documented as such in the preoperative assessment notes. Relevant criteria include: Mallampati score of 3 or 4, upper lip bite test grade 3, short neck length, abnormal neck anatomy or limited neck mobility, micrognathia/retrognathia, facial deformities/trauma, and mouth opening less than 3 cm.) * Presence of obesity (body mass index \> 35 kg/m²) * Undergoing head and neck surgery in which postoperative sore throat is expected due to the surgical site * Placement of a nasogastric (NG) tube during surgery, which may contribute to postoperative sore throat * Refusal to participate in the study
