Traditional Cold Steel Adenoidectomy (TCSA) and Endoscopic-Assisted Cold Steel Adenoidectomy (EACSA) frequently employ surgical adenoid removal methods. While these techniques effectively treat adenoid- related conditions, their influence on patients' psychological well-being still needs to be more adequately explored. With the increasing focus on the significance of mental well-being in surgical results, this study sought to explore and differentiate the psychological impacts of TCSA and EACSA. The primary objective was to examine and compare anxiety levels between TCSA and EACSA groups. Secondary objectives included evaluating surgical apprehension, post- surgery psychological well-being, procedural satisfaction, postoperative pain, duration until return to daily activities, and occurrence of postoperative complications. In a prospective, randomized controlled trial, 100 patients undergoing adenoidectomy were randomly allocated to the TCSA or EACSA group. The Hospital Anxiety and Depression Scale (HADS) was employed to evaluate anxiety levels at one week, one month, and three months following the surgery. Additional outcomes included surgical apprehension, post-surgery psychological well-being, procedural satisfaction, postoperative pain, time until return to daily activities, and postoperative complications. The EACSA group exhibited significantly lower HADS scores, surgical apprehension scores, and postoperative pain, alongside higher post-surgery psychological well-being scores and procedural satisfaction compared to the TCSA group (p < 0.05). Moreover, the EACSA group had a significantly shorter duration until the return to daily activities (p < 0.05). There were no significant variations found between the groups in terms of either the amount of bleeding during the procedure or the length of the operation. However, the EACSA group demonstrated a lower occurrence of postoperative complications, such as bleeding and infection. The results indicate that EACSA may provide benefits over TCSA in terms of reduced anxiety levels, surgical apprehension, postoperative pain, time until return to daily activities, and enhanced post-surgery psychological well-being and patient satisfaction. These findings could support clinicians in making informed decisions and offering patient counselling when choosing the most appropriate surgical technique based on patients' psychological health. Nevertheless, additional research is required to assess the enduring psychological consequences of these methods.
