The CamStylet is a lightweight, smartphone-connected video stylet designed to provide real-time visualization without the need for external monitors. Methods: In this randomized clinical trial, 180 adults undergoing elective surgery were allocated to direct laryngoscopy (DL) or laryngoscopy assisted by the CamStylet. Standardized anesthetic and intubation protocols were used. Intubation time, glottic view, first-attempt success, need for external laryngeal manipulation, and oxygen desaturation were recorded. Data from 176 patients were analyzed. Results: Intubation time was slightly longer with the CamStylet, but first-pass success was high in both groups. The CamStylet provided a clearer glottic view and markedly reduced the need for external laryngeal pressure. Rates of desaturation and requirement for rescue videolaryngoscopy were low and comparable between groups. No major adverse events occurred. Conclusion: Although the CamStylet added a few seconds to intubation time, it improved visualization and reduced the need for external manipulation. Its portability and rapid setup may make it a practical adjunct in settings where VLs are limited or unavailable. Further evaluation in difficult airway scenarios is warranted. https://aacc.tums.ac.ir/index.php/aacc/article/view/1555
