Awake flexible bronchoscopy was well tolerated in this study and could serve as a useful diagnostic tool without necessitating anesthetic. However, further study is needed to compare awake flexible bronchoscopy with flexible bronchoscopy under general anesthesia. Additionally, the patients selected for this study were limited to those with minimal risk, such as patients without cardiac disease. Limitations of this technique include suboptimal visualization of subglottic region and limited diagnostic utility for sleep related airway pathologies and cases where therapeutic intervention is needed.
