Table 1 Comparison of different management techniques for subglottic lesions
Technique | Advantages | Disadvantages |
|---|---|---|
Flexible bronchoscope under ETT Protection | - Good visualization of the subglottic area - Balloon tamponade enables bleeding control - Minimizes risk of tumor dislodgement | - Limited operative space - Requires experienced bronchoscopist and anesthesiologist - Requires tolerance to general anesthesia |
Flexible bronchoscope with LMA | - Preserves spontaneous respiration - Suitable for short diagnostic procedures and therapeutic interventions | - Ineffective bleeding control |
Rigid bronchoscope | - Wide working channel - Suitable for resection of large or hemorrhagic lesions | - Limited visualization of subglottic area - Higher risk of airway trauma |
Interventional embolization | - Minimally invasive - Effective for hypervascular lesions | - Contraindicated in patients with iodine allergy - Not allow biopsy or lesion resection |
Awake fiberoptic intubation | - Contraindicated in patients with iodine allergy - Does not allow biopsy or lesion resection | - Poor patient comfort - Requires patient cooperation |
