A new technique improves airway mapping clarity in bronchoscopy, suggesting confidence for pulmonologists.
Accurate navigation within the bronchial tree is essential for successful bronchoscopic sampling of peripheral pulmonary lesions. It fundamentally comprises a series of di/trichotomous decisions as the bronchoscope is advanced through sequential airway generations. This letter describes a simplified, pen-and-paper method for bronchial branch tracing that minimizes distracting complexity and streamlines airway mapping into reproducible steps that can be rapidly performed with reference to pre-procedural CT images. By anchoring navigation in anatomical recognition and spatial awareness, this technique offers both a reliable primary strategy and a dependable fallback option for bronchoscopists seeking clarity and confidence in the procedural suite.
