• Background The aim of this study was to investigate the feasibility of flexible endoscopy‐guided tracer injection for sentinel lymph node (SLN) identification in patients with laryngeal and pharyngeal carcinoma. Methods Sixteen cT1‐4N0‐2M0 patients with laryngeal or pharyngeal carcinoma underwent intra‐ and peritumoral [99mTc]Tc‐nanocolloid injections after topical anesthesia under endoscopic guidance. SPECT–CT scans were performed at two time points. Results Tracer injection and visualization of SLNs was successful in 15/16 (94%) patients. Median number of tracer injections was 1 intratumoral and 3 peritumoral. The median duration of the endoscopic procedure including tracer injection after biopsy taking was 7 min (range 4–16 min). A total of 28 SLNs were identified which were all visualized on the early and late SPECT–CT. Most SLNs were visualized in neck levels II and III. Conclusions Flexible endoscopy‐guided tracer injection for SLN identification is a feasible and fast procedure in laryngeal and pharyngeal carcinoma patients.
