Feasibility of In-office Fine-Needle Aspiration for Base of Tongue Tumors.

We aim to demonstrate the feasibility of in-office transcervical ultrasound (TCUS)-guided fine-needle aspiration (FNA) of base of tongue (BOT) tumors in a single-institution. Retrospective chart review was performed and 3 patients met criteria, with BOT tumors ≥3 cm . Two patients had no cervical adenopathy, while FNA of a cervical lymph node was inconclusive in patient 3. Two patients had multiple medical comorbidities rendering them high risk for general anesthesia, and 1 patient had a BOT tumor obscuring visualization of the glottis, which would have precluded intubation and potentially required tracheostomy to proceed. All patients underwent successful in-office TCUS-guided FNA, with results showing squamous cell carcinoma. There were no related complications. In-office TCUS-guided FNA can be used for diagnosis of BOT lesions that are evident on ultrasound. This is beneficial in cases where general anesthesia is considered high risk. Additionally, 1 patient safely continued anticoagulation, and another was able to avoid tracheostomy. This technique is cost-effective as it avoids the expenses associated with operative intervention.
