OBJECTIVE: Ultrasound (US) is a well-established imaging modality for the evaluation of head and neck anatomy. The Butterfly iQ is a handheld ultrasound device that uses a semiconductor silicon chip array (capacitive micromachined ultrasound transducers, CMUT) instead of piezoelectric crystals used by traditional ultrasounds (TUS), but its accuracy has not been investigated with respect to salivary gland imaging and associated transcutaneous procedures. We aimed to perform a pilot cadaver study to determine the utility and fidelity of the CMUT-US for parotid and submandibular gland imaging and guiding transcutaneous gland injection. METHODS: One otolaryngologist injected 0.5 mL of dye into three distinct salivary gland sites (two intraparotid sites and one submandibular gland site) bilaterally on 20 cadavers ( RESULTS: The accuracies of CMUT-US and TUS-guided injections in the parotid gland were 95.0% ( CONCLUSION: This pilot study demonstrates that CMUT-US-guided salivary gland injection offers similar high accuracy and reproducibility to TUS-guided injection. LEVEL OF EVIDENCE: V.
