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.
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 ( = 120 glands), using either CMUT-US or TUS to guide injection. The cadavers were dissected to identify whether the dye was accurately injected into each site.
The accuracies of CMUT-US and TUS-guided injections in the parotid gland were 95.0% ( = 40) and 90.0% ( = 40), respectively ( = 0.69). In the submandibular gland, the accuracies for the CMUT-US ( = 20) and TUS ( = 20) were both 75.0% ( = 0.72). Across all salivary gland sites, injection accuracy was 88.3% ( = 60) using TUS versus 85.0% ( = 60) using CMUT-US ( = 0.79). No significant differences between modalities were seen in the accuracy of injection based on injection subsite, laterality, cadaver sex, or age.
This pilot study demonstrates that CMUT-US-guided salivary gland injection offers similar high accuracy and reproducibility to TUS-guided injection.

超声（US）是一种成熟的用于评估头颈部解剖结构的成像方式。蝴蝶iQ是一种手持式超声设备，它使用半导体硅芯片阵列（电容式微机电超声换能器，CMUT）而非传统超声（TUS）所使用的压电晶体，但其在唾液腺成像及相关经皮操作方面的准确性尚未得到研究。我们旨在进行一项尸体初步研究，以确定CMUT-US在腮腺和颌下腺成像及引导经皮腺体注射方面的实用性和逼真度。
一名耳鼻喉科医生在20具尸体（n = 120个腺体）上双侧地将0.5 mL染料注射到三个不同的唾液腺部位（两个腮腺内部位和一个颌下腺部位），使用CMUT-US或TUS引导注射。对尸体进行解剖以确定染料是否准确注射到每个部位。
CMUT-US和TUS引导下腮腺注射的准确率分别为95.0%（n = 40）和90.0%（n = 40）（P = 0.69）。在颌下腺，CMUT-US（n = 20）和TUS（n = 20）的准确率均为75.0%（P = 0.72）。在所有唾液腺部位，TUS引导注射的准确率为88.3%（n = 60），而CMUT-US引导注射的准确率为85.0%（n = 60）（P = 0.79）。基于注射亚部位、侧别、尸体性别或年龄，不同方式在注射准确性方面未见显著差异。
这项初步研究表明，CMUT-US引导的唾液腺注射与TUS引导的注射具有相似的高准确性和可重复性。
