Abstract：
OBJECTIVE: To evaluate the suitability of a Doppler ultrasound probe in detecting the greater palatine artery or its greater branches non-invasively.
METHODS: The palatal mucosa of 108 participants (median age 34 years, 51 female) was systematically divided into transversal sectors, each aligning with the positions of the upper molars (M), premolars (P) and canine teeth (C), aiming to facilitate precise and consistent localization of the detected palatal blood vessel across different patients. Blood flow of the palatal blood vessels, presumably, was located by scanning the palatal vault bilaterally using an 8-MHz ultrasound probe linked to a transducer. The distance to the corresponding tooth was measured using a millimetre-scale periodontal probe.
RESULTS: Within the regions of M2 to P1, the ultrasound transducer gave a delimitable acoustic pulse signal in 80%-98% of all measurements. The measured median distances between the determined position of the artery and the corresponding teeth ranged from 13 to 15 mm, with smaller distances in the anterior region. In several sectors, the distance was significantly higher for men (C: p = .048; P1: p = .041, M1: p < .01; M2: p = .034).
CONCLUSIONS: Use of the Doppler ultrasound transducer might be a promising approach to non-invasively detect relevant palatine blood vessels preoperatively. It, therefore, might have the potential to reduce the risk of accidental injury during palatal surgery.

摘要：
目的：评估多普勒超声探头在非侵入性检测腭大动脉或其较大分支中的适用性。
方法：108名参与者的腭黏膜（中位年龄34岁，51名女性)被系统地划分为横向部门，每个与上磨牙（M）的位置对齐，前磨牙（P）和犬齿（C），旨在促进在不同患者中检测到的腭血管的精确和一致的定位。腭血管的血流,据推测,通过使用连接到换能器的8MHz超声探头对pal穹顶进行双侧扫描来定位。使用毫米级牙周探针测量到相应牙齿的距离。
结果：在M2至P1的区域内，超声换能器在所有测量的80％-98％中给出了可定界的声脉冲信号。测得的确定的动脉位置与相应的牙齿之间的中值距离范围为13至15mm，前部区域的距离较小。在几个部门，男性的距离明显更高(C:p=.048;P1:p=.041,M1:p<.01;M2:p=.034)。
结论：使用多普勒超声换能器可能是一种有希望的方法，用于术前非侵入性地检测相关的腭血管。It,因此,可能有可能降低腭手术过程中意外损伤的风险。
