Abstract：
OBJECTIVE: Sinus osteotomy is currently performed in equine surgery with conventional surgical methods, such as trephines and oscillating bone saw, leading to subsequent trauma to the bone during cutting. Piezoelectric devices are now used in maxillofacial surgery in humans as a standard tool as it is less traumatic than the oscillating bone saw and shortens the healing period. The aim of this study was to show that the piezoelectric device can be used for equine sinus surgery, compare its use with the oscillating bone saw, and describe the outcome of cases involving osteotomy performed with a piezoelectric surgical device.
METHODS: 10 horse specimens for cadaveric study and 11 client-owned equines for clinical evaluation.
METHODS: Each cadaveric head underwent a frontonasal bone flap on a randomly assigned side with the piezotome and the oscillating bone saw on the opposite side. Surgical time was recorded for every procedure, and gross examination was performed. A Welch t test was used to compare the surgical time between piezoelectric and oscillating saw use. For the clinical study, animals presented for sinonasal surgery at the hospital from March through October 2023 were included.
RESULTS: Osteotomy was possible with the piezotome in all animals. Surgical time was significantly increased when using the piezotome in comparison with the oscillating saw (P < .05). All clinical patients were treated adequately for the sinonasal disorder they were presented for using the piezotome instead of the oscillating saw. No adverse effects nor long-term complications related to its use have been noted, and preservation of the surrounding soft tissues was evident.
CONCLUSIONS: The use of a piezoelectric device in equine surgery is feasible. However, the cadaveric study showed an increased surgical time to perform a frontonasal bone flap.

摘要：
目的：鼻窦截骨术目前在马手术中采用常规手术方法，比如环钻和摆动的骨锯，导致切割过程中骨骼的后续创伤。压电设备现在作为标准工具用于人类的颌面外科手术中，因为它比振荡的骨锯创伤小，并且缩短了愈合时间。这项研究的目的是证明压电设备可用于马窦手术，将它的使用与摆动的骨锯进行比较，并描述用压电手术装置进行截骨手术的结果。
方法：10个用于尸体研究的马标本和11个用于临床评估的客户拥有的马标本。
方法：每个尸体头部在随机分配的一侧接受额鼻骨瓣，压电切片机和振动骨锯在另一侧。记录每个手术的手术时间，并进行了粗略检查。使用Welcht检验来比较压电锯和振荡锯使用之间的手术时间。对于临床研究，包括2023年3月至10月在医院接受鼻窦手术的动物.
结果：在所有动物中，压电切骨术都是可能的。与振荡锯相比，使用压电刀的手术时间显着增加（P<0.05）。所有临床患者均接受了足够的治疗，以治疗他们使用压电刀代替振荡锯的鼻窦疾病。没有注意到与使用有关的不良反应或长期并发症，周围软组织的保存很明显。
结论：在马手术中使用压电设备是可行的。然而,尸体研究显示，进行额鼻骨瓣的手术时间增加。
