To describe an intraoral approach (IOA) for zygomatic sialadenectomy in dogs and to compare this surgical approach to a modified lateral orbitotomy approach (LOA).
Cadaveric study and short case series.
Ten canine cadavers and three dogs with clinical disease.
Bilateral zygomatic sialoadenectomies were performed in six mesocephalic, two brachycephalic and two dolichocephalic cadavers, randomly assigned to IOA on one side and LOA on the contralateral side. Duration of surgery, ease of surgical stage scores (rated on 5-point Likert scale) and completeness of gland removal were recorded. Additionally, IOA was performed in three dogs with zygomatic salivary gland (ZSG) disease.
Removal of the ZSG was complete in 8/10 and 10/10 dogs using the IOA and LOA, respectively. Surgery was faster with IOA (42.0 min; 33.5-49.6 min) than LOA (65.7 min; 54.9-76.4 min, p = .005). Ease of removal did not differ between approaches (p = .091). Diseased ZSGs were successfully removed in three dogs without intra- or short-term postoperative complications.
The intraoral approach described here was technically equally challenging but faster than the LOA. Its clinical use led to an uneventful surgery with excellent short-term outcome in three dogs.
The IOA provides an alternative approach for zygomatic sialoadenectomy in dogs with ZSG disease.
描述犬颧唾液腺切除术的口内入路（IOA），并将该手术入路与改良外侧眶切开术入路（LOA）进行比较。
尸体研究和短病例系列。
10只犬尸体和3只患有临床疾病的犬。
对6只中脑型、2只短头型和2只长头型犬尸体进行双侧颧唾液腺切除术，随机将一侧分配为IOA，对侧分配为LOA。记录手术时间、手术阶段难易程度评分（采用5分制李克特量表评分）和腺体切除的完整性。此外，对3只患有颧唾液腺（ZSG）疾病的犬进行IOA。
分别使用IOA和LOA时，8/10只和10/10只犬的ZSG切除完整。IOA手术时间（42.0分钟；33.5 - 49.6分钟）比LOA（65.7分钟；54.9 - 76.4分钟，p = .005）更快。两种入路的切除难易程度无差异（p = .091）。3只犬的患病ZSG成功切除，无术中或术后短期并发症。
本文描述的口内入路在技术上同样具有挑战性，但比LOA更快。其临床应用使3只犬手术顺利，短期预后良好。
IOA为患有ZSG疾病的犬颧唾液腺切除术提供了一种替代方法。
