To compare three surgical approaches for excision of the zygomatic gland in dogs.
Cadaveric study.
Cadavers of mesocephalic dogs (n = 20).
Each skull was assigned to a lateral approach with zygomatic arch ostectomy on the left (n = 20) and one approach without ostectomy on the right, ventral (n = 10) or dorsal (n = 10) to the zygomatic arch. Approaches were evaluated for surgical exposure (rated on a scale of 1-5 with one optimal exposure), tissue trauma, and completeness of gland removal. Glands from each side were weighed to compare as internal control.
The ostectomy-based approach offered excellent surgical view and good exposure of the zygomatic gland but caused more tissue trauma. The dorsal nonostectomy approach did not allow complete zygomatic gland extraction in nine of the 10 dogs, whereas the ventral nonostectomy approach enabled complete extraction in all 10 dogs.
The ventral zygomatic approach allowed complete removal of the zygomatic gland, with good surgical overview, while reducing tissue trauma and preserving the zygomatic arch.
The ventral nonostectomy approach should be considered as an alternative to excise the zygomatic gland in dogs.
比较三种用于切除犬颧腺的手术方法。
尸体研究。
中脑型犬的尸体（n = 20）。
将每个颅骨分配至左侧采用颧弓截骨术的外侧入路（n = 20），右侧采用两种不入路方法，一种是位于颧弓腹侧（n = 10），另一种是位于颧弓背侧（n = 10）。评估手术入路的手术暴露情况（以1-5分进行评分，1分为最佳暴露）、组织创伤以及腺体切除的完整性。对每侧的腺体进行称重以作为内部对照进行比较。
基于截骨术的入路提供了极佳的手术视野以及对颧腺的良好暴露，但造成了更多的组织创伤。10只犬中有9只采用背侧非截骨术入路未能完全摘除颧腺，而采用腹侧非截骨术入路的所有10只犬均实现了完全摘除。
腹侧颧入路能够完全摘除颧腺，具有良好的手术视野，同时减少了组织创伤并保留了颧弓。
腹侧非截骨术入路应被视为切除犬颧腺的一种替代方法。
