Injury to the internal carotid artery during procedures performed in the tonsillar fossa can be catastrophic. Tonsillectomy or uvulopalatopharyngoplasty was performed on 32 patients at the Hospital of the University of Pennsylvania or the Children's Hospital of Philadelphia. Using Doppler ultrasonography, the course of the internal carotid artery in the postsurgical tonsillar fossa was mapped. The results indicate that, in the majority of patients, the internal carotid artery is located between 20% and 60% of the total width across the tonsillar fossa, as measured from the posterior pillar. Appreciation of the surgical anatomy of the tonsillar fossa with respect to the internal carotid artery should contribute to improved intraoperative judgment and further limit the risk of vascular injury during oropharyngeal procedures.
在扁桃体窝进行手术时，颈内动脉损伤可能是灾难性的。宾夕法尼亚大学医院或费城儿童医院对32例患者进行了扁桃体切除术或悬雍垂腭咽成形术。使用多普勒超声对术后扁桃体窝内颈内动脉的走行进行了定位。结果表明，在大多数患者中，从后柱测量，颈内动脉位于扁桃体窝总宽度的20%至60%之间。了解扁桃体窝相对于颈内动脉的手术解剖结构，应有助于提高术中判断力，并进一步降低口咽手术期间血管损伤的风险。
