Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications. This paper aimed to examine the surrounding anatomy, diagnosis, and treatment of FSOT.
额窦流出道（FSOT）损伤可能发生在额窦骨折和鼻筛眶骨折的病例中。由于FSOT内衬有负责从额窦到鼻腔通道的黏膜，未经治疗的损伤可能导致诸如黏液囊肿形成或慢性额窦炎等并发症。因此，FSOT的评估具有临床意义，FSOT主要通过计算机断层扫描或术中染色来诊断。外科医生在治疗FSOT损伤时有几种选择，他们需要熟悉这些选择以便采取适当的治疗措施，从而遵循FSOT的治疗原则，即安全鼻窦原则，并减少并发症。本文旨在研究FSOT的周围解剖结构、诊断和治疗。
