To determine the prevalence of radiographic empty sella in patients with spontaneous cerebrospinal fluid (CSF) otorrhea.
Retrospective case series of adult patients with CSF otorhinorrhea at an academic tertiary medical center. Patients with history of skull base surgery, trauma, tumor, or chronic ear disease were excluded. Available imaging studies were reviewed with attention to the sella turcica.
Eight patients were diagnosed with spontaneous CSF otorrhea. Five of seven patients with adequate imaging studies (71%) had a radiographic empty sella. Seven of eight patients were clinically obese, with a body mass index BMI>30 kg/m2.
Empty sella is a common radiologic finding in patients with spontaneous CSF otorrhea. This supports the theory that increased intracranial pressure contributes to development of spontaneous CSF otorrhea.
Radiographic empty sella predicts elevated intracranial pressure, which may require further evaluation and treatment in patients with spontaneous CSF otorrhea.

确定自发性脑脊液耳漏患者中影像学空蝶鞍的患病率。
在一家学术性三级医疗中心对成年脑脊液耳鼻漏患者进行回顾性病例系列研究。排除有颅底手术、创伤、肿瘤或慢性耳部疾病史的患者。对现有的影像学研究进行回顾，重点关注蝶鞍。
8例患者被诊断为自发性脑脊液耳漏。7例有充分影像学研究的患者中有5例（71%）存在影像学空蝶鞍。8例患者中有7例临床肥胖，体重指数（BMI）>30 kg/m²。
空蝶鞍是自发性脑脊液耳漏患者常见的影像学表现。这支持了颅内压升高导致自发性脑脊液耳漏发生的理论。
影像学空蝶鞍预示颅内压升高，这可能需要对自发性脑脊液耳漏患者进行进一步评估和治疗。
