The foramen of Huschke or foramen tympanicum is a developmental defect in the bony part of the external auditory meatus. It occurs due to incomplete obliteration of the tympanic canal and the persistence of openings along the canal. This leads to the presence of a salivary fistula and the most common symptoms of the condition are otalgia, otorrhea, and hearing loss. We report a case of a 69-year-old female patient who presented to the ENT with symptoms of watery discharge from the left ear for 12 years. In the last two weeks, pain and itching appeared. Otoscopy showed the presence of a clear fluid in the external auditory meatus with a normal tympanic membrane. Biochemical analysis of the fluid proved the presence of amylase. Computed tomography showed a fistula between the parotid gland and the external ear canal. The diagnosis of the persistent foramen of Huschke remains difficult due to the fact that it could mimic many other conditions. The otalgia and otorrhea are symptoms that suggest a very wide differential diagnosis. Misdiagnosis and inappropriate treatment are common.
胡施克孔或鼓室孔是外耳道骨性部分的一种发育缺陷。它是由于鼓室管未完全闭塞以及沿该管的开口持续存在而发生的。这会导致涎瘘的出现，该病症最常见的症状是耳痛、耳漏和听力损失。我们报告一例69岁女性患者，她因左耳流水12年就诊于耳鼻喉科。在过去两周，出现了疼痛和瘙痒。耳镜检查显示外耳道有清亮液体，鼓膜正常。对该液体的生化分析证实存在淀粉酶。计算机断层扫描显示腮腺与外耳道之间存在瘘管。由于胡施克孔持续存在可能会模仿许多其他病症，因此其诊断仍然困难。耳痛和耳漏是提示鉴别诊断范围非常广泛的症状。误诊和不恰当的治疗很常见。
