Summary
Persistent foramen of Huschke (FH) can cause ear pain and discharge. Surgical intervention offers a durable resolution for symptomatic patients with this uncommon condition.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Imaging
Background:
- Persistent foramen of Huschke (FH) is an uncommon congenital anomaly.
- It can lead to various otologic symptoms, often being underdiagnosed.
Purpose of the Study:
- To describe the clinical presentation of symptomatic persistent FH.
- To outline the management strategy and outcomes for affected patients.
Main Methods:
- Retrospective review of adult patients with radiographically confirmed persistent FH.
- Evaluation of clinical presentation, diagnostic findings, and surgical management.
- Assessment of symptom resolution post-intervention.
Main Results:
- Four patients with symptomatic persistent FH were identified.
- Common symptoms included otalgia and otorrhea; one patient had conductive hearing loss.
- All patients underwent surgical repair (preauricular or transcanal) with complete symptomatic resolution.
Conclusions:
- Persistent FH is an underrecognized cause of otologic symptoms.
- Diagnosis relies on clinical suspicion, physical examination, and imaging.
- Surgical intervention provides effective and lasting symptom relief.
