Summary
Glomus tympanicum, a benign middle ear tumor, can be challenging to diagnose due to its location. This case highlights successful diagnosis and surgical resection of glomus tympanicum using advanced imaging and embolization techniques.
Area of Science:
- Otolaryngology
- Neurosurgery
- Radiology
Background:
- Glomus tympanicum tumors are slow-growing, benign neoplasms originating from paraganglia in the middle ear.
- Distinguishing glomus tympanicum from other middle ear masses can be difficult, particularly when obscured by an intact tympanic membrane.
- These tumors can cause local destruction and symptoms like unilateral hearing loss and tinnitus.
Observation:
- A 40-year-old female presented with unilateral deafness and tinnitus.
- Otoscopy revealed a red, bulging mass behind an intact tympanic membrane, with mild conductive hearing loss.
- MRI confirmed an intensely enhancing lesion in the mesotympanum and hypotympanum.
Findings:
- Clinical, audiological, and radiological findings led to a diagnosis of glomus tympanicum.
- Pre-operative embolization was performed 48 hours prior to surgical resection.
- Complete tumor resection was achieved through microsurgery.
Implications:
- This case underscores the importance of a multidisciplinary approach in diagnosing and managing glomus tympanicum.
- Effective pre-operative embolization can significantly reduce intraoperative hemorrhage.
- Microsurgical resection remains a viable and effective treatment option for glomus tympanicum.
