Persistent stapedial artery associated with otosclerosis
1Department of Otolaryngology, Kobe City General Hospital, Japan.
Summary
This study details a successful stapedectomy in a patient with bilateral otosclerosis and a persistent stapedial artery. Surgical intervention led to significant hearing improvement in both ears.
Area of Science:
- Otolaryngology
- Vascular Anatomy
- Surgical Otology
Background:
- Otosclerosis is a common cause of conductive hearing loss.
- A persistent stapedial artery is a rare anatomical variation encountered during stapedectomy.
- This variation can complicate the surgical procedure and lead to intraoperative hemorrhage.
Purpose of the Study:
- To report a case of bilateral otosclerosis with a persistent stapedial artery.
- To describe the surgical management of this specific anatomical variation.
- To evaluate the audiological outcome after stapedectomy.
Main Methods:
- A 43-year-old female patient with diagnosed bilateral otosclerosis underwent stapedectomy.
- A persistent stapedial artery, 0.4 mm in diameter, was identified and sectioned in the left ear.
- Hemorrhage was controlled, and the stapes prosthesis was placed.
Main Results:
- Successful sectioning of the persistent stapedial artery was achieved.
- Hemorrhage was effectively controlled during the procedure.
- The patient experienced satisfactory hearing gain in both ears post-stapedectomy.
Conclusions:
- Stapedectomy is feasible and effective in patients with otosclerosis, even with a persistent stapedial artery.
- Careful identification and management of vascular anomalies are crucial for successful outcomes.
- This case highlights the importance of anatomical awareness in otologic surgery.
