Summary
Persistent stapedial artery, a rare condition, was identified during stapes surgery. This case highlights challenges and presents an all-Teflon prosthesis as a viable solution for this anatomical variation.
Area of Science:
- Vascular anatomy
- Otology
- Surgical techniques
Background:
- The stapedial artery is a transient fetal vessel, typically obliterated after birth.
- Persistence of the stapedial artery is an uncommon congenital anomaly.
- Its presence can complicate middle ear surgeries, particularly stapedotomy.
Observation:
- A case of persistent stapedial artery encountered during stapes surgery is presented.
- The artery was observed directly overlying the footplate.
- Technical difficulties during the procedure due to the anomalous vessel were noted.
Findings:
- An all-Teflon prosthesis was successfully used in the presence of the persistent stapedial artery.
- Previous reports utilized wire prostheses for similar cases.
- Post-operative CT scan confirmed the vessel's location within the middle ear.
Implications:
- This case demonstrates the successful use of an all-Teflon prosthesis in managing stapes surgery with a persistent stapedial artery.
- It adds to the understanding of managing this rare vascular anomaly.
- Further research into optimal prosthetic choices for such anatomical variations is warranted.
