Summary
Rhinosurgery can cause permanent vision loss due to ophthalmic artery issues or direct surgical trauma. These rare complications highlight the risks associated with nasal surgeries and anesthetic techniques.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
- Vascular Surgery
Background:
- Rhinosurgery, a common procedure, carries potential risks.
- Visual impairment following nasal surgery is a rare but serious complication.
Observation:
- Three cases of unilateral permanent severe visual impairment after rhinosurgery are presented.
- Two cases involved vascular disturbances in ophthalmic arteries.
- One case resulted from direct surgical trauma and infarction.
Findings:
- Vascular complications may stem from intra-arterial injection of local anesthetics with adrenaline.
- Retrograde flow into ophthalmic arteries is a plausible mechanism.
- Direct surgical trauma to ocular structures or related infarction can cause vision loss.
Implications:
- This underscores the importance of careful anesthetic administration during rhinosurgery.
- Awareness of potential vascular and traumatic complications is crucial for patient safety.
- Further research into preventative measures for visual impairment after rhinosurgery is warranted.
