Summary
The transmaxillary approach effectively treats inferior orbital venous varices, offering symptom relief and preventing recurrence. This minimally invasive technique preserves orbital structures and function.
Area of Science:
- Ophthalmology
- Neurosurgery
- Vascular Surgery
Background:
- Optimal surgical management for orbital venous varices, especially in the inferior orbit, is debated.
- The transmaxillary approach presents a less invasive alternative to transnasal methods, avoiding nasal cavity and medial maxillary wall disruption.
Purpose of the Study:
- To detail a transmaxillary technique for ligating inferior orbital venous varices.
- To achieve symptom relief and prevent recurrence of venous varices.
Main Methods:
- A single-stage transmaxillary approach was utilized, guided by the second division of the trigeminal nerve (V2).
- The technique involved ligating a venous varix located between the inferior rectus and medial rectus muscles.
Main Results:
- Postoperative imaging confirmed complete obliteration of the venous varix.
- The patient experienced immediate symptom relief without neurological deficits.
Conclusions:
- The transmaxillary approach is a safe and effective method for inferior orbital lesion resection.
- This technique yields excellent clinical outcomes, preserving orbital structures and function.
