Summary of Primary Orbital Intraosseous Venous Malformation (OIVM) Study
New Information: This study provides a detailed analysis of six cases of OIVM, a rare condition, with a focus on clinical presentation, radiological features, and management strategies, alongside a comprehensive literature review.
Importance: The study emphasizes the need for awareness among ophthalmologists about OIVM due to its rarity, potential for significant intraoperative blood loss, and the preferred treatment approach.
Contribution to Literature: The study adds valuable data on OIVM, including demographic distribution, symptomatology, affected bones, radiological findings, treatment modalities, and outcomes, contributing to the limited existing literature on this condition.
Results: The study included five females and one male with an average age of 30 years. Proptosis was the most common symptom, affecting 83.33% of cases. The frontal and zygomatic bones were frequently involved. CT scans typically showed expansile bony lesions. Treatment strategies varied, with 50% undergoing pre-operative embolization and en bloc excision, 16.66% managed with partial excision, and 33.33% followed up after biopsy. No recurrences or progression were observed during follow-ups ranging from 6 to 48 months.
Clinical Relevance: The study highlights the importance of complete excision and reconstruction for OIVM, with no known recurrences, guiding clinicians in the management of this rare entity.
