Summary
Maxillary ameloblastoma, a rare tumor, can invade the orbit and cause vision loss. Early detection and monitoring are crucial for managing this locally aggressive odontogenic tumor.
Area of Science:
- Ophthalmology
- Oral and Maxillofacial Surgery
- Oncology
Background:
- Ameloblastoma is a rare odontogenic tumor originating from the jaw.
- Orbital invasion by maxillary ameloblastoma is uncommon in ophthalmic practice.
Observation:
- Two patients presented with new ocular and orbital symptoms due to recurrent maxillary ameloblastoma.
- One patient experienced recurrence with orbital invasion, requiring orbital exenteration.
- The second patient had intracranial and orbital invasion, necessitating extensive resection.
Findings:
- Maxillary ameloblastoma can recur and exhibit local aggressiveness.
- Orbital invasion by ameloblastoma can lead to significant ocular morbidity.
- Surgical management varied based on the extent of invasion, including orbital exenteration and intracranial resection.
Implications:
- Ophthalmologists must be aware of maxillary ameloblastoma as a potential cause of orbital invasion.
- Close monitoring is essential for patients with suspected orbital involvement.
- Prompt diagnosis and multidisciplinary management are key to improving outcomes.
