Summary
This study reports the first pediatric case of an odontogenic myxoma, a rare tumor, causing orbital involvement. The tumor presented as facial swelling and nasal obstruction in a young child.
Area of Science:
- Oral and Maxillofacial Surgery
- Pediatric Oncology
- Ophthalmology
Background:
- Odontogenic myxomas are rare benign tumors typically affecting adults.
- Orbital involvement is exceptionally uncommon, especially in pediatric cases.
Observation:
- A 15-month-old female presented with unilateral facial swelling, nasal obstruction, and nasal deviation.
- Computed tomography revealed a cystic maxillary sinus mass disrupting the medial orbital floor.
- Initial biopsy was non-diagnostic, with rapid tumor growth necessitating surgical excision.
Findings:
- Histopathology confirmed the mass as an odontogenic myxoma.
- Surgical removal via combined lateral rhinotomy and sublabial approaches revealed a significant orbital floor defect extending to the orbital apex.
- This represents the first documented instance of orbital involvement by an odontogenic myxoma in a pediatric patient.
Implications:
- Highlights the importance of considering rare tumors in pediatric facial masses with orbital extension.
- Underscores the need for advanced imaging and potentially aggressive surgical management in pediatric odontogenic myxomas.
- Contributes novel data to the understanding of odontogenic myxoma presentation and behavior in children.
