[One case report of nasal sinus ossification]

Area of Science:

• Otolaryngology and Orbital Surgery
• Pediatric Oncology
• Medical Imaging

Background:

• Osteofibromas are rare benign bone tumors that can affect craniofacial structures.
• Orbital and sinonasal osteofibromas in pediatric patients present unique diagnostic and surgical challenges.
• Early diagnosis and intervention are crucial to prevent complications such as proptosis and vision impairment.

Observation:

• An 8-year-old male presented with a one-month history of left eye proptosis (bulging).
• Physical examination revealed lateral nasal wall movement and a narrowed left nasal cavity.
• Orbital CT imaging demonstrated extensive damage to the left ethmoid sinus, maxillary sinus, sphenoid sinus, and nasal cavity.

Findings:

• A complex osteofibroma involving multiple sinonasal and orbital structures was diagnosed.
• Surgical resection was performed using a combined approach targeting the left maxillary, ethmoid, and sphenoid sinuses.
• Histopathological examination confirmed the diagnosis of osteofibroma.

Implications:

• Combined surgical approaches can effectively resect extensive sinonasal and orbital osteofibromas in children.
• This case highlights the importance of multidisciplinary collaboration in managing rare pediatric tumors.
• Successful surgical management led to satisfactory recovery and a long-term absence of recurrence, preserving ocular and sinonasal function.
