    Abstract:
    BACKGROUND: Pediatric benign paranasal sinus osteoneogenic tumors have previously been difficult to treat due to the surgical constraints of the developing skull. Progression may lead to intracranial complications or orbital and optic nerve compression. OBJECTIVE: To assess the presentation and management of benign paranasal sinus osteoneogenic tumors. METHODS: Systematic review of the symptoms and surgical treatment of these lesions, and a case series of 2 adolescents with osteomas impinging on the orbit treated with a multiportal approach. RESULTS: Forty-eight cases of osteomas, osteoblastoma, or osteoid osteomas were reviewed from 43 articles. The average age was 14 years, 67% of tumors were osteomas, and 48% were greater than 3 cm in longest dimension. Compared to osteoblastomas, osteomas had a greater male to female ratio (4.3:1; P = .02), presented at older age ( P = .03) with a smaller tumor burden ( P = .003), and had prior trauma or surgery ( P < .001). The ethmoid, frontal, maxillary, and sphenoid sinuses were affected in decreasing order of frequency. A purely endoscopic sinus surgery approach was taken in 31% of cases, open approach in 62% of cases, and combined approach in 7% of cases. Osteoblastoma patients had a 32% rate of recurrence, compared to only 3% among osteoma patients. On univariate logistics regression of patient demographics, tumor characteristics, and surgical approaches predictive of surgical outcomes, only tumor type was predictive of postoperative recurrence (odds ratio: 0.07; 95% confidence interval, 0.007-0.77; P = .029). CONCLUSION: There was no association between surgical approach and postoperative complications or rate of recurrence. However, a transnasal and transorbital multiportal approach avoids facial incisions.
