Pediatric Benign Fibro-Osseous Lesions of the Nose and Paranasal Sinuses: A Tertiary Hospital Experience.

Background: Pediatric benign fibro-osseous lesions of the nose and paranasal sinuses are considered rare neoplastic entities. These fibro-osseous lesions are difficult to accomplish owing to the multifaceted anatomy of the skull base in addition to the closeness to neurovascular configurations.

Objective: The study aimed to study different clinical presentations, radiological manifestations, surgical management, and consequences of different benign fibro-osseous lesions in the pediatric age groups.

Aggressive juvenile ossifying fibroma of the ethmoid sinus with orbital and intracranial extension: A case report.

Background: Juvenile ossifying fibroma is a rare benign destructive lesion of nose and paranasal sinuses. It occurs in the craniofacial bones of children below 15 years of age. It is usually discovered in the mandible and maxilla and rarely in the paranasal sinuses.

Pediatric allergic fungal rhinosinusitis with extensive intracranial extension - Case report and literature review.

Introduction: Over the last two decades, allergic fungal sinusitis (AFRS) has become increasingly common. It's defined as a noninvasive, benign inflammatory fungal disease of the sinuses which develops in young adults and adolescents. Patients often complain of symptoms like nasal obstruction, congestion, purulent or clear rhinorrhea, anosmia, and headache.

Bilateral simultaneous sino-nasal inverted papilloma; A report of two cases and literature review.

Introduction: Inverted Papilloma is a benign sinonasal tumor with a high recurrence rate and potential for malignant transformation, it typically presents as an obstructing unilateral nasal mass, atypical presentations include bilateral involvement which occurs in up to 5 % of cases.

Case Presentation: Here we present two different cases of bilateral inverted papilloma, both presented complaining of bilateral nasal obstruction, the second case also had associated nasal polyposis and history of multiple previous endoscopic sinus surgeries, both cases were managed with endoscopic medial maxillectomy and tumor removal, with no signs of recurrence on follow up.

Conclusion: Bilateral involvement is an uncommon, atypical presentation of inverted papilloma, endoscopic surgery is a safe, reliable approach and it is the mainstay of treatment, regular endoscopic and clinical follow up is important for detection of recurrence.
