Gigantic paranasal sinuses osteomas: clinical features, management considerations, and long-term outcomes

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. Methods and Settings. This is a case series study of a single-center experience.

Results

Four different cases were presented and discussed (osteoma, fibrous dysplasia, and ossifying fibroma.

Conclusion

We reported four different cases of osteoma, ossifying fibroma, and fibrous dysplasia. All of these cases were managed endoscopically with no postoperative complications. Endoscopic management is considered highly effective with reduced morbidity. Preoperative radiographic studies are highly essential for diagnosis and operative planning.

Long-term persistent discomfort due to a giant frontoethmoidal osteoma despite complete surgical removal - A case report

Introduction

Giant frontoethmoidal osteomas are rare, slow-growing, benign osseous tumours, frequently causing severe life impairing symptoms due to their proximity to noble structures. Initially, osteomas are often diagnosed on radiographs by chance. Their aetiology can be considered ambiguous. They may either be treated by active observation, medical therapy, radio and thermal therapy, or surgery.

Case presentation

We report the case of a 56-year-old female patient with a giant osteoma spreading from the nasal cavity to the entire frontoethmoidal sinus, leading to headaches, respiratory problems, and nausea for several years. For a period of 20 years, a watch and wait approach was applied. Finally, the osteoma was removed using a combined open and endoscopic approach. One year after the operation, a secondary mucocele developed, accompanying headaches and facial pressure due to its continuous expansion. Despite numerous consultations, she refused surgical intervention until today.

Discussion

Early detection and removal of frontoethmoidal osteomas improves the prognosis for a favourable treatment outcome. The smaller the osteoma, the easier it can be removed endoscopically. The decision to perform surgery was made when the condition drastically affected the patient's quality of life. To date, there is still no strong consent regarding the best surgical approach and the best time to do it.

Conclusion

The combination of open and endoscopic surgery remains a safe and straightforward procedure for the removal of giant frontoethmoidal osteomas. Early detection and intervention are crucial for a predictable minimally invasive treatment with a favourable outcome for the patient.

•

Early removal of frontoethmoidal osteomas improves the prognosis for a favourable minimally invasive treatment outcome.

•

The smaller the osteoma, the easier it can be removed exclusively by endoscopy.

•

The combination of open and endoscopic surgery remains a safe and uncomplicated procedure for the removal of giant frontoethmoidal osteomas.
